DSSM accounting records

General comments on the BS2000 accounting system

The BS2000 accounting system as a whole is controlled by systems support. Systems support determines the time at which the accounting system is to be started, declares the name of the accounting file, and defines the name and number of accounting records and record extensions that are to be recorded in the accounting file.
Systems support also determines the cycle and scope of periodic data entry encompassing certain accounting records and job classes.

The accounting system can be used by systems support to activate and deactivate accounting records, either entirely or in part, during a session, and to influence the extent of the individual accounting records.
Accounting records and record extensions which are not required can be deactivated by means of the MODIFY-ACCOUNTING-PARAMETERS command.

The attributes used in the representation of each data field are as follows:

Field	Consecutive number of the data field within the described part of the record
Displacement	Relative distance of the data field from the start of the described part of the record
Length	Length of the data field in bytes
Format	A = alphanumeric B = binary number B2 =binary representation of CPU time C = printable characters, including special characters F = file name X = non-printable characters Z = unpacked decimal number (*) * = specified for the individual record types or extension elements - = reserved for future extensions; contains either a space or binary zero
(*)	Time is shown in the form hhmmss, the date in the form yymmdd

An accounting record consists of the following four parts:

(A) Record description	record identifier, time stamp,
(B) Identification section	user ID, account number, monitored resources , ...
(C) Basic information	default data
(D) Variable information	record extensions

For more details about the BS2000 accounting system refer to the manual “Introductory Guide to Systems Support” [14].

Subsystem record description

The record description (A) contains a record identifier, which serves the purpose of differentiating the individual accounting records, a time stamp, and details of the length of the identification section and of the basic information.

Address of the record description = left-hand end of record

Structure and contents:

Field no.	Displacement		Length (bytes)	Format	Meaning
	hex.	dec.
1 2 3 4 5	00 04 0C 0E 10	0 4 12 14 16	4 8 2 2 4	A B B B -	Record identifier 1 Time stamp of time of day clock 2 Length of identification section Length of basic information - reserved -

¹The record identifier serves to differentiate between the individual record types.

²The time stamp is entered in the record by the system as the last item of information after creation of the record is completed or after it has been transferred to the accounting system.

Length of the record description: 20 bytes

Subsystem identification

The subsystem identification in the identification section (B) describes the subsystem to which the subsystem account data relates.

Structure and contents:

Field no.	Displacement		Length (bytes)	Format	Meaning
	hex.	dec.
1 2 3 4	00 08 0F 17	0 8 15 23	8 7 8 6	A A Z Z	Name of the subsystem Version of the subsystem Date of the call 1 Time of the call 2

¹Date in the form yyyymmdd

²Time in the form hhmmss

Length of the DSSM identification section: 29 bytes
