【OGG】GoldenGate For Oracle实施文档 --超详细总结版

Oracle to Oracle版本的

平时给客户生产环境部署参考的文档,总结的比较详细,主要是详细的说明了数据初始化的过程,参数各个环境不同,所以只是写了比较简单的,根据实际条件添加吧。

1. 前期准备

1.1. 系统层面

windows需要安装c\c++ 2005运行库

1.2. 数据库层面

运行full-DB_CheckOracle.sql 查看结果,检查是否有不支持的对象

2. 源端数据库配置

2.1. 开启归档模式

检查源端数据库是否为归档模式

SQL>archive log list;

若为非归档模式,在数据库mount状态下将其改为归档模式

SQL> alter database archivelog;

确认归档已经开启

SQL>archive log list;

2.2. 开启库级别最小附加日志

检查源端数据库附加日志是否打开

SQL>select supplemental_log_data_min from v$database;

打开数据库附件日志

SQL>alter database add supplemental log data;

切换日志以使附加日志生效

SQL>ALTER SYSTEM ARCHIVE LOG CURRENT;

SQL>alter system switch logfile;

确认最小附加日志已经打开

select supplemental_log_data_min from v$database;

2.3. 创建GoldenGate专有用户

创建goldengate表空间:

SQL>create tablespace goldengate datafile '/oracle/oracle/oradata/ora11/goldengate.dbf' size 100m;

注:不开启DDL的话源端goldengate不会在数据库中创建任何表,存储任何数据,所以这个表空间给较少空间即可

创建goldengate用户并授权:

SQL>create user goldengate identified by goldengate default tablespace goldengate;

给用户授权:

如果客户对于权限管理不严格,直接赋予DBA权限即可:

SQL>grant dba to goldengate;

如果管理严格请参考各版本OGG文档进行授权

注:如开启DDL必须需要DBA权限

3. 源端部署GoldenGate

3.1. 下载并将GoldenGate上传到服务器

Linux\Unix传到Oracle用户即可,windows传到Oracle的安装用户下

3.2. 配置环境变量

主要配置以下三个变量:

ORACLE_SID         ORACLE_HOME       LD_LIBRARY_PATHLINUX环境)

其中D_LIBRARY_PATHogg的安装目录

export LD_LIBRARY_PATH=/ggs/11.0:$LD_LIBRARY_PATH

3.3. 配置启动mgr

windows环境需要加入到服务中

.\install addservice

 

 

./ggsci

create subdirs

 

配置mgr参数

edit params mgr

port 7809

DYNAMICPORTLIST 7840-7898

autostart er *

autorestart er *, retries 5, waitminutes 3

PURGEOLDEXTRACTS ./dirdat/*,USECHECKPOINTS, MINKEEPDAYS 7

启动mgr

start mgr

确认mgr启动成功

info all

3.4. 增加trandata

ggsci登录到数据库

dblogin userid goldengate,password goldengate

增加trandata

add TRANDATA ajdbo.passenger

确认trandata添加成功

info trandata ajdbo.passenger

在数据库中确认已经添加trandata的表

select * from dba_log_groups where owner='xxx' and table_name='xxx';

3.5. 配置、启动extract进程

增加extract进程

add extract ext_ynkg, tranlog, begin now

增加exttrail

add exttrail ./dirdat/ld,extract ext_ynkg, MEGABYTES 100

配置extract进程

edit params ext_ynkg

 

EXTRACT ext_ynkg

SETENV(NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

USERID goldengate, PASSWORD goldengate  

TRANLOGOPTIONS EXCLUDEUSER goldengate

EXTTRAIL ./dirdat/ld

--GETTRUNCATES

--GETUPDATEBEFORES

EOFDELAY 3

NUMFILES 5000

DISCARDFILE ./dirrpt/ext_ynkg.dsc, APPEND, MEGABYTES 1000

DYNAMICRESOLUTION

table ajdbo.passenger;

talle ajdbo.channel;

table ajdbo.validate_info;

table ajdbo.bord_info;

启动extract进程

start ext_ynkg

确认进程启动成功

info ext_ynkg

3.6. 获取基准SCN

3.6.1. 方法一

如果客户环境归档保留的比较多,则可采用这种方法:

首先确认系统中最早的transaction的启动时间

sql> select min(start_time) from gv$transaction;

MIN(START_TIME)

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

02/08/16 19:21:38

之后在指定extract进程的begin时间时,指定一个比这个早的时间,让extract从这里开始抽取:

add extract <ext_name> tranlog threads 2 begin 2016-02-08 19:20:00

最后再查询当前SCN

select current_scn from v$database;

则该SCN则为基准SCNSCN3),如使用导入导出的方法,这个SCN即为最终确定的SCN时间点,如果使用RMAN则最终RMAN恢复的SCN要大于等于这个SCN

3.6.2. 方法二

如果客户环境归档保留的比较少,则可采用这种方法

查询当前SCN号(SCN1

select current_scn from v$database;

查看当前数据库系统中最早transactionscn号(SCN2

select min(start_scn) from gv$transaction;

多次查询系统中最早的transaction的启动时间,一直到这个值大于SCN1。(如果大的transaction一直在运行,可以考虑杀死这个transaction对应的进程,查找该进程的语句如下:

select p.INST_ID,p.SPID,t.start_scn

from gv$transaction t,gv$process p,gv$session s

where s.taddr=t.addr and p.addr=s.paddr and t.start_scn<=&1;

再次查询当前SCN号(SCN3

select current_scn from v$database;

则该SCN则为基准SCNSCN3),如使用导入导出的方法,这个SCN即为最终确定的SCN时间点,如果使用RMAN则最终RMAN恢复的SCN要大于等于这个SCN

3.7. 归档当前日志(可选)

这一步仅当使用RMAN做初始化并使用的是之前的全备时需要,是为了拷贝过去的归档能恢复到之前确定的SCN

 

查询当前日志号:

select INST_ID,GROUP#,SEQUENCE#,ARCHIVED,STATUS from gv$log;

归档当前日志:

ALTER SYSTEM ARCHIVE LOG CURRENT;

之后确认第一次为currentSEQUENCE已经归档

select INST_ID,SEQUENCE#,ARCHIVED from gv$archived_log where SEQUENCE#=&1;

注:RAC环境下两个节点都要进行确认

3.8. 配置pump进程

增加pump进程

add extract pmp_ynkg, exttrailsource ./dirdat/ld

增加rmttail文件

add rmttrail ./dirdat/rd,EXTRACT pmp_ynkg,MEGABYTES 100

配置pump进程

edit params pmp_ynkg

 

EXTRACT  pmp_ynkg

USERID goldengate,PASSWORD goldengate

PASSTHRU

RMTHOST 10.1.0.50,MGRPORT 7809

RMTTRAIL ./dirdat/rd

--REPORT AT 01:59

--REPORTROLLOVER AT 02:00

DISCARDFILE ./dirrpt/pmp_ynkg.dsc, APPEND, MEGABYTES 1000

--PURGEOLDEXTRACTS ./dirdat/*,USECHECKPOINTS, MINKEEPDAYS 7

DYNAMICRESOLUTION

table ajdbo.*;

4. 数据初始化

4.1. 导入导出方式

4.1.1. 确定两端字符集

查询两端字符集:

select userenv('language') from dual;

如果相同则没有问题

如果不同

1)需要使用csscan工具对源端数据进行检测,查看数据导入到目标端后是否会出现字段长度不足,乱码等情况。csscan使用方法见附录。

2)需要在extract进程和replicat进程中设置环境变量NLS_LANG,均和源端数据库字符集一致即可。具体是否会出现乱码还需要测试。

4.1.2. 源端导出目标表

创建directory

create directory oggd as '/home/oracle';

导出目标表,FLASHBACK_SCN为之前确定的SCN3

expdp XPADB/XPADB DIRECTORY=oggd DUMPFILE=xpadb.`date '+%Y%m%d_%H%M'`.dmp.%U LOGFILE=xpadb.`date '+%Y%m%d_%H%M'`.log parallel=4 FLASHBACK_SCN=xxxxx

4.1.3. 调整目标端job_queue_processes

调整job_queue_processes0

SQL>show parameter job    (记录下来,之后还会调整回来)

SQL>alter system set job_queue_processes=0 scope=memory;

再次确认一下修改成功

SQL>show parameter job

4.1.4. 目标端数据库导入

impdp XPADRPT/xpadrpt DIRECTORY=oggd DUMPFILE=xpadb.20130620_1525.dmp.%U LOGFILE=impdp.xpadb.20160220_1525.log parallel=4 REMAP_SCHEMA=xpadb:xpadrpt REMAP_TABLESPACE=xpaddat:xpaddata

 

4.2. RMAN方式

4.2.1. 备份数据库

备份数据库、归档、控制文件:

$rman target /

run {

allocate channel c1 type disk;

allocate channel c2 type disk;

allocate channel c3 type disk;

allocate channel c4 type disk;

crosscheck backupset;

delete noprompt expired backupset;

backup as backupset full database tag='db_bak' format '/u01/backup/db_%U_%T';

sql 'alter system archive log current';

backup archivelog all tag='arc_bak' format='/u01/backup/arc_%U_%T' filesperset 6;

backup current controlfile tag='ctl_bak' format='/u01/backup/ctl_file_%U_%T';

release channel c1;

release channel c2;

release channel c3;

release channel c4;

}

4.2.2. 确定最终SCN

在源端刚备份完的数据库执行:

SQL>select GROUP# ,THREAD#,SEQUENCE#,ARCHIVED,STATUS,FIRST_CHANGE# from gv$log;

 

    GROUP#    THREAD#  SEQUENCE# ARC STATUS           FIRST_CHANGE#

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

         1          1        240 YES INACTIVE               1697423

         3          1        241 NO  CURRENT                1718793

         2          1        239 YES INACTIVE               1690905

 

获取不活动的已归档日志的最后一个SCN号,如果有多个已归档的INACTIVE的组,取最大的FIRST_CHANGE#,这里取1697423,该SCN号(SCN4)即为最终rman恢复和启动replicatscn号。(这个SCN4一定要比基准SCNSCN3)大)

注:如果是RAC环境要确保这个SCN号对应的日志两边都已经归档。

4.2.3. 拷贝备份、PFILE、密码文件到目标端

4.2.4. 目标端执行恢复

启动数据库到nomount状态

sqlplus '/ as sysdba'

SQL>startup nomount

启动RMAN恢复控制文件

rman target /

RMAN>restore controlfile from '/u01/backup/ctl_file_757366280381.dbf';

将数据库更改为mount状态

sqlplus '/ as sysdba'

SQL>alter database mount;

启动RMAN恢复数据库

rman target /

RMAN>restore database;

RMAN>

run

{

   set archivelog destination to '/u01/arch';

   SET UNTIL SCN 218412;     –前边确定的scn号 SCN4

   RECOVER DATABASE;

}

4.2.5. 调整目标端job_queue_processes

调整job_queue_processes0

SQL>show parameter job    (记录下来,之后还会调整回来)

SQL>alter system set job_queue_processes=0 scope=memory;

再次确认一下修改成功

SQL>show parameter job

 

4.2.6. 目标端打开数据库

开库

SQL>alter database open resetlogs;

5. 目标端数据库配置

5.1. 禁用所有job

5.1.1. dbms_job

禁用job

declare

v_sql number;

CURSOR c_job IS SELECT job from

dba_jobs where schema_user in

('JP');

BEGIN

OPEN c_job;

LOOP

FETCH c_job INTO v_sql;

EXIT WHEN c_job%NOTFOUND;

dbms_ijob.broken(v_sql,true);

end loop;

close c_job;

commit;

end;

/

验证job确实被禁用

select job,LOG_USER,PRIV_USER,SCHEMA_USER,broken from dba_jobs where schema_user in ('JP');

5.1.2. schedule job

禁用job

declare

v_sql varchar2(200);

CURSOR c_job IS SELECT OWNER||'.'||JOB_NAME from

DBA_SCHEDULER_JOBS where OWNER in

('JP');

BEGIN

OPEN c_job;

LOOP

FETCH c_job INTO v_sql;

EXIT WHEN c_job%NOTFOUND;

dbms_scheduler.disable(NAME =>v_sql);

end loop;

close c_job;

commit;

end;

/

验证job确实被禁用

SELECT OWNER,JOB_NAME,STATE FROM DBA_SCHEDULER_JOBS WHERE OWNER IN('JP');

5.1.3. 调整目标端job_queue_processes

将目标端job_queue_processes值调整回原值

5.2. 禁用所有trigger

declare

v_sql varchar2(2000);

CURSOR c_trigger IS SELECT 'alter trigger '||owner||'.'||trigger_name||' disable' from

dba_triggers where owner in

('JP');

BEGIN

OPEN c_trigger;

LOOP

FETCH c_trigger INTO v_sql;

EXIT WHEN c_trigger%NOTFOUND;

execute immediate v_sql;

end loop;

close c_trigger;

end;

/

确认trigger已经全部关闭

select distinct status from dba_triggers where owner in ('JP');

5.3. 禁用所有外键

禁用外键

declare

v_sql varchar2(2000);

CURSOR c_con IS SELECT 'alter table '||owner||'.'||table_name||' disable constraint

'||constraint_name from dba_constraints where constraint_type='R' and owner in

('JP');

BEGIN

OPEN c_con;

LOOP

FETCH c_con INTO v_sql;

EXIT WHEN c_con%NOTFOUND;

execute immediate v_sql;

end loop;

close c_con;

end;

/

确认外键已经被禁用

select OWNER,CONSTRAINT_NAME,CONSTRAINT_TYPE,STATUS

from dba_CONSTRAINTS

where CONSTRAINT_TYPE='R' and status = 'ENABLED' and owner in ('JP');

5.4. 确认目标端目标表的主键可用

select T1.STATUS,T1.VALIDATED,T2.status,T1.constraint_name,T1.owner

from dba_constraints T1,dba_objects T2  

where T2.OBJECT_NAME=T1.constraint_name AND T1.OWNER IN ('JP');

确认查询结果:

T1.STATUS为ENABLED

T1.VALIDATED为VALIDATED

T2.status为VALID

如果不是,需要修改为打开状态。

附录

csscan工具使用说明

工具csscan用于检查从一个字符集转换到另一个字符集,数据库中的数据是否会产生丢失、截断等现象。

本实验将ZHS16GBK转换到AL32UTF8

[oracle@dbserver1 bin]$ csscan userid=thams/thams table=libfile722 tochar=AL32UTF8 log=/home/oracle/scan_722

CSS-00127: user thams does not have DBA privilege

Scanner terminated unsuccessfully.

错误信息很明显,连接用户不是DBA角色,如果用system用户连接进行这个命令:

[oracle@dbserver1 bin]$ csscan userid=system/oracle table=thams.libfile722 tochar=AL32UTF8 log=/home/oracle/scan_722

调用csminst.sql脚本创建辅助用户和对象后,再次运行csscan工具,对表中数据进行转换前的扫描。

工具csscan的调用有命令行方式,和交互两种,当命令行没有提供足够的参数,工具会以交互方式获取其他参数。

操作完成后,可以检查对应的日志信息:
