Hi,
I want to use the MQ REST API to validate that the MQ server is up before submitting transactions.
I tried the following to see Queue Manager status:
https://qaesb01:9443/ibmmq/rest/v2/admin/qmgr/QM01/
and get the following output:
{
"qmgr": [
{
"name": "QM01",
"state": "running"
}
]
}
This is fine, but I want to target the SVRCONN (APP.SVRCONN), I have had a look but I am not able to find a way to do it, does anyone know where I can find a reference for this or if it is possible.
Regards,
Rayn |

Why exactly do you need to target the svrconn channel? SVRCONN channels are only active when an app is connected.

Don't do this. Its a waste of time.
What are you gonna do if you check if the queue manager is up with REST, its says its up, and one millisecond after that it does down? What good is your up status? Its worthless. You are going to isse your transaction anyway and have to deal with the failed MQ call anyway.
What are you gonna do if you check if the queue manager is up with REST, its says its down, and one millisecond after that it actually comes back up? What good is your down status? Now you are wasting time not issuing the transaction that would have worked.
Just submit the transaction and check the MQ Reason Code that the queue manager returns on every single MQ API call you issue.
When you need to talk with your buddy on the phone, do you call your buddy to ask if he is ready to talk, hang up and then call right back to talk for reals? No, of course not.

 wholeheartedly with Mr. Potkay.
Same applies when pondering (inquiring) current queue depth to see if there are messages to consume. Merely do a get, then check ReasonCode.
