Maintaining system log data in archive storage

IBM® recommends that you create a migration policy that specifies archive storage media. You must add at least one primary storage location to the migration policy. The primary storage location must identify archive storage media to maintain data indefinitely.

About this task

After you create the migration policy (which automatically creates a storage set with the same name) you must update the System Log application group and assign it to the storage set. After assigning the application group to the storage set and restarting the server, the system automatically maintains a copy of the system log data in the archive storage you have specified.

Procedure

After you create the migration policy, complete the following steps to assign the System Log application group to a storage set:

  1. Start the Content Manager OnDemand Administrator client.
  2. Log on to the server with a user ID that has system administrator authority. (The default user named QONDADM has system administrator authority.)
  3. Click Application Groups.
  4. Right-click on the System Log application group.
  5. From the pop-up menu, select Update to open the Update an Application Group window.
  6. Click the Storage Management tab.
  7. In the Storage Set Name list, select the name of the storage set. The storage set name selected should match the migration policy definition created for your System Log data.
  8. Under Cache Data, specify at least 1 day for the Cache Document Data for x Days value. The System Log application group is created with a default value of 10000 days in cache. You can reduce this number when setting up the System Log application group to use a Storage Set. You must specify at least 1 day in cache so that the system log entries are appended to previous entries each day, for more efficient storage management, prior to them being sent to the storage manager.
  9. Click Advanced to open the Advanced Storage Management dialog box.
  10. Select Next Cache Migration under Migrate Data from Cache. Content Manager OnDemand copies the system log data to archive storage the next time the maintenance commands execute. You can also select After x days in cache if you want your system log data to stay in cache (on disk) for some period of time before it is copied to your archive storage. You can select Next Cache Migration or After x Days in Cache instead of When Data is Loaded so that the system log entries are appended to previous entries each day for more efficient storage management, prior to them being sent to the storage manager.
  11. Click OK to close the Advanced Storage Management dialog box.
  12. Click OK to save your changes and close the Update an Application Group window.
