SMF Type 0 Record

This table shows the record layout for type 0 SMF records
(IPL Header).

List of other SMF record layouts available.
List of sample SMF reports.

Purpose: Record type 0 is written after every SMF initialization. It includes the virtual and central storage sizes and some of the SMF options in effect. See record type 90 (subtype 9) for information about the IPL of SMF.

It's easy to report on SMF 0 data!

We have a low-cost 4GL report writer especially for SMF files. It's called Spectrum SMF Writer.

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

Spectrum SMF Writer also converts the arcane date and time fields and reformats them into an attractive report.

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

This bit is on when one of the following record types is selected: 14, 15, 17, 18, 62, 63, 64, 67 or 68. (See “Selecting SMF records” on page 4-2.) 4 Volume accounting. Record types 10 or 69 selected. (See “Selecting SMF records” on page 4-2.) 5 Reserved. 6 Type 17 records will be written for temporary data sets (REC(ALL)). 7 Reserved.
