Please explain me briefly development steps and property values for trigger and trigger services.

Thanks and Regards,

Hi Anil,

Below is the way I implemented the throwExceptionForRetry1) In trigger set Max retry attempts(n) and Retry interval(m).Service will be retried n number of times each waiting for m seconds.

2)In our main service we have to set the logic in the Catch block using two services.

a)pub.flow:getRetryCount (to get the retry count at runtime)

b)pub.flow:throwExceptionForRetry(will retrigger data from the Broker when the set exception occurs)

Everytime service fails the “lastError/error” is checked for the error we want to retry (try using pattern matching).

We will check for the retry count (getRetryCount) if it exceeded the max value(use sequence).

if retryCount <=maxRetryCount then call service throwExceptionForRetry.
Please use a flag to jump to conditions…

Thanks,
Amol

Anil - have you looked at the documentation before posting on here? It’s the best place to look (documentation is pretty good with SoftwareAG)

In the *_Publish_Subscribe_Developers_Guide.pdf is where you’ll find most information relating to pub/sub mechanism… In particular the section called “Configuring Transient Error Handling”.

In the *_Integration_Server_Built-In_Services_Reference.pdf there’s information on the built in services you should use (throwExceptionForRetry and getRetryCount) as per amol’s post.
