Rollback per transaction

edited Apr 28, 2010 1:48AM in Database Tuning (MOSC) 9 commentsAnswered
 This is for oracle version 10.2.0.3 and os platform solaris sparc 64 bit in solaris 10 version.

I ran the statspack on test server and the dev server. The for the test server the rollback per transaction in the report shows 0.00%. But for the dev server, it shows 14.15%. This seems a little high I think. How can I find out why there is rollbacks in the application? How should I approach to improve this and make the percent lower?

The only difference between test and dev server is that test server used automate SGA and dev server manually sets SGA. Thanks.

Howdy, Stranger!
