RE: Optimizer Mode......how to choose the right one?

You probably already thought of this, but I hope you aren't analyzing the SYS schema? This can cause terrible performance problems.

I tried FIRST_ROWS, analyzing the tables, but users claimed that performance was getting worse, so I chaged it to Choose. Always analyzing the tables....

but, everytime I analyze the tables, performance gets worse. Is this a normal behavior?

Any advice will be welcome!

thanks is advance,
