在文章《【GC】使用 agentDownload.linux完成Grid Control Agent的快速部署安裝》（http://space.itpub.net/519536/viewspace-667753）中給出了使用download方式安裝Agent的很多先決條件。本文將給大家展示一下如果沒有找到jar檔案會出現的報錯資訊。防患於未然。

1.關於環境變數PATH的正確設定
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:$PATH

其中$ORACLE_HOME/jdk/bin便是jar檔案藏身之處。為了保證Agent的順利部署，建議在環境變數在profile中提前準備好。

2.當無法找到jar檔案時的報錯資訊如下，供參考

3.問題處理
在錯誤的提示資訊中我們已經可以看到處理方法：“Add jar to your PATH and try again.”。
將jar位置新增到環境變數中，然後重新安裝即可。

4.小結
我們歡迎錯誤提示，因為錯誤資訊中充滿了指引我們前進的資訊。這些資訊可以協助我們快速解決問題。
現實情況是：很多朋友將錯誤提示作為過眼雲煙，更有可能連“過眼”的機會都不給！

Good luck.
