Hi,
Is there a way to get the list of queue names for a QueueManager without using PCF? PCF package is not available in our environment. Is it possible to use the MQCMD_INQUIRE_Q_NAMES in a java program to get the list of Queue names?
Thanks for your help. |

Why make it so difficult. You did not say it had to be programatical ... but anyway how about:
| Code: |
| echo "dis q(*)" | runmqsc MYQMGR |
run by a user in the mqm group...
Enjoy

The only environment PCF wasn't availavle was zOS (pre V6)...is that the environment you're in? If so, you can still send "plain text" command messages to the command server...
Otherwise, FJ's solution is the best, but it only works if you're local to the qmgr ... (although I thought Paul C have a s/p for "remote" runmqsc...)

Hi All,
Thanks for the reply.
We are still in 5.3 environment. The requirement is for a Java program to retrieve the list of queue names for a given Queue Manager. Is there a way to retrieve the queue names from a Java program in a non-PCF environment?
I tried sending messages to the command queue to display all the queues using a Java program. But the message I sent just sits in the Command Queue meaning its not executed.
Thanks for your help.

Is the command server running? "dspmqcsv qmgr" ? if not, start it: strmqcsv ....

The only cases where it's really a good idea to get a list of queues on a queue manager is if you are writing a monitoring or management solution.
It is an extremely bad idea to write a business application that reads the list of queues on a qm, and picks one to use for it's business logic.

We are trying to create a web application to monitor queues for a queue manager. Right now we have the list of queues read from a file but we are trying to replace it with code to dynamically retrieve queue list for a given queue manager.

The QueueManagers belong to a different group which will not allow us running any command on them. The only option we have is to get the list of queues using MQ Java API. We do not have PCF in our environment and so Im unable to use it.
Thanks for your help.

That doesn't make any sense ... with the exception of zOS qmgrs before V6, ALL qmgrs support pcf ...can you explain exactly what you mean by this?

Probably they do not have the rights to access the SYSTEM.ADMIN.COMMAND.QUEUE, so its not possible to send PCF commands. |

Yes. We do not have the rights to access the command queue.

Then you are out of luck. There is no way to get a list of all the queues strictly thru the MQ API from the QM, unless you go thru the command queue.

Weeeelllll.... a queue name is at most 48 characters long, with each character being one of (A-Za-z0-9/.%_<space>). That means one could write a program that would issue an MQOPEN for each 67^48 possibilities. It's a little bit smaller than that, as spaces are forced to only be trailing characters, not leading or embedded characters. So it's really 66^48 possibilites - with spaces added to any possibility that is less than 48 characters long.
And ... eventually one would arrive at a list of queue names. But I wouldn't hold my breath.
Can someone remind me how reliable MQINQ is compared to PCF? I seem to remember that it was not quite as guaranteed? That is, the data is not going to be as accurate - and it's more limited too.
