I have an error for Windows client to MQ on AIX server.
Process(3884.1) User(mqm) Program(amqcrsta_nd)
AMQ9209: Connection to host 'P111 (......)' closed.
EXPLANATION:
An error occurred receiving data from 'P111 (......)' over TCP/IP.
The connection to the remote host has unexpectedly terminated.
ACTION:
Tell the systems administrator.
Being MQ administrator I am trying to fix this issue. I saw other posts with suggestion to do
ALTER CHL(SYSTEM.DEF.SVRCONN) CHLTYPE(SVRCONN) MCAUSER('mqm')
I found other chanels with svrconn types. Are they requireing this alter as well?
CHANNEL(CHANNEL1) CHLTYPE(SVRCONN)
CHANNEL(SYSTEM.AUTO.SVRCONN) CHLTYPE(SVRCONN)
CHANNEL(SYSTEM.DEF.SVRCONN) CHLTYPE(SVRCONN)
Is it possible to have the client PC P111 in other access lists to be modified in AIX? |

No you cannot alter a client Qmgr from ur AIX server unless u have access to remotely login to that server.
You will be MQ admin for the AIX servers which might be acting as hub. But if it is a problem with any object on the client Qmgr then it is the problem of the application team to find their amin and fix the problem, unless your support scope also involves resolveing application Qmgr connectivity issues aswell.. none-the-less You should ask the admin of that server to run the command on the SVRCONN channel CHANNEL1.

I am able to work in runmqsc as mqm via telnet. Do you mind any example of the command to try? |

Setting the MCAUSER to mqm will do nothing other than make the whole queue manager unsecure.
It certainly won't do anything to solve your network connectivity problem. |

I have quecked acl for mqm directories on other system. There is no rescrictions. So I don't see the reasons to have the error but it is. |

In my case p111 is a loptop with Windows. |

The reason behind the post was that, I read an article about a file called /tmp/mqseries.xxxxx being created and not deleted when a chennel ends abruptly.. however..they also mentioned tht the file had been moved to /var/mqm dir in V6, and the problem should be a rarity..
If there is a process again started with the xxxxx process id, then there would be a file name clash.. and the channel would stop. 
Offcourse I dint consider amqrmppa channel pooling.. may be kill the process altogather and start a new one.. hope.. there arent.. further implications of other channels getting affected by that.

Try that again and check its status...
