The silent installer is a Java program. The installation disk contains a sample batch file to run the installer 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 installation files and customized installer scripts with the installation media for your own software.
Configuring the silent installer
Create a directory for your install image.
Copy the following files from the EAServer installation disk to the install image directory:
EAS620.jar
readme.htm. If you are installing the HTML documentation, this file contains additional documentation.
The JRE_1_5 subdirectory and its contents. Sybase recommends that you use this JRE to run the installer. Other JRE versions may not work as well.
The Modules/LicensePanel directory is required, as are the other files and directories in the Modules folder.
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”.
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 necessary, you can edit the shell script that runs the installer and change the temporary directory location specified for the -Dtemp.dir command line option.
If your home directory contains an InstallShield vpd.properties file, make a backup copy. If you run the installer with a different user ID, check for this file in the home directory of that user ID and back it up if it exists.
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”.
