What do you want? Yes it is possible, no it isn't something you just turn on, and you should search the site since I know this has been discussed before....

There are several ways to do this, it will depend on your application/business needs. There really isn't sufficient information in your request to be able to answer it fully.
Questions would include:
Do you want a seperate file for each message?
Do you want to overwrite the same file every time a message arrives?
What platforms are you using?
Do you want the disk writting task to start automatically and run until you close it, or do you want the task to end when it gets a 2033 and restart the next time a message arrives?
Do you want the message to stay on the queue or can it be delete once it is written to the file?
You may want to check out some of the threads on here if you are just wanting to keep the messages for potential replay. There are some free utilities around to assist in this area.
Hope this helps |

You need to write a program.
Or buy a program.

If you want the program to process messages continuously as they arrive simply code it like this (pseudo code):
MQCONN
MQOPEN
loop:
MQGET WAIT, CONVERT, FAIL_IF_QUIESCING, SYNCPOINT
if QUISCE Then goto end
if NO_MSG_AVAILABLE then goto loop
WRITE FILE
MQCOMMIT
goto loop
end:
MQCLOSE
MQDISC
You could do it without syncpointing but this increases reliability - I would not suggest using a product for such a simple purpose. You get far more control by coding your own program.
You really need to tell us more about platform, languages you can use etc. |
