I have 10 databases which are configured as principal in mirroring I need to failover all the databases as part of failover , instead of writing query each database as parner failover, is an script which will generate the databases as principal to failover ?
View 3 Replies1. Once fail over to secondary replica, what will happen to connected session in primary node? can the session fail over to secondary seamlessly or need to re-login. what happen committed transactions which has not write to disk.
2. Assume I have always on cluster with three nodes, if primary fails, how second node make write/ read mode.
3. after fail over done to 2nd secondary node what mode in production(readonly or read write).
4. how to rollback to production primary ,will change data in secondary will get updated in primary.
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.
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
Is there any way to trigger an event (ie. call a procedure/job/etc.) when/if an AG fails over?
Not looking to use agent alerts.
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.
View 3 Replies View RelatedI 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:
Is there any single TSQL query which provides below info.When did my AlwaysOn Availability group failed over and from which node it failed to which new node(i.e. replica)?
View 3 Replies View RelatedI have been facing following Error in Failover cluster setup as below. I have prepared 2 node and 2 instance sql server failover cluster on top of windows failover.I have deleted MTCBJINS07 in AD and recreated even after, problem is not solved. MTCBJINS07 is my 2nd sql instance sql server network name.
Cluster network name resource 'SQL Network Name (MTCBJINS07)' failed registration of one or more associated DNS name(s) for the following reason:
DNS bad key.Ensure that the network adapters associated with dependent IP address resources are configured with at least one accessible DNS server.
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?
View 5 Replies View RelatedWe 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.
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
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 ?
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.

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?
If I install an instance with Windows Only authentication, and then change it to Mixed Mode, if I enable the sa login, the password has already been set. What is the default? If it's generated, how secure is it? Is the password generated? What algorithm is used for that?

We are planning to have servers in different subnets so we will be having two ip adresses for listener. How we can point the DNS to the listener ips?

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?

After installing SSMS on some computers - the only way we can get SSMS to run correctly is to run it as the administrator. Is there a way where you don't have to do that? These end users are logging as themselves and have accounts in SQL Server all set up - but SSMS will only launch for them if we right click and select "run as administrator".After doing some digging - it seems that this is a common problem out there.
View 3 Replies View RelatedHave a SQL 2014 install and cannot for the life of me get the maintenance plan to remove old backups. I've tried everything. Rights to the folder where the backups are stored are adequate, extension set in the clean up task is as it should be, etc. Log shows the job ran successfully. Running the command manually shows successful completion, but backups are still not removed.
View 9 Replies View Relatedwhen execute the restore log command, in the messages window it shows how many seconds the restore takes, at the meantime, on the status bar, it also shows the seconds the command takes.
Two values are different and could be very different, please see below examples , restoring takes 1.8 seconds, but in total the command takes 4 seconds to complete, the other one is 8.1 seconds and 12 seconds.
What does SQL Server or Windows do after the restoring?
pic a:
pic b:
I did a xperf, I can see after the restoring is completed, sql server did garbage collect and log write, which just run very quickly, but storage is busy on reading the log file for nearly 2.2 seconds( 4-1.8), and 4 seconds ( 12-8.1) .
pic 1:
pic 2:
see pic 1 above, from 13 to 17, the restore operation is finished, but the storage jump to 100% active to do some reads, only reads no writes. zoom that period shows pic 2, it read 4096 (I don't know the unit size) for about 4 seconds, what does this do?
Data file, log file, backup file are no different drives, but all local drive, the interesting point is the read jumped after restoring, I tested it on different server, same result...
I've got an old version of SQL Server 2008 R2 Developer Edition on an old PC which is failing. I've got a new PC and have put SQL Server 2014 Developer Edition onto it. Now before the old machine completely dies, I've gotten into SSMS on the old machine and did a backup of the databases I want to save. I've moved the .BAK files to where I could get to them from SSMS on the new machine. I've gotten into SSMS and tried to do a restore the database to my new machine. However I'm getting an error that does not make any sense to me.
The database I'm I've backed up is named JobSearch. When I backed it up, that was the only database I had selected. Like I said I copied the .BAK to the new machine. Got into SSMS, told it that I wanted to restore the JobSearch database, telling it where I wanted to put it, and it then immediately fails with a:
"Restore of database 'JobSearch' failed. System.Data.SqlClient.SqlError: Logical file 'VideoLibrary_Data' is not part of the database 'JobSearch'. Use RESTORE FILEISTONLY to list the logical file names."
Well of course VideoLibrary isn't "the logical file". But neither did I select VideoLibrary (which is a database I also want to move, but I'm doing one at a time). So what in heck is going on here? Why is it complaining about a database I haven't even selected to back up? Why, when I check everything on the old machine, it's backing up JobSearch, but on the new machine it sees VideoLibrary?
I am new in SQL Server, What to check ,what action do i need to take while adding a new column to a table.
