Connectable RAR to be usable as transaction CMR resource

[Ondřej Chaloupka]

Hi guys,

I would like check if it's possible/expected to create home-made RAR which could participate in transaction as CMR resource?

Why I'm asking.
I noticed that subsystem "resource-adapters" contains parameter 'connectable' with description 'Enable the use of CMR. This feature means that a local resource can reliably participate in an XA transaction'. Aka I would like check if I could create and use CMR txn resource that way?

(side note: I do not have any test for it and I would add it to my backlog to possibly create a test case for it.)

Thanks
Ondra

Hi Ondra,

Yes it's possible to create a custom rar partecipating transaction as CMR resource. Of course is up to RA implementation to support this. In fact our DSes are built on top of RA, and they could be used as an example of this implementation (even if not the easiest one)

If you have further questions, feel free to back to me

regards
