Do users need access to UDUMP, CDUMP and BDUMP?

Experts,

          Do OS users need access to ORacle UDUMP, CDUMP and BDUMP files? If users only have READ persmissions then is this a security issue?

the only account that "needs" access is the oracle account itself.  If you give it to the entire dba group and other admins, that's fine too.  

As long as oracle itself can write to the files, the db will run just fine

it can be a security issue, however, the files in those directories can be absolutely necessary for debugging purposes and/or tuning.

You can block access to them, but if you do that, then you'll have to have somebody available to retrieve the files for the blocked users when they are needed.

sdstuber is right, normally you don't allow users to access the default directory for security reasons. What you can do is create a script to move certain files to a separate server or allow users to change the directory via a stored proc.

Here is a Tom's example:

It's more like the DBAs and the dump-file owners need access; others do not.

Is tracing information the only info. collected in the dump files?

memory dumps and status info will be written for errors

So is it safe to assume that removing Users OS account (READ) completly from the dump files and only allowing Admin, System and dba's will not break the db functionality?  I know for some files, the USER account must have a least READ or an error will occur.
