To delete a log data set use one of the methods for making the offload data set eligible for deletion as described in Deleting log data, then either wait or cause a logger offload and data set switch to occur or cause the application to disconnect from the logstream.

Disconnecting from the logstream may cause offload processing to occur. Offload processing may cause a data set switch to occur. Data set switch processing may decide to delete log data sets if they meet all of the eligibility requirements.

The deletion of the log stream definition from the LOGR policy will cause the deletion of all the offload data sets associated with the deleted log stream. See Deleting log streams from the LOGR policy and When is my log data or log data set physically deleted?.

Note that IBM® does not suggest other methods for deleting data sets, such as the TSO/E DELETE command, because system logger cannot perform any clean-up and the deleted data sets will still count toward the data set directory limit.
