Every now and again it is necessary to brush up on previous skills in order to resolve problems.
Today I'm going to get down to a handy Oracle features which is called Oracle Data Guard.
Since Oracle database 7.3 version, this features has been introduced and it offers the possibility to protect database from failure, disaster, human error and data corruption.
Since the first version, lots of new options have come out like for example in the 11g, the 'Active Data Guard' and what's more the 'Snapshot Standby'.
In my opinion, the first step to do is the installation of a complete Test environment made up with a Primary and Standby database server and what's more since the last production environment is a Oracle 10GR4 release this post will end up installing a 10GR4 primary and standby databases.
See you soon.
Byeeee
