Workflow Save as to Database,Encounter error

Workflow Save as to Database时，报两个错误

Error1:
220: Unable to set NLS_LANGUAGE

Error2:
1004: Language is not enabled, please refers to Workflow documentation for steps on enabling a language.


原因：
环境变量NLS_LANG设置不正确，正确应为AMERICAN_AMERICA.AL32UTF8，但之前设置成了‘SIMPLIFIED CHINESE_CHINA.AL32UTF8’，

设置完之后，重启workflow builder，重新拉‘Standard’模板workflow，重新设置workflow，再save as就没问题了

注：服务器端的NLS_LANGUAGE可能和客户端查询出来的结果不一样

reference: Oracle环境变量NLS_LANG
