Perl Oracle client manual installation to home directory in Debian

I need to connect to the Oracle database in my work to get some data from it. I'm not the Oracle expert, but I decided to use DBD::Oracle.

Most of the manuals and how-to pages describe, how to install client libraries to system (usually as root), which was not my case.

I just need one directory with libraries in my $HOME and few scripts to get some data from the database - no system installations.

Here are the steps how to install DBD-Oracle and it's libraries to "one" directory without doing mess in the system:

First let's install core system related libraries and tools
aptitude install gcc libdbi-perl libaio1 libstdc++6-4.4-dev unzip 

Get the Oracle client libraries from their download page
mkdir $HOME/lib/ && cd $HOME/lib/
wget basiclite- sqlplus- sdk-
unzip *.zip

Install DBD::Oracle:
wget http://search.cpan.org/CPAN/authors/id/P/PY/PYTHIAN/DBD-Oracle-1.24a.tar.gz
tar xvzf DBD-Oracle*.tar.gz
cd DBD-Oracle*

export LD_LIBRARY_PATH=$HOME/lib/instantclient_11_1
export C_INCLUDE_PATH=$HOME/lib/instantclient_11_1/sdk/include

perl Makefile.PL PREFIX=$HOME/lib
make && make install

Now you should have DBD::Oracle installed in your $HOME/lib directory.

You can modify this short script to see if it's really working:
#!/usr/bin/perl -w
use DBI;

push (@INC,"$ENV{'HOME'}/lib/lib/perl/5.10.1");


#lsnrctl services - to find right sid

$dbh = DBI->connect("dbi:Oracle:host=$host;sid=ORCH3;port=1521", $user, $passwd);
  or die "Couldn't connect to database: " . DBI->errstr;

my $sth = $dbh->prepare("select * from tab") 
  or die "Couldn't prepare statement: " . $dbh->errstr;

$sth->execute() or die "Couldn't execute statement: " . $sth->errstr;
while (my ($table_name) = $sth->fetchrow_array()) {
    print $table_name, "\n";

I believe you can install DBD::Oracle without dependencies above like gcc or libstdc++, but I'm fine to install these.

  1. Hi,

    Just wanted to say thank you for this detail as i have tried unsuccessfully for the last couple of days to get this working (using the many links found by google). The target system has to be slim and will be installed by engineers, so i need a complete solution!! Thank you !
