ORA-01953: command no longer valid, see ALTER USER
Cause: The syntax for assigning quotas on tablespaces has changed. The ALTER USER command is now used to perform the functionality
Action: Use the alter user command instead.
ORA-01953: command no longer valid: 该错误消息表明尝试使用的命令已经不再有效,并且应该更改为替代命令。
1.检查命令并尝试更改为替代命令
2.查找文档,当可能时,了解替代命令运行方式
3.如果必须要使用ALTER USER命令,则可以运行以下命令:
ALTER USER username IDENTIFIED by password;
4.不要忘记尝试更新最新的Oracle数据库版本。
