Log file parallel writes






Hi all,

In a Oracle 9i RAC database in Solaris ,the log file parallel write event
in Statspack has around 30,000 waits and log file sync has around
15,000.There are 4 logfile groups with 2 log members in each group and the

size of each is 100M. and all the 4 groups are in the same file system.

Will reducing the number of redo log groups to 3,multiplexing across the
available file systems and increasing their size have any improvement.

Thanks.


Kind regards,
Raj
