Error 1474 Sql Server
a Hyper-V virtualised mirror on Windows 2008 R2 Datacentreand a witness running SQL Express on Windows 2008 Standard. All are an error occurred in a service broker/database mirroring transport connection endpoint at 10.0.5512and 64bit. I am using High Safety with automatic failover (synchronous) mirroring on37 databases. All servers have 1GB network links and are 1ms away from each other. Since early January, approximately once to twice error 3041 severity 16 state 1 a dayI see all the databases suddenly throw error 1479: Error: 1479, Severity: 16, State: 1. Database mirroring is inactive for database 'xxx'. This is an information message only. No user action is required. The mirroring connection to "TCP://MIRROR.DOMAIN.com:5022" has timed out for database "xxx" after 10 seconds without a response. Check the service and network connections. Within a few seconds, usually less than 10 I see another entry:
Error 17054 Severity 16 State 1
Starting up database 'xxx'. Then a bunch of recovery messages, usually 0 transactions rolled back. Then a CHECKDB which finishes without errors then: Database mirroring is active with database 'xxx' as the principal copy. This is an informational message only. No user action is required. This happens for all databases that are mirrored and usually takes less than 20 seconds for the entire process. There are no other error codes shown, except some 18456 where users have tried to access during the time the databases are unavailable. I have a lock detector programrunning against the principalthat shows queries stuck waiting on DBMIRROR_DBM_EVENT waits, and sometimes on DBMIRROR_WORKER_QUEUE. I have tried moving the mirror to different switches and am fairly sure the network is fine as no other machines are interrupted in the same way, but I can't rule it out. Looking at performance monitor on the mirror, during these incidents I see a spike (20 or 30 times higher than usual) in Processor Queue Length, % Disk Read Time, Page Faults/sec, and big increases (5-10 times higher than usual) in Current Disk Queue Length and Processor time. Available memory does not seem to increase or decrease at all. Can anyone suggest what might be happenin

we will do reindexing and the file size will be !10 - 12 GB. and it's tkaing more time to synchronize the files between the mirroring and https://social.msdn.microsoft.com/Forums/sqlserver/en-US/7dbc9d30-5c63-4141-856e-6316d9d8ccbb/mirroring-failing-with-error-1479-for-all-databases-at-once?forum=sqldatabasemirroring principal server. and also our lan is about 1 GB speed,and it's using max 1 percent only. If i look into the mirroing history log, is the send rate is higher , the time to send the log is very low. or else it's higher.i am confused about the bottle neck here.I am thinking the network http://www.sql-server-performance.com/forum/threads/database-mirroring-error-error-1479-severity-16-state-2.30671/ is the bottle neck.is there a way i can isolate the problem. any help will be appreciated. thanks priyaram, Aug 3, 2009 #2 arunyadav Member Check if this could help DB Mirroring 1479 arunyadav, Aug 3, 2009 #3 (You must log in or sign up to reply here.)

follows: A B C mirror to witness a WEB client Broken network fault simulation: The A network is broken, http://www.programering.com/q/MjN2EDMwATM.html found that B becomes subject (but the show has been disconnected), https://www.experts-exchange.com/questions/28458329/SQL-Server-Mirroring-Connection-Issue.html but the WEB client can not access (even wait 10 minutes, empty the application pool, restart the site too), only when the recovery of A network, B became a real subject can be accessed (WEB then the A can access). Why wait for severity 16 the recovery of A network, B can be accessed? PS: can be a few seconds to switch the past if you use the ALTER DATABASE ImageTest SET PARTNER FAILOVER.

Solved SQL Server Mirroring Connection Issue Posted on 2014-06-18 MS SQL Server 2008 Windows Server 2008 1 Verified Solution 1 Comment 1,092 Views Last Modified: 2014-06-19 I have a very odd problem. I have two HP ProLiant servers both running Windows Server 2008R2 and SQL Server 2008R2. Server A is the primary mirror and server B is the backup. This morning an issue with the AC necessitated shutting down both of these machines for awhile. After they came up and were working OK, I noticed that the mirroring could not be re-established. On server A, I am getting the following errors: Database mirroring connection error 4 '64(The specified network name is no longer available.)' for 'TCP://serverB:5022'. Error: 1474, Severity: 16, State: 1 Select all Open in new window On server B, I am getting the following errors: The mirroring connection to "TCP://serverA:5022" has timed out for database "DB" after 10 seconds without a response. Check the service and network connections. Error: 1479, Severity: 16, State: 1. Select all Open in new window I can ping the servers using both the name and the IP address from each other and from other workstations. Other workstations can connect to either server and access data. I have tried telneting both ways on port 5022 and have no problems. I have reset server B but I cannot reset server A until after hours. Database aware applications on server B will not connect to server A either. I have disabled anti-virus and firewalls already but the problem persists.
