求助：Redhat 4_64-bit下安装oracle 11g出现如下错误

虚拟机下的RedHat 4 安装oracle 11g,检查配置时都是passed，但不知为何会出现如下（日志文件）错误：
我不清楚是不是我设置ip的问题，虚拟机下用的是NAT上网方式（桥接方式无法dhcp自动获得ip），Redhat内部用dhcp或是静态IP都试过去安装，似乎都不行

out文件中：

Configuration assistant "Oracle Net Configuration Assistant" failed

Not successfully running any "Recommended" assistants means your system will not be correctly configured. Select the failed assistants and click the 'Retry' button to retry them.

err文件中的提示如下：
java.lang.UnsatisfiedLinkError: jniGetOracleHome
at oracle.net.common.NetGetEnv.jniGetOracleHome(Native Method)
at oracle.net.common.NetGetEnv.getOracleHome(Unknown Source)

Oracle Net Services configuration failed. The exit code is -1

另外，输入 sqlplus /nolog会提示：
sqlplus: error while loading shared libraries: libsqlplus.so: cannot open shared object file :No such file or directory

因为你设置的是DHCP。所以你应该设置ORACLE_HOSTNAME环境变量。
