hi

what is difference between commit and fast commit internal operations.

I know at commit server process takes the transcation scn increments it and put it in the log buffer along with commit marker. server process singals the lwgr to write log buffer from the last scn to the commit scn to the redo log file and commit is complete.

with fast commit it delays the writing to redo file and writes in batch sound strange

Can anybody tell me how fast commit work internally
