I want to list all local QMs in my Java App.
how to get these QMs' name and current status?
Is it possible to do it with JAVA API?
Thanks!

There is no api for this. You can issue a system call to launch 'dspmq' with redirected ouput and then parse the redirected output from your java app.

thanks Charlie!

Maybe they should make another SupportPack. 
Anyway, as my OS is windows, so I am trying to get those information from Registry on Windows.
You ideal is simple and it should can be applied in Unix.

Hi,
On Unix can you not just parse the mqs.ini file? Of course that only give the names not the running status.
Cheers

Hi,
There is no MQ system component that your application can talk to - only the queue managers of each MQ system.
What is so hard about issuing the dspmq command from Java and parsing the results? You will get a list of ALL queue managers on the box and their current status.

Sure you can. From a shell script, you just do:
| Code: |
#!/bin/ksh
#
let n=0
cat /var/mqm/mqs.ini | while read line
do
case $line in
Name=* )
echo "Queue manager name = " ${line#Name=}
esac
done
exit 0

| I'm not sure that I'd say the java api is weak. Are you looking at the base MQ java classes or the PCF classes that ship with SupportPac MS0B? If you want to do administration, you need to use MS0B. |

It seems that we can't get the local queue manager information from PCF class in MS0B pack.
On windows plat, we can use JNI method to access the registry and get the related qm info. I have tried it.
thanks everyone! |

Maybe you are weak in Java!!!!
This is as simple as
| Code: |
Process l_oProcess = Runtime.getRuntime().exec("dspmq");
BufferedReader stdInput = new BufferedReader(new InputStreamReader(l_oProcess.getInputStream()));
|
And it will work on both Windows and Unix |

Provided, of course, that dspmq is on the PATH of the current environment...

vennela, you are right, I am not very familiar with JAVA and MQ, so I hope there have all kinds api to do everything, like adding queue dynamicly and so on. Maybe I should not say that... 
BTW, On windows platform, I need get all exist queue managers and their available ports.
Thanks for your help again. |

Cyberimp:
If you are on the windows platform you will need to use the windows API to access the registry. Of course that's not going to happen (security)
Why do you need the ports?
This enquiry would only work on the current platform anyway.
So you could connect in bindings mode: no need for port number.
You would need to know the channel though.
Much easier way to get what you need: Talk to your MQ administrator. He'll fill you in on what you need to know and tell you which programming books you need to read.

You will have no problem about creating a dynamic queue as a temporary queue. For the permanent kind you should have the MQ Admin create them.
Enjoy |

Just to clarify this comment:

Binding Mode:
The ONLY thing you need is the queue manager name. Although, you can set the other fields to null.
| Code: |
MQEnvironment.hostname = null;
MQEnvironment.channel = null;
MQEnvironment.port = 0;
//
MQQueueManager _qMgr = new MQQueueManager("MyQMgrName"); |
Client Mode:
You need 4 pieces of information:
| Code: |
MQEnvironment.hostname = "10.10.10.10";
MQEnvironment.channel = "MY_SVRCONN_CHL";
MQEnvironment.port = 1414;
//
MQQueueManager _qMgr = new MQQueueManager("MyQMgrName"); |

Yes and I should take more time on the MQ books.

well, maybe after I finish all the MQ ebooks, our team will have the MQ admin.
Thanks for your and RogerLacroix's help. |
