4.8 Adding and Removing Operating System Files

To remove OpenVMS VAX operating system ﬁles from the system disk, use

VMSTAILOR or DECW$TAILOR. For example, if you are not running DECnet

software, use VMSTAILOR to remove the ﬁles associated with DECnet.

Note

You cannot use VMSTAILOR to remove ﬁles installed on an alternate

device from save set VMS073.E.

For complete information about using VMSTAILOR and DECW$TAILOR to

remove optional OpenVMS VAX software, see Chapter 10.

4.9 Installing Layered Products

Back up your system disk and then use either the VMSINSTAL command

procedure or the POLYCENTER Software Installation utility to install layered

products on your system.

For additional information about installing layered products, refer to the

OpenVMS System Manager’s Manual.

4.10 Backing Up the Customized System Disk

After you have customized the OpenVMS VAX operating system to your

satisfaction and installed your layered products, protect your work by making a

standalone backup copy of the system disk.

For complete information about backup operations, refer to the upgrade and

installation supplement for your VAX computer and the system manager’s

4.11 Running AUTOGEN

the AUTOGEN.COM procedure to set the values of system parameters and the

sizes of the page and swap ﬁles according to the system’s workload.

feedback information from the running system. As a postinstallation task, you

should run the AUTOGEN.COM procedure again to properly tune the system.

Run AUTOGEN as follows:

1. After 24 hours of operation, run AUTOGEN in feedback mode and reboot the

system.

2. Run AUTOGEN again in feedback mode two workdays later, and reboot the

system.
