ORA-12705: Cannot access NLS data files or invalid environment specified，ora-12705nls

ORA-12705: Cannot access NLS data files or invalid environment specified，ora-12705nls
如果是因為配置oracle用戶端引起的事故，就嘗試著吧環境變數中的NLS_LANG直接刪除即可的。
linux下安裝orcal出現ORA-12705: Cannot access NLS data files or invalid environment specified 錯誤

串連oracle資料庫時出現了如下錯誤：
問題解決：eclipse的環境編碼和oracle有衝突
oracle在註冊表中NLS_LANG值為SIMPLIFIED CHINESE_CHINA.ZHS16GBK
eclipse啟動時的設定檔eclipse.ini的-Duser.language屬性卻為en
將en改為zh，問題解決。
希望對你有所協助！
 
oracle ORA-12705: Cannot access NLS data files or invalid environment specified

2705, 00000, "Cannot access NLS data files or invalid environment specified"
// *Cause: Either an attempt was made to issue an ALTER SESSION command
// with an invalid NLS parameter or value; or the environment
// variable(s) NLS_LANG, ORA_NLSxx, or ORACLE_HOME was incorrectly
// specified, therefore the NLS data files cannot be located.
// *Action: Check the syntax of the ALTER SESSION command and the NLS
// parameter, correct the syntax and retry the statement, or
// specify the correct directory path/values in the environment
// variables.

檢查一下你的參數檔案是不是有問題
