Re: ORA-12154: TNS:could not resolve service name with DBI under Apache
The ORACLE_HOME ___environment___ variable is set where? I see no indication
of it being set in any of your examples or config.
I do see PerlSetVar setting it-- don't confuse that with the environment!
PerlSetVar is a specific way to set variables so mod_perl can read them via
the dir_config() method.
I usually set my ORACLE_HOME inside my startup.pl so all the Apache children
can definitely find it:
$ENV{ORACLE_HOME}='/disc1/sherpa/oracle';
You might also be able to use Apache's SetEnv directive, see the following
URL for details and possible restrictions:
http://www.apache.org/docs/mod/mod_env.html#setenv
And finally, you should double check your case in your DSN during your
connect(). Oracle SIDs might be case sensitive and thus not finding the
proper SID. (I always have SIDs that are all capital letters, so I couldn't
tell you for sure.)
Hope this helps.

The ORACLE_HOME is well set ! I first tried to use Apache::DBI but i get

My scripts run well if I launch it from the command line.

Re: ORA-12154: TNS:could not resolve service name with DBI under Apache
Thanks Jeffrey but:
- the tnsname.ora is OK as tnsping works fine as well as the same script run
from the command line.
- the case is only important for Oracle in the string dbi:Oracle:SID
(the line in startup.pl in commented it was just a previous try)
I'm really running out of idea about this problem. I never had any problem
with DBI
in other command line perl scripts as well as in traditionnal perl CGI
scripts so I
think there is something linked to Registry ???

Jerome

Re: ORA-12154: TNS:could not resolve service name with DBI under Apache
David,
The ORACLE_HOME is set in the httpd.conf with a PerlSetEnv directive.
(it appears in the extract I sent). (I've checked that is OK in the scripts by
printing out $ENV{ORACLE_HOME} )
The SID is not case sensitive (I tried some combination when I was trying to
figure out what happen) otherwise it would mean that SID are insensitive when
running the script from command line and sensitive when running from Apache !
Thanks for you help
Regards
Jerome

My mistake, Jerome.
PerlSetVar != PerlSetEnv
I read that as PerlSetVar. Sorry to confuse the issue.
I hope it's a simple permissions problem.
Good luck!

Well I can pretty much guarantee you that the ORACLE_HOME environment is not
being set by PerlSetVar. That is simply not the function of PerlSetVar.
You must have it set globally in /etc/profile or similar if you're able to
print it. And if you are indeed able to print it, then it not being set is
not your problem.
Just to humour me, please set it in your startup.pl like my example shows,
and remove the PerlSetVar line in your httpd.conf. Try again. If the problem
persists, it's something else. Maybe permissions...
Does the webserver user have rights to look at tnsnames.ora and other
items inside /disc1/sherpa/oracle? To verify, su into your webserver user
and attempt to run your script from the command line.
The SID is not case sensitive (I tried some combination when I was trying to
figure out what happen) otherwise it would mean that SID are insensitive when
running the script from command line and sensitive when running from Apache !
OK. It's not case sensitive. I've learned something new today, and verified
by reconfiguring my tnsnames.ora.
Good luck.

Re: ORA-12154: TNS:could not resolve service name with DBI under Apache
A final effort... From the command line it works. Perhaps your ORACLE_USERID,
etc. is already set?
Within your Registry script, that's probably not the case unless you've
explicitly told it otherwise.
So let's change your DSN around a bit:
my $dbh = DBI-connect('dbi:Oracle:', 'indic/xxx@INDICATORS', '',
{ AutoCommit = 0, RaiseError = 0, PrintError = 1 } ) or die $DBI::errstr;
I don't use the same format of the connect string that you are showing in
your example below (I use the format above.) In fact, I vaguely remember
encountering a similar problem when using a 'typical' connect string with
other DB's.
I'm hoping that something in your current environment is set allowing that
format to work, when in actuality it's the improper way.
Let's see if this works. If not, I'm out of ideas. :-(
Good luck!

Have you tried something like:

explicitly supplying the server and avoiding the `use XXX' on the
