SQL Server EE Licensing Question

September 23, 2014, 8:51 am
$
0
0
If I licensed SQL Server EE for production work on one server, SA allows me a free failover replica on another server if not used even R/O during normal operation. MSDN allows me to run SQL Server EE for development and testing. Can I use the developer instance of SQL Server EE as the replica partner for production AlwaysOn AGs if no access was ever made to production data unless a failover had occurred? If I am allowed to do this, and it works, this would save me the associated cost and maintenance with setting up a 3rd VM for the SQL Server partner replica. If not allowed by the license, please provide a reference that covers this scenario. If not desired or possible to do this technically, please explain why. Thanks so much, Dave

Monitor SQL Database mirroring using powershell script

September 24, 2014, 12:19 pm

I am trying use the below powershell script to monitor SQL Database mirroring. The motive here is to determine if there are databases which are in "Disconnected" or "Suspended" mode.

I am running the script on the Principal Server:

$returnStateOK = 0

$returnStateWarning = 1

$returnStateCritical = 2

$returnStateUnknown = 3

$NagiosStatus = ""

 

# Load SMO extension

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | Out-Null;

# Servers to check

$sqlservers = @("$env:computername");

foreach($server in $sqlservers)

{

$srv = New-Object "Microsoft.SqlServer.Management.Smo.Server" $server;

# Get mirrored databases

$databases = $srv.Databases | Where-Object {$_.IsMirroringEnabled -eq $true -and $_.MirroringStatus -eq "Suspended" -or $_.MirroringStatus -eq "Synchronizing" -or $_.MirroringStatus -eq "Disconnected" -or $_.MirroringStatus -eq "None"  -and $_.Name -ne "Master" -and $_.Name -ne "model" -and $_.Name -ne "msdb" -and $_.Name -ne "tempdb"};

 

if ($databases -ne $null)

{

$databases | Select-Object -Property Name, MirroringStatus | Format-Table -AutoSize;

exit $returnStateCritical

} Else {

Write-Host "All Databaes are Mirrored"

exit $returnStateOK

}

 

}

I have Suspended few databases for testing purpose but when I run the above script the output says "All Databaes are Mirrored"

If I make changes to $database and use it below i.e. I am changing the AND operator to OR after "$_.IsMirroringEnabled -eq $true"

$databases = $srv.Databases | Where-Object {$_.IsMirroringEnabled -eq $true -or $_.MirroringStatus -eq "Suspended" -or $_.MirroringStatus -eq "Synchronizing" -or $_.MirroringStatus -eq "Disconnected" -or $_.MirroringStatus -eq "None"  -and $_.Name -ne "Master" -and $_.Name -ne "model" -and $_.Name -ne "msdb" -and $_.Name -ne "tempdb"};

I get the below output:

Name                                                                           MirroringStatus
----                                                                           ---------------

DB2                                                                      Synchronized
DB3                                                                       Synchronized
DB4                                                                   Suspended
DB5                                                                       Suspended
DB6                        Suspended
DB7                                                                      Synchronized
DB8                                                                     Synchronized

I only want the databases which are Suspended or Disconnected to be listed.

Sql Server Transaction Log Backup Fails

I have a Sql Server 2008 Standard version. Mirroring is set up on the server in full safety mode. Its been working fine till today. The transaction log back-up fails every-time with an error

"Error: 2014-09-25 08:34:33.17 Code: 0xC002F210 Source: JuneDB Log Backup Execute SQL Task
Description: Executing the query "BACKUP LOG [JuneDB] TO DISK = N'H:\BKs\Hou..." failed with the following error: "Read on "E:\LDFs\JuneDB.ldf" failed: 1(Incorrect function.)
BACKUP LOG is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly"

I am not able to identify why reading the log file is erroring out. How am I supposed to proceed on this issue.

Things I tried

  1. Ran DBCC CHECKDB([JuneDB]) WITH NO_INFOMSGS returned no error messages
  2. Ran a query to take transaction backup instead of using a Maintenance plan. It gave same error

Update I just noticed at 4:30 AM we ran a maintenance plan to rebuild all indexes. Looking at the error log, I started getting errors for Transaction log backups after 4:30 Am. I am not sure how rebuild indexes could possibly cause the transaction log backups to fail but they sure seem related

SQl server log shipping retention

I have log shipping configured on SQL Server 2008 and the logs retention period is 72 hours . Does SQL Server provide such an option that if the copied logs are not restored on the secondary database (reason the restore job could be failing or any such scenario).

The purge job should not delete those trn files, that are yet to be restored .

To my understanding this is impossible could any one of you please inform me regarding this.

I will be grateful for your help.

How to create a .mdf SQL Server database from a Data-Tier Application file that has data?

October 4, 2014, 6:48 am
$
0

This is a noob question, though I do use SQL Server databases all the time with Entity Framework when I code in C# using Visual Studio 2013.  The development environment is found below at [A].  I am trying to make a clone of a SQL Server 2008 R2 database (.mdf)  that exists online.  I can read, connect and work with this database in Visual Studio 2013, but I wish to make a local copy of the database, as an .MDF file.  Somewhere in my notes I have a way of creating a local copy from an online database when using Visual Studio but I forgot how (it seems, reviewing my notes, that it deals with ADO.NET which is deprecated in Visual Studio 2013 these days, or so it seems).  So I'm looking for another way.  What I did was create (or export) a "Data-Tier Application File" from the online SQL Server database, with data, and it seems to have worked in that this Data-Tier Application file exists on my hard drive and seems to have data in it ("SQL Server Replication Snapshot" is the format it seems).  It contains skeleton code to create a database, but when I tried to execute it with SQL Server 2014 Management Studio, I got a bunch of errors.

So my question is:

1) Can I somehow create a .MDF SQL Server Database from an Data-Tier Application file that has data?  What tool do I use?  I saw this link, http://social.technet.microsoft.com/wiki/contents/articles/2639.how-to-use-data-tier-application-import-and-export-with-a-windows-azure-sql-database.aspx  and it relates to Azure, but is there a tool for C#Visual Studio 2013, standalone?

2) If there's an easy way to create a .mdf SQL Server Database file from an online file, within SQL Server Management Studio?  I don't think so, since it would require Administrator permissions on the online server, which I don't have. I have permission to read, update, delete the online database file, but strangely not to download it (the service I use has a tool for backup, but not for download).

3) same question as 2), but for Visual Studio 2013?  I don't think so, since I notice none of the templates even mentions ADO.NET anymore, but instead they go with Entity Framework.  Using EF I can of course do anything I want with the online database (CRUD), but it remains online.  Maybe there's a switch to make a local copy?  I guess I could write a short program to suck all the data out of the online database and put it into a new, duplicate database having the same tables, that I create on my localhost, but my question here is if there's an easier way than this, maybe a tool or command I can run from inside Visual Studio?

Any advice on any of the above questions is appreciated.

Thank you,

Paul

Different Drive Structure Between Principal and Mirror

September 11, 2014, 7:33 am

We havea 2-node (active/active) cluster with four failover instances installed. We use a dedicated drive for data files, one for log files and one for tempdb per instance .Predicting that we will be adding more instances in the future, we realized that we would run out of drive letters to set up. We intend to switch over and use mounted volumes instead that way we only use 1 drive letter per instance and will be able to add many more failover instances in the future. However, seen as we have over 150 databases across all current instances, reconfiguring the cluster drive setup will require a lot of time and work and is not in the immediate plans for our team (me :( ). I need to mirror as many databases as possible, based on priority, to a DR server on a geographically remote location. Since this server isn't setup with SQLServer yet, I was wondering if it would be a good idea to have the DR server set up with mount volumes now and establish mirroring between our production environment and the DR server that way so that at least half the battle is won. I am aware that the best practice for mirroring is to have the same drive structure between the principal and mirror server, however it is not a requirement. The only example issue I have seen with this set up is when you add a data file to a database and the DDL statements get sent over to the mirror and will fail since the drive setup will not be the same. This is something I am willing to deal with since adding data files to our databases is not something we do often, or at all. As new databases are added and mirrored, the WITH MOVE clause of the RESTORE statement can be used to place the files in their correct location in the mirror server.

Other than this, are there any other things to consider for this kind of mirroring set up?
