How data is stored in both IMSDB and DB2 databases?
Some business applications require that the data is kept in both IMS and DB2 for z/OS databases. One such scenario is a high-performance production application that works with the data in an IMS database and a business decision support application that works with the same data in a DB2 for z/OS database.
Production applications running in IMS Transaction Manager (IMS TM) can update data that is stored in a DB2 for z/OS database and data that is stored in an IMS database. If not performed in a single, logical unit of work, coordinating these updates can be complex.
