Sun Java Enterprise System 5 Installation FAQs for UNIX

What to Do After Installation

This section contains questions about how to proceed after installation if verified.

Q31: How do I install more components on a host after I've already done an installation?

Answer: To install additional components, run the installer again. The installer surveys the host to find any installed Java ES components. If the installed component versions are correct, the installer uses the installed components to satisfy the dependencies and requirements for the additional components you are adding to the host. Any version-compatible components that are already installed are not available on the selection page of the installer. For example, you have installed Access Manager and its required components. In a later installation session you decide to install Portal Server. The installed instance of Access Manager is the correct Java ES version, and so is used to meet the Portal Server dependency on Access Manager. You are not asked to install Access Manager again.

Note –

When adding components to a host where a Java ES installation has already been done, you will need to specify the correct paths and passwords if the new component depends on a component that is already installed and configured. If you do not remember the paths or passwords, refer to the Installation Summary for the original installation before you add any components to the host. Default installation directories and ports are listed in the Chapter 2, Default Installation Directories and Ports, in Sun Java Enterprise System 5 Installation Reference for UNIX.

Q32: How do I start using the Java ES components after installation?

Answer: After you have installed and verified the Java ES components, you can refer to the documentation for a particular Java ES 5 component. If you are a new user, look for introductory or getting started material for the product component. This information is often in a document called technical overview.

Q33: If I did an evaluation installation, can I reconfigure the evaluation installation to create a production environment?

Answer: No, reconfiguring your evaluation installation does not usually result in a viable production deployment. Instead, do the following:

  1. Remove your evaluation installation of Java ES using the uninstaller. See Chapter 8, Uninstalling, in Sun Java Enterprise System 5 Installation Guide for UNIX.

  2. Examine the product registry to verify that all of the Java ES files from the previous release have been removed. See Q40: What is the product registry and why should I care about it?

  3. Examine your host files to verify that no Java ES packages are present.

  4. Install your production deployment on multiple hosts based on your formal deployment and installation plans. See Q6: How much planning do I need to do before I install Java ES?
