Inquire on the queue

You can inquire on queue attributes. See MQINQ. You can set a small subset (7 items) of these attributes. See MQSET.

code::

  import sys 
  import pymqi 
  from pymqi import CMQC 
  queue_manager = 'M801' 
  qmgr = pymqi.connect(queue_manager) 
  queue = pymqi.Queue(qmgr, 'CP0000',pymqi.CMQC.MQOO_INQUIRE+pymqi.CMQC.MQOO_SET) 
  inq =            queue.inquire(pymqi.CMQC.MQIA_INHIBIT_GET) 
  print("pymqi.CMQC.MQIA_INHIBIT_GET",inq) 
  inqcd =            queue.inquire(pymqi.CMQC.MQIA_CURRENT_Q_DEPTH ) 
  print("pymqi.CMQC.MQIA_CURRENT_Q_DEPTH",inqcd) 

After a successful MQINQ() you can use get the prettified attribute name

      x = queue.inquire(pymqi.CMQC.MQIA_CURRENT_Q_DEPTH) 
      print(queue.inq_fieldName,x)   

displays

b’CurrentQDepth’ 0

Set an attribute on the queue

Trying to use MQSET with CMQC.MQIA_MAX_Q_DEPTH fails with Reason 2067: FAILED: MQRC_SELECTOR_ERROR. What do you mean, I can’t set the maximum queue depth?.

using MQSET with the above code

  y = queue.set(CMQC.MQIA_TRIGGER_DEPTH,3) 
  print("Set",y) 

gave

  Set None
