GoldenGate Integrated Capture Mode

来源:程序员人生   发布时间:2015-03-31 08:22:29 阅读次数:4467次
    通常我们配置的Goldengate是读取在线日志文件或ALO(只读归档日志的)。还有另外1种抽取模式Integrated Capture Mode,它是依托 logmining server读取数据库改变的信息

    Integrated capture supports more data types as well as compressed data and as it is fully integrated with the database there is no additional setup steps required when we are configuring GoldenGate with things like RAC, ASM and TDE 

配置环境:

Source: OS:Redhat 6.3 DB:11.2.0.4 IP:192.168.56.60 Target: OS:Redhat 6.3 DB:11.2.0.4 IP:192.168.56.61

Prepare(Source And Target DB):

useradd ogg -g oinstall Add Environment Varible vi /home/oracle/.bash_profile export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/ogg Configure Database alter database archivelog; alter database force logging; alter database add supplemental log data (primary key ,unique index) columns; select SUPPLEMENTAL_LOG_DATA_MIN, SUPPLEMENTAL_LOG_DATA_PK, SUPPLEMENTAL_LOG_DATA_UI from v$database; Create OGG User: sqlplus / as sysdba create user ogg identified by ogg; grant dba to ogg; GGSCI (zbdba1) 1> edit params ./GLOBAL GGSCHEMA ogg CHECKPOINTTABLE ogg.checkpoint SQL> show parameter goldengate NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ enable_goldengate_replication boolean TRUE Installing the DDL objects: 1、Run the @marker_setup.sql script. This script installs support for the Oracle GoldenGate marker system, which is required for DDL support. You will be prompted for the name of the Oracle GoldenGate schema. drop trigger ggs_ddl_trigger_before; grant create table,create view,create sequence to ogg; 2、Run the @ddl_setup.sql script Script that installs the Oracle GoldenGate DDL extraction and replication objects. (Oracle installations) 3、Run the @role_setup.sql script. This script drops and creates the role needed for DDL synchronization. It grants DML permissions on the Oracle GoldenGate DDL objects 4、Grant the role to all Oracle GoldenGate Extract users. You may need to make multiple grants 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 database startup. It must be invoked with the Oracle GoldenGate DDL user name, as in: @?/rdbms/admin/dbmspool.sql SQL> @ddl_pin ogg To improve the performance of the DDL trigger This script pins the PL/SQL package that is used by the trigger into memory. If executing this 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 package before using ddl_pin.

在设置TRANLOGOPTIONS INTEGRATEDPARAMS (MAX_SGA_SIZE 100) 参数时,启动可能报错
