I just checked my email... it wasn't and ENQ, it was a wait / hang. The
problem affects 9.0 and 12.0:
PRODUCT: CA-ACF2 MVS RELEASE: 12.0
APAR #: RO05222 DATE: 23 JAN 2009
PROBLEM DESCRIPTION: TA8580B: VSAM WAIT AFTER FORCE/CANCEL DURING I/O
---------------------------------------------------
STARTRAK PROBLEM: 8580
ABSTRACT: VSAM WAIT AFTER FORCE/CANCEL DURING I/O
DESCRIPTION:
IF AN ADDRESS SPACE TERMINATES DURING ACF2 VSAM PROCESSING
AND THE ESTAE DOES NOT GET CONTROL THE RPL WILL NOT GET
CLEANED UP. THE NEXT REQUEST WILL GRAB A 2ND RPL AND COULD
END UP IN A WAIT IN IBM VSAM MODULE IDA019SE ON RESOURCES HELD
BY THE 1ST RPL. CODE WILL BE ADDED TO REMOVE THE USE OF THE
2ND RPL. THIS WILL FORCE ONLY A SINGLE RPL TO BE USED. THE
ACF2 CODE WILL DETECT THAT THE RPL WAS STILL IN USE AND
INITIATE ACF2 VSAM ERROR RECOVERY WHICH WILL ALLOW VSAM TO
CLEAN UP ANY HELD RESOURCES.
