Password File - wykład

Password File
A database can use a password file to authenticate administrative users with SYSDBA,
SYSOPER, and SYSBACKUP privileges. A password file is required for remote connections
to the database with any of these privileges. These privileges enable a DBA to start and
shut down the database, back up and recover the database, and perform other
high-level administrative tasks. This password file is outside of the database itself,
thereby enabling the authentication of a DBA when the database is not yet started. (A
DBA must authenticate before starting the database.)
When you invoke DBCA as part of the Oracle Database installation process, DBCA
creates a password file with one entry: the SYS user. Granting SYSDBA, SYSOPER, or
SYSBACKUP to a user adds that user to the password file automatically.
