高级复制实验配置添加复制节点操作时报错：ORA-23308: object GP.T does not exist or is invalid

出错原因：

使用高级复制时，在源端启动复制支持，执行语句：REPADMIN@bys1>execute dbms_repcat.generate_replication_support('gp','test' ,'table');

这一步时输入了错误的表名或者用户名。

错误提示：

此后，在执行在源端添加复制节点操作时，有如下出错提示：

REPADMIN@bys1>execute dbms_repcat.add_master_database(gname=>'rep',master=>'bys2' ,use_existing_objects=>true ,copy_rows=>false ,propagation_mode=>'synchronous');

BEGIN dbms_repcat.add_master_database(gname=>'rep',master=>'bys2' ,use_existing_objects=>true ,copy_rows=>false ,propagation_mode=>'synchronous'); END;

REPADMIN@bys1>select gname ,master ,status from dba_repgroup where gname = 'REP';

GNAME M STATUS

------------------------------ - ---------

REP Y QUIESCED

错误分析:

此时从dba_repobject;中可以查看到输入的有GP用户的T表，事实上是没有创建此表的。所以才会出现上面的错误：ORA-23308: object GP.T does not exist or is invalid

REPADMIN@bys1>select sname,oname,status,gname from dba_repobject;

SNAME ONAME STATUS

------------------------------ ------------------------------ ----------

GNAME

------------------------------

GP T ERROR
REP

GP TEST VALID

REP

GP TEST$RP VALID

REP

错误解决：

删除错误配置的表和用户：

REPADMIN@bys1>execute DBMS_REPCAT.DROP_MASTER_REPOBJECT (sname=>'gp',oname=>'T',type=>'TABLE');

PL/SQL procedure successfully completed.

验证：

REPADMIN@bys1>col same for a10

REPADMIN@bys1>col sname for a10

REPADMIN@bys1>col oname for a10

REPADMIN@bys1>col gname for a10

REPADMIN@bys1>select sname,oname,status,gname from dba_repobject;

SNAME      ONAME      STATUS     GNAME

---------- ---------- ---------- ----------

GP         TEST       VALID      REP

GP         TEST$RP    VALID      REP

GP         TEST$RP    VALID      REP

此时，再执行在源端添加复制节点的操作就可以顺利完成了。

REPADMIN@bys1>execute dbms_repcat.add_master_database(gname=>'rep',master=>'bys2' ,use_existing_objects=>true ,copy_rows=>false ,propagation_mode=>'synchronous');

PL/SQL procedure successfully completed.

REPADMIN@bys1>col dblink for a10
