5.2.2 Prerequisites for a physical host environment
The following conditions are the prerequisites for operating JP1 in a physical host environment. If you only execute JP1 in
a logical host environment, the following prerequisites must also be satisfied as the system environment.

Prerequisites
|
|
Server
|
-
A cluster must consist of two or more servers.
-
The CPU performance must be sufficient for the processing to be performed.
(For example, the CPU must be able to handle the startup of multiple logical hosts.)
-
The real memory capacity must be sufficient for the processing to be performed.
(For example, the servers must have sufficient memory capacity to handle the startup of multiple logical hosts.)
|
|
Disk
|
|
|
Network
|
-
Communication must be enabled using an IP address corresponding to the host name (result of the hostname command).
(Clustering software or other programs must not modify the state to prevent communication.)
-
The correspondence between the host name and IP address must not be modified while JP1 is running.
(The correspondence must not be modified by clustering software or a name server.)
|
|
OS and clustering software
|
-
The clustering software and its version must be supported by JP1.
-
All patches and service packs required by JP1 and the clustering software must have been applied.
-
The same environment must be set up for all of the servers so that the same processing can be continued after a failover occurs.
