Error description
DB2DDF DB2LOB defect pm79540 dpm79540 There is Abend04e Rc00e2000c in DSNSVSVB Offset0AC2 when using DRDA Encryption because module of DFSLCMSL request a 964M ( x'3C449808') encryption buffer. ************************************************************ Additional Symptoms and Keywords: ABEND04E AB04E S004E 04E 04E-00E2000C 00E2000C RC00E2000C DSNLCMSL.DSNSVSVB+0AC2 DSNLCMSL DSNSVSVB +0AC2 Offset0AC2 CMGR64 BUFFER POOL 04E-00D31014 00D31014 RC00D31014 DSNLIRCA DSNLIRCA:0001 0001 VRADC0001 ABNDID0001
Local fix
Disable data encryption at the remote requester environment.
Problem summary
**************************************************************** * USERS AFFECTED: All Distributed Data Facility (DDF) users. * * Specifically those using LOBs or XML and * * DRDA encryption is enabled. * **************************************************************** * PROBLEM DESCRIPTION: ABND=04E-00E2000C * * LOC=DSNLCMSL.DSNSVSVB+0AC2 * **************************************************************** * RECOMMENDATION: * **************************************************************** DB2 server LOB processing incorrectly over allocated storage for a LOB when the remote requester requires DRDA encryption of the data. The reported abend occurred when an attempt was made to allocate encryption buffers since the pool already reached its limit. The pool may also have become highly fragmented due to requests to enlarge message buffers where a storage area of the larger requested size was not available.
Problem conclusion
DB2 server LOB processing has been changed to allocate the right amount of storage to hold a LOB based on its length, when using DRDA encryption. DB2 server processing will also periodically request the contraction of the storage pool used to obtain the storage for message buffers so that the impact of storage fragmentation will be minimized.
