Oracle DBMS_CACHEUTIL Version 12.2.0.1

General Information

Library Note

Morgan's Library Page Header

The Library is currently in the process of being upgraded from Oracle Database Version 12.1.0.2 to 12.2.0.1. Demos are being upgraded to reflect the new Container paradigm as well as EBR (Edition Based Redefinition) and may contain references to CDBs, PDBs, and other objects you may not be familiar with such as CDB_OBJECTS_AE: Welcome to 12c.

Also important ... there are rumors on the web about SPARC and Solaris being discontinued. Welcome to the age of fake news. There is absolutely not a byte of truth to these irresponsible rumors.

Purpose This undocumented package contains miscellaneous cache layer PL/SQL functions

DISSOLVE_AFFINITY

Try to dissolve object affinity in RAC environment dbms_cacheutil.dissolve_affinity( schema IN VARCHAR2, obj IN VARCHAR2, partition IN VARCHAR2 := NULL, dissolve_index IN BOOLEAN := TRUE, active_drm IN BOOLEAN := FALSE);

exec dbms_cacheutil.dissolve_affinity(USER, 'SERV_INST');

DISSOLVE_READMOSTLY

Try to dissolve object readmostly in a RAC environment dbms_cacheutil.dissolve_readmostly( schema IN VARCHAR2, obj IN VARCHAR2, partition IN VARCHAR2 := NULL, dissolve_index IN BOOLEAN := TRUE);

exec dbms_cacheutil.dissolve_readmostly(USER, 'SERV_INST');

GRAB_AFFINITY

Try to grab object affinity in a RAC environment dbms_cacheutil.grab_affinity( schema IN VARCHAR2, obj IN VARCHAR2, partition IN VARCHAR2 := NULL, grab_index IN BOOLEAN := TRUE, active_drm IN BOOLEAN := FALSE);

exec dbms_cacheutil.grab_affinity(USER, 'SERV_INST');

GRAB_READMOSTLY

Try to grab object readmostly in RAC environment dbms_cacheutil.grab_readmostly( schema IN VARCHAR2, obj IN VARCHAR2, partition IN VARCHAR2 := NULL, grab_index IN BOOLEAN := TRUE);

exec dbms_cacheutil.grab_readmostly(USER, 'SERV_INST');

LIST_READMOSTLY

List objects that have the readmostly property set dbms_cacheutil.list_readmostly;

exec dbms_cacheutil.list_readmostly;

OBJECT_DOWNCONVERT

Tries to downconvert object locks to shared mode in RAC dbms_cacheutil.object_downconvert( schema IN VARCHAR2, obj IN VARCHAR2, partition IN VARCHAR2 := NULL, downconvert_index IN BOOLEAN := TRUE);

exec dbms_cacheutil.object_downconvert(USER, 'SERV_INST');
