listener.ora和tnsnames.ora

关闭Agent  
编辑ORACLE_BASE/ora92/network/agent/services.ora，加上你的数据库，services.ora设为只读
启动Agent  

select * from DBA_APPLY_INSTANTIATED_OBJECTS;

no rows selected
也就是说instantiation => DBMS_STREAMS_ADM.INSTANTIATION_TABLE_NETWORK
这个操作根本没有执行到
手工实例化所有对象
在源库上取得实例化scn号:
connectSTRADMIN/STRADMIN@STREAMs
set serveroutput on
DECLARE
iscn NUMBER;
BEGIN
iscn := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
DBMS_OUTPUT.PUT_LINE ('Instantiation SCN is: ' || iscn);
END;
/
用该SCN实例化目标库上的对象
过程 SET_TABLE_INSTANTIATION_SCN控制表的哪些LCRs将被应用进程应用。
如果源库上LCRs的提交scn小于等于实例化的scn，则应用进程丢弃该LCR，否则应用进程应用该scn。

connectSTRADMIN/STRADMIN@streamd
BEGIN
DBMS_APPLY_ADM.SET_TABLE_INSTANTIATION_SCN(
source_object_name => 'TEST.EMP',
source_database_name =>' STREAM',
instantiation_scn => 18902052364 );
END;

DBMS_APPLY_ADM.SET_SCHEMA_INSTANTIATION_SCN('TEST','STREAM', 18902294194 );

ORA-01031:insufficient privileges; 无此权限

select dbms_flashback.get_system_change_number from dual;取得scn

检查一下source database的global name和db link的名字,如果是一样的那我也不知道为什么了.

strmadmin@ICWEB> select owner, db_link from dba_db_links;

OWNER DB_LINK

---------------------------------- -------------------------------------------
STRMADMIN OPDB.xxxxxxx.COM

strmadmin@OPDB> select * from global_name;

GLOBAL_NAME
--------------------------------------------------------
OPDB.xxxxxxx.COM

Set the SCN by calling DBMS_APPLY_ADM.SET_INSTANTIATION_SCN

源数据库上执行
DECLARE
  iscn  NUMBER;
BEGIN
  iscn := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
DBMS_APPLY_ADM.SET_SCHEMA_INSTANTIATION_SCN@zhj151(
  source_schema_name => 'scott.st',
  source_database_name => 'ora2.utrust.com',
  instantiation_scn => iscn,
  recursive  => true);
END;
