EM 13c: How to Change Monitoring Credentials For WebLogic Domain Target

We changed WebLogic user password for enforcing security principal, then WebLogic domain targets show down on OEM. Hence we need update the monitoring credentials on OEM for WebLogic domain.

1) Verify the correct Admin Server hostname and password are correct:

EM Console > Middleware Targets > click the WebLogic Domain > WebLogic Domain dropdown menu > choose WebLogic Server Administration Console

Log in with this username/password

and note the Administration Server hostname as indicated in
- the url at the top of the page > https://<AdminServerFQDN>:<port>/console/...
and/or
- under Servers > AdminServer(admin) > Machine column shows Administration Server hostname 

This step is necessary only if this WebLogic Domain is monitored by multiple agents:
2) Put the WebLogic Domain target under blackout:
Monitoring > Blackouts > Create… > > choose “Blackout” (Create)
Choose “Enable Full blackout…”
Add the WebLogic Domain target (select)

3) Modify the password for the WebLogic Server Administr Server using the hostname and password verified in step 1

There are 2 possible ways to navigate to the Monitoring Credentials in EM:

  • Setup (top right) > Security > Monitoring credentials > choose Oracle WebLogic Domain and click “Manage Monitoring Credentials” > choose the Domain and “Set Credentials”
    The is Domain and Node Manager credentials are set in separate places here
    Test and Save configuration

or

  • From the WebLogic Domain’s Home Page > under WebLogic Domain dropdown men > choose Target setup > Monitoring Credentials
    Both the Domain and Node Manager credentials are set on the same page
    Test and Save configuration

This step is necessary only if step 2 was implemented:
4) If Blackout has not already expired,

Monitoring > Blackouts > View by Blackout Name > choose blackout and “Stop”

5) Refresh WebLogic domain.
From WebLogic Domain home page > WebLogic Domain dropdown > choose “Refresh WebLogic Domain”
