1524.0. "When is archive clean up?" by SWETSC::WESTERBACK (Panta rei) Mon Apr 21 1997 07:59

    We're trying to understand the data flow for PCM (1.6 for VMS)
    but there seems to be some piece missing.
    
    Data is first stored on console$logfiles. It's transferred to 
    console$archive in two situations:
    
    1) Planned archiving, data before "keep" time is archived
    2) Auto archive, when File Space critical threshold as defined
       in the configuration (show filespace) is reachedfor the logdisk, 
       then the oldest hours (as defined in show archive) are moved to 
       archive disk.
    
    But next step is a bit unclear. There is an action routine called
    console$actions:CONSOLE$ARCHIVE_CLEANUP.COM, which by default
    deletes archive files that were created more than two days ago.
    But when is this started, it seems an event CMgr Archive Area Full
    triggers it, but when does this event occur? Is it when the disk
    is 100% full? 
    
    It seems to me that this routine runs regularly without the disk being 
    full. I have set up the archive cleanup time to be 10 days, and all my 
    archive files disappear after that time, and my archive disk always seem 
    to be around 40% full. Is there something setup that I'm not aware of 
    that starts archive cleanup at 40% full? Is there any logfile kept for 
    the archive cleanup?

    So far so good...

    Here's the missing piece Hans. The CMgr Archive Area Full triggers the
    action routine when the disk that contains the *archive* area is %100
    full. The event triggers when the Archive interface detects the archive
    disk is full.

    Someone could have modified the Archive Area Cleanup filter to trigger
    on somehting other than the Cmgr Archive Area Full event. Someone could
    have also added the action to another filter by mistake. The point here
    is that somone would have had to have modified something.
    
    There is no logfile kept as it's an action routine. You can customize
    that action routine in any way you wish. You don't even have to use
    it if you do not want to. You will need to setup a job to monitor and
    clean the archive area on a regular basis if you have a requirement
    to keep X days/weeks/etc. of on-line console data.
