OGG19.1 oracle12c到oracle12c經典和整合模式配置實施

  1. 目的說明
    本文提供Oracle GoldenGate在Oracle db到Oracle db的資料複製安裝配置指導,適用於入門練習使用,生產環境配置,在關鍵步驟和重要引數設定需要小心對待。
    OGG19.1 oracle12c到oracle12c經典和整合模式配置實施 ---- 支援DDL複製配置。

  2. 參考文件
    《叱吒風雲GoldenGate企業級運維實戰》
    Oracle GoldenGate Document 12.3.0/19.1.0

  3. 準備系統
    準備好兩套已經裝好Oracle db和Oracle GoldenGate for Oracle的環境。

GoldenGate:
ogg type:GoldenGate for Oracle 19.1.0.0.4

  1. 配置source db
    4.1 配置source db引數
    source db的配置主要是歸檔模式修改、附加日誌的新增、強制日誌和--ddl語句的支援。

      --#源端DB開啟歸檔模式和最小附加日誌
     
     --4.1.1 源端DB開啟歸檔模式
     archive log list
      --#啟用主動歸檔
      -- 關閉並mount資料庫
     shutdown immediate
     startup mount
      -- 開啟歸檔日誌
     alter database archivelog;
      -- 設定本地歸檔路徑
     alter system set log_archive_dest_1='location=/oradata/oggsdb/archive' scope=spfile;
      -- 設定歸檔日誌檔名格式
     show parameter  log_archive_format
     ----default    %t_%s_%r.dbf
     alter system set log_archive_format='oggsdb_%t_%s_%r.arc' scope=spfile;
      --關閉資料庫,再啟動資料庫 ,使引數 log_archive_dest_1生效
     shutdown immediate
     startup
      --檢查配置和引數生效
     archive log list
     show parameter log_archive_dest_1
     show parameter log_archive_format
     
     -- 4.1.2 強制日誌變更
     alter database force logging;  --實時生效  強制日誌
     --ALTER DATABASE NO FORCE LOGGING;
     
     -- 4.1.3 開啟最小附加日誌 和 檢視最小附加日誌
     alter database add supplemental log data;  --實時生效   最小附加日誌
     --alter database drop supplemental log data;
     
     
      --檢視source db歸檔、附加日誌和強制日誌:
     select supplemental_log_data_min from v$database;
     select db.LOG_MODE, db.SUPPLEMENTAL_LOG_DATA_MIN, db.FORCE_LOGGING from v$database db;
     
     select db.NAME,
            db.LOG_MODE,
            db.FLASHBACK_ON,
            db.FORCE_LOGGING, 
            db.supplemental_log_data_min,
            db.supplemental_log_data_pk,
            db.supplemental_log_data_ui,
            db.supplemental_log_data_ui,
            db.supplemental_log_data_fk,
            db.supplemental_log_data_all,
            db.supplemental_log_data_pl
       from v$database db;
     
             
     -- 4.1.4  修改GoldenGate引數
     show parameter enable_goldengate_replication
     
     alter system set enable_goldengate_replication = true scope = both;
     
     show parameter enable_goldengate_replication
     
     
     -- 4.1.5 建立GoldenGate使用者
     create tablespace ogg_data datafile '/oradata/oggsdb/ogg_data01.dbf' size 50M autoextend on next 8M;
     create user ogg identified by Password123 default tablespace ogg_data  quota unlimited on ogg_data;

     --4.1.6 配置DDL語句支援 ( Support for DDL Capture in Classic Capture Mode ) 
     --Classic capture mode requires the use of the Oracle GoldenGate DDL trigger to
     --capture DDL from an Oracle Database. Native DDL capture is not supported by classic capture mode.

     --   (Optional)To cause user DDL activity to fail when the DDL tablespace fills up, edit the params.sql script 
     --   and set the ddl_fire_error_in_trigger parameter to TRUE. As a best practice, make certain to size the tablespace appropriately in the first place.
     #params.sql內容
     define the ddl_fire_error_in_trigger = 'TRUE'
     define allow_invisible_index_keys = 'TRUE'
     #To enable trigger-based DDL replication to recognize Oracle invisible indexes as
     #unique identifiers, set the following parameter to TRUE in the params.sql script:
     
     --c. 此可暫時忽略
     --#at the root of the Oracle GoldenGate directory. Do not alterthe file name or location.
     EDIT PARAMS ./GLOBALS
     # 內容

     ##Save and close the GLOBALS file and the params.sql file.

     #Change directories to the Oracle GoldenGate installation directory.
     # ----The specific location is: oggma_install_home/lib/sql/legacy.
     #Exit all Oracle sessions. Prevent the start of any new sessions.
     進入GoldenGate目錄,呼叫SQL指令碼:
     cd $OGG_HOME
     sqlplus / as sysdba
     
     SQL> @marker_setup.sql;
     #輸入準備好的使用者ogg
     
     SQL> @ddl_setup.sql;
     #輸入準備好的使用者ogg 
     
     SQL> @role_setup.sql;
     #輸入準備好的使用者ogg 
     #Grant the role that was created (default name is GGS_GGSUSER_ROLE) to all Oracle GoldenGate Extract users.
     #根據上面執行結果的提示授權角色給ogg使用者
     SQL> grant GGS_GGSUSER_ROLE to ogg;
     
     
     SQL> @ddl_enable.sql;
     
     ##To Install and Use the Optional Performance Tool

--建立資料目錄(可在dirdat目錄下為 oggsdb的抽取程式建立一個單獨資料存放目錄 )
--cd $OGG_HOME
--oracle[/oradata/ogg]$mkdir -p dirdat/oggsdb
---- /oradata/ogg/dirdat/oggsdb

編輯配置manager引數檔案 :
GGSCI > edit params mgr

新增以下內容

對需要的表新增trandata

cd $OGG_HOME
./ggsci

GGSCI > dblogin userid ogg@oggsdb password Password123
Successfully logged into database.

GGSCI > add trandata scott.emp
--info trandata scott.emp
--select * from DBA_LOG_GROUPS

4.3 配置source db extract程式
--select * from nls_database_parameters

新增一個extract程式 :
GGSCI > add extract exggsdb,tranlog,begin now ----, threads 2

編輯extract引數檔案:
GGSCI (dbserver) 13> edit params exggsdb

新增以下內容

extract exggsdb
setenv (ORACLE_SID = "OGGSDB")
setenv (NLS_LANG = "AMERICAN_AMERICA.AL32UTF8")
userid ogg@oggsdb, password Password123
TRANLOGOPTIONS DBLOGREADER

table SCOTT.EMP;

建立本地trail檔案 :

GGSCI > add exttrail /oradata/ogg/dirdat/oggsdb/ex, extract exggsdb
EXTTRAIL added.

4.4 配置source db pump程式
新增一個pump程式(本質上也是extract程式),並指定遠端trail檔案:

GGSCI > add extract ppggsdb,exttrailsource /oradata/ogg/dirdat/oggsdb/ex
EXTRACT added.

編輯pump引數檔案:
GGSCI (dbserver) 16> edit params ppggsdb

新增以下內容

extract ppggsdb
passthru
rmthost 192.168.6.20, mgrport 7809 ---- target db主機ip,管理程式埠號 ##共用同一臺主機的mgr程式 測試
rmttrail /oradata/ogg/dirdat/oggtdb/pp
--ddl -- DDL support parameter
table scott.emp;

指定遠端trail檔案:
GGSCI > add rmttrail /oradata/ogg/dirdat/oggtdb/pp, extract ppggsdb
RMTTRAIL added.

4.5 啟動source程式

檢視extrac程式,啟動程式後注意檢視ggserr.log的日誌資訊,確認無警告錯誤,啟動pump程式需先啟動target db的mgr程式,否則會報錯無法啟動:

開一個命令列:
cd $OGG_HOME
tail -f 50 ggserr.log

再開一個命令列:
cd $OGG_HOME
./ggsci
GGSCI > info all

GGSCI > start mgr

GGSCI > start exggsdb

GGSCI > start ppggsdb

GGSCI > info all
