    Possible to extract all records in one Voyager process?

    Question

    Customer needs to extract all the records in the database (250,000+).
    Is there a way to do this in one extract process instead of running multiple sequential extract processes?

    Answer

    Yes.
    Selective Extracts using BIB range, specify an optional parameter at the command line to break the extract into multiple threads (-T).
    The BIB range will be divided into that number of threads, with each thread extracting its assigned subset of the range.
    Each thread should extract no more than 250,000 records.

    Additional Information

    Example: A database has 500,000 records and the highest bib_id is 526778. All can be extracted in a single process with the command

    /m1/voyager/xxxdb/sbin/Pprimoexp.sel -f ../ini/PrimoExp-Selective.ini -B1 -E526778 -T5

    and 5 threads, extracting ~100,000 records each would run in the single process.
