今天在给客户安装OGG的时候，EXTRACT进程无法启动。

观察日志，发现OGG-00664错误。

2013-05-08 15:07:07  ERROR   OGG-00664  OCI Error beginning session (status = 12705-ORA-12705: Cannot access NLS data files or invalid environment specified)

这个报错很明显是由于NLS_LANG环境变量设置的不对，观察EXTRACT进程配置文件，发现NLS_LANG部分用了全角的双引号。

EXTRACT extbam

SETENV (NLS_LANG=”AMERICAN_AMERICA.ZHS16GBK”)

SETENV (ORACLE_SID=yyjc1)

USERID ogguser,PASSWORD AACAAAAAAAAAAAHAVEMFFBTCODIDNHRD,ENCRYPTKEY default

DYNAMICRESOLUTION

删除双引号，问题解决。

通过观察，EXTRACT进程正常，已经这确连接2个RAC实例。
