Create only one ARCHIVE statement per ARCMAIN script. ARCMAIN scripts that contain multiple ARCHIVE statements might create a valid backup even though the first statement fails. In other words, if a first statement fails when the second statement is valid, the second statement creates a backup. To consider both backups as a single logical set, manually edit the ARCMAIN job to only process the first ARCHIVE statement, then resubmit the job.
To avoid having to manually edit and resubmit jobs due to multiple statements and generated errors, code only a single ARCHIVE statement in an ARCMAIN script.
