【GC】无法找到jar命令导致Download方式安装Agent失败的处理

在文章《【GC】使用 agentDownload.linux完成Grid Control Agent的快速部署安装》（http://space.itpub.net/519536/viewspace-667753）中给出了使用download方式安装Agent的很多先决条件。本文将给大家展示一下如果没有找到jar文件会出现的报错信息。防患于未然。

1.关于环境变量PATH的正确设置
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:$PATH

其中$ORACLE_HOME/jdk/bin便是jar文件藏身之处。为了保证Agent的顺利部署，建议在环境变量在profile中提前准备好。

2.当无法找到jar文件时的报错信息如下，供参考

将jar位置添加到环境变量中，然后重新安装即可。

4.小结
我们欢迎错误提示，因为错误信息中充满了指引我们前进的信息。这些信息可以协助我们快速解决问题。
现实情况是：很多朋友将错误提示作为过眼云烟，更有可能连“过眼”的机会都不给！

Good luck.
