菜鸟求教：问一个oracle exp出现的问题

mofei252

系统aix5.2 oracle 10g环境下执行exp全库备份，总是出现这个问题：

EXP-00056: ORACLE error 604 encountered
ORA-00604: error occurred at recursive SQL level 2
ORA-04031: unable to allocate 4120 bytes of shared memory ("shared pool","select /*+ rule */ bucket_cn...","Typecheck","kgghtInit")
EXP-00056: ORACLE error 604 encountered
ORA-00604: error occurred at recursive SQL level 2
ORA-04031: unable to allocate 4120 bytes of shared memory ("shared pool","select t.ts#,t.file#,t.block...","Typecheck","kgghtInit")
EXP-00000: Export terminated unsuccessfully

请大侠教我，我初用oracle，不知道怎么解决这个问题，网上搜索了很多资料，都不得要领。
