Resolving The Problem

This document explains how to estimate how long your next GO SAVE Option 21 will take.

Data area QSRSAV21 in QUSRSYS contains information about the last five GO SAVE Option 21 (Save Entire System) operations.

    • - Example



      Issue the following command:

      DSPDTAARA DTAARA(QUSRSYS/QSRSAV21)

    Using the example listed above, you can determine the following about the full save done on 12/04/2011:

    20111204051052 SAVSYS     TAP06  <--SAVSYS started at 05:10:52 on 12/04/2011 and took about 16 minutes to complete
    20111204052632 SAVLIB     TAP06  <--SAVLIB started at 05:26:32 on 12/04/2011 and took about 3hrs 8 mins to complete
    20111204083428 SAVDLO     TAP06  <--SAVDLO started at 08:34:28 on 12/04/2011 and took about 6 seconds to complete
    20111204083434 SAV        TAP06  <--SAV started at 08:34:34 on 12/04/2011 and took about 1 hr 16 mins to complete
    20111204095008 SAVIASPS   TAP06  <--SAVIASPS started at 09:50:08 on 12/04/2011 and completed under a second
    20111204095008 ********          <--GO SAVE 21 job completed at 09:50:08 on 12/04/2011 and took 4 hrs 40 mins to complete

    Notes:
    1. The data in bold is the date with format YYYYMMDD.
    2. The six digits after the date is the time the save command started with format HHMMSS.

    The information in the QSRSAV21 data area includes the following:

    o Starting date and time of each major step in the save operation
    o Step identifier
    o Device used.

    The ending date and time of the save operation is identified with asterisks.

    You can use this information to help you estimate how much time to allow for your next GO SAVE Option 21 operation.
