Symptoms

An ORA-600 [kkdlcob-objn-exists] error is reported in the alert log file, e.g.:

ORA-00600: internal error code, arguments: [kkdlcob-objn-exists], [4255107218], [], [], [], [], [], [], [], [], [], []


Sometimes the ORA-600 [kkdlcob-objn-exists] error may be seen together with an ORA-600 [ktcpoptx:!cmt top lvl] error, e.g.:

ORA-00600: internal error code, arguments: [ktcpoptx:!cmt top lvl], [], [], [], [], [], [], [], [], [], [], []

The call stack in the generated trace file (for ORA-600 [kkdlcob-objn-exists]) looks similar to:

... kkdlcob ctcdrv opiexe opiosq0 opiall0 opikpr opiodr rpidrus skgmstack rpidru rpiswu2 kprball qks3tCreateTT_RC qks3tCrtTmpTabl qkswc3Tmain qkswcDriver apadrv opitca ...

where function qks3tCrtTmpTabl is typical for this problem.

The current SQL looks similar to:

CREATE GLOBAL TEMPORARY TABLE "SYS"."SYS_TEMP_0FD9FC892_45659C4D" ("C0" NUMBER,"C1" NUMBER,"C2" VARCHAR2(13),"C3" NUMBER,"C4" TIMESTAMP(3) ) IN_MEMORY_METADATA CURSOR_SPECIFIC_SEGMENT STORAGE (OBJNO 4255107218 ) NOPARALLEL
