BusinessWorks, Windchill ESI, or both are failing to connect to EMS
This could happen if the EMS server is not configured properly. When you specify the name of the EMS server as localhost, that server is only recognized on the box that it is running on. No other machine can connect to it. An application that is set to localhost will attempt to find the EMS server running on the same machine. If it is not found, it will error. When you specify a machine name as your server name, other machines can connect to your EMS server.
To resolve this issue check that the QueueConnectionFactory value located in the <Tibco_Home>/ems/<version>/tibco/cfgmgmt/ems/data/factories.conf file and the global variable ESIJMS/JNDIContextURL in the deployment of the Process Engine are set accordingly.
• QueueConnectionFactory in factories.conf file = tcp://<machinename>:7222 Where machine name is the machine where the EMS server is running.
• Set the global variable ESIJMS/JNDIContextURL in BW Engine = tibjmsnaming://<machinename of where EMS server is running>:7222
It does not matter where this EMS server resides. It can reside on the same machine as Windchill PDMLink, same machine as the TIBCO process engine, or a different machine altogether. As long as the above values described are set appropriately (and the machines are on the same network), Windchill ESI and EAI components are able to connect to the correct EMS server.
To determine which machine and username is connected to an EMS server, type the following command in the TIBCO EMS administration tool:
>show connections
This gives you a list of which users are connected and from which machine.
