Hi,
I'm writing a simple VB gui to put and take messages of a queue hosted on a remote queue manager (unix); I also have a simple command line version written in Java. The thing is the Java version works OK, but I get a 2035 error with the VB client.
I connect to the QM in java as follows:
MQEnvironment.hostname = hostName;
MQEnvironment.channel = "SYSTEM.DEF.SVRCONN";
MQEnvironment.port = port;
qMgr = new MQQueueManager( manager );
and all is fine....
in VB I ....
Dim CNOCD As MQCNOCD
MQCNOCD_DEFAULTS CNOCD
CNOCD.ChannelDef.ConnectionName = hostname & "(" & port & ")"
CNOCD.ChannelDef.channelName = "SYSTEM.DEF.SVRCONN"
CNOCD.ChannelDef.TransportType = MQXPT_TCP
MQCONNXAny queueManagerName, CNOCD, Hconn, CompCode, ConnReason
and I get a 2035 when I hit MQCONNXAny. So, I guess, my questions are:
1. What is the difference between the java client and the VB client?
2. Is java embedding a guid/uid during the connect ?
3. How do I get the VB client to emulate the java client ?
cheers,
Jeremy |

RC 2035 is MQRC_NOT_AUTHORIZED, so VB client works correctly.
It's known security hole in java client. If you don't set MQEnvironment.userID it takes mq admin user instead.
Just use authorized user or set MCAUSER of SYSTEM.DEF.SVRCONN to one.

Hi,
thanks for the reply; so I see I have two options (although I'm thinking only one is OK!)
1. Add the MCAUser at the client before calling connect, as follows:
CNOCD.ChannelDef.MCAUserIdentifier = "AUTHUSER"
2. Set the MCAUSER in the actual channel definition, at the server host, as follows:
DEFINE CHANNEL ('MY.CHANN') CHLTYPE(SVRCONN) +
....
MCAUSER('AUTHUSER') +
...
In case 1. above, I'm trying to get onto a channel with :
MCAUSER(' ')
Cheers,
Jeremy |
