The registry stores the Oracle configuration parameters. This appendix
describes only the configuration parameters that apply to Oracle client
products on Windows NT.
Oracle8 Client software uses configuration parameters to locate files
and specify runtime parameters common to all Oracle products. When an Oracle
program or application requires a translation for a particular configuration
variable, Oracle8 Client consults the associated parameter. Oracle parameters
are stored in the registry.
Registry
Overview
Oracle8 Client stores its configuration information in a database (the
registry) that is organized in a tree format. The tree format consists
of keys in the registry and parameter values for the keys. Keys and parameter
values can be viewed and modified in the Registry Editor.
Keys are folders that appear in left pane of a Registry Editor
window. A key contains subkeys or parameters.
ATTENTION:
The Registry Editor allows you to view and modify registry keys and
parameter values. Normally, you do not need to do so, and in fact, are
liable to break your system if you make incorrect changes.
Parameters in the Registry Editor appear as a string that consists of
three components:
name of the parameter
value class or type of entry
value itself
For example, parameter ORACLE_HOME has the following entry in the registry:
ORACLE_HOME:REG_EXPAND_SZ:ORCL
Value classes for Oracle8 Client parameters are:
string value with a REG_SZ, REG_EXPAND_SZ (for
an expandable string), or REG_MULTI_SZ (for multiple strings) prefix to
identify parameter value entry as a data string
binary value with a REG_DWORD prefix to identify
a value entry as a DWORD (hexadecimal data) entry

From the command prompt, enter:
C:\>REGEDT32
Choose Start>Run, enter REGEDT32
in the Open field, and choose OK.
The Registry Editor window appears:
Navigate to the values you want to view or modify
by double-clicking keys.
The left-hand side of the windows shows the hierarchy of registry keys,
and the right-hand side of the window shows various values associated with
a key:
