MIMIX provides a customized implementation of MIMIX Model Switch Framework to perform a switch. MIMIX Model Switch Framework is ideally suited for customizing a switching solution that detects the need for an unplanned switch, switches the direction of data group replication, and switches users to the backup system. Typically, if you have a Runbook, it will direct you when to use your MIMIX Model Switch Framework implementation for both planned and unplanned switches.
The MIMIX Model Switch Framework calls the Switch Data Group (SWTDG) command. The SWTDG command only switches the direction in which replication occurs for a single data group; it does not switch users or any other facets of your normal operating environment to the backup system. However, MIMIX Model Switch Framework can be configured to address these additional facets of your environment for multiple data groups. If you choose to use the SWTDG command either by invoking it from a command line or by using the options for switching on the Work with Data Groups display, you must take action to switch users to the backup system and address other requirements for operating there.
The switching option from the MIMIX Basic Main menu are implementations of MIMIX Model Switch Framework. The implementation is identified within policies.
Instructions for switching using MIMIX Model Switch Framework are described in Switching a data group-only environment.
