Using TACL to Manage Remote Files
Using TACL to Manage Remote Files
One of the major features of the Expand subsystem is network transparency. Because
access to the network is transparent to the user, the Expand subsystem does not
include its own network commands. This subsection describes how to use TACL
commands to manage remote files.
Using Disk-File Names
A disk file has a unique file name consisting of four parts, with each part separated by
a period. An example of a disk file name is
\WEST.$DISK1.SUBVOL2.FILENAME
•
The node name (\WEST) is the name of the node (system) where the file resides.
All nodes must be named. A node name always begins with a backslash (\) and is
limited to eight characters including the backslash. You can omit the node name if
the file resides on the current default node.
•
The volume name ($DISK1) is the name of the disk volume where the file resides.
The volume name must begin with a dollar sign ($), followed by one to seven
alphanumeric characters. The character following the dollar sign must be a letter.
•
The subvolume name (SUBVOL2) is the name of a set of files in the same disk
volume. The subvolume name can contain from one to eight alphanumeric
characters and must begin with a letter.
•
The file identifier (FILENAME) is the name of an individual file. The file name can
contain from one to eight alphanumeric characters and must begin with a letter.
A fully qualified file name has four parts: node name, volume name, subvolume
name, and file identifier. A partially qualified file name omits one or more of the parts.
The following are examples of partially qualified file names:
The following is an example of a fully qualified file name for a file that resides on the
node named \MEL:
\MEL.$GERT.FERN.HERST
You must use a fully qualified file name when accessing a file on a remote node in your
network.
Note. Selected TACL commands are described in this subsection. For the syntax and refer-
ence information about all TACL commands and programs, refer to the TACL Reference Man-
ual.
