Activity log information for the System Programmer

The command activity log contains detailed messages with which a system programmer determines system error conditions. Each message is date-stamped and time-stamped indicating when the message was issued. A header and trailer message indicates the span of time that is covered by the log.

The activity logs are not the same as the DFSMShsm log that is used for maintenance. The activity logs verify that DFSMShsm is performing as you expect.

The migration, backup, and dump activity logs receive records for automatic volume functions and for command volume functions. Each receives:

A record for the start of each automatic function
A record for the end of each automatic function
A record for the start of each volume
A record for the end of each volume

In addition, the backup and migration logs can receive an ARC0734I message for each data set that is processed.
