WIO is very high !! how to reduce it?

[marist89]

so, so you think you can tell a good datafile layout from a bad one, heaven from hell, blue skies from pain?

How can you tell? enlight us, please.

How many you want to talk about?

How about the client that had both sets of redo log members on a single RAID 5 device?

Or, how about the client that put their TEMP and UNDO tablespace on the same filesystem?

Or, how about the person that put DATA on one filesystem and INDEX on another?

It's hot in hell, comfortable in heaven.

C'mon man, don't be naive...
