毛毛的小窩 — 關(guān)注技術(shù)交流、讓我們一起成長

今天修改了一個參數(shù) NLS_LANG  導(dǎo)致數(shù)據(jù)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(shù)改了回來。如果我想改參數(shù)而又不報錯，改怎么辦呢？
