in thread Can't locate DBD/Oracle.pm

Hello! Thanks once again for your reply. I apologize if I wasn't more clear. I installed the DBD::Oracle package via cpan. I was having a tough time getting a manual download of DBD Oracle from the cpan site to work. So once I discovered the correct proxy settings for my network I decided to give the automated cpan a shot.

Normally, were this linux I would simply use locate, but as this is a solaris 10 machine best I could do was a 'find' for Oracle.pm. This is what I was able to turn up.

The reason you see Oracle.pm in this location (/usr/perl5/site_perl/5.8.4/sun4-solaris-64int/DBD) is that in my experiments to get this to work I tried moving the Oracle.pm driver to the same place I found a bunch of other DBD drivers. Here's a listing of that directory:

It fails at line 19 which is this line:

which resides in this block of code:

I was just wondering if there might be any other tricks that I've missed that might get this working. I certainly appreciate any input you may have.

Thanks

    That long list of dirs containing Oracle.pm files all seem to be within your Oracle installation and not within your Perl installation except for the ones:

    005 /usr/perl5/site_perl/5.8.4/sun4-solaris-64int/DBD/Oracle.pm
006 /usr/local/lib/perl5/site_perl/5.8.5/sun4-solaris/DBD/Oracle­.pm

    [download]

    The above suggests to me you have multiple Perls installed. Is /usr/bin/perl a symbolic link perhaps? I think you have not installed DBD::Oracle into the Perl you are using. The script you previously quoted started #!/usr/bin/perl and you presumably ran it with ./myscript.pl but we don't know if you have another Perl on your PATH (one perhaps you were using with the CPAN shell). So, what does "which perl" return and what happens when you run:

    /usr/bin/perl -le 'use DBD::Oracle; print $DBD::Oracle::VERSION'

    [download]

    Now repeat without a specific path e.g., just perl -le....

    If it is not installed, download it and install it yourself. Although installing DBD::Oracle via the CPAN shell is possible you really need to set ORACLE_HOME or LD_LIBRARY_PATH (when using Instant Client) and set ORACLE_USERID, TWO_TASK etc to run the tests.

    Also, I don't believe changing LD_LIBRARY_PATH in your Perl code will work. I believe it needs to be set before you run your script.

    Lastly, don't just blindly copy module files around, it often won't work and nearly always won't work when there is some XS code and hence a shared object that goes with the module.
