Notes

See the online help that is provided with the administrative client for assistance with configuring the storage management information in your application groups.

The Content Manager OnDemand server programs can remain active while you run the ARSMAINT program. However, IBM® recommends that you schedule the ARSMAINT program to run at a time when little or no other Content Manager OnDemand activity takes place on the system.

IBM recommends that you do not load data on the system when you run the ARSMAINT program with the -r parameter.

It is recommended that you create a backup image of the Content Manager OnDemand database and the Tivoli® Storage Manager database before you run the ARSMAINT program.

The Content Manager OnDemand server program (ARSSOCKD or ARSOBJD in UNIX; LibSrvr or ObjSrvr in Windows) must be running, otherwise the ARSMAINT program will fail.

Before you can migrate index data, the index tables must be closed. To close a table to loading before the Maximum Rows value is reached, use the ARSTBLSP program with the -a 1 parameter. For more information, see ARSTBLSP.

If the Content Manager OnDemand cache file system becomes unavailable (as during a system failure), automatic retrieval from the archive storage might be possible, depending on the outage cause.

For example, assume that the HBA Adapter fails and causes the file systems to be unmounted. In this instance, the system looks in the cache first. If the file system is unmounted, the data will not be there, Content Manager OnDemand then looks in the archive storage (if the data was stored there). There are several other factors that might affect this function:
  • The file system is damaged, and commands such asls will not work.
  • Content Manager OnDemand does not look in the archive storage if there is an error reading the cache. The permissions of the unmounted file system are incorrect. AFP data has resources that are put back into the cache if they are ever removed.
  • The unmounted file system might not have enough storage space, so retrievals fail.

For the situations listed above, update the application group and turn off the search cache option. The search cache is located on the Storage Management tab of the application group properties. This causes Content Manager OnDemand to retrieve directly from the archive storage.
