What to consider |
Explanation |
|---|---|---|
|
1 |
The work tasks to which disaster recovery should apply |
Determine the work tasks running in JP1/AJS3 that you want to resume operation on the remote site immediately after the site has stopped because of a large-scale disaster, and determine whether disaster recovery should be used. |
|
2 |
The disaster recovery post-recovery processes |
Determine a site on which work tasks should be resumed if the main site stops. Also determine whether to continue to run the work tasks whose operation has resumed at the remote site or return their operation to the original site. |
|
3 |
The hosts, OSs, and programs to be prepared |
Check the system prerequisites, and examine the computers, OSs, and programs, such as JP1/AJS3 - Manager, required for each site. For details about the prerequisites for disaster recovery, see 11.1.2(1) Prerequisites in the JP1/Automatic Job Management System 3 Administration Guide. |
|
4 |
The conditions for using the system |
