    Gather Schema Stats

    I have an error in my db alert file
    Performance statistics empty: data overflow
    I conclude that it is due to statistics are not available so we have to gahter statistics periodicaly but i am afraid that when we analyze table then perhaps information about these analyzed these tables cached in database buffer cache bocome invalid then is that true? that these object reloads will occur
    is that true? that performance degrades

    no the buffer cache is not invalid, however all cursors in the shared pool will become invalid and queries will be re-parsed.

    but that isnt a problem realy
