The CA MICS JCL generation (JCLGEN) process is accomplished
by a series of jobs. When run, these jobs create the job
streams and JCL procedures needed to install and run CA MICS.
The JCLGEN function is divided into small jobs in order to
separate functions which will be performed with greater or
lesser frequency. The function of each of these jobs is
shown below.
JCLGEN0 - Complex-wide jobs and clists
JCLGEN1 - CA MICS Accounting and Chargeback specific jobs
JCLGEN3 - CA MICS Templates Used in Q&R Workstation
JCLGENA - Database Unit Installation Jobs - Part 1
Note: This job is copied from
sharedprefix.MICS.CNTL(JCLGENA) by the
COPYLIBS job. JCLGENA generates the same
JCL as JCLGENB and is used only during
creation of a new database unit.
JCLGENB - Database Unit Installation Jobs - Part 1
JCLGENC - Database Unit Installation Jobs - Part 2
JCLGEND - Database Unit Operational Jobs
JCLGENE - Jobs Affected by a DB Split After Installation
JCLGENF - SPECIAL Database Unit Installation Jobs
JCLGENG - SPECIAL Database Unit Operational Jobs
JCLGENUC - Regenerate Complex Jobs from a User Supplied List
JCLGENU - Regenerate Unit Jobs from a User Supplied List
Note: The consolidated UNITGEN process is a combination of
JCL, MACRO, and DATABASE generation processing that
consolidates most CA MICS generation processes for a
database unit into a single batch process. The
UNITGEN job generates (and optionally submits) the
UNITGEN1 job to perform, in a single batch process,
the JCL generation processing of the JCLGENB, JCLGENC,
and JCLGEND jobs, along with the COPYLIBU, ALLPGEN,
CYCLEGEN, and GDGSGEN processing for a unit database.
See section 5.6 for more information on the UNITGEN
process.
The process flow of complex level JCLGEN is illustrated in
Figure 2-15.

Figure 2-15. Complex Level JCLGEN Process Flow Input consists of the user-modified JCLDEFC, USERJCL, JCLINFO, JCL$Iccc, JCLNAMES, and CPLXDEF members of sharedprefix.MICS.PARMS; all selected (GENLIST) prototype job stream (JCL), procedure, CLIST, and MACRO members from sharedprefix.MICS.PROTOLIB; and the CA MICS-provided definition tables from the sharedprefix.MICS.PARMS, GENLIB, and ISPTLIB libraries. These definition tables contain lists of jobs to be created (JCLGENx and JCL$xccc) along with definitions for data set names (JCLNAMES) and job attribute (JCLINFO and JCL$Iccc) specifications. The default tables cause the creation of all jobs and must be used the first time you do a JCLGEN. See Section 2.3.3.3.2.1, Job/CLIST Generation Lists, for a more complete description of these lists. JCLGEN may generate any number of job streams (JCL), procedures, CLISTs, MACROs, and ISPF table definitions. These outputs are placed in the CA MICS CLIST, CNTL, MACAUTOS, ISPTLIB, GENLIB, and MCOLIB libraries. The process flow of a unit level JCLGEN is illustrated in Figure 2-16.

Unit Level JCLGEN Process Flow Input consists of the user-modified JCLDEF, USERJCL, JCLINFO, JCLNAMES, DBSPLIT, SITE, EXECDEF, and the INPUTccc members of prefix.MICS.PARMS; all JCL$xccc GENLIST and all JCLINFO and JCL$Iccc members of sharedprefix.MICS.PARMS; all selected (GENLIST) prototype job stream (JCL), procedure, CLIST, and MACRO members of sharedprefix.MICS.PROTOLIB; and the CA MICS-provided definition tables from sharedprefix.MICS.PARMS, sharedprefix.MICS.GENLIB, and sharedprefix.MICS.ISPTLIB. These definition tables contain lists of jobs to be created (JCLGENx and JCL$xccc) along with definitions for data set names (JCLNAMES), job attributes (JCLINFO and JCL$Iccc), database split (DBSPLIT), site characteristics (SITE), and dynamic execution options (EXECDEF) specifications. The default tables cause the creation of all jobs and must be used the first time you do a JCLGEN. See Section 2.3.3.3.2.1, Job/CLIST Generation Lists, for a more complete description of these lists. JCLGEN may generate any number of job streams (JCL), procedures, CLISTs, MACROs, CA MICS parameter members, and ISPF table definitions. These outputs are placed in the sharedprefix.MICS CLIST, CNTL, MACAUTOS, ISPTLIB, GENLIB, MCOLIB, and SOURCE libraries. Output is also placed in the prefix.MICS USER.SOURCE, MUOLIB, and PARMS libraries.
