Creating a Password File with ORAPWD

ORAPWD FILE=filename [ENTRIES=numusers] [FORCE={Y|N}] [IGNORECASE={Y|N}]
Argument Description
FILE Name to assign to the password file. You must supply a complete path. If you supply only a file name, the file is written to the current directory.
ENTRIES (Optional) Maximum number of entries (user accounts) to permit in the file.
FORCE (Optional) If y, permits overwriting an existing password file.
IGNORECASE (Optional) If y, passwords are treated as case-insensitive.

ORAPWD Command Line Argument Descriptions

Platform Required Name Required Location)
Windows PWDORACLE_SID.ora ORACLE_HOME\database

Create the Oracle Password

  1. Log on to the database as an administrative user.

  2. Shutdown the database.

  3. On Linux/UNIX: cd $ORACLE_HOME/dbs, Windows: cd %ORACLE_HOME%\database

  4. Issue the orapwd command:

    $ orapwd
    Usage: orapwd file=[fname] password=[sys password] entries=[users] force=[y/n] ignorecase=[y/n] nosysdba=[y/n]
    $ orapwd file=orapwTEST01 password=geeklab ignorecase=n
    • file – name of password file (required)
    • password – password for SYS will be prompted if not specified at command line
    • entries – maximum number of distinct DBA (optional)
    • force – whether to overwrite existing file (optional)
    • ignorecase – passwords are case-insensitive (optional)
    • nosysdba – whether to shut out the SYSDBA logon (optional Database Vault only, deprecated in 11.2)
  5. Add the below parameter in the pfile of the TEST01 database instance:

  6. After all the above has been done, run this statement:

    SQL> select * from v$pwfile_users;

Should this statement return any records, attempt a passwordfile authenticated sysdba connection. Should the connection work, everything is working fine. If the statement returns no records, the database instance must be restarted.

Adding Users to a Password File

Creating a Password File and Adding New Users to It

  1. Follow the instructions for creating a password file as explained in “Creating a Password File with ORAPWD”.

  2. Set the REMOTE_LOGIN_PASSWORDFILE initialization parameter to EXCLUSIVE. (This is the default.)

    Note: REMOTE_LOGIN_PASSWORDFILE is a static initialization parameter and therefore cannot be changed without restarting the database.

  3. Connect with SYSDBA privileges as shown in the following example, and enter the SYS password when prompted:

  4. Start up the instance and create the database if necessary, or mount and open an existing database.

  5. Create users as necessary. Grant SYSDBA or SYSOPER privileges to yourself and other users as appropriate. See “Granting and Revoking SYSDBA and SYSOPER Privileges”, later in this section.

Maintaining a Password File

Expanding the Number of Password File Users

  1. Identify the users who have SYSDBA or SYSOPER privileges by querying the V$PWFILE_USERS view.
  2. Delete the existing password file.
  3. Follow the instructions for creating a new password file using the ORAPWD utility in “Creating a Password File with ORAPWD”. Ensure that the ENTRIES parameter is set to a number larger than you think you will ever need.
  4. Follow the instructions in “Adding Users to a Password File”.

Removing a Password File

If you determine that you no longer require a password file to authenticate users, you can delete the password file and then optionally reset the REMOTE_LOGIN_PASSWORDFILE initialization parameter to NONE. After you remove this file, only those users who can be authenticated by the operating system can perform SYSDBA or SYSOPER database administration operations.
