The installer maintains an installation registry. The registry location depends on the platform. The files have
vpd as a prefix, which stands for Vital Product Database.
The installer launcher first extracts a Java Virtual Machine (JVM) in a temporary directory and uses this JVM to launch itself. The size of the extracted JVM differs from platform to platform.
If your system does not have sufficient free disk space in the above temporary area, you can still run the installer with a different temporary area using the following option when starting the installer:
where /new_tmp has sufficient free disk space.
When a regular (non-root) user installs a TIBCO product on UNIX platform, the installation registry (two vpd files) is maintained in the user's home directory. As more products are installed, entries are added into these vpd files.
The installer and uninstaller creates a file called _env.xml in the same location where the installation registry is created. Each time an installation and uninstallation is performed, entries are appended to the file.
The file _env.xml therefore contains the record of all installation and uninstallation activities of all products, features, and components.
