Good morning friends
I'd like to ask about some points in oracle RAC.
- About failover, how long time to complete failover ?(power off first node and power on the vip address on second node)
- In general, how do you measure the "failover time" ?!
- In general, how do you test the Failover in RAC environment ?!
- I have been configured the environment RAC 10.2.0.3 with TAF (preconnect). Can I think in HA if my application was developed without code to HA ?!
- With RAC and TAF environment, the "select * from dba_tab_columns;" command for example will work fine or will stop when the node is power off !? (the node which I'm connected from sqlplus)
- About TAF configuration, It's necessary configure only on client, only on server or in both (Server and Client) ?!
- There are any recommended configuration to HA !? (change about time of service or RAC cluster)
Thank you so much in advanced.
Cheers
