4.1.2 Operational Processes, Jobs, and Steps
An operational process is a series of batch jobs that make up
a logical unit of work. Operational processes update and
maintain the CA MICS Database.
There are four operational processes in CA MICS:
o DAILY process - the DAILY job followed by the BACKUP
job
or optionally
one or more SPLITSMF (optional) and
INCRccc jobs followed by the DAILY job
and the BACKUP job.
o WEEKLY process - the DAILY job followed by the WEEKLY
job followed by the BACKUP job
o MONTHLY process - the DAILY job followed by the MONTHLY
job followed by the BACKUP job
o YEARLY process - the DAILY job followed by the YEARLY
job followed by the BACKUP job
CA MICS provides standard operational jobs for updating,
reporting, maintaining, and recovering its database:
o DAILY - run each day to update the DETAIL and DAYS
timespan files plus week-to-date and month-
to-date files in the WEEKS and MONTHS
timespans
o INCRccc - (optional) run one or more times a day for
each product for which you have activated the
CA MICS incremental update facility. The
INCRccc jobs update the product's incremental
update DETAIL and DAYS level files, which are
then "rolled up" to the DETAIL and DAYS
timespan files by the DAILY job.
o SPLITSMF - (optional) run one or more times a day to split
the SMF input data into multiple files for
processing in the INCRccc jobs. SPLITSMF is a
stand-alone version of the DAILY job's DAYSMF
step and applies only to those products which
take their input from the SMF files, and which
are marked as INCRUPDATE YES and INCRSPLIT USE
in prefix.MICS.PARMS(cccOPS).
o WEEKLY - run once each week after the DAILY job for
WEEKS timespan cycle close-out, weekly
archive audit, and weekly archive history
processing
o MONTHLY - run once each month after the DAILY job for
MONTHS timespan cycle close-out and monthly
archive history processing and for updating
year-to-date files
o YEARLY - run once each year after the MONTHLY job for
YEARS timespan cycle close-out
o BACKUP - run daily, bi-daily, or weekly (per user-
specified backup frequency) to generate a tape
backup of the entire database
o SCHEDULE - run each day to submit scheduled processing
o RESTORE - run whenever the database is damaged or must
be recovered
o AUDIT - (optional) run after WEEKLY to perform optional
Archive Audit processing. The AUDIT job is
used when you specify
ARCHIVE AUDIT YES JOB
in prefix.MICS.PARMS(JCLDEF).
NOTE: You can execute AUDIT more frequently
(e.g., twice a week or daily) if DASD
space is inadequate for retaining
sufficient DETAIL/DAYS cycles for weekly
audit tape creation.
In this case, it is necessary to add the
following to prefix.MICS.PARMS(EXECDEF)
USERDEF AUDITCWK YES
This parameter overrides the default
audit archive processing so that data
for the current week is retained and
copied to the new audit archive tape
cycle.
o HISTW - (optional) run after WEEKLY to perform optional
Archive Weekly History processing. The HISTW
job is used when you specify
ARCHIVE HISTW YES JOB
in prefix.MICS.PARMS(JCLDEF).
o HISTM - (optional) run after MONTHLY to perform
optional Archive Monthly History processing.
The HISTM job is used when you specify
ARCHIVE HISTM YES JOB
in prefix.MICS.PARMS(JCLDEF).
o IUDBINIT - (optional) run to re-initialize in-progress
incremental update processing after restoring
the unit database files (i.e., after running
the RESTORE job). Messages in the RESTORE job
MICSLOG will prompt you to execute IUDBINIT
when needed.
o DAILYRPT - run after DAILY to produce daily production
reports
o WEEKRPT - run after WEEKLY to produce weekly production
reports
o MONTHRPT - run after MONTHLY to produce monthly
production reports
o RSTRTBLS - run to restore the TABLES and SCREENS data
sets
o RSTRTLIB - run to restore ISPF-based information
o DAYSMFR - run as necessary to recreate DAILY job work
files normally populated by the DAYSMF step.
o ACTDAY1R - run as necessary to restore the CA MICS
Accounting and Chargeback DAY1 audit file
o RSTATUS - run as necessary to update Operational Status
and Tracking control tables or to replace a
lost Run Status Report
These jobs are generated as part of the installation process
because each job is tailored to the installation's
environment. Individual CA MICS products may also generate
additional operational jobs for unique, product-specific
processing.
The CA MICS operational jobs in each unit database are
unique. Job steps are defined based on the products
installed in the unit. For example, the DAILY job for a unit
that contains the Hardware and SCP Analyzer (step 20,
component identifier RMF) and the Batch and Operations
Analyzer (step 30, component identifier SMF) would contain
the following steps:
o DAYALL - allocates work file space
o DAYSMF - selects and splits SMF input data to work files
for processing by Database update steps
o DAY020 - updates the RMF product Database files
o DAY030 - updates the SMF product Database files
o DAY200 - updates exceptions (EXC02nnn for RMF and
EXC03nnn for SMF)
o DAY400 - submits daily report processing
o DAY500 - processes non-standard user reporting, if any
o DAY900 - terminates the daily job and frees work file
space
o DAYRSR - produces the Run Status Report
CA MICS operational jobs are built by unit and made up of
independent steps for the following reasons:
o Reduced run time. Separate jobs for each unit enable
CA MICS Database updates to run concurrently. For
example, for a complex containing two units (unit A
having the SMF, RMF, and SNT analyzers and unit B having
the IMS and DB2 analyzers), unit A's update can be
processed while unit B is being updated, because the
units are independent.
If the units were dependent, the time needed to update
the database would be greater, because unit A would need
to complete its processing before unit B's could begin.
NOTE: With the CA MICS incremental update facility,
individual product incremental updates can execute
concurrently with incremental updates for other
products in the unit database. However,
end-of-day processing for the unit database is
still a serial process, and if the units were
dependent, unit A would need to complete its
end-of-day processing before unit B's could begin.
o Input data independence. Separate jobs for each unit
enable Database update scheduling based on input data
availability. In the prior example, unit A's update can
be processed before the IMS and DB2 input data used to
update unit B are available.
When all products are installed in a single unit
database, no updates can occur until ALL input data is
available.
NOTE: With the CA MICS incremental update facility,
individual product incremental updates can occur
when the product's data becomes available.
Individual product incremental updates are
independent of any other product's processing in
the unit database. However, the end-of-day, DAILY
job, can not execute until ALL products are ready
for end-of-day processing.
o Flexibility. The ability to restart after a failure at
the job step that failed saves:
- Time, because the work that had been completed prior to
the failed step is retained
- Resources, because the system does not reprocess work
it had successfully completed
For example, if an operational job fails part way through
processing due to an I/O error with the input tape, the
work completed in prior steps is retained and the job can
be restarted at the step that failed when the error is
corrected.
If CA MICS operational jobs were not step-restartable,
the entire run would be lost. In a unit database that
contains multiple products, this loss could be very
significant.
