Problem summary
**************************************************************** * USERS AFFECTED: All Distributed Data Facility (DDF) users. * * DB2 10 for z/OS only. * **************************************************************** * PROBLEM DESCRIPTION: Various 04E-00E2000C abends may occur * * after installing APAR PM64376 (PTF * * UK83114). * * Symptoms may include: * * o 04E-00E2000C,DSNLILNR.DSNSVSVB+0AC2 * * o 04E-00E2000C,DSNLTACC.DSNSVSVB+0AC2 * * o 04E-00E2000C,DSNLIRTR.DSNSVSVB+0AC2 * **************************************************************** * RECOMMENDATION: * **************************************************************** When remote client applications connect to a DB2 10 for z/OS server via TCP/IP, System Profile Monitoring (SPM) support in DB2 10 for z/OS monitors events related to the different remote client applications that access DB2, even if SPM is not enabled. The storage utilization accumulates over time due to processing and monitoring the remote applications. The changes provided by PM64376 address a storage accumulation issue by allowing DB2 to reuse available DB2 (SPME) control blocks when they no longer reflect active usage. However when reusing the SPME control blocks, a separate control block, that stores the information about the remote application, is not freed. Over time, this can eventually lead to the reported symptoms. This problem only occurs after the installation of APAR PM64376 (PTF UK83114). The entire DB2 subsystem must be stopped and restarted to relieve the storage condition.
Problem conclusion
DB2 10 for z/OS server processing has been changed to free the control block that is no longer needed.
Temporary fix
