(Doc ID 338322.1)
Last updated on MAY 19, 2021
Applies to:Oracle Database - Enterprise Edition - Version 126.96.36.199 to 188.8.131.52 [Release 9.2]
Information in this document applies to any platform.
The following error/combination of errors have been observed within the alert log for this issue:-
a) ORA-00600+ORA-07445[LXMCPEN] within the same trace file
b) ORA-00600+ORA-07445 within the same trace file and in 7445 file we see LXMCPEN within the stack
a) Both 7445/600 errors will be seen in a single trace file and maybe in addition in separate files but at least one trace file should contain both errors
b) The 600 trace will contain a message similar to :-
EXTENT 4 addr=1039b8708
Chunk 1039b8718 sz= 600 recreate "bind var heap " latch=0
ERROR, BAD FIRST EXTENT (0)
And the Chunk needs to be "bind var heap" when the bad extent is reported
c) The session info will show that a DBLINK is being used
If other symptoms are seen this should be considered as a different issue
