Problem summary
**************************************************************** * USERS AFFECTED: OMEGAMON XE for DB2 PE/DB2PM * * users of component * * - Classic Interface * * - OMEGAMON collector * **************************************************************** * PROBLEM DESCRIPTION: 1. ABEND0D5 RC21 in LMOD KO2OCNTB * * CSECT=O2ORCV, OFFSET=001704 * * 2. ABEND0E0 RC28 in OMPEIIO * **************************************************************** * RECOMMENDATION: Apply this PTF. * **************************************************************** PROBLEM SUMMARY: 1. During RETRY recovery for an expected ABEND0C4 in O2XTH2, an ABEND0D5-21 occurred in O2ORCV after a DB2 allied address space was swapped out. This occurred because another task in the allied address space issued a SYSEVENT TRANSWAP right after the initial ABEND0C4. 2. While navigating control blocks in AR mode, OMPEIIO took an error path that did not return to primary mode. This resulted in an ABEND0E0-28 on exit due to residual data in Access Register 15 (AR15). PROBLEM CONCLUSION: 1. O2ORCV has been changed to avoid the ABEND0D5-21 when the DB2 allied address space has been swapped out. 2. OMPEIIO has been changed to return to primary mode before exiting when taking the failing code path. KEYWORDS: ABEND0D5 S0D5 RC21 O2ORCV ABEND0E0 S0E0 RC28 OMPEIIO
Problem conclusion
1. O2ORCV has been changed to avoid the ABEND0D5-21 when the DB2 allied address space has been swapped out. 2. OMPEIIO has been changed to return to primary mode before exiting when taking the failing code path.
