    Are you seeing a bottleneck? Do you need performance?

    the only reason I ask these questions is that some folks over here like to
    make changes when they aren't warranted and sometimes put us at risk for no
    good reason.

    If it does not need to be recoverable, what hurt is there if it is
    protected? Where are cursors going to be stored and sorts going to be done
    if the temp table space is lost ?

    In oracle I have temporary tablespace that does not need to be recoverable.
    Currently I have it as a raid 1 (mirrored) but I am thinking I might get
    better performance with a raid 0 (striped) accross 3 disks. The current
    configuration has this datafile on a mirrored raid array which has 2 6230
    adapters but my striped array is on a single 6230. Both have write cache.
    What is your opinion?

    thanks.
