5.0 von 5 Sternen Oracle Data Guard Administration 26. Juni 2013
Von Michael C Seberg - Veröffentlicht auf Amazon.com
Format:Taschenbuch
Rich with real world examples including logical Standby setup. Has a great best practices section and common issues section.
The details on how to patch a Data Guard system are excellent and are probably worth the price of the book alone. There are plenty of Advanced Techniques included. Well done!

Chapter 3 starts mentioning pre-requisites before a logical standby database implementation. This chapter states and explains most of the options available to configure verify and monitor a successful logical standby database.

Chapter 4 introduces the Data Guard Borker, it clearly shows its components, benefits and the DGMGRL tool. This chapter shows also Data Guard Borker setup and how it is used to change dataguard configuration and database proprieties. The chapter has a very good section about troubleshooting Data Guard Borker, Tracing and most common broker issues. Authors also explain about the Fast Start Fail over (FSFO) and the Observer.

5.0 von 5 Sternen Oracle data guard 11gr2 beginners guide review notes 26. Juli 2013
Von J. madan - Veröffentlicht auf Amazon.com
Format:Taschenbuch
The Book is very well written, precis and up to the point. The authors seems to be well versed with Oracle
Data guard technology and experience in the same field oozes out in their writing.
The data flow diagrams in the book are well defined and helps in understanding the flow from primary to standby database ( I would have liked to have color patterns in them ).
Here are few other suggestions from my point of view.
I like oracle data guard evolution from version 7.3 stone age to version 11g modern age described in chapter 1.
In chapter 1 LNS ,RFS ACK acronyms meaning should have been described earlier than they are for the reader to understand them at the earliest.
Page 19 Apply spelled wrong as Aapply
Page 20 wrong use of like operator it should either use % or use = operator
on page 21 it's better to use scope=both or scope=spfile for permanent change or scope=memory or instance only change.
The book describes how logical data guard can have different user schemes than production. This is very important aspect for a DBA to replicate the production data for using it for reporting while use logical standby for other ODS purposes and save cost for the company.
The book also describes how to skip/unskip tables and whole user schemes. This is important aspect for DBA to customize and manage logical database as well as save space and cpu cycles by avoiding replication of unnecessary staging tables.

SQL> alter system set log_archive_dest_2='SERVICE=TEST_STANDBY LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=TEST';
on Page 38 Section Time for action - enabling the archive log mode It is better to set log_archive_dest parameter so that archive log are create at a desired location and not default location which will fill up oracle binaries mount point.
