import导入出现ora-1013错误！
用IMPORT做数据导入时，出现如下错误信息：

IMP-00058: ORACLE error 1013 encountered
ORA-01013: user requested cancel of current operation
IMP-00058: ORACLE error 1013 encountered
ORA-01013: user requested cancel of current operation
IMP-00028: partial import of previous table rolled back: 222295 rows rolled back

不知是什么原因引起的，请大家指教！

------解决方案--------------------
ORA-01013 user requested cancel of current operation
Cause: The user interrupted an Oracle operation by entering CTRL-C, Control-C, or another canceling operation. This forces the current operation to end. This is an informational message only. 

Action: Continue with the next operation

难道是运行的半路，被谁按了CTRL+C中止了？
