We are using Java to access z/OS queues, MQ version 6.
We tested to unplug the network cable,
and this is what happened :
a) the MQGET() produces a RC = 2009, MQRC_CONNECTION_BROKEN
b) exception has coded a MQDISC() that gives RC = 2019 HOBJ_ERROR
c) we plug the cable back
d) we reach to MQCONNECT() that goes OK
... but ...
the Queue Manager in z/OS displays a new channel instance !
I mean there are 2 of them !!
How can we avoid this ?
Is there any "correct" programming sequence for the RC = 2009 ?

Most of the time that I have run into RC=2009, it was when a program got a fatal error on an MQ call, and then continued to make subsequent MQ calls.

Usually and on the off chance that this is just a blip on the net I like developers to still attempt the close before they open a new channel. However they need to handle the possibility of an exception on the close...
Enjoy
