Hi,
One of the user is facing 2009 ( Connection broken) error while connecting to one of the svrconn channel. From MQ perspective I checked that qmgr and listerners are up and also the svrconn channel is running with some 27 instances connected to it.
The user is saying that he is able to connect successfully for first 20-30 connections and for later connections they are facing this issue.
There is no max connection defined in .ini config files.
Would anyone please provide suggestions on this issue. |

So it will 'default' to the stated maximum as listed in the Info Centre.
What is the aggregated number of connections? What version of WMQ etc.?

Its version 6.0.2.7 on linux.
And 40 connections should be in the default range I believe. |

A bit back-level I believe.

Yes, it should. However, is that the total number of connections? Are a number of different applications connecting, each with a possible 40 connections?

Did anybody talk to the application developers to determine the connection needs of the application? I guess that the application defined a max poolsize of 30 and that may be well below the application's needs....
However the 2009 return code makes me think it's more likely that the qmgr has the default number of max channels (100) specified and the rest of the connections are already taken....
Make sure to evaluate the total need of connections to the qmgr (chl of any type), check the max connections for each svrconn chl(V7) (multiply by 2), check the total number of connections needed (not present) and multiply by 2.5... This should give you some breathing room. Check the channel stanza and implement.... Finally restart the qmgr.
