2.1. Environment Configuration

This section describes the environment configuration required to start WebAdmin, and how to start and shut down WebAdmin using the console tool.

Environment Configuration

To start WebAdmin when starting JEUS, the <enable-webadmin> element in the domain.xml file must be set to true.

[Example 2.1] WebAdmin Configuration - <<domain.xml>>

<domain xmlns="http://www.tmaxsoft.com/xml/ns/jeus" version="7.0">
   ...
   <admin-server-name>adminServer</admin-server-name>
   <group-communication-info>
      <heartbeat-address>230.30.1.1</heartbeat-address>
      <heartbeat-port>3030</heartbeat-port>
   </group-communication-info>
   <enable-webadmin>true</enable-webadmin>
   <servers>
   ...
</domain>

Permission Setting

A user must be granted the AdministratorsRole role in the policies.xml file to log into WebAdmin.

[Example 2.2] Permission Setting: <<policies.xml>>

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<policies xmlns="http://www.tmaxsoft.com/xml/ns/jeus">
    <policy>

Starting and Shutting Down WebAdmin Using the Console Tool

By default, WebAdmin starts when Domain Administration Server (DAS) starts. WebAdmin can be started and shut down using the console tool, jeusadmin, by following these steps.

  • Starting WebAdmin using the console tool.

    Execute the enable-webadmin command to start WebAdmin. For detailed information about the command, refer to JEUS Reference Book. "4.2.3.18. enable-webadmin".

    [Example 2.3] Starting WebAdmin Using jeusadmin

    [DAS]domain1.adminServer>enable-webadmin
WebAdmin was successfully enabled.
The configuration was changed.

JEUS WebAdmin provides a configuration lock feature for a specific user, not for a session. Only the user who has the lock can change the configuration.

The user has the lock until the user clicks [Apply Changes] to apply the changes or [Undo All Changes] to revert the changes. As long as the lock is not returned, the user can continue editing even if the user logs out and logs back in again.

Acquiring the Lock

The lock is not automatically returned. If the user does not return the lock, other users cannot make changes. To prevent this from occurring, other users can forcibly acquire the lock as in the following example.

  1. A user, user1, logs in and acquires the lock by clicking [Lock & Edit]. The user does not apply or revert the changes, and logs out while still in the Lock & Edit mode.
