Hi,
We have a customer who is interested in moving their existing infrastructure to an Active Active Database configuration, they have several SAP systems including ECC, CRM and PI. They currently have an Oracle database clustered in one data center and then use Oracle Data Guard to replicate the database into a 2nd DC. Now they want to configure the Database as Active Active across the data centers, they want always on set up, just in case they lose one of the DC's so that they wont lose the database for the minutes to hours for fail over to the 2nd DC that they currently have.
We are looking at Extended RAC across the DC's but this will also mean additional Network upgrades so its looking quite expensive, any other options?
thanks
Simon.
