Hi,
We have two different types of DBA group in current on-premise Oracle
databases, one who deploy code in prod and highest level of privileges
(i.e having write access to the database objects, performing backup
recovery, export/import and performing other database maintenance jobs etc).
and other groups, who only have read only privileges (select catalogue
role i.e access to data dictionary views, run time and historical
performance views along) mainly look into the performance issues and
more alligns towards the functional part of the application ,
understands the database design working closely with Application
Development team and they have read only access to the databases. They
are expert in reading query execution path and have privilege to run the
explain command, reading sqlmonitor report, creating profiles, baselines
, adding hints to the query by understanding inefficient execution path,
fetching AWR report, tracing sql queries, gathering object statistics,
accessing OEM(oracle enterprise manager ) to monitor performance.
Suggesting appropriate indexes and partitioning strategies for tables etc.
Now that we are moving few of the applications to Postgres on-premise
database and few to aws RDS postgres. What kind of privileges should we
provide to these two groups? Mainly we don't want the performance guys
to have the elevated privileges. I can understand , readonly access to
the table is something we can give to those users. Apart from that, are
there any specific privileges which we should provide, so as to enable
look and debug into all types of performance issues without any
obstruction and at the same time not giving elevated privileges?
