OGG RAC模式单向复制
1、创建spilfle 备份?
create pfile='pfile_20150416' from spfile;
2、配置归档格式
alter system set log_archive_format='%t_%s_%r.arc' scope=spfile;
3、开启归档
节点1
SQL> alter system set log_archive_dest_1='location=/eip_arch1' sid='cwmdb1';
SQL> alter system set log_archive_dest_1='location=/eip_arch2' sid='cwmdb2';
关闭两个节点
shutdown immediate
然后分别将两个节点开启到mount模式
SQL> startup mount
节点1
SQL> alter database archivelog;
SQL> alter database open;
节点2
SQL> alter database open;
4、切换归档测试
alter system switch logfile;
环境说明：
数据同步源端： 操作系统：linux x86 64位，数据库版本 ORACLE 11.2.0.4 ，OGG版本：12.2.0.1
数据同步目标端：
操作系统：linux x86 64位，
数据库版本 ORACLE 11.2.0.4 ，
OGG版本：12.2.0.1
需要同步的表名：
序号 源系统 源用户 源表 目的用户 目标系统 目的表 备注
1 资产 "LCAM_SC " DM_TPV_SUBSTATION GG_LCAM_SC 决策支持 DM_TPV_SUBSTATION
2、资源申请（现有可忽略）
2.1、操作系统
申请在10.150.145.xxx、10.150.145.xxx、10.150.145.xxx新建用户ggs，三个节点用户uid一致，并且加入oinstall用户组
2.2、存储
申请300G磁盘空间，挂载在10.150.145.xxx的 /eam_ggs 目录，目录权限ggs:oinstall 644
源端操作：
2.3、在源端数据库开启强制日志重启操作系统
alter database force logging; --开启强制日志不需要重启
alter database add supplemental log data; --开启最小附加日志模式 ------
select log_mode,supplemental_log_data_min,force_logging from v$database; --验证是否开启数据库归档，附件日志，务必请先开数据库归档。
3、部署golden gate 12c （如现有可忽略）
3.1、设置环境变量
设置PATH和LD_LIBRARY_PATH环境变量：
将goldengate的安装目录加入到PATH变量里，同时将该安装目录也加入到LD_LIBRARY_PATH变量中。
这里有一点需要注意，在编辑LD_LIBRARY_PATH环境变量之前，需要确保oracle数据库库文件目录已经存在于该环境变量中，如果没有则需要将该目录加上，如：
export PATH
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORA_GRID_HOME=/u01/app/grid_home/
export OGG_HOME=/eam_ggs/ggs
export ORACLE_OWNER=gzodb
export ORACLE_SID=eam
export NLS_LANG=american_america.zhs16gbk
export PATH=$PATH:$ORACLE_HOME/bin:$ORA_GRID_HOME/bin:/sbin:/usr/sbin:/bin:/usr/local/bin:$OGG_HOME
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/lib32:/lib:/usr/lib:$ORACLE_HOME/rdbms/lib:$OGG_HOME
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/network/jlib
3.3、创建临时表，以便进行语句生成
create table GGS (owner varchar2(255),table_name varchar2(255));
3.4、将要同步的表 OWNER 及 TABLE NAME 插入 GGS 表
* 用上面生成的语句即可
3.5、确定对象类型，是表而不是视图、同义词（注意替换 DB_LINK 名称）
select owner,object_name,object_type from dba_objects@sjzy1 where (owner,object_name) in (select owner,table_name from ggs);
col owner for a30
col table_name for a30
col object_type for a30
set line 300 pages 999
select g.owner,g.table_name,o.object_type from ggs g left join dba_objects@sjzy1 o on o.owner=g.owner and o.object_name=g.table_name;
序号 源系统 源用户 源表 目标系统 目的用户 目的表 历史删除记录表 备注
10
17
24
3.6、表属性确认
有主键表
set colsep ','
col rownum for 9999
select rownum,owner,table_name from GGS where (UPPER(TRIM(owner)) , UPPER(TRIM(table_name))) in (select owner,table_name from dba_constraints@sjzy1 where constraint_type in ('P','U')) or (UPPER(TRIM(owner)) , UPPER(TRIM(table_name))) in (select owner,table_name from dba_indexes@sjzy1 where UNIQUENESS ='UNIQUE');
ROWNUM OWNER TABLE_NAME
1 LCAM_SC DM_TPV_SUBSTATION
2
3
无主键表
"set colsep ','"
col rownum 9999
"select rownum,owner,table_name from GGS "
" where (UPPER(TRIM(owner)) , UPPER(TRIM(table_name))) not in (select owner,table_name from dba_constraints@sjzy1 where constraint_type in ('P','U'))"
" and (UPPER(TRIM(owner)) , UPPER(TRIM(table_name))) not in (select owner,table_name from dba_indexes@sjzy1 where UNIQUENESS ='UNIQUE');"
ROWNUM "OWNER " TABLE_NAME
" 1"
3.7、附加日志确认
未添加附加日志
"select rownum,owner,table_name from GGS where (RTRIM(LTRIM(upper(owner),' '),' '),RTRIM(LTRIM(upper(table_name),' '),' ')) not in (select owner,table_name from dba_log_groups@sjzy1);"
ROWNUM "OWNER " TABLE_NAME
" 1" "LCAM_SC " DM_TPV_SUBSTATION
" 2"
" 3"
" 4"
3.8、日志模式检查（确认 LOG_MODE 为归档模式，SUPPLEMENTAL_LOG_DATA_MIN、 FORCE_LOGGING 为 YES）
select log_mode,supplemental_log_data_min,force_logging from v$database;
LOG_MODE SUPPLEME FOR
ARCHIVELOG YES YES
3.9、创建GoldenGate用户帐号(源端）
--确认
select username from dba_users where username='S_GG';
USERNAME
S_GG
--创建
create user s_gg identified by "sgg_123" ;
grant connect,resource,create session, alter session to s_gg;
grant select any dictionary, select any table,create table to s_gg;
grant alter any table to s_gg;
grant ALTER SYSTEM to s_gg;
grant execute on utl_file to s_gg;
grant flashback any table to s_gg;
grant execute on dbms_flashback to s_gg;
grant select any transaction to s_gg;
exec DBMS_GOLDENGATE_AUTH.GRANT_ADMIN_PRIVILEGE ('S_GG');
--如果同步ddl和序列需要授予DBA权限
3.10、UNDO 设置（根据官方文档来）
UNDO_MANAGEMENT=AUTO
UNDO_RETENTION=86400 --根据具体的需要进行评估
3.11、使用集成模式抽取数据，需要设置STREAMS_POOL_SIZE大小。
ALTER SYSTEM SET streams_pool_size=1024m scope = both;
3.12、开启数据库参数，以支持Integrated Capture
ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;
3.13、数据库账号口令加密
"GGSCI (mmgl-2 as s_gg@mmgl2) 25> encrypt password qwe1575!rty,ENCRYPTKEY default"
Using Blowfish encryption with DEFAULT key.
Encrypted password: AACAAAAAAAAAAALAYHBBHIZIKBNBNCXAYHUEFJPDBEDJKDUB
Algorithm used: BLOWFISH
登陆验证
dblogin USERID s_gg password AACAAAAAAAAAAALAYHBBHIZIKBNBNCXAYHUEFJPDBEDJKDUB, encryptkey default
或者
dblogin USERID s_gg, password AACAAAAAAAAAAALAYHBBHIZIKBNBNCXAYHUEFJPDBEDJKDUB, encryptkey default
3.14、添加附加日志
"从ggsci登陆,可从配置文件中使用加密过的 key 登录"
"dblogin USERID s_gg password AACAAAAAAAAAAALAGDQCEGSIEHIJPCMBQHEHEGRGZFZBFBZA, encryptkey default"
dblogin USERID s_gg password qwe1575!rty
添加附加日志
col ADD_TRANDDATA_STATEMENT_FORGGS for a150
"select 'add trandata '||owner||'.'||table_name as ADD_TRANDDATA_STATEMENT_FORGGS from GGS where (RTRIM(LTRIM(upper(owner),' '),' '),RTRIM(LTRIM(upper(table_name),' '),' ')) not in (select owner,table_name from dba_log_groups);"
ADD_TRANDDATA_STATEMENT_FORGGS
------------------------------------------------------------------------------------------------------------------------------------------------------
add trandata LCAM_SC.DM_TPV_SUBSTATION ALLCOLS
* 添加后按照 3.7 再次确认是否已经正常添加表级别附加日志
3.15、生成文件（抽取进程、投递进程同步清单）
set pages 9999 linesize 30000 long 50000 longc 99999
set echo off feedback off heading on termout off trimout off
set markup html on spool on pre off entmap off
spool table_column_list.html
"select 'TABLE '||b.owner||'.'||b.TABLE_NAME||', COLS ('||WMSYS.wm_concat(b.column_name)||');' as MAP_TABLE_COLUMN_FOR_GGS from GGS a, dba_tab_columns@sjzy1 b "
"where RTRIM(LTRIM(upper(a.owner),' '),' ')=b.owner and RTRIM(LTRIM(upper(a.table_name),' '),' ')=b.table_name group by b.owner,b.table_name;"
spool off
MAP_TABLE_COLUMN_FOR_GGS
【如需按表字段同步，如无此需要，请忽略】

【按表同步】
vi /zc_ggs/ggs/dirprm/e_eam.obey
=====================================
TABLE LCAM_SC.DM_TPV_SUBSTATION;
将上面的 TABLE 及 CLOUMN 添加到 obey 文件中
3.16、配置MGR进程
edit params mgr

exttrail G:\eam_ggs\dirdat\ea
numfiles 4000
dynamicresolution
OBEY G:\eam_ggs\dirprm\e_eam.obey
BR BRINTERVAL 30M
3.18、添加抽取进程（RAC）
ADD EXTRACT e_eam, tranlog, threads 2,BEGIN NOW
3.18、添加抽取进程（not RAC）
ADD EXTRACT e_eam, tranlog,BEGIN NOW
3.19、创建本地trail文件（从官方解释来看，这一步其实是声明，从哪个队列文件开始）
add exttrail G:\eam_ggs\dirdat\ea, extract e_eam
3.20、抽取进程注册
REGISTER EXTRACT e_eam DATABASE
3.21、配置投递进程
有主键
edit params d_eam
配置文件
extract d_eam
USERID s_gg password AACAAAAAAAAAAALAGDQCEGSIEHIJPCMBQHEHEGRGZFZBFBZA, encryptkey default
rmthost 10.124.250.75, mgrport 7809
rmttrail /usr/lib/ogg12.3_bigdata/dirdat/EVS/ea
nopassthru
--passthru
dynamicresolution
OBEY G:\eam_ggs\e_eam.obey
3.22、添加投递进程
add extract d_eam,exttrailsource G:\eam_ggs\dirdat\ea
3.23、创建远程trail文件
add rmttrail /usr/lib/ogg12.3_bigdata/dirdat/EVS/ea,EXTRACT d_eam, megabytes 100
3.23、启动进程
./ggsci
start e_eam
alter d_eam begin now
start d_eam
目标端配置：
3.24、如果ogg抽不到归档日志会报OGG-00446错误，可以设置重新抽取。
alter extract e_eam,begin now
3.24、生成数据表定义文件
a. 生成DEF文件
vi /yx_ggs/ggs/dirprm/xcjk_def.prm
DEFSFILE /yx_ggs/ggs/dirdef/xcjk.def
USERID s_gg password AACAAAAAAAAAAALAYHBBHIZIKBNBNCXAYHUEFJPDBEDJKDUB, encryptkey default
obey /yx_ggs/ggs/dirdef/xcjk_def.obey
b. 编辑 def所要使用obey
select 'table '||owner||'.'||table_name||';' from ggs;
vi /yx_ggs/ggs/dirdef/xcjk_def.obey
table LCAM_SC.DM_TPV_SUBSTATION;
b. GGHOME用defgen生成定义文件
mv /dump/yxyj_ggs/ggs12_1/dirdef/bos4gz.def /dump/yxyj_ggs/ggs12_1/dirdef/bos4gz.def.20180907
./defgen paramfile /dump/yxyj_ggs/ggs12_1/dirdef/bos4gz_def.prm NOEXTATTR
--NOEXTATTR 由于目标端是GG 11.2,所以才要加这个兼容性的参数
3.25、把生成dirdef文件copy到目标端复制进程的dirdef目录下
scp /dump/yxyj_ggs/ggs12_1/dirdef/bos4gz.def [email protected]:/dw_ggt/ggt12/dirdef/bos4gz.def
3.26、复制进程配置

3.28、添加复制进程
add replicat r_cw,exttrail /dw_ggt/ggt/dirdat/cw/cw
add replicat r_cw_d,exttrail /dw_ggt/ggt/dirdat/cw/cw
3.29、创建目标端存放数据用户
create user GG_IT_MEET identified by "GG_IT_MEET#123" default tablespace TS_GG_ODS_OT;
grant connect,resource to GG_IT_MEET;
3.30、创建DBLINK
create public database link to_cw connect to s_gg identified by "qwe1575!rty" using '(DESCRIPTION = (ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 10.150.145.xxx)(PORT = 1621)))(CONNECT_DATA =(SERVICE_NAME = CWPLUS)))';

select table_name,count(1) from dba_tab_columns where owner in ('GG_LCAM_ZC','GG_LCAM_SC') and column_name in ('ODS_OP_TYPE','ODS_S_DATE','ODS_T_DATE') having count(1) < 3 group by table_name;
3.34、创建存放delete数据的表
set line 200
select 'create table GG_'||owner||'.'||substr(table_name,1,26)||'_DEL as select * from GG_'||owner||'.'||table_name||' where 1=2;' from ggs ;
create table GG_LCAM_SC.DM_TPV_SUBSTATION_DEL as select * from GG_LCAM_SC.DM_TPV_SUBSTATION where 1=2;
--检查
select count(1) from dba_objects where owner in ('GG_LCAM_ZC','GG_LCAM_SC') and object_type='TABLE' and object_name like '%_DEL' and created >= to_date('20160922','yyyymmdd');
3.35、启动复制进程
stop replicat r_xcjk
stop replicat r_xcjk_de
start replicat r_xcjk
start replicat r_xcjk_de
使用 info all 查看进程状态，为 ABENDED 代表有问题
使用 stats r_xcjk 及 stats r_xcjk_de 查看进程复制记录数
