1. 系统环境

系统版本：Fedora6 X86_64
DB2版本：DB2 v9.5.0.3
Perl版本： v5.8.8（系统自带）
Perl-DBI版本：perl-DBI-1.52-1.fc6（系统自带）
DBD-DB2版本：DBD-DB2-1.76

2. 安装DBD-DB2

下载地址：http://search.cpan.org/~ibmtordb2/DBD-DB2-1.76/

导入下面环境变量：
根据自己的系统安装的路径，导入相应路径。
export LD_LIBRARY_PATH=/opt/ibm/db2/V9.5/lib64
export DB2_HOME=/opt/ibm/db2/V9.5

安装步骤：
perl Makefile.PL
make
make test
make install

模块安装位置：
cat /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/DB2/.packlist
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/Bundle/DBD/DB2.pm
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/DBD/DB2.pm
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/DBD/DB2.pod
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/DBD/DB2/Constants.pm
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/DB2/Constants/Constants.bs
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/DB2/Constants/Constants.so
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/DB2/Constants/autosplit.ix
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/DB2/DB2.bs
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/DB2/DB2.so
/usr/share/man/man3/Bundle::DBD::DB2.3pm
/usr/share/man/man3/DBD::DB2.3pm

3. 测试脚本.

1). perl连接远程DB2服务器：
cat perl_connect_to_remote_db2.pl
#!/usr/bin/perl -w
$userid="db2inst1";
$password="passwd";
$db="sample";
$port=50000;
#$hostname="localhost";
$hostname="xxx.xxx.xxx.xxx";
$protocol="tcpip";
$conn_string = "dbi:DB2:DATABASE=$db; HOSTNAME=$hostname; PORT=$port; PROTOCOL=$protocol; UID=$userid; PWD=$password;";

use DBI;
$dbh = DBI->connect ("$conn_string",{RaiseError => 0}) or
die "Can't connect to database $hostname:$db: $DBI::errstr";
my $stmt = "select * from employee";
my $sth = $dbh->prepare($stmt);
$sth->execute();
my $col1;
$sth->bind_col(1,\$col1);
while ($sth->fetch) { print "$col1\n"; }
$sth->finish();
$dbh->disconnect();


2). perl连接本地DB2服务器：
cat perl_connect_to_local_db2.pl
#!/usr/bin/perl -w
$userid="db2inst1";
$password="passwd";
$db="sample";

use DBI;
$dbh = DBI->connect ("dbi:DB2:$db", "$userid", "$password") or
die "Can't connect to $db database: $DBI::errstr";
my $stmt = "select * from employee";
my $sth = $dbh->prepare($stmt);
$sth->execute();
my $col1;
$sth->bind_col(1,\$col1);
while ($sth->fetch) { print "$col1\n"; }
$sth->finish();
$dbh->disconnect()
;
