ogg BR – BOUNDED RECOVERY 测试案例

首先，我们来看两个OGG同步中可能的问题：

l oracle在线日志包含已提交的和未提交的事务，但OGG只会将已提交的事务写入到队列文件。因此，针对未提交的事务，特别是未提交的长事务，OGG会怎样处理呢？

l 有些长事务是在批处理作业中，需要几个小时才能执行完成，比如晚上跑批的作业。OGG在解析过程中，会从这些事务一执行就开始读取在线日志，但这些事务可能会持续很久，
这期间，在线日志可能会切换到归档日志，同时这期间也会有其它事务在执行和提交，如果长事务一直未提交，归档日志又因为定期的rman备份而删除，OGG将如何处理？

针对以上情况，OGG有2种处理方式，
第一种就是使用正常恢复归档的方式，即恢复OGG需要的所有归档日志，可能是从长事务开始的那个归档开始，
这样OGG将从事务开始的检查点开始解析；

第二种方式就是使用Bounded Recovery的方式，下面的内容将讨论这种方式。

简单来说，BR（Bounded Recovery ）默认的设置是4小时，即每4小时OGG抽取进程会做一个检查点，在每个检查点的时间点上，
OGG会检查长事务，并将超过4小时的长事务的状态写入到磁盘（如果没有达到4小时，则此事务不会被BR写入），
默认保存在OGG安装目录的BR目录下。在每个BR的间隔点，这个操作会一直持续，直到事务提交，或事务回滚。

下面的示例中，我们设置BRINTERVAL为20分钟：

BR BRINTERVAL 20M

下面是针对BR的官方文档描述：

使用磁盘持久保存数据，用于恢复长事务，让抽取进程可以确保捕获性能（虽然只有在极端情况下才会发生捕获延迟）。
如果抽取进程停止时，有些事务的开始时间远在这个时间点之前，那么系统需要占用大量的日志空间，也有可能这些日
志文件不在磁盘上或已被删除。而且，重新从一个很早的日志文件开始读取事务，这种做法是不可接受的，因为这些
日志文件中的其它事务已经被解析并被写入到队列文件。

如果通过持久化数据能恢复这些长事务的状态，那么就可以消除这个往返读取的动作。极端的情况下，如果有多个长事务，
如果每个事务都要求从起点重新读取，那么OGG的捕获性能将大大降低。

在本示例中，我们将BR的间隔设置为20分钟，然后执行一个insert语句，但不提交。
此时，抽取进程会从在线日志的某个点开始读取，在线日志的序号为：#。

然后我们切换几组日志，备份并删除序号为14878的日志文件。我们可以看到每隔20分钟，BR checkpoint就会执行，
此时，长事务的状态信息及数据就会被写入到磁盘上。即使磁盘上没有对应的归档日志文件，抽取进程也不会再去读取这些日志，
而是直接从磁盘上保存的BR数据中进行恢复，如果事务提交，则OGG会直接将BR目录下的数据写入到队列中。 

测试步骤如下：

执行下面的INSERT语句，但不提交，用于测试长事务的场景：

SQL> insert into myobjects

select object_id,object_name,object_type from dba_objects;
 rows created.

通过infor ext1检查当前读取的在线日志序号，本测试中是14878

大约20分钟之后，我们继续使用showch，看看与前面的命令相比，输出有哪些差异：
可以看到，当前读取的在线日志序号已经变为14884（以前是14878）。
但恢复检查点仍然没有变化，与上一个命令执行结果相同。

通过上面的命令，我们看到了BR检查点的相关信息，前面我们把BR间隔从默认4小时改为20分钟，因此，每隔20分钟
（本示例中是：:，:，:...），长事务当前的状态信息会被抽取进程写入到磁盘上的BR目录。
因此，我们看到在18:27的BR间隔时间点，BR将在线日志14881的信息持久到磁盘上，如果这个时候extract有错误或重启，
extract不再需要从早于14881序号的redo或归档里读取数据。

此时，如果我们删除14878的归档日志会怎样呢？因为BR检查点已经将包含长事务的日志序号为14878的信息写入到磁盘，
extract进程将不再需要这些旧的归档文件。为了测试这个功能，我们将14878归档备份之后删除，
记住，这个序号是长事务开始时的序号，在抽取进程检查点日志中有记录。

在抽取进程ext1的日志报告中，可以看到有长事务的信息、BR检查点的信息，而且每隔20分钟，
BR检查点写入的redo日志序号是在增长的，即OGG抽取进程每20分钟会将当前日志序号写入，同时在OGG日志报告中体现出来。

首先，我们来看两个OGG同步中可能的问题：

l oracle在线日志包含已提交的和未提交的事务，但OGG只会将已提交的事务写入到队列文件。因此，针对未提交的事务，特别是未提交的长事务，OGG会怎样处理呢？

l 有些长事务是在批处理作业中，需要几个小时才能执行完成，比如晚上跑批的作业。OGG在解析过程中，会从这些事务一执行就开始读取在线日志，但这些事务可能会持续很久，
这期间，在线日志可能会切换到归档日志，同时这期间也会有其它事务在执行和提交，如果长事务一直未提交，归档日志又因为定期的rman备份而删除，OGG将如何处理？

针对以上情况，OGG有2种处理方式，
第一种就是使用正常恢复归档的方式，即恢复OGG需要的所有归档日志，可能是从长事务开始的那个归档开始，
这样OGG将从事务开始的检查点开始解析；

第二种方式就是使用Bounded Recovery的方式，下面的内容将讨论这种方式。

简单来说，BR（Bounded Recovery ）默认的设置是4小时，即每4小时OGG抽取进程会做一个检查点，在每个检查点的时间点上，
OGG会检查长事务，并将超过4小时的长事务的状态写入到磁盘（如果没有达到4小时，则此事务不会被BR写入），
默认保存在OGG安装目录的BR目录下。在每个BR的间隔点，这个操作会一直持续，直到事务提交，或事务回滚。

下面的示例中，我们设置BRINTERVAL为20分钟：

BR BRINTERVAL 20M

下面是针对BR的官方文档描述：

使用磁盘持久保存数据，用于恢复长事务，让抽取进程可以确保捕获性能（虽然只有在极端情况下才会发生捕获延迟）。
如果抽取进程停止时，有些事务的开始时间远在这个时间点之前，那么系统需要占用大量的日志空间，也有可能这些日
志文件不在磁盘上或已被删除。而且，重新从一个很早的日志文件开始读取事务，这种做法是不可接受的，因为这些
日志文件中的其它事务已经被解析并被写入到队列文件。

如果通过持久化数据能恢复这些长事务的状态，那么就可以消除这个往返读取的动作。极端的情况下，如果有多个长事务，
如果每个事务都要求从起点重新读取，那么OGG的捕获性能将大大降低。

在本示例中，我们将BR的间隔设置为20分钟，然后执行一个insert语句，但不提交。
此时，抽取进程会从在线日志的某个点开始读取，在线日志的序号为：#14878。

然后我们切换几组日志，备份并删除序号为14878的日志文件。我们可以看到每隔20分钟，BR checkpoint就会执行，
此时，长事务的状态信息及数据就会被写入到磁盘上。即使磁盘上没有对应的归档日志文件，抽取进程也不会再去读取这些日志，
而是直接从磁盘上保存的BR数据中进行恢复，如果事务提交，则OGG会直接将BR目录下的数据写入到队列中。 

测试步骤如下：

执行下面的INSERT语句，但不提交，用于测试长事务的场景：

SQL> insert into myobjects

select object_id,object_name,object_type from dba_objects;
75372 rows created.

通过infor ext1检查当前读取的在线日志序号，本测试中是14878

T27, T45开始于BR N-1之前，会在BR N这个检查点上记录状态；而T801是在BR N-1之后开始，在BR N检查点时，由于不满足BR interval的时间要求，因此不会被记录到BR N这个检查点上，而是会记录在BR N+1这个检查点上。
一旦在BR N和BR N+1这个时间范围内，extract当掉，则T801的所有信息丢失，重启extract之后，将会从T801开始的时间点解析日志。
