Hi everyone.

I want to create a crawler with perl and run it on crowntab. The program should use DBI and DBD::Oracle to insert data into my database.

When crontab runs it, I get the following error in my mail box.

Can't load '/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: libclntsh.so.10.1: cannot open shared object file: No such file or directory at /usr/lib/perl5/5.8.5/i386-linux-thread-multi/Dynaloader.pm line 230.

my code is something like:


use Getopt::Long; 
use POSIX; 
use POSIX qw(setsid); 
use warnings; 
use Data::Dumper; 
use WWW::Mechanize; 
use DBI; 
use DBD::Oracle; 
use XML::Twig; 


#do something----- 

sub init_env 
    $SIG{'INT'}  = 'IGNORE'; 
    $SIG{'QUIT'} = 'IGNORE'; 
    $SIG{'TERM'} = 'IGNORE'; 
    $SIG{'PIPE'} = 'IGNORE'; 
    # signal(SIGPIPE, SIG_IGN); 
    $SIG{'CHLD'} = 'IGNORE'; 

    my $pid = fork(); die "$!" unless defined $pid; exit 4 if $pid; 

    POSIX::setsid() or die "Can't start a new session: $!"; 

    # Flush standard output buffer. 
    $| = 1; 

        $ENV{ORACLE_HOME} = "/u01/oracle/product/10.2.0/client_1"; 
        $ENV{PATH} = "/bin:/usr/bin:/u01/oracle/product/10.2.0/client_1/bin:/home/appowner/bin:."; 
        $ENV{LD_LIBRARY_PATH} = "/u01/oracle/product/10.2.0/client_1/lib"; 

END { 


I have installed both DBI and DBD::Oracle with CPAN.

Please help and many thanks.


Hey I have figured out there is something wrong with my DBD installation, I corrected it and it run fine when I do it manually on command line, but still getting same error when crontab calls it. I read it on some other site that people suggest to set LD_LIBRARY_PATH to point to where the shared library is. But as you can see, I have set it to the location where "libclntsh.so.10.1" is located. =(

What user does the crontab run as? Does it have the rights to read that file?
