Hi,
I can not connect to a remote broker.
It is odd for me because it has already worked before.
I checked the channel, the listener and queue manager.
I read about SYSTEM.ADMIN.SVRCONN channel, it is not in queue manager.
I also tried the rfhutilc and it gave this error:
| Quote: |
14.32.53 2537 Channel not available or all connections in use
2537 Channel not available or all connections in use
2537 Channel not available or all connections in use
Error getting queue names |
My question is what I should check yet?
Thank you. |

| I defined the SYSTEM.ADMIN.SVRCONN channel but it didn't help. |

don't run around headless defining objects that you may not require. find out which objects you are using and if they exist. did you try telnet to ip / port to verify you have connectivity? did you check the queuemanager log? what about the number of connections? did you verify you did not exhaust that? what has been changed between "it worked before" and "now" ?
2537 returncore reads:
| Code: |
An MQCONN call was issued from a client to connect to a queue manager but
the channel is not currently available. Common causes of this reason code
are:
The channel is currently in stopped state.
The channel has been stopped by a channel exit.
The queue manager has reached its maximum allowable limit for this
channel from this client.
The queue manager has reached its maximum allowable limit for this
channel.
The queue manager has reached its maximum allowable limit for all
channels. |
did you verify all that?

| Is it a zOS queue manager without a Client Connection Facility, and thus limited to only five client connections? |

Dear Mr Butcher,
I've read the lack of SYSTEM.ADMIN.SVRCONN channel would cause this type of error.
The telnet is OK.
I checked the channels and port.
This connection worked a half year before.I don't know what has been changed because I was given this task lately. I try to learn it nowadays.
There are no connections on queue manager, yet.
As regard queue manager log I have just read it. |

It is on an AIX and I haven't the faintest idea about the limitation of connections. 
I'll check up. |

So it's just the normal default limit on connections then?
When you say "the connection worked half a year before" are you saying that no connections have been made to this queue manager in 6 months? It's been inert? If not, when was the last time a successful connection was made?
Has the AIX been restarted since the last successful connection?
When you say "the telnet is OK" does that mean you can telnet to the box (which proves nothing) or that you can telnet to the WMQ listener and see it react (which proves no network issues)?

Typically the disc device they're stored on. 
If you mean "what application" then vi, cat or any other text based tool works fine.
If they look like rubbish, then you're looking at the queue manager's transaction log files. These are in a binary format and contain nothing of any value to you.

Yes, it is a default limit on connections.
I connected to the server IP and the listener port by telnet.
Yes, the AIX was restarted due to a storage error. |

And have you located the response the queue manager logs now?

When? Has a successful connection been made since?
Better information, better advice.
Or raise a PMR. And be guided on what to look for.

Hm, my mother didn't tell me that this is just like Windows.
I restarted the queue manager and now it is OK.
Now again I thank you very much for helping me.

AIX tends not to be. In any sense. Including the "just restart it and it's fine".
I'd look (or get the sys admins to look) a bit closer at this "storage error" of yours.
But if it's working, that's a result.

I would be willing to bet that a process needed to make the connection died. That might indicate you system needs maintenance.
You might want to check that and apply maintenance as necessary. For both WMQ and WMB. |
