Jeff, Has this product been reliable for you to use without doing anything funny to the database?

This is an oracle database where they bought the software and had the system admin install the software which included the vendors instruction of creating and setting up the database (basically use the defaults). It is an Oracle 8.1.7 database on Windows 2000. He wants me to find out "if you can create some indexes or something", etc. (he likes to give solutions before the cause if discovered). Anyway, I decide to take a look at it. The performance they are complaining about is when they log into the application it takes about a minute for their initial screen (which includes a list of values) to appear. I use the tool that someone posted here a while ago, SQL Monitor from www.fastalgo.com, and find that during the time the user is waiting for the first screen the application is executing a sql statement about 2200 times. The SQL is: SELECT PARENTID FROM PROC_ WHERE PROCEDUREID=:1 The bind variable is different for each execution with appears to be the procedureid values from the table proc_. Table proc_ has 2203 rows. I check the executions for the sql text in v$sqlarea. Executions = 58,825. (aha, I think this is the problem). I explain plan the query and find that it is using the primary key index. My tuning skills are still pretty basic. Since I have no control over the application is there anything I can do to increase the performance of running the query thousands of times? Also how do you usually deal with 3rd party application issues like this? 95% of our databases/applications are from 3rd party vendors and it's a pain trying to get them performing better.
