MQSeries.net :: View topic - Inquring channel status through PCF commands

Hi All;

I am trying to build a PCF command to get the status of the channel.
The code is in c lang.

Here is the code for ur kind ref:

//Geting the Length for PCF to be build
AdminMsgLen =MQCFH_STRUC_LENGTH
+ MQCFST_STRUC_LENGTH_FIXED
+ CHANNEL_NAME_LENGTH ;

// Creating Command (PCF) message
pAdminMsg = (MQBYTE *)malloc( AdminMsgLen );
pPCFHeader = (MQCFH *)pAdminMsg;
pPCFHeader->Type = MQCFT_COMMAND;
pPCFHeader->StrucLength = MQCFH_STRUC_LENGTH;
pPCFHeader->Version = MQCFH_VERSION_1; //this ver. I am using//
pPCFHeader->Command = MQCMD_INQUIRE_CHANNEL_STATUS;
pPCFHeader->MsgSeqNumber = MQCFC_LAST;
pPCFHeader->Control = MQCFC_LAST;
pPCFHeader->ParameterCount = 0;

pPCFString = (MQCFST *)(pAdminMsg + MQCFH_STRUC_LENGTH );

// Setup parameter block
pPCFString->Type = MQCFT_STRING;
PCFString->StrucLength = MQCFST_STRUC_LENGTH_FIXED + MQ_CHANNEL_NAME_LENGTH;
pPCFString->Parameter = MQCACH_CHANNEL_NAME;
pPCFString->CodedCharSetId = MQCCSI_DEFAULT;
pPCFString->StringLength = MQ_CHANNEL_NAME_LENGTH;
memset( pPCFString->String, '\0', MQ_CHANNEL_NAME_LENGTH);
memcpy( pPCFString->String, "ABC.TO.XYZ", sizeof("ABC.TO.XYZ"));

// Setting MQMD Header
memset(md.ReplyToQMgr, '\0', MQ_Q_MGR_NAME_LENGTH );
md.MsgType = MQMT_SYSTEM_FIRST;

memcpy(md.ReplyToQ, replyQ, MQ_Q_NAME_LENGTH );
memcpy(md.Format, MQFMT_ADMIN, 8 );

// Setting Put Message Options
pmo.Options = MQPMO_NO_SYNCPOINT;

// Putting Command message on Command Queue
MQPUT( hConn,
hAdminQ,
&md,
&pmo,
AdminMsgLen,
pAdminMsg,
&CompCode,
&Reason
);

if (CompCode == MQCC_OK)
{
printf("nPut Sucessful");
}

else
{
printf("n Put UNSucessful CompCode , Reason = %d , %d ", CompCode , Reason);
return;
}

free( pAdminMsg );

//
Now my problem starts here. I want to know what is the structure type of the response message and also the length of the mesage I have to allocate the buffer to get it.

Is the code below for getting the response is OK.
But with this code I am not able to read the message from the queue although the PCF command has sucessfully executed and the mesage is lying inside the Q.

//

AdminMsgLen = MQCFH_STRUC_LENGTH
+ (MQCFST_STRUC_LENGTH_FIXED )
+ MQ_CHANNEL_NAME_LENGTH ;

pAdminMsg = (MQBYTE *)malloc( AdminMsgLen );

Thanks for any kind suggestion in advance.
