Drop goldengate用户时报ORA-00604 ORA-20782 ORA-06512问题解决

1、问题现象

SQL> drop user goldengate cascade;

  Drop goldengate用户时，报ORA-00604 ORA-20782 ORA-06512错误，具体报错内容如下：

drop user goldengate cascade * ERROR at line 1: ORA-00604: error occurred at recursive SQL level 2 ORA-20782: Oracle GoldenGate DDL Replication Error: Code :ORA-20782: Cannot DROP object used in Oracle GoldenGate replication while trigger is enabled. Consult Oracle GoldenGate documentation and/or call Oracle GoldenGate Technical Support if you wish to do so., error stack: ORA-06512: at line 261 ORA-06512: at line 1111

2、原因分析

        由于在安装OGG时，配置并开启了DDL捕获功能，而OGG的DDL捕获，是依赖DDL触发器实现的，DDL处于enabled状态，drop goldengate user操作也属于DDL操作，所以产生ORA-00604 ORA-20782错误

3、验证DDL触发器状态

SQL> set linesize 999

SQL>select owner,trigger_name,trigger_type,triggering_event,status from dba_triggers where trigger_name like 'GGS%';

OWNER      TRIGGER_NAME          TRIGGER_TYPE     TRIGGERING_EVENT   STATUS -----------------  ---------------------------      -----------------------   -----------------------------   --------- SYS         GGS_DDL_TRIGGER_BEFORE   BEFORE EVENT    DDL             ENABLED

4、删除触发器

SQL>drop trigger sys.GGS_DDL_TRIGGER_BEFORE

5、再次尝试删除用户

SQL> drop user goldengate cascade;

drop user goldengate cascade * ERROR at line 1: ORA-00604: error occurred at recursive SQL level 1 ORA-14452: attempt to create, alter or drop an index on temporary table already in use

    再次报错，但是报错内容发生了改变

    报错意思为：试图创建，更改或删除正在使用的临时表中的索引

6、找出正在使用临时表的会话，并killsession

SQL>select 
'alter system kill session '''||sid||','||serial#||'''' from
v$session where sid
in
(select sid 
from v$lock where id1
in
(select object_id from dba_objects
where object_name in
(select table_name from dba_tables
where owner='GOLDENGATE')));

7、再次删除用户

SQL> drop user goldengate cascade;

User dropped.

 

删除成功。
