Support for LastResourceOptimization? (CICS)

[jensengel]

Hello,

we want to connect to CICS from JBoss and use CICS ECI Calls in global transactions. The manual for the IBM CICS Transaction Gateway reads that the J2EE Server would then need to have the "LastResourceOptimization" feature:

"Transaction Support
The cicseci resource adapter is defined as LocalTransaction. If your
server supports LastResourceOptimization, the resource adapter can
participate in a global transaction, provided it is the only
LocalTransaction resource that has been enlisted."

The idea is that the (only) not-XA-capable resource (CICS) is committed first, so the XA-capable ressources (JDBC) can be rolled back if the commit fails.

WAS 5.0 and WLS 8.1 do support this feature. What about JBoss?

It is implemented in JBoss4, it hasn't been backported to jboss-3.2 yet...

Last Resource only works with one local transaction, so you couldn't use this trick if you
have CICS with MySQL (which also doesn't support two phase commit) for example.
