5.10 Removing the DAYSMF Step from the DAILY Job

During CA MICS DAILY processing, the DAYSMF step is used to
split SMF data into separate data sets for each component
that has SMF data as input.  This helps to reduce I/O, CPU
time, and execution time because each component processes
only the SMF data it requires.

Instead of using the DAYSMF step in the CA MICS DAILY job, CA
SMF Director or other processes can be used to split the SMF
data into discrete data sets outside of the CA MICS DAILY
job.

CA MICS supports this configuration by allowing the DAYSMF
step to be removed from the DAILY job and allowing the
installation to specify the input data sets of the SMF data
for processing by each component.

The following checklist shows the steps necessary to
deactivate the DAYSMF step and manually specify the input
data sets for components that use SMF data.

__  1. Determine components in the unit that use SMF as an
       input data source

       MICSLOG message BAS10083 in any JCLGEN lists the
       components that have SMF as an input source. The
       following will regenerate the JCLGENU job with JCLGEN
       to identify the components that use SMF data as input.

       Edit prefix.MICS.PARMS(JCLGENU) and make sure it has
       the following line in it:

       JCLGENU

       Save prefix.MICS.PARMS(JCLGENU).

       Submit prefix.MICS.CNTL(JCLGENU). This job should
       complete with a return code of zero.  Review the
       MICSLOG and locate message BAS10083.  This message
       lists the components that use SMF data as input.

__  2. Deactivate the DAYSMF step

       Edit prefix.MICS.PARMS(JCLDEF) and find the DAYSMF
       keyword and change it to:

       DAYSMF OFF

__  3. Specify input data set for each component

       For each defined component that has SMF data as an
       input source, a prefix.MICS.PARMS(INPUTccc) member
       must exist.  If the INPUTccc member does not exist, it
       must be created or the CA MICS DAILY job will not
       generate.

       For each INPUTccc, a DD for INPUTSMF or SMFDRCTR must
       be added or modified. Use this example for SMF input:

       //INPUTSMF DD DISP=SHR,DSN=SMF.SPLIT.DATASET

       Use this example for CA SMF Director input:

       //SMFDRCTR DD DISP=SHR,DSN=CA.SMF.duplicate.index

       Note:  When running with DAYSMF OFF,
       prefix.MICS.PARMS(INPUTRDR) will be used to specify
       the input data source for the component step if it is
       the only remaining SMF eligible step.  That is, the
       only component in the unit using SMF as the input
       source.

__  4. Generate the DAILY job

       Edit prefix.MICS.PARMS(JCLGENU) and add the following
       line:

       DAILY

       Edit prefix.MICS.CNTL(JCLGENU) and submit the job for
       execution. This job should complete with a return Code
       of zero.

       If the JCLGENU fails with a user abend of 998 and
       the following message:

       BAS10117E MEMBER INPUTccc INDICATED ON A ":INCLUDE" OR
                 A ":INCLUDEPARM" STATEMENT NOT IN LIBRARY

       then the INPUTccc member was not created per step 3.
       In this case, create the member; then run the
       prefix.MICS.CNTL(JCLGENU).

__  5. (Optional) Delete SMF work data sets

       When the DAYSMF step is present, an SMF work data set,
       prefix.MICS.ccc.DATA (where ccc is the component
       identifier), is created for each component that uses
       SMF data. This data set is either temporary or
       permanent, depending on the value of JCLDEF keyword
       DAYSMF.

       Since the DAYSMF is no longer being used, these
       data sets are not required and may be deleted.


Note:  If the input data set names for a component change,
the INPUTccc members, or INPUTRDR, can be modified and the
DAILY regenerated using JCLGENU.
