Perl for OpenVMS November
2005 Perl
Version 5.8-6 for OpenVMS Alpha (based on Perl Version 5.8.6) Perl
Version 5.8-6 for OpenVMS I64 (based on Perl Version 5.8.6) Contents
What's New Two
new kits for Perl for OpenVMS V5.8-6 are now available - one for OpenVMS I64
Version 8.2 and higher, and one for OpenVMS Alpha 7.3-2 and higher. Perl for OpenVMS V5.8-6 is intended to work with the Secure Web Server Version 2.1 and higher only. (Use Perl Version 5.6-1 ECO 3 with the Secure Web Server Version 2.0. Use Perl Version 5.6-1 with the Secure Web Server Version 1.3-1.) Perl
for OpenVMS V5.8-6 is based on Perl 5.8.6. See http://dev.perl.org/perl5/news/2004/perl-5.8.6.html
for more information. OpenVMS
Alpha Version 7.3-2 or higher Perl
runs with the Secure Web Server for OpenVMS via CSWS_PERL. You can also use
Perl in a standalone mode through the command line. You do
not need to install the Secure Web Server for OpenVMS nor CSWS_PERL to use Perl
for OpenVMS. For
more information about Perl, see The Source for Perl at http://www.perl.com/
and Perl Mongers
at http://www.perl.org/. For
a list of what has changed in the latest kit, see the PERL586.RELEASE_NOTES
file in the Perl for OpenVMS kit. To view the file before you install the Perl
kit, enter the following command: $ PRODUCT EXTRACT RELEASE_NOTES PERL See
the CSWS_PERL for HP Secure Web Server for OpenVMS Installation
Guide and Release Notes for information about running CSWS_PERL
with Perl and the Secure Web Server for OpenVMS. Perl
packages sometimes contain documentation information within the package. If the
installed package includes documentation, you can view it by defining the
following foreign command: $ PERLDOC :== $PERL_ROOT:[000000]PERL.EXE - PERL_ROOT:[LIB.POD]PERLDOC.COM
-t For
PERLDOC help, enter the following command: $ PERLDOC -h » Download
Perl Version 5.8-6 for OpenVMS Alpha Also available
for download are earlier versions of Perl for OpenVMS: » Download Perl V5.6.1 for OpenVMS Alpha For Alpha Only: Apply the Perl 5.6.1 ECO 3 kit (CPQ-AXPVMS-PERL561_UPDATE-V0300--4.PCSI-DCX-AXPEXE) if you want to use Perl
5.6.1 with the Secure Web Server Version 2.0 and CSWS_PERL Version 2.0 on
OpenVMS Alpha. (See
the PERL for OpenVMS Alpha
Installation Guide and Release Notes to download PERL for OpenVMS Alpha Version
5.6.1 ECO 3.) To
expand the Perl for OpenVMS self-extracting file, enter one of the following
commands, depending on the kit you download: $ RUN CPQ-AXPVMS-PERL-V0508-6-1.PCSI_SFX_AXPEXE ! for Alpha $ RUN
HP-I64VMS-PERL-V0508-6-1.PCSI_SFX_I64EXE ! for I64 The
system expands the file and names the decompressed file CPQ-AXPVMS-PERL-V0508-6-1.PCSI
or HP-I64VMS-PERL-V0508-6-1.PCSI. Do not rename this
file. Upgrading Perl from an
Earlier Version You
can install a new Perl for OpenVMS kit over an existing version of Perl.
Restart the Secure Web Server for the new Perl kit to take effect. Important If
you install a new Perl kit to a different location from an earlier Perl kit
using the /DESTINATION qualifier on the PRODUCT INSTALL command line, the new
Perl kit will not work with the Secure Web Server unless you follow the steps
below. This occurs because the CSWS_PERL for Secure Web Server kit (also known
as mod_perl) adds extensions to Perl. Those extensions, and any user-added
extensions, remain in the original location. If
you want to install a new Perl kit to a different location, follow these steps:
1.
Save your CSWS_PERL configuration file
(APACHE$COMMON:[CONF]MOD_PERL.CONF). 2.
Make sure the PERL_ROOT logical name is pointing to the old
Perl location. 3.
Remove CSWS_PERL. 4.
Install the new Perl kit to the new location. 5.
Point the PERL_ROOT logical name to the new Perl location. 6.
Re-install CSWS_PERL. 7.
Re-install any user-installed Perl extensions. 8.
Restore your CSWS_PERL configuration file. To
install the Perl for OpenVMS kit, enter the following command. $ PRODUCT INSTALL PERL Note: Perl is not dependent on the Secure Web Server for OpenVMS installation
and can reside anywhere on the system. The Secure Web Server uses the PERL_ROOT
logical to locate Perl. As
the installation procedure progresses, the system displays information similar
to the following: $ PRODUCT INSTALL PERL/DEST=DISK$DKA0:[000000] The following product has been selected: CPQ AXPVMS PERL V5.8.6 Layered Product Do you want to continue? [YES] Configuration phase starting ... You will be asked to choose options,
if any, for each selected product CPQ AXPVMS PERL V5.8.6 Hewlett Packard Company. * This product does not have any configuration
options. Execution phase starting ... The following product will be installed to destination:CPQ AXPVMS PERL V5.8.6 DKB100:[000000.] Portion done: 0%..10%..20%..30%..40%..50%..60%..70%..80%..90%..100% The following product has been installed:CPQ AXPVMS PERL V5.8.6 Layered Product CPQ AXPVMS PERL V5.8.6 Post-installation tasks are required. If you are running the Secure Web Server
(CSWS) with Perl support, you must stop and restart the Apache server
software to complete the installation: $ @SYS$STARTUP:APACHE$SHUTDOWN $ @SYS$STARTUP:APACHE$STARTUP 1.
Define the PERL_ROOT logical In order for the Secure
Web Server for OpenVMS software to use Perl (via CSWS_PERL), Perl must be made
available to the server processes. Two logicals are required for the Secure Web Server
to locate this kit. If no other versions of Perl are being used on this
system, it is recommended that these logicals be defined systemwide. Otherwise,
the logicals must be defined as either /GROUP or /JOB by the main server
process. The PERL_ROOT logical
locates the top level directory of the Perl installation. It is rooted and must
be a concealed logical. For example: $ DEFINE/SYSTEM/EXEC/TRANSLATION=CONCEALED - _$ PERL_ROOT DKB100:[PERL5_8_6.] 2.
Define the PERLSHR logical Once the top level
directory is defined, the Secure Web Server for OpenVMS requires access to the
shareable image in this kit (PERLSHR.EXE). By default, OpenVMS looks in
SYS$SHARE, but since this kit can be installed anywhere, this logical is
necessary. For example: $ DEFINE/SYSTEM/EXEC PERLSHR - _$ PERL_ROOT:[000000]PERLSHR.EXE The Secure Web Server is
now able to locate this installation of Perl. 3.
Define the foreign command Perl can also be used in
a standalone mode without the Secure Web Server. To use Perl in this manner,
define a foreign command to the Perl main image. For example: $ PERL :== $PERL_ROOT:[000000]PERL.EXE Perl scripts can then be
executed from the command line by using this verb and the Perl script name as
the parameter. Use the command "Perl -h" to see other options. You can remove the Perl
for OpenVMS kit by using the POLYCENTER Software Installation utility. To do
so, enter the following command: $ PRODUCT REMOVE PERL This command removes all
files and directories created by this installation. Note that if you install Perl
packages to extend the capabilities of Perl or create additional files in the
installation area, PCSI will not have knowledge of these files and will not delete them. This will
cause the directory structure to remain because the directories will not be
completely empty. Some manual intervention may be needed to completely remove
the kit. This section contains
notes on the current release of Perl for OpenVMS. ·
Extended filename support not included This version of Perl for OpenVMS
does not include support for extended filenames. Use of extended filenames in mod_perl
directives or within Perl scripts may cause unpredictable results. HP recommends that
you convert any special characters within file and directory names to a
suitable ODS-2 supportable character, such as the underscore ("_") character.
·
Tracking versions of Perl and CSWS_PERL The CSWS_PERL and Perl
kits are tightly connected. Future versions of Perl or CSWS_PERL may not
interact correctly across version numbers. ·
Perl for OpenVMS Version 5.8-6 works with CSWS_PERL Version 2.1.
·
Perl for OpenVMS Version 5.6.1 ECO3 works with CSWS_PERL Version
2.0. ·
Perl for OpenVMS Version 5.6.1 works with CSWS_PERL Version 1.1. ·
Perl Version 5.5-3A3 works with CSWS_PERL Versions 1.0-1 and 1.0. ·
Multiple versions of Perl You can run this Perl
kit on the same system with other versions of Perl. If you choose to do this,
be careful that the Secure Web Server software "sees" this version of
Perl. Otherwise, your web based scripts will not operate correctly. The way the
Secure Web Server sees Perl is through logical names. See Post-Installation
Tasks for information about how to set these logical names. ·
Perl example syntax Some examples found in
Perl manuals do not show the same syntax as that required by this version of
Perl. HP recommends that you use the PERLDOC feature to display the help text (if
available) to find the correct syntax. ·
Perl-status location Through the Secure Web
Server, the "perl-status" location gives useful information about
Perl and CSWS_PERL. Part of that information requires the Devel::Symdump Perl
package to be installed. The Perl for OpenVMS kit does not contain that
package. However, it can be obtained from CPAN via the web at http://www.perl.com.
