Compatibility between WebSphere 5.0 and MQ Series 1.2 Client

[0847]

Hi all, I am a software developer and currently working on the websphere migration project.

Since I am completely new to IBM MQ technology, please understand my non-sense quetions.


Current Network configuration
MQ Series Client(WebSphere v2.0)<--> MQ Series Server v1.2

Future Network Configuration
MQ Series Client(WebSphere v5.0)<-->MQ Series Server v1.2

As you can see, right now, we are not going to migrate MQ Series Server.

Here are my questions.

1. What version of MQ Series Client do I need to install on WebSphere 5.0 machine?

2. If I can use MQ Series Client v1.2 with WebSphere v5.0, then Is there anything I need to change for the MQ Series java client code ?

3. If I should use higher version of MQ Series Client with WebSphere v5.0 and the MQ Series java client code changes will be inevitable, Are there any resources that I can use for the code change ?

4.Since IBM MQ Series has been replaced with Websphere MQ, the questions I am asking above wouldn't make any sense at all. then what I should use instead ? what about WebSphere MQ?

Please give me some tips based on the fact that we should use MQ Series Server v1.2 for the time being.

Thanks..

Oh my....you are so far out of support it isn't even funny!

However the answers to your questions are..

1) I would go with the 5.3 client...but I have no idea if this will work with 1.2.

2) I am pretty sure that Java support only can in with CSD6 of 5.3 on the server. I think there was a support pack for earlier releases but again I am not sure it will work on a 1.2 server

3) There should be any changes needed.

My tip?...upgrade the server to 5.3 CSD 11 (if you are using windows). It should be a pretty painless upgrade and you reap far more benefits....like IBM support
4) MQSeries is a same as Websphere MQ. IBM just changed the name

Thank you very much for your tips.
Right now, I can't touch anything on MQ Server1.2
, which makes me much more difficult obviously.

All I can do right now is to install MQ Series 5.3 Client and change java client code accordingly.

Thanks..

Hi kevinf2349!,
I have a couple of more questions to ask.

1. What is MQ Client anyway?
1.1 Is it just jar files such as com.ibm.mq.jar ?
I just got that jar file from the running websphere 2.03
machine. I found that the size of that file is different
from the one in my machine(WebSphere 5.0)
1.2 If I use the old com.ibm.mq.jar, Does that mean I
shouldn't have to change any MQ Java client code ?
1.3 if MQ client is more than just jar file, Should I
use the higher version of com.ibm.mq.jar? and I have to
change the code accordingly?

2. Can I just install the lower version of MQ Client ?
Since I am not quite sure when the MQ Series server will be updated with the newer version Can I just use the MQ Client 1.2 on Websphere 5.3?
I am just wondering whether WebSphere and MQ Client are tightly connected.

Thank you very much.
