各位大虾:
我在linux下导出oracle,oracle字符集ZHS32GB18030,linux NLS_LANG为SIMPLIFIED CHINESE_CHINA.ZHS32GB18030,切换至oracle用户后,exp user/psd file=./asb.dmp
可是运行到 exporting PUBLIC type synonyms 时就停止了,隔了一段时间后提示
EXP-00008: ORACLE error 4021 encountered
ORA-04021: timeout occurred while waiting to lock object
EXP-00000: Export terminated unsuccessfully
请问是什么原因?
搞了1天也没有解决,很郁闷阿...
谢谢先

Cause: While waiting to lock a library object, a timeout is occurred.
Action: Retry the operation later
可以查一下你的log日志文件,看是哪里出了问题
update props$
set value$='US7ASCII'
where name='NLS_CHARACTERSET';
