I'm building a Dataguard test environment to validate if it is possible to have a configuration where:
Option 1 seems to be validated by SAP (1431241 - RAC with TAF) for RAC, thus should be ok with Dataguard.
This has already be documented by Kjell Erik Furnes in this great POC: HA SAP on Oracle DataGuard
I'm just a bit concerned about the problem with the FAILOVER_MODE option set to PRECONNECT that is according to Kjell making failover quicker but is not compatible with R3trans (should use BASIC mode as stated in note 562403 - FAQ: Oracle Net)
For option 2 I did not find any 'official' information from SAP.
Note 105047 - Support for Oracle functions in the SAP environment tells that the Data Guard Broker is supported but I did not find any information about FSFO except Oracle documentation Oracle White Paper—Setting up Oracle 11g Data Guard for SAP customers (page 8).
So is FSFO fully supported/validated by SAP?
Does anybody ever use FSFO + TAF?
Thanks for you feedback,
