Hi,
I am going to dev applicaiton my client in Mainframes..I am thinking of using
Triggering to get the Messages from the LocalQueue.I have gone through
IBM Aplication programming guide.pdf
i have some doughts
1)
page 231 of the pdf
-----
Persistence and priority of trigger messages
Trigger messages are not persistent as there is no requirement for them to be so.
However, the conditions for generating triggering events do persist, hence trigger
messages will be generated whenever these conditions are met.
----
a)if the INITIATION Queue Crashes or Restarted there is a chance of loosing the Messages
since they are not persistance ? plz correct me if i am wrong?
b)since i have 2 Applications.In one senario(daily transactions happens bew client and server) and
second application(just sends some files end of the day to the Central Place)
for the second case i am thinking of using Triggering.
page 229
----------
2)Trigger monitors on OS/2, Compaq OpenVMS Alpha, Compaq
NonStop Kernel, UNIX systems, OS/400, and Windows
systems
Can i do triggering on Mainframe System(os 390). since my clients running in Windows XP
and Mainframe too..
What to You suggest go for Triggering or get the Messages in MQget(not unlimited Wait
,using Waitinterval)?
can any body share any working example program,since its easy for me to implement.
Plz share Your comments.

OK, lets try and take these in order. Right at the beginning you say:

There is NO client for the mainframe. Assuming you are talking about z/OS.
| Quote: |

There is no concept of a Queue 'crashing' Either MQ is avaialable or it isn't.
| Quote: |

For a trigger message, this isn't relevent. If *your* message is persistant, and therfore survives across a Queue Manager restart, then after the restart the trigger would be re-generated under the same conditions.

How is MQ going to differentiate between the 2 conditions. Either both will trigger, or neither.

Yes, the same as any other platform.

As stated above, there is NO client for z/OS.

That depends ( ) on your circumstances. If you are expectecting messages very infrequently, then triggering 'may' be the way to go. If messages are arriving on a regular basis, the maybe a 'daemon' type program is the answer. Or even, triggering, and then waiting for a "long" period before ending the triggered program. As always with MQ, the answer is: "It Depends".
Cheers,

No, it won't.
The OS/390 MQSeries software can not make a client connection to an external queue manager.
