    init.ora of TPC-C world record database

    I was skimming the TPC benchmark disclosure report at http://www.tpc.org/results/FDR/TPCC/...050412_FDR.pdf

    Thought folks might be interested in the init.ora of the database. Tons of undocumented parameters..

    well a totally unrealistic parameter file - shows how worthwhile those tests are

    Not a _go_faster = true in sight. I always knew they weren't telling us everything.

    and one control file .....

    and if i read that right a 14gb shared pool and 176gb buffer cache

    and an undo retention of 1 second

    pile of junk...

    LOL wonder what would happen if someone were to take that init.ora bring the memory stuff down to reasonable levels then throw it on a test box to see what would happen.hmmmmmmm
    Oracle it's not just a database it's a lifestyle!
