I have Openegde database and Oracle 11g DB , What connector should i use ??
This depends on what application you are using.
If you have a java based application, you should install the Connect for JDBC driver which includes connectivity to Oracle 11 and OpenEdge 10.1x, 10.2x and 11.x.
In case the application is ODBC based, you can download the Connect for ODBC driver. This driver also includes connectivity to Oracle 11 and OpenEdge 10.1x, 10.2x and 11.x.
More information can be found on www.progress.com/datadirect-connectors
You can click on this page on 'Oracle Database' and 'Progress OpenEdge' to see what drivers are available.
You will notice we have an ODBC and JDBC driver for both.
OData and Cloud solutions are also available.
Let me know if you have further questions.
