sqlserver distribution分发alwayson搭建

CREATE AVAILABILITY GROUP [dis_awo]
WITH (AUTOMATED_BACKUP_PREFERENCE = SECONDARY,
DB_FAILOVER = OFF,
DTC_SUPPORT = NONE)
FOR DATABASE [distribution]
REPLICA ON N‘TEST177‘ WITH (ENDPOINT_URL = N‘TCP://TEST177.Test.com:5022‘, FAILOVER_MODE = AUTOMATIC, AVAILABILITY_MODE = SYNCHRONOUS_COMMIT, BACKUP_PRIORITY = 50, SECONDARY_ROLE(ALLOW_CONNECTIONS = ALL)),
    N‘TEST178‘ WITH (ENDPOINT_URL = N‘TCP://TEST178.Test.com:5022‘, FAILOVER_MODE = AUTOMATIC, AVAILABILITY_MODE = SYNCHRONOUS_COMMIT, BACKUP_PRIORITY = 50, SECONDARY_ROLE(ALLOW_CONNECTIONS = ALL));

TEST178上联结可用组，监听器： dis_ip ,distribution alwayson完成。

TEST177上agentjob TEST125-test-1 生成脚本，在TEST178上执行。

修改点：

@command=N‘-Publisher [TEST125] -PublisherDB [test] -Distributor [dis_ip] -DistributorSecurityMode 1  -Continuous‘, 

TEST177上agentjob TEST125-test-Repl_test-TEST129-3  生成脚本，在TEST178上执行。

修改点：

@server=N‘TEST178‘, 

@command=N‘-Subscriber [TEST129] -SubscriberDB [test] -Publisher [TEST125] -Distributor [dis_ip] -DistributorSecurityMode 1 -Publication [Repl_test] -PublisherDB [test]    -Continuous‘, 

TEST177/178建立主辅启动job。

declare @role_desc varchar(50)
select @role_desc=a.role_desc from sys.dm_hadr_availability_replica_states a
join sys.dm_hadr_availability_replica_cluster_states b on a.replica_id=b.replica_id
where b.replica_server_name=@@SERVERNAME
if @role_desc=‘PRIMARY‘
begin 
exec sp_start_job @job_name=‘TEST125-test-1‘
exec sp_start_job @job_name=‘TEST125-test-Repl_test-TEST129-3‘
end 
else 
begin 
exec sp_stop_job @job_name=‘TEST125-test-1‘
exec sp_stop_job @job_name=‘TEST125-test-Repl_test-TEST129-3‘
end

过程完成。

此方法，对自己没有信心就不要使用，之后复制监控器界面将不再可用，只能通过脚本进行监控复制订阅。

PS：

在整个搭建测试的过程中，本着哪里不通改哪里，最后测试成功，以上是简化的方法。

过程中其他用到的脚本：

exec sp_helpdistpublisher N‘TEST125‘

sp_changedistpublisher @publisher = ‘TEST125‘
     ,  @property =  ‘active‘ 
    ,  @value = ‘true‘ 

select datasource, srvid from master..sysservers where upper(srvname) = upper(N‘TEST125‘)

select datasource, srvid from master..sysservers where upper(srvname) = upper(N‘TEST129‘)

select * from MSdistribution_agents
