This seems like a simple problem but it has me a bit perplexed.
A sender channel having issues starting Continually says 'RETRYING', investigated the amqerrlog and the eventvwr and see:
| Quote: |
AMQ9558: Remote Channel is not currently available.
EXPLANATION:
The channel program ended because the channel 'QM654GRE.TO.QM_REPOS' is not
currently available on the remote system. This could be because the channel is
disabled or that the remote system does not have sufficient resources to run a
further channel.
ACTION:
Check the remote system to ensure that the channel is available to run, and
retry the operation.

I resolved the channel and reset both channels, but it continues to give this message, even though I am able to Telnet to the box
both sides run mq5.3
The sender channel is on a QM on Windows.
By the error it appears the issue is on the remote Linux QM. Other Queue managers on the windows box have Sender channels connected to the same Qmgr, same port. Everything ran fine ...until we rebooted the windows box ..now they all run with the exception of this one Sender Chl..
has anyone seen this issue before?
Im considering two things I have seen..
How I can use AdoptMCA and raising MAXchannels on the Linux box.
Anyone have any info they would like to share? |

Have you tried stopping the Channel and pinging it to validate that the remote reciever is properly defined?
Run the following on the Linux server to see how many channels are running:
ksh
set -o vi
echo "dis chs(*)" | runmqsc | grep RUNNING | wc -l
You may have to increase the MaxChannels and MaxActiveChannels. If they are not specified in the qm.ini file the default is 100.

Interesting. Thank you Chris.
I will check this first thing in the morning, So if I want to add more MAXChannels, I can change this in the qm.ini and restart QM?
Is this also where I would put the ADOPTMCA, but that is only used on the Sender Channels correct not the reciever. The sender is on Windows.
Sounds like increasing MAXChannels and using AdoptMCA would help tremendously, do people use Heartbeats along with AdoptMCA often? |

BTW, the command is "ping chl(CHANNEL.NAME)"

Yes on the Linux side.

Yes but the stanza is AdoptNewMCA.

If I were you I would look more closely at why your Sender Channel is going into RETRY status. It could be related to the MaxChannel/MaxActiveChannels threshold on the Linux Server but then again it may not. If you are exceeding the MaxActiveChannels threshold there will be entries in the /var/mqm/qmgrs/QMGR/errors/AMQERR0*.LOG's on the Linux Server telling you as much. If there are more serious issues you may find FFST files in /var/mqm/errors.
Lets get this Channel running before we start tweaking things. For a better understanding of AdoptNewMCA look in the WMQ Systems Administration Guide.
For a better understanding or Heartbeats or the HBINT Channel attribute look in the WMQ Intercommunications Guide.
