I have an instance that is waiting on log file synchs. I suspect that the waits are a result of a overly large redo log buffer. There are also considerable waits on direct path writes. The redo logs are on QuickIO, so I assume that the writes LGWR is writing asynchronously and not a source of the log file synchs. I want to be sure that the log file synchs and direct path writes are not related before I begin to experiment with the size of the redo log buffer. How can I be sure that the waits are being caused by DBWR and not LGWR? What are possible fixes for the direct path writes if it is the DBWR causing them? Multiple DBWR? The datafiles are not on QuickIO, just the redo.
