i hope anybody can help me to understand the Privilege Delegation feature
one exambles (Unix OS (AIX))
My Listener and the database is running with user B on the OS . User B does not have OS login rights . We must login with user A and change to user B to manage the listener and the database .
In the EM12C the User A has the Run Privilege Sudo an run as user B listed .
When i shutdown the LISTENER with User A (run as B) the LISTENER goes down . When i startup the LISTENER with user A (run as B ) the LISTENER starts and the listener process run as user B . thats fine .
The same examble with the database ends with that that the database run as user A instead as user B
on the os i have the following entry in the sudoers file .
a ALL = NOPASSWD: /usr/bin/su - b, (b) /products/oracle/agent12g/sbin/nmosudo
