OS_AUTHENT_PREFIX

Property	Description
Parameter type	String
Syntax	`OS_AUTHENT_PREFIX =` `authentication_prefix`
Default value	`OPS$`
Modifiable	No

OS_AUTHENT_PREFIX specifies a prefix that Oracle uses to authenticate users attempting to connect to the server. Oracle concatenates the value of this parameter to the beginning of the user's operating system account name and password. When a connection request is attempted, Oracle compares the prefixed username with Oracle usernames in the database.

The default value of this parameter is OPS$ for backward compatibility with previous versions. However, you might prefer to set the prefix value to "" (a null string), thereby eliminating the addition of any prefix to operating system account names.

Note:

The text of the OS_AUTHENT_PREFIX parameter is case sensitive on some operating systems.
