hi Jarek P
Yes,you are rigth, there are lot of activity on the disk because there are lot of dmls running.
Actually there are 4 arvhiver processes and they dont't access the same disks,in fact they are access RAID5 disks.
"The solution would be to either extend the size of redo logs or add another 1 or 2 redo log groups. This would alleviate the situation."
I don't know if add more redo log groups will solve this problem. There are five log groups already.Do u think adding more log groups can solve the problem?

From above log we can see that it only takes 51 secs to switch from log 5 to log 4
. We find that there are lot of redo entries produced. Do u think this is normal?

Do u think the log buffer is too small regarding the redo size produced per second( 891,704.80/s)
Thank u!
