The Question is: We are COMPAQ Alliance Partner and, we want to distribute our Software Products on CD-ROM? What CD-ROM Formats can we use (ISO-9660 Level ?)?; and I understand we might need some special Software for OpenVMS to read the software (especially on a VAX). Please Advise Thanks The Answer is :
The OpenVMS Wizard would STRONGLY recommend using your CSA contact(s)
for assistance with this question and with the various related product
distribution questions that invariably ensue.
OpenVMS V6 and later can read ISO 9660 format CD-ROMs, and an ISO-capable
add-on kit is (was) available for OpenVMS VAX V5.5-2 systems.
OpenVMS does not support various extensions, such as Rock Ridge.
Packages permitting the creation of dual-format CD-ROMs -- ISO 9660 and
ODS-2 on the same media -- are also available from various vendors (or
as freeware/shareware). This -- or the use of a native-format ODS-2 or
ODS-5 CD-ROM disk -- is the prefered solution.
PCSI installation from ISO 9660 can involve several extra steps -- such
as a specific MOUNT command, or the relocation of the PCSI installation
kits, or the unzip of the PCSI sequential kit onto an OpenVMS disk for
later installation. (These steps are not required with PCSI software
installations from native ODS-2 or ODS-5 CD-ROM media.)
An example of an ISO-9660 MOUNT command follows:
MOUNT/MEDIA=CD/UNDEFINED_FAT=(FIXED:NONE:8192)/OVERRIDE=ID <disk>
There are known problems with attempts to use PCSI to install PCSI
kits located on ISO-9660 CD-ROM media on OpenVMS versions including
V7.2. These problems are known to presently prevent PCSI installations
from ISO-9660 media.
Information on creating CD-R media on OpenVMS is included in the OpenVMS
FAQ. (ODS-2 and ODS-5 media can also be created on CD-R drives on most
other systems that are capable of block-oriented media creation.)
