understanding /etc/group and how it links to a db access


when user prvilege specification includes
DBA ALL =(ALL) ALL

Does this mean users under the DBA group automatically have database administator privileges?

Need to understand if users assigned to DBA group in LINUX can access DB (Oracle) in this case as administrator.

That looks much more like the format for the sudo users file, at first glance (my /etc/group file has -nothing- akin to that).

Similarly, at least in MySQL, individual users' permissions are stored within the database themselves, and have absolutely no bearing on shell users or their permissions.

I highly doubt the Oracle database (or any db system for that matter) relies on the local filesystem user permissions for authentication in regard to access to specific databases. I am sure there are more Oracle-savvy folk around these parts who can chime in, but as I said, I greatly doubt that the groups file has anything to do with database permission./

Hi,

where did you retrieve this permissions from? From my point of view it does not show anything about filesystem or Oracle application permissions. Where did you find that in what file?

the permissions were shown in etc/group.

from what I read in other sources, there is a possiblity that linux admins can directly access oracle with osdba or dba permission in linux.

Can you perhaps post those sources or the relevant information therefrom? It would go a long way to help others help you.
