I have an application that I wrote using MQI C++ classes which can use a client connection to get and put messages from and to a queue. I use ImqQueueManager::setChannelReference and everything works fine.
I now need to do some operations with the MQAI mqExecute function on the queue manager that I'm accessing via the client connection. In order to get a handle, I'm trying to use MQCONNX, but it's failing every time with error 2058. The following is the code I use:
| Code: |
MQCNO lmqod_conn_options = {MQCNO_DEFAULT};
MQCD lmqod_channel_def = {MQCD_CLIENT_CONN_DEFAULT};
strcpy(lmqod_channel_def.ChannelName, (MQCHAR *) imqod_channel->channelName());
lmqod_channel_def.HeartbeatInterval = imqod_channel->heartBeatInterval();
strcpy(lmqod_channel_def.ConnectionName, (MQCHAR *) imqod_channel->connectionName());
lmqod_channel_def.TransportType = imqod_channel->transportType();
lmqod_conn_options.Version = MQCNO_CURRENT_VERSION;
lmqod_conn_options.ClientConnOffset = 0;
lmqod_conn_options.ClientConnPtr = &lmqod_channel_def;
MQCONNX(imqod_queue_mgr->name(), &lmqod_conn_options, &lmqh_connection_handle, &lmql_completion_code, &lmql_reason_code); |
I also compiled the sample program amqscnxc.c and tried running it, and got the same error (2058) in failure. I know the names I'm using for host, channel and queue mgr are correct, because these same names work when I use the C++ class mentioned above - that's the "imqod" you see in the code snippet above. Any idea what I'm missing here?
(I'm using Websphere MQSeries 5.3 in a Windows XP environment)
Thanks so very much.

| Specify the TCP port number as well. Ensure that a listener is running at this port and that the server connection channel is started. |

How do I specify port number? <host name>:<port number> for connection name?

Port numbers in connection names are always enclosed in parentheses.
So <host name>(<port number>).

Well, I tried that (adding "(1414)" to my connection name) and it didn't change a thing.
I think there's got to be some value that's defaulted or properly set in ImqChannel or ImqQueueManager::SetChannelReference which is not being set when I try to use the raw form of MQCONNX. The connection works the C++ way, I successfully get and put messages! But I need that HCONN handle, without it I can't use the mqExecute function.

Oh, and I should add: I checked the status of the server connection channel. On MQ Explorer, the channel status says it's inactive, but when I right-click and select "Start", that does nothing. In addition, the fact that it's (supposedly) inactive doesn't hurt anything when I'm using the C++ object to make the connection.

The system where you are running the application, do you have MQSERVER environment variable set? If yes, remove it and try running your code.

Thanks for the late reply. I since found the problem - I had been linking my app to the server library, mqm.lib, instead of the client library mqic32.lib. It now works just fine.

AFAIK, this shouldn't really matter |
