Are there any examples for a Java client to call MQINQ (MQSeries)to get the queue depth or maximum message length from an MVS queue. I can't find any examples.
thanks |

John,
here is a code snippet for you that should help.
| Code: |
if (hostName != null)
{
MQEnvironment.hostname = hostName;
MQEnvironment.channel = channel;
MQEnvironment.port = port;
}
MQQueueManager qMgr = new MQQueueManager(qMgrName);
int openOptions = MQC.MQOO_OUTPUT | // for put access
MQC.MQOO_INQUIRE | // check q depth
MQC.MQOO_INPUT_AS_Q_DEF | // for get access
MQC.MQOO_FAIL_IF_QUIESCING; // break on endmqm
MQQueue outQ = qMgr.accessQueue(qName,
openOptions,
null, // default q manager
null, // no dynamic q name
null); // no alternate user id
int curDepth = outQ.getCurrentDepth();
System.out.println("Current depth: " + curDepth);
|
If you really need a complete program, let me know and I can email you one.
There is also MQQueue method getMaximumMessageLength along with others for just about all the queue attributes.

Beauty, that looks it it might work, I'll try it out.
Do you also happen to have the length parameter? ie
would it be: getMaxMessageLength ?? |

I attempted to get the queue depth from MVS but got a 2038 return code indicating MQRC_NOT_OPEN_FOR_INQUIRE.
Perhaps MVS won't allow it, don't know at this point.
For the
int maxLength = qName.getMaximumMessageLength;
statement, it would not compile because
it is accusing me of attempting to reference it as an
'instance variable'. (although it may not work also for the same
reason as above).
So I'm still batting zero at this point. |

Did you open the queue with MQOO_INQUIRE?

You are simply missing () behind your method name. It should be
| Code: |
| int maxLength = qName.getMaximumMessageLength(); |

John,
Be sure to copy the part above that has all the open option flags:
int openOptions = MQC.MQOO_OUTPUT |
MQC.MQOO_INQUIRE |
MQC.MQOO_INPUT_AS_Q_DEF |
MQC.MQOO_FAIL_IF_QUIESCING;
and then use openOptions in the accessQueue method.

Alright, I've got both the QUEUE DEPTH and the MAX MESSAGE LENGTH returning now, but I realize it is actually the MESSAGE LENGTH that I need and not the max message length. I tried getMessageLength but it isn't recognized. Do you know the proper method to get this?
Also, is there a URL where these methods can be found?
thanks |

| Try looking at the WebSphere MQ Using Java manual. There is a link to it at the top of the page. |
