I have a Windows 7 / OpenEdge 11 Client and would like to read / write to a 9.1C Progress Database?
I would like to run a procedure on an appserver (output dataset-handle ...) that would define a data-source, attach to a Progress 9.1C db, and run my fill and save procedures.
Is this possible?
Your best chance might be using an OpenEdge 10 AppServer that can connect to the V9 DB.
I'm pretty sure, that an V11 client cannot connect to a V9 AppServer. The protocol became incompatible somewhere around the 10.1A clients or so.
So I'd try to connect from V11 to a rather recent OE10 AppServer that's connected to a V9 DB.
Let me know if that works.
Sorry, but an OpenEdge version 11 4GL program (whether client or app server agent) cannot connect to a version 9 database server. We have always supported database connectivity from a new release to one major release back (e.g. 10 to 9, 11 to 10, 8 to 7, etc.) and only via TCP (not in single user or self serving mode).
