Customizing the Operating System
5.1 Adding and Deleting Optional Files
Depending on the system you are using, you can add or delete files in one of the
following ways:
• On VAX systems, you can use the OpenVMS Tailoring utilities, VMSTAILOR
and DECW$TAILOR:
VMSTAILOR—applies to optional system files
DECW$TAILOR—applies to support for DECwindows
Delete files from and add files to the system disk by identifying classes and
subclasses of operating system files that you want to add or delete. You might
delete or add an entire class or selected subclasses of files within a class.
If you delete files, you can add them again at any time using VMSTAILOR or
DECW$TAILOR and your operating system distribution media.
Refer to the Upgrade and Installation Manual for more information about
VMSTAILOR and DECW$TAILOR.
• On Alpha systems, you can use the POLYCENTER Software Installation
utility to add or delete optional system files. Add or delete files by selecting
or deselecting options and suboptions.
To invoke the POLYCENTER Software Installation utility for this purpose,
you can use either of the following methods:
Use the DCL command PRODUCT RECONFIGURE.
Use the DECwindows Motif interface from the POLYCENTER Software
Installation utility and select the Reconfigure option on the Mode menu.
For more information about using the POLYCENTER Software Installation
utility, see Section 3.7.
5.2 Modifying Site-Specific Startup Command Procedures
An important part of customizing your system is to create or modify site-specific
startup command procedures. Adding commands to these procedures ensures
that the commands are executed each time the system reboots.
5.2.1 Understanding Site-Specific Startup Command Procedures
You should understand the following terms:
Term Definition
Startup command procedure A command procedure that executes when the system
starts up.
Site-independent startup
command procedure
A startup command procedure that is required for and
provided with all OpenVMS systems, regardless of
site-specific requirements. This procedure is named
SYS$SYSTEM:STARTUP.COM. Do not modify this
procedure.
When your system boots, it automatically executes
STARTUP.COM. For more information, see
Section 4.1.4.
