Home -> Community -> Mailing Lists -> Oracle-L -> RE: extremely long parse time
Hmmm...anything SYS in DBA_TAB_COL_STATISTICS or DBA_ANALYZE_OBJECTS?
Is the COST column in your PLAN_TABLE null???

To: Multiple recipients of list ORACLE-L
We are using First_rows for the optimizer mode,
but the last_analyzed column in DBA_TABLES and
DBA_INDEXES is NULL for all objects owned by SYS.
The really wierd part is: Changing the query
to use rule based optimization (via the /*+ RULE */ hint
caused it to execute sub-second.
Why would optimization mode affect parsing? Is query
optimization considered part of the parsing routine?
