What is an instance?
An instance is basically a Windows service - Cadcorp GeognoSIS Manager allows you to administer instances/services. For eg your GeognoSIS can contain:
- One instance to serve Ordnance Survey base mapping,
- Another instance to serve business data using the GeognoSIS HTTP API.
- A third instance for a Cadcorp mapping product (eg WebMap 9).
When GeognoSIS is installed, an Administration instance is created and uses a port number. You can see this in GeognoSIS’s final installation screen.
In this example, port number 4600 is used and forms part of the URL for the browser-based GeognoSIS Manager.
Instances also allow resources and access to the GeognoSIS engine to be isolated from each other.
TIP: When separate instances are used for different services, sites or tasks, they run independently of each other. This in turn ensures stability and fair distribution of resources.
