Preventing the event log from becoming full when the system logger service is
used
This subsection describes how to prevent the event log from becoming full when the system logger
service is used.
If a log dataset is full, execution of a CLI command will continue, but event log data will no longer
be output. Use either of the following management methods to prevent the log dataset from becoming
full.
• Automatically delete event log data (specify the AUTODELETE(YES) parameter when defining
the log stream).
• Periodically delete and re-define the log stream.
