DCOLLECT Type DC Record

This table shows the record layout for type DC DCOLLECT records
(Data Class Construct 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 DC records contain data class construct information. These records are collected when SMSDATA is selected, and data class constructs are defined to the control data set selected. The record type for this record is 'DC'.

 

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

DCOLLECT Spectrum WRITER
We have a low-cost 4GL report writer especially for DCOLLECT files. It's called Spectrum DCOLLECT Reporter.

Spectrum DCOLLECT Reporter handles the difficult DCOLLECT record parsing for you automatically. You just specify which fields you want to see.

Spectrum DCOLLECT Reporter also converts the arcane date and time fields and reformats them into an attractive report. It defines the individual bit flags for easy testing or printing.

Plus, Spectrum DCOLLECT Reporter can export DCOLLECT data as comma delimited files to use on your PC.
