Hello,
Given the following configuration:
* Server with 12 SPARCVII CPUs and 96 GB of RAM
* ZFS used as file system for Oracle data
* Oracle 10.2.0.4 with 1.7TB of data and indexes
* 1800 concurrents users with PeopleSoft Financial
* 20000 PeopleSoft transactions per day
* HDS USP1100 with LUNs stripped on 6 parity groups (450xRAID7+1), total
48 disks
* 2x 4Gbps FC with MPxIO
Which is the best Oracle SGA size to avoid cache duplication between
Oracle and ZFS?
Is it better to have a "small SGA + big ZFS ARC" or "large SGA + small
ZFS ARC"?
Who does a better cache for overall performance?
Thanks in advance and best regards,
Javi
