finally it works! ;-)

the problem was, that i needed to install the Apache::DBI package from cpan... since then the following configuration in apache2-perl-startup.pl works perfectly:

use Apache::DBI ();

Apache::DBI->connect_on_init('DBI:mysql:otrs', 'otrs', 'password');

use DBI ();

use DBD::mysql ();

thanks a lot for your precious help!

regards,

patrick.

ps: so i don’t need debian... thanks anyway... ;-)

Yes. This work for me with the following lines:

Apache::DBI->connect_on_init('DBI:mysql:otrs', 'otrs', 'password');
use DBI ();

use DBD::mysql ();

If you wish to rebuild your entire server using Debian, I can provide you a step-by-step document... ;-)

doesn’t change anything... i always get an error like this:

“Can’t locate Apache2/DBI.pm in @INC (...)” or "Can't locate Apache/DBI.pm in @INC (...)"

does this work for you?

Uhm... maybe you should user Apache::DBI instead of Apache2::DBI?

ok, finally i could load the mod_perl into the apache configuration... so this seems to work fine now...

but i have still the issue that, when i include the following to line into the apache2-perl-startup.pl:

use Apache2::DBI ();

Apache2::DBI->connect_on_init(‘DBI:mysql:db’,’user’,’pw’); [of course this are just examples]

i get this error in the error_log file of the apache:

Can’t load Perl module Apache2::DBI for server MYSERVER, exiting

when i comment the two lines in question and use instead:

use DBI ();

use DBD::mysql ();

everything works perfect!

any idea?

thanks.

patrick.

daniele,

thanks a lot for your reply.

unfortunately i can’t solve this mod_perl issue. i already had all this packages (apache2, apache2-perl-mod and apache-dbi-perl) installed... and when i had a look on the otrs.conf file i recognized that everything was exactly the same like the one you posted in... except this line:

PerlModule Apache::DBI

but as far as i put this line into this configuration file, i get an error when i try to start my apache:

“Invalid command ‘PerlModule’, perhaps misspelled or defined by a module not included in the server configuration”

well, i checked the spelling and everything was fine. i think the problem is that first of all the module has to be included in the apache configuration... but i am not sure how to do this. any idea? i was trying to add a line containing something like that:

LoadModule perl_module ../apache2/mod_perl.so

but i don’t know where to add this line... httpd.conf? apache-httpd.conf? apache2-httpd.include.conf? sorry, but maybe you can explain me what is the difference between all this httpd configuration files...

thanks a lot.

regards,

patrick.

Sorry but I'm not that skilled on Suse, since I use Debian.

But I assume you should activate mod_perl and dbi on your apache server (is it Apache2, right?)

For example, on Debian I should install apache, dbi and mod_perl by issuing:

apt-get install apache2

apt-get install apache2-perl-mod

apt-get install apache-dbi-perl

then, I put a file /etc/apache2/conf.d/otrs containing the following directives:

# --
# added for OTRS (http://otrs.org/)
# $Id: apache2-httpd-new.include.conf,v 1.3 2007/04/16 12:11:53 martin Exp $
# --

# agent, admin and customer frontend
ScriptAlias /otrs/ "/opt/otrs/bin/cgi-bin/"
Alias /otrs-web/ "/opt/otrs/var/httpd/htdocs/"

#Persistent connections#
PerlModule Apache::DBI

# if mod_perl is used
<IfModule mod_perl.c>

# load all otrs modules
Perlrequire /opt/otrs/scripts/apache2-perl-startup.pl

    # Apache::Reload - Reload Perl Modules when Changed on Disk
    PerlModule Apache2::Reload
    PerlInitHandler Apache2::Reload
    PerlModule Apache2::RequestRec

    # set mod_perl2 options
    <Location /otrs>
#        ErrorDocument 403 /otrs/customer.pl
        ErrorDocument 403 /otrs/index.pl
        SetHandler perl-script
        PerlResponseHandler ModPerl::Registry
        Options +ExecCGI
        PerlOptions +ParseHeaders
        PerlOptions +SetupEnv
        Order allow,deny
        Allow from all
    </Location>

</IfModule>

# directory settings
<Directory "/opt/otrs/bin/cgi-bin/">
    AllowOverride None
    Options +ExecCGI -Includes
    Order allow,deny
    Allow from all
</Directory>
<Directory "/opt/otrs/var/httpd/htdocs/">
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>

# MaxRequestsPerChild (so no apache child will be to big!)
MaxRequestsPerChild 400

and, restarting apache, everithing works.

Hope this helps.

If you tell us what kind of operating system you use (Debian? Suse? Windows?), maybe someone can help you more accurately...

hi everyone,

i have loaded the OTRS support package which should analyze my system. well, after running this package i have two critical points to review:

Apache::DBI Apache::DBI should be used to get a better performance (pre establish database connections). Critical

Apache::Reload You should use mod_perl to increase your performance very strong! Critical

well i searched all over the internet and couldn’t find anything on this two points. as i guess, this is not really a OTRS issue but more a apache issue... unfortunately i am not really familiar with apache... so hopefully someone of you guys can give a clue.

thanks a lot.

regards,

patrick.
