Enabled: Enables the file watcher. (Causes the DBMS_SCHEDULER.ENABLE procedure to be called after the file watcher is created.)

Name: Name of the file watcher.

Description: Optional descriptive text.

Destination: Name of an external destination. You create an external destination by registering a remote Scheduler agent with the database.The view ALL_SCHEDULER_EXTERNAL_DESTS lists valid external destination names. If this parameter is null, the file watcher is created on the local host.

Credential Name: Name of a valid credential object. The file watcher uses the credential to authenticate itself with the host operating system to access the watched-for file. The file watcher owner must have EXECUTE privileges on the credential.

Directory Path: Directory in which the file is expected to arrive. The single wildcard '?' at the beginning of the path denotes the Oracle home path. For example, '?/rdbms/log' denotes the rdbms/log subdirectory of the Oracle home directory.

File Name: Name of the file to look for. Two wildcards are permitted anywhere in the file name: '?' denotes any single character, and '*' denotes zero or more characters.

Min File Size: Minimum size in bytes that the file must be before the file watcher considers the file found.

Steady State Duration: Minimum time interval that the file must remain unchanged before the file watcher considers the file found. Cannot exceed one hour. If null, an internal value is used. The minimum value is 10 seconds. Oracle recommends similar steady state duration values for all file watchers for efficient file watcher job operation. Also, the repeat interval of the file watcher schedule must be equal or greater than the steady state duration value.
