Backing Up Oracle - Computing at Cornell

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.
