4.4 Starting the Web-Based Admin View Screen

After completing all the preparations, start the Web-Based Admin View GUI screen.

Operation Procedure:

Startup from the command (recommended)
1. Press [Win] + [R] key on the client and the dialog box [Run] opens.
2. Input the javaws command with the format below and access to the cluster management server.
```
javaws http://<host-name>:<port-number>/
```
Startup from the Web browser (If using Java Web Start)
1. Startup the Web browser on the client.
2. Specify the URL with the format below and access to the cluster management server.
```
http://<host-name>:<port-number>/
```
3. When using Microsoft Edge browser, click [Open] at the notification bar of file download completion which is displayed at the lower part of the browser.
  When the notification bar of file download confirmation is displayed, click [Save] to save the file and then click [Open].
Startup from the Web browser (If using Java Plug-in)
1. Start the Web browser in the client.
2. Specify the URL in the following format, and access the cluster management server:
```
http://<host-name>:<port-number>/Plugin.cgi
```
  <host-name>
  The IP address or the host name (httpip) that clients use to access the primary or secondary management server.
  The default value of httpip is the IP address that is assigned to the node name that is output when "uname -n" is executed.
  <port-number>
  Specify "8081."
  If the port number has been changed, specify the up-to-date number.
  For instructions on changing the http port number, see "7.2.1 http port number" in "PRIMECLUSTER Web-Based Admin View Operation Guide."
  Note
  - If the Web-Based Admin View screen cannot be started when the host name is specified in <host-name>, specify the IP address directly that corresponds to the host name.
  - When specifying the IPv6 address for <host-name>, enclose it in brackets "[ ]".
    (Example: http://[1080:2090:30a0:40b0:50c0:60d0:70e0:80f0]:8081/Plugin.cgi)
  - Note that the access method may be different depending on the operation management product. To use operation management products that have different access methods at the same time, see "3.3.4 Concurrent use of operation management products with different access methods" in "PRIMECLUSTER Web-Based Admin View Operation Guide."
  - For information on the IP address or host name (httpip) used by clients, see "PRIMECLUSTER Web-Based Admin View Operation Guide."
  - When a URL is to be registered for the bookmark of a browser, register "Plugin.cgi."
3. When the Web-Based Admin View is started, the following window appears.
  Enter a user name and password that have been registered to the management server, and click OK.
  Note
  You cannot close this window by clicking <X> in the upper right corner.
4. When authentication ends, you can use Web-Based Admin View.

Note

After starting the Web-Based Admin View screen, do not change the page by pressing the Forward/Next, Back, or Reread/Refresh buttons.
The screen of some browsers may hang.
- If the browser is terminated, restart the browser and display Web-Based Admin View.
- Reread the URL or restart the browser if the browser does not work (no response).
- The operation can be continued after the Web-Based Admin View is started by moving the mouse on the browser if the page switches to a black screen.
If "Welcome to Web-Based Admin View" does not appear after you read the URL of the Java Plug-in with Internet Explorer, an appropriate Java Plug-in may not be installed. Confirm that an appropriate Java Plug-in is installed by using "Add/Remove Programs" in the control panel. If the Java Plug-in is not installed or if an older Java Plug-in version that is not supported is installed, see "PRIMECLUSTER Web-Based Admin View Operation Guide" and install the Java Plug-in. Also, if the "security warning" dialog box appears, and prompts you to specify whether the "Java Plug-in" is to be installed and executed, select No.
If the secondary cluster management server is set to operate dynamically, there is a function that connects automatically to the primary or secondary cluster management server that is operating at that time even if the URL of a specific monitoring node is specified. For details, see "7.4 Secondary management server automatic migration" in "PRIMECLUSTER Web-Based Admin View Operation Guide."
If repeated errors occur during the authentication of Step 3, the message 0016 may be displayed and you may not be able to log in. For the action to take if this happens, see the corrective action No.3 of "Symptom 16" in "B.1 Corrective action" of "PRIMECLUSTER Web-Based Admin View Operation Guide."
If some problems occur while you are using Web-Based Admin View, see "Appendix A Message" and "Appendix B Troubleshooting" in "PRIMECLUSTER Web-Based Admin View Operation Guide."
When starting the screen using Java Web Start from the Web browser, a downloaded file name may be something other than WebStart.jnlp.
When starting the screen using Java Web Start from the Web browser, a tab remains in the Web browser after starting Web-Based Admin View screen and the user name input screen. Closing this tab will not cause any problems because it does not operate with the Web-Based Admin View after starting the screen.
When starting the Java Web Start screen from the Web browser in an environment where the extended screen provided by the multi-display function of Windows is used, the screen may not start or the screen size may be reduced or expanded.
