To Install the Load Balancing Plug-in (standalone)

Use the procedures in this section if the load balancing plug-in is not part of the GlassFish Communications Server distribution you are using.

The load balancing plug-in is not currently bundled with the GlassFish v2GlassFish Communications Server. If you want load balancing capabilities, you can download the load balancing plug-in from the following locations:

• Solaris (SPARC): http://download.java.net/javaee5/external/SunOS/aslb/jars/

• Solaris (x86): http://download.java.net/javaee5/external/SunOS_X86/aslb/jars/

• Linux: http://download.java.net/javaee5/external/Linux/aslb/jars/

• Windows: http://download.java.net/javaee5/external/WINNT/aslb/jars/

• Mac OS: http://download.java.net/javaee5/external/Darwin/aslb/jars/

1. Before you install the load balancer plug-in, ensure that you have installed a supported web server. For a list of supported web servers, see Web Servers in Sun GlassFish Enterprise Server v2.1.1 Release Notes.

   Ensure that you have exported the certificate required during installation. For details, see TBDlink.

2. Create the lbplugin directory within <glassfish_install_dir>/lib.

3. Unjar this file in the lbplugin directory. Run the following command: jar -xvf <lbplugin>.jar.

4. Unzip the following two files: SUNWaslb.zip and SUNWaspx.zip in the same directory. Delete the zip files.

5. Change permissions on all shared libraries within lbplugin directory. Run the following command: chmod -R 755 ${glassfish.home}/lib/lbplugin/lib.
