Hello
Here is a typical AFM string you can see in the receiver.log file of the System Agent, where xxxxx is the name of the primary or shadow machine, depending on which one is taking the control over the system agent.
06/28/2017 03:04:28.878 EDT-0400 2 TCP/IP Controller Plugin.Receiver pool thread <Regular:1>.CybReceiverSession.accept[:276] - Message received: 20170628 03042886+0400 WA_AGENT ORA_APP_********* 8_27724_4136158928_1498633426_796968_CM/WAAE_WF0.1/MAIN CONTROL MGRADDR Port(7500) Address(xxxxxxx.ca.com) SocketFactoryId(plain) User(ORA_APP_******)
Here ORA is the instance name and ORA_APP means that the request comes from the Application Server of instance ORA
Therefore if the communication.manageraddress entry of the agentparm.txt file has not been updated by your shadow scheduler, I would suggest to check if you see such AFM in the receiver.log file and look for any error in the application server log.
A typical error could be that the shadow scheduler cannot resolve the node_name of the machine definition of the system agent or the AFM port is blocked by a firewall ( default receiving port in the agentparm.txt file is 7520 )
Check all of this with:
- ping <agent>
- telnet <agent> <7520>
Regards
Jean Paul
