今天修改了一個參數 NLS_LANG? 導致數據庫報錯。
ORA-12705: 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.

后來只能又把參數改了回來。如果我想改參數而又不報錯，改怎么辦呢？
