创建pfile

RMAN> sql "create spfile from pfile";

新spfile启动

RMAN> startup nomount;

RMAN> startup force nomount;

2、恢复控制文件

RMAN> restore controlfile from ‘/u01/backup/full_t953113527_s3_p1‘;

Starting restore at 27-AUG-17

allocated channel: ORA_DISK_1

3、启动数据库到加载状态

RMAN> alter database mount;

RMAN> catalog start with ‘/backup/‘;

RMAN> restore database;

RMAN> recover database;

RMAN>alter database open resetlogs 打开数据库

nid target=/as sysdba dbname=stream

[[email protected] dbs]$ nid target=/assysdba dbname=stream

DBNEWID: Release 11.2.0.4.0 - Production onSun Aug 27 12:31:08 2017

Password:

Instance shut down

Database name changed to STREAM.

Modify parameter file and generate a newpassword file before restarting.

Database ID for database STREAM changed to1719130576.

All previous backups and archived redo logsfor this database are unusable.

Database is not aware of previous backupsand archived logs in Recovery Area.

Database has been shutdown, open databasewith RESETLOGS option.

Succesfully changed database name and ID.

DBNEWID - Completed succesfully.

如果没有修改参数文件中的DB_NAME参数，那么在MOUNT的时候，会报ORA-01103错误。

修改DB_NAME参数，尝试直接打开数据库。

提示必须使用RESETLOGS的方式才能打开数据库。

默认情况下，db_unique_name 和service_names都会伴随着DB NAME一起改变，此时由于service_names发生了变化，正常情况下应用是无法连接数据库的(以SID连接方式除外)。

Oracle goldengate搭建ogg

主库

设置环境变量（oracle用户）

PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin:/ggs

export LD_LIBRARY_PATH=/ggs:$ORACLE_HOME/lib

1.检查是否开启归档

SQL> select log_mode fromgv$database;

SQL> archive log list; ----注意归档路径需要是共享路径

2.检查是否开启force logging及补充日志

selectforce_logging,supplemental_log_data_min,supplemental_log_data_all,flashback_onfrom v$database;

开启：

alter database force logging;

alter database add supplemental logdata;

alter system archive log current;

3.对主库检查，ogg不允许：唯一索引的索引列的列定义允许为null的

select dic.table_owner,

dic.table_name,

dic.index_name,

di.uniqueness,

dic.column_name

from dba_ind_columns dic, dba_indexes di, dba_tab_columns dtc

where dic.table_owner = ‘自行添加用户‘ -----修改用户名

and dtc.OWNER = ‘自行添加用户‘ -----修改用户名

AND dic.table_owner = di.table_owner

and dic.TABLE_NAME = di.table_name

and dic.index_name = di.index_name

and di.uniqueness = ‘UNIQUE‘

and dtc.owner = di.table_owner

and dtc.TABLE_NAME = di.table_name

and dic.column_name = dtc.COLUMN_NAME

and dtc.nullable = ‘ Y ‘

anddic.TABLE_NAME = dtc.TABLE_NAME;

不应该返回行，如果返回了，修改：要么变为非唯一索引，要么在保留唯一索引的情况下，将列的定义置为 not null。

4.创建ogg用户，并授权

create user ogg identified by ogg default tablespaceusers;

grant dba to ogg;

ALTER SYSTEM SETENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;

5.检查是否有nologing方式的表（ogg不支持nologing方式创建的表）

select owner,table_name,logging fromdba_tables where logging=‘NO‘ AND owner=‘用户名‘;

修改为logging的表的语法：alter table 表名 logging;

注意：在ext进程的参数文件里添加 dboptions allownologging可以让ext进程继续运行，但是会导致数据丢失。

6.源端数据库添加表的补充日志

进入ogg安装路径：

ggsci

dblogin userid ogg password ogg

GGSCI (oggsource) 1> dblogin userid ogg password ogg

Successfully logged into database.

GGSCI (oggsource as [email protected]) 2>create subdirs

Dump files /u01/app/oracle/ogg/dirdmp: already exists

GGSCI (oggsource as [email protected]) 2>addtrandata lm.testogg

-------------------为表添加附加日志，以便goldengate进行redo的抽取以及应用。

7.配置DDL复制

使用ogg作为存储DDL objects的用户给ogg授权：

SQL> GRANT EXECUTE ON UTL_FILE TO ogg;

8.配置GLOBALS文件

ggsci

edit param ./GLOBALS中加入：

GGSCHEMA goldengate

如果是10g需要停用 recyclebin，11g就不需要了

9.数据库执行：

退出所有的oracle连接后执行：

cd /ggs

sqlplus / as sysdba

@marker_setup.sql

SQL> @marker_setup.sql

10.源端配置参数文件

su - grid

vi$ORACLE_HOME/network/admin/listener.ora

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = +ASM)

(ORACLE_HOME=/u01/app/11.2.0/grid)

(SID_NAME = +ASM1)

. )

.su - oracle

.cd $ORACLE_HOME/network/admin

.vi tnsnames.ora

.ASM =

. (DESCRIPTION =

. (ADDRESS = (PROTOCOL = TCP)(HOST = 186.168.100.3)(PORT = 1521))

. (CONNECT_DATA =

. (SERVER = DEDICATED)

. (SERVICE_NAME = +ASM)

. (SID_NAME = +ASM1)

. )

11、配置管理进程mgr：

GGSCI(NDSCDB1) 1> edit param mgr

port 7809

-- DYNAMICPORTLIST 7830-7835

autostart extract *

autorestart extract *, waitminutes 1,retries 60, RESETMINUTES 60

PURGEOLDEXTRACTS /ggs/dirdat/sd*,USECHECKPOINTS, MINKEEPHOURS 2

~ MANAGER进程参数配置说明：

PORT：指定服务监听端口；这里以7839为例，默认端口为7809

DYNAMICPORTLIST：动态端口：可以制定最大256个可用端口的动态列表，当指定的端口不可用时，管理进程将会从列表中选择一个可用的端口，源端和目标段的Collector、Replicat、GGSCI进程通信也会使用这些端口；

COMMENT：注释行，也可以用--来代替;

AUTOSTART：指定在管理进程启动时自动启动哪些进程；

AUTORESTART：自动重启参数设置：本处设置表示每3分钟尝试重新启动所有EXTRACT进程，共尝试5次；

PURGEOLDEXTRACTS：定期清理trail文件设置：本处设置表示对于超过3天的trail文件进行删除。

LAGREPORT、LAGINFO、LAGCRITICAL：

定义数据延迟的预警机制：本处设置表示MGR进程每隔1小时检查EXTRACT的延迟情况，如果超过了30分钟就把延迟作为信息记录到错误日志中，如果延迟超过了45分钟，则把它作为警告写到错误日志中。

12、配置extfull

add extract extfull, tranlog,begin now

edit param extfull

extract extfull

setenv ( NLS_LANG = " AMERICAN_AMERICA.ZHS16GBK " )------添加报错

TRANLOGOPTIONS [email protected], ASMPASSWORD oracle

NOCOMPRESSDELETES

table LM.testogg;

add exttrail /u01/app/oracle/ogg/dirdat/sd, extractextfull, MEGABYTES 50

13.添加传输进程

添加传输进程

addextract dpfull exttrailsource /ggs/dirdat/sd

创建远程队列文件并将其指定给传输进程

addrmttrail /u01/app/oracle/ogg/td, extract dpfull, MEGABYTES 50

配置传输进程参数

editparam dpfull

==================================

extractdpfull

passthru

rmthost 186.168.100.22, mgrport 7809

rmttrail /ggs/dirdat/td

gettruncates

table LM.testogg;

12、启动管理进程：

dblogin userid ogg password ogg

GGSCI (oggsource as [email protected]) 11>start mgr

Manager started.

查看进程状态可发现 MANAGER状态为 RUNNING：

GGSCI(NDSCDB1) 3> info all

/u01/app/oracle/ogg/dirrpt

13、配置抽取进程：

GGSCI (oggsource as [email protected]) 12> addextract extnd,tranlog,begin now

EXTRACT added.

GGSCI (oggsource as [email protected]) 13> addexttrail ./dirdat/nd,extract extnd,megabytes 100

EXTTRAIL added.

Megabytes:指定队列大小，本处设置表示100M。

添加传输进程，配置参数

GGSCI(NDSCDB1) 15> edit params extnd

EXTRACT extnd

setenv(NLS_LANG ="AMERICAN_AMERICA.ZHS16GBK")

SETENV(ORACLE_HOME ="/u01/app/oracle/product/11.2.0/db_1")

抽取进程和传输进程其实都是EXTRACT进程，也可以配置在一个进程完成这两个功能，但是当网络传输有问题时，这样抽取也就不能继续运行了，所以推荐分开配置为两个进程；

EXTRACT进程参数配置说明：

SETENV：配置系统环境变量

USERID/ PASSWORD：指定OGG连接数据库的用户名和密码，这里使用3.4部分中创建的数据库用户OGG;

COMMENT：注释行，也可以用--来代替;

TABLE：定义需复制的表，后面需以；结尾

TABLEEXCLUDE：定义需要排除的表，如果在TABLE参数中使用了通配符，可以使用该参数指定排除掉得表。

GETUPDATEAFTERS|IGNOREUPDATEAFTERS：

是否在队列中写入后影像，缺省复制

GETUPDATEBEFORES| IGNOREUPDATEBEFORES：

是否在队列中写入前影像，缺省不复制

GETUPDATES|IGNOREUPDATES：

参数介绍：

REPLICAT RINI_1：说明这是REPLICAT应用进程，名字叫RINI_1

SETENV：语言变量，同捕获进程EINI_1

ASSUMETARGETDEFS：告诉OGG目标端和源端需要同步的表的结构完全一致，不需要OGG去检查表的结构，包括表名、字段名、字段类型、字段长度等，如果目标端和源端同步的表的结构不一样，需要使用SOURCEDEFS参数，详见OGG官方文档。

USERID、PASSWORD：同捕获进程EINI_1参数介绍

DISCARDFILE：错误信息存放位置及命名规则

MAP：源端捕获的表的名字

TARGET：目标端同步的表的名字，可以不在同一SCHEMA。

测试检查

info all---------------------检查进程

info 进程名,detail

stats REPFULL-----------------------------检查数据传输状态

view report 进程名

数据库登录检查数据是否有变化
