小编给大家分享一下OGG如何安装,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!
1、 主库OGG安装
说明:数据库版本为10.2和11.2.0.3可以用goldengate11.2版本,数据库版本为11.2.0.4和12C,需要使用goldengate12.1版本,否则ddl_setup.sql脚本报错,修改数据库goldengate相关参数,show parameter goldengate查看,改为true(主备库都要修改)。

打开附加日志并切换日志(保证Online redo log和Archive log一致)
SQL> alter database add supplemental log data ;

SQL> alter database add supplemental log data (primary key, unique,foreign key) columns;

SQL> alter system switch logfile;

回退操作:如果出现问题,可以通过以下语句进行回退:
alter database drop supplemental log data ;
alter database drop supplemental log data

使用以下sql语句检查数据库附加日志的打开状况:

注:确保最小附加日志,pk,uk,fk附加日志打开。而all columns的附加日志关闭;
如果all columns的附加日志打开的话,则需要使用以下语句予以关闭:
alter database drop supplemental log data

SQL> Alter database force logging;
Database altered.
注:该模式的打开需要和业务部门进行相关确认和讨论;如果数据库不能打开到force logging的模式下,则no logging的表无法进行同步;
如果需要进行回退,关闭强制日志模式,请使用以下sql:
Alter database no force logging

OGG的DDL对象安装时不能有运行的sessoin存在,请DBA执行停机清理或者杀死所有数据库中的Session。
建议有条件先执行停止业务,并关闭Oracle的Listener。
注:时间大约需要30分钟左右,在这段时间内,需要完成2.9小节的所有操作步骤。此后的所有步骤,都可以在业务正常运行时进行操作。

在数据初始化的过程中,不需要源数据库停机。
1) 源端和目标端安装OGG软件,并启动manager
2) 源端配置OGG的Extract及DataPump
3) 源端启动Extract进程,并且人工记录抽取进程启动的时间点,例如:“2011-05-03
11:20:55” ,将此时间点作为在下一步中查找长事务的一个判断条件;
4) 长事务处理:在V$TRANSACTION中查找当前正在运行的事务(RAC环境下,查看gv$transaction),并找出相应的长事务。在执行rman备份之前,确保这些长事务已经完成,或者被kill掉(需要得到dba或者相关管理人员的确认)。
Select start_time from gv$transaction where to_date(start_time,
'yyyy-mm-dd hh34:mi:ss')<to_date('2011-05-03 11:20:55', 'yyyy-mm-dd
hh34:mi:ss');
注:通过上面的SQL语句查找到比第3歩中记录下的时间点早的事务,需要等到该事务结束,然后执行rman的备份;

其他:
禁用带有DML操作的JOB
1) 在dba_jobs中,有些job/schedule,会在复制对象中产生DML的操作,必须禁用掉,否则会造成DML语句在目标端的重复执行;
2) 在dba_schedule_jobs中的有些job,会在复制对象中产生DML操作,必须禁用掉,否则会造成DML语句在目标端的重复执行;
注:在目标端恢复的时候,可以在pfile文件中将job_queue_processes设置为0,然后将带有dml的job停掉以后,再修改job_queue_processes参数至正常值,如job_queue_processes=10;

在数据初始化的过程中,不需要源数据库停机。
1) 源端和目标端安装OGG软件,并启动manager
2) 源端配置OGG的Extract及DataPump
3) 源端启动Extract进程,并且人工记录抽取进程启动的时间点,例如:“2011-05-03
11:20:55” ,将此时间点作为在下一步中查找长事务的一个判断条件;
4) 长事务处理:在V$TRANSACTION中查找当前正在运行的事务(RAC环境下,查看gv$transaction),并找出相应的长事务。在执行rman备份之前,确保这些长事务已经完成,或者被kill掉(需要得到dba或者相关管理人员的确认)。
Select start_time from gv$transaction where to_date(start_time,
'yyyy-mm-dd hh34:mi:ss')<to_date('2011-05-03 11:20:55', 'yyyy-mm-dd
hh34:mi:ss');
注:通过上面的SQL语句查找到比第3歩中记录下的时间点早的事务,需要等到该事务结束,然后执行rman的备份;

2) 在dba_schedule_jobs中的有些job,会在复制对象中产生DML操作,必须禁用掉,否则会造成DML语句在目标端的重复执行;
注:在目标端恢复的时候,可以在pfile文件中将job_queue_processes设置为0,然后将带有dml的job停掉以后,再修改job_queue_processes参数至正常值,如job_queue_processes=10;
