Hi, You just recently experienced a performance issue with queries accessing a particular table. Response time went from 15-20 seconds, to 2-3 minutes.The table has around 500,000 rows, and is a "core" table in the app. I did run 1 problem query interactively to get the explain plan. The query did a table lookup via an index, and it returned 165 rows. The "consistent gets" though were around 1 million. This is a 3rd party app, so what we can do with the query itself is limited. The temporary workaround was to cache the table. This brought the response time back to normal. By caching the table, I assume the table will be handled differently in cache.The better results show that. But why did the query behavior worsen ? I am trying to track down the root cause. Any ideas are welcome. thanks ed solaris 10 oracle 10.2.0.4 - 2 node cluster- asm 10.2.0.4 clusterware 10.2.0.4
