    Hi,

    My oslevel is 5300-07-01-0748 and it's ok when I try to use the command sar without any parameters, however when I tried to use the '-s' parameter I got error messages:

    #sar -s 13:00

    "
    ...
    System configuration changed. The current iteration values may be inaccurate.

    sar: There is not enough memory available now.
    "

    Any clues please?

    This happens when you upgrade your AIX (i.e. changed /unix) and forget to reboot so you are running the previous version of /unix in memory.

    Have you updated recently or could you take a reboot?

    I suspect this because the command will look are the wrong bit of the kernel for numbers and then try a allocate many GB's of memory for the data structure instead of KB and generates the "not enough memory" errors.
    I would also expect other performance tools to show weird results.

    Hey,
    We recently had a number of issues with sar, both different type on differeny servers.
    Good news is there is a patch available from IBM Fix Central that fixes it straight away. No reboot required and it works perfectly after that.
    Check out APAR IZ14802. Theres a number of APARs all sar related that this is the fix for.
    Let me know if this fixes your problem.
    Regards.
