Hello: I have some questions: 1. We have a java tool that makes queries to the Databas (9.2.0.6). When I check in the v$sql view at 5pm I can see there are entries since 8:30 in the morning, with 0 executions and other fields, I guess they=B4re invalidated or just old, but when would the dissapear? Ther is a way to get rid of that entries. 2. Oracle says that V$sqlarea is an aggregate of V$sql but when I do a sum of the sharable_mem of the active entries of a hash_value the result is different of the sharable_mem of the V$sqlarea. I will appreciate your ideas. --=20 Alfonso Leon -- //www.freelists.org/webpage/oracle-l
