5. www.uvsoftware.ca Why Migrate to Unix/Linux ? Increase Performance Reduce Cost: –Linux systems less expensive than proprietary Mainframes Reduce Risk: –migrating existing systems is less risky than rewrites or new package implementations Preserve legacy logic: –Proven & customized over many years

14. www.uvsoftware.ca COBOL porting to Micro Focus Not much to do, but saves manual editing Insert EXTERNAL on select/assign stmts Translate to lower case except in quotes –more modern appearance –easier to edit with unix/linux editors (vi,etc) Insert detail file status test code –For Micro Focus extended file status display

15. www.uvsoftware.ca Data Conversion Translate EBCDIC to ASCII –Preserving packed/binary fields –Correcting zoned signs to ASCII standards Conversion jobs generated from copybooks –and LISTCAT file specs 1 script to generate all conversion jobs 1 command to convert all data files

16. www.uvsoftware.ca Data Conversion Example Data conversions generated from copybooks Sample copybook (citytax1.cpy) CobMap record layout from copybook Sample cobmap (citytax.map) Data conversion job (uvcopy) Sample uvcopy data conversion job (citytax1.uv)

17. www.uvsoftware.ca Data File specs from LISTCAT LISTCAT info completes conversion jobs –Info added to copybook/cobmap/uvcopy job –Data filename, file type, Indexed keys Sample LISTCAT & extracted control file uvcopy job completed by control file

18. www.uvsoftware.ca Converting flat files to RDBMS Convert data to pipe delimited text files –Packed/binary fields edited signs & decimal pts Packed/binary fields unpacked & edited –Conversion jobs auto-gen’d from copybooks SQL loader control file also generated Sample pipe delimited output file Sample uvcopy job to perform pipe delimit Sample loader control file
