I’m lazy when I connect to the database, especially on my laptop. Anything that saves a few keystrokes I’m keen on
So rather than type “sqlplus username/password@database” I like to take advantage of a wallet
In my private sqlnet.ora, or the global one if it makes sense to do so, I add the details of wallet
This tells Oracle, that when I begins a connection to the database, we will look in directory “c:\oracle\wallet” for wallet entries, which I’ll now create
C:\oracle\wallet>mkstore -create -wrl c:\oracle\wallet Oracle Secret Store Tool : Version 220.127.116.11 Copyright (c) 2004, 2014, Oracle and/or its affiliates. All rights reserved.
Enter password: ********
Enter password again: ********
This creates an empty wallet. You’ll need a password for the wallet, which is required whenever maintenance to the wallet is required. Then I add an entry to the wallet for my database, in this case, “MYDB”
C:\oracle\wallet>mkstore -wrl c:\oracle\wallet -createCredential MYDB scott tiger Oracle Secret Store Tool : Version 18.104.22.168 Copyright (c) 2004, 2014, Oracle and/or its affiliates. All rights reserved.
Enter wallet password: ********
Create credential oracle.security.client.connect_string1
I also have a MYDB entry in my tnsnames.ora
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1525))
(SERVICE_NAME = np12)
At this point, we can now connect securely to the database without ever requiring a password to be hard coded on command line, or in an environment variable etc.
The wallet is consulted, which maps MYDB to scott/tiger, and also maps to MYDB in tnsnames.ora, and the two then form the database connection.

Oracle Database 12c Enterprise Edition Release 126.96.36.199.0 – 64bit Production
With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options
SQL> show user
USER is “SCOTT”
You can list the credentials stored in the wallet using
mkstore -wrl c:\oracle\wallet -listCredential
When prompted for a password, enter the password used to create the wallet.
So for me, its about saving on keystrokes, but you can see how using a wallet, also means you can now avoid hard-coding passwords in any of your applications or scripts. There are also additional features for wallets which you can use to prohibit them from being copied across machines etc.
Note: Wallets are like SSH keys. You store them securely and obviously don’t pass them around to people 🙂
