Hello,
We have here the SAP ECC 6.0 running on AIX 7.1 and Oracle 11G with 24G SGA. When we was configuring the oracle parameter, we've checked the note 1627481 regarding how to size the log_buffer an it suggests us to unset this parameter since we have 80 cpu's. So, we have reset this parameter and now i've checked it and the current value is around 80MB. I've read that the log_buffer since Oracle 10G is dynamic calculated by a internal algorithm (Oracle note 604351.1). In many forums i've read that setting the log_buffer beyond 1M we have no benefits since log write writes, among other situation, when log buffer reaches 1/3 full or 1M.
In my situation, is OK let the log buffer "dynamic".
Is right the way i've interpreted when SAP said to unset the log_buffer when systems with more the 16 cores? unset = reset in this case?
Obs.: this system is really busy with around 1500 users connected simultaneous.
