故障分析:ORA-00904:invalid column name

今天在用户现场接触一个8i的数据库，好久未接触，差点就忘了SVRMGRL工具了。

客户数据库在导出时一直存在一个错误，问题出现在导出同义词阶段：

. exporting synonyms
EXP-00008: ORACLE error 904 encountered
ORA-00904: invalid column name
EXP-00000: Export terminated unsuccessfully

使用DBMS_SYSTEM跟踪一下导出，发现最后出错停留在以下SQL上：

SELECT SYNNAM, DBMS_JAVA.LONGNAME(SYNNAM), DBMS_JAVA.LONGNAME(SYNTAB), TABOWN, TABNODE, PUBLIC$, SYNOWN, SYNOWNID  FROM SYS.EXU8SYN WHERE SYNOWNID=:1 ORDER BY SYNTIME

手工执行这个脚本出现同样的错误：

SQL> SELECT SYNNAM,
  2         DBMS_JAVA.LONGNAME(SYNNAM),
  3         DBMS_JAVA.LONGNAME(SYNTAB),
  4         TABOWN,
  5         TABNODE,
  6         PUBLIC$,
  7         SYNOWN,
  8         SYNOWNID
  9    FROM SYS.EXU8SYN
 10  /
 
SELECT SYNNAM,
       DBMS_JAVA.LONGNAME(SYNNAM),
       DBMS_JAVA.LONGNAME(SYNTAB),
       TABOWN,
       TABNODE,
       PUBLIC$,
       SYNOWN,
       SYNOWNID
  FROM SYS.EXU8SYN
 
ORA-00904: invalid column name

发现又是java对象的问题：

SQL> select owner, status, object_type, object_name from all_objects
  2  where object_name like'%DBMS_JAVA%';
 
OWNER                          STATUS  OBJECT_TYPE        OBJECT_NAME
------------------------------ ------- ------------------ ------------------------------
SYS                            VALID   PACKAGE            DBMS_JAVA_TEST
SYS                            VALID   PACKAGE BODY       DBMS_JAVA_TEST
PUBLIC                         VALID   SYNONYM            DBMS_JAVA_TEST

Metalink上可以找到大量相关的文档记录，解决方案是，要么完全无误的安装JAVA对象，要么彻底移除,移除可以运行rmjvm.sql脚本,该脚本位于$ORACLE_HOME/javavm/install/rmjvm.sql
If Java is enabled, ensure that both DBMS_JAVA synonyms and packages are created and valid.
The following script can be used to create the required packages,
"$ORACLE_HOME/javavm/install/initdbj.sql". This will need to be run as SYSDBA.

If Java is disabled, run "$ORACLE_HOME/javavm/install/rmjvm.sql" to remove Java related
objects. Do not just drop the synonym.
记录一下备查。
