Hello,
I'm using pcf in Java to ask the queuemanager about information of running client-server connections. This works well. But I know have problems to get this information out of a queue sharing group.
| Code: |
request = new PCFMessage (CMQCFC.MQCMD_INQUIRE_CHANNEL_STATUS);
request.addParameter(CMQCFC.MQCACH_CHANNEL_NAME, cHannelName);
request.addParameter(CMQCFC.MQIACH_CHANNEL_INSTANCE_TYPE, CMQC.MQOT_CURRENT_CHANNEL);
request.addParameter(CMQCFC.MQCACF_COMMAND_SCOPE, new String("*"));
//send PCF
try {
logger.debug("Sending PCF request... ");
responsesChStat = null;
responsesChStat = agent.send(request);
} catch (PCFException pcfEx) {
logger.debug("CC: "+ pcfEx.completionCode);
logger.debug("RC: "+ pcfEx.reasonCode);
logger.debug("Message: "+ pcfEx.getMessage())
}
|
The result is always the same:
CC = 2
RC = 2030 (MQRCCF_NONE_FOUND)
With COMMAND_SCOPE = *, the command should be executed on every active queuemanager in a sharing group.
I even get the 2030 RC, when the comand is executed on the queuemanager, where the client-server connections are established.
When I delete this line of code
| Code: |
| request.addParameter(CMQCFC.MQCACF_COMMAND_SCOPE, new String("*")); |
I get the correct result if the right queuemanager of the queue sharing group was chosen.

MQRC 2030 0x000007ee MQRC_MSG_TOO_BIG_FOR_Q
Did you really get MQRC 3200 (0C80) (RC3200): MQRCCF_NONE_FOUND?
Did you look up the Reason Code in the WMQ Messages manual? What did it say the rc means?

I stated the wrong rc.
I definitely always get this one:
3200 (0C80) (RC3200): MQRCCF_NONE_FOUND
The manual says
No items found matching request criteria.
An Inquire command found no items that matched the specified name and satisfied any other criteria requested.
But there are definitely channel status, which should be found.
Maybe there is another possibility to pass the asterisk? Is there a constat for that purpose? |

The above stated fragement of code does work.
It seems that I had some environmentally problems.
Thanks for your help.

Hmmm. Channel status comes in two flavors: current and saved. Current is for channels currently active; and current is the default according to the MQSC manual.
Is it possible that some of the channels you were hoping to see had disonnected, and therefore had no current status?

I monitored the connections with the MQ Administrator software. The channels were running when the pcf command was issued.
But I found out the follwoing:
If there are 0 or 1 active connections the command returns "3200 (0C80) (RC3200): MQRCCF_NONE_FOUND".
If there are at least 2 running connections, the command returns the correct result.
I think I will now open a PMR for MQ z/OS V6.
Thanks for your help. |
