LIUNX下Oracle9.2怎么不能备份,哥哥们救命呀。

小弟对LIUNX还不熟
费劲千心万苦才装上Oracle9.2
用imp 没有问题,可用exp 备份 就不行了。总是出下面的提示

. exporting pre-schema procedural objects and actions
. exporting foreign function library names for user TELCOM
. exporting PUBLIC type synonyms
. exporting private type synonyms
. exporting object type definitions for user TELCOM
EXP-00008: ORACLE error 942 encountered
ORA-00942: table or view does not exist
EXP-00024: Export views not installed, please notify your DBA
EXP-00000: Export terminated unsuccessfully

不知道是不是要打补丁呀
那位高手帮帮忙吧
