How to set LD_LIBRARY_PATH
Hi all,
Can someone advise how to set LD_LIBRARY_PATH from within the Perl scripts?
If I set LD_LIBRARY_PATH from the command line, all is okay
[oracle ~]$ perl -e 'use DBD::Oracle; print $DBD::Oracle::VERSION,\n;'
Can't load
'/oracle/product/db/11.1/perl/lib/site_perl/5.8.3/x86_64-linux-thread-multi/auto/DBD/Oracle/Oracle.so'
for module DBD::Oracle: libclntsh.so.11.1: cannot open shared object file:
No such file or directory at
/usr/lib64/perl5/5.8.5/x86_64-linux-thread-multi/DynaLoader.pm line 230.
at -e line 1
Compilation failed in require at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
[oracle ~]$ export LD_LIBRARY_PATH=/oracle/product/db/11.1/lib
[oracle ~]$ perl -e 'use DBD::Oracle; print $DBD::Oracle::VERSION,\n;'
1.15
But if I do the following instead in the Perl script, it does not work? How
to set the LD_LIBRARY_PATH then?
$ENV{ORACLE_HOME}=$ORACLE_HOME;
$ENV{ORACLE_SID}=$ORACLE_SID;
$ENV{PATH}=$ORACLE_HOME/bin:$PATH;
$ENV{LD_LIBRARY_PATH}=$ORACLE_HOME/lib;
FYI, the script is to run from a cron which is why am setting
LD_LIBRARY_PATH in the script.
Any response will be very much appreciated. Thanks in advance.

Try putting the %ENV adjustment in a BEGIN block that executes before you load
the Oracle driver.

You could do one of two things instead of tweaking %ENV in your Perl script:
(1) In your crontab, set the variables in the cronline:
* * * ... BLA=eins BLUB=zwei /usr/local/bin/script.pl
(2) Call a shell script from the crontab that sets up the environment for your
Perl script and then calls it.
I'd go for (2).

Re: How to set LD_LIBRARY_PATH
You will have to set those values before your modules load.
So you should stick them in the BEGIN and that should work

If you're going to use use DBD::Oracle; in the script then you'll need to
put these statements in a BEGIN block:
[code]
use vars qw($ORACLE_HOME $ORACLE_SID);
BEGIN
{
$ORACLE_HOME = ...;
$ORACLE_SID = ...;
$ENV{ORACLE_HOME}=$ORACLE_HOME;
$ENV{ORACLE_SID}=$ORACLE_SID;
$ENV{PATH}=$ORACLE_HOME/bin:$PATH;
$ENV{LD_LIBRARY_PATH}=$ORACLE_HOME/lib;
}
use DBD::Oracle;
[/code]
That's because use is executed at compile-time instead of run-time.

Re: How to suss out module dependencies...
One difference with what I did is that mine determines if the mod is a core mod and does not list it, if so. I was trying to parse through all of our homegrown packages and see what non-core mods (and versions) they depended on. didn't spend a lot of time making it prettier, so some calls were system calls to start perl within perl (seems yucky) and parsing STDOUT response, but it seemed to do the job, so it remained ugly... I agree with Dave about the fact that your setup should not need to be CPAN compliant in order for you to still get the dependeny list you want if you use CPAN::FindDependencies. bruce David McMath wrote: We dealt with a similar problem, moving from comfortable old server to a shiny new one. Perlmonks had some interesting advice: http://perlmonks.org/?node_id=203148 which I think is pretty cool (even though I only barely understand what it's going). One of our folks ended up, though, using the CPAN::FindDependencies module and writing some stuff that walks up through our use statements until it finds something that's not ours, then asks CPAN. You mention you're not using the normal CPAN model, but FindDependencies acutally goes back to a cpan site to get its answers, so maybe that's OK. Maybe this is helpful, dave William Bulley wrote: I have a question for which I have not been able to find a good answer. I have a Perl application that uses many Perl modules. Most come from CPAN, some I have written, others come with Perl distributions (core?). I am faced with the need to transport this collection of Perl code from operating system A to operating system B, both of which are perfectly well supported by Perl. Over several months I have added to system A lots of modules that need other modules. Unfortunately, system B is rather devoid of most of the modules that I need for this application. I dread having to make an inclusive list of all the modules and all the modules that those modules need, and so on, and so on. This is something that CPAN does when I install a new module that has dependencies on other modules. BUT in my case I am NOT using the blib, lib, t, MANIFEST, etc., etc., distribution model of CPAN, so I cannot use those tools - including several others on CPAN that compliment or implement this functionality. So my question is: is there a way to ask the Perl compiler/interpreter to spit out all the modules (and the other dependent modules) in my application in some format (a structured tree, a linear text file, etc.)? Failing that, are there some external tools that can accomplish this given my main module as a starting point? Thank you in advance.

RE: How to set LD_LIBRARY_PATH
A workaround for LD_LIBRARY_PATH for me is to locate my Java jvm.dll in
$JRE_BIN/bin/server and the resource dlls are in $JRE_HOME/bin
the other libraries are on $PATH

DBD::ODBC 1.24_1 development bug fix release
Due to annoying bug a few people are hitting when re-executing a prepared statement with MS SQL Server I've uploaded 1.24_1 development release. Changes since 1.24 are: Corrected pod and private attributes for the odbc_SQL_DRIVER_ODBC_VER attribute which was documented as SQL_DRIVER_ODBC_VER. Added FAQ on pauses on statement destruction when all the result-set has not been retrieved (mostly freeTDS and MS SQL Server ODBC Driver). Fixed bug introduced in 1.24 where if you are using MS SQL Server, and you are preparing, binding placeholders and re-executing multiple times you may get a Invalid character value for cast specification error. Thanks to anonymous for spotting this and producing a standalone example of the problem that made it so much easier to find. Martin -- Martin J. Evans Easysoft Limited http://www.easysoft.com
Re: How to set LD_LIBRARY_PATH
The dynamic loader read LD_LIBRARY_PATH when (before?) Perl gets going. AFAIK,
it doesn't reread it, so changing it in Perl code is too late unless you set
it and exec your code again (which is basically saying it is too late).
I'm tolerably certain this applies to Solaris; I think it applies elsewhere too.
