1.安裝instantclient的相關包：
instantclient-basic-linux-x86-64-11.2.0.2.0.zip 基礎包
instantclient-sdk-linux-x86-64-11.2.0.2.0.zip 使用c或perl連接db
instantclient-sqlplus-linux-x86-64-11.2.0.2.0.zip sqlplus
2.設置環境變量
export PATH=/home/loganalysis/perlM/instantclient/instantclient_11_2:$PATH
export ORACLE_HOME=/home/loganalysis/perlM/instantclient/instantclient_11_2
export LD_LIBRARY_PATH=/home/loganalysis/perlM/instantclient/instantclient_11_2
export SQLPATH=/home/loganalysis/perlM/instantclient/instantclient_11_2:${SQLPATH}
export TNS_ADMIN=/home/loganalysis/perlM/instantclient/instantclient_11_2:${TNS_ADMIN}
3.復制tnsnames.ora至/home/loganalysis/perlM/instantclient/instantclient_11_2
開始測試。
#!/usr/bin/perl
use DBI;
$dbname="bossdata";
$user="system";
$passwd="javama";
$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";
//測試通過。
