PowerProtect Data Manager Appliance 5.16.0.0 Oracle RMAN User Guide

Configure protection policy options

On the Options page, select any additional options that are required for the policy.

1. Archive Logs—Select the appropriate option for the deletion of archived logs:

   Option	Description
   Do not delete	Select this option to prevent the deletion of archived logs during backups. To delete the archived logs, the database administrator must run the delete command manually.
   Delete immediately after backup	Select this option to enable the deletion of archived logs immediately after all the backup types that are performed through the protection policy.
   Delete older than (days)	Select this option to enable the deletion of the available archived logs that are older than the specified number of days, for all the backup types that are performed through the protection policy. Set the number of days after which the archived logs are deleted.

2. Recovery Catalog Option—Only for centralized protection in an Oracle Data Guard environment, select the appropriate option for resynchronizing the recovery catalog with a database:

   Option	Description
   None	By default, the None value is selected. Select this value when the recovery catalog does not need to be automatically resynchronized with backup copies. This option applies to a non-Data Guard environment.
   Synchronous sync	Select this option to resynchronize the recovery catalog synchronously with backup copies after each backup.
   Asynchronous sync	Select this option to resynchronize the recovery catalog asynchronously with backup copies after each backup.

   In the Data Guard environment, it is recommended that you use a recovery catalog to manage the RMAN metadata for all physical databases, including both primary and standby databases. RMAN uses the recovery catalog as the single source of truth for the Data Guard environment.

   RMAN only automatically resynchronizes the recovery catalog with a database when connected to this database as TARGET. RMAN does not automatically resynchronize every database in the Data Guard environment when connected as TARGET to one database in the environment.

3. Files Per Set—Specify the maximum number of files that RMAN can include in a backup set. The value must be an integer between 1 and 64, inclusive.

   As an alternative to setting the options Files Per Set, Maximum Open Files, Block Size, and Section Size on the Options page, you can set the parameters FILESPERSET, MAXOPENFILES, BLOCK_SIZE, and SECTION_SIZE, respectively, in the configuration file rman_agent.cfg. The configuration file parameter settings take precedence over the option settings in the PowerProtect Data Manager Appliance UI. These parameter and option settings apply only to centralized backups.

   For Application Direct backups, the Files Per Set and Section Size settings apply only to full, incremental cumulative, and incremental differential backups—not to log backups.

   For Oracle Incremental Merge backups:

   • The option Block Size and parameter BLOCK_SIZE do not apply.
   • The option Files Per Set and parameter FILESPERSET apply only to archive log backups.
4. Maximum Open Files—Specify the maximum number of input files that a backup or copy can have open at a given time.
   The value must be an integer greater than 0.
5. Block Size—Specify the number of KB of data that the Oracle database reads for the backup operation.

   The value must be a multiple of the minimum physical block size of the Oracle database. The value must be <n>K, where <n> is an integer between 1 and 1024 inclusive. K means kilobytes.

   The option Block Size does not apply to Oracle Incremental Merge backups.

6. Section Size—Specify the size in KB, MB, or GB of each backup section in a multisection backup.

   In the backup set, each backup piece contains the blocks from one file section. The specified value must be <n>K or <n>M or <n>G, where <n> is an integer greater than 0. K means kilobytes, M means megabytes, and G means gigabytes.

   If you specify a section size that is larger than the size of the file, RMAN does not use a multisection backup for the file. If you specify a small section size that would produce more than 256 sections, RMAN increases the section size to a value that results in exactly 256 sections.

   NOTE:The Section Size option does not apply to multistream backups.
