How to quickly build standby database and setup DataGuard configuration using Oracle 12c

With every release of Oracle database there are new possibilities to build a required solution (ex. standby database) faster and with fewer steps. This is not official guide but rather a mix of Oracle 12c functionality used to build DataGuard configuration using RMAN and DataGuard Broker.

Assumptions:
  • There is a database which will be used as primary.
  • New listener will be added to support standby traffic

Steps to run on primary database

An AMIS Overview of Oracle Database 12c

The presentation used during the highly successful AMIS Oracle 12c Launch Event is online for those who are interested. Enjoy. Special thanks for Thomas Kyte; for allowing me to use some of his pluggable database presentation content. An AMIS Overview of Oracle database 12c (12.1) from Marco Gralike

DataGuard – Far Sync – part 1 – simple configuration

Oracle introduced a new feature for DataGuard called Far Sync. This configuration is design to support synchronous redo transport between primary and standby database which are far apart. In usual configuration synchronous redo transport between data centre in Europe and US is possible but inefficient from the primary database performance perspective. Every commit has to be written locally to redo logs and send to standby with confirmation – a network round trip between Europe and US is a significant delay for every commit operation in synchronous mode.

Oracle 12c - incremental backup for DataGuard over network

If you have DataGuard or standby database in your organization you probably will love that new RMAN feature. Since 12c it is possible to catchup standby database using incremental backup using one command. Additional space and time need to run incremental backup, copy over to standby and restore can be limited to time required to run incremental backup over network.

See short example:

Stopping recovery on standby
