distribution 分發數據庫 災難恢復 備份恢復

參考:

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

前提：

    準備一臺電腦，主機名和之前的分發數據庫一致。而且安裝sql server

 

恢復步驟：

在新的distribution服務器上

1.配置distribution，增長以前的publisher

2.使用備份還原distribution數據庫

3.建立job，主要是快照agent和logreadagent，能夠從老的distribution直接複製

3.修改發佈服務器屬性

  EXEC sp_changedistpublisher  'TESTSYNCDBSERV', 'active', 'true' 

4.修改[MSpublisher_databases]中的publisher_id爲publisher服務器在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爲publisher服務器在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爲publisher服務器在sys.servers中的server_id,subscriber_id爲訂閱服務器在sys.servers中的server_id，若是沒有訂閱的能夠直接建立。

 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爲publisher服務器在sys.servers中的server_id,subscriber_id爲訂閱服務器在sys.servers中的server_id，若是沒有訂閱的能夠直接建立。

update dbo.MSsubscriptions  SET publisher_id =2,subscriber_id=3 WHERE publication_id=2

8.修改logreadagent，snapshotagent的publish_id和對應的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
 

在發佈上運行

修改發佈數據庫中的syspublications，syssubscriptions中job的id

update [dbo].[syspublications] set snapshot_jobid=0xD2E257AFD287304CA2FC14F3D7C1AECF
update [dbo].[syssubscriptions] set distribution_jobid=0x0E79D3A2A36F73409DB3F4261723F37A
