Recovery :: Log File Size Growing Too Big Need To Truncate In Server With AlwaysOn Feature
May 10, 2015
I want to truncate my sharepoint config database and WSS_Logging database logs the size of sharepoint_config database is growing at a pace of ~10GB every week. I have scheduled a weekly full backup. Current .ldf file size is 113GB.
I am using SQL server 2012 with Always On High Availability feature. I am not able to set the recovery mode from Full to Simple as it gives me message that mirroring is running on both server.
In my case to reduce the log file what I need to do.

We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.

Hello,
I have got another annoying problem. The MDF file size on one of the machines is growing really fast. We zip the mdf/ldf files every day from all the machines in the dataentry dept. On this particular machine, the mdf file size is growing by about 1GB per day. However, when the file is zipped, the zipped file size comes closer to the zipped files from the other machines.
I have tried doing this:
http://www.sql-server-performance.com/lost_data_sql_server.asp
on it as well, but didn't solve my problem.
Any ideas as to what it might be? and how to solve this problem?
Thanks in Advance.
J!

I'm having a problem. When I use the SQL query to make a backup of the database, it worked fine. But everytime I use it, the backed-up file's size kept growing in size. Say I have the file, test.bak whose filesize is 450 MB then I run a new backup to overwrite the existing test.bak file, it just end up as 900 MB. If I run it again, it become 1350 MB and so on.
Is there a way to prevent that from happening?

I was looking to change the file growth setting in our AlwaysOn environment databases.We have a single availability group, one primary and one secondary replica. I learned that when changing the file growth setting on the primary databases (data file), the change flows though to the database on the secondary replica.However after doing the same with the log files, the file growth setting changed on the primary but the change did NOT propagate to the secondary.
Is the solution to apply the change directly to the secondary?here's the T-SQL code I used:
ALTER DATABASE myDB
MODIFY FILE ( NAME = N'myDB_log', FILEGROWTH = 512MB );
GO
SQL Server 2012 (11.0.5532)

Is it alright to move the .bak and .trn backups which are automatically created in a File Share Witness when a DB is added to an Availability Group? I did that and there were error IDs 1069 occurring, and the AG was unable to be brought up whenever I run a load intensive batch job ...

Came across this scenario in AlwaysOn Availability Group (two node), file share witness times out and RHS terminate and cause the cluster node to reboot. File share witness is for continuous failover and if the resource is unavailable my expectation was that it should go offline and should not impact Server or Sql Server. But its rebooting the cluster node to rectify the issue.
Configuration
Windows Server 2012 R2 (VMs)
Sql Server 2012 SP2
Errors
A component on the server did not respond in a timely fashion. This caused the cluster resource 'File Share Witness' (resource type 'File Share Witness', DLL 'clusres2.dll') to exceed its time-out threshold. As part of cluster health detection, recovery actions will be taken. The cluster will try to automatically recover by terminating and restarting the Resource Hosting Subsystem (RHS) process that is running this resource. Verify that the underlying infrastructure (such as storage, networking, or services) that are associated with the resource are functioning correctly.
The cluster Resource Hosting Subsystem (RHS) process was terminated and will be restarted. This is typically associated with cluster health detection and recovery of a resource. Refer to the System event log to determine which resource and resource DLL is causing the issue.

Need 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?

I 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.

We have several Sql Server 2014 AlwaysOn Availability Groups set up in our test lab and use a combination of SCDPM and Maintenance Plans to back up the databases in them.
Our applications always work well regardless of which of the physical servers are, at any given time, designated the "Primary" for a database. Automatic failover works fine.
There are other applications, such as SQL Server built-in backup and System Center DPM that only work properly when the databases are currently hosted where originally intended.
During the normal course of Windows Updates, etc., machines will occasionally be rebooted in the middle of the night. When they come back up, we would like them to "reclaim" the databases that properly belong to them, in an orderly fashion of course (when the "Synchronization State = Sychronized"). We have lots of these test servers and we do not have staff watching the servers in the middle of the night.
Is there an automatic way to accomplish this?

I am setting up a 3 node cluster as part of an availability group.Initially I tested failover between nodes using SQL Management Studio and everything failed over successfully when I stopped a node, and I was still able to write queries. I started to test with an application which connects using an SQL user and whenever I would switch nodes, I would get login failed. I believe the cause of this issue is because the server logins SID's which are tied to the database are different than the server logins on the other nodes which resulted in login failed.how can I ensure that the server logins SID's are the same between nodes? Is there a way of copying this over or how is this supposed to be done? I read a little about contained databases where I could just set the login on the database itself vs. creating a server login but I would rather not go down that route.

hi,
we have a SQL Server 2000 database which we set to 'SIMPLE' recovery mode at 6pm (due to nightly large data loads). We revert back to 'FULL' recovery mode at 6am.
My understanding was that in 'SIMPLE' recovery mode, the transaction log would not grow because it would automatically be truncated after a checkpoint. However this is not the case. I thought perhaps it could be due to a long running uncomitted transaction, but when I ran 'dbcc opentran', the oldest running transactions doesn't last for more than a couple minutes. I manually run a 'checkpoint' command as well in the hope of forcing the transaction log truncation. I repeat this a couple of times to no avail. When I run 'dbcc sqlperf(logspace)' , I can still see the transaction log growing.
It is not until I run 'backup log db with truncate_only' that the transaction log gets truncated.
I do not understand, why the transaction log does not get automatically truncated in SIMPLE recovery mode?

We have a client which they have production 2 node cluster environment. On it around 200 databases with single SQL instance.
Now client wants disatster plan for these 200 database. In these 200 database 3 db's are around 80 GB each databases remaing are less than 5 DB.Note: All these 200 db's are having produciton sites (i mean to say each db is having single site)
For this DR paln clinet is going to provide other DR server,they wants to setup DR between exsting produciton cluster instance to this DR server.
So in this case we have suggest SQL server AlwaysOn availability group.
Here my main question is can we keep all these databases in single AG? .If yes, guidlines to move up. if not, do we have any limitations.Also, best method to setup for this DR plan.

I've set up a SQL server 2014 cluster with AlwaysOn availability groups. Upon creating the AG i opted for full syncronisation to a specific SMB share.Now i want to change that share because it has to move to a new server. How can i do that? I found no settings in the SSMS for that.

I have a db running under simple recovery mode. I am really pressed at disk space, and we have a long running script that keeps failing with "no space left on the device" error. I noticed the log file is very large. I plan to set the max log file size but at the same time I want to know that the database is in the log-truncate mode - perhaps from the database itself. Is there any metadata that could tell me this?

We have an AG scenario where we are using WFC on a 2 node cluster. We are then using AG for mirroring the databases to both nodes and have a listener.
What I want to do next is to establish another copy of the database at a remote location. But I don't want to add the 3rd system to the WFC. I am not a big fan of WFC and I have seen it causes many more problems. The 3rd system will be in a remote location and the network not 100% reliable. I have seen in the past that it causes the entire cluster to hang and causing my production to crash which I don't want.
I there a way to add a 3rd node to the mirror configuration. I don't know if I can add a 3rd node to the AG unless it is part of the same cluster.
I know I can configure log shipping, I am fine with it but in the source, I have no control of which node the DB will be. I am not sure if a log shipping scenario can be configured using the listener instead of the physical host.

We've just started using AlwaysOn High Availability and run into a wierd issue. I have 1 particular database that is not syncing data to the secondary replica. But when i look at all the dashboards, everything is green, they all say synchronised - but if I query the data they are not.
The database has additional sql transactional 1 way replication a different server which i was wondering if was causing any problems, but it's working ok.
I'm just wondering if there's any other more detailed logs i can check to see why the data is not flowing. The availability dashboard and it's event log all says ok.

In the case of a manual failover, what happens to open transactions. Are they killed (rolled back), completed, a little bit of both?
Does the status of the query has any impact (are running queries handled differently then waiting ones, does the type of wait have an impact...)
I am using synchronous commit mode and all I seem to find is reference to the potential or absense of loss of data.

I know that AlwaysOn creates a WSFC role in order to provide failover of the Availability Group Listener. But does it also "honor" the WSFC network setttings? What I'd like to do is isolate the client-side traffic from the database replication traffic. But it's not clear to me that AlwaysOn even uses that part of WSFC.
a) Can you totally isolate the traffic as I've described?
b) Does AlwaysON actually use WSFC network settings? If yes, then I guess I cannot do what I want, since my choices are Cluster & Client, or Cluster Only.

I have had a serious issue with a production AlwaysOn cluster whereby the service did not successfully transition to the secondary node and I cannot find the root cause of the issue.
Some details: It is a 2 node cluster (same datacenter) with a shared disk quorum, Windows Server 2012, both are virtual machines running on VMWare vSphere 5.5. SQL Server version is 2012 Enterprise SP2 CU6
The failover occurred because of a network incident (a spanning tree recalculation caused a connection timeout between both nodes). Initial entries in the SQL Log look normal for this event, for example:
05/08/2015 11:18:06: A connection timeout has occurred on a previously established connection to availability replica 'FIN-IE-PA078' with id [6910F4A9-87E7-4836-BA79-0F41BE90266D]. Either a networking or a firewall issue exists or the availability replica has transitioned to the resolving role.
05/08/2015 11:18:06: AlwaysOn Availability Groups connection with secondary database terminated for primary database 'UserManagement' on the availability replica with Replica ID: {6910f4a9-87e7-4836-ba79-0f41be90266d}. This is an informational message only. No user action is required.
[code]....
My interpretation of this is that the cluster failover attempts failed, because the network condition still persisted. The network interruption lasted approximately 2 minutes, and I would have expected the cluster to come back online at this point, after the restart delay period as suggested in the last entry in the error log. However this did not happen.

We have a SQLServer 2012 Always-On Availability (AAG) Primary and Secondary Node installation/environments. On the Primary node, we have some databases that have the TRUSTWORTHY option enabled (Set to ON). But when the databases are synched/added to the AAG the databases loose the TRUSTWORTHY property and are reset to OFF on the Secondary Node.Because of this,When the instance fails over to the Secondary Node the applications that were working don’t work anymore.
