Define Tivoli Storage Manager policy requirements

RMAN uses the format parameter in the RMAN script to generate unique backup file names. Because all backup objects inserted into the Tivoli Storage Manager backup storage pool have unique file names, they never expire on the Tivoli Storage Manager server. As a result, Data Protection for Oracle requires the following Tivoli Storage Manager policy domain settings:

Backup copy group values

Data Protection for Oracle provides the tdposync utility to remove unwanted backup objects from the Tivoli Storage Manager server. Set the following Tivoli Storage Manager backup copy group options:

• verdeleted 0
• retonly 0

When Data Protection for Oracle marks a backup object inactive, that object is deleted from the Tivoli Storage Manager server the next time expiration processing occurs. A backup object is marked for immediate expiration when you delete it through RMAN with the Data Protection for Oracle interface or with the tdposync utility. Note, an inactive backup object cannot be restored through RMAN with the Data Protection for Oracle interface.

Note:

1. The Tivoli Storage Manager administrator must also register your node by specifying backdelete yes in order for backup objects to be deleted. However, be aware that a backup object is marked for immediate expiration when backdelete yes and you delete it through RMAN with the Data Protection for Oracle interface or with the tdposync utility. Note, when backdelete no is specified and a deletion request is made, the request fails and an error message displays.
2. The following backup copy group options are not applicable to Data Protection for Oracle:
   • frequency
   • verexists
   • retextra
   • mode
   • serialization
   Data Protection for Oracle accepts default values for these options.
3. An archive copy group is not required (although it can exist) because Data Protection for Oracle stores all objects as backup objects on Tivoli Storage Manager.

Management class

Tivoli Storage Manager uses management classes to manage backups on the Tivoli Storage Manager server. When you back up a database, the default management class for your node is used. Because the policy requirements for Data Protection for Oracle might be different from the wanted settings for the regular Tivoli Storage Manager backup-archive clients, you must have a different management class that is defined for Data Protection for Oracle. You must define a separate policy domain where the default management class has the required settings. Then, register all Data Protection for Oracle nodes to that domain.

If you choose to define a new management class within an existing policy domain, not the default management class for that domain, then you must add an include statement to the Data Protection for Oracle options file to bind all objects to that management class.

The following steps assign a management class name orcbackup to all Oracle backups with a default file space name adsmorc:

1. Add this inclexcl entry under the server stanza you use in the dsm.sys file:

     inclexcl /u01/oracle/include.def

2. Add this inclexcl entry under the server stanza you use in the dsm.opt file:

   inclexcl C:\myfile\include.def

3. Add the following include entry to the /u01/oracle/include.def file:

     include /adsmorc/.../* orcbackup

   Add the following include entry to the C:\myfile\include.def file:

     include \adsmorc\...\* orcbackup

   Note: The file space name in the include/exclude statement must match the file space name that is defined with the tdpo_fs option. If a file space name other than the default value adsmorc is used:

   1. You must specify the file space name with the tdpo_fs option.
   2. You must specify the file space name that is defined in the tdpo_fs option in the include/exclude statement.

All the files that are backed up with a default file space name of adsmorc are assigned to management class orcbackup.
