Console takeover and recovery

The console takeover and recovery function allows an Operations Console to take control of another console device.

The console takeover and recovery function included in i5/OS^® allow an Operations Console to take control from another console device. The actions involved are:

Takeover

The process used for a LAN-connected, console-capable device to take control from the current LAN-connected console device. This takeover action cannot be used with local consoles that are directly attached or any other console type such as the twinaxial console.

Recovery

The process of regaining control of the job running on the console after a problem with the console is encountered. The recovery process might be to the same console device or a different console-capable device, and might require additional work to enable a device using a different connectivity, except a twinaxial console. The recovery function remains running as if nothing has happened. The twinaxial console uses a different type of 5250 emulation so even though you can use it to recover from or to, there is loss of data in the process.

Benefits of these functions include convenience and redundancy. Console-capable devices can be placed around a site, or multiple sites, allowing users to move around and gain control of the system from any of these devices. Whatever the previous console's activity was, the new console is at the identical place, even during the process of restarting the server or installing i5/OS. When the console option for takeover is enabled, the server also has enhanced recoverability from a loss of the console.
