Resilient Hosting of OS 2200 Consoles

An OS 2200 console in a ClearPath Dorado Enterprise System is defined in a partition profile by Site Configuration and Management System (SCMS). Each OS 2200 console has a priority list of Operations Sentinel servers that can host the console. In this role, an Operations Sentinel server is referred to as an Operations Server.

When a partition profile is activated for an OS 2200 partition in the ClearPath Enterprise System, Server Control requests an Operations Server to host the OS 2200 console. One Operations Server can host multiple OS 2200 consoles, limited only by the capacity and performance of the Operations Server.

If an Operations Server fails, the OS 2200 Console Interface component of Server Control looks at the priority list associated with each OS 2200 console that was hosted on the failed Operations Server and requests the next Operations Server in the list to rehost the console. The OS 2200 console resumes its functions on the new Operations Server. The Operations Server that hosts each OS 2200 console can change over time. System operators and administrators can monitor which consoles are hosted on which Operations Servers using the OS 2200 Console Manager application that is provided in Operations Sentinel.

If a Service Processor fails, its functions automatically switch to the standby Service Processor, preventing the loss of OS 2200 console communication with Operations Sentinel servers.

If the Operations Sentinel workstation on which an operator is running OS 2200 Console View fails, the operator can launch OS 2200 Console View from another available Operations Sentinel workstation. However, if an Operations Server fails and the OS 2200 console is rehosted to another Operations Server, the connection switches to the new Operations Server automatically. The operator can continue using the same OS 2200 Console View window for managing the OS 2200 console.
