List,
Would you please explain to me how you are able to get TEMP and LMT combined together. I use 8.1.7 and it is not allowed. "Oracle8i DBA Handbook" Loney and Theriault, Osborne Oracle Press, Page 598 NOTE
"If you specify Local in a create tablespace command, you can not specify a default storage clause, minextents, or temporary. If you use the create temporary tablespace command to create the tablespace, you can specify extent_management local."
The tablespace that is being created is a tablespace with type = temporary not permanent? correct?

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
