Hi Marcia,

Why does he "need the entries stored in the cache"?

Where is the entry held? If it's a local entry, or you're on a World Search 
node, or a Copyall node, then the entry won't be placed into the cache.

Are the lookups being done from MBMAN, or something else like ALL-IN-1?

Hi,

   The machine is not a world search node neither a copyall. They are 
consulting dds from teamlinks and ALL-IN-1 . But I have already done a search 
from mbman and the entry wasn't stored at the cache either. 
   They want some entries stored in the cache because they are very accessed 
and if I use an entry that is stored locally or that there is in the cache, in 
 teamlinks, the address is returned very fast , if not, the search is done and 
the user complains about the time it delays. He is complaining because these 
entries are not being stored in the cache.

And this customer has 24 entries that are very accessed and these are the 
entries that he would like to have in the cache but that are not there and we 
can't understand why.

   Marcia

I don't know either. It seems that ALL-IN-1 and TL should be updating the 
cache - you can enable a couple of events ( 5.29, 5.30) to see if you're 
accessing the cache. MBMAN doesn't cache entries, but you're not seeing them if 
you do a mbman show dds subsc .../noworld/cache ?

Anything in dds$log.dat?

Otherwise you might have to wait for Dave to pass through.

    To cache an object, the application has to do a search, and then issue
    a particular call to "touch" the object in the result set; 'touching'
    the object can have a variety of differant effects, but in the case in
    .2 would result in it being cached. The question that needs be answered
    is 'Under what conditions (if any) does your particular mail client
    trigger the "touch" operation?'. I don't know the answer to this for
    Teamlinks; I can confirm that MBMAN never 'touches' results.
    
    I have a vague recollection that the DMW server arbitrarily 'touches'
    the first N results (10? 50?). I _think_ the VT client for both DMW
    and ALL-IN-1 'touch' the result selected for a To: mail address. For 
    a definitive answer you should ask the ALL-IN-1 or DMW conference.
    
    BTW, the MBMAN SHOW command to search the cache exclusively should
    use the /noperm switch.  eg  MBMAN SHO DDS SUB/NAME=*/NOPERM
    (SHOW defaults are /perm/cache/noworld)

Hi Dave,

     For sure that SHOW DDS SUBSCRI/NOWORLD/CACHE doesn't return the 
object because I 've already tried it. I didn't use /noperm , but as the 
entry wasn't found, it doesn't matter I guess , because this means 
that the entry is not in the perm database neither in cache ... right ? 

     I'll see if the events are enabled and if not I'll enable and check 
the dds$log.dat because I know some entries that are in the cache and I 
can choose them and choose the ones that are not to see what happens in 
the log.

     I'll update this note as soon as I can do this test , because 
probably I'll have to enable these events and I guess the customer won't 
let me stop dds to reconfigure it during the afternoon.

     Thanks ,

    You don't need to shut it down though it will require a Suspend/Resume.
    
    MC MBMAN
    	SET DDS CONFIG/LOGE=(5.29,5.30)
    	ACCEPT DDS CONFIG
    
    Dave

Hi Dave,

 Thanks . I didn't know this command. I'll try it this morning because I 
checked yesterday and the events 5.29, 5.30 are not enabled. 

 Another information that I forgot to tell is that they don't have ALL-IN-1 on 
the same node of message Router. Their ALL-IN-1 runs on an alpha and  uses 
remote message router.

    re: commands in .6
    
    They are undocumented (though described in the MR Support Guide).
    
    re: remote DDS access
    
    Shouldn't make a difference; the remote DDS interface supports 'touch'.
    
    Dave

Hi Dave,

    It worked. I enabled the events and realized that when I made search from 
teamlinks, nothing happened but I tried from ALL-IN-1 , using the addresses to 
send a mail and the entries went to the cache. I guess I  missed a step last 
time I tried. 

   Thanks for the help. 

   Is there any way to disable the events 5.29, 5.30 without stopping DDS ? 

   Marcia 

     

    I'm surprised Teamlinks isn't touching *anything*.
    
    MC MBMAN
    	SET DDS CONF/IGNOREEVENTS=(...
    	ACCEPT DDS CONFIG
    
    Like I said, this stuff is in the MR support guide.
    
    Dave

Thanks Dave,

    I didn't have this support guide but I copied yesterday.
