Creating onetime EM agent Registration Password in 12C & OMS Unreachable issue fixed

Creating a onetime agent Registration password & OMS Unreachable issue fixed

While working on the issue with the agent in one of the Linux box. it prompts for the Agent Password which i don't have. As i couldn't get the password from my inventory list, I have created instant agent one time registration password.

The below are the steps i followed.

Login to the OEM 12C with sysasm credentials

Setup à Registration Passwords. This will direct you for the security page.

Select <Initial Agent Registration Password> and click on the Add Registration Password window.

In the Add Registration Password page, enter the password and select the one-time password button and set the expire Date.

Now my one time Agent Registration password has been set.

Then, i logged into the Linux box where EM Agent was not able to communicate with OMS Server and Heartbeat status: OMS Unreachable.

The below are the commands and output copied as it is from the server

cpliadea:/u01/app/oracle/product/agent12c/agent_inst/bin> ./emctl pingOMS
