This article is about how to understand the v$pwfile_user view and difference between Oracle11g and 12c. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article.

V$PWFILE_USERS lists the users who have been granted sysdba and sysoper permissions in the password file. If the query is not recorded, then there may be no password file, no password file, of course, sqlplus sys/xx as sysdba users who use sys with sysdba cannot log in. Let's look at the v$pwfile_user views of 11g and 12c.

1. Vroompwfile _ user table (11g)

V$PWFILE_USERS lists all users in the password file, and indicates whether the user has been granted the SYSDBA, SYSOPER, and SYSASM privileges.

SELECT * FROM v$pwfile_users ORDER BY username

II. Vroompwfile _ user table (12c)

V$PWFILE_USERS lists all users in the password file, and indicates whether the user has been granted the SYSDBA, SYSOPER, SYSASM,SYSBACKUP, SYSDG, and SYSKM privileges.

The above is how to understand the v$pwfile_user view and difference between Oracle11g and 12c. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
