5.1 Installation and design procedures
This section describes the decisions that you must make according to the jobs your system will process before you evaluate the considerations on the installation of HA Monitor.
Determine the following beforehand:
-
Jobs for which a hot-standby configuration is to be applied
Your hot-standby configuration will be determined by the number of jobs that are to be handled in the configuration.
-
Level of reliability and performance needed
-
Programs used for the jobs
The monitoring method used by HA Monitor depends on the types of programs.
-
Type of resources needed by your programs
The following describes the considerations and the decisions to be made based on this information before you install HA Monitor.
