Informs the system to close the specified volume set and take
it offline. (Native Mode)
Operation Notes |
 |
This command notifies the system to close the volume set and
take it offline. This is done when all users have ceased using files
on the volume set, and when any program file that has been allocated
on the volume set has been deallocated (via the DEALLOCATE
command). Once the VSCLOSE
command is issued for a volume set, individual users can no longer
issue VSRESERVE
or MOUNT commands
for the volume set.
Specifying the NOW
parameter permits the operator to take the volume set offline immediately,
unless a VSRESERVESYS
or an LMOUNT
command has been issued, or unless a program file has been allocated
on the volume set.
This command restricts access to the volume set. Jobs or sessions
are granted access to the volume set only if they have at least
one open file on the volume set or if they have already issued an
explicit VSRESERVE
or a MOUNT command
for the volume set.
The MPE/iX naming convention for volume sets differs from
that of MPE V/E for private volumes.
In MPE V/E, the name A.B.C indicates that B is the name of
a group and that C is the name of an account. MPE/iX accepts that
name, but no interpretation is made as to the referencing of B and
C. Instead, MPE/iX treats A.B.C as a single, long string name. It
is the flexibility of the MPE/iX naming convention that makes it
possible for MPE/iX to work with a volume set designated A.B.C.
MPE/iX volume set names may consist of any combination of
alphanumeric characters, including the underbar (_)
and the period (.).
The name must begin with an alphabetic character and must consist
of no more than 32 characters.
A volume set called MY_OWN_PERSONAL_VOLUME_SET
is acceptable in MPE/iX, and so is MY.OWN.PERSONAL.VOLUME.SET;
similarly, A.B.C is acceptable. If a volume set is named according
to the MPE V/E naming convention (A.B.C), you must use an unambiguous
reference when using the MPE/iX volume set commands, such as:
Entering
Vcommand A fails
to access the volume set. You cannot specify the first part of the
volume set name alone and expect the group and account to default.
Use |
|
This command may be issued from a session, job, program, or
in BREAK. Pressing Break has
no effect on this command. This command may be issued only from
the system console unless distributed to other users with the ALLOW
command.
Examples |
|
To close the volume set ACCOUNTING_PAYROLL,
enter:
VSCLOSE ACCOUNTING_PAYROLL |
However,
if a VSRESERVESYS
command has been issued for ACCOUNTING_PAYROLL,
then a message is displayed on the console. In order to close this
volume set and take it offline, the operator has to issue these
commands:
VSRELEASESYS ACCOUNTING_PAYROLL
VSCLOSE ACCOUNTING_PAYROLL |
