Sun Cluster 2.2 System Administration Guide

2.6 Running the SCM GUI in a HotJava Browser

The following set of procedures outline what you need to do to run SCM in a HotJava browser.

You may need to determine if you have the correct version of the following:

Note -

If you choose to use the HotJava browser shipped with your Solaris 2.6 or 2.7 Operating System, there may be problem when using the menus, for example: after making your menu selection, the menu selection can remain visible on the browser. Refer to the Sun Cluster 2.2 Release Notes for complete information based on your software requirement needs.

Refer to the Sun Cluster 2.2 Release Notes for complete information on software requirements.

You will need to determine whether you want to:

Depending on what you decide, refer to the appropriate procedure.

2.6.1 How to Determine the JDK Version

    Type the following from the console prompt on the server in your cluster:

java -version

Refer to the Sun Cluster 2.2 Release Notes for complete information on software requirements.

2.6.2 How to Determine the HotJava Version

    From the machine running the HotJava browser, select About HotJava from the Help menu.

Refer to the Sun Cluster 2.2 Release Notes for complete information on software requirements.

2.6.3 How to Run the SCM Applet in a HotJava Browser From a Cluster Node

  1. Run your HotJava browser on a node in the cluster.

  2. Remotely display it on an X windows workstation.

  3. Set the applet security preferences in the HotJava browser:

  4. Choose Applet Security from Preferences on the Edit menu.

  5. Click Medium Security as the Default setting for Unsigned applets

  6. When you are ready to begin monitoring the cluster with SCM, type the appropriate URL.

    file:/opt/SUNWcluster/scmgr/index.html

  7. Click OK to dialog boxes that ask for permission to access certain files, ports, and so forth from the remote display workstation to the cluster node where the browser is started.

    Note -

    It may take HotJava some time to download and run the applet. No status information will appear during this time.

    Refer to the online help for complete information on menu navigation, tasks, and reference.

2.6.4 How to Set Up a Web Server to Run With SCM

If you choose, you can install a web server on the cluster nodes to run with SCM.

  1. Install a web server that supports HTML 2.0 or later on all nodes in the cluster.

    One option is Sun Web Server, which is available to download at http://www.sun.com/solaris/webserver.

    Note -

    If you are running the HA-HTTP service and an HTTP server on SCM, you need to configure the HTTP servers to listen on different ports. Otherwise there will be a port conflict between the two.

  2. Follow the web server's configuration procedure to make sure that SCM's index.html file is accessible to the clients.

    The client applet for SCM is in the index.html file in the /opt/SUNWcluster/scmgr directory.

    For example, go to your HTTP server's document root and create a link to the /opt/SUNWcluster/scmgr directory.

  3. Run your HotJava browser from your workstation.

  4. Set the applet security preferences in the HotJava browser:

    1. Choose Applet Security from Preferences on the Edit menu.

    2. Click Medium Security as the Default setting for Unsigned applets

  5. When you are ready to begin monitoring the cluster with SCM, type the appropriate URL.

    http://cluster node/scmgr/index.html

  6. Click OK to dialog boxes that ask for permission to access certain files, ports, and so forth to the cluster node where the browser is started.

    Note -

    It may take HotJava some time to download and run the applet. No status information will appear during this time

    Refer to the online help for complete information on menu navigation, tasks, and reference.
