Hi, I need advice here.
I created databases on our x3 full rac environment. DB version is 11204.
I did a exachk, and it shows this warning:
The database machine provides extremely high redo generation rates that may make you consider increasing the log file sizes. Following initial deployment, the online log file sizes should be 4GB each.
My current redo log size is 1g, old non-exadata rac envrionment redo log size is 500m.
This environment has huge data, and a lot OLTP plus query , so it is kind of mix environment.
How do I be sure the redo log size is optimal and where should I place the redo logs? On what kind of disks? flash disk or regular disks?
THanks in advance.
