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:4479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.
