Connecting to a AIX DB2 7 from WebSphere for OS/390 or DB2 OS/390

| Hello,
I've a question concerning connecting to a AIX DB2 7 from a WebSphere
for OS/390 V4 application server. Today the application server only
connects to a local DB2 7 on the same LPAR. But now we have to
integrate a database running on AIX.
We understand that with the standard DB2 V7 for OS/390 JDBC-Driver a
remote connection to a AIX database isn't possible. So we thought
about using the DB2 V8 Type-4 JDBC-Driver additionally. But we think
that isn't possible, too, because
- In the WebSphere for z/OS documentation we found the note, that
coexistence between the db2j2classes.zip (old driver) and db2jcc.jar
(new type 4 driver) isn't possible. Additionally we don't think that
it's possible to connect to a DB2 V7 with the DB2 V8 driver.
- In the document "Assembling Java™ 2 Platform, Enterprise Edition
(J2EE™) Applications" in chapter 16 we found the note that with any
type 4 JDBC-driver two-phase-commit-protocol isn't supported. We need
2PC.
It's hard to believe that a connection is not possible. We also
thought about integrating the two databases on the database tier with
the "distributed data facility" of DB2 V7 for OS/390. But we did not
found a clear statement in the documentation if this is possible.
Additionally we came across RmiJdbc (see
http://rmijdbc.objectweb.org/). Has somebody experience in using this
open source product, especially on OS/390 and with two-phase-commit?
Thank you very munch in advance and kind regards,
Frank

| I believe that the StarSQL for Java JDBC driver should allow you to do what
you want, but you'd better check that directly with the vendor
(www.starquest.com). It does support 2PC.

| Configure the Local DB2 on OS/390 communication database to connect
to DB2 UDB on AIX. Once done, you should be able to access the DB2
on AIX as if it was local.
