我一直在尝试在 Centos 6.2 上安装 Oracle 11g R2 一段时间。我知道 Oracle 版本未通过 Centos 认证（但已通过 RHEL 认证），因此我根本没想到这会很简单。尽管如此，我还是设法通过修复出现的大多数问题来完成安装，但现在当我尝试运行 SQL*Plus 时，我收到了这条烦人的消息：
[oracle@centos ~]$ sqlplus
sqlplus: error while loading shared libraries: libclntsh.so.11.1: wrong ELF class: ELFCLASS64
我认为这指向一个损坏的文件，但是我已经从 Oracle 网站复制了该文件，但仍然无济于事。下面是一些有趣的结果，请注意 ldd 根本找不到这个文件，尽管它在 lib 文件夹中。
[oracle@centos ~]$ echo $LD_LIBRARY_PATH
/u01/app/oracle/product/11.2.0/dbhome_1/lib:/lib:/usr/lib </code>
[oracle@centos lib]$ ldd $ORACLE_HOME/bin/sqlplus
linux-gate.so.1 => (0x00497000)
libsqlplus.so => /u01/app/oracle/product/11.2.0/dbhome_1/lib/libsqlplus.so (0x00110000)

任何指针将不胜感激。
我还在输出下方粘贴到 id 和 env
