Install Goldengate On Oracle Rac 11.2.0.4，goldengate11.2.0.4

安裝環境：

source:OS：redhat 6.3DB:11.2.0.4 racOGG:11.2.1.0.1target:OS:redhat 6.3DB:11.2.0.4OGG:11.2.1.0.1

rac到單機的一個傳輸配置，這裡測試ogg沒有放入到共用儲存中。建議生產環境將ogg放入共用儲存，以免單點故障。

This script installs support for the Oracle GoldenGatemarker system, which is required for DDL support. You will be prompted for the nameof the Oracle GoldenGate schema.2、Run the @ddl_setup.sql script   Script that installs the Oracle GoldenGate DDL extraction andreplication objects. (Oracle installations)3、Run the @role_setup.sql script. This script drops and creates the role needed for DDLsynchronization. It grants DML permissions on the Oracle GoldenGate DDL objects4、Grant the role to all Oracle GoldenGate Extract users. You may need to make multiplegrants if the processes have different user names.Run the @ddl_enable.sql script to enable the DDL trigger.5、To improve the performance of the DDL trigger, make the ddl_pin script part of the databasestartup. It must be invoked with the Oracle GoldenGate DDL user name, as in:@?/rdbms/admin/dbmspool.sqlSQL> @ddl_pin oggTo improve the performance of the DDL trigger This script pins the PL/SQL package that is used by the trigger into memory. If executingthis script from SQL*Plus, connect as SYSDBA from the Oracle GoldenGate home directory.This script relies on the Oracle dmbs_shared_pool system package, so install that packagebefore using ddl_pin.

這裡使用asm時候，需要強調一下， Oracle 10.2.0.5、Oracle 11.2.0.2 版本和後續版本的資料庫中，Oracle 提供了一個新的 ASM API介面 ，可以讓 extract 進程直接利用資料庫伺服器來訪問 redo 和 archive log。使用該 API 後，extract 將獲得一個最大不超過 4 mb 的read buffer。read buffer 越大，對於 redo 量較高的 環境越容易提高 Extract 的進程。可以通過使用 TRANLOGOPTIONS 的 DBLOGREADERBUFSIZE 選項來指定read buffer 的大小。
這種方案只需要在抽取進程的參數中加：

TRANLOGOPTIONS DBLOGREADER

其他版本的方案：
指明asm使用者密碼和歸檔路徑

TRANLOGOPTIONS ASMUSER sys@asm1, ASMPASSWORD oracleTRANLOGOPTIONS ALTARCHIVELOGDEST primary instance test1 /opt/oracle/arch, ALTARCHIVELOGDEST primary instance test2 /opt/oracle/arch

配置tnsnames.ora

ASM1 =  (DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.52)(PORT = 1521))    (CONNECT_DATA =      (SERVER = DEDICATED)      (SERVICE_NAME = +ASM)      (INSTANCE_NAME= +ASM1)    )  )

並且兩個節點的歸檔需要用nfs映射。

這裡資料庫版本是11.2.0.4，所以採用方案一
