Hello Friends,
For some reason the code below displays the message :
Item count in bag = 2
This seems wrong, since I am expecting a single bag with
data about the SYSTEM.DEF.SENDER channel only.
Any ideas ?
| Code: |
mqAddString(requestsBag, MQCACH_CHANNEL_NAME, MQBL_NULL_TERMINATED, "SYSTEM.DEF.SENDER", &completionCode, &reasonCode);
mqAddInteger(requestsBag, MQIACH_CHANNEL_INSTANCE_TYPE, MQOT_SAVED_CHANNEL, &completionCode, &reasonCode);
mqAddInteger(requestsBag, MQIACH_CHANNEL_INSTANCE_ATTRS, MQIACF_ALL, &completionCode, &reasonCode);
mqExecute(connection, MQCMD_INQUIRE_CHANNEL_STATUS, optionsBag, requestsBag, responseBag, MQHO_NONE, MQHO_NONE, &completionCode, &reasonCode);
mqCountItems(responseBag, MQHA_BAG_HANDLE, &itemCountInBag, &completionCode, &reasonCode);
printf("Item count in bag = %ld\n", itemCountInBag); |
regards, Asad. |

You get back 2 bags as there are 2 pcf responses. The first gives you a bad return code, 3065/MQRCCF_CHL_STATUS_NOT_FOUND. The second bag has the 2nd returned code, 3008/MQRCCF_COMMAND_FAILED.
I dont really know bgas (I look through a trace after running your sample, to work out what is going on!), but I am guessing the count items is always the number of bags contained in the response bag, and ties up with the number of PCF responses. You need to cycle through the bags, processing each in turn to see what they contain/mean.
Personally I far prefer the PCF layer as it makes more sense and you have more control, but then you need to build your own control blocks to send so its not 'easy'. |

Okay, but how would I parse through these 2 bags ?
I want to extract the information from these bags
(e.g. channel name, channel status, etc) but don't know
how to 
Any C/C++ code would be very useful....

for example code which iterates through bags. you walk through them and query each in turn |
