Darren - Do you have to reorganize the vendor's files now? The objective of LMT's is to make Oracle more self-managing (you know, so the MS SQL people can't say it takes a lot more DBA time to manage the database). To me in your situation, the bottom line is whether you have to spend quite a bit of time reorganizing those files today. If the answer is "no", then LMT's probably aren't going to help you much. If the answer is "yes", then that gives you some opportunity try something with their files, since you are doing that anyway. The key point is whether you know how the vendor's software interfaces with Oracle. If you have to reorg quite a bit, then I am confident you know that interface well (otherwise you are jeopardizing the data). If the vendor has made it pretty automated (management of the data), then you probably aren't that familiar with the details of how the vendor accomplishes that, and shouldn't mess with their stuff. I apologize for being wordy here, but maybe you can see my point. Dennis Williams

I am looking into locally managed tablespaces, have done some research, and have a basic
understanding of how they work, but I am unsure about the benefits if any for my environment.

I have multiple instances running, one for each application. In some cases these apps just have two tablespaces, data and index.

If I have a tablespace that is composed of tables that are various sizes and activity, will LMT help or hinder ?

I have read the paper about creating tablespaces based on extent size, which is the concept
I would follow, but I am unsure how the vendor(s) would feel if I re-org'd their database(s).

Thanks

Darren
