We had a similar request last year. SAG’s response regarding a JDBC to RDB connection is below.
“Our customers of GCS implementation were successful in connecting to RDB (v7.2-321 on OpenVMS-Alpha v8.3). Unfortunately, we have not comes across successful results. There was only one customer who tried and was not able to connect. Sorry, that RDB (v7.2-321 on OpenVMS-Alpha v8.3) is not supported.”
I didn’t receive any information regarding the “customers of GCS” that were successful.
We are looking at an MQ Series solution instead. There maybe an option with a Java service, but very unlikely to be a viable solution in our environment.
