OEM - Agent fail to start after relocating databases to new server
We have 2 servers. Server A and Server B were valid targets under OEM with databases on each. OEM was working fine.
Version (kinda old, but works great):
Agent Version : 11.1.0.1.0
OMS Version : 11.1.0.1.0
Protocol Version : 11.1.0.0.0
Since Server B is newer, we have moved our databases from Server A to Server B. We can connect, etc to the newly-relocated databases at the new home on Server B using SQL*Plus, etc.
We shut down Server A; Server B was reconfigured to same name/IP as old Server A.
All previous databases on Server B are gone.
In OEM, I dropped all targets on this host and then the agent. To add host, OEM said "restart agent on database server".
