H-Sphere requires the following Perl modules on all its servers:DBI
LWP-ParallelUA (libwww in FreeBSD)
DBD-MySQL (MySQL-modules in FreeBSD)
The above modules are assembled into a ready install packages and are available for public download.
We strongly recommend you NOT to upgrade the modules listed above as they proved to provide the most optimal performance. However, if you decide to upgrade modules, please follow this upgrading procedure at your own risk:
- Download the file from www.cpan.org
- untargzip the archive
- cd into directory
Compile and install the package:
During the upgrade, it may turn out that additional packages are required. You need to set up these packages and try the installation again. If you don't know where to get these packages, try cpan.org
Alternatively, you can update perl modules using the perl CPAN.pm module.
DO NOT try to upgrade H-Sphere Perl core in any case, since it will affect H-Sphere system performance. Restoring the system by our technicians is a subject to extra support charges.
