场景：使用dblink加触发器同步两个库的数据，源数据库使用11g（11.2.0.1.0），目标数据库使用11g(11.2.0.1.0)。向源数据库中插入记录时，数据无法同步至目标库。并抛出ORA-03113异常。当源数据库使用12c时，一切正常，数据可能同步。
-- 创建dblink
CREATE PUBLIC DATABASE LINK datasync CONNECT TO kxmadmin IDENTIFIED BY "123456" USING '(DESCRIPTION =(ADDRESS_LIST =(ADDRESS =(PROTOCOL = TCP)(HOST = 192.168.100.92)(PORT = 1521)))(CONNECT_DATA =(SERVICE_NAME = kxm)))';
-- 创建同义词
create public synonym T_STATISTICS_ATTR_WEEK_HK for T_STATISTICS_ATTR_WEEK @DATASYNC;
-- 创建触发器
CREATE
OR REPLACE TRIGGER TEMP_trigger BEFORE INSERT ON T_STATISTICS_ATTR_WEEK FOR EACH ROW
BEGIN
IF INSERTING THEN
INSERT INTO T_STATISTICS_ATTR_WEEK_HK (
ATTR,
TIMEFLAG,
COUNT,
CREATETIME
)
VALUES
(
: NEW .ATTR,
: NEW .TIMEFLAG,
: NEW . COUNT,
: NEW .CREATETIME
) ;
END IF; END ;
