我已经安装了以下Oracle Instant Client rpm：

oracle-instantclient11.2-basic-11.2.0.2.0.x86_64.rpm
oracle-instantclient11.2-devel-11.2.0.2.0.x86_64.rpm
oracle-instantclient11.2-sqlplus-11.2.0.2.0.x86_64.rpm

并将以下变量添加到我的.bash_profile：

export TNS_ADMIN=/etc
export ORACLE_HOME=/usr/lib/oracle/11.2
export LD_LIBRARY_PATH=$ORACLE_HOME/client64/lib
PATH=$PATH:$HOME/bin:/sbin:$ORACLE_HOME/client64/bin

在文件/etc/tnsnames.ora中,我编写了从运行Oracle数据库的远程站点的同事那里收到的信息：

some_string =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = my_address)(PORT = my_port))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = PDTT)
    )
  )

好的部分是我现在可以通过运行从CLI连接

sqlplus 'my_user/my_password@//my_address:my_port/PDTT'

然后通过发出可以看到一些表格：

select table_name from user_tables;

而且我也成功运行了sudo pecl install oci8,添加了文件/etc/PHP.d/oci8.ini,其中包含：

extension=oci8.so

并且可以看到以下PHPinfo()输出

现在我的问题和问题请：

1)如何设置ORACLE_SID变量以及如何在设置后调用sqlplus？可以/我应该使用PHP和Perl脚本中的ORACLE_SID吗？

2)我运行sudo -E perl -MCPAN -e shell,它在安装其他Perl模块时运行良好,但对于“install DBD :: Oracle”,它失败了：

CPAN.pm: Going to build T/TI/TIMB/DBD-Oracle-1.26.tar.gz

Using DBI 1.52 (for perl 5.008008 on x86_64-linux-thread-multi) installed in /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/auto/DBI/

Configuring DBD::Oracle for perl 5.008008 on linux (x86_64-linux-thread-multi)

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

  The ORACLE_HOME environment variable value (/usr/lib/oracle/11.2) is not valid.
  It must be set to hold the path to an Oracle installation directory
  on this machine (or a machine with a compatible architecture).
  For an Instant Client install,the directory should include an sdk subdirectory.
  See the appropriate README file for your OS for more information.
  ABORTED!
Running make test
  Make had some problems,maybe interrupted? Won't test
Running make install
  Make had some problems,maybe interrupted? Won't install

它提到上面的“sdk”目录,但转速根本没有那个目录：

# rpm -ql oracle-instantclient11.2-devel | grep -i sdk
#

感谢您提供有关Oracle安装和使用的任何提示和任何有用的提示.有很多Oracle信息,但它通常假设Oracle安装在同一台机器上.
