    Active Active DR for eBS R12.2.4

    user11970066

      Has anyone implemented Active-Active DR for the Oracle eBS Application ?

       

      The objective is to ensure that the users are redirected to the DR automatically in case the Primary site is not available for a specific time. There should be no manual intervention required.

       

      Looking forward for a active participation from the oracle community

          You can implement Maximum Availability Architecture for EBS which is close to Active-Active.

          Basically you will have to provision exact replica of your Production Site (All servers) into DR Site and enable Active DataGuard with Fast Start failover. This will eliminate the need for manually switching your Database from Primary to Standby and can get your Standby environment up and running all Automated within few minutes. Of course it will depend on latency between your Primary and DR side.

           

          Here you go with few of the great articles on this topic.

          Good Luck !

            I need to know more about the eBS application switchover ?

            How do I achieve that ?

            Data Guard would help achieve the failover of the Database but not the application.

             

            How do I integrate the R12.2 eBS Application on the DR site once the Failover of the Database has been completed?

              The MAA architecture has a configuration which relies on stretching the weblogic cluster across to your DR site. However, not every product is supported on a stretched weblogic cluster, so you will need to check each component of EBS to see if it is supported on a stretched cluster.

              An alternate is to have two separate weblogic domains on each site, but then you will have a challenge to keeping both domains in sync. DataGuard will not work so well in this scenario since it keeps the database in sync but each domain's config is also partially stored in the database and that is not the same.
