This section provides an overview of the variables that can be configured for the AMM module with regards to the Primary Database. 

Note

Variables are sorted alphabetically in the table below

Variable Name

Meaning

ARCHSOURCE_BACKUP_COUNT

Specify the number of times an archive log has to be backed up by RMAN before Dbvisit Standby deletes it from the primary server.

To disable this setting, set to 0 which is the default value.

Example:

ARCHSOURCE_BACKUP_COUNT = 0

 

ARCHSOURCE_MANAGEMENT

Specify if the AMM module to manage the archive log files are turned on or off on the primary server.

Possible Values:

  • Yes (default)
    Enable the AMM module on primary server.

  • No
    Disable the AMM module on primary server.

Example:

ARCHSOURCE_MANAGEMENT= Yes

 

DAYS_TO_KEEP_ARCHSOURCE

Specify the number of days to keep the Oracle log files on the primary server. If this value (in days) are reached, the log files will be removed from the server.

To disable this setting, set to 0, if you are not sure, set to 7.

Note

Make sure you have sufficient disk space to store the archive logs.

See also the ARCHDEST parameter under the standby server variable section for more detail

 

Example:

DAYS_TO_KEEP_ARCHSOURCE = 7

 

DELETE_ARCHSOURCE

Specify if archive log files should be deleted once the percentage threshold (THRESHOLD_ARCHSOURCE) on the primary server is reached.

Once the threshold is reached oldest archive log files are deleted first. 

Note

There is no verification that these log files have been backed up. Dbvisit Standby does not perform backups, this should be configured outside the Dbvisit Standby product.

Possible Values:

  • Yes
    Let Dbvisit Standby delete archive log files once percentage threshold is met. 

  • No
    Dbvisit Standby will only alert when percentage threshold is met (no archive log files will be deleted). 

If you are not sure, set to No.

Example:

DELETE_ARCHSOURCE = No

 

Note

This setting has no influence whether (archive) log files are deleted for DAYS_TO_KEEP_ARCHSOURCE or NUM_ARCHSOURCE_TO_KEEP.

These settings will delete (archive) log files once the percentage threshold is met.

FRA_THRESHOLD_ARCHSOURCE

Specifies the threshold in percentage (%) of how much FRA (flash/fast recovery area) space may be taken up by the archive log files on disk before an alert is triggered on the primary server. A value of 80 means at 80% FRA space threshold is reached, an alert will be triggered.

Please specify threshold as an integer. 

Example:

   FRA_ THRESHOLD_ARCHSOURCE = 80

 

NUM_ARCHSOURCE_TO_KEEP

Specifies the number of archive log files to keep on the primary server. Log files greater than this number will be removed (oldest first).

To disable this setting, set to 0. If you are not sure, set to 0 (disable).

Example:

    NUM_ARCHSOURCE_TO_KEEP = 0

 

THRESHOLD_ARCHSOURCE

Specifies the threshold in percentage (%) of how much disk space may be taken up by the archive log files on disk before an alert is triggered on the primary server. A value of 80 means at 80% space threshold is reached, an alert will be triggered.

Please specify threshold as an integer. 

Example:

    THRESHOLD_ARCHSOURCE = 80
