Procedure
• 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.
Use the IXCMIAPU utility with the DELETE LOGSTREAM NAME(log_stream_name)
parameter specified to delete the log stream. The log dataset is deleted when the log stream
is deleted. For details, see the manual MVS Setting Up a Sysplex.

Re-defining the log stream when the event log is full
If a log dataset is full, execution of CLI commands will continue, but event log data will no longer be
output. To resume the output of event log data, suspend the CLI command, and then delete and
re-define the log stream.
Procedure
1. Suspend the CLI command.
2. Use the event log data output tool (KTLOGCP) to output all log data from the log stream to a
dataset.
3. Use the IXCMIAPU utility with the DELETE LOGSTREAM NAME(log_stream_name) parameter
specified to delete the log stream.
The log dataset is deleted when the log stream is deleted. For details, see the manual MVS Setting
Up a Sysplex.
4. Re-define the log stream.
5. Log on to TSO/E again and then execute the CLI command.

Restarting the system logger service and re-defining the log stream when the
event log is full
If a log dataset is full, execution of CLI commands will continue, but event log data will no longer be
output. The log stream cannot be deleted during execution of a CLI command. Therefore, if the CLI
command cannot be stopped when a log dataset is full, you can restart the system logger service and
then delete and re-define the log stream to resume the output of event log data.
