2. HORIZONT 2 XINFO ® Incremental update for Source Scanner 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? It is prerequisite for incremental update that your standard job is running without problems.

3. HORIZONT 3 XINFO ® 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.

5. HORIZONT 5 XINFO ® First possibility : Job XXRJCOBU PGM XXRCCOB to analyze Cobol-Sourcen members which should be scanned

6. HORIZONT 6 XINFO ® First possibility: Job XXRJCOBU input SourceLibs input CopyLibs output PS-datasets

7. HORIZONT 7 XINFO ® First possibility: Job XXRJCOBU PGM XXRITGN to manipulate data in DB2 update scanned records

8. HORIZONT 8 XINFO ® First possibility: Job XXRJCOBU update these tables in DB2 parameters are described in: XINFO z/OS Tips and Tricks input PS-datasets

9. HORIZONT 9 XINFO ® Second possibility: Job XXRJISC project which should be scanned called REXX:create Files with Checksums or ISPF-Stat create a list of all members

10. HORIZONT 10 XINFO ® Second possibility: Job XXRJISC created member which must be scanned rows to be deleted

11. HORIZONT 11 XINFO ® Second possibility: Job XXRJISC list with all members which must be analyzed output PS-datasets PGM XXRCCOB to analyze the source

12. HORIZONT 12 XINFO ® Second possibility: Job XXRJISC delete actual records from DB2 delete rows from tables PGM XXRITGN to manipulate data in DB2

13. HORIZONT 13 XINFO ® Second possibility: Job XXRJISC records to be updated update DB2-tables PROC XXRJ2LOA to load the records in DB2

14. HORIZONT 14 XINFO ® Second possibility Job: XXRJISC rename Work-Files: …PROJECT1.DEL: modules to delete …PROJECT1.OLD: list of modules and libraries with ISPF-Stat + checksum …PROJECT1.SCN: parameters for cobol scanner, including MEMBER=Statements …PROJECT1.WTR: list of modules which are using changed copy members

15. HORIZONT 15 XINFO ® Second possibility: Job XXRJIFC compare the checksums with old files project which should be scanned (see Job XXRJISC) called REXX to identify the files with new Checksums

16. HORIZONT 16 XINFO ® Second possibility: Job XXRJIFC list only with members that must be analyzed output PS-datasets PGM XXRCCOB to analyze the source

17. HORIZONT 17 XINFO ® Third possibility: Job XXRJILC compare the checksums with your own member list project which should be scanned (see Job XXRJISC) called REXX to identify the files with new Checksums

18. HORIZONT 18 XINFO ® Third possibility: Job XXRJILC Your own member list list with your own members that must be analyzed

19. HORIZONT 19 XINFO ® 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.

20. HORIZONT 20 XINFO ® Job XXRJMSP0: Unload Records from DB2 new output PS-Dataset qualifier must be equal to input PS-Dataset in Job XXRJMSP

21. HORIZONT 21 XINFO ® Job XXRJMSP: Create new list input PS-Dataset.unload qualifier
