 duty security model tips

Oracle Database Tips by Donald BurlesonMarch 16, 2015

Question:  How do I use the 12c DBA duty security model?

Answer:  Prior to Oracle 12c, the SYSDBA (and SYSOPER) had many non-specific DBA privileges and there was no segregation of duties among Oracle DBA job duties.  There are now six different system-level roles fr the DBA, segregated along job duty lines:

  •  SYSDBA ROLE: User name SYS/PUBLIC - This is the same full DBA system operations and privileges as in release 11g and earlier.

  • SYSOPER Role:  user name SYS/PUBLIC - This is the same same system operations and privileges for release 11g and earlier.

12c Data Security Model users and roles:

  • SYSASM Role:  - user name SYS - The SYSSM role gives privileges for administering an Automatic Storage Management (ASM) instance.

  • SYSBACKUP Role: User name SYSBACKUP - The SYSBACKUP role gives the ability to perform RMAN backup and recovery commands both from SQL*Plus (SQL Developer) and RMAN command line.   In a nutshell, the sysbackup privilege allows the DBA to perform RMAN backup command without additional DBA privileges. 

  • SYSDG Role:  User name SYSDG - The SYSDG role gives the ability to perform Data Guard operations with Data Guard Broker or the DGMGRL command line.

  • SYSKM Role:  Username SYSKM - The SYSKM role gives the ability to manage the encryption keys for Transparent Data Encryption.
