测试代码：
#!/usr/bin/perl -w
use DBI;
$dbname="zxsjk";
$user="rm";
$passwd="rpora";
$dbh="";
$dbh = DBI->connect("DBI:Oracle:$dbname",$user,$passwd) or die "can't connect to database ";
$sth=$dbh->prepare("select * from user_tables");
$sth->execute;
while (@recs=$sth->fetchrow_array) {
print $recs[0].":".$recs[1]."\n";
}
$dbh->disconnect;
print "hello \n";

[root@leoxqing ~]# vi /etc/profile

export TNS_ADMIN=/opt/oracle/network/admin


DBD::Oracle客户端装了，ORACLE客户端也装了,环境变量也设置了，为什么执行脚本的时候还通不过呢，很纠结，GOOGLE了N遍，没找到合适的答案，忘高手指点一下！

加了2个软链接搞定了！重新安装DBD::Oracle就搞定了！
