How to identify read only access to the database? At the end, I would like to separate those application module with SELECT privilege to run on a newly created read only service name.

1/ What do you mean by a read-only service name?
2/ Without tracing all sessions or auditing all statements you can't know which modules are read-only and which ones are read-write.

What do mean by
Quote:

Read-only service name created in cluster level.

Also, is this actually an Enterprise Manager question? Or should the topic to moved to another forum?

Read-only service name created in cluster level.

Yes. It is related Oracle enterprise manager question. Apologize for confusing here.
For example, we will see such service name running in cluster level.
e.g.:
$ srvctl status service -d dbname
Service app_read is not running.
Service app_readwrite is running on instance(s) dbname1,dbname2

I've moved your topic to the RAC forum, it has nothing to do with Enterprise Manager.

You seem to have created your service, all you need to do is start it:

srvctl start service -d dbname -s app_read

What's the problem?

And, just to do the moderator bit:

Can I use Oracle logminer to track the 'SELECT' transaction?

There is no SELECT transaction.
SELECT does not generate redo data so there is nothing LogMiner can see.

My database version is 11.2.0.3.0, 11.2.0.4.0 and 11.1.0.7.0
I think I could only use tracing sessions or enable audit in order to detect the select sessions running on database.

What will be gained by doing as above?

What will be done with any session that does both SELECT & DML (INSERT, UPDATE, or DELETE)?
