Do you mean the version of the queue manager to which the application has a client connection?
a) No
b) Why? It makes no difference to the application and, if the application is attempting to use version specific features, I put it to you that the version of the MQ client in use is of greater impact than the client side code.
Or don't you mean that?

The main MQ client APIS do not provide this level of information, because it is only relevant to administrative applications, and not to business applications.
There are a variety of PCF messages that can be sent by a client application. These form an administrative API that is, for example, used by MQ Explorer.
If you can find the relevant information available from MQ explorer when MQ Explorer is using a client connection, it is reasonable to expect that there is a PCF message that will return the same information.
It is not reasonable to expect that some random client application will be able to issue PCF messages, nor be authorized to do so. |

Phew, luckily for me this is indeed an admin utility 
I'll have another trawl thru the PCF values

If you need an admin utility to tell you what version of software you're using where, you may want to tighten up your installation control processes just a hair.
Especially as this utility can't list all the servers on which WMQ has been installed, for which you require manual records.

For any subsequent forum searchers, the answer is use PCF and ask for MQIA_COMMAND_LEVEL. Just like in DIS QMGR ALL, it returns a number such as 600, 710 (MQ 6.0.0, 7.1.0 respectively)
cheers

Without using PCF, an application program can open the Queue Manager object for inquiry (eg. in C, ObjDesc.ObjectType = MQOT_Q_MGR; OpenOpts = MQOO_INQUIRE + MQOO_FAIL_IF_QUIESCING; MQOPEN....) and then inquire (using MQINQ) on the integer value of MQIA_COMMAND_LEVEL.
The need for a typical application to know this information is highly questionable.

All,
There is even an simplier solution as long as the 3 digit release number is ok (vs the 4 digit release). i.e. 700, 701, 710 or 750
| Code: |
MQQueueManager qMgr = new MQQueueManager("MQA1");
int cmdLevel = qMgr.getCommandLevel(); |
