GoldenGate Capture捕捉

• Log-based change data capture
– High volume
– Low overhead

• Decoupled architecture
– Multiple capture processes may be used to scale, but generally
not required
– Possible to split “hot” tables into a separate capture process

• Filtering and Compression
– Unnecessary change data if discarded immediately
– U d t and d l t are “
Updates d deletes “compressed” b d f lt
d” by default
– Before images are discarded by default

GoldenGate Delivery传送

• Decoupled architecture
– Multiple delivery processes may be used to scale
– Possible to split “hot” tables into a separate delivery process
– Possible for multiple delivery p
p y processes to split the work for a single
p g
table

• T
Transaction grouping
ti i
– Small transactions are grouped by default to reduce commit overhead

GoldenGate初始化

开箱即用的转换能力

• Data selection and filtering数据选择和过滤

• Column mapping列映射

• Functions函数功能

数据的选择和过滤
• GoldenGate provides the ability to select or filter out data based on a
variety of levels and conditions

Parameter Clause Selects

TABLE or MAP –— Table
WHERE Row
FILTER Row, Operation
Row Operation, Range

TABLE COLS | COLSEXCEPT Columns

列映射
• GoldenGate provides the capability to map columns from one table to another

• Data can be transformed between dissimilar database tables

• Mapping can be applied either when extracting or replicating data

This example uses special values to build history of operations data

INSERTALLRECORDS
MAP SALES.ACCOUNT, TARGET REPORT.ACCTHISTORY,
COLMAP (USEDEFAULTS,
TRAN_TIME = @GETENV(“GGHEADER”,”COMMITTIMESTAMP”),
OP_TYPE = @GETENV(“GGHEADER”, “OPTYPE”),
_
BEFORE_AFTER_IND = @GETENV(“GGHEADER”,
“BEFOREAFTERINDICATOR”),
);

Functions函数功能
• GoldenGate provides the capability to transform columns by using a set of built-
in functions (currently 35)
• Transformation functions can be applied either for Extract or Replicat
• If you require more, you also have the ability to call your own logic through user
exits

MAP SALES.ACCOUNT, TARGET REPORT.ACCOUNT,
COLMAP ( USEDEFAULTS,
TRANSACTION_DATE = @DATE (“YYYY-MM-DD”,
“YY”, YEAR,
YY ,
“MM”, MONTH,
“DD”, DAY),
AREA_CODE = @STREXT (PHONE-NO, 1, 3),
PHONE_PREFIX = @STREXT (PHONE-NO, 4, 6),
PHONE_NUMBER = @STREXT (PHONE-NO, 7, 10) );

 优点：可以通过SAN来完成数据同步，速度较快，对存储无特定要求。
 缺点：大多与基于存储的方案相同，另外这种方案需要额外的磁盘空间。
基于数据库  其核心是把数据库的日志传送到远端数据库，通过数据库的恢复机制将数据恢复出来。如
的恢复 O l 的 D t Guard 和DB2的HADR
Oracle Data G d 和DB2的HADR。
优点：方法简单，对存储没有特别要求，过程对应用可见，可随时观测到已经恢复的数据，可
避免逻辑坏块。
缺点：对数据库之间的版本要求比较高，不能跨平台，对网络带宽有一定的要求。
逻辑方式  通过外围应用来实现，实现方法如 GoldenGate.
 优点：方法简单，实时性强，灵活性强，跨平台，可以忍受苛刻的网络条件。
 缺点：有一定的维护成本。

Oracle GoldenGate 实施经验分享 (检查操作系统及数据库）

Oracle GoldenGate 检查操作系统及数据库
 如果操作系统是AIX 5.3，须确保 xlC/C++ 的版本是9.0或者以上.
 如果源数据库的版本是9iR1或者9iR2，确保参数_log_parallelism或者
log_parallelism 的值为1.
 确认源数据库处于归档模式可用命令 archive log list查看
确认源数据库处于归档模式， list查看.
 确认源数据库undo_retention的值足够大，undo tablespace的空间足够多.
 确认源及目标数据库的open_cursors值足够大.
 检查源库redo log的 Thread 数目.
 支持DDL：如果数据库的版本是10gR1，将_recyclebin设置为false；如果数据库的
版本是10gR2或者以上，将recyclebin设置为off.
版本是10gR2或者以上将recyclebin设置为off

Oracle GoldenGate 实施经验分享 (数据初始化)

方法优点/缺点
EXP/IMP  这种方法的好处是，可以通过管道直接将数据导入到目标
数据库，这样做不需要额外的磁盘空间来存放导出文件。
 缺点：比较慢。
DATA PUMP  优点：导出与导入速度都非常快。
缺点：在源端及目标端都要有足够的空间来容纳导出文件，
且需要将导出文件传送到目标端。

Transportable Tablespace  优点：导出速度快，使用RMAN TRANSPORT
(TTS) TABLESPACE并不需要将表空间置为read only.
缺点：目标端的数据文件大小需要与与源端一致。
缺点：目标端的数据文件大小需要与与源端致。

RMAN  优点：导出速度快，适合整库导出.
缺点如果数据库的版本是10 以下不支持跨平台源端
缺点：如果数据库的版本是10g以下，不支持跨平台；源端
与目标端数据库版本一致，目标端只能通过数据库升级来升到
高版本。
