1668.0. "Logical Links and .file directive to remote node" by KERNEL::COOPER (Suzanne Cooper UK Customer Support (833)3502) Tue Oct 27 1992 16:42

    
    Within an entry form you can specify a .file directive that points to a
    data file on a remote node i.e. wayout::oa$data:wombat.dat,key.  You
    can use this file but when you come to exit the entry form the decnet
    logical link is left open and only closed once the user has exited
    ALL-IN-1.  Is there any reason for this and is there a way round the
    problem?  The reson I ask is that a customer is complaining about the
    number of logical links being used on his system and never being closed
    down.
    
    As an aside I have tried manually disconnecting the logical link in NCP
    but that seems to cause a problem whereby ALL-IN-1 thinks the link is
    still there and say's it can't find the file and never tried to reopen
    the link. 
    
    I'm sure this problem has been around for years but I can't seem to
    find it anywhere, can someone confirm or deny my fading memory?  

ALL-IN-1 keeps track of recently or frequently accessed data sets and 
caches, or keeps them open, to improve performance.  The DUMP_CACHE 
function flushes all data sets that ALL-IN-1 has cached and therefore 
closes the file.

I suspect that the data set is being cached and thus the file and DECnet 
logical link is remaining open.  The DUMP_CACHE function will accept an 
option parameter to specify the name of the data set you want flushed from 
the cache.

Clarification:  DUMP_CACHE entryformname

for application datasets which use an entry form to access the dataset.
