IBMDB2I storage engine is designed as a fully
featured transaction-capable storage engine that enables MySQL to
store its data in DB2 tables running on IBM i. With the
IBMDB2I storage engine, data can be shared
between MySQL applications and applications coded for native DB2 for
IBMDB2I provides ACID-compliant transactions,
support for foreign key constraints, full crash recovery,
radix-tree-based indexes, and the unique ability to allow DB2 for i
applications to see and update table data in real time.
More information about the storage engine and its interaction with DB2 for i can be found in IBM's Using DB2 for i as a Storage Engine for MySQL Redbook publication, at IBM DB2 for i a Storage Engine for MySQL Redbook.
