DFS4606I COULD NOT DELETE THE BLOCKS FOR DEDB ALTER DEDB=dddddddd RC=rrrrrrrr RSN=aaaaaaaa MODULE=bbbbbbbb
Explanation
During IMS restart, IMS detected that the DEDB Alter utility was running when IMS abnormally terminated. The ACTIVE ACBLIB contained an encrypted member, which IMS was unable to delete. The RC is set by DBFMOLS0 during the UNDO COPYLBOCKs call. The RSN code identifies from where in the code the message was issued.
System action
Emergency restart continues.
System programmer response
Verify that the encrypted member is no longer needed. If it is not, delete it from ACBLIB. If you are using a shared ACBLIB, all restarting data sharing IMS subsystems attempt cleanup, but only the first IMS to lock the ACBLIB finds the blocks to delete.
