Project Done at SSC Board for Porting on AS/400
Project Name : Porting of Programs and Data from ICL Mainframe to AS/400
Platform : IBM AS/400 with V4R3 O.S and COBOL/400 & CL/400
Client : Maharashtra State Higher Secondary School Examination Board
Team size : Five
Legacy application in COBOL running on ICL's Mainframe 1904 since 1983 was successfully ported on AS/400 in time limit of 45 days. The application consists of forty COBOL programs consisting of heavy user interactions and complex logistics and huge data. Processing of Examination results of about 2 million students all over Maharashtra state is done with this system.
Technical Details of Implementation
All flat files are converted to physical files on AS/400 and not required indexes are dropped.
All screen sections were converted to subfiles.
Alternate Collating sequence is used, as default AS/400 sorting uses EBCDIC.
OS/400 and DB2/400 were tuned to allocate maximum resources to programs.
CL programming is done to automate the process.
