Each OS 2200 console for a ClearPath OS 2200 partition is hosted on an Operations Server. For each Exec console, you can configure the precedence of Operations Servers for hosting it. See “Run Time Configuration.” A ClearPath Dorado Enterprise System can automatically rehost any OS 2200 console onto a different Operations Server if the one on which the console is running fails. After the console is rehosted, each instance of OS 2200 Console View that was connected to the OS 2200 console automatically reestablishes a connection with the console. Placing the Operations Servers on different networks provides network resiliency.

Reactivating a ClearPath OS 2200 partition that has active OS 2200 consoles associated with it, results in the loss of the retained variables maintained by the CP-AMS database activated on the OS 2200 consoles. This is because the procedure for the reactivation is similar to the procedure for deactivating and then activating the OS 2200 partition. After the partition is deactivated, it closes off all the consoles associated with it, which in turn deactivates the currently active database at the console, and flushes off the memory containing the variable group and retained variable values.

Following are the other circumstances under which the retained variables are lost:
