RE: object names in 10046 trace

Brandon,

On systems I've seen lately where the object name shows up in the row source operation name, I've been able to see evidence of additional recursive SQL statements executed in the database to obtain the object name using the object id. In some cases, I've even seen the PARSE, EXEC, and FETCH calls interspersed among the STAT lines for a single cursor slot id.

Subject: object names in 10046 trace

Anyone know why sometimes a 10046 trace records object ID numbers and other times it records the object name? Below is an example of both for the same query in the same trace file (parsed in two different cursors) on Oracle 9.2.0.5 running on AIX 5.2:

STAT #22 id=21 cnt=27 pid=4 pos=2 obj=7511 op='TABLE ACCESS BY INDEX ROWID TTDSLS041210 '
STAT #22 id=22 cnt=27 pid=21 pos=1 obj=9756 op='INDEX UNIQUE SCAN TTDSLS041210$IDX1 '
STAT #22 id=23 cnt=0 pid=2 pos=2 obj=7511 op='TABLE ACCESS BY INDEX ROWID TTDSLS041210 '
STAT #22 id=24 cnt=0 pid=23 pos=1 obj=9756 op='INDEX RANGE SCAN TTDSLS041210$IDX1 ' STAT #37 id=21 cnt=0 pid=4 pos=2 obj=7511 op='TABLE ACCESS BY INDEX ROWID OBJ#(7511) '
STAT #37 id=22 cnt=0 pid=21 pos=1 obj=9756 op='INDEX UNIQUE SCAN OBJ#(9756) '
STAT #37 id=23 cnt=0 pid=2 pos=2 obj=7511 op='TABLE ACCESS BY INDEX ROWID OBJ#(7511) '
STAT #37 id=24 cnt=0 pid=23 pos=1 obj=9756 op='INDEX RANGE SCAN OBJ#(9756) ' I tried to find the answer on Metalink and Google, but no luck.

Thanks,
Brandon
