H.3 Installing OpenVMS VAX and DECwindows Motif for OpenVMS
VAX
In general, installing OpenVMS VAX Version 7.3 and the latest version of
DECwindows Motif for OpenVMS VAX is easier than doing an upgrade because
there are no user files on the disk when you perform the installation. However,
because the total size of the two kits is larger than the capacity of the RZ24 disk,
you cannot select some options and you might have to do some tailoring.
H.3.1 Installing OpenVMS VAX Version 7.3
By itself, the entire OpenVMS VAX Version 7.3 distribution kit fits on the RZ24
system disk. So, the easiest approach might be to select both the library and
optional save sets, then use the VMSTAILOR and DECW$TAILOR utilities to
increase the free space before installing the DECwindows Motif for OpenVMS
VAX layered product.
If you plan to run DECnet for OpenVMS, be sure to select the library save set. If
you do not perform system programming or BLISS programming, do not have an
LPA11 device, do not need any of the OpenVMS example files, and do not need
the UETP facility, you can choose not to select the optional save set during the
installation. The BLISS support in the optional save set (approximately 7000
blocks) and the examples (over 8500 blocks) are two of the largest single areas
that you can easily tailor off.
You might choose not to install the Help Message (MSGHLP) database because
this option is also very large (about 10,000 blocks). Or, you can select it at
the expense of other tailorable options later (or at the expense of reduced user
capacity). Or you can install the Help Message database and then customize it
to remove messages for facilities that you do not use. (Refer to the OpenVMS
System Manager’s Manual, Volume 1: Essentials for details about how to do this.)
Once the OpenVMS VAX installation is complete, set up the dump file as
required. It is preferable not to have a dump file at all or to use the paging file
as described in Section H.5.1. Also, set fixed sizes for the page and dump files so
that AUTOGEN does not continually resize them as you proceed with tailoring
and installing the DECwindows Motif for OpenVMS VAX layered product. When
your environment is complete, you can remove the fixed sizes to allow AUTOGEN
to calculate appropriate sizes based on the final space on the disk.
To fit the operating system on an RZ24 disk and have sufficient space to add some
layered product or application packages and have user space remaining, you can
generally support, at most, one programming language and no online examples or
manuals. Use the VMSTAILOR and DECW$TAILOR utilities to remove software
you do not need.
H.3.2 Installing DECwindows Motif for OpenVMS VAX
Depending on the options and setup of your system, you might have sufficient
space to install the entire DECwindows Motif for OpenVMS VAX kit. However, it
is likely that you again will need to remove support for all but one programming
language and not include the examples. Because the programming support save
sets for each language are large, choose only the support for languages you really
need. In the case of the example files, you might want to install them if you
have the space required, and then tailor them off once you have perused them or
copied them to another area.
