Oracle Database Failover Active/Passive Unix/Linux Plataform – Free of Charge
Posted: 08/05/2012 Filed under: 10g R1, 10g R2, 10g R2, 11g R1, 11g R1, 11g R2, 11g R2, ASM - Automatic Storage Management, Clusterware / Grid Infrastructure, Database, Oracle 1 CommentIn this post I will show you how to setting up environment high availability without the option Oracle RAC.
Oracle Fail Safe is available only for Windows, for Unix / Linux would need third party software Cluster to do the Failover.
Good News From Oracle:
Oracle Clusterware
Oracle Clusterware provides cluster membership and high availability services. It provides the cluster membership for features such as Oracle Real Application Clusters and Oracle ASM. It includes the following features:
- Application monitoring, restart, and failover
- Cluster membership services
- Server monitoring and fencing
- Single Client Access Name (SCAN)
- Server Pools
- Grid Naming Services
Oracle Clusterware can be used to protect any application (restarting or failing over the application in the event of a failure), free of charge, if one or more of the following conditions are met:
- The server OS is supported by a valid Oracle Unbreakable Linux support contract.
- The product to be protected is either:
- Any Oracle product (e.g. Oracle Applications, Siebel, Hyperion, Oracle Database EE, Oracle Database XE)
- Any third-party product that directly or indirectly stores data in an Oracle database
- At least one of the servers in the cluster is licensed for Oracle Database (SE or EE)
A cluster is defined to include all the machines that share the same Oracle Cluster Registry (OCR) and Voting Disk.

See step by step here using clusterware 11.1, we can improvise this setup to 11.2 using SCAN feature which is more easy.

Hi Levi,
have you tried to create active/passive failover cluster using 11.2 clusterware following steps from specified document for 11.1 (creating resources, resource groups)?
Can crs_stat, crs_relocate, crs_start/stop, etc. be used in 11.2 clusterware as in 11.1 or there is another more preferred way for managing resources?
Thanks for answers.
Regards,
Marko
