Save Oracle grants tips

Oracle Database Tips by Donald BurlesonFebruary 4, 2015

How do I extract all of my user grants?  I plan to delete and re-add a schema and I want to save a copy of all of my grants.


Answer:  To "punch off" and save all security grants to users, I recommend using th dbms_metadata  package.  As you know, there are three types of grants:


   1) system grants
   2) object grants
   3) role grants


Also, beware that data access many also be controlled by virtual private database security and "grant execute" security" commands, so saving all f the grants may not capture all of the possible security for Oracle.


The following script will invoke dbms_metadata to save all grants within a schema.  Please see the Oracle script collection for a complete set of Oracle security scripts.


To use this script, just enter the schema owner (username) into the following code to display the grant statements for that schema owner:


connect username/password;

select dbms_metadata.get_granted_ddl('system_grant','') from dual;

select dbms_metadata.get_granted_ddl('role_grant','') from dual;
select dbms_metadata.get_granted_ddl('object_grant','') from dual;
