Check management class definitions

To determine the storage class and management class names associated with the object, use the following SQL statement:

SELECT * FROM OAMADMIN.CBR_STO_CLASS_TBL S,
         OAMADMIN.CBR_MGT_CLASS_TBL M,
         HLQ.OSM_OBJ_DIR D
WHERE   ODNAME = 'object_name'
AND     D.ODSCNUM = S.ODSCNUM
AND     D.ODMCNUM = M.ODMCNUM;

If no rows are produced from the select statement, the object is not processed.

List the ISMF definition of the management class name returned from the select statement. This is the management class currently assigned to the object. Specify ACTIVE as the SCDS name.

Calculate the date of the next class transition as follows:

If TIME SINCE CREATION has been used, add the values for time since creation to the creation date of the object (ODCREATS in the object's directory table entry).
If TIME SINCE LAST USE has been specified, add the values for time since last use to the last referenced date of the object (ODLREFDT in the object’s directory table entry).
If PERIODIC has been specified, see the period definitions in the z/OS DFSMSdfp Storage Administration.

In all cases, if the date calculated is in the future, no class transition occurs.
