If you need to know what Oracle software components are installed on your
system you can open either the NT.rgs or WIN95.rgs file (depending on which
version of Windows you are using). The .rgs file is a text file that
contains information about what Oracle components are installed on the
system. The file looks similar to the following:
0 ntinstall all "orainst" "3.3.1.0.0C" "Oracle Installer"
20 w32tcp80 adp80 "tcp80" "8.0.5.0.0" "Oracle TCP/IP Pro
23 w32nmp80 adp80 "nmp80" "8.0.5.0.0" "Oracle Named Pipe
26 w32util80 all "util80" "8.0.5.0.0" "Oracle8 Utilities
34 w32rsf80 all "rsf80" "8.0.5.0.0" "Required Support
47 w32netclt80 net80 "netc80" "8.0.5.0.0" "Oracle Net8 Client
69 w32plus80 all "plus80" "8.0.5.0.0" "SQL*Plus"
There is a lot more information than what you see in the preceding display.
The additional information includes when the installation of the components
took place and a detailed description of the component.
The .rgs files (both NT.rgs and WIN95.rgs) are found in the \ORAINST
directory off the Oracle home directory. The location of the Oracle home
directory is dependent on which drive you install Oracle on and what
operating system you use. For example, the Oracle home directory for a
Windows NT installation on drive C:\ would be as follows:
C:\ORANT
Therefore, the path for your .rgs file on this installation would be:
C:\ORANT\ORAINST\NT.RGS
