I hate to be curt but I could easily write "yes, its crap" or "no, its brilliant"...but the fact is, the only person that will know if ASSM outperforms manual-SSM on *your* platform, *your* version is you.

It take only 10mins to produce some testing scripts and (say) 5 windows all running SQL Plus to get an idea of what you should be using. For example:

test 1: create small table (just a few blocks),'n' concurrent sessions inserting into it

test 2: create small table (just a few blocks),'n' concurrent sessions updating different rows in common blocks

test 3: delete, followed by insert test

etc etc

Easy to do, you can tailor them to your anticipated apps.

Bottom line - anything we post here may or may not be relevant to you.

Cheers
Connor
