As we can Inquire a MQ Queues Objects using MQINQ call.
Why can't be use MQINQ call for Inquiring for Channel attributes. Why in all internets sites "Inquiring Channels" using PCF's (or) MQAI is oly given..
The MQOPEN is taking defaultly the value of MQOT_Q which is 1.
When i look at the header file, i saw MQOT_CHANNEL and the value is 6.. When i give the value and try to open the channel , I am getting MQOPEN failed with 2043..
How to Inquire channel objects easily using MQI's alone like easy as queues.. Please hel me out.. |

Well did you check the MQI for channel commands? Did you find an easy way?
No? So use the pcf commands already, they're made for that purpose.

MQINQ is provided for queues, because it is sometimes necessary for an application (not an administrator) to check certain values on the queue object it is using, for example whether triggering is set on. You'll notice that MQSET is only provided for queues and this is for a similar reason.

MQOT_* values are used in places other than MQOPEN, for example when looking at event messages that describe a change to a channel object by an administrative command, the event that is created for the audit trail of this, uses these values to indicate the type of object that was changed.

The return code MQRC_OBJECT_TYPE_ERROR (2043) is telling you that you cannot use that object type in an MQOPEN.

As already noted in your question, you must use the PCF interface. May I ask why it is your application needs to inquire details of the channel?
