3.1.1 Implementing SMS Accounting
Follow this checklist to implement resource usage charges for
SMS (System Managed Storage) using the CA MICS VCA Analyzer
and CA MICS Accounting and Chargeback.
___ 1. Ensure that CA MICS Accounting and Chargeback is
installed in each CA MICS unit that contains the VCA
Analyzer.
If you are using CA MICS Accounting and Chargeback in
a production environment, we recommend that you
implement your SMS algorithm in a test unit before
modifying your production CA MICS unit(s).
___ 2. Consult your DASD Administrator or Systems Programmer
to determine the SMS Storage Class and Management
Class values in use at your installation. You will
need to be informed if these values change. Verify
that the VTOCs of all packs containing data sets to
be charged are scanned and input to the CA MICS DASD
Space Analyzer.
WARNING: CA MICS Accounting and Chargeback uses the
Storage Class field to determine if a data
set is managed by SMS or not. Normally,
all non-managed data sets have a blank
value for Storage Class. If your
installation uses an exit or other means to
populate Storage Class for non-managed data
sets, they will be charged in the ACTJMS
SMS journal file, according to your SMS
algorithm, if it is active.
___ 3. Determine the rates per megabyte hour to be used for
each Storage Class and for each Management Class.
___ 4. Determine whether you wish to charge from the VCA
Analyzer files at the DETAIL or at the DAYS
timespan. Modify prefix.MICS.PARMS(VCAOPS) so that
it contains one of the following statements:
ACCOUNTING DETAIL
or
ACCOUNTING DAYS
The DSNAME, DSNODE, and VOLSER variables are only
present if you use the DETAIL timespan. If you do
not need to reference these variables in your COSTRTE
exit, and if you do not need a separate record for
each data set in the journal files, you can use the
DAYS timespan.
Submit prefix.MICS.CNTL(VCAPGEN) and ensure that it
completes with condition code 0.
Perform this step for each CA MICS unit that contains
both the VCA Analyzer and CA MICS Accounting and
Chargeback.
___ 5. Select Option 5, Charging Element Definition, from
the Accounting Parameter Specification and Generation
Menu.
Locate the SMS computation codes (1830-1836 and 1840-
1850). Codes 1831-1836 and 1841-1850 are shipped
with the phrase "Value n" in the Description and Unit
fields. Select each computation code that you will
use and modify the Description and Units fields to
specify a Storage or Management Class value used at
your installation.
For example, suppose your installation uses two
Storage Class values, Specific and Standard, and
three Management Class Values, LARGE, STANDARD, and
CRITICAL. You would need to modify the Storage Class
computation codes 1831 and 1832, and the Management
Class computation codes 1841, 1842, and 1843 to
reflect these values instead of the phrase "Value n".
HINT: Once you select a computation code, you can
scroll DOWN (or UP) to position the display to
the next (or previous) code.
You do not need to submit the CHRGELEM generation job
at this point. It will be run when you submit the
MAGRUN job in the next step.
___ 6. Select Option 6, Rate Table, from the Accounting
Parameter Specification and Generation Menu, and
select the desired unit database.
Select the ACTJDA VCA journal file and make sure that
it contains the algorithm(s) (computation codes and
rates) that you will use to charge any non-managed
data sets.
HINT: After you select the journal file, choose
Option 3 from the Journal File Options menu
and a list of algorithms will be displayed.
Select each algorithm to review or modify it.
If you have more than one algorithm, you will
need to use Option 4 to qualify them.
Select the ACTJMS VCA journal file. Review the
sample Journal File Specifications (Option 1) and the
sample SMS algorithm (Option 3). The algorithm
contains the following two lines:
Comp Control
Code Rate Variable Comp Code Description
---- ---- -------- ---------------------
1830 0 STORCLAS CHARGE FOR DEFAULT STORAGE CLASS
1840 0 MGMTCLAS CHARGE FOR DEFAULT MANAGEMENT CLASS
This means that each SMS data set will be charged as
follows:
Data set charge = megabyte hours * Storage Class rate
+
megabyte hours * Management Class rate
NOTE: CA MICS Accounting and Chargeback uses the
variables STORCLAS and MGMTCLAS as the
control variables in this algorithm. These
variables are assigned from the VCA variables
STORSTGC and STORMGTC, respectively.
Specify the rate for default storage class on the
STORCLAS line. Then select this line to display the
Variable Values Specifications panel. Enter a rate
for each computation code you are using and delete
any other rows.
For example, if you are using computation codes 1831
and 1832 for Storage Class values of SPECIFIC and
STANDARD, you will modify the rates on these lines
and delete the lines for computation codes 1833 and
1834. The default computation code and rate will be
used to charge any other Storage Class values that
are encountered.
Now specify the rate for default management class on
the MGMTCLAS line. Then select this line to display
the Variable Values Specifications panel. Enter a
rate for each computation code you are using and
delete any other rows.
Submit the MAGRUN job when you END from the Rate
Table and ensure that it completes with condition
code 0. Review the MICSLOG to ensure that it ends
with the BAS00172I message GENERATION PROCESS
COMPLETED SUCCESSFULLY.
Review the Schedule of Rates report produced by the
MAGRUN to verify your computation codes and rates for
the VCA journal files.
Perform this step for each CA MICS unit that contains
both the VCA Analyzer and CA MICS Accounting and
Chargeback.
___ 7. This completes the implementation of your SMS
charging algorithm. The ACTJMS journal file will be
created in the next CA MICS DAILY run; you should
review the Journal Run Status Log (MWF;4;2;4;5;1;1)
to validate the charges.
You can also refer to the Daily Charges Summary
Report by submitting prefix.MICS.CNTL(BGTCNTL). The
Storage Class charges are reported under invoice
category 7230, and the Management Class charges are
reported under invoice category 7240.
Refer to Section 3.1.2 for information on how to
audit your DASD charges.
