一个共享库的问题导致sqlplus用不了了的解决办法!

[root@localhost ~]# su - oracle

[oracle@localhost ~]$ sqlplus / as sysdba

sqlplus: error while loading shared libraries: /oracle/ora11gR2/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1: cannot restore segment prot after reloc: Permission denied

编辑/etc/sysconfig/selinux，找到:

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

# enforcing - SELinux security policy is enforced.

# permissive - SELinux prints warnings instead of enforcing.

# disabled - SELinux is fully disabled.

SELINUX=enforcing

如果SELINUX已经是 SELINUX=disabled，那么就不用改了，否则就把SELINUX=enforcing 注释掉，新加一行：

SELINUX=disabled

保存，退出。

如果你碰到其他类似提示：

cannot restore segment prot after reloc: Permission denied

哪应该是SELinux的问题，可以考虑把它关闭。

接下来：

[root@localhost ~]# vi /etc/selinux/config

[root@localhost ~]# su - oracle

[oracle@localhost ~]$ sqlpls / as sysdba

-bash: sqlpls: command not found

[oracle@localhost ~]$ sqlplus / as sysdba

sqlplus: error while loading shared libraries: /oracle/ora11gR2/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1: cannot restore segment prot after reloc: Permission denied

[oracle@localhost ~]$ chcon -t texrel_shlib_t /oracle/ora11gR2/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1

[oracle@localhost ~]$ sqlplus / as sysdba
