昨天突然接到消息說有一個線上的ogg出現了問題，看是否能修復，由於ogg以前玩的少，所以就加急搞了個測試環境，練習了一把
環境
db1,db2(單實例)
ip: 1*,1*
sid: orcl,ogg1
os: centos 6.5,centos 6.5
oracle version: 11.2.0.4,11.2.0.4
1 --可以創建ogg用戶，也可以使用oracle用戶
useradd -u 2100 -g oinstall -G dba ogg
passwd ogg
[ogg@DSI ~]$ vim .bash_profile export LD_LIBRARY_PATH=/u01/app/oracle/product/11.2.0/db_1/lib export ORACLE_SID=orcl export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:$PATH [ogg@DSI ~]$ source .bash_profile
2 下載安裝ogg
[root@DSI ~]# mkdir -p /u01/app/ogg [root@DSI ~]# chown -R oracle:oinstall /u01/app/ogg [root@DSI opt]# unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip Archive: ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip inflating: fbo_ggs_Linux_x64_ora11g_64bit.tar inflating: OGG_WinUnix_Rel_Notes_11.2.1.0.1.pdf inflating: Oracle GoldenGate 11.2.1.0.1 README.txt inflating: Oracle GoldenGate 11.2.1.0.1 README.doc [root@DSI opt]# tar -xvf fbo_ggs_Linux_x64_ora11g_64bit.tar -C /u01/app/ogg/ [root@DSI ogg]# chown -R oracle:oinstall /u01/app/ogg
解壓成功之后，登錄OGG測試

4 開始進行搭建
源 orcl
1 創建 OGG 的管理目錄
GGSCI (DSI) 1> create subdirs Creating subdirectories under current directory /u01/app/ogg Parameter files /u01/app/ogg/dirprm: already exists Report files /u01/app/ogg/dirrpt: created Checkpoint files /u01/app/ogg/dirchk: created Process status files /u01/app/ogg/dirpcs: created SQL script files /u01/app/ogg/dirsql: created Database definitions files /u01/app/ogg/dirdef: created Extract data files /u01/app/ogg/dirdat: created Temporary files /u01/app/ogg/dirtmp: created Stdout files /u01/app/ogg/dirout: created

3 源端添加表級 TRANDATA
GGSCI (DSI) 2> DBLOGIN USERID ogg, PASSWORD ogg Successfully logged into database. GGSCI (DSI) 3> add trandata scott.emp_ogg Logging of supplemental redo log data is already enabled for table SCOTT.EMP_OGG. GGSCI (DSI) 4> add trandata scott.dept_ogg Logging of supplemental redo log data is already enabled for table SCOTT.DEPT_OGG. GGSCI (DSI) 5> INFO TRANDATA scott.* Logging of supplemental redo log data is disabled for table SCOTT.BONUS. Logging of supplemental redo log data is disabled for table SCOTT.DEPT. Logging of supplemental redo log data is enabled for table SCOTT.DEPT_OGG. Columns supplementally logged for table SCOTT.DEPT_OGG: DEPTNO.

Columns supplementally logged for table SCOTT.EMP_OGG: EMPNO. Logging of supplemental redo log data is disabled for table SCOTT.SALGRADE.
4 配置 MGR 管理進程
GGSCI (DSI) 6> edit params mgr PORT 7809 PURGEOLDEXTRACTS /u01/app/ogg/dirdat, USECHECKPOINTS 參數說明： PORT 7809： OGG 管理進程監控端口。 PURGEOLDEXTRACTS：清除不需要的 trail 文件。 /u01/app/ogg/dirdat： trail 文件存放位置。 USECHECKPOINTS：使用檢查點隊列 GGSCI (DSI) 7> start mgr Manager started. GGSCI (DSI) 8> info mgr Manager is running (IP port DSI.7809).
5 配置初始化數據進程
由於在創建測試表的時候，源端的測試表有數據，而目標端的測試表只有結構，沒有數據，所以需要初始
化目標端的數據，所謂初始化，就是讓目標端的數據和源端的數據在這個時間點是一模一樣的， 所以初始化工
作並不需要一定使用 OGG，也可以使用 EXP、 EXPDP、 SQLLOAD 等其他工具
##使用 OGG 進行數據初始化， 下面在源端配置捕獲進程 EINI_1
GGSCI (DSI) 9> ADD EXTRACT EINI_1, SOURCEISTABLE EXTRACT added. GGSCI (DSI) 10> INFO EXTRACT *, TASKS EXTRACT EINI_1 Initialized 2019-06-19 14:00 Status STOPPED Checkpoint Lag Not Available Log Read Checkpoint Not Available First Record Record 0 Task SOURCEISTABLE GGSCI (DSI) 11> EDIT PARAMS EINI_1 EXTRACT EINI_1 SETENV (NLS_LANG=AMERICAN_AMERICA.AL32UTF8) USERID ogg, PASSWORD ogg RMTHOST 1*, MGRPORT 7809 RMTTASK REPLICAT, GROUP RINI_1 TABLE scott.EMP_OGG; TABLE scott.DEPT_OGG; 參數介紹： EXTRACT EINI_1：說明這是 EXTRACT 進程，名字是 EINI_1 SETENV：環境變量，一定要設置和數據庫字符集一樣，否則可能會亂碼 USERID：數據庫 OGG 用戶 PASSWORD：數據庫用戶 OGG 的密碼 RMTHOST：目標端地址，如果在/etc/hosts 文件里已經設置解析，可以寫主機名 MGRPORT：目標端 MGR 管理進程監聽的端口 RMTTASK REPLICAT：目標端 REPLICAT 應用進程的組和名字 TABLE：源端要初始化數據的表的名字
編輯好捕獲進程 EINI_1 后， 還需要在目標端配置 REPLICAT 應用進程，名字要和源端的捕獲進程 EINI_1 里面 RMTTASK REPLICAT 參數配置的一樣，
也就是還需要在目標端配置 RMTTASK REPLICAT RINI_1
目 ogg [oracle@ogg ~]$ alias ggsci="/u01/app/ogg/ggsci" [oracle@ogg ~]$ ggsci GGSCI (ogg) 1> create subdirs Creating subdirectories under current directory /u01/app/ogg Parameter files /u01/app/ogg/dirprm: already exists Report files /u01/app/ogg/dirrpt: created Checkpoint files /u01/app/ogg/dirchk: created Process status files /u01/app/ogg/dirpcs: created SQL script files /u01/app/ogg/dirsql: created Database definitions files /u01/app/ogg/dirdef: created Extract data files /u01/app/ogg/dirdat: created Temporary files /u01/app/ogg/dirtmp: created Stdout files /u01/app/ogg/dirout: created 目標端 GGSCI (ogg) 2> edit params mgr PORT 7809 PURGEOLDEXTRACTS /u01/app/ogg/dirdat, USECHECKPOINTS GGSCI (ogg) 3> start mgr Manager started. GGSCI (ogg) 4> info mgr Manager is running (IP port ogg.7809).
7 配置目標端 REPLICAT 進程
GGSCI (ogg) 5> EDIT PARAMS RINI_1 REPLICAT RINI_1 SETENV (NLS_LANG=AMERICAN_AMERICA.AL32UTF8) ASSUMETARGETDEFS USERID ogg, PASSWORD ogg DISCARDFILE /u01/app/ogg/dirrpt/RINIaa.dsc, PURGE MAP scott.*, TARGET scott.*; 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。
8 初始化數據
配置好目標端的應用進程 RINI_1 后， 就可以啟動源端的捕獲進程進行捕獲數據了，而目標端的應用進程 RINI_1 不需要手動去啟動，也就是說目標端 RINI_1 進程不需要管
GGSCI (DSI) 12> START EXTRACT EINI_1 Sending START request to MANAGER ...

初始化之后，上文提到的初始化進程（EINI_1、 RINI_1）自動停止， 因為通常情況下初始化數據工作只會做一次。 可以通過 INFO 命令查看進程的狀態

10 源端和目標端配置 OGG 的檢查點
此步驟不是必須的，但是為了讓 OGG 網絡中斷、服務器宕機、掉電等在突發情況也能正確斷點續傳， ORACLE 建議配置 OGG 的檢查點隊列。
源端和目標端都需配置

12 源端配置 PUMP 傳輸進程
##此步驟也是非必須的，如果不配置傳輸進程， OGG 會通過 EXTRACT 進程傳輸 TRAIL 隊列文件，但是和檢查點隊列一樣，為了保證斷點續傳 ORACLE 建議配置 PUMP 傳輸進程
GGSCI (DSI) 8> EDIT PARAMS PORA_1 EXTRACT PORA_1 SETENV (NLS_LANG=AMERICAN_AMERICA,AL32UTF8) PASSTHRU RMTHOST *, MGRPORT 7809 RMTTRAIL /u01/app/ogg/dirdat/pa TABLE scott.EMP_OGG; TABLE scott.DEPT_OGG; ##添加 PUMP 進程 PORA_1 到 OGG，並指定本地的 TRAIL 文件。 GGSCI (DSI) 9> ADD EXTRACT PORA_1, EXTTRAILSOURCE /u01/app/ogg/dirdat/aa EXTRACT added.

至此 簡單的單實例單向同步已經完成
注明：此文檔跟網上有些文檔類似，因為臨時的原因，在我以前下載的資料里面找的pdf進行測試，發現是一個很早的pdf，找不到原文鏈接---
這里的實驗測試完全真實有效~~
后面會測試：修改表的同步，新增表的同步，雙向同步，以及切換等
其他mgr，等一些命令參數，官網或者網上有大部分的資料，這里不做列舉，因為還沒研究這些（~~~）
