The AS/X acladm utility with its different options removes entries identified as super-
fluous in the configuration when the command is called. You must therefore make
sure that the system configuration is complete (i.e. all file systems are mounted)
and that the AS/X configuration is up to date. For example, if you change the AS/X
MixedCaseSupport registry parameter to a different value than that at Advanced
Server runtime, it may happen, for example, that
acladm -P will delete too many ACL
entries.
The following description shows how an the ACL database can be reorganized using
several tools from Advanced Server for UNIX. During the reorganization process the server
has to be stopped, therefore you should use a maintenance date for compression.
Depending on the size of the database the compression may take some time.
Ê Check available disk space
In the file system where /var/opt/lanman is located the free space should be at least the
size of the ACL database.
Ê Stop the server
net stop server
All active connections with clients will be closed.
Ê Save the actual ACL database
e.g. cp /var/opt/lanman/datafiles/acl* /save/datafiles
Take care that there is enough space in /save .
Ê Clean old ACL database
Cleaning of the database takes place in two steps: In the first step you have to check
the data for correctness and you have to repair them in case of need. Then you can
remove all entries which are no longer necessary, e.g. entries of files and directories
which are no longer existing in UNIX.
Ê Check the /var/opt/lanman/datafiles/acl database:
/var/opt/lanman/bin/acladm -C -n
The -n option, when used with the -P or -C options, will give a complete list of all entries
that need to be deleted or fixed. No changes are made to the ACL store.
Ê If necessary repair it:
