Hi,
I am using WMB 8.0.0.1.
We receive a request as SOAP over HTTP.
at ESB we have to split the message into multiple parts and send them one by one to MQ.
Requirement is ROLLBACK ONLY failed messages and not the entire batch. We are supposed to continue processing till the last record.
Exception needs to be raised only for failed messages.
If I use a loop to send multiple propagate statements on any failure during the mapping or during the 'PUT to Q', the entire batch gets rolled back.
We thought of having a try catch node before this 'while loop' compute nde and then try to record the exception list in Catch path. And connect the catch path back to same while loop so that while loop processes from where it has left. We are setting suitable Environment variables to ensure while loop processes only from where it has left.
in the catch path we also include a flow order node to first send the message back to Main path and then Throw exception after all records are processed.
Conceptually this should work. But Looks like a complex solution for a simple problem. So Is there a better strategy? What approach did you take? |

I would not use WMB transaction mode for this (ie. I would set Transaction mode to off).
I would make use of GlobalCache and do all my transforms one-by-one into GlobalCache objects. When all records have been processed, drop the successfully transformed messages into the queue.
You need to be off 8.0.0.1. Your toolkit needs to be at least 8.0.0.2 iFix 001. Runtime similar.

nope, the answer is a continue handler in the esql. That was answered in the original post, but some people like asking the same question several times, maybe that way they get more answers ?... |
