Assigning an Initial Working Directory
°
A user group can continue to exist after its last user has been removed from it.
•
There can be up to 65,535 user groups, including 256 administrative groups.
•
There is no limit on the number of file-sharing members (users) in a user group. An
administrative group can have up to 256 users for user management and
administration purposes; an administrative group can have additional file-sharing
members administered through a different administrative group.
•
User groups with group numbers above 255 are file-sharing user groups rather
than administrative user groups.
In the OSS environment, users can have the following additional attributes (which are
ignored in the Guardian environment):
•
Initial working directory (if none is defined, the default value is null). Some servers
do not use this attribute value; instead, they provide alternative attributes.
•
Initial program (if none is defined, the default value is null). Some servers do not
use this attribute value; instead, they provide alternative attributes.
For detailed information about user groups, user definitions, aliases, the Safeguard
subsystem, and SAFECOM, see the Safeguard Administrator’s Manual and the
Safeguard Reference Manual. For detailed information about the equivalent concepts
and facilities in a third-party product, see the appropriate manual.
Assigning an Initial Working Directory
An initial working directory is the location in the OSS file system where a user is placed
upon entry to the OSS environment. An initial working directory is also known as a
home directory.
If you log in, remain in the same directory, and refer to a file without specifically
identifying any directory, Open System Services assumes that the file belongs to the
initial working directory. This concept is similar to the concept of the default volume and
subvolume in the Guardian environment.
You should provide each OSS user with an initial working directory in the OSS file
system. The initial working directory can be assigned in several ways:
•
You can use the Safeguard subsystem.
•
For Telserv indirect users only, you can use a TACLCSTM file.
HP recommends that you use the Safeguard subsystem and its INITIAL-DIRECTORY
attribute.
If you do not provide an initial working directory for a user, the effective default initial
working directory for the user depends on how the user gained access to the OSS
environment. For example, assume that a user logs in through a TACL prompt and
uses the OSH command when the Safeguard null default value is in effect for the initial
working directory. If OSH cannot find any other definition of an initial working directory,
it uses /G/volume/subvolume as the user’s effective initial working directory, where
