Channel is in retry status in distribution setup.

If we ping the channel we are getting error

maximum number of active channels reached

Please find the error logs

EXPLANATION:
The channel program ended because an instance of channel 'DEF.ABC.C1'
could not be started on the remote system. This could be for one of the
following reasons:

The channel is disabled.

The remote system does not have sufficient resources to run another instance of
the channel.

In the case of a client-connection channel, the limit on the number of
instances configured for the remote server-connection channel was reached.
ACTION:
Check the remote system to ensure that the channel is able to run. Try the
operation again.

Kindly advice on it.

Determine why the channel is in retry, using the information provided in the error as a starting point, i.e. see if any of the stated conditions exist.

Resolve the problem.

Watch the channel restart.

Fairly obvious advice, but given the information you provided about as good as you're going to get.

You need to now look at the error logs on the remote MQ server.

As the Explanation suggests,
The receiver channel is either stopped or the Queue Manager could just not start another instance of "runmqchl" due to max channel limit being reached (default is 100, unless it has been increased by making an entry in the qm.ini file)

you can check the number of active channels running either by just counting the number of active channels inside mqsc utility or by using a series of commands piped together as below

dis chs(*)| runmqsc QMGR| grep RUNNING| wc -l

If the RCVR end of the channel has reached max channels or max active channels, alter these values in the .ini file for the qmgr.

bkiran2020,

I did a search on "max channels" of this section and on the fourth hit found a posting with a link to an example in the Information Center about Qmgr stanzas demonstrating the entries you are probably missing. If you keep looking, you will find many examples and explanations of why you should set them one way or another.

You should have gotten and error in your Qmgr error logs about reaching max channels.
