Just pulled up this info from Oracle Docs.... Well, If you could give some
inputs as to the performance issues that u r facing bacause of this - it
would be useful. Also, what type of application are u running?
Here is the info:
*********************
Reducing Contention for Redo Copy Latches
On multiple-CPU computers, multiple redo copy latches allow multiple
processes to copy entries to the redo log buffer concurrently. The default
value of LOG_SIMULTANEOUS_COPIES is the number of CPUs available to your
Oracle instance.
If you observe contention for redo copy latches, add more latches by
increasing the value of LOG_SIMULTANEOUS_COPIES. It can help to have up to
twice as many redo copy latches as CPUs available to your Oracle instance.
