DCOLLECT Type C Record

This table shows the record layout for type C DCOLLECT records
(DASD Capacity Planning Information).

Purpose: The DFSMS Data Collection Facility (DCOLLECT) is a function of access method services. DCOLLECT collects stored data set, volume and policy values into a sequential file you can use as input to other programs or applications.

The DCOLLECT output file consists of a number of different record types.

Type C records contain DASD capacity planning information. If DASD capacity planning records are requested, one record is created for each level 0 and level 1 volume for each day there was activity. For example, if five volumes had DFSMShsm activity for seven days, there would be 35 DASD capacity planning records. The number of days that volume statistics are kept to create these records can be controlled by the MIGRATIONCLEANUPDAYS parameter of the DFSMShsm SETSYS command.

 


It's easy to report on DCOLLECT type C records!
