1) I have 3 programs : PGMA, PGMB, PGMC. PGMA calls PGMB and PGMB calls PGMC. I have to do inserts, updates in all the 3 pgms. 2) Say PGMC has done its work successfully and returned to PGMB 3) PGMB had an SQL error while doing some update 4) PGMA has already done some updates before calling PGMB all are running under the same CICS region. What will happen if I issue SYNCPOINT ROLLBACK in PGMB when it abends ? Does all the changes in PGMA,B,C rollback ? (because all the pgms belong to same task).

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)
