Switching is commonly used to maintain high availability and prevent unplanned downtime. Planned switches can also be performed for system maintenance, backups, or for workload balancing.
Note: Planned and unplanned switching is not supported in environments licensed for Assure MIMIX DR.

Two features of MIMIX can assist you with switching in a MIMIX environment:

  • Switch definitions for automating and customizing switching.  Switch definitions  permit the customization of your switching environment. Switch definitions identify the participating systems, the devices, applications, or TCP/IP addresses to be switched, and an event program containing your customized switching program.  A group monitor associated with the switch definition provides the capability of defining multiple events that will participate in the decision to switch.

  • MIMIX Model Switch Framework. In environments configured with only data groups, the MIMIX Model Switch Framework provides a consistent framework for performing planned or unplanned switches through a set of commands and programs. MIMIX Model Switch Framework is the basis on which simplified switching user interfaces for  data groups that do not belong to an application group operate. Typically, a Certified MIMIX Consultant assists you in setting up the programs and the switching environment. MIMIX Model Switch Framework cannot be used to swich application groups.

These features can be used individually or in combination. For example, a switch definition can be defined to a MIMIX Model Switch Framework. The switch framework processing will handle initiating switching for the hardware or IP impersonation defined by the switch definition.

Optionally, the SETSWTSRC command for the switch definition can be performed by the MIMIX Model Switch Framework event program. If this case, do not specify the switch definition for the Switch definition (SWTDFN) parameter when creating the switch framework definition with the CRTSWTFWK command.
