Why don't ONLINE LOG JOBS KEPT plus ONLINE LOG JOBS DELETED match the total for ONLINE LOG JOBS READ?
The difference in the counts occurs because the MERGE and the RESET are processed separately.
After we have written all the records to the merge output file, we close the dataset logging file. We later reopen it to perform the RESET.
Between the CLOSE and the OPEN more records may be written to the log file, so the RESET has more records to process than the MERGE. So 'Delete' + 'Kept' may be greater than 'Online log jobs read'.
