Symptoms
In Applications Manager only one client session can be opened to the same Master on the same machine by default.  If an attempt is made to try and open more than one client session, you will receive the above error.

---

Cause
With TCP/IP you cannot have 2 sockets connected with the same parameters. Therefore, if you have a firewall installed and have the ClientRMIPortNumber (defined in the Options.properties file) locked down to a single port only one client session is allowed.

---

 

Environment

Release: AAMOS499000-8.0-Automic Applications Manager-OS400 Agent
Component:

Resolution

If the RmiServer is behind a firewall only the RMIRegistryPortNumber and the RMIDataPortNumber (specified in the Options.properties file) need to be open in the RmiServer's firewall (defaults to 1099). 

Remove the ClientRMIPortNumber from the Options.properties file, if it exists, or set it to 0 to allow more than one client session to be opened.
