Hi Guys,
Can an application connect to MQ server in client mode though the MQ client is not installed on the box where we have application?
Thanks |

That's a protocol bridge.
To me "client mode" means that the application has connected using the MQI (directly or via JMS) over a MQ client channel. |

if application uses MQ API and has the client libraries in the application directory is it possible to connect to MQ queue manager?
If application uses client libraries, what all client libraries must be copied?
Is it required to set any environement variables?
Thanks |

Just install the client.
Really.
Anything else is a maintenance and change control nightmare. |

ok I would install client.
But I am not sure if application can use client libraries in their own directory and connect to the MQ queue manager. Because, I see there is no MQ client on the server and application directory has client library.
Can you guys pls let me know if application can connect like what I mentioned above? |

It depends on what you mean by "client libraries".
It's *possible*.
It's always *a bad idea*.
What version are those libraries? Are you sure? how do you update them? |

com.ibm.mq.jar they are version 6
I didn't update, I was looking into the server and found them |

| Java apps don't need the full client, but copying the IBM MQ jar files means they will get forgotten about and not updated. |

I don't think that copying jars is supported anymore, is it? I thought that IBM wants a proper client installation.
At least, that's the story I've been telling everyone at my site. Encourages them to listen to my opinions about how to install those darn jar files...

It's a grey area. The recommended way is a full install, but I believe support will be offered if you've just installed the jar files.
Probably "do a full client install and call us back if it still doesn't work" 
The advantages of doing a full install over just dumping the jar files in the classpath are many, and have been enumerated on the forum.
It's certainly the best way, and I congratulate you on your crusade.
