We have 2 nodes SQL 2008 Server 2008 R2 cluster installed on Windows Server 2008 R2 W/SP1 Operating System.

I have the following issue:

I need to bring cluster resource manually onling frequntly plus I found the following error in cluster event:

Event: 1587

Cluster file server resource 'Resource Name' failed a health check. This was because some of its shared folders were inaccessible. Verify that the folders are accessible from clients. Additionally, confirm the state of the Server service on this cluster node using Server Manager and look for other events related to the Server service on this cluster node.

Event: 1205

The Cluster service failed to bring clustered service or application 'SQL Server (MSSQLSERVER)' completely online or offline. One or more resources may be in a failed state. This may impact the availability of the clustered service or application.

Event: 1069

Cluster resource 'Resource Name' in clustered service or application 'SQL Server (MSSQLSERVER)' failed.

Does SQL Backup to a Temporary Folder?

October 28, 2011, 11:32 am

When running an SQL backup, does SQL first write to a temporary folder prior to actually saving the bak to the target directory?

If this is true is there a way to re-direct this temporary folder to a different location?

The issue is that on a very large database there may not be enough hard drive space where the temporary folder exists.

Thanks.

If I start a full backup from a client (SSMS) in China, but both server and backup location are in the US, does all network traffic stay within the US, or does it have to transverse over to the client machine and back?

If I start a full backup from a client (SSMS) in China, but both server and backup location are in the US, does all network traffic stay within the US, or does it have to transverse over to the client machine and back? I imagine the answer is obviously the traffic is only between the server and the backup location. But not always things are programmed in obvious ways. So, anyone?

TIA,

I have the 2 node Server 2008 Cluster set up as active / passive, I also have the 2 named instances of SQL set up with it own disks.  My issue is that is the named Instance 1 fails and goes to Physical Cluster Node 2 and Instance 2 stays on Physical cluster Node 1 then it becomes Active / Active and requires additional SQL licensing costs.  What can I do to ensure that both Named Instances stay on the same physical node so it stays Active / Passive?

Best SQL backup strategy

July 24, 2013, 1:51 pm

I've been working with a customer on a project that started small, and has grown significantly.   It is a retail environment, and we are taking live transaction data from the POS system, and loading into SQL server for reporting and online presentation.  My experience has been mostly with smaller SQL dbs, nothing involving multiple servers.

The SQL database file is started at less than 6GB, and is now ~25GB  6 months later, and will only grow.  They currently have a single SQL 2012 Server, with nightly full backups to a NAS.

They bought a second physical server to be a standby / DR back up in a second physical location.  The IT Manager quit before they set this server up, and they have asked me to step in to complete the project.

What would be the best strategy to ensure DR and high availability given this set up?

My initial plan is to install the second SQL into a VM on the new hardware then set up replication from the first SQL. Would this be good enough to eliminate the nightly full back up?  Can I then just do backups on the VM? What about clustering?

Thank you for any suggestions.

Hi..

I am Using visual studio ultimate 2010 and SQL Server 2012 enterprise edition...

I have a database name as 'GBTest'

I just implemented ALWAYSON High Availability using 3 nodes in SQL Server 2012 latest feature...

among 3 nodes one as primary node and other two as secondary nodes. and 'Readable Secondary' option is 'No' on primary node and 'Yes' on two secondary node.

CLUSTER Name :- GBCLUSTER01

Availability Group Name:- GBTest_AvailGroup

and I am changing web config like this...

<add name="ConnectionString"
connectionString="Data Source=tcp:GBTest_AvailGroup,1433;Initial Catalog=GBTest;Integrated Security=SSPI" providerName="System.Data.SqlClient"/>

But its return a error...

I think there is some problem in my connection string ...Can anyone tell me the actual connection string??

I am successfully configured ALWAYSON High availability feature.

First time when I manually stopped the service of primary SQL Server then automatic fail over is working properly and Secondary server now becomes a Primary server.

But when I manually stopping the service of new primary server then availability group is inresolving mode and database is in not synchronizing mode andautomatic fail over is not working. and then after restarting the SQL Server service all are working well??

But when I clicking on 'failover' button from availability group name and follow the next step then its works properly.

So can anyone tell me why automatic fail over is not working afterfirst time and why availability group is in resolving mode and database is in notsynchronizing mode??

Cluster MSDTC in a SQL Server 2008 / Windows 2008 Cluster?

May 6, 2011, 7:06 am

Hi - we are configuring a new SQL Server cluster.  The cluster details are the following:  2 nodes, Active/Passive, SQL Server Version = 10.0.4000 (SQL Server 2008 SP2) and Windows 2008 Service Pack 2.  This cluster will be in production, and my question is the following:

Do we need to cluster the MSDTC resource? 

We have an ongoing debate about whether to cluster MSDTC on this SQL Server cluster or not.  We're just beginning to swap out our Windows 2003 / SQL Server 2005 clusters with new Windows 2008 / SQL Server 2008 clusters, and some of our DBA's have said with Windows 2008 the need to cluster MSDTC is not necessary for high availability as it was in Windows 2003.  We can use the local DTC on each node.

My concern is during an unexpected failover of the SQL Server services how will transactions be handled if we do not cluster MSDTC?  Couldn't we lose transactions?  This would not be good (financial impact) if we lost transactions. 

Some of our DBA's are very adamant that this isn't necessary (clustering MSDTC on the new Windows 2008 clusters).  But when I research Microsoft seems to recommend clustering MSDTC for high availability.  But why offer that option if Windows 2008 has redesigned MSDTC so you don't have to? 

Need some advice\perspective.

Perf issue with media set size for transaction log backups

July 25, 2013, 9:38 am
$

We have a highly transactional database that's mirrored (and thus in recovery mode = 'FULL') so we have to perform regular transaction log backups between full database backups.

The transaction log backup grows very fast. We have plenty of space, but the issue is that as the day goes on (until the next full backup), the media set (I think that's the correct terminology) on disk grows and grows. And for each subsequent transaction log backup, we see start pegging read i/o on that disk.

The behavior seems to be that we seek to the end to append the latest transaction log backup by reading the entire file.

Are there ways to mitigate this behavior? My colleague says to rotate the media set (i.e., transaction log backup file) more frequently to reduce the max size. I also explored having the media set consist of multiple media families (e.g., three different files on disk). But my colleague postulates that this would not solve the problem because ultimately the same amount of seeking will have to be done (albeit on three smaller files). Perhaps if these files were on separate disks we might see a win.

Anyway, am I correct in my analysis with regards to large media set on disk requiring lots of read i/o to successfully backup subsequent transaction logs?

Hi,
We have a Active/Passive cluster set up with 7 instances of  SQL 2005 SP4 Enterprise(64 bit).
Daily at 2 AM the SQL Cluster group is restarting on same node or failing over to the otehr node with errors starting with:

SQL Server has encountered 1 occurrence(s) of I/O requests taking longer than 15 seconds to complete on file  in database.  The OS file handle is 0x0000000000000B98.  The offset of the latest long I/O is: 0x000012b0dfe000

/*there are many occurences of the above message on many instances and particularly msdb database*/

Event Id 4156 MSDTC - String message: ProcId = 0x2188 CSO: Maintain session; Received E_CM_SERVER_NOT_READY.

Above errors are logged in the system logs and all the sql cluster groups are either restarting or failing over to other node every day from past one week  around 2AM.

Backup jobs are scheduled to run at 2 AM on 4 instances same time every day.Could you please tell me if this is related to the backup jobs.We have different drives(for every instance and also different data/log/tempdb drives).
If this is not due to these backup jobs,could you please tell me how i can troubleshoot on this.I am suspecting a memory/io bottleneck but why is it failing now only which is running from from past few years.Please tell me which performance counters i can collect to resolve this issue.

Hi,

I am configuring SQL AlwaysOn backups in our environment. The first step will backup the databases, that works fine, the last step is to remove files older than 3 days, that works fine ...The problem is the Shrink Database command that runs second wont work ..it keeps failing with the error:

"Property Size is not available for Database 'Database_Name'. This property may not exist for this object, or may not be retrievable due to insufficient access rights. "

I've googled but cant find anything related to this error. I can run sp_helpdb and get all of the information i need (when connecting in with the ApplicationIntent=ReadOnly switch)

I am running the backups from the secondary server. Is it not possible to Shrink the DB from the secondary server as this runs fine from the primary?

cheers,

Jon
