A customer has a large RAC installation but business pressure is now requiring the IT group to really deliver High Availability for their database.
The problem is that current crop of CPU patches have included OJVM patches which require a downtime. Customer is not happy that they have to take an outage even after implementing an MAA.
Are there any options for getting away from the downtime for applying OJVM patches? As per doc Id 1929745.1, OJVM patches cannot be applied in Rolling fashion in a RAC environment nor in a Standby First in a dataguard setup.
How about using GoldenGate to keep a standby database copy updated which can be shutdown for patch application and then brought up and the applications switched to that db? It will also probably need some application downtime to switch but I am assuming that is much smaller than 3-5 hours which the customer goes through every quarter.
Thanks in advance.
