NAME

       mkatfs - create and configure AtFS object repository and derived object cache

SYNOPSIS

       mkatfs  [-cAmax_cached_per_cacheattr] [-cNmax_cached_per_name] [-cTmax_total_cached] [-cQ] [-ggroup] [-h]
       [-lpath] [-mmode] [-v] pathnames

DESCRIPTION

       mkatfs may be used to create an AtFS object repository, to link an existing repository,  to  configure  a
       repository,  or  to  set  the  size  attributes of an derived object cache. It applies to all directories
       occurring in the pathnames list. If the list  is  empty,  mkatfs  performs  its  action  in  the  current
       directory.

       Creating  an AtFS object repository makes a directory named AtFS with several files and subdirectories in
       it.

       The -l option causes mkatfs to link an  existing  AtFS  repository  to  the  current  directory  (or  the
       directories  in  the pathnames list).  The -l option expects a pathname to a directory containing an AtFS
       repository or a link to an AtFS repository (links may be chained) as argument. When linking a repository,
       mkatfs either creates a symbolic link or, if symbolic links are not available  on  your  system,  a  file
       containing the name of the target directory. The latter will be interpreted by AtFS like a symbolic link.

       Configuring  an AtFS repository means, that the group and the protection may be changed. These operations
       perform a chgrp(1) and a chmod(1) operation on the AtFS directory and all its subdirectories.

       The -cT, -cN, and -cA options set the size of the  derived  object  cache  in  the  created  AtFS  object
       repository.  You  may set the maximum total number (cT) of derived files to be stored, the maximum number
       of derived files per name (cN) and the maximum number of derived files with the same name  and  the  same
       caching  attribute  (cA).  The  relationship  of the three values must always be cT >= cN >= cA. For more
       information on that topic check the cacheadm(1) manual page. The -cQ option queries the  actual  settings
       for the derived object cache size.

OPTIONS

       -cA max_cached_per_cacheattr
               Set  the  maximum number of derived files with the same name and the same caching attribute to be
               stored. Default is 1.

       -cN max_cached_per_name
               Set the maximum number of derived files with the same name to be stored. Default is 3.

       -cT max_total_cached
               Set the total maximum number of derived files to be stored in the derived object  cache.  Default
               is 64.  -g group Set the group id of the generated directory to group (see chgrp(1)).  -h Display
               help message.

       -l path
               Create  an AtFS directory entry by setting a symbolic link to an existing AtFS object repository,
               rather than creating a new (empty) one.  On System V  machines,  a  file  containing  the  target
               directory  name  will  be  generated.  The  AtFS functions will interpret this as surrogate for a
               symbolic link.

       -m mode
               Set the mode of all generated directories to mode (see chmod(1)).

       -v      Output version identification string.
