1、模拟实验环境,使gc1、gc2数据不同步,对gc2上主键列作update操作

GGSCI(gc1) 7> stop RORA_1

Sending STOP request to REPLICAT RORA_1 ...

Request processed.

GGSCI(gc1) 8> info all

Program Status Group Lag Time Since Chkpt

MANAGER RUNNING

EXTRACT RUNNING EORA_1 00:00:00 00:00:01

EXTRACT RUNNING PORA_1 00:00:00 00:00:05

REPLICAT STOPPED RORA_1 00:00:00 00:00:01

gc2:

SQL>update TCUSTMER set CUST_CODE='NEW' WHERENAME='ROCKY FLYER INC.'; --gc2上updata操作

SQL>commit;

SQL>select * from TCUSTMER where CUST_CODE='NEW';

CUST_CODE NAME CITY ST

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

NEW ROCKY FLYER INC. SHANGHAI CO

gc1:

SQL>select * from TCUSTMER where CUST_CODE='NEW'; --gc1查询,没有同步更改,查询不到

no rows selected

SQL>select * from TCUSTMER where CUST_CODE='JANE'; --gc1上保留的依然是原数据

CUST_CODE NAME CITY ST

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

JANE ROCKY FLYER INC. SHANGHAI CO

2、运行veridata显示结果,如下:

--veridata捕捉到的不是update操作,而是将其拆分成了insert操作、delete操作

\

小结:

由上可知,当update主键所在的列时,veridata无法捕获出这是update操作,而是通过对比两张表,将update操作拆分成insert操作、delete操作。

3、处理同步

GGSCI(gc1) 10> start RORA_1

Sending START request to MANAGER ...

REPLICAT RORA_1 starting

GGSCI(gc1) 11> info all

EXTRACT RUNNING PORA_1 00:00:00 00:00:00

REPLICAT RUNNING RORA_1 00:12:48 00:00:02

SQL> select * from TCUSTMER where CUST_CODE='NEW';

CUST_CODE NAME CITY ST

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

NEW ROCKY FLYER INC. SHANGHAI CO
