  GG配置Oracle同步到SQLServer

  源端目标端准备一张测试用的表。 Oracle源端: drop table ggmgr.t1; create table ggmgr.t1( id int primary key, name varchar2(50), time date);

  Sqlserver目标端: BEGIN TRANSACTION SET QUOTED_IDENTIFIER ON SET ARITHABORT ON SET NUMERIC_ROUNDABORT OFF SET CONCAT_NULL_YIELDS_NULL ON SET ANSI_NULLS ON SET ANSI_PADDING ON SET ANSI_WARNINGS ON COMMIT BEGIN TRANSACTION GO CREATE TABLE dbo.Table_1 ( id numeric(18, 0) NOT NULL, name nvarchar(40) NULL, time date NULL ) ON [PRIMARY] GO ALTER TABLE dbo.Table_1 ADD CONSTRAINT PK_Table_1 PRIMARY KEY CLUSTERED ( id ) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO ALTER TABLE dbo.Table_1 SET (LOCK_ESCALATION = TABLE) GO COMMIT

  在线持续同步表

  Oracle端(配置extract进程) dblogin userid ggmgr,password oracle add trandata test.n

  edit param e_erp extract e_erp userid ggmgr,password oracle setenv(ORACLE_SID=orcl) exttrail ./dirdat/dd table ggmgr.t1;

  添加extract进程 add extract e_erp,tranlog,begin now 创建本地trail文件(并不是物理上真的创建),这个e_erp要之前就按这个名称添加了extract进程。 add exttrail ./dirdat/dd, extract e_erp

  配置data pump进程 edit params d_erp extract d_erp userid ggmgr,password oracle rmthost 10.60.17.48,mgrport 7809 rmttrail D:\gg\dirdat\dd table ggmgr.t1;

  add extract d_erp, exttrailsource /home/ora/gg/dirdat/dd add rmttrail D:\gg\dirdat\dd, extract d_erp

  sqlserver端(配置replicat进程)

  传送defgen工具定义文件

  在SQLServe目标端,配置globals文件,指定用某个checkpoint表 /ggsci edit params ./GLOBALS CHECKPOINTTABLE MASTER.DBO.GG_CHECKPOINT_TAB

  globals文件必须在在$GGS_HOME目录下,即软件根目录下,如果已经存在一个,可以先move走它。

  为目标端配置checkpoint table dblogin sourcedb mssql(这个名称,是我们定义在ODBC数据源的那个代表某给sqlserver服务的描述符) add checkpointtable master.dbo.gg_checkpoint_tab

  配置replicat进程 EDIT PARAMS R_ERP replicat r_erp sourcedb mssql sourcedefs D:\gg\dirdef\defgen.def reperror default,discard discardfile ./dirrpt/r_erp.dsc,append,megabytes 50 map ggmgr.t1, target fwy.dbo.t1;

  discardfile参数推荐用这个参数,对于数据库拒绝的数据,会反映到这个文件中

  增加replicat进程 add replicat r_erp, exttrail D:\gg\dirdat\dd

  然后用defgen工具,将表定义传送到目标端

  源端跑起来 start e_bom start d_bom 目标端 start replicat r_bom view report r_erp

  如果想过滤某些列,什么都不用做。例如源端有7个字段,目标端有6个,同名字段自动匹配,没的会自动去掉。但如果字段名有些一样,有些不同呢? map ggmgr.t3, target fwy.dbo.t3, colmap ( usedefaults, --意味着字段名相同就用默认的复制 target_col = source_col); --目标表字段名是target_col,从源端的字段名是source_col的字段处抽取。
