Creating a PAS for OpenEdge instance involves defining a name and location for the instance as well as defining various configuration properties.

With the development mode of PAS for OpenEdge, a default instance, oepas1, is created in your work directory. However, a default instance is not created when you install a production version of PAS for OpenEdge. A default instance would mean that ports, name spaces, and other values that are well-known would be exposed, and having well-known values is a security risk. Therefore, before you deploy an application to PAS for OpenEdge, you must create an instance.

Note: Never use a PAS for OpenEdge instance created in development mode in a production environment. Use only PAS for OpenEdge instance created in production mode for deployment in public facing production environment.

When you create an instance, the properties of the instance are automatically set to the directory where the new instance is created and the related files and logs are stored. The following properties are set when the new instance is created and can be controlled by the system administrator:

  • The environment variables and paths for running commands
  • The HTTP and HTTPS transports, and ports
  • The username and password for the instance
  • The type of instance (development or production)
