SQL Server Admin 2014 :: Manual Failover Of HA Nodes Not Functioning

Jun 29, 2015

I have 3 node HA set up:

-MS Server 2012 R2.
-SQL 2014 EE.
-All windows updates.
-Clean install of both OS and SQL, all 3 nodes are identical.
-SQL Server is running on an alternate port, which I've opened in the firewall. Connections from all network locations are working swimmingly; including connections between all 3 nodes.
-I've got the groups up and running; Listener is set up correctly. Connections work great.
-One node is synchronous, one is asynchronous. Both show synchronized, and synchronizing respectively.
-Data added at the primary node is moved across to all 3 with lightning speed.

When I attempt a manual failover it hangs..and hangs...then pops up an error 41131 and rolls back the failover. Leaving the cluster perfectly intact and working just as it did prior to the failover attempt. What I've checked so far:

-There is absolutely NOTHING in the cluster events log.
-Windows event log shows no errors, just the standard stuff of the primary nodes state changing from primary to resolving and then back again.
-SQL Event log has a few things in there, but nothing that's leading me to a solution, I've attached the log from start to finish on an attempted manual failover:

SQL Server Admin 2014 :: Manual Failover Availability Group

Dec 24, 2014

Recently after turning on trace I restarted the sql services on a box which is configured for automatic failover availability groups. The ag has not failed over to other node. The other node was in resolving state. When the restarted server is back, the AG went back to that server. I checked the sys.availability groups field for failover property failure condition level, it's set to 1 which means service restarts should initiate the failover.

Apr 12, 2015

I'm looking at installing 2008R2 and 2014 side by side, then using Mirroring to provide HA for the 2008R2 instance and AoHA for the 2014 instance. I'd be using the same two physical servers for both the Mirroring pair and the AoHA pair.

SQL Server Admin 2014 :: Window Failover Cluster

Jul 21, 2015

I have installed 2 node windows Fail-over clusters successfully. But QUARUM Configuration is not appearing in Failover cluster manager instead "Witness: Disk (Disk Cluster 4)". I have also configured quarum configuration from Quarum "Configure Cluster QUARUM Settings". I have attached the snapshots of windows cluster configuration. Is it the issue or not. I have not got any warning and error during cluster validation while installing Windows failover cluster. I am assuming it is okay and i can move ahead to installation of SQL Failover cluster setup.

Products used for installation in Virtual Machine:
Windows Server 2012 R2
SQL Server 2012 R2
Note: Service Pack is not installed.

SQL Server Admin 2014 :: Cannot Failover AG To Secondary Replica

Aug 11, 2015

We are not able to failover the AG to secondary replica. The process gets timed out and AG goes to resolving mode. Had to reboot the box in order to switch the AG back to primary node. We even rebuilt the whole AG from scratch but the issue remains.

Failed to bring availability group 'xxxx' online. The operation timed out. Verify that the local Windows Server Failover Clustering (WSFC) node is online. Then verify that the availability group resource exists in the WSFC cluster. If the problem persists, you might need to drop the availability group and create it again. [SQLSTATE 42000] (Error 41131). The step failed.

Not much information is available in the logs.

Version : sql server 2014 sp1

SQL Server Admin 2014 :: AG Failover To Async Node - Replication

Sep 29, 2015

if for any reason AG fails over to async node, how replication behaves? As data will not be in sync with previous primary replica, how replication will work? I think that we have to reset replication from scratch as there's a high chance subscribers might be more updated than current primary replica as failover to this node causes data loss. How to keep replication in sync without resetting up? Can we achieve this?

SQL Server Admin 2014 :: AlwaysOn HA - Database Stuck In Initializing After Failover

Oct 23, 2015

We had to failover our primary db server for maintenance to our secondary replica. The primary was rebooted during maintenance. We failed back after the maintenance and one of the databases is not synchronizing.

I checked sys.dm_hadr_database_replica_states, and it is showing that it is INITIALIZING.

It has been in this state for more than 45 mins now. The last_sent_time, last_received_time, last_hardened_time and last-redone_time are all stuck with a time stamp 45 mins ago.

They haven't changed. How do i resume this database and bring it back in sync?

I tried suspending and resuming the data movement, but hasn't worked.

SQL Server Admin 2014 :: Read Only DNS Listener Failover Automation From Primary To Secondary

Mar 23, 2015

I have a 2 node cluster with 2 standalone 2k14 instances having alwayson setup. As per client requirement we have created a client access point with a cname alias in dns to connect to secondary replica. Now, everytime whenerver the roles switch over one has to manually move this resource from the previous secondary node to the new secondary node. This is tedious, and should not be done manually either, so I am looking for a way to automate it so that as soon as the role switches over, the resource group after some time should also switch over to the current secondary.

Env details
xa (current primary)
y2a (secondary)

client access point (resource group): aglreadtest

SQL Server Admin 2014 :: Handling AlwaysOn Failover And Failback To Preferred Node?

Aug 25, 2015

I am running SQL 2014 2-node AlwaysON Availability groups, Enterprise Edition in our environment and 5 databases are part of AG.

Question is, sometimes AG is getting failed over to node2 but always our preferred node is node1 due to some business needs otherwise some of our jobs will fail.

So, what I looking for is, a sql script which can handle a situation wherein, for some reason, AG is failed over to node2, it should be able to detect if node1 is back online or not and if so, it should fail back to node1. How to do this using tsql query or stored proc or sql agent job ?

Mirroring :: Manual Failover Did Not Get Back Database On Secondary Server?

Jun 22, 2015

I have SQL Server 2008 R2 database mirroring setup with witness. Below database connection string is used by the application
 
jdbc:sqlserver://<Server_A>MSSQLSERVER;databaseName=<Mirrored_DB>;port=1433;failoverPartner=<Server_B>MSSQLSERVER
 
During some maintenance activity at the OS side , I tried to manually failover database from Server_A to Server_B. It took long time for failover  to Server_B. While failing over the Mirrored_DB database goes in In Recovery status and application is not able to connect to database. I waited for long time more than 40 mins for database to come online on Server_B but it did not work.So I have recovered database on Server_B using RESTORE DATABASE Mirrored_DB WITH RECOVERY.
 
After database was recovered on Server_B application was not able to connect to database with error as "The database <Mirrored_DB> on server Server_BMSSQLSERVER is not configured for database mirroring".
 
My Question is

Why manual failover did not get back database on secondary server upwhy the original  connection string below is not able to connect to the database while database is online on Server_B  but without mirroring

 jdbc:sqlserver://<Server_A>MSSQLSERVER;databaseName=<Mirrored_DB>;port=1433;failoverPartner=<Server_B>MSSQLSERVER

SQL Server Admin 2014 :: Does Security-admin Role Plus Deny Alter Any Login Cancel Each Other Out

Aug 27, 2015

I want to set up a database role so that users can use sp_readerrorlog through SSMS. It does a check on membership in the securityadmin role.

I have tested it and can see you can grant execute on xp_readerrorlog but the SSMS GUI uses sp_readerrorlog.

I thought I could create a user/certificate and add the signature to sp_readerrorlog but it's not permitted (likely because it's not a normal database object).

So the other solution is to add the users to the securityadmin role but then explicitly deny alter any login (best done with a custom server role in 2012+ but otherwise just manually in 2008). I tested this out and it works, I'm not able to alter any logins or increase my own permissions, I also did a check of what's reported from fn_my_permissions(null, null) and it shows minimal permissions like I'd expect.

SQL 2012 :: Renamed Failover Nodes For Cluster And Broke It

Apr 17, 2014

I had a cluster running on 3 nodes (windows failover cluster) with server 2012 and SQL server 2012 running in the cluster. Well, I thought I'd just go ahead and rename all 3 of the hosts with new hostnames and it apparently broke the cluster pretty bad. Now when I open failover cluster manager I cannot see anything nor can I connect to the cluster object in AD. I re-named all of the hosts back to their original names but that didn't work.

SQL Server Admin 2014 :: BCP Aborts On First FK Violation

Sep 26, 2013

I want to use BCP to load data from a text file.

By default, constraints are turned off in bcp, so I use the CHECK_CONSTRAINTS hint.

bcp aborts if ANY of the rows contains a FK violation. No data get loaded.

So if I add the -b 1 batch size option, it loads all data UNTIL the first FK violation, but nothing after that.

I want to load EVERYTHING ... except for the violations. But bcp won't let me. Is there a way?

SQL Server Admin 2014 :: DB Read Only Copy

Dec 11, 2014

What is the best approach for a read only copy of a database that is ~ 1TB. The primary database is fed nightly with an ETL process. We are currently trying to duplicate the ETL to read only server but that process is not going well. So we are looking at other options to let SQL make the copy.

The primary database is on a Win12R2 with SQL 12 or 14, a 2 node A/P failover cluster.

The read only copy will be on a Win12R2 with SQL 12 or 14. It is not a requirement to fail over to the read only copy if the primary should go down.

What would best the approach to accomplish the end result?
