Hello ,
I am a newer for MQ and now writing a MQ client AP(MQ client 5.3) in C on AIX5.2.
I define two client connection channels in AMQCLCHL.TAB
...
channel(A) chltype(CLNTCONN) CONNAME('128.1.1.1(14100)') (TCP) QMNAME(GW_IN)
channel(B) chltype(CLNTCONN) CONNAME('128.1.1.1(14100)') TRPTYPE(TCP) QMNAME(GW_IN) SENDEXIT('mqexitc(ChannelExit)') RCVEXIT('mqexitc(ChannelExit)') SENDDATA(00070000)
...
My question are :
1. if I invoke MQCONN, which channel will be used?
2. if I invoke MQCONNX without MQCD. which channel will be picked up?
3. if I want to indicate channel B for MQCONNX, which fields in MQCD should be specified ? or does anyone have an example for this?
thanks very much
jason |

Read the client manual and come back with more focused questions.
The client manual (platform independent) will explain most of your questions...  |

| You might also want to look at the amqscnxc.c sample since it uses MQCONNX. |

Hello,
thanks for your replies.
When I set MQCD below , I got a error with Reason 2277.
The variable of SendUserDataPtr include '0' , some like that in AMQERR01.LOG,
My questions :
1. what is correct set for MQCD.SendUserDataPtr?
2. If I want to use client channel definition table for MQCONNX, the pointer to MQCD must be set 0. Is that necessary?
strncpy(ClientC.ConnectionName, "128.1.1.(14100)", (size_t)MQ_CONN_NAME_LENGTH);
Client.TransportType = MQXPT_TCP;
strncpy(Client.ChannelName, "B", (size_t)MQ_CHANNEL_NAME_LENGTH);
Client.ChannelType=MQCHT_CLNTCONN;
Client.SendExitsDefined=1;
Client.ReceiveExitsDefined=1;
Client.SendExitPtr = "mqexitc(ChannelExit)";
Client.ReceiveExitPtr = "mqexitc(ChannelExit)";
Client.SendUserDataPtr = "00070000";
Client.Version = MQCD_VERSION_4;
Connect_options.ClientConnPtr = &ClientConn_send;
Connect_options.Version = MQCNO_VERSION_2;
MQCONNX() |
