CSWS_PERL Version 2.1 is intended to work with the Secure Web Server Version 2.1 and higher only. (Use CSWS_PERL Version 2.0 and Perl Version 5.6-1 ECO 3 with the Secure Web Server Version 2.0. Use CSWS_PERL Version 1.1-1 and Version Perl 5.6-1 with the Secure Web Server Version 1.3-1.)

CSWS_PERL Version 2.1 is based on mod_perl 2.0.0-RC4 (identified as 1.999.21 by /server-info). See http://perl.apache.org/ for more information.

Expanding the Kit

To expand the CSWS_PERL for OpenVMS self-extracting file enter one of the following commands, depending on the kit you download:

$ RUN HP-I64VMS-CSWS_PERL-V0201--1.PCSI_SFX_I64EXE ! for I64

The system expands the file and names the decompressed file CPQ-AXPVMS-CSWS_PERL-V0201--1.PCSI
or HP-I64VMS-CSWS_PERL-V0201--1.PCSI. Do not rename this file.

Before You Begin the Installation

Before you begin the installation of CSWS_PERL, do the following:

         Add logical definitions for Perl

You must define the logical PERL_ROOT before you install or remove the CSWS_PERL kit. The CSWS_PERL kit installs several files that extend the capabilities of Perl. The PERL_ROOT logical must be available to CSWS_PERL in order to add and remove those files.

If you are running multiple versions of Perl, make sure that the Secure Web Server can only see the version of Perl that has been modified to work with the Secure Web Server. You can do this by adding the logical definitions to LOGIN.COM for the account running the Secure Web Server. Note that if the logicals are defined this way, they must be JOB logicals so that they can be passed to any subprocesses.

To define PERL_ROOT and PERLSHR, enter the following commands:


Installing CSWS_PERL for OpenVMS

To install the CSWS_PERL for the Secure Web Server for OpenVMS kit, enter the following command.

Note: You must install the CSWS_PERL kit into the same device and directory where you installed the Secure Web Server for OpenVMS.

For example:


For a description of the features you can request with the PRODUCT INSTALL command when starting an installation such as running the IVP, purging files, and configuring the installation, see the POLYCENTER Software Installation Utility User's Guide.

As the installation procedure progresses, the system displays information similar to the following:

 The following product has been selected:

 Post-installation tasks are required for MOD_PERL for OpenVMS.
 The release notes give detailed directions. This information
 is a brief checklist.
 This installation modifies APACHE$ROOT:[CONF]HTTPD.CONF to
enable MOD_PERL. Check HTTPD.CONF for accuracy. The line
"Include /apache$root/conf/mod_perl.conf" should be the only
 difference. Also study the MOD_PERL configuration file
for options required for your
The APACHE::Registry module is enabled by default and
 the location "/perl" is defined to access it.
 The Apache server must be shutdown and restarted to make these
 changes to the HTTPD.CONF file take place. 
Test that MOD_PERL
 is working by accessing the sample script from a browser:
 Thank you for using the Secure Web Server for OpenVMS.

Post-Installation Task

         Review MOD_PERL.CONF

Review the APACHE$COMMON:[CONF]MOD_PERL.CONF configuration file to be sure it enables all of the features required for your site.

Removing CSWS_PERL for the Secure Web Server for OpenVMS

You can remove the CSWS_PERL kit by using the PRODUCT REMOVE command. The Secure Web Server must be shut down before you remove CSWS_PERL.

To remove CSWS_PERL, enter the following commands:


The PRODUCT REMOVE command removes all files created by this installation. It also attempts to remove the directories defined by this installation. The removal also deletes the reference to the MOD_PERL.CONF configuration file from the HTTPD.CONF file.

Release Notes

This section contains notes on the current release of CSWS_PERL.

         Extended filename support not included

This version of CSWS_PERL 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.

         Order of installing optional modules

Previous CSWS_PERL kits required that you install CSWS_PERL before installing other optional kits, if you were installing the kits on the same system. This restriction has been removed. You can install CSWS_PERL before or after CSWS_PHP and CSWS_JAVA, or you can install one without the others.

However, you must install and configure the Secure Web Server for OpenVMS and Perl for OpenVMS before you install CSWS_PERL.

         File protections of Perl scripts

When you create a Perl script, make sure it is world readable and world executable.

For example:


         Tracking versions of CSWS_PERL and Perl

The CSWS_PERL and Perl kits are tightly connected. Future versions of Perl or CSWS_PERL may not interact correctly across version numbers. This release of CSWS_PERL works with Perl V5.8.6.

         Shareable image mismatch

If you are pointing at the wrong version of Perl, an ident mismatch occurs and the following error appears in the log file.

Syntax error on line 207 of /apache$root/conf/httpd.conf:
Can't locate API module structure `perl_module' in file
%LIB-E-ACTIMAGE, error activating image !AS
