Sun Cluster 2.2 Release Notes Addendum

Configuring Sun Cluster Manager

You can run Sun Cluster Manager (SCM) as a stand-alone application or through Netscape(TM) or HotJava(TM) browsers. To configure SCM to run with Netscape 4.5, use the procedures documented here. To run SCM with HotJava, use the procedures documented in the Sun Cluster 2.2 Release Notes. To run SCM as a stand-alone application on a cluster node or client workstation, use the instructions documented in the README file associated with the SCM patch (107388). Patches are available through your service provider or through the SunSolve web site at http://sunsolve.sun.com/

How to Run the SCM Applet in a Netscape Browser From a Cluster Node
  1. Install Netscape 4.5 on the cluster nodes.

  2. Install SCM and the required SCM patch on the cluster nodes.

    To install SCM, use scinstall(1M). The scinstall(1M) command installs the SCM package, SUNWscmgr, as part of the server package set. To get the SCM patch, see your service representative or the SunSolve web site:

    http://sunsolve.sun.com/

  3. Add the following lines to the preferences.js file, if necessary.

    The file is located in the $HOME/.netscape directory. If the preferences are not included in the file already, add the following lines:


    user_pref("security.lower_java_network_security_by_trusting_proxies", true);
    user_pref("signed.applets.codebase_principal_support", true);

  4. On a cluster node, set your DISPLAY environment variable so that the Netscape browser is displayed remotely on your X Windows workstation, and then run the Netscape browser on that cluster node.

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


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

  6. Click Grant on Java Security dialog boxes that ask for permission to access certain files, ports, and so forth from the remote display workstation.

    As Sun Cluster Manager comes up, you might see error messages similar to the following, at the tty that started the HotJava browser:

    File not found when
    looking for:
    netscape.security.PrivilegeManager

    These messages are prompted by the HotJava browser but do not affect Sun Cluster Manager running in the HotJava browser, because the files noted are available only through the Netscape browser.

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

How to Set Up Netscape to Run With SCM Using a Web Server
  1. Install a web server on all nodes in the cluster.


    Note -

    If you are running the Sun Cluster HA for Netscape HTTP service and an HTTP server on SCM, 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. Set security preferences by adding the following lines to the preferences.js file, if necessary.

    The file is located in the $HOME/.netscape directory. If the preferences are not included in the file already, add the following lines:


    user_pref("security.lower_java_network_security_by_trusting_proxies", true);
    user_pref("signed.applets.codebase_principal_support", true);

  4. Run the Netscape browser from your workstation.

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

    For example, if you had created a link from the web server's document_root directory to the /opt/SUNWcluster/scmgr directory, you would enter the following URL, where clusternode is the name of the physical host:


    http://clusternode/scmgr/index.html
    

  6. Click Grant on Java Security dialog boxes that ask for permission to access certain files, ports, and so forth from the remote display workstation.

    As Sun Cluster Manager comes up, you might see error messages similar to the following, at the tty that started the HotJava browser:

    File not found when
    looking for:
    netscape.security.PrivilegeManager

    These messages are prompted by the HotJava browser but do not affect Sun Cluster Manager running in a HotJava browser, because the files noted are available only through the Netscape browser.
