There is no major differences in your opinions/ideas here. Just think about it as enforcing a naming conventions.
It's nice to have but hopefully it will last when one mount point gets filled or slow and some files need to be created/moved somewhere else violating the defined standards.

So come with a standard that is doable short/long term.

Waleed

Hi everyone.

I'm currently working at a client where the OFA standard has been (as they put it) "taken to the next level". I disagree with their approach, and I'd be interested to see what list members think.

The client believes that any DBA (there are about 16 on staff) should be able to locate data files in any database without querying the data. To this end, mount points are named both /unnn (e.g., /u001) and /annn (e.g., /a001). "System" datafiles (system, temp, rollback tablespaces) go only on the /unnn mount points, and in particular, datafiles for certain tablespaces must go on certain mount points--for instance rollback tablespace files always go on /u004.

"User" datafiles are allowed on /a001 and /a002, tables and indexes, respectively.

To my mind, this standard changes the Optimal Flexible Architecture to the Sub-optimal Inflexible Architecture, and all just to avoid a data dictionary query. What do you think?

Thanks,
