There are two aspects to this: will it work, and does your license cover it. As far as the technical issues go, I have every reason to believe that the JMS client bundled with WAS5 is capable of making XA connections to remote queue managers over tcp/ip, and therefore can be included in a distributed transaction with any JDBC2 XA-capable resources that are supported by WAS5.
On the legal side, I'm not the definitive source, but when I last asked I was told that the WAS5 license does cover this scenario, and ETC would not be required.
Sorry about the mixed messages - there is plenty of room for confusion because WAS5 comes with an embedded JMS provider as well as three bundled JMS clients (generic, embedded, MQ). It doesn't take much for people to get at cross purposes as to whether they are talking about the capabilities of the clients or the embedded provider, and that's before you ask what the licenses permit.

Greetings,
I looking for some clarification on a hot topic here. Our environment has this (basic) configuration:
Server1: WAS V5 (Appl Server) Server2: Oracle 9i (Database) Server3: WMQ V5.3 (Messaging)
Here's my question -
If I want to perform 2-phase commit (2PC) transactions and have WAS V5 act as the transaction coordinator between the Oracle database resource and the WMQ message queue resource, will the 'XA-capable' client distributed w/ WAS V5 be sufficient, or do I need to install the WMQ Extended Transactional Client (ETC) product offering??? (Note that the WMQ server is NOT co-located w/ WAS)
We've gotten mixed messages from IBM on this and I'd like to hear from IBM and/or others w/ experience with this type of configuration. The ETC costs as much as a WMQ server, while the WAS V5 client is bundled w/ the base product (essentially, it's the old MA88 support pac). If the WAS V5 client will provide us w/ what we need, we can save a boatload of $$$.
Anyone have any experience or information on this topic? I'd be REALLY grateful for ANY info !
Cheers, Art
