5.1 System environment settings

Network, load balancing, and operation automation settings are system environment settings that need to be specified. This section covers points to note when specifying network settings, settings for the different types of load balancing (hardware load balancers, and software load balancers), and the automation of (creating a job for) operations by using JP1/AJS3.

Points to note when specifying network settings

Important note

Disable the firewall idle communication watch functionality because the functionality might lower communication speeds between Application Server and the database when the functionality is enabled.

If the idle communication watch functionality is enabled, communication speeds might be lower than when connections reserved on the connection pool are used. This is because database connections reserved on the connection pool are disconnected by the idle communication watch functionality, and a new connection is required every time Application Server operates the database.

Load balancing settings

When using a hardware load balancer

Specify the setting for request distribution to Application Server and the setting for session maintenance on the hardware load balancer. For details about how to specify the settings, see the manual of the hardware load balancer in use.
- For configurations where the domain administration server and the runtime environment are set on different hosts
  
  Specify the request distribution settings only for Application Server on the created remote host. Do not specify request distribution settings for the domain administration server host.
- For configurations where the domain administration server and the runtime environment are set on the same host
  
  Specify request distribution settings for the domain administration server host.
When using a software load balancer

Configure load balancing by creating a web server on a remote host node and creating a dependency relation between the local host and the cluster on the remote host.

Automation of operations by using JP1/AJS3

Define the processes of starting and stopping Application Server , checking operation status, and collecting operation information and failure information as jobs, and then register them to JP1/AJS3. You also need to create a batch program to check operation status, and collect operation information and failure information.
