在新的Linux Server（Red Hat Enterprise Linux Server release 5.7 (Tikanga)）上配置磁盤空間告警的perl腳本后，測試時報如下錯誤
[oracle@DB-Server scripts]$ ./disk_capatiy_alarm.sh
Can't locate Mail/Sender.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at /home/oracle/scripts/output/disk_sendmail.pl line 2.
BEGIN failed--compilation aborted at /home/oracle/scripts/output/disk_sendmail.pl line 2.
Perl腳本disk_sendmail.pl 如下所示，其中使用了Mail-Sender郵件模塊，
1: #!/usr/bin/perl
2: use Mail::Sender;
3: $sender = new Mail::Sender {smtp => 'xxx.xxx.xxx.xxx', from => 'xxx@xxx.com'};
4: $sender->MailFile({to => 'xxx@xxx.com',
5: cc=>'xxx@xxx.com ',
6: subject => 'The server xxxx\'s Disk Capacity Alarm',
7: msg => 'Dear All,
8: The server xxxx disk capacity alarm ,please take action for it. many thanks!
9: ',
10: file => '/home/oracle/scripts/output/diskdetail.txt'});
出現這個錯誤是因為Perl沒有安裝Mail-Sender模塊，安裝了此模塊問題即可解決，Mail::Sender模塊支持發送帶附件的郵件。可以使用下面幾種方式安裝
1：使用cpan安裝，要求服務器能夠訪問外網，否則無法下載相關包。
cpan> install Mail::Sender
2：下載perl-Mail-Sender-0.8.16-1.el5.pp.noarch.rpm
下載地址：http://rpm.pbone.net/index.php3/stat/4/idpl/10370607/dir/redhat_el_5/com/perl-Mail-Sender-0.8.16-1.el5.pp.noarch.rpm.html
[root@DB-Server oracle]# rpm -ivh perl-Mail-Sender-0.8.16-1.el5.pp.noarch.rpm

3： 下載安裝Mail-Sender-0.8.16.tar.gz 。這種方法我沒有實驗過，因為http://search.cpan.org/CPAN/authors/id/J/JE/JENDA/Mail-Sender-0.8.16.tar.gz 老是無法下載這個安裝包。
