The confusion comes from the fact that the line of code above is PHP, in
which you can open a URL just like a normal file.

Message-Id: <8euf5f$mj6$1@nnrp1.deja.com>
Help,
I have installed Oracle 8i (8.1.6) on Sun Solaris 7. I have installed
the latest version of production perl 5.005 and now I'm trying to build
DBD and DBI.
The make and build of DBI 1.13 seems to work, test, and install fine.
The make and build of DBD 1.03 will build but always fails the "make
test" with an error that simply says "You need a
Solaris patch to run this version of java runtime". No mention of what
patch.
I've gone to sunsolve and called Sun ... no help.
I've gone to metalink and called Oracle ... no help.
Let my people go. I need an answer.
I realize that ORACLE_HOME/JRE is a link to the Oracle JRE 1.1.8, but
you must use this version with Oracle.
Someone must have figured this out.
Thanks,

Some webbrowsers keep all cookies in RAM until you quit 'em, maybe that's it?
Here's some code that will show you how to make your own cookie and how
they then look (watch out for linebreaks that might have been added):
-----
sub the_swedish_cookiemaker() {
# (c)2000 svanstrom.com
my($name,$value,$stay,$path,$domain,$sec) = @_;
if (($domain =~ tr/\./\./) < 2) {$domain = ".$domain";}
my(@days,@months,@temptime,,@ends,$cookietime,$i);
@days = ('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
@months = ('Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec');
(@temptime) = gmtime(time+$stay);
$cookietime = "@days[$temptime[6]],$temptime[3]-@months[$temptime[4]]-".($temptime[5]+1900)." ";
@ends = (':',':',' GMT',);
foreach ($temptime[2],$temptime[1],$temptime[0]) {
$i++;
if ($_ < 10) {
$cookietime .= "0$_$ends[$i-1]"
} else {
$cookietime .= "$_$ends[$i-1]"
}
}
return("Set-Cookie: $name=$value; expires=$cookietime; path=$path; domain=$domain; $sec\n");
}
print &the_swedish_cookiemaker('namn','value',60*60*24*365,'/','.yourdomain.tld',0);

Warnings are not errors:
$ cat test.pl
eval {
die "Error in eval 1.\n";
print "Still alive in eval 1.\n";
};
print "Caught: $@" if $@;
eval {
warn "Warning in eval 2.\n";

Caught: Error in eval 1.
Warning in eval 2.
Still alive in eval 2.

So this would be a non-Perl script then? What scripting languages
does your host allow you to use? And why are you asking this question
in a Perl newsgroup?

Well, first of all, most any good book on CGI programming will show you
how to get some input from a web page. The second part of what you want
to do is much harder. Remember that the CGI is going to run on the
server so the user has to enter a uid and pw that are valid there. Then,
its not clear if you mean to have some command execute as though the user
were really logged on. If so, I believe you are SOL. There has recently
been a discussion about doing a su inside a perl script and the
conclusion reached is that you cannot.

Where did you run your script? How are the permissions set for that
location?
What does the script look like?
Some more input, please!

Yes but can the script be executed by you?
Try:
chmod +x script
This has nothing to do with perl it applies to all scripting languages
on Unix.

How did you execute it?
It is possible, that you should alter the permissions for the file,
especially execute (e.g. chmod u+x file)
look it up in
man chmod

Did you remember to chmod +x your script? Have you got the first line of the script correct (something like: #!/usr/bin/perl) I believe both of these will
cause a permissions error.

Thank you. But when I enter
pod2html perlvar.pod outfile=c:\perl\perlvar.html
and variations of that, with or without the file name in quotes, it
always comes back saying:
Can't open outfile: No such file or directory at
C:/Perl/lib/Pod/Html.pm line 365, <POD> chunk 375.
Then it gives me 25 lines, each telling of something it can't resolve.
For example:
pod2html.bat: perlvar.pod: cannot resolve L<BUGS> in
paragraph 48. at C:/Perl/lib/Pod/Html.pm line 1561.
But there is a happy ending. I eventually noticed somehow that
pod2html.bat uses something called html.pm, and then I found that I
have the source for that. I was able to modify the 'open' statement
for the output file in html.pm, and I then got my HTML file.
It also helped to open STDERR to go to a file, so that I could get the
error messages to sit still while I looked at them.
But it still gave me the 25 lines of things it couldn't resolve.

Of course not. You forgot the hyphen/minus sign in front of "outfile".
You may also need to keep the filename perlpod.var for last.
You can also try
pod2html perlvar.pod >c:\perl\perlvar.html

IMHO it depends on the kind of work and Data
that you are doing in your new-method.
Anything which is dealing with initialisation
should be done in an extra init-subroutine which
can be called from within the new-method.

It is not a must, to name that method new(),
although a lot of people are doing so.

It's not code, it's pseudo-code using the syntax of Perl. This should
be blantently obvious since I'm taking about something that AFAIK
can't be done in Perl. We are for ever telling people to write
pseudo-code following Perl syntax.

You are just deliberately pretending to dense, please stop it. I know
you are not relly that dense. I _know_ Perl does not have lazy
evaluation in this situation, what I'm asking is if there is some why
to fake it.

Given a prefix of string and a pattern is it possible to test if is
necessary to read in more to know if (or what) the pattern will match
in that prefix.
If you find the previous pseudo-code un-helpful then try this actual
code:
need_more("foo", qr/f/) # Matches => false
need_more("foo", qr/o+/) # Matches but we dont know how many => true
need_more("foo", qr/od/) # Don't know if is maches => true
need_more("foo", qr/d/) # Doesn't match => false
So my question is can we construct the need_more() function using Perl?

Yes, and ESA used ADA to get the Ariane V debacle...

Which one would be slow? The one delivering the records through HTTP?
This about access file was silly, but would it be slow too, if I would
do a "select * from table* query via Perl/PHP3, and send the records
through normal http port, the client would recieve the records and
sttore them localy. Would it be slow, too? We are talking pure ASCII
here, would binary transfers be somewhat faster?
What is a 3-tier solution?

I've downloaded a a 164k DBI module from CPAN. Is there anything more I
need? I don't understand how do I set the DSNs in ODBC up to use such
a proxy? Or it can be used by a perl on a client only? Does the proxy
listen to specific port all the time? The root might not like that :(,
and I'd have a restart problems (would have to use at to start such a
proxy).
This sound like a good moment for the following question...
Can I install/use Perl modules without having the root to install them
globaly? I guess I could do a 'perl Makefile.pl', and a make, too. I
also guess I could use some calling convention to call the module with
a given path, right? The thing that confuses me is that there are loads
of users asking the root to install some Perl modules taht they want to
use...

It was released a few weeks ago. <www.perl.com> says it is stable. (See
top line of text in home page.) Well, I've read that they have worked
around 2 years on this, so I would hope it is stable.
The only problem you can have is, especially (only?) when using
Activestate Perl on Windows, that not all modules available for 5.005
have already been ported to 5.6.

Depends on your definition of stability. Have a look at
bugs.activestate.com for the current 'issues'.
