Using an Oracle Wallet with dbfs_client

You can use an Oracle Wallet to mount the file system using dbfs_client without having to enter a password. Using a wallet allows you to do the mount in the background in a more secure manner than reading the password from a text file. The wallet also makes it easier to use dbfs_client for file system tasks.

Create an Oracle Wallet

Create a directory for the wallet.

[oracle@ora1 ~]$ mkdir -p $HOME/oracle/wallet

Create an auto-login wallet. You will be prompted to enter a password for the wallet.

[oracle@ora1 ~]$ mkstore -wrl $HOME/oracle/wallet -create
Oracle Secret Store Tool : Version 11.2.0.1.0 - Production

Enter password:              

Enter password again:              

[oracle@ora1 ~]$

Add the credentials to the wallet

[oracle@ora1 oracle]$ mkstore -wrl $HOME/oracle/wallet -createCredential orcl oradbfs password
Oracle Secret Store Tool : Version 11.2.0.1.0 - Production
Copyright (c) 2004, 2009, Oracle and/or its affiliates. All rights reserved.

Enter wallet password:              

Create credential oracle.security.client.connect_string1
[oracle@ora1 oracle]$

Add the wallet location and the SQLNET.WALLET_OVERRIDE parameter to the clients sqlnet.ora file.

WALLET_LOCATION = (SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=$HOME/oracle/wallet)))
SQLNET.WALLET_OVERRIDE=TRUE

Now that the wallet is created with the credentials added for the oradbfs user let try a simple test using SQL*Plus. To use the wallet use the /@

[oracle@ora1 oracle]$ sqlplus /@orcl

Using /@orcl we were logged directly into the database without entering a username or password.

Using the wallet we can now mount the file system in the background.

[oracle@ora1 oracle]$ nohup dbfs_client -o wallet /@orcl /u01/app/oracle/dbfs
nohup: appending output to `nohup.out'
[oracle@ora1 oracle]$ df -h
