Reorganization of Send and Receive Log file
Even if the above Log record deletion (by manual operation) or Log record deletion (by automatic execution) is executed, an increase of unused space of DASD may cause problems of operation efficiency.
We recommend that you reorganize the log files after you delete their log records.
