Tools for special tasks Compression of the ACL Database

Product Manual U7613-J-Z815-6-76

The AS/X acladm utility with its different optio ns 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 mou nted)

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 usi ng

several tools from Advanced Server for UNIX. During the reorganization process the s erver

has to be stopped, therefore you should use a maintenance date for compressio n.

Depending on the size of the database the compression may take some time.

ÊCheck 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.

ÊStop the server

net stop server

Al l active connections with clients will be closed.

ÊSave the actual ACL database

e.g. cp /var/opt/lanman/datafiles/acl* /save/datafiles

Take care that there is enough space in /save.

ÊClean 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 n eed. 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.

ÊCheck 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.

ÊIf necessary repair it:
