【OGG】关于在一套复制环境中使用不同版本OGG的问题

1.源头OGG版本低,目的端OGG版本高,此种配置不需要做任何的额外改动.跟两端是相同OGG版本的同步是完全一样的参数设置.

2.源头OGG版本高,目的端OGG版本低,此种配置需要在源头的抽取进程和传输进程的参数文件中设置trailfile的格式(设置为跟目的端OGG版本一样的格式).

EXTTRAIL <trail file>, FORMAT RELEASE 10.0

RMTTRAIL <trail file>, FORMAT RELEASE 10.0

注意:此处的10.0是目的端OGG的版本号.

3.源头的抽取进程和传输进程的参数文件中务必都要设置trailfile的格式.因为,仅仅依靠传输进程无法达到转换trailfile格式的目的.因为传输进程就是这么设计的:It must write trails in the same version it read them.

Can OGG Version 11 Be Used to Pump/Move Trails Generated from Version 9 or 10? (文档 ID 1297283.1)  
 

In this Document

APPLIES TO:

Oracle GoldenGate - Version 11.1.1.0.0 and later  
Information in this document applies to any platform.  

GOAL

Can Oracle GoldenGate version 11 Extract be used to pump/move trail files which were generated from version 9 or 10 to another server?

SOLUTION

Oracle GoldenGate version 11.1 can read versions 9 and version 10 trail files but it can not write them in a different format (version 11.1) than the version of the trail being read. It must write trails in the same version it read them. The extract can be forced to write a trail in a particular version format by using the FORMAT RELEASE option.

Example:

RMTTRAIL <trail file>, FORMAT RELEASE 10.0
