Re: Seeking opinions

Um...

It depends on whether those whining staff DBAs are managing a failover environment. If you created that datafile on a file-system in a "non-failover" (not "failover-enabled") volume group, especially when rollback segments are involved, then you've just ensured an un-open-able and un-recoverable database in the event failover should occur.

Congratulations! It's not everyone who can do that so easily!

If you haven't considered that, then I have to question why you have the permission to ALTER TABLESPACE. Don't assume that you know everybody's motivations...

There. I feel even better... :-)
