While issuing a grant statement, an ORA-600 error was generated.
ksedmp: internal or fatal error
ORA-00600: internal error code, arguments: , [kqdobu], [U], , ,[GL_POSTING_INTERIM_21597], , 
The trace file shows the failing statement:
GRANT ALL ON "GL_POSTING_INTERIM_21597" TO APPS WITH GRANT OPTION
Please note that the object name is unique to this case, and yours may be different (ORA-00600: , [kqdobu], [U], , [xx],[<object name>], , ) .
The function stack may look like the following:
The main functions of concern are: kqdobu <- kqrcmt which are trying to update internal tables.
Looking through the trace file for the object name, you may notice other cursors that indicate that the object was dropped.
Checking the recyclebin, we can confirm that the object was dropped and the time of the drop (in this caseGL_POSTING_INTERIM_21597)
WHERE ORIGINAL_NAME = 'GL_POSTING_INTERIM_21597';
ORIGINAL_NAME OPERATION TYPE DROPTIME
------------- ---------- ------ ----------
GL_POSTING_INTERIM_21597 DROP TABLE 2009-03-03:09:22:24
If you match up the timestamp of the DROP, it will be the same as the
timestamp on the failed GRANT statement.
