[oracle@Database-backup ~]$ sqlplus / as sysdba
sqlplus: error while loading shared libraries: libclntsh.so.11.1: cannot open shared object file: No such file or directory
[oracle@Database-backup lib]$ ls libclntsh.so*
libclntsh.so libclntsh.so.10.1 -->只有10.1 cp -rp 连带属性完全复制一份，正常若有libclntsh.so.11.1文件可能是权限问题。
[oracle@Database-backup lib]$ cp -rp libclntsh.so.10.1 libclntsh.so.11.1
[oracle@Database-backup lib]$ sqlplus / as sysdba
... 正常.
