Secondary-center options
- Hot backup
- A secondary data center already operational and available for immediate switch-over
- Warm backup
- A secondary data center, possibly operational, available for switch-over after some delay (measured in hours or days)
- Cold backup
- A secondary data center with little or no equipment installed
- Pooling
- A secondary data center or cold site shared by several users (or subscribers).
- Physical transportation of data on media (tape, paper)
- Telecommunication lines
- Channel-to-channel connections
- Fiber-optic channel extenders.
If you have shared DASD with the secondary center either through channel-to-channel connectors or fiber-optic channel extenders, you can recover HCL Workload Automation for Z to point-of-failure by using the dual job-tracking facilities of HCL Workload Automation for Z.
Unless your secondary center is a hot backup that exactly mirrors your primary data center, you must identify the HCL Workload Automation for Z configuration needed to support the environment. With your system programmer, identify the HCL Workload Automation for Z subsystems required.
