You could use the supportpac MA01 (the q utility) or adapt the sample amqsput programm and recompile it with a larger buffer size.

I forgot my favorite admin tool, the supportpac MO71 (MQMON).

| Looks like there is no MQSC command available to clear with API calls. Maybe that's only MQExplorer feature. |

you cant clear a queue when it is in use. you have to find out the aplpication that has opened the queue and stop that.
do a dis qstatus(queuename) type(handle) all .
search the forum for more details. This is just runmqsc command. |

sandiksk,
the tools I described above read the contents of a message one-by-one. So they are able, to "clear" a queue, which is in use. But the MQSC command CLEAR QL(...) only resets the pointers to the messages and is much faster, than reading all the messages with MQGET.

And it makes sense that you wouldn't be able to use runmqsc to GET messages, since runmqsc is not otherwise an MQ application - it doesn't use the MQ API. Why they didn't add it to the PCF command is a different question, since the command server is already an MQI application. Probably, though, the assumption is that if you're connecting to the queue manager already and wanting to clear a queue - you can just open and get the messages yourself so why should the command server do it for you?
