Answer / s
Transactions are programs that run under the transaction
managers like CICS, IMS/TM. Transactions require excellent
response times.
Commit makes the database changes permanent that was made
during a unit of recovery ie. from one consistency point to
another.
Rollbacks reverses the changes made to the database during
a unit of recovery.

How does the processing of a correlated subquery differ from a non correlated subquery?
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)
