Oracle Wallet Usage – External Passwords Store
In the previous blog post, we discussed Introduction to Oracle Wallet Click here to read more. In this blog post, we will see How to configure Oracle Wallet to store User passwords.
Oracle Wallet provides a simple and easy method to manage database credentials across multiple domains. It allows you to update database credentials by updating the Wallet instead of having to change individual datasource definitions. This is accomplished by using a database connection string in the datasource definition that is resolved by an entry in the wallet.
This feature can be taken a step further by also using the Oracle TNS (Transparent Network Substrate) administrative file to hide the details of the database connection string (host name, port number, and service name) from the datasource definition and instead use an alias. If the connection information changes, it is simply a matter of changing the tnsnames.ora file instead of potentially many datasource definitions.
Follow the below steps to configure External Password Store:
1. Demo Setup
2. Create a wallet
3. Setup sqlnet.ora to use wallet file
4. Add user to wallet and verify
5. Modify wallet user password
6. Delete wallet user
Step 1. Demo Setup: For the purpose of the demo, We have created user app_user with password test123 and also added tnsentry with alias app_user. Basically, Wallet db_connection_string and tnsentry alias should have the same name if you are doing connection using tnsnames.ora.

Step 2. Create a wallet: Create a wallet on the client by using the following syntax at the command line. If you have already an existing wallet you can skip Step 2 and continue with Step 3. Use option -create and -listCredential with mksore command to create and to list credential in the wallet.

List credential (index: connect_string username)
[oracle@test-machine01 wallet_1]$
[oracle@test-machine01 wallet_1]$
Step 3. Setup sqlnet.ora to use wallet file: Update parameter WALLET_LOCATION in sqlnet.ora file in the client-side to specify wallet location. The WALLET_OVERRIDE in the sqlnet.ora file specifies to override any existing OS authentication password configuration.
[oracle@test-machine01 admin]$
[oracle@test-machine01 admin]$ vi sqlnet.ora
WALLET_LOCATION =
(SOURCE =
(METHOD = FILE)
(METHOD_DATA =
(DIRECTORY = /u01/app/oracle/admin/wallet_1)
)
)
SQLNET.WALLET_OVERRIDE = TRUE
:wq!
[oracle@test-machine01 admin]$
Step 4. Add user to wallet and verify: Syntax to add users in wallet, mkstore -wrl <wallet location> -createCredentail <db_connect_string> <user> <password>. In below example we are adding 2 entry in wallet.
1. db_connect_string = APP_USER – This APP_USER connection string should be the same as the tnsentry alias name if you want to use tnsnames.ora file.
2. db_connect_string = long form of the connection URL – With this format you can connect directly to the database without the need of tnsnames.ora file as you are providing full details like Hostname, Port , Service_Name in the connection string.
Once wallet entries are ready you can use tools like sqlplus to connect to the database. Syntax : sqlplus /@< db_connect_string > without mentioning Username and Password.

Step 5. Modify wallet user password: Here we are modifying the APP_USER password from test123 and app123. As soon as the password is changed. We need to update wallet user password as well otherwise end users will not be able able to connect to the database and will receive the error “ORA-01017: invalid username/password; logon denied“. Use mkstore -modifyCredential to modify wallet entries.
