6.6.50: Administering coexisting product versions and editions

Coexistence of Standard and Advanced Editions of Application Server

Running Standard Edition and Advanced Editions on the same machine is not supported. Simultaneous use of a Web server by both editions (trying to install the Standard Edition and Advanced Edition WebSphere plug-ins on the same Web server instance) is not supported.

Coexistence of Advanced and Enterprise Editions of Application Server

The Enterprise Edition and Advanced Edition can run on the same physical server provided you perform some configuration steps:

  1. Resolve port conflicts. Configure Advanced Edition to use a bootstrap (Location Service Daemon) port number other than the default of 900.
  2. Resolve ORB differences by prepending the classpath with the Enterprise Edition ORB.

    Add classpath statements to the application servers in Advanced Edition:

    -classpath <somcbase>/lib/somojor.zip;%classpath%
    where somcbase is the base installation directory of the Enterprise Edition ORB.
  3. Edit the adminclient.bat file in:
    product_installation_root/bin
    Have it point to the port number you configured in admin.config.

Coexistence of Versions 2.0x and 3.x of Application Server

IBM WebSphere Application Server Versions 2.0x and 3.x can exist on the same machine, but it is not recommended. If 2.0x must reside on a machine with Version 3.x (3.0x or 3.5), make sure each is associated with a separate Web server. Also, make sure they do access the same resources, such as ports and files. Finally, be alert to problems stemming from using two different versions of the JDK and other prerequisites on the same machine.
