IMS V8/DB2 Coordinated Disaster Recovery
- IMS/DB2 Coordinated disaster recovery support: The IMS Remote Site Recovery (RSR) function is extended to provide support for coordinated IMS/DB2 disaster recovery by working with XRC (eXtended Remote Copy) for the DB2 logs. Without this support, if IMS and DB2 logs, log control information, and (optionally) database data to a remote site by independent transfer mechanisms, the customer has to synchronize the IMS and DB2 logs and ensure that the IMS and DB2 databases are consistent when a disaster occurs. This can be a time-consuming and error-prone process and puts data integrity at risk. The new support enhances IMS RSR for coordination of IMS and DB2 disaster recovery processing at a remote recovery site, offering an IBM-provided solution for synchronizing the logs. In the supported configuration, XRC is used for DB2 logs. With this support, the steps required by the user to synchronize the logs are greatly reduced.
