Thanks for this link, I read abt oracle 9i concept but I didn't find answer for

which process checks, whether any process is working or not.

I read that checkpointer is responsible to tell DBWR to write changes. But if checkpoint gets corrupted ( kill it manually with kill command or anyhow ) how will instance come to know abt it. What I know is checkpointing depends on parameters ( FAST_START_MTTR........... ).
Will checkpointer revert back to instance that checkpointing is completed in a particular time.

I thank you to tell me this link. I read it, and hope it will solve my many doubts as well as it helps me to understand 10g. So Thanks again. Received on Tue Jan 16 2007 - 23:22:52 CST
