OTN Appreciation Day: Oracle Data Guard and DG Broker
Thanks to Tim Hall for organizing this day – I’m happy to give back to the community which has given me so much.
My favorite feature is with no doubt is the Data Guard.
Even though the Data Guard feature might looks like an excess of other features (redo log for recovery, archive log for backup) it is one of the more awesome features in the Enterprise Edition database.
For those of you who don’t know what I am talking about – Data Guard is the disaster solution feature for the Oracle Database. This feature has been around since Oracle 7 (under the name Standby Database), but in Oracle 10g it had a major change: for the first time there was a way to create disaster recovery solutions, which actually had ROLES in them!
