Oracle Database Discussions

Is there any possibility to gain information about the currently used Oracle Home
from the Windows Registry (XP SP 2) without knowing the oracle home, that is given during installation?

I have just found the following entry:

HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraDb10g_home1

This is correct and the only Oracle version that is installed at the system.

Unfortunalety the Key is build up from the Home-name specified during the installation, and i don't have that information when i need it.

I need to get the ORACLE_HOME from a windows registry without knowing the exact key name. Something like

HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\Key_Current_Oracle_Home.

But i havent't found anything like that.

Thx,
M.
