Granting Access To Non-DBA Users to the Oracle Enterprise Manager 11g Grid Control Performance Tab
Normally users who do not have DBA roles can not access Oracle 11g Performance related information using OEM 11g Grid Control.
Normally only Oracle 11g DBAs are allowed to view these tabs and they use them to do performance tuning or to identify problematic SQL or session etc.
However there is a way to grant access to OEM 11g Grid Control performance tab to users who do not have DBA roles. In this case the user means the users in the target database. This is helpful when you as a Oracle 11g DBA wants to grant access to the performance tab to management users who would like to have access to these data.
This is done by assigning OEM_MONITOR role to those users.
Caution: Please not that OEM_MONITOR role comes with a number of powerful privileges. So really give a thought if you need to assign OEM_MONITOR to not so technical users.
A way to avoid that is to create another role and assign OEM_MONITOR role like privileges to that role.
Here is a list of the privileges that OEM_MONITOR role has in Oracle 11g database:
SQL> select ROLE, TABLE_NAME, PRIVILEGE from ROLE_TAB_PRIVS where ROLE=’OEM_MONITOR’ order by 3,2;
ROLE TABLE_NAME PRIVILEGE

Oracle Forum List: List of Oracle technology related forums
Oracle Forum List: List of Oracle technology related forums
Often I find myself seeking help in Google for my Oracle technology related work. Be it developing new functionality at my workplace, looking for solutions to problems that I don’t know about or simply looking for more information on some particular topic I find oracle forums of great help.
In fact I have found senior Oracle technology guys who works for Oracle also use Google to find solutions when they are in customer sites. I am sure if they go through proper channel they have enough expert to these to provide a solution to issues. But that means a lot of time in SRs and involves a lot of team work and administrative overhead. I don’t think seeking information on internet is wrong as long as the job is done.
After all Internet is to share information and there are tons of information on the internet to help everybody. To my view any Oracle developers, Administrators (DBA), Designers or Architect should actively go to internet to find ideas to how to enhance a solution or simply finding new ideas.
In my experienced I keep forgetting which Oracle forum I have been looking for while looking for information.
So Here I have created a list of forums which you can use for your own good. Of course from now on this list of oracle forums will also help me to keep a note of which forums I frequently visit.
List of Oracle Forums:

It is also very nice if you can help out others by answering questions to which you may know the correct answer.
However do keep in mind that posting answers to old questions is not a very good idea. As the person who may be asking the questions may have found the answer long time ago or simply abandoned to look for the answer in that forum.
Also while looking for answer or solution; it is good idea to put as much information as possible so that others may know your issue in details so that they can provide better solution to your particular needs.
I have found forum posting a great place to find answers quickly. They are usually frequented by very high calibre people who may be able to help you out within minutes.
This list of Oracle forums should be enough to start. The list is in no particular order.
If you find any good oracle forum please share it here by sending me as a comment so that I can add that in the list my mine and others reference.
