    Question about relocatable resources
    "We have the relocatable threshold set at 85% for most of our storage
    pools.
    Our ADSO SYSGEN statements include the following:
    - FAST MODE THRESHOLD IS OFF
    - RESOURCES ARE FIXED

    When a pool exceeds 85% full, will any storage ever be written to
    scratch with this combination? How can I tell if it is?

    "We are running with system snaps on, even in production. So CA will have
    something to work with
    DIS SNAP

    *** DISPLAY SNAP REQUEST ***

    SYSTEM SNAP STATUS IS ON (ENABLED)

    SYSTEM SNAP PHOTO STATUS IS OFF (DISABLED)

    TASK SNAP STATUS IS OFF (DISABLED)

    TASK SNAP PHOTO STATUS IS OFF (DISABLED)

    V16 ENTER NEXT TASK CODE(PRD/IDMSP):


    So in case of system program checks or CV crashes the system generate an
    SVC dump which can be analysed by CA via IPCS

    think it will

    "Hi Chris,

    I have to agree with Gary, our shop runs with snap off, we turn it on if
    we need a dump. Also we run with COLLECT only for statistics, really
    saves a lot of I/O and anything that does that reduces response time.

    Re: BIUA event on May 5 2006 presentations.
    "One of the problems with the DC-Log is single threading - so if you're writing out a system snap this can take a while and other tasks can end up waiting. The other problem is just the additional IO. Having said that - this is clearly only a problem while you're actually writing out system and/or task snaps. So if you don't generate many of these it's not much of an issue. We run with snaps OFF - and sometimes this works against us because if we have a problem we would like CA to work on - we don't have much for them to work with - and sometimes it hard to recreate the problem. We are very sensitive to how much we put out to the log and have turned off the ""report printed"", ""user logged on"" and ""user logged"" off messages (changed their routing in IDD) to reduce traffic. Another thing to watch out for is that some people think that they need TASK STATISTICS WRITE to get Perf Mon stats to work - all you need is COLLECT instead of WRITE. With WRITE on you send task stats to the LOG as well as wherever you tell perf mon to send them in the #PMOPT - usually to SMF - so you've got them in both places. If you have WRITE turned on you are killing your system with single threaded IO to the log.
    That's just our position on the log - others might take a different stance.
