Chris,

I've always used a permanent tablespace for temp and have not had the problems you state. But it does take some consistency to maintain.

1- we never allow anyone a quota on temp or even allow anyone to have that as their default. Come to think of it only sys has system as it's default tablespace. We also do not allow 'unlimited tablespace' even to purchased apps. 2- The ST enqueue has not been a problem, actually have 0 contention there even in the data warehouse.
3- we don't back it up. Have had one get trashed, along with the disk drive. Did an offline drop and rebuilt it elsewhere.

No, it is generally better practice to use temporary tablespace for the following reasons.

You will not accidentently store objects in it.
Reduced contention for the ST enqueue
Reduce backup and recovery time

Oracle recommends creation of separate temporary tablespace for sort operations.
Is there any advantage in using a permanent tablespace instead of a temporary for sort operations?
