com.sap.aii.ib.core.ejbutil.rb_all.SERVER_MS_NOT_AVAILABLE Error on Integration Builder Login

As soon as you enter the credentials on ESR/Integration Repository/Integration Directory/Integration Builder, if you see the  error "com.sap.aii.ib.core.ejbutil.rb_all.SERVER_MS_NOT_AVAILABLE", it means that the message server could not connect to  the P4 port of the PI system

Call the following URL and check if P4 port is listed:
http://<msg_server_host>:<msg_server_port>/msgserver/text/logon

Try msg_server_port as the port 81NN, when NN is the instance number of ASCS or SCS or Central Instance (where ABAP message server and enqueue servers are running)

Depending on which message server lists the P4 port, maintain the message_server_port (81NN) in the following exchange profile parameters

  • com.sap.aii.connect.directory.mshttpport
  • com.sap.aii.connect.repository.mshttpport
If the error includes java.net.MalformedURLException, then the above profile parmaters are not maintained at all and must be maintained along with com.sap.aii.connect.repository.mshost and com.sap.aii.connect.directory.mshost
