Hardware
You can run the Clarion development environment on any system that meets the minimum system requirements for Microsoft Windows (all versions).
Software
To develop Windows programs with Oracle Accelerator, you must have Oracle version 7.0 or higher.
The minimum configuration is to install the Oracle Instant client, which would contain the following DLLs:
OCI.DLL
oracnnzsbb11.dll
oraociicus11.dll
These files reference version 11. One other file is required if you are using non-Western languages.
These .DLLs must be in a directory that is in your system PATH.
You will not be able to define or import Oracle files in your Clarion data dictionary until the Oracle DLLs are installed in a directory that is in your system PATH.
The Oracle driver requires that you have a valid Oracle client installed on both the development and user machines. Oracle clients come in two versions: a regular client and an “Instant” client. The regular client supports TNSNAMES (see Oracle documentation). The Instant client requires you to specify full connection parameters to the Oracle server (IP address, Port, SID (Server ID)), but is much smaller and easier to deploy.
