Error description
When an AGENT and LOGGED on USER tried to obtain DDF data concurrently, ABENDDC2 RSN0055 IARV64 SHAREMEMOBJ KO2CDFSA+90C R15 = 71005520. From the OMPE STC log: KO2I0170U SDC2 ABEND IN MODULE ........ PERCOLATED TO D5API MODULE KO2ACONB IEA794I SVC DUMP HAS CAPTURED: DUMPID=004 REQUESTED BY JOB (OMDB2OD1) DUMP TITLE=OMEGAMON II FOR DB2 DUMP: TASK=COMMCOLL,ID=V410 ,MOD=UNKNOWN ,OFFSET= ,CODE=SDC2/71005520 KO2I0157I D5API COLLECTOR DISCONNECTED FROM DB2 DT11 AS REQUESTED BY AGENT OMDB2XD1 KO2I0154I D5API COLLECTOR CONNECTED TO DB2 DT11 ON BEHALF OF AGENT OMDB2XD1 ABENDDC2 rsn71005520 (xx0055xx) because a duplicate UToken already exists for the memory object specified for the address space. SYSTRACE shows the following: 0077E3D0 PC ... 7 00_41714141 0090E IarV64 0077E3D0 SSRV 14B 0A804001 00000DC2 71005520 IarV64 ShareMemObj 00000000_4623CEB8 00000300_A0104580 0000000F_D9D8C140 <-- UToken 0077E3D0 *SVC D 070C5000 818E07F0 71005520 84000000 84DC2000 ... with the address 41714140 pointing to KO2CDFSA+90C (at PK80926 level). A few SYSTRACE entries earlier, the TCB at 007B7118 issued 007B7118 PC ... 7 00_41714141 0090E IarV64 007B7118 SSRV 14B 0A804001 00000000 00000000 IarV64 ShareMemObj 00000000_44FFC4D0 00000300_A0104580 0000000F_D9D8C140 <-- UToken At the time that the SVC DUMP was generated, TCB 007B7118 had yet to issue an IarV64 Detach, meaning the USERTKN of 0000000F_D9D8C140 was still in use. When KO2CDFSA issued the IARV64 REQUEST=SHAREMEMOBJ, USERTKN=USRTKNS, ... it did not check for USERTKN being unique. . Additional symptom: An SVC dump occurred with this dump title: Dump Title: OMEGAMON II FOR DB2: COMPID=5655OPE00, JOB=CANSO2 , LMOD=KO2CDB2A#L, CSECT=#UNKNOWN, OFFSET=012C3E ABEND0C4 rc3B occurred in KO2CDFSA+C1E (at R420 PK87445 level) on a CLC instruction with DPSBRQAP RQA pointer above the bar.
