Server instances

When you install a specific Communication Driver on a computer, a server group and default server instance are automatically created in the OI Server Manager. The Operations Integration Supervisory Servers folder, with its hierarchy of server groups and server instances, is shown only when you browse the Local node. Each server instance has its own configuration and diagnostics, can be activated and deactivated separately from all other server instances, and appears as a separate application to external clients. Newer Communication Drivers that have been optimized for Operations Integration support multiple server instances, which means that you can create additional server instances, and even clone existing server instances in those server groups. To enable multiple server instances, you must have a Professional (Tier 2) or Premier (Tier 3) license for Communication Driver.

The name of the default server instance is based on the short name of the Communication Driver itself. For example, for the Simulation Communication Driver, the default server instance is named OI.SIM.1. All server instance names follow this basic format. The middle part of a server instance name becomes the application name that external clients will use to access Communication Driver data. For example, if a server instance is named OI.SIM_0001.1, the corresponding application name will be SIM_0001.

Note: All of the server instances on a remote computer are listed together, regardless of their server groups.
