  Re: what is commitment control?explain about it?
Answer
# 1
The DB2 UDB for AS/400 commitment control support provides
a means to process a group of database changes (updates,
inserts, DDL operations, or deletes) as a single unit of
work (transaction). A commit operation guarantees that the
group of operations is completed. A rollback operation
guarantees that the group of operations is backed out. A
commit operation can be issued through several different
interfaces.
