One of the main issues we all have faced when working on a TIBCO BW and EMS integration is the reconnection part. Even though this is something that we need on minimal occasions because of the TIBCO EMS server’s extreme reliability, it can have severe consequences if we don’t have that well configured.

But before we start talking about the options, we need to do a little background explanation to understand the situation entirely.

Usually, there are two ways that we can use to connect our TIBCO BW application to our TIBCO EMS server: Direct and JNDI. And based on that, this will change how and where we need to configure our reconnection properties.

TIBCO BW + EMS: Direct Connection

This is, as it sounds, a direct connection to the TIBCO BW application to the EMS server itself, with the listener used to send and receive messages. There is no component in the middle, and you can detect that because on the JMS Connection Resources, it will show as “Direct,” and the URL is always in the following fashion: tcp://server: port as you can see in the picture below:

TIBCO BW + EMS: JNDI Connection

This is a different kind of connection, and it has a central component compared with the Direct link, as you can imagine. In this scenario, at the connection time, the TIBCO BW application performs a first connection to the JNDI server that is inside the TIBCO EMS server and lookups for the connection details based on a “Connection Factory.” This connection factory will have its connection URL and connection properties. TIBCO BW Application will receive that information and start connecting to that EMS Server.

You will know that you are using a JNDI Connection because the Connection Factory Type now will show JNDI. Also, you will require an additional resource name, JNDI resource, and your URL connection will be something like this…
