Services in multiple standby databases

edited Oct 23, 2015 10:01AM in High Availability Data Guard, Sharding and Global Data Services (MOSC) 2 commentsAnswered

Is there a way to manage read only workload across multiple active data guard databases -

Version 12.1.0.2 or 11.2.0.4

Single Instance Primary – for online transactions and batch

3 single instance standby databases for different reporting modules

Under normal operation condition, when all 4 databases are available they will handle different areas of application workload using 4 different services. But since services can only be configured based on roles in single instance data guard configurations, I am looking for help on below

  • - configure services on 3 standby databases so that each service starts/runs only on one standby database at a time
  • - configure services that can relocate to other available standby database in data guard configuration.

Howdy, Stranger!
