Oracle Performance Tuning on AIX

1) Depending on your version, you may need to set filesystemio_options=setall (in 10g and 9i)

2) Make sure mount file system of data file, control file and redo logs with option "-o cio"

3) Create the filesystems for redo logs with -o cio and agblksize=512

4) Plan on increasing your db_cache_size to compensate for the loss of file
system buffering at the OS level

5) set lock_sga=true

6) use AIX large memory pages (e.g. 16M with vmo -p -o lgpg_regions=2048 lgpg_size=16777216)
