Please correct me if I'm wrong but as far as I can tell DFSORT only queries the system about paging activity BEFORE starting the sorting process, to decide if it should use additional memory (ie. data space or memory objects sorting) to help performance but otherwise virtual storage remains constant throughout most of the sorting process (with DFSORT to adjust the storage up to the DSA limit depending on the input data being sorted ).
Only the size of the data space or memory object is adjusted dynamically as necessary, in response to system paging levels. Regards, Yi Ming >Why? The sorts use virtual/main very efficiently. I think I read that >both will actually adjust if there is a system paging problem. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
