  • cannot restore segment prot after reloc: Permission denied

    在power5 Linux上安装oracle10g后,通过命令行方式登录sqlplus时,报错:

    error while loading shared libraries: $ORACLE_HOME/lib/libnnz10.so: cannot restore segment prot after reloc: Permission denied

    最后的Permission denied显示,初步认为是系统安全屏蔽了oracle执行某些执行动作。于是检查系统防火墙iptables,已经关闭,于是想到了Selinux

    [root@localhost ~]# more /etc/sysconfig/selinux

    # 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

    # SELINUXTYPE= type of policy in use. Possible values are:

    # targeted - Only targeted network daemons are protected.

    # strict - Full SELinux protection.

    SELINUXTYPE=targeted

    看来是selinux的缘故,关掉selinux试试!

    修改SELINUX=disabled,然后重启系统才能生效,或者执行:setenforce 0,立即生效。

    果然,关闭selinux后,sqlplus可以正常登陆了。

    其实在上面出现Permission denied时,也可以执行

    #chcon -t texrel_shlib_t $ORACLE_HOME/lib/*.so

    问题也可以得到解决,至于chcon可以看看selinux方面的命令即可明白了!
