distribution 分发数据库 灾难恢复 备份恢复

参考:

http://www.sqlservercentral.com/articles/replication/117265/

前提：

    准备一台电脑，主机名和以前的分发数据库一致。并且安装sql server

 

恢复步骤：

在新的distribution服务器上

1.配置distribution，增加之前的publisher

2.使用备份还原distribution数据库

3.创建job，主要是快照agent和logreadagent，可以从老的distribution直接复制

3.修改发布服务器属性

  exec sp_changedistpublisher  'testsyncdbserv', 'active', 'true' 

4.修改[mspublisher_databases]中的publisher_id为publisher服务器在sys.servers中的server_id

update t  set t. publisher_id  = 2  from dbo.[mspublisher_databases]  t where id=2   

5.修改[mspublications]中的publisher_id为publisher服务器在sys.servers中的server_id

update t set t. publisher_id  = 2 from dbo.mspublications  t where publication_id=2

6.修改[msdistribution_agents]中的publisher_id为publisher服务器在sys.servers中的server_id,subscriber_id为订阅服务器在sys.servers中的server_id，如果没有订阅的可以直接创建。

 exec master.dbo.sp_addlinkedserver @server = n'testsyncrptserv', @srvproduct=n'sql server'
 exec master.dbo.sp_addlinkedsrvlogin @rmtsrvname=n'testsyncrptserv',@useself=n'true',@locallogin=null,@rmtuser=null,@rmtpassword=null
 update dbo.msdistribution_agents set publisher_id=2,subscriber_id=3 where id = 4

7.修改[mssubscriptions]中的publisher_id为publisher服务器在sys.servers中的server_id,subscriber_id为订阅服务器在sys.servers中的server_id，如果没有订阅的可以直接创建。

update dbo.mssubscriptions  set publisher_id =2,subscriber_id=3 where publication_id=2

8.修改logreadagent，snapshotagent的publish_id和对应的job信息

 update [mslogreader_agents]  set publisher_id =2  where id = 2
 update [mssnapshot_agents]  set publisher_id =2  where id = 2
 update t
  set t.job_id = sj.job_id, t.job_step_uid = sjs.step_uid
 from dbo.mslogreader_agents t
  left join dbo.msreplication_monitordata   sm on sm.agent_name = t.name
  left join msdb.dbo.sysjobs sj  on sj.name = t.name
  left join msdb.dbo.sysjobsteps sjs on sj.job_id = sjs.job_id and sjs.step_id = 2
 update t
  set t.job_id = sj.job_id, t.job_step_uid = sjs.step_uid
 from dbo.[mssnapshot_agents] t
  left join dbo.msreplication_monitordata   sm on sm.agent_name = t.name
  left join msdb.dbo.sysjobs sj  on sj.name = t.name
  left join msdb.dbo.sysjobsteps sjs on sj.job_id = sjs.job_id and sjs.step_id = 2
 

在发布上运行

修改发布数据库中的syspublications，syssubscriptions中job的id

update [dbo].[syspublications] set snapshot_jobid=0xd2e257afd287304ca2fc14f3d7c1aecf
update [dbo].[syssubscriptions] set distribution_jobid=0x0e79d3a2a36f73409db3f4261723f37a
