Home -> Community -> Mailing Lists -> Oracle-L -> RE: LMT's and DMT's in same database?
Dave
No particular strategy, other than using uniform extents. Using the Oracle guidelines, I created a tablespace with 128-k extents for small tables and one with 4-m extents for medium tables, with matching index tablespaces. Then I started moving tables to these tablespaces and rebuilding indexes to the index tablespaces. The large tables I've put in their own tablespaces, again following guidelines. My largest database is about 150-gig. total. As I've created or moved tables, I've stuck with this. I haven't yet moved some of the more static tables yet. I subscribe to the Lazy DBA theory that the more energy you put into certain activities, the more likely you will cause your own problems. Otherwise known as "if it ain't broke, don't fix it." And when I've created 9iR2 databases, I've let Oracle create everything as LMT and used automatic undo. But not too much usage there yet, so I can't guarantee no problems there yet.

Dennis,
I also am working towards converting my databases to LMT's. Do you have a doc/link on how you are doing this?
Thanks,
Dave

Dave - This shouldn't be a problem. I am gradually converting my tablespaces to LMT, but for relatively static tablespaces, I haven't had a reason to go in and rebuild yet. Yes, I know there is a procedure to convert a dictionary-managed to LMT, but I don't trust it.

I am going to start playing with Locally Managed Tablespaces in an existing database that has Dictionary Managed Tablespaces. Can I have both of these two tablespace types in the same database?
Thanks,
Dave
