ALTER_STATIC_ACL_REFRESH

Alters the refresh mode for a ACLMV for a given table.

Will remove any refresh schedule for this ACLMV. dbms_xds.alter_static_acl_refresh( schema_name IN VARCHAR2 := NULL, table_name IN VARCHAR2, refresh_mode IN VARCHAR2);

TBD

DISABLE_OLAP_POLICY

Disables OLAP policy for a table dbms_xds.disable_olap_policy( schema_nm IN VARCHAR2 := NULL, logical_nm IN VARCHAR2);

exec dbms_xds.disable_olap_policy(logical_nm => 'SCOTT');

      

      PL/SQL procedure successfully completed.

DISABLE_XDS

Disable an XDS policy for a table dbms_xds.disable_xds( object_schema IN VARCHAR2 := NULL, object_name IN VARCHAR2, policy_name IN VARCHAR2 := NULL);

exec dbms_xds.disable_xds('SCOTT', 'EMP');

      *

      ERROR at line 1:

      ORA-46004: XS Data Security policy is not applied on SCOTT.EMP

DROP_OLAP_POLICY

Drops an OLAP policy from a table dbms_xds.drop_olap_policy( schema_nm IN VARCHAR2 := NULL, logical_nm IN VARCHAR2);

exec dbms_xds.drop_olap_policy(logical_nm => 'SCOTT');

      

      PL/SQL procedure successfully completed.

DROP_XDS

Drop an XDS policy from a table dbms_xds.drop_xds( object_schema IN VARCHAR2 := NULL, object_name IN VARCHAR2, policy_name IN VARCHAR2 := NULL);

exec dbms_xds.drop_xds('SCOTT', 'EMP');

      *

      ERROR at line 1:

      ORA-46007: no XS Data Security policy associated with SCOTT.EMP

ENABLE_OLAP_POLICY

Enable_olap_policy - enable OLAP policy for a table dbms_xds.enable_olap_policy( schema_nm IN VARCHAR2 := NULL, logical_nm IN VARCHAR2, policy_nm IN VARCHAR2, overwrite IN BOOLEAN := NULL);

TBD

ENABLE_XDS

Enable an XDS policy for a table dbms_xds.enable_xds( object_schema IN VARCHAR2 := NULL, object_name IN VARCHAR2, enable_option IN BINARY_INTEGER := NULL, policy_name IN VARCHAR2, usermv_name IN VARCHAR2 := NULL);

TBD

PURGE_ACL_REFRESH_HISTORY

Purges ACL refresh history in XDS_ACL_REFRESH_STATUS for the table's ACLMV dbms_xds.purge_acl_refresh_history( object_schema IN VARCHAR2 := NULL, object_name IN VARCHAR2, purge_date IN DATE := NULL);

sys@pdbdev as sysdba

      

      exec dbms_xds.purge_acl_refresh_history('SCOTT', 'EMPCOPY', SYSDATE+1/60);

      SCOTT,EMPCOPY

      

      PL/SQL procedure successfully completed.

SCHEDULE_STATIC_ACL_REFRESH

Schedules automatic refresh of an ACLMV for a given table.

Will change the refresh mode of the corresponding ACLMV to "ON DEMAND" dbms_xds.schedule_static_acl_refresh( schema_name IN VARCHAR2 := NULL, table_name IN VARCHAR2, start_date IN TIMESTAMP WITH TIME ZONE := NULL, repeat_interval IN VARCHAR2 := NULL, comments IN VARCHAR2 := NULL);

exec dbms_xds.schedule_static_acl_refresh('SCOTT', 'EMP', SYSDATE+1/60);

      

      PL/SQL procedure successfully completed.

SET_TRACE_LEVEL

Sets the trace level. The tracing info of the scheduled mv refresh is logged in aclmv$_reflog table, and is useful for debugging. dbms_xds.set_trace_level( schema_name IN VARCHAR2, table_name IN VARCHAR2, level IN NUMBER);

exec dbms_xds.set_trace_level('SCOTT', 'EMP', 12);

      *

      ERROR at line 1:

      ORA-46025: no static rule specified in applied policy

XDS$REFRESH_STATIC_ACL

Scheduler callback procedure to refresh the acl-mv on a table dbms_xds.xds$refresh_static_acl( schema_name IN VARCHAR2, table_name IN VARCHAR2, mview_name IN VARCHAR2, job_name IN VARCHAR2);
