You might have an environment that can function with even less information
than that shown in the example. For example, to disable the operator log file,
use REPLY/NOLOG, or to disable accounting, use SET ACCOUNTING/DISABLE.
For more information about using these commands, refer to the OpenVMS DCL
Dictionary.
H.5.5 Accessing Example and Documentation Files
If you have network access to another OpenVMS system (especially a timesharing
system), you do not need to duplicate the example files distributed in the
OpenVMS VAX or DECwindows Motif for OpenVMS VAX kits if they are available
on the remote system. Similarly, remote access to the online documentation files
also saves considerable disk space on any system with constrained disk space.
H.6 Managing Multiple Disk Systems
The following sections describe techniques for managing multiple disk systems.
In addition to the goal of reducing the space requirements on the system device,
it is possible to simultaneously reduce some of the I/O load to the system disk by
redirecting necessary functions to an alternate device.
H.6.1 Alternate Page and Swap Files
Setting up alternate page and swap files is one of the best ways to reduce
both the system disk space usage and I/O overhead. If you set up only a small
primary page file on the system disk and install additional page and swap files
in the startup command file SYS$MANAGER:SYPAGSWPFILES.COM, you can
permanently cause these files to consume the least amount of space on the system
device. For more information about setting up alternate page and swap files,
refer to the OpenVMS System Manager’s Manual.
