Hi Friends,

I have researched a bit on fail-over options with Oracle 11G R2 RAC on 
RHEL 5.4 ( two node)

TAF can be configured in server side or client side. I think there is some 
limitation in configuring FAILOVER_MODE= PRECONNECT in server side [ID 
460982.1], where it supports only BASIC at the moment. I would also like 
to have an expert  recommendation on which configuration to use BASIC / 
PRECONNECT.

I am also confused as whether I should use TAF / FCF . I saw a few 
materials describing configuration and tests for FCF on jdbc layer, 
wondering if there is someway to setup FCF in server side ?

After all, which one is better  - FCF / TAF ?

I could not see any recommendation from for Oracle for this, Or Am I 
missing something here ?

Thank You,

Kind Regards,
Sreejith Nair
