Hi Guys,
How can we view the existing JNDI connections associated with a QM. I have made a connection to a Remote Queue Manager via MQ Explorer, but I couldn't see any JNDI connections. Apart from making JNDI connections, is it possible to look for the existing via MQ Explorer. If not, how can view them.
Also, is JNDI mandatory for a java application to put messages to IBM MQ and using JMS transport.
I have gone through the whitepapers provided in the IBM developerworks and was able to understand the concepts. But still, I think I am lost somewhere.
Many thanks in advance! |

JNDI is not mandatory to create a JMS connection to a queue manager. It is just the most commonly used way as it is the most generic one.
When using JNDI the properties of the connection factory are set up in the JNDI and the object retrieved is ready for use.
You can look at the samples if you want to set the properties on the connection factory yourself.
There is no difference between a "JNDI" connection and a regular JMS connection from the server (qmgr) side. So unless you know the application and the channel it uses there is no way to distinguish...
Have fun

Another thing you could look for are channels that have an RPRODUCT of MQJM or MQJN. Those would be JMS connections.

This may well work for the client connections, how about "bindings" i.e. server connections?

Correct, the RPRODUCT only is a DIS CHSTATUS feature, so only works for client connections. It would have been a nice feature to also include RPRODUCT and RVERSION for bindings/local connections.
