Hi,
I am getting messages of incremental checkpoint in my alert logs with some scn.
Completed checkpoint up to RBA [0x125de6.2.10], SCN: 445135162445
Does this mean that all dirty blocks which have had their initial changes before this SCN(445135162445) will be written to disk so that instance recovery can begin from the SCN from which checkpoint has completed.Or is it the other way like the incremental checkpoint has occured at scn 445135162445.
