The Registry configuration process installs the Registry database and server keystore in the following directory:
Solaris OS: /var/opt/SUNWsoar
Linux: /var/opt/sun/SUNWsoar
The directory is not removed when the Service Registry is uninstalled. This allows you to preserve the database for use in a future installation or release if you want To do so, copy the /var/opt/SUNWsoar/3.0 directory (on Solaris OS) or /var/opt/sun/SUNWsoar/3.0 (on Linux) to another location before you reinstall the Registry, then copy it back after you reinstall.
