Coordinated Recovery for IMS, DB2 and VSAM

In many large data processing organizations, applications have evolved and established relationships between IMS and DB2, but don't forget VSAM. Sometimes these relationships are known to the application (as in the case of a two-phase commit process), but frequently it's a more casual relationship. A transaction in one database management system may spawn a subsequent transaction in a different database management system. The transactions are tied, but the log data isn't coordinated. BMC Software offers an alternative process for obtaining a recovery point. This process ensures data integrity after system-wide recovery, yet it requires no outage to establish a System Wide Point of Consistency (SWPOC). This unique process is built on the intelligence and innovation in BMC Software's recovery products for IMS and DB2. Using exclusive BMC Software technology, it's possible to capture information from the recovery repositories and use it to derive a consistent and coordinated recovery point. The probable use for this process is in support of disaster recovery (DR), but some applications (for example, large ERP applications with correlated legacy applications) may make use of the procedure for local recoveries.
