Hi,

We have a V5.0 broker running on HP-UX.

with the mqsilist we see a dataflowengine running without a name.
When doing searching on the queues for the open handles of the PID we find the dataflowengine reading and written from and to the

QUEUE(SYSTEM.BROKER.CONTROL.QUEUE) TYPE(HANDLE)
PID(6450)
QUEUE(SYSTEM.BROKER.EXECUTIONGROUP.QUEUE)
TYPE(HANDLE) PID(6450)
QUEUE(SYSTEM.BROKER.EXECUTIONGROUP.REPLY)
TYPE(HANDLE) PID(6450)
QUEUE(SYSTEM.BROKER.IPC.QUEUE.6450.2008051008555431)
TYPE(HANDLE) PID(6450)
and the transmission queue to the configuration manager.

How can we delete the dataflowengine, as we cannot query the messageflows running in the dataflowengine as it has no name.

thanks for the reply

one exec grp always runs...

either it shows no name or it shows $MQSI_------ (Sorry i forgot the complete name)

It ll go on its own when you ll create some exec grp on your broker.

You're thinking of $SYS_MQSI. It's created temporarily if you deploy the topology without first deploying to an execution group.

This is because the broker always needs at least one execution group in order to handle the pubsub engine. If no execution groups are defined when you ask it to start sharing publications and subscriptions, the broker instantiates this temporary one.
