Biography

As businesses become more web and e-commerce-enabled, high availability computing solutions are becoming increasingly important because of the extremely high cost of application downtime. According to a Gartner Group study, the cost of outages for corporations involved in e-commerce can easily reach millions of dollars per hour. Therefore, database availability and manageability have become increasingly important in many of today's mission-critical environments. One way to enhance availability and manageability is to allow users full access to the database during a data reorganization operation. Oracle's DB DBMS_REDEFINITION is a compelling package used to 'online redefine' tables. Online redefinition of a table means that changes (inserts/updates/deletes/merges) can be made to the table while modifications to the data are being made. Join this session to understand the key benefits of Online Data Reorganization and Redefinition.
