This chapter describes the menus of WebAdmin and how to use them.

2.1. System Search/Control

In [System Settings], you can check the current WebtoB configuration and connected client information. This is similar to using the wsadmin config command. For more information about the command, refer to WebtoB. "6.1.1.2. config (cfg)".

Click [Node] from the navigation pane to display the list of nodes.

[Figure 2.1] Viewing a WebtoB Node in WebAdmin

Click a node name to display more information about the node. For information about each item, refer to WebtoB. "3.3. NODE Section".

[Figure 2.2] Viewing Node Information in WebAdmin

Note

You can view information about each system component. For information about individual settings, refer to WebtoB. "Chapter 3. Environment Configuration".

Dynamic Settings

Some settings can be changed dynamically. Settings that can be changed dynamically do not require restart of WebtoB. Dynamic configuration changes have the same effect as using the wsadmin set command. For more information about using this command, refer to WebtoB. "6.1.5.1. set".

Click [Dynamic Configuration] at the top left to open the following window:

To change an item, enter a value and then click [OK] to apply the changes.
