Configuring the System Log application group

The system log is comprised of the System Log application group, a set of System Log applications, and the System Log folder. The System Log application group contains the storage management information that Content Manager OnDemand uses to maintain the data written to the system log. When you initialize the system, the application group is not assigned to a migration policy and storage set. Because the application group is not assigned to a storage set, the system does not migrate a copy of the system log data to archive media.

IBM® recommends that, before you begin defining reports to Content Manager OnDemand, loading data into the system, or allowing users to access the system, you configure the System Log application group to maintain a permanent copy of the data that is written to the system log. You can do this by first defining a migration policy (and its corresponding storage set) that specifies archive storage media such as disk pool, optical, or tape, and then by updating the System Log application group and assigning it to the storage set.

No matter where you decide to keep your System Log data, it is important to note that searching the System Log is one of a number of ways to locate the Load ID for archived data. Every time data is loaded into Content Manager OnDemand, message number 87 is placed in the System Log, and the Load ID is recorded as part of that message. The Load ID (also called "Report ID") is a required parameter for the Remove Report (RMVRPTOND) and Print Report (PRTRPTOND) commands.
