The TIBCO product installer maintains the registry information in the vpd.properties.tibco.system_name file. The value for
system_name is determined by
InetAddress.getLocalHost().getHostName(). However, the method
getHostName()returns different values based on the JRE versions used. For example, on AIX, JRE 1.3.1 returns only
system_name, whereas JRE 1.4.0 returns
system_name.domain_name. Because of this, the installer is not able to load the correct registry file.
On Unix platforms, the installer registry file vpd.properties.tibco.system_name is located in the user's home directory.
