8.9.2 Environment setup for running logical hosts in a non-cluster system (for UNIX)
This subsection explains how to run JP1/IM - Manager in a non-failover logical host environment.
- Organization of this subsection
(1) Preparing for a logical host environment
To create a logical host environment, provide the disk area and IP address for the logical host.
-
Disk area for a logical host
Create directories on the local disk for storing files that are used exclusively by the JP1/IM - Manager on the logical host. Make sure that these are separate directories from the directories used by JP1 on the physical host and other logical hosts.
-
IP address for the logical host
Use the OS to assign an IP address to be used by the JP1/IM - Manager on the logical host.
This IP address might be a real IP or an alias IP, but it must be uniquely identifiable from the logical host name.
The prerequisites are the same as for cluster system operation. However, conditions such as inheritance between servers are not applicable because the operation does not involve failover.
Where they appear in Chapter 7. Operation and Environment Configuration in a Cluster System (for Windows), replace the shared disk and logical IP address with the disk area and IP address for the logical host that were allocated above.
-
Estimating the performance
Evaluate the system operation in terms of the following:
-
Evaluate whether sufficient resources to run multiple JP1/IM - Managers in the system can be allocated. If there are not enough resources, the system might not run correctly or might not achieve an acceptable level of performance.
-
(2) Setting up JP1 in the logical host environment
Set up JP1 in the logical host environment using the same procedure as for the primary server in the cluster system. In the cluster system, this setup has to be performed for both servers involved in failover. For a non-failover logical host, you need to set up only the one server that will be running.
(3) Setting automatic startup and automatic termination in the logical host environment
The settings for automatic startup and automatic termination are not made in the logical host environment in the case of JP1 setup. To perform automatic startup and automatic termination in the logical host environment, see 3.3 Automatic startup and automatic stop setting examples when a logical host operates in a non-cluster system in the JP1/Integrated Management 2 - Manager Administration Guide.
