Re: Convert TEMP tablespace from datafiles to tempfiles

Rich,

If you've got the disk space, do it while the DB is up. Much simpler.

Create a new Temporary LMT - call it NewTemp - with the appropriate tempfiles.

Switch everyone to NewTemp by spooling and executing this and running the spooled file:
Select 'Alter User ' || UserName || ' Temporary Tablespace NewTemp ;'
>From DBA_Users;

After a day or two, or when you can determine that no one is using the old Temp tablespace, offline and drop Temp.

If you've just got to have the Temp tablespace named Temp, repeat the above steps to create a new Temp LMT.

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:

1. Shutdown DB.
2. Backup DB.
3. Startup restricted.
4. Offline tablespace TEMP.
5. Drop tablespace TEMP.
6. Create new temporary TEMP LMT.
7. 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
