IBM's DB2 Information Integrator (formerly know as DataJoiner) is a DRDA-->ODBC bridge like you describe.

IBM's product is the only DRDA-->ODBC bridge I know of.  Oracle's Access Manager product is a DRDA-->Oracle bridge and products such as RPG2SQL are a proprietary-->ODBC bridge.

Yep.  But it cost something like $25,000.

Actually, the best way I've seen it done is have a Java daemon waiting on SQL requests to be placed into a data queue.  Your RPG program adds a request to a data queue and waits for the Java daemon to place the results into another queue.

There was an article that used this technique in iSeries Network.  It was pretty basic, always sent the SQL to a particular SQL server.  But it wasn't hard to expand upon the original idea with multiple SQL and/or Oracle servers.
