These messages in given alert log were full checkpoints caused by log
switch.
Incremental checkpoint is an ongoing process, there really isn't a number
of
them - in essence it's just CKPT process checking how far DBWR is with
it's
writings and updating this info in controlfiles every 3 seconds.
*Incremental* checkpoint entries in alert log are just status messages on
checkpoint progress as far as I know, not individual checkpoint completion
messages.
