Parameter WALLET_LOCATN in file sqlnet.ora specifies the location of the obfuscated Oracle Wallet for use by Oracle PKI applications.
For example, the WALLET_LOCATN parameter for storing an Oracle Wallet in the registry in:
\\HKEY_CURRENT_USER\SOFTWARE\ORACLE\WALLETS\SALESAPP
is located in:
WALLET_LOCATN = (SOURCE= (METHOD=REG) (METHOD_DATA= (KEY=SALESAPP)))
Continuing the example, the encrypted Oracle Wallet is stored in the registry in:
\\HKEY_CURRENT_USER\SOFTWARE\ORACLE\WALLETS\SALESAPP\EWALLET.P12
and the changed Oracle Wallet stored in:
\\HKEY_CURRENT_USER\SOFTWARE\ORACLE\WALLETS\SALESAPP\CWALLET.SSO
On Windows operating systems, if there is no value specified for parameter WALLET_LOCATN, then Oracle PKI applications first look for the changed wallet in registry key:
\\HKEY_CURRENT_USER\SOFTWARE\ORACLE\WALLETS\DEFAULT
If no obfuscated wallet is found there, Oracle PKI applications look for it in the file system of the local computer at location:
%USERPROFILE%\ORACLE\WALLETS
Regardless of location, wallets are always stored in the same format. All functionality is the same except for the location of the wallets.
