Hi Hemant,
Thanks for replying.We are not using any hints as we have decided against them after checking their pros and cons.There are no triggers on any of these tables.No this behavior is reported recently after the upgrade of Database. Strange thing is that all other instances arerunning fine except this. RegardsAbhishek

Do have LOGGING / NOLOGGING differently configured in the two reference environments ? What about APPEND Hint and/or PARALLEL configurations ? Are there ON INSERT triggers on the table ? What does AWR show about load on the database and wait times ? Has this been the behaviour since day 1 or is it of recent origin ? Can you associate it with any recent changes to the database ?

Subject: Performance problem: Loading data via insert Hi

We are facing a performance problem but unable to identify where is the problem.

We have a production database server where about 8 database instances of oracle is running. Daily we insert in each of these database instances about 1-5 GB of data in different tables. All database instances are working fine where we are able to load around 2-3 GB of data within 1hour except 1 where it is taking about 8 hrs to load only 4 GB of data.

When I try to load the same 4GB of data in another database where only one instance is running and with very less configuration as compared to the Production server we were able to load it in 1hr 45 minutes.

Can anyone suggest how can we proceed to identify the problem?
