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, there is no default instance created when you install a production version of PAS for OpenEdge. A default instance implies that ports, name spaces, and other values would be well-known and would result in a security risk. Therefore, before you can 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 related files and logs are stored. The following properties are set when creating the new instance 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)
