Hardware Clustering VS Oracle Hot Standby


We want to implement high availability (via hardware clustering) for our SAP Production Database server.

  • The server is Sun-Solaris with Oracle database.

  • The server is shared: ECC5.0 ERP Database and SRM4.0 Database

  • The central instance for ERP and SRM each run on a separate Windows server. We would like to move the CI's to the Database server, to further reduce single point of failure and reduce problems of heterogenous landscape.

  • ERP and SRM have been live for over a year.

Question 1:

Documentation appears to indicate that clustering must set up as a step during the SAP installation. Is there any way to configure Sun clustering without reinstalling SAP, or do we have no choice?

Question 2:

In consideration of other high availability options, we are toying with the concept of "Oracle Hot Standby". Can anyone comment if this would be a viable alternative to hardware clustering? With limited resources, we are looking for the best option, cost-wise and time-wise.
