是SID过期了，使用此贴：https://bbs.pinggu.org/thread-6951807-1-1.html 进行SID更换，但是出现如下报错：
ERROR: User does not have appropriate authorization level for file SASHELP.CORE.CATALOG.
ERROR: The site validation data cannot be updated. This is most likely due to the fact that the
       SASHELP catalog is not available in write mode, and/or that the SETINIT option has not been
       specified when using the SAS command.
ERROR: Difficulty reading the site validation data.
NOTE: The SAS System stopped processing this step because of errors.
