Rich,

I have a better set of steps for you:

1).  Create a new tablespace (TEMPLMT) and make it a LMT.
2).  One by one, issue ALTER USER {username} TEMPORARY TABLESPACE TEMPLMT;
3).  Bounce the database
4).  DROP TABLESPACE TEMP INCLUDING CONTENTS;
5).  Backup the database
6).  Let users at it.
7).  Go have a beer.

The only "negative" here is that your TEMP tablespace is called TEMPLMT, but it just doesn't matter. If you want, you can do it again, this time creating the tablespace as TEMP if it makes you feel better.

Your method would work just fine. Not sure if the users would lose the designation of their TEMPORARY TABLESPACE, but if they do, you can easily create a script to set their temp tablespace to TEMP again.

Hope this helps.

Hey all,

I've got some downtime coming up on an 8.1.6 DB on Solaris, and I'd like to take the opportunity to convert the datafiles of the TEMP tablespace to tempfiles. My reason for this change is primarily to get the TEMP tablespace LMT, but also to shrink our hotbacks w/o modifying the working script.

I've been trying to reason out this task in my head, as I can't find much on MetaLink, and here's what I've got so far:

Shutdown DB.
Backup DB.
Startup restricted.
Offline tablespace TEMP.
Drop tablespace TEMP.
Create new temporary TEMP LMT.
Bounce instance.

I don't yet have an arena to try this in. Will users whose assigned TEMPORARY TABLESPACE is TEMP need to be ALTERed? Anyone have any comments on the procedure?

TIA! Rich
