Job Management Partner 1/Automatic Job Management System 3 Administration Guide
This subsection describes the configurations of cluster systems supported by JP1/AJS3.
- Organization of this subsection
- (1) Conditions for the system configuration
- (2) Examples of supported system configurations
(1) Conditions for the system configuration
A cluster system in which JP1/AJS3 operates must satisfy the following conditions:
- A logical host must have a shared disk and a logical IP address that can be passed from the primary node to the secondary node. The shared disk and logical IP address must satisfy the conditions shown in 11.1.1 Prerequisites for JP1/AJS3, and the scope supported by JP1/AJS3.
- All the hosts that make up the cluster system must use the same OS. A failover cannot be performed if they do not use the same OS.
- JP1/AJS3 - Manager and JP1/AJS3 - Agent cannot be installed on the same server.
(2) Examples of supported system configurations
(a) Active-standby configuration
The following figure shows an example of an active-standby configuration.
(b) Active-active configuration
The following figure shows an example of an active-active configuration.
(c) Three-node configuration
The following figure shows an example of a three-node configuration.
- Remarks on JP1/AJS3 operation in a cluster system that uses three or more nodes:
- JP1/AJS3 operates in a logical host environment managed by cluster software (with a shared disk and logical IP address). The operation does not differ depending on the number of nodes.
- There will be no particular problem with JP1/AJS3 operation in a cluster system consisting of three or more nodes, as long as the logical host environment is normally managed by cluster software.
