试图打破僵局？

Question

我想替换架构....首先丢弃，然后使用impdp导入....

  SQL>drop user usertest cascade;
    ....hang no respond...

检查警报日志：

ORA-00060: Deadlock detected. More info in file /u01/app/oracle /diag/rdbms/procu/procu/trace/procu_ora_2833.trc



    Output from : /procu_ora_2833.trc

    9 : DB session is not attached to XS Session
    END OF PROCESS STATE

    *** 2015-03-02 08:53:25.276

尝试通过发出ORA-00060信号来打破僵局

请帮我解决这个问题
