Scenarios for resolving problems with client option sets

Edit online

Use client option sets to resolve various problems, from having critical environments where restoring is a high priority, to using a database that does not stop.

Tip: Trace settings for the client option sets are specified in the IBM Storage Protect option file for all backup-archive clients.

The following scenarios show you how you can take advantage of the client option set.

Scenario 1: Having an environment where restoring is a high priority.

Use the COLLOCATEBYFILESPEC option so that all filespec data is stored on as few tapes as possible, which enhances restore processing by using fewer tape mounts. You do not want the client to be able to override this option. Issue the following server command:

Define cloptset crit_rest description="Critical Restore Option Sets"
Define clientopt crit_rest collocatebyfilespec yes force=yes
Update node dale cloptset=crit_rest

Scenario 2: Using workstations that are on a slow network with limited space for data on the server.

Use the compression option to limit the amount of data that is sent and stored. Issue the following server command:

Define cloptset space_rest description="Space Restriction Option Sets"
Define clientopt space_rest compressalways no force=yes
Define clientopt space_rest compression yes force=yes
Update node mark cloptset=space_rest

Scenario 3: Using a database that does not stop.

A problem exists with the database because the files are open and the server cannot back them up. Exclude all files and subdirectories from IBM Storage Protect backups and add the files and subdirectories to the existing space_rest client option set. Issue the EXCLUDE DIR command and specify the directory path that is to be excluded. Issue the following server command:

Define clientopt space_rest inclexcl "exclude.dir c:\lnotes\data"

Scenario 4: Finishing backups using a fast network and wanting to make the best possible use of client resources.

Set the RESOURCEUTILIZATION option to the maximum amount. Issue the following server command:

Define cloptset unix_srv description="UNIX Server Option Sets"
Define clientopt unix_srv resourceutilization 10 force=yes
