Oracle非法数据库对象引起错误及解决
例如:
按用户 exp 时会报错(oracle10G)
. exporting synonyms
EXP-00008: ORACLE error 3113 encountered
ORA-03113: end-of-file on communication channel
EXP-00000: Export terminated unsuccessfully
ORACLE8i 里面的的exp错误 ORA-00980。
跟踪文件里的错误:
ORA-07445: exception encountered:
core dump [joe_well_known_internal()+39] [SIGSEGV]
[Address not mapped to object] [0x1268D5C] [] []
......
SELECT SYNNAM, DBMS_JAVA.LONGNAME(SYNNAM),
DBMS_JAVA.LONGNAME(SYNTAB),TABOWN,
TABNODE, PUBLIC$, SYNOWN, SYNOWNID, TABOWNID, SYNOBJNO
FROM SYS.EXU9SYNU ORDER BY SYNTIME;
我的经验是这些数据库的用户下很可能有非法数据库对象。删除不合法的数据对象,就可以了。一般情况下生成当前用户下重编译非法数据库对象的SQL语句:
set pages 500;
set lines 200;
set trims on;
set heading off;
spool /tmp/1.sql;
select 'alter '||object_type||' '||object_name||';
compile' from user_objects where status='INVALID';
spool off;
@/tmp/1.sql;
