Hi,
I am developing an app that would monitor the queues and channels of mqseries. I am using both the MQAX and MQAI components of mqseries. I initially setup my session and connected to the queue manager using the MQAX component (mqsession.accessqueuemanager). This works fine and I am able to retrieve the needed queue information (current depth, limits, etc). The qmgr object has a ConnectionHandle property, that I assumed would be same as the HConn handle when I issue the MQCONN api command. To monitor the channels, I have to use the MQAI components. I have successfully created and populated the MQAI bags. When I issued the mqExecute(hConn,parm,parm,,,) command using the ConnectionHandle of the MQAX QMgr object, MQseries rejected this and returned an error (2018). To debug, I issued a MQCONN and then used the HConn handle in the mqExecute call and this worked fine. I also compared the MQAX qmgr.ConnectionHandle vs the MQCONN.Hconn AND They are VERY MUCH different.
Any help would be appreciated...
thanks, |

after connecting to the queuemanager with accessqmgr, and creating your objects for COMMAND.RESPONSE.LOCAL and SYSTEM.ADMIN.COMMAND.QUEUE (request/replyQueues) make the call to inquire a channel status like this:
responseBag = adminBag.Execute(qMgrObj, 42, optionsBag, requestQueue, replyQueue);
(42=the MQCMD_INQUIRE_CHANNEL_STATUS selector)

the problem is the connection handle needed by the mqExecute command. Neither the qmgr.ConnectionHandle nor the qmgr.ObjectHandle work when I used in the mqExecute command. Only when I issued a separate MQCONN command and used the handle obtained from this that the mqExecute command worked.

right.
Don't use qmgr.ConnectionHandle nor the qmgr.ObjectHandle.
use it like this:
var gbl_qMgr = gbl_MQSess.AccessQueueManager(gbl_qMgrName);
THEN
gbl_responseBag = gbl_adminBag.Execute(gbl_qMgr, 42, gbl_optsBag, gbl_requestQueue, gbl_replyQueue);
kinda difficult without seeing what you are coding. I have already wriitten a complete MQ monitoring tool with MQAX.MQAI and it works perfect, I would like to help you. post your code and I can help you better.

WAIT.... something's wrong here...
MQAX MQSession.AccessQueueManager returns a queue manager object of type MQQueueManager.
set gbl_qMgr = gbl_MQSess.AccessQueueManager(gbl_qMgrName);
gbl_qMgr is of type MQQueueManager (not Long)...
mqExecute(HConn,,,,,) requires a HConn handle (of type Long).
using gbl_qMgr in mqExecute(HConn,,,) does not work.
ps.... I am doing this in Visual Basic.

ahh, well, I wrote my programs as web applications and used Javasrcript.
visual basic/ VBscript is very similar
here is the same in VB
Set qm = MQsess.AccessQueueManager("")
Set mqreplybag = mqadminbag.Execute(qm,11,optsbag,requestQ,replyQ)
see???

i find it odd that you were able to interchange the MQAX MQQueueManager object and the mqExecute(HConn) in Javascript. They are of 2 different data types. I also do a little javascript/vbscript programming and both of them treat an object datatype (ie, Object, Class) differently from a basic datatype (ie, Long, Integer). And in this case, MQQueueManager is an object, not a simple datatype that you can just use in the mqExecute command.
I may also try to convert my app (once it's done) to a web-service and try your suggestion if it works.
Thanks, |

it is so much easier than you are making it. try the above calls that are in VBscript and you will see.
