4.7 Policy management considerations When deciding how to set up your TSM server to store Oracle backup objects, you need to decide on how you are going to organize your nodes into domains. You must also correctly define and configure your management classes. 4.7.1 Domain considerations You can use one domain for all your client data or you can specify multiple TSM domains to group nodes with the same backup characteristics together. Using multiple domains helps ensure that the data objects get bound to the appropriate management class. The following are some items to consider if you wish to use multiple domains: Backup-archive client, API client Platforms separated, such as AIX, Sun, Windows Critical data, non-critical data Group nodes with the same data characteristics together Because the policy requirements for Oracle backups are different from the desired settings for regular TSM backup clients, a different management class must be defined within TSM for managing these Oracle backups. There are two ways to implement this different management class setup: Define a new management class within an existing policy domain. Define a separate policy domain where the default management class contains the required settings. 4.7.1.1 Define a new management class in an existing domain If you choose to define a new management class within an existing policy domain (which is not the default management class for that domain), then you must add an include statement in the client options file (dsm.opt for Windows, dsm.sys for UNIX) that is used by the Oracle node. This include statement binds the Oracle backup objects to that management class that you have defined for managing these backups. The include statement would look similar to this: include * ManagementClassName 4.7.1.2 Define a separate policy domain The recommended way is to define a separate policy domain where the default management class has the required settings. Then just register the node that will be used for Oracle backups to this new domain. 48 Backing Up Oracle using Tivoli Storage Management
If the node is already defined, the Update Node command can be used to move the node to this new domain. This method allows the default management class to be utilized for the Oracle backups. There is no concern over an include statement not being recognized during the backup process. 4.7.2 TSM management class considerations This section describes how the management class and its associated copygroups should be configured. 4.7.2.1 Backup copy group considerations. Normally TSM backup copy groups are designed to hold multiple versions of files and directories in order to restore not only the latest (active) but also older versions that had been changed or deleted (inactive). TDP for Oracle will send backups through the TSM client API directly to the backup copy group of the default management class to which the node is assigned. Oracle assigns unique names to every database backup. The settings that pertain to multiple versions do not apply. The following retention settings should be used for the management class that will be bound to the Oracle backups. VEREXISTS=1 Keeps only one version of the backup file as the name of the backup is unique. (There will not be a newer version of the backup image with the same name). VERDELETED=0 If the backup file has been deleted then TSM should not keep an inactive version of this file. RETEXTRA=0 (the same value as RETONLY) This parameter will never be used as you will never have more than one version of the backup file. To prevent confusion set this parameter to the same value as RETONLY. RETONLY=0 When a backup image file becomes inactive it will be purged from the TSM server at the next expiration. 4.7.2.2 Archive copy group considerations Archive copy groups are designed to hold archive objects for a dedicated time and than to automatically delete the object.
