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.

如果沒有修改參數文件中的DB_NAME參數，那麽在MOUNT的時候，會報ORA-01103錯誤。
修改DB_NAME參數，嘗試直接打開數據庫。
提示必須使用RESETLOGS的方式才能打開數據庫。
默認情況下，db_unique_name 和service_names都會伴隨著DB NAME一起改變，此時由於service_names發生了變化，正常情況下應用是無法連接數據庫的(以SID連接方式除外)。
Oracle goldengate搭建ogg
主庫
設置環境變量（oracle用戶）
PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin:/ggs
export LD_LIBRARY_PATH=/ggs:$ORACLE_HOME/lib
1.檢查是否開啟歸檔
SQL> select log_mode fromgv$database;
SQL> archive log list; ----註意歸檔路徑需要是共享路徑
2.檢查是否開啟force logging及補充日誌
selectforce_logging,supplemental_log_data_min,supplemental_log_data_all,flashback_onfrom v$database;
開啟：
alter database force logging;
alter database add supplemental logdata;
alter system archive log current;
3.對主庫檢查，ogg不允許：唯一索引的索引列的列定義允許為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 = ‘自行添加用戶‘ -----修改用戶名
and dtc.OWNER = ‘自行添加用戶‘ -----修改用戶名
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;
不應該返回行，如果返回了，修改：要麽變為非唯一索引，要麽在保留唯一索引的情況下，將列的定義置為 not null。
4.創建ogg用戶，並授權
create user ogg identified by ogg default tablespaceusers;
grant dba to ogg;
ALTER SYSTEM SETENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;
5.檢查是否有nologing方式的表（ogg不支持nologing方式創建的表）
select owner,table_name,logging fromdba_tables where logging=‘NO‘ AND owner=‘用戶名‘;
修改為logging的表的語法：alter table 表名 logging;
註意：在ext進程的參數文件裏添加 dboptions allownologging可以讓ext進程繼續運行，但是會導致數據丟失。
6.源端數據庫添加表的補充日誌
進入ogg安裝路徑：
ggsci
dblogin userid ogg password ogg
GGSCI (oggsource) 1> dblogin userid ogg password ogg

GGSCI (oggsource as [email protected]) 2>addtrandata lm.testogg
-------------------為表添加附加日誌，以便goldengate進行redo的抽取以及應用。
7.配置DDL復制
使用ogg作為存儲DDL objects的用戶給ogg授權：
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.數據庫執行：
退出所有的oracle連接後執行：
cd /ggs
sqlplus / as sysdba

11、配置管理進程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進程參數配置說明：
PORT：指定服務監聽端口；這裏以7839為例，默認端口為7809
DYNAMICPORTLIST：動態端口：可以制定最大256個可用端口的動態列表，當指定的端口不可用時，管理進程將會從列表中選擇一個可用的端口，源端和目標段的Collector、Replicat、GGSCI進程通信也會使用這些端口；
COMMENT：註釋行，也可以用--來代替;
AUTOSTART：指定在管理進程啟動時自動啟動哪些進程；
AUTORESTART：自動重啟參數設置：本處設置表示每3分鐘嘗試重新啟動所有EXTRACT進程，共嘗試5次；
PURGEOLDEXTRACTS：定期清理trail文件設置：本處設置表示對於超過3天的trail文件進行刪除。
LAGREPORT、LAGINFO、LAGCRITICAL：
定義數據延遲的預警機制：本處設置表示MGR進程每隔1小時檢查EXTRACT的延遲情況，如果超過了30分鐘就把延遲作為信息記錄到錯誤日誌中，如果延遲超過了45分鐘，則把它作為警告寫到錯誤日誌中。
12、配置extfull
add extract extfull, tranlog,begin now
edit param extfull
extract extfull
setenv ( NLS_LANG = " AMERICAN_AMERICA.ZHS16GBK " )------添加報錯
TRANLOGOPTIONS [email protected], ASMPASSWORD oracle

add exttrail /u01/app/oracle/ogg/dirdat/sd, extractextfull, MEGABYTES 50
13.添加傳輸進程
添加傳輸進程
addextract dpfull exttrailsource /ggs/dirdat/sd
創建遠程隊列文件並將其指定給傳輸進程
addrmttrail /u01/app/oracle/ogg/td, extract dpfull, MEGABYTES 50
配置傳輸進程參數
editparam dpfull
==================================
extractdpfull
passthru
rmthost 186.168.100.22, mgrport 7809
rmttrail /ggs/dirdat/td
gettruncates
table LM.testogg;
12、啟動管理進程：
dblogin userid ogg password ogg
GGSCI (oggsource as [email protected]) 11>start mgr
Manager started.
查看進程狀態可發現 MANAGER狀態為 RUNNING：
GGSCI(NDSCDB1) 3> info all
/u01/app/oracle/ogg/dirrpt
13、配置抽取進程：
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:指定隊列大小，本處設置表示100M。
添加傳輸進程，配置參數
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")

抽取進程和傳輸進程其實都是EXTRACT進程，也可以配置在一個進程完成這兩個功能，但是當網絡傳輸有問題時，這樣抽取也就不能繼續運行了，所以推薦分開配置為兩個進程；
EXTRACT進程參數配置說明：
SETENV：配置系統環境變量
USERID/ PASSWORD：指定OGG連接數據庫的用戶名和密碼，這裏使用3.4部分中創建的數據庫用戶OGG;
COMMENT：註釋行，也可以用--來代替;
TABLE：定義需復制的表，後面需以；結尾
TABLEEXCLUDE：定義需要排除的表，如果在TABLE參數中使用了通配符，可以使用該參數指定排除掉得表。
GETUPDATEAFTERS|IGNOREUPDATEAFTERS：
是否在隊列中寫入後影像，缺省復制
GETUPDATEBEFORES| IGNOREUPDATEBEFORES：
是否在隊列中寫入前影像，缺省不復制
GETUPDATES|IGNOREUPDATES：
是否復制UPDATE操作，缺省復制
GETDELETES|IGNOREDELETES：
是否復制DELETE操作，缺省復制
GETINSERTS|IGNOREINSERTS：
是否復制INSERT操作，缺省復制
GETTRUNCATES|IGNORETRUNDATES：
是否復制TRUNCATE操作，缺省不復制；
RMTHOST：指定目標系統及其GoldengateManager進程的端口號，還用於定義是否使用壓縮進行傳輸，本例中的compress為壓縮傳輸；
RMTTRAIL：指定寫入到目標斷的哪個隊列；
EXTTRAIL：指定寫入到本地的哪個隊列；
SQLEXEC：在extract進程運行時首先運行一個SQL語句；
PASSTHRU：禁止extract進程與數據庫交互，適用於DataPump傳輸進程；
REPORT：定義自動定時報告；
STATOPTIONS：定義每次使用stat時統計數字是否需要重置；
REPORTCOUNT：報告已經處理的記錄條數統計數字；
TLTRACE：打開對於數據庫日誌的跟蹤日誌；
DISCARDFILE：定義discardfile文件位置，如果處理中油記錄出錯會寫入到此文件中；
DBOPTIONS：指定對於某種特定數據庫所需要的特殊參數；
TRANLOGOPTIONS：指定在解析數據庫日誌時所需要的特殊參數，例如：對於裸設備，可能需要加入以下參數 rawdeviceoggset 0
WARNLONGTRANS：指定對於超過一定時間的長交易可以在gsserr.log裏面寫入警告信息，本處配置為每隔3分鐘檢查一次場交易，對於超過2小時的進行警告；~

參數介紹：
REPLICAT RINI_1：說明這是REPLICAT應用進程，名字叫RINI_1
SETENV：語言變量，同捕獲進程EINI_1
ASSUMETARGETDEFS：告訴OGG目標端和源端需要同步的表的結構完全一致，不需要OGG去檢查表的結構，包括表名、字段名、字段類型、字段長度等，如果目標端和源端同步的表的結構不一樣，需要使用SOURCEDEFS參數，詳見OGG官方文檔。
USERID、PASSWORD：同捕獲進程EINI_1參數介紹
DISCARDFILE：錯誤信息存放位置及命名規則
MAP：源端捕獲的表的名字
TARGET：目標端同步的表的名字，可以不在同一SCHEMA。
測試檢查
