Oracle Database Discussions

1. Create a directory to be used for the Oracle Net configuration files, and set
the TNS_ADMIN variable to point to this. It doesn’t matter where the direc-
tory is, as long as the Oracle user has permission to create, read, and write it.
On Linux:
mkdir /u01/oracle/net
export TNS_ADMIN=/u01/oracle/net
Ensure that all work from now is done from a session where the variable has
been set.
On Windows:
mkdir d:\oracle\net
Create and set the key TNS_ADMIN as a string variable in the registry in
the Oracle Home branch. This will typically be
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraDb1g_home1

OK...in my little window CLI window I did the mkdir. HOW..HOW do I create and set the key TNS_ADMIN as a string variable. I have tried a few ways but I don't think i am doing it correctly. Please help.
