VSAM RLS deadlock and timeout problems z/OS DFSMSdfp Diagnosis SC23-6863-00 |
|
Deadlock or timeout errors in SMSVSAM will cause CICS® to issue messages DFHFC0164, DFHFC0165, DFHFC0166, and DFHFC0167. They should provide enough information to determine the cause of the problem. If additional information is needed, the CICS FC level 2 trace will provide the VPDI (mapped by IFGVPDI). The VPDI is the source of the information provided in messages DFHFC0164, DFHFC0165, DFHFC0166, and DFHFC0167. The SMSVSAM trace OPTIONS=DLKPD can be used to trace the VPDI. Note: The information returned in the VPDI can be out of
date. There is a lag between the time the problems are detected and
the request fails. For a timeout, information on the blocking holder
might not be returned because that request completed before the information
could be extracted.
