To answer CHALAVADI question: I think we do have fetches across commits. But I'm not sure how to verify that. The application was written in C/C++ and I'm not familiar with C/C++.

To answer julian's question: Each rbs currently has 3 min extents and max extents unlimited.

The dba keeps changing the rbs's. Current settings are:
7 rbs, 3 min extents, 30 meg initial & next, Optimal 90 meg.

Hope this helps.

Thanks.
