if you are looking for c# code, here it is.
| Code: |
public void InquireQueueDepth()
{
try
{
string qmgrName = "QMGR_NAME";
string svrconnChannel = "SYSTEM.DEF.SVRCONN";
string conName = "HOSTNAME(1414)";
string queueName = "ALIAS_QUEUE_NAME";
MQQueueManager qmgr = new MQQueueManager(qmgrName, svrconnChannel, conName);
if (qmgr != null)
{
MQQueue aliasQ = qmgr.AccessQueue(AliasQueueName, MQC.MQOO_INQUIRE + MQC.MQOO_FAIL_IF_QUIESCING);
if (aliasQ != null)
{
if (aliasQ.QueueType == MQC.MQQT_ALIAS)
{
MQQueue baseQ = qmgr.AccessQueue(aliasQ.BaseQueueName.ToString().Trim(), MQC.MQOO_INQUIRE + MQC.MQOO_FAIL_IF_QUIESCING);
if (baseQ != null)
{
if (baseQ.QueueType == MQC.MQQT_LOCAL)
{
string info = "Current queue depth of " + baseQ.Name.ToString().Trim() + " Alias (" + aliasQ.Name.ToString().Trim() + ") : ";
info += baseQ.CurrentDepth.ToString().Trim();
MessageBox.Show(info);
}
else
{
MessageBox.Show("Alias queue not pointing to a local queue and cannot inquire queue depth.");
}
}
baseQ.Close();
}
else
{
MessageBox.Show("Queue not an alias queue.");
}
aliasQ.Close();
}
}
qmgr.Disconnect();
}
catch (MQException MQEx)
{
MessageBox.Show(MQEx.Message + " " + MQEx.ReasonCode.ToString());
}
}

Replace the values in bold with your actual values.
string qmgrName = "QMGR_NAME";
string svrconnChannel = "SYSTEM.DEF.SVRCONN";
string conName = "HOSTNAME(1414)";
string queueName = "ALIAS_QUEUE_NAME";
hope that helps.

Of course for any client application, this application presumes that the qmgr is running, and that a listener is listening, and there's a working network.
A server-bindings equivalent "automation" app would work even if the qmgr was not running, and/or listeners were listening.

Why wasn't restarting these listeners part of the recovery process for the queue manager? Not any automated process perhaps but someone recovered the queue manager. They should either have restarted affected applications or paged the support areas for those applications.

Again, why isn't this part of the normal monitoring for the queue manager? The MQ admins should (and probably do) monitor queues for message backlog. Even if they're not prepared to restart your application listeners, they can page / notify the correct support area.

You seem to have been trying this for a very long time....

I still don't believe it's necessary.

Not necessary and not dependable/accurate.
