A user complains that he gets the following error message repeatedly after executing some SQL statements. The error message forces the user to log off from and log on to the database to continue his work. ORA-02392: exceeded session limit on CPU usage, you are being logged off Which action would you take to increase the session limit on CPU usage? A) Modify the profile assigned to the user. B) Modify the roles assigned to the users. C) Modify the object privileges assigned to the user. D) Modify the system privileges assigned to the users. E) Modify the value for the RESOURCE_LIMIT parameter in the parameter file.
Answer: A Oracle系统中的profile可以用来对用户所能使用的数据库资源进行限制,使用Create Profile命令创建一个Profile,用它来实现对数据库资源的限制使用,如果把该profile分配给用户,则该用户所能使用的数据库资源都在该profile的限制之内。 profile分两部分,RESOURCE_LIMIT为true限定 资源参数(resource parameters) 设置有效,密码参数(password parameters)设置始终有效,不管RESOURCE_LIMIT的值为true或false.
