Are you using filesystems? If you are you need to turnoff filesystem buffering at the Solaris level. If you are using UFS you need to set the mount option "forcedirectio". If you are using VxFs then you would use "mincache=direct, convosync=direct". Do this on all the filesystem that contain your datafiles.
