8.16 Installing Layered Products
8.16 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. If the system contained Compaq TCP/IP Services for
OpenVMS previous to the upgrade, you must reinstall it now.
For additional information about installing layered products, see the OpenVMS
System Manager’s Manual.
8.17 Backing Up the System Disk
Compaq recommends that you protect your work by performing the following
operations:
• Use SYS$UPDATE:CONSCOPY.COM to back up the console media (if
applicable).
• Make a standalone BACKUP kit on removable media and on the system disk.
If your console media is a TU58 tape cartridge or an RX01 diskette, use the
standalone BACKUP copy you made before you began the upgrade. (See
Section 5.4.2.)
• Back up the system disk.
For complete information about these operations, refer to the upgrade and
installation supplement for your VAX computer.
8.18 Running AUTOGEN
When you upgraded the OpenVMS VAX operating system, the procedure executed
AUTOGEN to set the values of system parameters and the sizes of the page and
swap files according to the system’s workload.
In many cases, AUTOGEN can improve system performance by using dynamic
feedback information from the running system. As a postinstallation task, you
should run AUTOGEN again using the feedback mechanism to make further
adjustments to system parameters.
When AUTOGEN runs after an upgrade, it uses the parameter values
in SYS$SYSTEM:MODPARAMS.DAT. Note that hardcoded values in
MODPARAMS.DAT affect AUTOGEN’s calculations of the feedback parameters.
For AUTOGEN to properly calculate minimum values, you should replace the
hardcoded values in MODPARAMS.DAT with MIN_ values. The MIN_ prefix
specifies the minimum value to which a parameter can be set by AUTOGEN.
If you are not satisfied with the parameter settings calculated by AUTOGEN,
you can modify the parameter values by editing MODPARAMS.DAT as explained
in the OpenVMS System Manager’s Manual, Volume 2: Tuning, Monitoring, and
Complex Systems.
After you have upgraded the operating system, run AUTOGEN again using the
following procedure:
1. After 24 hours of operation, run AUTOGEN in feedback mode and reboot the
system.
