1) Create two work files, say WORK-1 and WORK-2.
2) Unload the table into file WORK-1.
3) Pass the commit frequency through the JCL to the program.
4) Program logic:
(i) read the input file WORK-1
(ii) update the table
(iii) if the number of records updated in the table is
equal to the commit frequency then apply COMMIT command.
Also, write the last committed record into the output file
WORK-2. (this record will be used for restart logic)
(iv) In Restart process,
a. read the output file record
b. next, the input file will be read untill it
finds the corresponding output file record
c. follow the same step 4(i) to step 4(iii)
