I have a subprogram B calling from mainprogram A.I have
opened a cursor in A ,Can i fetch the same cursor in
subprogram B , If yes , Please explain the reason?
Answer / harsha
I feel yes, we can fetch the same cursor in the same
program.
Cursor can be closed in three ways.
1 When you explicitely close trhe cursor.
2 Issuing commit systement.
3 After execution of an application program.
In our situation, none of the above mentioned case is
getting true.

How can record locking be achieved in those DB2 versions which do not support it?
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)
