ORA-01017 During Logon with Password Having Special Characters (Doc ID 2901628.1)

• Choose passwords carefully.

         Minimum Requirements for Passwords describes the minimum requirements for passwords. Follow these additional guidelines when you create or change passwords:

• Make the password have a length of between 12 and 30 bytes, and include both alphabetic characters and digits in the password.
• Have the password contain at least one digit, one upper-case character, and one lower-case character.
• Use mixed case characters and special characters in the password. (See Ensuring Against Password Security Threats by Using the 12C Password Version for more information.)
• You can include multibyte characters in the password but not in the password of any common user or role.
• Use the database character set for the password's characters, which can include the underscore (_), dollar ($), and number sign (#) characters.
• You must enclose the following passwords in double-quotation marks:
  • Passwords containing multibyte characters
  • Passwords starting with numbers or special characters and containing alphabetic characters. For example:
    

    "123abc"

    "#abc"

    "123dc$"

  • Passwords containing any character other than alphabetic characters, numbers, and special characters. For example:

                     "abc>"

                     "abc@",

                     " "

• You do not need to specify the following passwords in double-quotation marks.
  • Passwords starting with an alphabetic character (a–z, A–Z) and containing numbers (0–9) or special characters ($, #, _). For example:
    

     abc123

     ab23a

     ab$#_

  • Passwords containing only numbers
  • Passwords containing only alphabetic characters (a–z, A–Z)

• Do not include double-quotation marks within the password.
• Do not use an actual word for the entire password.
