SQL Server - Table archive

October 27, 2016, 4:23 pm
$

Hi,

I need to backup a database and restore it on another server.

I have 2 very large tables with 10 years of data and I pretend to, before the backup,  move those 2 tables data to some kind of archive and then do the backup/restore on the resulting smaller DB.

I'm planning to do the following

1 - copy those 2 tables data (every thing with more than 2 years) to a new database just for archive

2 - remove the copied data from its source tables

3 - backup source db

4 - move backup files to destination server and restore to new db

I'm thinking wright?

Is there any better way to do this kind of "archive"?

Any guide/advise?

Thanks you so much,

JD

Slow log backups with high CPU

October 10, 2016, 4:41 am

Hi there,

We are having considerable pain when performing log backups on a large database with many files and partitions.  The database in question is over 1TB and has approximately 4,000 files (for table partitioning).

The command we use is:

BACKUP LOG [MyDb] TO  DISK = N'E:\MyDb.trn' WITH NOFORMAT, NOINIT,  NAME = N'MyDb', SKIP, NOUNLOAD, NO_COMPRESSION,  STATS = 10

The command takes 73 seconds to run (even when there have been very, very few transactions actually recorded), but the output tells a different story:

100 percent processed.
Processed 63 pages for database 'MyDb', file 'MyDb_Log' on file 1.
BACKUP LOG successfully processed 63 pages in 1.610 seconds (0.301 MB/sec).

SQL Server increases about 30% CPU usage during this 73 seconds.

The log file size itself is only about 50mb (since we regularly backup).

What is the log backup process doing to use so much CPU and take so long?

Database Compression - Not compressing my Databases on SQL Server 2014.

Can anyone answer why my SQL Server Database Backups don't appear to be applying the Data Compression option when I submit a backup using the Management Studio GUI (?).  I begin by  setting up all my information in the backup General and Media Options. then in the Backup Options I select the "Set Backup Compression"  to  (Compress Backup).   I then execute this  process...  The Backup completes successfully, however it does not compress the (.BAK) file. 

let me also mention that the sys.configuration  value is set to (1) which is enabled:

Results from Select * sys.configuration table: 

configuration_id name value minimum maximum value_in_use description is_dynamic is_advanced
1579 backup compression default 1 0 1 1 Enable compression of backups by default 1 0

The net result is my backup (.BAK) file isn't any smaller by space than my Data File... 

So it appears SQL Server isn't Compressing my Backup... 

Please Help!

Failed to initialize sqlcmd library with error number -2147024809

I have searched around but cannot find an answer to this so any help is appreciated.  I have a 2014 server with dual instances.  When I execute the following query , it succeeds on one instance but fails on the other with the above error.  This is not related to SQL Agent, this fails on query execution within SSMS as well (on instance 2, succeeds on instance 1).  Names have been changed to generic below.  I have tried with/without various options in the call, nothing seems to work on instance 2, but works fine on instance 1.  IF I remove the @query parameter, I DO receive the email.

EXEC msdb.dbo.sp_send_dbmail

   @profile_name ='Profile1',

    @recipients = 'recipientlist',   

    @subject ='Error in rules-PLEASE INVESTIGATE-',

    @body ='There is an error in rules, a rule calls itself. Please fix.  The broken rule id is:',

    @query='select fields from table WHERE [RuleOnSuccess] = [RuleID] OR [RuleOnFailure] = [RuleID] ',

       @attach_query_result_as_file = 0;

Enable SQL Server Priority Boost to a default 0 or Disable it ?

Based on your experience, is it still dangerous if SQL Server Priority Boost is enabled and set to 0 ( default ) ?

Microsoft is not detailed on the impact of the default setting 0 and setting of 1. I hope to hear some details from your experiences.

Understanding moving primary key clustered index to a new file group.

Hello,

we are planning to move primary key clustered index to a new file group to save some space on primary file group. We are planning to use following command to move it to the new file group,

CREATE UNIQUE CLUSTERED INDEX PK_sales_sales_id ON sales(sales_id)WITH (DROP_EXISTING =  ON )ON [Sales_Index_File_Group]

Questions:
1) As per my understanding the cluster index holds actual data, will the actual data will move to new file group ? how it internally works ? Appreciate if you can provide any other useful internals on this.

Thanks.

All information which I found is devoted to legacy for different versions.

But I need to understand technical different.

Really I asked testing throughput for MSSQL Server on different configurations.

But I have only development editions.

Is it correct to check throughput on MSSQL Server Development edition or I need standard (enterprise)?

Thanks for Help & Regards,

Hello,

We are having performance issues on the SQL server 2012 Ent edition. I was able to trace the expensive queries that are causing the perf issues. But I am trying to identify the host name from which those queries are being executed. Can someone refer me a article which can give host names with the expensive queries consuming high cpu, logical reads etc.

Thanks.

SqlDataReader returns 0 rows when using a SQL login when called from a windows service running under a domain account

November 4, 2016, 3:00 pm
$

Hi,

We have a database problem that I will describe below:

a) We have two database servers and one application server.
b) We have a windows service running on the application server (running under a domain account) which runs a SQL command on both databases. The command uses a SQL data reader. The same stored procedure is called on both database connections using a connection string using a SQL username and password defined in the configuration file. One call returns rows and other one returns no rows.
c) Running the stored procedure on both database servers using SQL management studio returns rows using the same SQL username and password.
d) We created a stand alone application to run on the application server which just made the database call to the database server that returned no rows using the same SQL username and password. Rows where returned. Please note that the standalone application was run using the account logged in which was the domain account.
e) The calls to both databases return rows when running the windows service under the Local System account.

So it looks like running the windows service under the domain account somehow affects the database call even though the SQL connection uses a SQL username and password.

Any ideas?

Thanks
