Secures data connectivity during infrastructure failures The DB2 High Availability Feature provides 24 x 7 availability for your DB2 data server through replicated failover support and data recovery modules. The three packages that comprise this feature bring one unique aspect of high availability to the data server environment. This feature consists of the High Availability Disaster Recovery (HADR), the Online Reorganization feature and IBM Tivoli System Automation for Multiplatforms (SA MP).
Together with the HADR, Online Reorganization and SAMP modules, the High Availability Feature offers a complete solution for organizations that cannot afford to lose connectivity to their data servers or have their database applications down. HADR allows failover to a standby system in the event of a software or hardware failure on the primary system. Online Reorganization reconstructs the rows in a table to eliminate fragmented data and compact information for better performance while permitting uninterrupted access to the table data. SA MP provides high availability by automating the control of IT resources such as processes, file systems, IP addresses, and other resources. It can coordinate the automatic failover to a standby DB2 data server using HADR.
