| APPC ? That sounded like SNA problem. What platform are these? Have you tested the SNA connection if the client can reach the server? |

thanks,
i'm on windows 2000 platform. My program executes in the server machine.
when I start my service , I can not connect to the Queue manager
and the error I received in the Event Viewer is
"The APPC communications program could not be loaded.
The attempt to load the APPC library or procedure 'wcpic32' failed with error code 126.
Either the library must be installed on the system or the environment changed to allow the program to locate it.
"
which library should I install?
any help will be appreciated
thanks |

Ask your network administrator.

thank you jefflowrey,
I will like to take this opportunity to ask another question.
i link my program with all these libraries:
imqb23in.Lib
imqb23vn.Lib
imqs23vn.Lib
imqc23in.Lib
imqc23vn.Lib
imqs23in.Lib
mqic32.Lib
mqiccb32.Lib
mqiccbb.Lib
mqm.Lib
mqmax.Lib
mqmcb32.Lib
mqmcbb.Lib
mqmcics.Lib
mqmcics4.Lib
mqmenc.Lib
mqmsom.Lib
mqmtux.Lib
mqmvx.Lib
mqmvxd.Lib
mqmxa.Lib
mqmzf.Lib
mqutl.LIB
I removed all the library and I just left
imqb23vn.Lib
imqs23vn.Lib
I did not have an error in the Event viewer.
but my service does not connect to the queue manager.
may be it's anothe problem.
PS: My application run in the same machine where the MQseries server is installed.
question1:
are these two libraries
imqb23vn.Lib
imqs23vn.Lib
sufficient?
thanks |

Then you probably have a security problem with the service user.

Yes, the way to resolve the security issue is to authorize the service user to MQSeries.
I would recommend not running your service as LocalSystem.

Jeff
I am having some issues with a VB.Net service that I am writting and I would like you to expand on:

What is the problem with doing this? Is it purely security? The problem I am having is that when I try to create a listener in my service the service just stops doing anything (no event messages get written but the process still shows as "started"). I have searched on the Internet and have found nothing that gives a good explaination of the differences in the service type. |

how have you solve this?
the reason code is 2058 . I think this is a security problem.
My service is running in the same computer as my MQserver and i'm logged as administrator.
any issue to solve this?

| 2058 is usually a qmgr name error. Double-check that the name in your program and the actual qmgr name are identical (eg, same case). |

When running the same code in a user interface i can connect to my queue manager.
so I think the name of my queue manager is correct.
I also run the service as administrator I faced the same problem
reason code 2058.
I have to choose an account when running my service.
please i need some advice
thanks |
