Oracle achieved using the wallet password-free login

Oracle provides a concept called wallet, is to exist inside the wallet password, then login time automatically extract the password from the wallet inside, without the need to enter a password every time the command line.

The benefit of this is a scripting language which can block access authentication information Oracle database.

step

1. Creating a wallet

$ mkstore -wrl /path_to/mywallet -create

This step requires a password wallet inside, and modify the password in the wallet when it will be used, including the back of the add / delete / modify any database connection information, but do not need to read the password to access an Oracle connection.

The result is two files in / path_to mywallet below / directory: cwallet.sso ewallet.p12

2. Add a database connection information to the wallet

$ mkstore -wrl /path_to/mywallet -createCredential myorcl scott tiger

Wherein parameters:
myorcl: a connection identification Oracle database, an item is defined in the tnsnames.ora.
scott / tiger: of course, is the user name and password.

This step requires a password set when creating a wallet in front.

3. Modify the $ ORACLE_HOME / network / admin / sqlnet.ora

Add the following two lines:

WALLET_LOCATION=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=/path_to/mywallet)))
SQLNET.WALLET_OVERRIDE = TRUE

4. Modify the $ ORACLE_HOME / network / admin / tnsnames.ora

Define a database connection attribute identifies myorcl of:

myorcl = 
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.xxx.xxx.xxx)(PORT = 1521))
    (CONNECT_DATA=
      (SERVER = DEDICATED)
      (SERVICE_NAME=orcl)
    )
  )

5. Test sqlplus

$ sqlplus /@peppino
