Subject: Oracle minimum install for perl DBI on Linux
Message-Id: <3958E367.E18EB1A8@irelands-web.ie>
Hi all,
I'm trying to set up a linux machine so that I can access a remote
Oracle 8.0.5 server using DBD::Oracle. I don't want to have to install
all of oracle on my machine, but I can't seem to find any reliable
information about what files I need to copy over in order to get
DBD::Oracle to compile. Any info I could find was about Oracle 7 and
doesn't seem to apply. I've copied over just about all the files from
the machine
with Oracle installed on it, but I still can't get it to work.
I just get the following when I run perl Makefile.PL
The ORACLE_HOME environment variable must be set.
It must be set to hold the path to an Oracle installation directory
on this machine (or a compatible archtecture).
See the README.clients file for more information.
$ORACLE_HOME is set.
Has anyone done this before? Can you let me know what files you
required? Alternatively, does anyone know of a good website where I can
find this info?
Thanks,
Kathryn.

Subject: Perl/cgi newbie questions
Message-Id: <3958E801.AE4569BD@burgoyne.com>
I am trying to learn Perl/cgi on a caldera linux box. I have a sample
program that was copied from the MySQL & mSQL O'REILLY book. the sample
program is shown below.
#!/usr/bin/perl -w
print <<HTML;
Content-type: text /html\n\n
<HTML><HEAD><TITLE></title><head><BODY>
<p> Environment Variables
<p>
HTML
foreach (keys %ENV) {print "$_: $ENV{$_}<br>\n";}
Print <<HTML;
</body></html>
HTML
When I access this program through my web browser, I get an "internal
error. Looking at the error_log it would appear that the Print <<HTML
lines are the problem. the error message indicates that they are not
numeric and appearently the << is the numeric left shift operator.
Question is What was the Print <<HTML line supposed to do?
Regards
Rick

What do you mean by a "generic function"?
What do you mean by "what widget called the function"?
How does a widget call a function?
Perhaps you mean a method call, something like:
$widget->method();
In this case, the first argument to method() is a reference to the
widget itself.
sub method {
my $widget = shift;
...
}
But this assumes that you have access to the internals of the widget,
which is very possible, but is not recommended unless you know what you
are doing.
Your question is not clear. Show us your code, and what you are trying
to achieve, and we'll help you further.

The former is easy. Have a log-in feature on a non-public web page. The
resellers can log in and you only display their records. They can add,
modify and delete records.

A simple SQL statement will do this ...

Depends what you mean. Database are by their very nature searchable. SQL
statements will extract the required information (see the previous
comment for an example). What you want can certainly be done, but you
need to supply more info before we can give a detailed answer.

There's no best or absolutes. Most languages will handle this easily. I
favour ASP as it's fast and very easy. ASP has strong database support
built in from the bottom, and if you program in VBScript it's very
simple[1]. There are huge numbers of samples and examples awaiting you,
so you'll have no problem learning it.
Hope this helps
[1] I'm not saying that other languages won't be easy, but VBScript is
about the easiest language I've ever learnt and it comes built-in with
ASP.
P.S. Please be a little more careful about which newsgroups you post to.
This question is not relevant to ASP components, and having posted in a
Java database group, it's pointless posting to a general Java group as
well. Follow-ups set.

Subject: Redirect
Message-Id: <OCCAOFF4$GA.281@cpmsnbbsa07>
I am trying to use a Perl script for CGI Programming.
The idea is that the user (using an HTML form) logs in on one page, and then
a perl script will validate the login and then redirect the user to either a
valid or invalid login page. I would rather use an ASP page to display valid
info but how do I get perl to redirect me to that ASP Page?
I tried this:
print redirect(-location=>"http://location/index.asp" ,-nph=>1);
But I get an error 302 saying Location has moved or something. I tried it
with other internet pages and it didnt work still. What is up with this? The
Perl script works except for this.

Umm if that is the actual line of code from the program you're writing I'll
have about as much success showing you you're error as I helping you find
the "any" key on your keyboard =)
Let see if this makes sense.
my $link_i_want_to_redirect_to = "www.thisisabigoldtest.com/page.asp";
print redirect(-location=>$link_i_want_to_redirect_to,-nph=>1);
If you leave location as the link you are going to it will try to bounce the
users browser to http://location which will of course die. Hope this helps!

I realize that the whitespace/something/@/something/whitespace
expression isn't ideal .. but (and forgive me if I'm just too dense to
get it) it seems like it would catch most email addresses .. and
probably suffice for this specific task.
I'm not arguing that there aren't better (more thorough) ways to search
for email addresses, but if I can't even write an expression this basic,
HOW will I write a more complex expression. (whew .. that was a long
sentence!)
My goal is to learn how to write this simple expression .. then keep
expanding on it until I have what I need.

Spaces ARE allowed, but only if that phrase is between quotes.
"fred and barney"@something.com

You don't tkae MSOutlook as THE reference, do you? If Microsoft fails to

And conversely, hyphen is *not* a special character, so you

Hi Drew,
Actually, we're not using anything right now. At this point, I'm just
updating all the information they submit monthly. However my new job doesn't
allow me to do this. I'm not looking for a programmer, I was hoping someone
would know of a script that was already available, that would be customizable
for something like what we need. I am not a programmer but I have customized
a few scripts for other non-profits that I volunteer with. I'm looking for
some suggestions that may help save me some time and help this group as well.
I've looked into using databases but don't honestly know much about them. I
need to be able to allow each chapter to update only their own information,
as such each chapter must be allowed to have their own password. Does that
make sense? As I mentioned, I'm just a volunteer and know so much, and was
hoping for some direction here.
Thanks for your help, I really truly do appreciate it.

Subject: Staus of Perl Compiler and other questions
Message-Id: <8jaf8l$ch3$1@nnrp1.deja.com>
I've been trying to determine the status of the Perl -> C compiler, but
am a bit confused about what it currently is. The man pages accessed
via perl.com still flag the B:: module as 'experimental', and in the
full module list this has an Alpha/Beta test status. However, it is
released as a core module, the manpage for the perlcc frontend implies
everything is OK, and it even made it into the Perl in a Nutshell book
published early in 1999. Am I simply seeing some out of date references?
While on this, I've tried running it, and get a couple of messages I
don't understand, and haven't been able to find any documentation about.
<class> has method new: - -u<class> assumed
I imagine that it is guessing that the class has an object constructor,
and is flagging some option because of that. I have a lot of other
classes whose constructors are not 'new' - should I be doing something
special with these?
and lots of messages of the form...
No definition for sub Fcntl::F_SETOWN (unable to autoload)
Do I need to do anything with these?
Thanks and regards

From what I've read, look for coverage of the perlcc and friends in
the next edition of Programming Perl.
From the beta sample chapter on the ORA website, I read this:
::The standard but currently experimental perlcc(1) command knows how
::to convert Perl source code into a byte-compiled Perl program. All
::you have to do is: (...)

You should probably wait until the effects of the psychedelics
wear off before posting to Usenet, heh, heh.
You seem to be referring to 3 (or is it 2?) *different* books
as if they were the same book.
I do not know of any Perl book authored by "Andrew Johnstons",
or even by "Andrew Johnston's".
1) "Programming Perl" (aka "Camel"), Wall, Christiansen, Schwartz
2) "Effective Perl Programming", Joseph Hall
3) "Elements of Programming with Perl", Andrew Johnson

The answer is already on your hard drive. Why should we

Subject: Upgrading 5.6 to use 64 bit
Message-Id: <8jamtr$j4u$1@nnrp1.deja.com>
I recently upgaded to perl5.6, but I am not sure if I am using the 64
bit capablility. I installed using the defaults, so I don't think I am.
How do I upgrade to use 64 bit capablility with out uninstalling /
reinstalling?

Now there's a useless 3rd parameter.
If you worry about optimization and avoiding useless splitting, well,
perl will do it for you.

You didn't test this did you?
This doesn't return what you expect. You are getting the result of
split() in a scalar context, which returns the number of element split()
returns. Also, -w would have told you so.
Moreover, you don't need to escape the @.

Why not use uc() instead of \U? \U uppercases everything until \E or the
end of the string. You don't have any \E's.

And it doesn't produce the correct output.
Please test all your code snippets before posting to the
newsgroup. Wrong code will confuse newbies more than help them.

1) Neither of those win a golf contest for generating syntax errors
(which is what they both do :-)
2) <STDIN> and <> are not equivalent (generally).
They are equivalent only if @ARGV is empty (or contains hyphen).

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.

To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
