Customizing the Operating System
5.2 Modifying Site-Specific Startup Command Procedures
that operator-assisted mounts are disabled. To enable this feature during
SYSTARTUP_VMS.COM, specify /ASSIST with each MOUNT command.
For a DSA disk, you must also insert a WAIT statement in the command
procedure prior to the first MOUNT statement. The wait time is
controller-dependent. If you omit a WAIT statement, the MOUNT request
might fail with a ‘‘no such device’’ status. Refer to the OpenVMS I/O
User’s Reference Manual for more information.
For more information about public volumes, see Section 9.1.4 and Section 9.5.
For more information about the MOUNT command, refer to the MOUNT section
of the OpenVMS System Management Utilities Reference Manual.
5.2.7.2 Mounting Disks That Must Be Available Early in Startup
If you have any disks that must be mounted early in startup, you can add
MOUNT commands to SYCONFIG.COM. For example, your site might require
that certain files be available before SYSTARTUP_VMS.COM executes. For more
information about SYCONFIG.COM, see Section 5.2.4.
5.2.7.3 Setting Terminal and Printer Characteristics
To establish the device characteristics of the terminals and printers on the
system, use a series of SET commands in your startup command procedure. For
more information about the commands you use to set up devices, see Section 8.6.1
and Section 8.8.1.
If your configuration is simple, you can add the commands to SYSTARTUP_
VMS.COM. If your configuration requires a large number of commands, create a
separate command procedure (for example, DEVICE_SETUP.COM) and execute
it from SYSTARTUP_VMS.COM. When the device setup command procedure
finishes executing, control returns to SYSTARTUP_VMS.COM.
5.2.7.4 Starting Queues and Enabling Autostart for Queues
You should add commands to SYSTARTUP_VMS.COM to perform the following
tasks:
• Enable autostart for queues
• Start nonautostart execution queues
If your configuration is simple, you can add these commands to SYSTARTUP_
VMS.COM. On systems with a large number of queues, you might want to include
the commands in a separate file named, for example, STARTQ.COM, and include
a command in SYSTARTUP_VMS.COM to invoke the queue startup command
procedure. The autostart feature simplifies queue startup, and allows you to
start queues with fewer commands. Compaq recommends you use autostart
queues whenever possible to simplify queue startup. For more information about
autostart queues, see Section 14.1.3.
For more information about starting queues and enabling autostart for queues in
system startup, see Section 14.4.1.
