The silent installer is a Java program. The installation CD contains a sample batch file to run the install with the correct JRE and CLASSPATH settings. An additional text file specifies the installation type and options. These instructions assume that you will include the EAServer install files and customized installer scripts with the install media for your own software.
Configuring the silent installer
Create a directory for your install image.
Copy the following files from the EAServer installation CD to your install image:
EAS520.jar
readme.htm (Optional. If you are installing the HTML documentation, this file contains additional documentation).
libjinstaller.dll and msvcrt.dll
The JRE_1_4 subdirectory and its contents. Sybase recommends that you use this JRE to run the install. Other JRE versions may not work as well.
If you have the Developer or Workgroup Edition, copy SYBASE_EAS.lic from the root directory of the EAServer CD to the root directory of your install image.
If your silent install will upgrade an earlier EAServer installation, copy the following files and directories, preserving the relative path structure:
The SupportGeneric/Upgrade directory and contents
The SupportNT/Upgrade directory and contents
Create configuration and run files as described in “Configuration and run files”. Copy any required additional files from the EAServer CD to your install image, as described in that section.
To support the silent uninstallation process, create the files described in “Silent uninstaller files”.
Preserving the vpd.properties file
You may make a few errors when creating and testing your silent
install. Cleanup of failed installations requires that you delete
the InstallShield vpd.properties file. This
file may be required by the installers for other applications. Before
testing your install, back up the following file and restore it
before installing or upgrading other software:
%SYSTEMROOT%\vpd.properties
Testing and running the silent installer
Before running a silent installation, make sure you:
Have enough space in your temporary and product directories. See “System requirements”.
If your %SYSTEMROOT% directory contains an InstallShield vpd.properties file, make a backup copy.
For all upgrades, stop EAServer applications such as “Jaguar CTS” console server windows, EAServer Manager, and application servers that run as Windows services.
Test the silent installer using the run script that you created at the command line or in your own product’s installation script. Running a silent installation takes 10 – 20 minutes, depending on the speed of your computer.
After each trial run, check for errors, and clean up your machine as described in “Troubleshooting and cleanup of the silent installer”.
