Hi All,
I have an API Exit to track some my MQ messages. When I deploy the API Exit, it starts more than one instances. I am trying to use the common ExitUserArea to transfer some information between the API Calls but due to this several instances I could not acheive this.
Is there anyway to restrict the number instances starting up when the API Exit laoding.
I am using C for windows to create the API Exit.
Throw some light on this, If you have come across this situation.
Thanks
Jeeeeva |

The API Exit is a shared library. Each separate process that connects to a queue manager will load the shared library. There is only a single copy of the executable code section in memory but each process gets it's own copy of the data section. You need to implement a global IPC mechanism, like shared memory, and access it from the exit.

Hello,
We cannot restrict the shared object to instantiate when there is a request.
you can do it through putting explicit condition inside the API exit and return / supress the functions that may get executed further and come out the current execution of API Exit Instance.
When there is an event/request the Shared Object is to give copy of executable code with data segments.
Regards,
Vijay. |
