Oracle 11g安装报错cannot restore segment prot after reloc: Permission denied
[日期：2012-07-28] 来源：Linux社区 作者：mfkqwyc86
环境：
RedHat Linux AS5.7 +Oracle11.2.0.1 X86_64位环境
安装完Oracle11.2.0.1后，通过netca创建监听程序，然后执行lsnrctl status，报错如下：
[Oracle @bt bin]#lsnrctl status
./lsnrctl: error while loading shared libraries: /Oracle/ora11g/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1: cannot restore segment prot after reloc: Permission denied-
解决过程如下：
[root@bt bin]#semanage fcontext -a -t textrel_shlib_t /Oracle/ora11g/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1
csvn homedir /opt/CollabNet_Subversion or its parent directory conflicts with a defined context in /etc/selinux/targeted/contexts/files/file_contexts, /usr/sbin/genhomedircon will not create a new context. This usually indicates an incorrectly defined system account. If it is a system account please make sure its login shell is /sbin/nologin.
[root@bt bin]# restorecon -R -v /Oracle/ora11g/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1
restorecon reset /home/mnum/app/mnum/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1 context user_u:object_r:user_home_t:s0->system_u:object_r:textrel_shlib_t:s0
重新执行lsnrctl status，问题解决。
