Connect DB in progress 9.1D with JDBC from OpenEdge 10.2B

[ByWolf]

Hello!
I want to connect one DB in Progress 9.1D with my installation of OpenEdge 10.2B in a linux Machine, but when i connect from sqlexp return "null" and with OpenEdge architecht the IDE hangs.

is there a problem with backward compatibility???

I'm already working with JDBC connections in OpenEdge, but I can't upgrade the DB in 9.1D because infrastructure reasons.

greetings.

AFAIK, you can't use a V9 database in OE Architect with the SQL connection. The reason is that there were huge changes in the database engine to make this possible. AFAIK, the SQL engine was completely overhauled for OE10.1A which first included the OE Architect.

One reason to have the SQL connection to the database in OE Architect is the usage of the DB Navigator which allows you to make schema changes. For simply developing 4GL programs the 4GL connection should be sufficient.
