ERROR DESCRIPTION:
IMS issues a macro interface to VSAM to invalidate a particular
buffer in the LSR buffer pool. If the buffer resides in a
hiperspace buffer, it is not invalidated and can lead to lost
updates if that address space later uses that downlevel copy
of the buffer. The external symptoms can be 'pointer checker'
errors, ABENU0852 and ABEND0849.
The problem only affects IMS applications using IRLM Notify that
have hiperspace buffers in the LSR pool. It does not affect
those IMS users of cross invalidate using the coupling facility.
IMS is the only user of this function. No other VSAM users are
affected.
ADDITIONAL SYMPTOMS:
ABEND0C4 in IDA019XV
msgDFS629I PSW AT ERROR = 077C2000 82D79960 SYS1
msgDFS629I MODID = UNKNOWN EPA = UNKNOWN SYS1
LOCAL FIX:
Remove hiperspace buffers from the LSR pool definition.
To do this, look in the IMS startup parms under DFSVSAMP DD or
the DFSVSMxx member.Remove any HSO,HSR, HSn subparms from
VSRBF= control statments.
