				HI All
 
We had a production issue   that client were not able to connect to the QMGR through the svrconn channel.
 
and client getting  error "MQRC_Q_MGR_NOT_AVAILABLE" 
 
 
i verified our config file qm.ini 
 
At present MaxChannels=300  and 
 
MAXACTIVECHANNELS is not defined but it defaults to  MaxChannels only. My doubt is as this parameter is absent in the file what value it has consider as default?
 
 
 
 
also in error log files we didnt see this messgae
 
AMQ9513: Maximum number of channels reached.
 
 
Also we have simulated this scenario un UAT  with same set up.... we Cannot make more then 232
 
Please advise |

				Hi
 
 
  There is one more attribute called KeepAlive, check what value you have given to that.
 
 
   Most of the time, the orphan channel process makes this issue.
 
 
   I think some time you will get this error too
 
       2009  0x000007d9  MQRC_CONNECTION_BROKEN
 
 
  Regards

				Hi,
 
we've had this same problem. Often badly written apllication client-connections stay connected inactive and this leads to the situation where connections are in max.
 
You need to set the KeepAlive-limit of the channel (+qmgr) and also fix KeepAlive from the TCP/IP as well.
