配置ogg异构oracle-mysql（3）目的端配置

gtxyzz 首页 2023-02-27 1075浏览 0

目的端配置大致分为如下三个步骤：配置mgr，配置checkpoint table，配置应用进程

在目的端先创建一张表，记得带主键：

mysql> create database hr;
Query OK, 1 row affected (0.00 sec)

mysql> use hr
Database changed
mysql> create table ah4(id int ,name varchar(10),primary key(id));
Query OK, 0 rows affected (0.00 sec)

mysql> show tables;
+————–+
| Tables_in_hr |
+————–+
| ah4 |
+————–+
1 row in set (0.00 sec)

mysql>

1.配置mgr

GGSCI (nosql2) 2> edit params mgr

PORT 7809
DYNAMICPORTLIST 7810-7909
--AUTOSTART ER *
AUTORESTART EXTRACT *,RETRIES 5,WAITMINUTES 3
PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3
LAGREPORTHOURS 1
LAGINFOMINUTES 30
LAGCRITICALMINUTES 45


GGSCI (nosql2) 3> start mgr

Manager started.

GGSCI (nosql2) 4> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING

2.配置checkpoint table

GGSCI (nosql2) 7> edit  params ./GLOBALS

CHECKPOINTTABLE hr.checkpoint

添加：

GGSCI (nosql2) 8>  add checkpointtable hr.checkpointtab

Successfully created checkpoint table hr.checkpointtab.

GGSCI (nosql2) 9> info checkpointtable hr.checkpointtab

Checkpoint table hr.checkpointtab created 2014-04-02 16:11:38.

GGSCI (nosql2) 10> 


在相应的mysql数据库中，也可以看到相应的表被添加了：
mysql> show tables;
+---------------+
| Tables_in_hr  |
+---------------+
| ah4           |
| checkpointtab |
+---------------+
2 rows in set (0.00 sec)

3.配置应用进程：

GGSCI (nosql2) 10> edit params rep3 

replicat rep3
sourcedefs /u01/ogg/11.2/dirdef/ah4.prm
SOURCEDB hr,userid root,password 123456
reperror default,discard
discardfile /u01/ogg/11.2/dirrpt/rep4.dsc,append,megabytes 50
map hr.ah4, target hr.ah4;

GGSCI (nosql2) 13> add replicat rep3,exttrail /u01/ogg/11.2/dirdat/xs,checkpointtable hr.checkpointtab
REPLICAT added.

PS:

REPLICAT进程参数配置说明：
ASSUMETARGETDEFS：假定两端数据结构一致使用此参数；
SOURCEDEFS：假定两端数据结构不一致，使用此参数指定源端的数据结构定义文件，该文件需要由GlodenGate工具产生。
MAP:用于指定源端与目标端表的映射关系；
MAPEXCLUDE：用于使用在MAP中使用*匹配时排除掉指定的表；
REPERROR：定义出错以后进程的响应，一般可以定义为两种：
ABEND，即一旦出现错误即停止复制，此为缺省配置；
DISCARD，出现错误后继续复制，只是把错误的数据放到discard文件中。
DISCARDFILE：定义discardfile文件位置，如果处理中油记录出错会写入到此文件中；
SQLEXEC：在进程运行时首先运行一个SQL语句；
GROUPTRANSOPS：将小交易合并成一个大的交易进行提交，减少提交次数，降低系统IO消耗。
MAXTRANSOPS：将大交易拆分，每XX条记录提交一次。

4.测试

在目的端启动rep3进程，在源端启动ext3和push3进程。

在源端的ah4表中插入一条数据，看是否在目的端的ah4表中能看到。

源端进程：

GGSCI (ora11g) 30> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING                                           
EXTRACT     RUNNING     EXT1        00:00:00      00:00:03    
EXTRACT     RUNNING     EXT2        00:00:00      00:00:07    
EXTRACT     RUNNING     EXT3        00:44:09      00:00:06    
EXTRACT     RUNNING     PUSH1       00:00:00      00:00:03    
EXTRACT     RUNNING     PUSH2       00:00:00      00:00:03    
EXTRACT     RUNNING     PUSH3       00:00:00      00:37:40    

GGSCI (ora11g) 31>

源端插入数据：

SQL> insert into ah4 values(1,'aaaccc');

1 row created.

SQL> commit;

Commit complete.
