SQL 2012 :: AlwaysOn Two Secondary Replicas
Apr 14, 2014While configuring SQL Server 2012 Cluster with Always on, why do we need two secondary replicas.
The attached link will describe the actual query. [URL] ....
SQL 2012 :: AlwaysOn - Readable Secondary Option
Aug 21, 2014In always on under availability group server name properties can see the option Readable Secondary. In that for secondary server the Readable Secondary Option is YES and for Primary it is Read-Intent. I believe Read-Intent allows only read only connections and YES allows all user connections.

What exactly it means for the primary and secondary?
SQL 2012 :: AlwaysOn Secondary Replica - Resolving State
May 21, 2013I have an AlwaysOn Availability group configured between 2 nodes (Synchronous)
Automatic failover was working fine until recently
I can failover between the nodes manually but automatic failover doesn't seem to be working. In my earlier test, I would shut down the SQL Service on the primary and within seconds, the secondary replica would take over. Recently I have performed the same test and the secondary replica enters the resolving state and the DB in unavailable.
I have tried everything here: [URL] ....
The only change I made was changing the availability mode from Synchronous to Asynchronous - Could that be the cause?

SQL 2012 :: AlwaysOn Secondary Database In Restricted Mode?
Jun 27, 2015Secondary replica database(setup in async mode) of AlwaysON went in "restricted mode" during weekly reindex operation.
So I have tried below steps
1) Executed following statement on the same secondary replica database where the issue exists
alter database <DBNAME> set multi_user with rollback immediate
but it failed with the error saying "The operation cannot be performed on database "dbname" because it is involved in a database mirroring session or an availability group. Some operations are not allowed on a database that is participating in a database mirroring session or in an availability group. ALTER DATABASE statement failed."
2) Primary database is multi_user but still tried following command on primary replia database(thinking it will replicate)
alter database <DBNAME> set multi_user
but no luck. The secondary alwaysON database shows (synchronizing) as the alwaysON is set in async mode but the command doesn't replicate across secondary
so we are left with the only option to re-setup alwaysON but I want to avoid it as database size is huge..
any other options or am I missing anything?

SQL Server Admin 2014 :: AlwaysOn Secondary Down -> Whole Cluster Goes Down
Oct 25, 2015We had a big issue today during maintenance work in our SQL environment.
So our environment:
- 2x SQL Server 2014 Enterprise on Windows Server 2012 R2 (SRV1 and SRV2)
-- Both Hyper-V VMs on different Hosts
-- Both configured to an Windows Failover Cluster and AlwaysOn Availability Group (AG1)
-- AG Listener: AG1_lis
-- No shared storage (each Hyper-V Host has its own local storage)
-- Asynchronous Mode
-- SRV1 is primary, SRV2 is secondary SQL node
What happened?
- Shutting down Windows on SRV2 due hardware maintenance
- Cluster goes offline, AG1 goes offline
-- Error message: "Stopped listening on virtual network name 'AG1_lis'."
-- Error message: "The availability group database "DatabaseXY" is changing roles from "PRIMARY" to "RESOLVING" because the mirroring session or availability group failed over due to role synchronization."
Results?
- AG1_lis wasn't available for our applications and they stopped working properly because database connection was lost!
I think, I HOPE, this is not the normale behaviour when one node is shutting down (especially the secondary node!)
Recovery :: AlwaysOn DB Going Into Restoring State On Secondary Server
Jun 22, 2015I noticed that after a SQL AlwaysOn failover, one of the DB in the secondary replica is stuck in Restoring state. The primary replica shows that it is in a synchronized state. These are the error logs from SSMS. How do I trace the cause of the problem?
Error: 5901, Severity: 16, State: 1.
Nonqualified transactions are being rolled back in database for an AlwaysOn Availability Groups state change. Estimated rollback completion: 0%. This is an informational message only. No user action is required
Error: 18400, Severity: 16, State: 1.
One or more recovery units belonging to database failed to generate a checkpoint. This is typically caused by lack of system resources such as disk or memory, or in some cases due to database corruption. Examine previous entries in the error log for more detailed information on this failure.
The background checkpoint thread has encountered an unrecoverable error. The checkpoint process is terminating so that the thread can clean up its resources. This is an informational message only. No user action is required.
Recovery :: AlwaysOn Secondary Operational State Unknown
Sep 30, 2013I recently configured SQL Server 2012 AlwaysOn Availability group using two nodes - a primary and one secondary read only replica. The group is residing on a windows 2012 cluster with an smb file share as the quorum. I am able to successfully failover through SQL and through the windows 2012 cluster. When I look at the group dashboard on the primary server and view the Operational state of each node I notice an odd value. The secondary role server is listed as Unknown. I also noticed that the Availability replicas node icons in object explorer are displaying the same icon on the primary server but on the secondary server, the primary server is shown as a server with a question mark.
Am I missing a permissions setting or is this normal behavior.
For example:
ServerA is the primary
ServerB is the secondary
ServerA lists the servers in Object Explorer as:
ServerA (Primary)ServerB (Secondary)
ServerB lists the servers in Object Explorer as:
ServerA ServerB (Secondary)
The primary is never listed a primary on the secondary server. Again failovers are working properly, but I want to be sure I am not missing a setting somewhere.
SQL 2012 :: Failover On 2 Servers AlwaysOn AG With Read-only Secondary Replica
Mar 28, 2014What happens when an automatic failover occurs, in a two server AlwaysOn Availability Group configuration, where the secondary replica is configured as read-only?
Will it only allow read-only connections, or will it become read-write and can accept INSERT, UPDATES and DELETES when assigned the new role as Primary?
Is it correct that adding a third server/node, that just acts as passive and should be used for automatic failover, to support true HADR, would NOT need another license .. and that licenses would only be required for the previous Primary and Secondary (Read-Only) replicas?
SQL 2012 :: VLFs On AlwaysOn Primary Replica After Log Backup From Secondary
Aug 6, 2014I was working on a job to send me info each morning about database file free space and was noticing some odd things when looking at the log file VLFs for one of my databases in an AlwaysOn availability group.When I run DBCC LOGINFO on the secondary replica for this database, I get what I expect and most VLFs have a status of 0 (indicating the VLFs are reusable or unused). When I run DBCC LOGINFO on the primary replica, all of the VLFs have a status of 2 (active or recoverable).
Since log backups on the secondary replica in AlwaysOn still truncate the log in the primary replica, I would expect that the VLFs in the primary replica would also be mostly in a reusable or unused state. My log file sizes are the same size on each server and my backups are completing successfully. what might be causing the VLFs on the primary replica to have a status of 2 in DBCC LOGINFO when taking log backups from the secondary replica?
SQL Server Admin 2014 :: AlwaysON Secondary Full Backup?
Nov 12, 2014Recently I have faced one DBA interview, below is the question they asked me.
" Does AlwaysON secondary replica support Full backup, if it is not why"?
I know AlwaysON secondary replicas support only copy_only and tlog backups, why they wont support full backup?
Recovery :: AlwaysOn Listener - Force Connection To Secondary For AD Group

DB Engine :: How To Change Location Of Secondary Data File
Nov 9, 2015I added a secondary data file to TEMPdb yesterday and gave it a wrong location by mistake. If I try to change the location, then I am getting an error now. I think that is because TEMPdb is in use and that is why I cant change it's secondary file's location. Do I need to take TempDB offline and then change the secondary file's location??

2 of the secondary data files had its autogrowth enabled to unrestricted with 200MB and 3 of the data files including primary had its Autogowth turned OFF. Application use is complaining that there is no internal freespace on the DB.
What fails to understand us is that when the Auto growth was already TURNED OFF on 3 data files ( 1 primary and 2 secondary ) still why was the application trying to increase the space on the .mdf and .ndf files; as well when the Autogrowth is TURNED ON on 2 of the secondary data files, why was the DB not able to expand these file groups when the autogrowth is already turned off on 3 of its other files.
What more data i need to ensure i submit an analysis to this.
Increase Data File Size Of Database Which Is Configured For AlwaysOn?
Jun 7, 2015Need to confirm if we can add space(increase data file size) for the database which is configured for always on similar to that of mirroring or we need to follow any different procedure.
I have a requirement wherein the datafiles on both the primary and secondary replica got full, if i add space to the primary database will it automatically get added to the secondary replica or not?
Recovery :: Adding Logins On Secondary Nodes
Nov 13, 2015We have an AAG environment. In order for the failover to be transparent we have to ensure that the login that is added in the Primary node is also added to the secondary node. Currently, we are adding the logins to the secondary node manually. Is there a way to automate this process so that a Login added to the Primary node is automatically updated on the Secondary Node.

Sep 23, 2015If on the source I have a new column, the script generated by SqlPackage.exe recreates the table on the background with moving the data into a temp storage. If the table is big, such approach can cause issues.
Example of the script is below: in the source project I added columns [MyColumn_LINE_1] and [MyColumn_LINE_5].
Is there any way I can make it generating an alter statement instead?
BEGIN TRANSACTION;
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
SET XACT_ABORT ON;
CREATE TABLE [dbo].[tmp_ms_xx_MyTable] (
[MyColumn_TYPE_CODE] CHAR (3) NOT NULL,

The same script is generated regardless the table having data or not, having a clustered or nonclustered PK.

SQL 2012 :: Error At Adding Listener For AlwaysOn
Jun 11, 2015I am trying to setup an AG on a cluster, I was able to define where I want my replica, but I need to setup the ip for the listener of that one
When I am adding the Ip at the listener I am getting the following message:
The Windows Server Failover Clustering (WSFC) resource control API returned error code 5057. The WSFC service may not be running or may not be accessible in its current state, or the specified arguments are invalid. For information about this error code, see "System Error Codes" in the Windows Development documentation.
The attempt to create the network name and IP address for the listener failed. The WSFC service may not be running or may be inaccessible in its current state, or the values provided for the network name and IP address may be incorrect. Check the state of the WSFC cluster and validate the network name and IP address with the network administrator. (Microsoft SQL Server, Error: 41009)
Browsing around I found this guide: [URL] ......
And I make sure that the cluster has permissions to "Read all properties", "Create Computer Objects", even to "Create all child" permissions
I also added those permissions to the account that starts sql at that cluster and I am logged as that and I am still getting the error....

SQL Tools :: Tools To Determine Version From BAK File
Apr 24, 2014Is there - apart from the notorious RESTORE HEADERONLY - an tool which is able to tell which SQL Server version created a specific BAK file? I'm looking for a tool that can be used w/o an available/running SQL Server installation.
Alternatively, is there any documentation about what is read with RESTORE HEADERONLY so I could write a tool myself?
Where would I find the version "bytes" in a BAK file?

created the database file in E: drive. Now E: drive is going to be
exhausted, We are trying to add a new file at different location. When
we add the file into database it creates a file with default extension .ndf
but previous file has the extension .mdf. should we change the extension
of new file to .mdf or we should continue with default extension .ndf.
is it necessary to add a secondary file group or we add a file to the
existing primary group.
thanx in advance

Adding Static Column Of Data From Properties File To DB Import
Sep 4, 2007Hey all-
I put togehter a package that opens a flat file, parses the data based on the semi-colon delimeter, and imports the rows into a database table. Thats the fun easy part.
What I cant figure out is how to add a variable that will hold a constant ID value that will be persisted with the same value to all rows inserted to the DB. Making the problem harder, I would like that this value be defined in a properties file or database table of some sort so that I can do a lookup based on the file name / location to find out what value should be used.
Any suggestions? I hope my explanation makes at least some sense - but basically I want to do a look up in a configuration of some sort, pull out a single value, and add it to a data import.
let the fun begin!!
