Hi All,

This is Ramesh kumar. I have a doubt, please clarify.

Background of doubt:

================

Assume I am using 10g/11g database. Purposefully as DBA I kept a tablepsace called X in hot BACKUP mode. A user connected to the database and doing some DML transactions on tables that are existing on the same tablespace called X. User is performing a huge DML transaction not ye commited or rolled back the transaction. At this situation if Database buffer cache filled, Oracle flushes the dirty block to log buffer, log buffer to redo logs and if the transaction still continues and a log switch occurs the data/blocks will be written even to corresponding data file even. After long

Howdy, Stranger!
