Description:

This book is an indispensable reference for any Oracle DBA who must ensure the consistency of data across distributed platforms. With the advent of cheap disk and fast worldwide connectivity, many Oracle professionals recognize the benefits of distributing Oracle data. However, Oracle multi-master replication is extremely complex and time-consuming to implant. This book addresses the complexity of Oracle replication by providing working code examples and illustration from working systems. The text covers all areas of Oracle replication, including snapshots, using dbms_job to refresh snapshots, multi-master replication and conflict resolution mechanisms.

Written by a distinguished graduate of West Point, Col. Garmany leverages his 20+ years of experience into an indispensable guide for any Oracle professional who must quickly implement Oracle snapshot and multimaster replication. A noted instructor, author and lecturer, Col. John Garmany leverages his ability to explain complex issues in Plain English into a one-of-a-kind book.

This handy reference contain working examples of snapshot and multimaster replication to allow you to get started quickly with your Oracle replication structure. Packed with useful notes and an online code deport, this reference show every aspect of Oracle snapshot replication including syntax for refresh intervals, managing snapshot logs, monitoring Oracle replication refresh timings and much more.

Best of all, this is the only book that describes the intricacies of Oracle multimaster replication and provides working code examples of complex multimaster replication. Includes a section on Oracle replication tuning and monitoring, this is a must-have book for all Oracle professionals who replicate their data.
