You must code the user exit routine ACCTRTE to populate account
code values after they have been defined. This exit is
invoked to build the ACCTNOx data elements, where x is the
account code level. For example, if the ACCOUNT member
defines three account code levels, the ACCTRTE exit routine
is coded to populate data elements ACCTNO1, ACCTNO2, and
ACCTNO3. The values assigned to the ACCTNOx data elements in
ACCTRTE are global and, by default, these values are used in
every observation written for every address space type for a
particular job.
This routine executes only once for each RDRTS and JOB
combination encountered, when CA MICS first merges the various
SMF record types for each unique address space. The ACCTNOx
values set in ACCTRTE will be used in the BATJOB observation
for the job, and in each step or interval observation written
to the step-level files. The ACCTNOx values can be
overridden in the USRSPGM user exit for the step-level files,
and in USRSSPL for the BATSPL files.
Data element, ACCTMASK, which is kept in all batch
information area files, shows which SMF record types were
present when the ACCTRTE routine was executed to assign the
ACCTNOx values. ACCTMASK can be used as a debugging tool if
problems occur with your ACCTRTE routine code.
A similar data element found in the BATJOB file, JOBMASK,
shows the SMF records that were present when the BATJOB
observation was built. JOBMASK sometimes has more SMF record
types present than ACCTMASK, because JOBMASK is updated daily
for jobs suspended in the BAT_JS file when new SMF data is
processed.
PREPARATION
Use SAS to code the ACCTRTE routine, and ensure there are no
syntax errors. A sample ACCTRTE member is provided in
sharedprefix.MICS.PARMS(ACCTRTE) as a template. Refer to
Section 2.3.1.5, Notes on Coding CA MICS Parameters, in the
PIOM for assistance. Figure 7-2 provides a worksheet to code
your routine.
DATA ELEMENTS FOR ACCOUNT CODE ROUTINE
CA MICS merges the following list of SMF record types for
each address space type input from the SMF raw data file.
When ACCTRTE is invoked, it has access to all data elements
in the first observation encountered for each unique SMF
record type associated with the address space. At least one
of these SMF record types is present when ACCTRTE is invoked.
USEFUL FOR THE ACCTRTE EXIT
o Job Initiation (SMF record type 30 subtype 1)
o Job End (SMF record type 30 subtype 5)
o Job Purge (SMF record type 26)
The job purge record has limited
usefulness in the ACCTRTE exit.
ACCTRTE is entered only once, when CA
MICS first encounters records for an
address space. The purge record is
often not available because it is the
last record written for an address
space. The scenarios that make the
purge record useful for account code
setting generally involve SYSOUT-only
jobs, where no job execution SMF
record types are encountered. To
guarantee that CA MICS will wait for
the purge record in these SYSOUT-only
jobs, you should code an SPLLIMIT
statement as described in Section
7.3.1.3.
o BATSFH Job Account Derivation Hold File observation
USEFUL FOR STEP-LEVEL ACCOUNTING
o Step/Interval (SMF record type 30 subtypes 2, 3, or
4)
USEFUL FOR SPOOL (OUTPUT RECORD) LEVEL ACCOUNTING
o Output Writer (SMF record type 6)
NOT USEFUL FOR ACCOUNTING
o MDS Mount (SMF record type 25 - JES3 only)
The Job Account Derivation Hold (BATSFH) file is a special
file designed to supply accounting information for certain
types of SYSOUT. It is fully described in Section 5.2.10.
SYSOUT accountability is discussed in Section 6.3.4.
Setting global ACCTNOx values for an address space implicitly
excludes dependence on data elements found in step, interval,
and output writer records. A given address space may have
numerous steps and SYSOUT data sets. The ACCTRTE is invoked
only once, when the first step or interval record, and the
first output writer record, if present, are in the SAS input
data buffer. It does not make sense to set global, job-level
account code values from SMF records that do not represent
all aspects of the job. The ACCTNOx account code values set
in the ACCTRTE exit are, by default, used for every CA MICS
database observation written for the address space. Their
values represent accountability for all system resources
consumed by executing and printing the job. They should,
therefore, be derived from sources that give information
about the entire job, not just one step or output data set.
Most account code schemes rely on information that is
auditable during job read-in time or address space
initialization time. JES2, JES3, MVS, and RACF all provide
exit points to verify and control certain important value
specifications, such as the job card account fields or RACF
user ID. The most common fields used to set ACCTNOx values
are shown below. Additionally, any data element in the Batch
User Job Activity (BATJOB) file is available to the account
code routine.
o AVAILABLE FROM JOB INITIATION (SMF 30_1), JOB END (SMF
30_5), AND BATSFH FILE:
ACTFLD1-5 - The first five SMF accounting fields from
the JOB card (carried as 20-character
fields). A field that was not specified
will be blank.
JOB - Job Name
JOBCLASS - Job Input Class
JOBPRTY - Job Input Priority
PERFGRP - Performance Group Number
JOBPRGNM - Job Programmer Name
SYSID - SYSID where job executed
PGMTYPE - Variable to define address space type:
batch - PGMTYPE=1
TSO - PGMTYPE=2
started task - PGMTYPE=3
APPC/MVS TP - PGMTYPE=4
USS - PGMTYPE=5
SA - PGMTYPE=6
RACFUSID - RACF User ID
RACFGRID - RACF Group ID
RACFTERM - RACF Terminal ID
o AVAILABLE FROM JOB PURGE (SMF 26)
JOBNETAC - NJE Network Account Number
The above fields represent the information that most sites
use to set account codes and assign responsibility for system
resource consumption. Because any combination of SMF record
types may be present for a given address space, CA MICS
provides a number of internal fields that you may reference
within your account routine. These temporary data elements
are populated prior to invoking the ACCTRTE exit and allow
you to determine which SMF record types are present.
I_AUDIT - Job Initiation Record Indicator
I_AUDIT='I' specifies record present
I_AUDIT='.' specifies no record present
S_AUDIT - Step Termination Record Indicator
S_AUDIT='S' specifies record present
S_AUDIT='.' specifies no record present
J_AUDIT - Job Termination Record Indicator
J_AUDIT='J' specifies record present
J_AUDIT='.' specifies no record present
W_AUDIT - Writer Record Indicator
W_AUDIT='W' specifies record present
W_AUDIT='.' specifies no record present
P_AUDIT - Job Purge Record Indicator
P_AUDIT='P' specifies record present
P_AUDIT='.' specifies no record present
JOBMASK/ - Five-byte fields defining the records present
ACCTMASK for this particular job. These fields are the
concatenation of the above five fields and are
provided to simplify status testing. For
example, a job that has at least one record
present for each record type would have a
JOBMASK equal to ISJWP. A job consisting of
NJE routed output writer records would have a
JOBMASK equal to ...WP.
At the point where ACCTRTE is entered, both
JOBMASK and ACCTMASK have identical values.
Later, when the BATJOB observation is written
to the CA MICS database, JOBMASK and ACCTMASK
may not be equal. This inequality occurs because JOBMASK
reflects all SMF record types that CA MICS encounters
for the job prior to output to the
BATJOB file. These SMF records may be
encountered over several CA MICS daily update
runs. ACCTMASK, on the other hand, never
changes. Its value is set once, when CA MICS
encounters the job for the first time and
enters ACCTRTE.
H_AUDIT - Job Account Derivation Hold File Indicator -
H_AUDIT='H' specifies observation present -
H_AUDIT='.' specifies no observation present
ACCTINFO - Indicates the presence of job-level accounting
information. If one of the following
conditions are true then CA MICS sets
ACCINFO=1 prior to the invocation of the
ACCTRTE exit. Otherwise CA MICS sets
ACCTINFO=0.
o Job initiation record (I_AUDIT='I')
o Job end record (J_AUDIT='J'),
o An observation from the Job Account
Derivation Hold (BATSFH) file
(H_AUDIT='H')
o A SMF type 26 purge record (P_AUDIT='P')
and Job Card Account Fields Flag
(SMF26ACT) is set to indicate job card
account fields are present
o A SMF type 6 output writer record
(W_AUDIT='W') and Job Card Account Fields
Flag (SMF6ACT) is set to indicate job card
account fields are present.
FLUSHJOB - Set to 0 upon entry to the exit
If you want to discard the job being
processed, set the FLUSHJOB indicator to 1.
This setting prevents CA MICS from creating a BATJOB
observation for the job. Step and interval
records for the job still write to
the step-level CA MICS database files and
output writer records still write to
the BATSPL file. You should use the FLUSHJOB
facility with great caution.
Note: The code written in ACCTRTE must only assign values
to the ACCTNOx data elements. In other words, the
only SAS assignment statements in your ACCTRTE should
look like either of these:
ACCTNO1=ACTFLD1 ;
ACCTNO2=RACFUSID ;
Never, under any circumstances, assign values to any
data elements besides ACCTNOx.
CODING CONSIDERATIONS
In coding the ACCTRTE, consider the following information:
o Common data element Time Zone (ZONE) should not be
referenced by your account routine. At the point that
ACCTRTE is invoked, ZONE has not been determined. ZONE
is calculated for each individual interval, step, and
output writer record based on ENDTS and is available in
the user exits invoked just prior to the output of CA
MICS database observations.
o Always validate the information in the fields you use
to set ACCTNOx values. When invalid information is
encountered, set the ACCTNOx values to values
representing your data center's overhead account.
Note: Setting ACCTNOx values to invalid values
increases the number of records and, therefore,
increases the DASD space requirements of the CA MICS
summary database files. For example, if the
first account field on a job card (ACTFLD1)
represents the division and you know that there
are only six divisions in the company, verify
that ACTFLD1 contains one of the six division
values before setting ACCTNO1=ACTFLD1. Failure
to do so can result in unnecessarily large DASD
requirements because CA MICS creates a
summary observation for each unique value
encountered in the account codes.
o You must verify that the information required to set
account codes is available before assignment. For
example, the job card accounting fields (ACTFLD1-5) are
only available if one or more of the following are
present when your account routine is entered:
Job Initiation Record (SMF type 30 subtype 1)
Job End Record (SMF type 30 subtype 5)
BATSFH File Observation
SMF Type 26 Purge Record
When the internal data element ACCTINFO=1, at least one
of these four sources of job-level account information
is available.
Note: The BATSFH file is a special, customized,
internal CA MICS file that can provide accountability
for certain types of SYSOUT that would otherwise be
charged to overhead accounts. See Section 6.3.4 for
information on SYSOUT accountability. Section 5.2.10
explains the BATSFH file and its customization.
o If you have decided to use either the LATEJOB or NJEJOB
option statements (see sections 7.3.1.5 and 7.3.1.6) to
force the creation of BATJOB observations for SYSOUT,
you should write code in ACCTRTE to supply ACCTNOx
values for these SMF record sets. These record sets
will never have a job initiation or job end record to
provide the ACTFLDx and other job-related values
traditionally used to set ACCTNOx values. If you have
activated the BATSFH file, some of these record sets
will be associated with a BATSFH file observation and
be handled by your ACCTINFO=1 code. Some, however,
will not. SYSOUT sent from a non-z/OS system such as
VM will only produce SMF record sets consisting of one
or more SMF type 6 records and an SMF type 26 purge
record. The following ACCTRTE sample code handles
these situations where ACCTINFO=0.
SAMPLE ACCTRTE EXIT
This sample account routine exit code is for a company
with three account codes. The three account codes are
defined in sharedprefix.MICS.PARMS(ACCOUNT) as follows:
*
* ACCOUNT CODE STRUCTURE
*
1 3 Division
2 5 Dept
3 8 User
4 1 Unused 4
5 1 Unused 5
6 1 Unused 6
7 1 Unused 7
8 1 Unused 8
9 1 Unused 9
ACCTNO1 holds the Division, a three-character field.
ACCTNO2 holds the Department, a five-character field.
ACCTNO3 holds the User ID, and eight-character field.
ACCTNO4-9 are defined but unused.
The Division and Department values are specified in the
job card. User ID is set from the RACF User ID field.
Started tasks (PGMTYPE=3), have valid RACF User ID
values but no job card account fields.
This site has created two SAS formats, $GOODDIV and
$GOODDPT that contain all valid division and department
values for the company. These two formats return a
value of YES if the division or department value is
valid.

IF PUT(TEMPDIV,$GOODDPT.)='YES' THEN
ACCTNO2=TEMPDPT ;
END ;
IF SMF26UIF NE ' ' THEN ACCTNO3=SMF26UIF ;
END ;
The most notable thing about this sample ACCTRTE exit
code is that overhead values are assigned first. The
overhead values are only overwritten if valid account
code information is encountered. By using this
technique you can systematically identify observations
written with overhead account codes, determine why they
received overhead values, and make appropriate
adjustments to your ACCTRTE.
Use the worksheet in Figure 7-2 to code your account code
exit routine (ACCTRTE).

SYSTEM ADDRESS SPACE PROCESSING CONSIDERATIONS
The first time a new address space is encountered with a
unique JOB/RDRTS combination, ACCTRTE executes. At
this time, a job initiation record (SMF type 30 subtype 1) is
expected. It contains the job card (ACTFLDx fields) required
by ACCTRTE.
When ACCTRTE is executed, the ACCTNOx variables are populated
with the ACTFLDx field values, and a flag (ACCTFLAG) is set
to 1 in the BAT_JS (Batch Job Activity Suspend File) to
indicate that this address space has been through ACCTRTE,
and the ACCTNOx field values have been established. When
ACCTFLAG equals 1, the address space will not go through
ACCTRTE again. Once the address space has gone through
ACCTRTE, and the ACCTNOx values are established, they are
preserved in the BAT_JS file, and merged with new
step/interval records in subsequent executions.
If ACCTRTE code is updated, address spaces that have already
gone through ACCTRTE, and address spaces that are still
executing, would be immune from any ACCTRTE updates. The
BAT_JS01 record for the address space will propagate the
ACCTNOx values set using the old ACCTNOx code.
To take advantage of the ACCTRTE updates for system address
spaces, there are two options:
1) IPL. This option restarts system address spaces, which
would consider them as NEW, and thus go through
ACCTRTE.
2) Copy BAT_JS01 from the production complex to a test
complex, and run a job to recreate the BAT_JS01 file:
DATA DETAIL.BAT_JS01;
SET DETAIL.BAT_JS01;
(additional code)
Additional code can be either of the following:
a) The updated ACCTRTE code for system address spaces
to reestablish new values in ACCTNOx field. In a
test unit, run an update using the updated
BAT_JS01. The updated ACCTNOx values
propagate to the BAT_SA file observations.
b) Code to change the value of ACCTFLAG from 1 to
0 in the BAT_JS01 file for system address spaces
(JOBTYPE=6). Run an update using the updated
BAT_JS01 file. The updated address spaces are
forced to go through ACCTRTE.
