exp数据出不来

sigin

我有一台服务器，装的还是很老的ORACLE7.3.4,最近在做EXP数据导出时，发现不能成功，提示如下：
Connected to: Oracle7 Server Release 7.3.4.0.0 - Production
With the distributed, replication and parallel query options
PL/SQL Release 2.3.4.0.0 - Production
Export done in ZHS16CGB231280 character set
Note: table data (rows) will not be exported

EXP-00008: ORACLE error 1089 encountered

ORA-06512: at "SYS.DBMS_JOB", line 230
ORA-06512: at line 1
EXP-00000: Export terminated unsuccessfully
用system用户导这个用户的数据也不行，数据库关闭或开启都是正常的，没有错误提示，请问是哪儿出问题了呢，谢谢

建议帖子alter.log日志上来看看.

一直停在这儿，再也下不进了，只能杀进程才能退出来，退出后select * from dba_sequences也半天出不来，查看alter日志，出现600代Fri Feb  9 10:01:22 2007

要从何查起呢，郁
