Hi All,
In a Cobol-DB2 program, I am fetching rows from 4 tables
using cursor and then based on the a field present in that
table, It processes the information accordingly..for
example stat-c is one digit field..if stat-c is 'D' then
the a row is deleted from table and written those details
in to a file. If the stat-c is 'U' then a row is updated
(hardcoded what to update)in a table and written those
details in to a file. If the stat-c is 'I' then a row is
inserted in a table and written those details in to two
files. The issue is i have to include the intermediate
commits. When an abend occurs, due to commit statement db2
tables will be saved, But there will be lose of file
contents. When we resubmitting the job associated with this
program there will be insert ,update and delete anomolies
to avoid that what measures could be taken?.
The intermediate commit is nothing but issuing
commit after massive inserts, updates and deletes(sum of
500actions)

Track the count of records processed and modify your cobol program so to take the input of no of already processed records. When you restart the job make sure that you pass the count and cobol program will start processing from the next record of the file.
