Logical Standby Database an implementation

Introduction

For my colleagues at Atos I have set up a Presentation of my experience with the Logical standby database. Since I truly believe in modern media like Twitter and sharing knowledge via the Web this one has to be put out here as well. As always  you have to investigate if my approach can be yours as well. And as a quote that I have learned on the web, never regard every challenge as a nail requiring only a hammer.

One main point I have to make is that the complete set up was performed using sqlplus . I did not use the broker at first when setting things up. And as often once you choose a direction .. Looking back now and reading posts on twitter it would have been an interesting twist to do the same while using the broker. Maybe that can be your challenge and after that there will be a nice blog coming  from that too then.

Happy Reading,
