DELETE_LOG Command

Deletes all information about a specific PowerExchange Logger for z/OS log data set from the emergency restart data set (ERDS). Run this command periodically to delete information about obsolete archive log data sets.

Issue this command either by using the MVS MODIFY (F) command or by adding it to batch jobs that include log maintenance tasks.

Syntax

To issue the command with the MVS MODIFY command, use the following syntax:

F proc_name,DELETE_LOG DSN=data_set_name

The proc_name variable is the PowerExchange Logger procedure name.

To issue the command in batch mode, add the following control statements to a batch job:

DELETE_LOG
DSN=data_set_name
END

Parameter Descriptions

You can specify the following parameters for DELETE_LOG:

{DSN|DSNAME|LOG_DSNAME}: Specifies the fully-qualified data set name of the log data set for which you want to remove information from the ERDS. Maximum length is 44 characters.
END: Indicates the end of the DELETE_LOG control statement for a log data set in a batch job. Required for batch control statements only.

Usage Notes

If you use the MVS MODIFY command to run the DELETE_LOG command in interactive mode, the PowerExchange Logger can continue running.

If you run the DELETE_LOG command as part of a batch job, you must stop the PowerExchange Logger before the batch job runs. Also stop any ECCR that is running against data sources for which the PowerExchange Logger logs changes.

Example

Run the following command in batch mode to delete the archive log data set named PWXUSR1.ARCHLOG1.PWXL.LG1.D2007331.T1536523:

DELETE_LOG
DSNAME=PWXUSR1.ARCHLOG1.PWXL.LG1.D2007331.T1536523
END

The resulting output is:
