Server Configuration
Use
This section describes how the structure of the server configuration is displayed in the Config Tool.
Features
The current server configuration is scanned from the database to which you have connected and displayed in the main frame as a tree structure. The root element of the tree is the J2EE Engine cluster. It contains:
· A global dispatcher configuration and a global server configuration
Contain the global service and manager properties for each module. Changing these properties reflects to all cluster elements. The global properties include default and custom values. You cannot change the default values, you can set a custom value instead and it will be valid only if there is not a local value (default or custom) for this property.
The priority of the property values is as follows (in decreasing order): local custom value, local default value, global custom value, global default value.
For more information about local and global
properties, see
Global and Local
Properties in the Architecture Manual.
· All instances listed
Each instance contains one Java dispatcher and a specified number of server processes (the number is specified during the installation time of the J2EE Engine). Each module contains a list of managers and services, as each one of them presents its local properties. You can change them according to your needs.
The instance itself contains settings such as JVM parameters for server processes, debug settings, Message Server and Bootstrap settings that are relevant for all elements in the instance. Therefore, if you change an instance parameter, it will reflect to all elements in the instance. To set a different parameter value for a specific element, then you have to select this element and configure it separately. The new server processes will have the parameters that are set on the instance.
