    Description:
    How long does p_union_02 take to run? How many processes should it have? Can it be run in a parallel library?

    Resolution:
    p_union_02 took 16 hours to process 3.8 million records at one library under version 18.

    The job will run faster with more processes -- I would say up to two times the number of processors -- up to a max of 20. (Of course, it will also take more resources from other processes.)

    Though the Parallel Indexing document doesn't mention it specifically, it seems to me that p_union_01 and _02 could be run in a parallel library without any problem.
