Configure Oracle-Managed Infrastructure Maintenance

Oracle performs the updates to all of the Oracle-managed infrastructure components on Oracle Exadata Database Service on Cloud@Customer.

Oracle performs periodic maintenance on your Exadata Cloud@Customer infrastructure to ensure it is free of potential issues that could affect database availability, integrity, and security. Updating the software running on the infrastructure with the latest product and security fixes protects your data and the overall compliance of the Oracle Cloud. These updates are performed in an automated way and include all the best practices, relieving you of the need to invest any effort in maintaining your infrastructure. Oracle updates include the physical database server hosts, storage servers, network fabric switches, management switches, power distribution units (PDUs), integrated lights-out management (ILOM) interfaces, and control plane servers.

Oracle performs two types of infrastructure maintenance. Quarterly maintenance is applied every three months and can include product fixes, enhancements, and security fixes. Monthly maintenance only applies critical security fixes that can be applied online to ensure components are maintained at the highest security standards with any security vulnerabilities fixed as soon as possible.

Oracle minimizes the impact on your applications using online and rolling maintenance operations. Quarterly updates are applied by default in a rolling manner (one server at a time - no downtime needed) with no database downtime preserving database availability throughout the update process. Applications designed for high availability should continue without disruption, eliminating the need for scheduling downtime. Monthly security updates are applied to database servers in an online manner, ensuring there is no disruption to any applications during monthly maintenance.

Oracle further reduces any impact of maintenance on your business by providing complete scheduling control of both Quarterly and Monthly maintenance, allowing you to schedule maintenance during a period when any impact of maintenance will have the least effect on your business users. You have full control and visibility over when quarterly maintenance will be applied, even allowing you to schedule the maintenance across multiple maintenance windows. The maintenance schedule can be modified if some unexpected business issue occurs that requires you to defer the maintenance. Monthly security maintenance can also be scheduled at a specific time during the month. Scheduling is simplified through the use of a Maintenance Scheduling Policy, which aims to standardize scheduling across the fleet to ensure consistency and efficiency. By defining the policy once and applying it to multiple resources, it streamlines the scheduling process.

You may manage contacts who are notified regarding infrastructure maintenance, set a maintenance window to determine the time your quarterly infrastructure maintenance will begin, and also view scheduled maintenance runs and the maintenance history of your Exadata Cloud@Customer in the Oracle Cloud Infrastructure Console. For details regarding the infrastructure maintenance process and configuring the maintenance controls refer to the following:

About Oracle Managed Oracle Exadata Database Service on Cloud@Customer Infrastructure Maintenance Updates

Oracle performs patches and updates to all of the Oracle-managed system components on Oracle Exadata Database Service on Cloud@Customer.

In all but rare exceptional circumstances, you receive advance communication about these updates to help you plan for them. If there are corresponding recommended updates for your VM cluster virtual machines (VMs), then Oracle provides notifications about them.

Wherever possible, scheduled updates are performed in a manner that preserves service availability throughout the update process. However, there can be some noticeable impact on performance and throughput while individual system components are unavailable during the update process.

For example, database server patching typically requires a reboot. In such cases, wherever possible, the database servers are restarted in a rolling manner, one at a time, to ensure that the service remains available throughout the process. However, each database server is unavailable for a short time while it restarts, and the overall service capacity diminishes accordingly. If your applications cannot tolerate the restarts, then take mitigating action as needed. For example, shut down an application while database server patching occurs.

Overview of the Quarterly Infrastructure Maintenance Process

By default, infrastructure maintenance updates the Exadata database server hosts in a rolling fashion, followed by updating the storage servers.

Rolling infrastructure maintenance begins with the Exadata database server hosts. For the rolling maintenance method, database servers are updated one at a time. Each of the database server host's VMs is shut down, the host is updated, restarted, and then the VMs are started, while other database servers remain operational. This rolling maintenance does not impact applications designed for high availability. Older applications not written to handle a rolling instance restart can be impacted. This process continues until all servers are updated.

After database server maintenance is complete, storage server maintenance begins. For the rolling maintenance method, storage servers are updated one at a time and this does not impact database or application availability. However, the rolling storage server maintenance can result in reduced IO performance as storage servers are taken offline one at a time (reducing available IO capacity) and resynced when brought back online (small overhead on database servers). Properly sizing the database and storage infrastructure to accommodate increased work distributed to database and storage servers that are not under maintenance will minimize (or eliminate) any performance impact.

You can also choose non-rolling maintenance to update database and storage servers. The non-rolling maintenance method first updates your storage servers at the same time, then your database servers at the same time. Although non-rolling maintenance minimizes maintenance time, it incurs full system downtime while the storage servers and database servers are being updated.

Note that while databases are expected to be available during the rolling maintenance process, the automated maintenance verifies Oracle Clusterware is running but does not verify that all database services and pluggable databases (PDBs) are available after a server is brought back online. The availability of database services and PDBs after maintenance can depend on the application service definition. For example, a database service, configured with certain preferred and available nodes, may be relocated during the maintenance and wouldn't automatically be relocated back to its original node after the maintenance completes. Oracle recommends reviewing the documentation on Achieving Continuous Availability for Your Applications on Exadata Cloud Systems to reduce the potential for impact to your applications. By following the documentation's guidelines, the impact of infrastructure maintenance will be only minor service degradation as database servers are sequentially updated.

Oracle recommends that you follow the Maximum Availability Architecture (MAA) best practices and use Data Guard to ensure the highest availability for your critical applications. For databases with Data Guard enabled, Oracle recommends that you separate the maintenance windows for the infrastructure instances running the primary and standby databases. You may also perform a switchover prior to the maintenance operations for the infrastructure instance hosting the primary database. This allows you to avoid any impact on your primary database during infrastructure maintenance.

Prechecks are performed on the Exadata Cloud@Customer infrastructure components prior to the start of the maintenance window. The goal of the prechecks is to identify issues that may prevent the infrastructure maintenance from succeeding. The Exadata infrastructure and all components remain online during the prechecks. An initial precheck is run approximately two weeks prior to the maintenance start and another precheck is run approximately 24 hours prior to maintenance start. If the prechecks identify an issue that requires rescheduling the maintenance notification is sent to the maintenance contacts.

The time taken to update infrastructure components varies depending on the number of database servers and storage servers in the Exadata infrastructure, the maintenance method, and whether custom action has been enabled. The approximate times provided are estimates. Time for custom action, if configured, is not included in the estimates below. Database server maintenance time may vary depending on the time required to shutdown each VM before the update and then start each VM and associated resources after the update of each node before proceeding to the next node. The storage server maintenance time will vary depending on the time required for the ASM rebalance, which is not included in the estimates below. If issues are encountered during maintenance this may also delay completion beyond the approximate time listed. In such a situation, if Oracle cloud operations determine resolution would extend beyond the expected window, they will send a notification and may reschedule the maintenance.

Overview of Monthly Security Maintenance

Security maintenance, performed alongside the quarterly maintenance, is executed in months when important security updates are needed and includes fixes for vulnerabilities across all CVSS scores.

Note

For more information about the CVE release matrix, see Exadata Database Machine and Exadata Storage Server Supported Versions (Doc ID 888828.1).

To view the CVE release matrix specific to an Exadata Infrastructure version, click the Exadata version, for example, Exadata 23. Version-specific CVE release matrices are listed in the Notes column of the table.

Security maintenance, when needed, is scheduled to be applied during a 21-day window that begins between the 18th-21st of each month and will run till the 9th-12th of the next month. Customers will receive notification of the proposed schedule at least 7 days before the start of the monthly maintenance window and can reschedule monthly maintenance to another date in the window if desired. The monthly security maintenance process updates the physical database servers to fix critical security vulnerabilities and critical product issues. Monthly maintenance also updates storage servers to an Exadata Storage Software image that resolves known security vulnerabilities and product issues. No updates are applied to the customer-managed guest VMs. Monthly maintenance also updates storage servers to an Exadata Storage Software image that resolves known security vulnerabilities and product issues.

Updates to database servers are applied online via Ksplice technology, and have no impact to workloads running on the compute (database) servers, as database server security updates are applied online to the host server while your VM and all processes within the VM, including databases, remain up and running. Servers and VMs are not restarted. Updates to storage servers are applied in a rolling fashion. As with quarterly maintenance, the impact of rebooting storage servers should be minimal to applications.

While updating your services infrastructure, some operations including memory, and storage scaling, operating system and Grid Infrastructure patching (including prechecks), and elastic expansion of compute and storage servers may be blocked.
Note

CPU scaling and VM startup/shutdown are the only operations supported during monthly infrastructure maintenance.
Please plan to defer these operations until after the updates are complete. . If you attempt an affected operation, the console will notify you of the ongoing security updates. No software is updated in the guest VMs.

Understanding Monthly and Quarterly Maintenance in the Same Month

Special considerations are made when both quarterly and monthly security maintenance are scheduled to run in the same month. Quarterly maintenance will reapply any security fixes already applied by security maintenance, and neither quarterly nor monthly maintenance will apply a storage server update if the existing storage server version is the same or newer than the version contained in the update.

  • The contents of the updates applied during quarterly maintenance are determined at the start of the maintenance quarter and use the latest Exadata release from the month prior to the start of the maintenance quarter. If any additional security fixes are available at that time, those updates are included in the quarterly maintenance. That image is then used throughout the quarter. For example, the January release is used for quarterly maintenance in Feb, March, and April.
  • When quarterly maintenance is applied it is possible there are security updates previously installed on the database servers are not included in the quarterly maintenance release to be applied. In that case, the automation will apply the same security fixes to new release installed by the quarterly maintenance so there will not be any regression in security fixes. If the current image on the storage server is the same or newer than that to be applied by the quarterly or monthly security maintenance, that maintenance will be skipped for the storage servers.

If quarterly maintenance is scheduled within 24 hours of the time the monthly is scheduled, the scheduled monthly maintenance will be skipped, and the monthly update will instead be applied immediately following the quarterly maintenance.

  • When scheduled at the same time, the monthly update is executed immediately following the completion of the quarterly maintenance.
  • If monthly maintenance is scheduled to begin 0-24 hours ahead of the quarterly maintenance, then the monthly maintenance will not execute as scheduled, but instead, wait and be executed immediately following the quarterly maintenance. If the quarterly maintenance is subsequently rescheduled, then the monthly security maintenance will begin immediately. Oracle, therefore, recommends scheduling quarterly and monthly maintenance at the same time. As a result, if you reschedule the quarterly at the last moment, the monthly maintenance will run at the scheduled time instead of immediately upon editing the schedule. You can also reschedule the monthly security maintenance when rescheduling the quarterly maintenance as long as you keep the monthly within the current maintenance window. Monthly maintenance can be rescheduled to another time in the maintenance window, but cannot be skipped.

Monthly Security Maintenance before Quarterly Maintenance

  • To apply security maintenance before quarterly maintenance, reschedule the monthly security maintenance to occur more than 24 hours prior to the quarterly maintenance. The security maintenance will online apply security patches to the database servers with no impact to applications, and apply an update to the storage servers with minimal to no impact (may be slight performance degradation) on applications. The quarterly maintenance will follow as scheduled, and will perform rolling maintenance on the database servers, which will impact applications not written to handle a rolling reboot. As part of the quarterly maintenance, it will apply the same security updates to the database server that are already installed on the system (no security regression).
  • If you are concerned about getting the latest security updates applied, schedule the monthly security maintenance to run after the new monthly maintenance window opens (usually on the 21st of the month).
  • The impact of the monthly security maintenance rebooting the storage servers should be minimal, so impact to the applications during this month will only be due to the restart of the database servers during the quarterly maintenance. However, if you must coordinate a maintenance window with your end users for the security maintenance, this will require two maintenance windows.

Quarterly Maintenance before Monthly Security Maintenance

  • To run the quarterly maintenance before the monthly security maintenance, reschedule the security maintenance to run no earlier than 24 hours before the quarterly maintenance is scheduled to start. The security maintenance will be deferred until the quarterly maintenance is completed. The quarterly maintenance will perform rolling maintenance on the database servers, which will impact applications not written to handle a rolling reboot. The quarterly maintenance may or may not skip the storage server patching. That depends on if it is newer or older than the release currently installed. In most cases, the version installed should be newer than the version associated with the quarterly maintenance. Exceptions to this rule may occur if it is the first month of a maintenance quarter, or you skipped the security maintenance in one or more prior months. The security maintenance will run either immediately after the quarterly maintenance is completed, or when scheduled, whichever is later. It will apply online updates to the database servers (no application impact) and will likely update the storage servers in a rolling manner. In some corner cases. the quarterly maintenance may contain the same storage server release as the security maintenance and the security maintenance storage server updates will be skipped.
  • The impact to end users of running the quarterly maintenance before the security maintenance should be roughly the same as running the security maintenance first. The quarterly maintenance will be a disruptive event, but the security maintenance rebooting the storage servers should cause minimal disruption, and the security maintenance is applied to the database servers online. However, if you must coordinate a maintenance window with your end users for the security maintenance, this will require two maintenance windows. You can schedule those two maintenance windows to run back-to-back, to appear as single maintenance window to end users. To do this, reschedule the security maintenance to start at the same time (or up to 24 hours prior) as the quarterly maintenance. The security maintenance will be deferred until the quarterly maintenance is completed. Assuming you have been regularly applying monthly security maintenance, the storage servers will be skipped by the quarterly maintenance and will be updated by the security maintenance immediately upon the completion of the quarterly maintenance.

Minimizing Maintenance Windows

  • To minimize the number of maintenance windows (you have to negotiate those with end users), schedule the quarterly maintenance and monthly maintenance at the same time. The security maintenance will be blocked. The quarterly maintenance will update the database servers in a rolling manner and will most likely skip the storage server. The security maintenance will follow up immediately and update the database servers online and the storage servers in a rolling manner. The result is a single database and storage server restart in a single maintenance window.
  • There are two exceptions to this. 1. If the quarterly and monthly maintenance contain the same storage server release, the quarterly maintenance will apply the storage server update, and the security maintenance will be skipped. From your perspective, this is still a single rolling reboot in a single maintenance window. 2. The currently installed release on the storage servers is older than that contained in the quarterly maintenance, which in turn is older than that in the security maintenance. That would cause the quarterly maintenance to update the storage, and then the security maintenance to do it as well. This can only happen if you skipped a prior month's security maintenance, because it requires the current image to be at least 2 months out of date. In such a scenario, you may want to schedule the security maintenance first and then the quarterly maintenance. This would result in one storage server reboot, but two distinct maintenance windows — the first for the security maintenance, and then later the quarterly maintenance.
  • To minimize the impact to your end users, always apply the monthly security updates, and in months where both are scheduled, schedule them at the same time.
Note

  • If the Exadata Infrastructure is provisioned before Oracle schedules the security maintenance, then it will be eligible for security maintenance.
  • Any time before the scheduled monthly Exadata Infrastructure maintenance, you can reschedule it.

Infrastructure Maintenance Contacts

Maintenance contacts are required for service request based communications for hardware replacement and other maintenance events.

Add a primary maintenance contact and optionally add a maximum of nine secondary contacts. Both the primary and secondary contacts receive all notifications about hardware replacement, network issues, and software maintenance runs.

You can promote any secondary contacts as the primary anytime you want. When you promote a secondary contact to primary, the current primary contact will be demoted automatically to secondary.

For more information, see: Using the Console to Create Infrastructure and Managing Infrastructure Maintenance Contacts.

Maintenance Scheduling Policy

Learn how to use the OCI Console to configure and manage maintenance scheduling policies. If a maintenance scheduling policy is used, all the scheduling preferences for the infrastructure maintenance are derived from the policy.

The Maintenance Scheduling Policy aims to standardize scheduling across the fleet, ensuring consistency and efficiency. By defining the policy once and applying it to multiple resources, it streamlines the scheduling process. The policy aligns with business best practices, scheduling maintenance activities in accordance with these standards. It also serves as a central repository for documenting and coordinating maintenance commitments with various stakeholders, enhancing compliance and efficiency. The centralized management of resources subscribing to the policy ensures adherence to compliance requirements, and any changes can be efficiently coordinated from a single location. Additionally, the policy improves communication about planned maintenance across different environments in the fleet, facilitating better coordination and awareness.

Note

If you use a scheduling policy, scheduling preferences defined locally on the infrastructure are not used by Oracle automation to apply quarterly updates.

Using the Console to Configure Oracle-Managed Infrastructure Updates

Full Exadata infrastructure software updates are scheduled on a quarterly basis. In addition, important security updates are scheduled monthly. While you cannot opt-out of these infrastructure updates, Oracle alerts you in advance through the Cloud Notification Portal and allows scheduling flexibility to help you plan for them.

For quarterly infrastructure maintenance, you can set a maintenance window to determine when the maintenance will begin. You can also edit the maintenance method, enable custom action, and view the scheduled maintenance runs and the maintenance history of your Exadata Cloud@Customer in the Oracle Cloud Infrastructure Console. For security maintenance, you may edit the scheduled start time within the 21-day window.

  5. Click Edit Maintenance Preferences.

    Edit Maintenance Preferences page is displayed.

    Note

    Changes made to maintenance preferences apply only to future maintenance, not the maintenance that has already been scheduled. To modify scheduled maintenance, see View or Edit a Scheduled Maintenance for Exadata Cloud@Customer Infrastructure.

  6. On the Edit Maintenance Preferences page, configure the following:
    • Maintenance scheduling preference: Oracle managed schedule
      • Choose a maintenance method:
        • Rolling: By default, Exadata Infrastructure is updated in a rolling fashion, one server at a time with no downtime.
        • Non-rolling: Update database and storage servers at the same time. The non-rolling maintenance method minimizes maintenance time but incurs full system downtime.
      • Enable custom action before performing maintenance on DB servers: Enable custom action only if you want to perform additional actions outside of Oracle’s purview. For maintenance configured with a rolling software update, enabling this option will force the maintenance run to wait for a custom action with a configured timeout before starting maintenance on each DB server. For maintenance configured with non-rolling software updates, the maintenance run will wait for a custom action with a configured timeout before starting maintenance across all DB servers. The maintenance run, while waiting for the custom action, may also be resumed prior to the timeout.

        • Custom action timeout (in minutes): Timeout available to perform custom action before starting maintenance on the DB Servers.

          Note

          Custom action timeout applies only to DB servers. Customer can specify a minimum 15 minutes and a maximum of 120 minutes of custom action time-out before DB server patching starts. Within this time, they can perform whatever actions they have planned. In case, they want to extend the custom action, they can extend the same by going to "edit maintenance window" option. If custom action is in progress, customer get 2 options - either extend Custom action timeout or resume maintenance window.

          Default: 15 minutes

          Maximum: 120 minutes

      • Click Save Changes.
        Note

        From the next maintenance run onwards, executions will occur according to Oracle's schedules.
    • Maintenance scheduling preference: Customer managed schedule
      • Maintenance schedule: Define maintenance preferences for this infrastructure.
        Note

        Changes will take effect from the next maintenance run.
        • Configure maintenance preference: Define maintenance time preferences for each quarter. If more than one preference is defined for a quarter, Oracle automation will select one of them to perform maintenance on all components in your infrastructure.

          Select at least one month every two quarters.

        • Specify a schedule: Choose your preferred week, weekday, start time, and lead time for infrastructure maintenance.
          • Optional. Under Week of the month, specify which week of the month, maintenance will take place. Weeks start on the 1st, 8th, 15th, and 22nd days of the month, and have a duration of 7 days. Weeks start and end based on calendar dates, not days of the week. Maintenance cannot be scheduled for the fifth week of months that contain more than 28 days. If you do not specify a day of the week, then Oracle will run the maintenance update on a weekend day to minimize disruption.
          • Optional. Under Day of the week, specify the day of the week on which the maintenance will occur. If you do not specify a day of the week, Oracle will run the maintenance update on a weekend day to minimize disruption.
          • Optional. Under Hour of the day, specify the hour during which the maintenance run will begin. If you do not specify a start hour, Oracle will pick the least disruptive time to run the maintenance update.
          • Under Notification Lead Time, specify the minimum number of weeks ahead of the maintenance event you would like to receive a notification message. Your lead time ensures that a newly released maintenance update is scheduled to account for your required minimum period of advanced notification.
        • Choose a maintenance method:
          • Rolling: By default, Exadata Infrastructure is updated in a rolling fashion, one server at a time with no downtime.
          • Non-rolling: Update database and storage servers at the same time. The non-rolling maintenance method minimizes maintenance time but incurs full system downtime.
        • Enable custom action before performing maintenance on DB servers: Enable custom action only if you want to perform additional actions outside of Oracle’s purview. For maintenance configured with a rolling software update, enabling this option will force the maintenance run to wait for a custom action with a configured timeout before starting maintenance on each DB server. For maintenance configured with non-rolling software updates, the maintenance run will wait for a custom action with a configured timeout before starting maintenance across all DB servers. The maintenance run, while waiting for the custom action, may also be resumed prior to the timeout.
          • Custom action timeout (in minutes): Timeout available to perform custom action before starting maintenance on the DB Servers.
            Note

            Custom action timeout applies only to DB servers. Customer can specify a minimum 15 minutes and a maximum of 120 minutes of custom action time-out before DB server patching starts. Within this time, they can perform whatever actions they have planned. In case, they want to extend the custom action, they can extend the same by going to "edit maintenance window" option. If custom action is in progress, customer get 2 options - either extend Custom action timeout or resume maintenance window.

            Default: 15 minutes

            Maximum: 120 minutes

        • Show advanced options:
          • Enable monthly security infrastructure maintenance: Select this check box to perform monthly security infrastructure maintenance.
      • Maintenance schedule: Use maintenance window preferences from a scheduling policy

        During infrastructure provisioning, after the scheduling policy is selected, Oracle generates a recommended maintenance scheduling plan to apply updates to all the components in your infrastructure. The recommended plan schedules all DB Servers, followed by Storage Servers and Network Switches, into the maintenance windows from your policy based on duration. After provisioning the infrastructure, you can update the scheduling plan by editing the 'Maintenance Scheduling Plan' resource and customize the update to specific components to align with different windows in your scheduling policy.

        • Click Select policy.
        • In the resulting Select maintenance scheduling policy window, choose a compartment and a policy.

          You can also create a maintenance scheduling policy and use it. For more information, see Create a Maintenance Scheduling Policy. Note that you can add additional maintenance windows to the policy after creating it. For more information, see Add Additional Maintenance Windows to a Maintenance Scheduling Policy.

        • Click Save changes.
          Note

          Changes will take effect from the next maintenance run.

          You must confirm your choice by entering the currently used policy name in a confirmation dialog before making any changes that delete the associated maintenance plan created with the attached policy.

          • Changing from one scheduling policy to another scheduling policy after the recommended maintenance plan is created and saved for the infrastructure
          • Changing from using a scheduling policy to not using a policy and defining your maintenance preference in line with your infrastructure
          • Change from using the scheduling policy to not using the policy and apply updates as per the Oracle-managed schedule.

          All of the above changes delete the scheduling plan for your infrastructure created with the current policy, and you will lose any customizations made to the Oracle recommended plan if you attach the same policy later.

For maintenance configured with a rolling software update, enabling this option will force the maintenance run to wait for a custom action with a configured timeout before starting maintenance on each DB server. For maintenance configured with non-rolling software updates, the maintenance run will wait for a custom action with a configured timeout before starting maintenance across all DB servers. The maintenance run, while waiting for the custom action, may also be resumed prior to the timeout.

                • Custom action timeout (in minutes): Timeout available to perform custom action before starting maintenance on the DB Servers.

                  Note

                  Custom action timeout applies only to DB servers. Customer can specify a minimum 15 minutes and a maximum of 120 minutes of custom action time-out before DB server patching starts. Within this time, they can perform whatever actions they have planned. In case, they want to extend the custom action, they can extend the same by going to "edit maintenance window" option. If custom action is in progress, customer get 2 options - either extend Custom action timeout or resume maintenance window.

                  Default: 15 minutes

                  Maximum: 120 minutes

            • Add DB Servers:
              • Select DB Servers: Updates to selected DB Servers will be moved from their currently scheduled window to the window you are adding the maintenance action.
          • Storage Server Exadata full software update
            • Configure maintenance method:
              • Rolling: By default, Exadata Infrastructure is updated in a rolling fashion, one server at a time with no downtime.

              • Non-rolling: Update database and storage servers at the same time. The non-rolling maintenance method minimizes maintenance time but incurs full system downtime.

                Note

                All storage servers in the infrastructure must be scheduled to update in a single maintenance action to apply non-rolling storage updates. While these updates are applied, your database workloads will incur complete downtime.
            • Select storage server from: Select a window from where you want to add storage servers from.
            • Select maintenance action to add from: Select the action from where you want to add storage servers from.
            • Select number of storage servers to add: Select the number of storage servers to add to this action.
          • Network switch software update: A banner with the message "Network switch update is already scheduled for the selected maintenance window." if the network switch software update is already scheduled in the chosen maintenance window.
      • Move action from another window: When you are moving an action, you can choose to move all components scheduled to update in a specific window to a new window.
        • Select the window to move action from: Choose a window from the maintenance run.
        • Select the action to move: Choose a specific action from the maintenance window to move.
  8. To delete an action:
    1. Click the Actions menu (three dots) of the maintenance action, and then select Remove.
      Note

      • Any action can be removed as long as there are no components scheduled for update in that action.
      • Any window can be removed as long as there are no actions scheduled for update in that window.

Review and Respond to Unplanned Maintenance Activity

After scaling your infrastructure by adding DB or storage servers, you may need to update your maintenance scheduling plan to include these new components. If any infrastructure component is missing from the maintenance plan, a warning will appear in the infrastructure maintenance plan details section.

When Oracle automation creates the maintenance run for the quarter, any components not included in the maintenance plan will be automatically added to an 'Unplanned' maintenance window. This ensures that all components have the correct system software applied each quarter, maintaining OCI software compliance.

You can edit the scheduled start time of the 'Unplanned' window or move the updates for the missing components to an existing planned window as needed.

If a scheduled update fails, the Oracle operations team will engage, evaluate the failure, and reschedule the failed update along with any unfinished updates to a future maintenance window. Oracle automation will mark this rescheduled window as 'Unplanned' and notify you to review the rescheduled maintenance activity.

You can edit the 'Unplanned' window's scheduled start time or move the failed and unfinished updates to an existing planned window as needed.

For maintenance windows configured with duration enforcement, Oracle automation will check if the estimated time to execute and apply the scheduled update is sufficient within the remaining window duration. If not, Oracle automation will automatically reschedule all unfinished updates to a future 'Unplanned' window, mark the current window as 'Duration Exceeded,' and notify you to review the rescheduled maintenance activity.

Any updates already in progress will continue past the enforced window duration to ensure a consistent state of the underlying resources.

Monitor Infrastructure Maintenance Using Lifecycle State Information

The lifecycle state of your Exadata Infrastructure resource enables you to monitor when the maintenance of your infrastructure resource begins and ends.

In the Oracle Cloud Infrastructure Console, you can see lifecycle state details messages on the Exadata Infrastructure Details page when a tooltip is displayed beside the Status field. You can also access these messages using the ListExadataInfrastructures API, and using tools based on the API, including SDKs and the OCI CLI.

During infrastructure maintenance operations, you can expect the following:
  • If you specify a maintenance window, then patching begins at your specified start time. The infrastructure resource's lifecycle state changes from Available to Maintenance in Progress.
    Note

    The prechecks are now done prior to the start of the maintenance.
  • When Exadata database server maintenance starts, the infrastructure resource's lifecycle state is Maintenance in Progress, and the associated lifecycle state message is, The underlying infrastructure of this system (dbnodes) is being updated.
  • When storage server maintenance starts, the infrastructure resource's lifecycle state is Maintenance in Progress, and the associated lifecycle state message is, The underlying infrastructure of this system (cell storage) is being updated and this will not impact Database availability.
  • After storage server maintenance is complete, the networking switches are updated one at a time, in a rolling fashion.
  • When maintenance is complete, the infrastructure resource's lifecycle state is Available, and the Console and API-based tools do not provide a lifecycle state message.

Receive Notifications about Your Infrastructure Maintenance Updates

There are two ways to receive notifications. One is through email to infrastructure maintenance contacts and the other one is to subscribe to the maintenance events and get notified.

Oracle schedules maintenance run of your infrastructure based on your scheduling preferences and sends email notifications to all your infrastructure maintenance contacts. You can login to the console and view details of the schedule maintenance run. Appropriate maintenance related events will be generated as Oracle prepares for your scheduled maintenance run, for example, precheck, patching started, patching end, and so on. For more information about all maintenance related events, see Oracle Exadata Cloud@Customer Events. In case, if there are any failures, then Oracle reschedules your maintenance run, generates related notification, and notifies your infrastructure maintenance contacts.

For more information about Oracle Cloud Infrastructure Events, see Overview of Events. To receive additional notifications other than the ones sent to infrastructure maintenance contacts, you can subscribe to infrastructure maintenance events and get notified using the Oracle Notification service, see Notifications Overview.
