How does Oraclecloudcontrol12c modify the sysman password?

Oracle Cloud Control 12c was deployed on a virtual machine a few days ago, and the login password was forgotten. The main reason is that Oracle-related Software provides stronger security mechanisms than before. Simple pwd such as "oracle" is no longer supported. I just forgot about it for a while. In this year, there were many accounts and passwords, that is, there were not many meters. Haha... Let's talk about the solution.

Successfully changed repository password.

3. Stop the Admin server on the primary OMS machine and re-start all the OMS:

NOTE: 1511014.1-12c: After changing the SYSMAN password directly into the DB, OMS status shows "Connection to the repository failed. Verify that the repository connection information provided is correct"
