The best Oracle News for FY2026

Oracle Database 26ai will be available on generic Linux platforms in January and soon on AIX and Windows

Purpose Contains functions that retrieve factor identities. After Oracle Database Vault installation, the install process locks the DVF account to enhance security.

When creating a new factor, Database Vault creates a new retrieval function for the factor owned by the DVF schema.

CREATE_FACTOR_FUNCTION

Create retrieval function dbms_macsec_function.create_factor_function(p_factor IN VARCHAR2);

exec dvf.dbms_macsec_function.create_factor_function('ZZYZX');

      

      PL/SQL procedure successfully completed.

The demo, at right, is from $ORACLE_HOME/rdbms/admin/catmact.sql reformatted for readability since no one has taught developers at Oracle how to format their code. dbms_macsec_function.create_factor_function(p_factor IN VARCHAR2);

DROP_FACTOR_FUNCTION

Drop a retrieval function.

The demo, at right, is from $ORACLE_HOME/rdbms/admin/dve12.sql dbms_macsec_function.drop_factor_function(p_factor IN VARCHAR2);

execute dvf.dbms_macsec_function.drop_factor_function('DV$_Module');

      execute dvf.dbms_macsec_function.drop_factor_function('DV$_Client_Identifier');

      execute dvf.dbms_macsec_function.drop_factor_function('DV$_Dblink_Info');

TO_ORACLE_IDENTIFIER

Converts the input string into a valid Oracle object name

Note in the demo, at right, a space in the string is converted to an underscore dbms_macsec_function.to_oracle_identifier(str IN VARCHAR2) RETURN VARCHAR2;

SELECT dvf.dbms_macsec_function.to_oracle_identifier('ZZ ZZ');

      

      DVF.DBMS_MACSEC_FUNCTION.TO_ORACLE_IDENTIFIER('ZZZZ')
