The STAT-FILE File

The STAT-FILE file contains the following data items from which to produce a File Statistics Report:

0

ID (REEL :FILE)

Number of the reel in a multireel filesave, followed by the number of the file. The file number is used with the N option when restoring files.

1

NAME

Account name, dictionary file name, and data file name, separated by * (i.e., SYSPROG*BP*BP). When dictionaries and data files have the same name, the data file is listed as filename*filename. File names that contain * will cause the File Statistics Report to misname files.

2

FILE LEVEL #

A number from 0-3:

0

System level.

1

Master dictionary level.

2

File dictionary level.

3

Data file level.

3

BASE

Base frame ID of the file.

4

MODULO

Number of groups.

5

SEPARATION

Number of frames initially allocated to a group. Always a 1.

6

# ITEMS

How many records in the file just saved.

7

# BYTES

How much data saved.

8

LARGEST ITEM SIZE

9

SMALLEST ITEM SIZE

10

# ITEMS IN FULLEST GROUP

11

# ITEMS IN EMPTIEST GROUP

12

# FRAMES USED

Total number of frames used by the file, including full and partially full frames, allocated frames, secondary file space and object code frames.

13-20 REPRESENT A LOGICAL SET

13

# GROUPS 25% FULL

14

# GROUPS 50% FULL

15

# GROUPS 75% FULL

16

# GROUPS 100% FULL

17

# GROUPS 125% FULL

18

# GROUPS 150% FULL

19

# GROUPS 200% FULL

20

# GROUPS >200% FULL

Total should be equal to the modulo. Items 17-20 (particularly 20) should indicate as few groups as possible.

21

# GFEs

Critical information. On a system level, should be checked daily. If other than 0, must be addressed immediately.

22

# OBJECT CODE FRAMES

Total number of frames of object code used by programs and select-lists.

23

NOT USED IN mvBase

24

NOT USED IN mvBase

25

# INDIRECT ITEMS

26

TOTAL SIZE OF ALL INDIRECT ITEMS

27

RAW BYTES (DIRECT)

Total of attribute 26 and attribute 27 equal the number in attribute 7.

28

REEL #

Printing out an entire STAT-FILE file could mean several thousand pages and would be essentially inefficient. A more practical use of this file is to focus on getting information about specific system management problems, producing smaller and more useful reports.
