perl 连接oracle

1.运行时报错
db.pl

[root@localhost ~]# db.pl

2。

[root@localhost DBD-Oracle-1.22]# perl Makefile.PL
Using DBI 1.611 (for perl 5.008008 on i386-linux-thread-multi) installed in /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/auto/DBI/

Configuring DBD::Oracle for perl 5.008008 on linux (i386-linux-thread-multi)

Remember to actually *READ* the README file! Especially if you have any problems.

Installing on a linux, Ver#2.6
Using Oracle in /tmp/instantclient_10_2
sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file: No such file or directory

            If sqlplus failed due to a linker/symbol/relocation/library error or similar problem
            then it's likely that you've not configured your environment correctly.
            Specifically, your LD_LIBRARY_PATH environment variable
            set to include the directory containing the Oracle libraries.

I'm having trouble finding your Oracle version number... trying harder

WARNING: I could not determine Oracle client version so I'll just
default to version 8.0.0.0. Some features of DBD::Oracle may not work.
Oracle version based logic in Makefile.PL may produce erroneous results.
