在部署goldengate过程中发现如下错误：
[oracle@localhost OGG]$ ggsci
ggsci: error while loading shared libraries: /opt/oracle/product/10.2.0/db_1/lib/libclntsh.so.10.1: cannot restore segment prot after reloc: Permission denied
查找资料，没有专门说ogg安装这个错误，是SELinux启用导致，但是有很多其他程序执行过程中报类此错误是有此导致，那么我抱着尝试的态度实验看看：
1、查看SELinux是否被关闭
[oracle@localhost tmp]$ more /etc/selinux/config
# 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=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted – Only targeted network daemons are protected.
# strict – Full SELinux protection.
SELINUXTYPE=targeted
说明已经关闭。那就奇怪了，既然已经闭关了那为什么还不行？于是我怀疑，是不是有人只是修改了SELINUX=disabled，没有重启系统或者使用命令使其生效导致。
2、查看SELINUX修改是否生效
[root@localhost ~]# getenforce
Enforcing
果然修改没有生效
3、使SELINUX生效
[root@localhost ~]# setenforce 0
再次查询，现在已经生效
[root@localhost ~]# getenforce
Permissive
4、然后启动ggsci
[oracle@localhost ~]$ ggsci
