Incremental update for Source Scanner
It is prerequisite for incremental update that your
standard job is running without problems.
To get the results that you want, the following
improvements of quality should be done before using the
incremental update:
• Which Source Libs and Copy Libs belong together for one
“project”? Is there a meaningful relation of “Source Libs
and Copy Libs"?
• If there a duplicate include members: Do you know the
correct order of libraries?

Incremental update Source Scanner
There are three possibilities to do incremental update
1. If you want to scan one or a few specific program members,
you can directly use Job XXRJCOBU (e.g. started from a
hand over system)
2. To (e.g. daily) update XINFO with all changed source
members
-
Use XXRJISC/P to create a basic-list for all source-members
and their ISPF-Statistics or “checksums”
Use the (daily) Job XXRJIFC/P to find out which members have
changed ISPF-Statistics or “checksums” and doing the scan.
3. If you have a dataset with a list of changed members, you
can take only the Job: XXRJILC/P for incremental update
With 2. and 3.: If a Copy-Member is changed, all affected
source members are scanned automatically.

Effects on Programs-Data
• If you use incremental update, the data for
“Programs-Tables” are not filled updated.
• You can use the sample job XXRJMSP0 to
unload the current data from DB2. The job
creates the files used by Job XXRJMSP, but with
an additional qualifier: ...UNLOAD
• Either copy the steps in XXRJMSP0 into
XXRJMSP or edit XXRJMSP to use these files.
• The rest of the job can be used without
modifications.
