Oracle Wallet Manager - Oracle 10g/11g Data and Database Management Utilities - page 243

Once the Oracle Wallet has been configured and the database credentials have been
stored the user can access the Oracle database from any tool requiring the user to
provide access to the database. The access granted to the user will be just like as
though the user has provided the password at connect time.
As the database credentials are stored in an area different from the area where the
PKI certificates are stored, you cannot use the graphical interface to manage the
database user credentials, you must use the mkstore command line utility instead.
There are different options available for the mkstore utility:
• Listing External Password Store Contents.
mkstore -wrl <wallet_location> -listCredential
• Adding Credentials to an External Password Store.
mkstore -wrl <wallet_location> -createCredential <db_alias> <user-
name> <password>
• Modifying Credentials in an External Password Store.
mkstore -wrl <wallet_location> -modifyCredential <dbase_alias>
<username> <password>
• Deleting Credentials from an External Password Store.
mkstore -wrl <wallet_location> -deleteCredential <db_alias>
