This occurred to me in the case of Oracle (one of my co-workers was facing a very similar problem in the preliminary stages of one of his designs), and I actually had asked our DBAs about this (since the Oracle SQL*Plus also allows you to change users). As I suspected (from the similar "connect" terminology), our DBAs confirmed that Oracle just does a disconnect and reconnect under the hood. I would bet the psql client does the same thing. I don't have a PostgreSQL installation handy at the moment, but I seem to recall it has a statement logger similar to MySQL's... if you have it handy, you could try the \connect from psql and see if it results in a disconnect and reconnect.

I think so too. I,m no Perl guru, but I know from my personal
experiance that it works fine under unix and cygwin, but I _always_ have
had to manually do this under normal Win32 (I know, I know, I never
submitted a patch... I guess the reason was because I never [finally]
compiled mod_perl for Win32 and had enough strength left to diff the
Makefiles... :-( )

Re: AddModule mod_perl.c
Hi Dan, You are correct when you refer to 'this somewhat convoluted load/clear/add' My httpd.conf has LoadModule perl_module libexec/libperl.so AddModule mod_perl.c When I leave alone and check the error_log, Apache AND mod_perl are loaded. However, I cannot view any web pages; instead I get the msg: 'The document contained no data' (what document I do not know) When I comment out the AddModule I can view all my web pages, but the error_log claims that only Apache is loaded - mod_perl is not. This may be fine, it may be a DSO (I don't know) but I cannot view a .pl file as outlined in Apache Modules w/ Perl & C, pp 41-45. It displays text only, as if the Options ExCGI were not present. I am trying to pay close attention to the guide and all the other literature on the subject. Obviously, it the installation works correctly the first time, then it is understandable, otherwise, (I think) it is very confusing.

You'll have to incur a connect on each HTTP request. What would be ideal is if the database would allow you to change the user on the current connection. I know PostgreSQL will allow this using the command line interface psql tool (just do \connect ), but I'm not sure if you can do this using DBI. If this was possible, then you could always connect to DBI using the same username/password so Apache::DBI gives you a cached connection, and then once you have the connection, you can change to the user you want.

Frankly, hardly anyone does that. Most people refer to the guide on-line. I've used mod_perl for years, referred to the guide frequently, and never downloaded it. If you have to work over a slow link I can understand why you might want a local copy, but a quick wget command can mirror it all for you pretty easilly. People usually only download the CPAN package if they're planning to do some hacking on it. Mentioning the module dependency in the text next to the download link is probably a good idea, and offering a .tgz of all the generated HTML files as well as the PDF, but I think you may be the first to request such a thing. > It's hard enough to install mod_perl itself.

The things that That explains why Embperl did so poorly compared to PHP, yet when we replaced our PHP pages with Embperl, our benchmarks using real user queries, sending the same queries through the old and new pages, the new pages showed a 50% performance boost. Note: that gain was enough to saturate our test network. Our purpose for the benchmark was to determine if it was an improvement or not, not to determine the exact improvement, so we don't really know what the real gain was. The same machines do several other tasks, and our monitoring at the time of change was not very sophisticated, so we only really know it was a big win.

I think you've confused LoadModule and AddModule. If you follow the recommended apache configuration, which does all the LoadModules followed by a ClearModuleList and a bunch of AddModules, you don't need the LoadModule for mod_perl (since it is built in), but you do need the AddModule since *all* the module entries get cleared by the ClearModuleList. I believe the point of this somewhat convoluted load/clear/add procedure is for the static modules to end up in the right spots in the module list relative to all the DSOs, rather than all bunched up at one end, since the order does matter (a lot). -- Dan Riley [EMAIL PROTECTED] "Mr. Ellison is presently the sole member of the Plan Committee.

Re: Cookies and IE in mod_perl
I've determined that it isn't the redirect causing the cookies not to be set.
If I take out the redirect, and just try to set a cookie w/o a redirect, it
still doesn't set the cookies in IE. Does M$ have any docs on how IE6
handles cookies that I can look this up on?

This is a module, available off of CPAN: http://www.cpan.org/modules/by-module/Pod/Pod-HtmlPsPdf-0.04.tar.gz (Written by Stas, in fact!) It allows you to create HTML, Ps (Postscript) and PDF documents given POD. What is POD (or Pod)? "Plain Old Documentation". This is the native documentation format for Perl modules. For any perl module you have installed on your system, you can read its documentation by the "perldoc MODULENAME" command. The perldoc command will scan the module for its included POD, and then render the POD for your reading pleasure. -- What is CPAN? CPAN is the Comprehensive Perl Archive Network. It is a vast collection of user-contributed Perl modules that cover a vast array of common (and not so common) tasks that you might wish to cover. It will simplify your life greatly. There is an installation procedure that you can follow that will allow you to take a module off of CPAN and put it on your computer. There is documentation available on the CPAN web site, http://www.cpan.org/ that you can read and learn and therefore allow you to install the modules. (Usually it's not difficult to install a module -- you should usually be able to do it in 5 command lines, or less if you don't mind stringing a bunch of them together with "&&" logical joiners.) There is a module available on CPAN called "CPAN" that, if you already have it installed on your system, can greatly ease your task of installing modules off of CPAN. If you have it installed, I suggest you use it. If you don't have it installed, I suggest you install it and then use it to install all future modules. -- How can you tell if you nave module Foo::Bar::Baz installed? perl -MFoo::Bar::Baz -e 'print "$Foo::Bar::Baz::VERSION\n";' If you have the module installed, this command will tell you the version of the module you have installed. If you don't have it installed, then it'll spew out a few lines regarding how Foo::Bar::Baz can't be found within the Perl module include path of your system. (called @INC) Note that some CPAN modules -- *including* Pod::HtmlPsPdf" -- have *dependancies*. Sometimes these dependancies are other Perl modules. (if so, then the CPAN module can automatically follow the depedancies and install the modules that are depended-upon and install them). Sometimes the dependancies depend on you having other *non* Perl programs (or libraries) installed on your system If you try to install a Perl module that has one of these kinds of dependancies and you don't have the thing that is depended upon on your system, then the module installation attempt will fail and you will have to go and install that thing first before you try installing your Perl module again. *Pay attention* to what the installation error report says -- it should provide you with the information (or at least the clues) you need in order to successfully install the module. -- How do you install pieces of software that aren't Perl that the random CPAN module that you're trying to install might need? That depends on your operating system. I use Debian GNU/Linux. Lots of people use RedHat based Linux systems. And then there's Solaris. And other Unices. And (gasp!) Windows OSes. Each one has a different way to approach this problem. It also depends on the program / library in question. I'll have to let you work on this part yourself for now, at least until you've put in a few hours of trying on your own and you can come back with a few specific questions. (i.e. "I need to install the following, I tried doing the following, it didn't work, and here's the error message I'm getting. My system setup is the following. What's going on?") -- Another useful piece of information -- you can read the POD of a module without it already being installed on your machine! You do this by going to www.cpan.org and looking info re: CPAN module documentation. There are several selections along these lines -- pick one, check it out, see if it gives you what you want, and if not then check out another one. Rinse, lather, repeat... I suggest you check out the Pod::HtmlPsPdf documentation online using this technique. Here's a direct URL, just because I'm such a nice guy... http://theoryx5.uwinnipeg.ca/CPAN/data/Pod-HtmlPsPdf/Pod/HtmlPsPdf.html -- Why am I going into so much detail? Because it seems like you haven't done this kind of thing before. Note that the mod_perl installation itself (if you aren't using some packaged module like an RPM or DEB or something like that) includes a bunch of outside dependancies. You'll always be faced with challenges when it comes to administe
the Guide
I recently downloaded the mod_perl Guide and tried to install it. Problem is that it would not install properly because the file: pod2hpp was missing. After trying other versions I kept getting the same error. Then I checked google.com. I am not the only one w/ this problem. I conclude that the guide is built from the PODs (Plain Old Documents). pod2hpp is thus needed to convert the pods to html. The online guide is no doubt created the same way. Wouldn't it thus be simpler and more convenient for 1st times like myself if the guide download were simply the already created html pages which appear online. Naturally they would be compressed. Then one would only have to uncompress them instead of building them. It's hard enough to install mod_perl itself. Why add an extra burden for the manual also. Thanks.

Hi Stas, I know the guide is posted on line. I would like to get a copy on my server to save on traffic. Moreover, I don't want a PDF copy - not as friendly (to me). Exactly what is Pod::HtmlPsPdf and how (and why) do I install it. Thanks.

The guide is all here: http://perl.apache.org/guide. You can even grab it as a pdf. To build it from sources you need to install Pod::HtmlPsPdf. If you were looking closely at the output when you run 'perl Makefile.PL' it should have told you that you are missing the prerequisite. > John Kolvereid > > > --- Ged Haywood <[EMAIL PROTECTED]> wrote: > >>Hi there, >> >>On Sat, 23 Mar 2002, John Kolvereid wrote: >> >> >>>Which Guide?

Although there are lots of qualifiers on those benchmarks, I consider them rather dangerous anyway. They are "Hello World" benchmarks, in which startup time completely dominates the time. The things that distinguish more sophisticated solutions from basic CGI or even modules are elements such as caching, pre-compiling and other techniques directly aimed at improving real-world performance.

Re: AddModule mod_perl.c
Unbelievable - Not only cannot I install and configure mod_perl, I can't even load the "guide". I downloaded Apache-mod_perl_guide-1.31 and untarred it. Then like the instructions dictate I entered perl Makefile.PL - ran ok make install The last instruction choked because it couldn't exec "pod2hpp". So I say "ok" it's the version. I try 1.30. The same. Then I read the readme on their web site. It says to get the latest POD sources. I download guide-cvs-snapshot_200203241203_tar.gz and untar it. Once again, the same: "pod2hpp" does not exist. Not sure the view is worth the climb.

Re: mod_perl training companies?
A young, startup company of 15 local people (believers) is doing traning and
development on mod_perl, web and system administration (Linux). We are
located in Yugoslavia, Belgrade but we also work with people and companies
from other countries (Canada, Germany, Cyprus, USA). Much of our expirience
comes from this mailing list, perl books and jobs we've worked on abroad. We
got a lot from open source community and we're giving it back.
Prices are very low since our country living standard is very low and there
are not many perl jobs around here, unfortunatelly.
We respect all the clients we have.
Our biggest accomplishment is in progress, since we've given a chance of
assisting in moving old cgi-bin applications to mod-perl for
www.cleverform.com (British company, rewiewed in January's edition of PC
Magazine). I hope in time to come you'll be able to put this site in Powered
by mod-perl section.
You can reach us at http://www.modperldev.com (a website we're making to
serve open community).
