SSIS syncing databases between like servers

SSIS package to Sync databases between “like” environments, for instance production and test or acceptance.

This package was created in VS2008 and may have functionality only available in 2008 but will work against SQL2005 servers

There is some reliance that the environments will be the same – drive letters, file locations. Users are not synced as part of this package as generally these will be static (hopefully you are using groups) The job uses the admin UNC paths so the package needs to be run with administrative credentials of both servers or shares will need to be created with the appropriate permissions.

  1. The package first queries msdb on the source server and retrieves the paths of the last full backups.
  2. It passes the database name, path and full unc path into a foreach loop container.
  3. The file system task copies the backup to the path defined in the FullDestPath variable
  4. An execute SQL task sets the database (if it exists) to single user
  5. An execute SQL task restores the database using the full admin unc path of step 3 – This could be changed to a share to allow the process to run with less privileges
  6. The loop completes this for all non system or reportserver databases (this is defined in the sql script in step 2)
  7. Success email is sent on completion
  8. There is also an On error event handler at the root of the package that emails any package failure

Package Overview

  1. Parameters

  2. Retrieve Database name and last full backup Path

    1. Create an Execute T-SQL Statement task  against your Source server (msdb database)
  1. With a full result set to an Object data type – here I have used rowset1
  2. Use the SQL statement below,
WITH    BACKUPS
   AS (
 SELECT
    a.Server
    ,a.database_name
    ,B.physical_device_name
  FROM
  (
  SELECT
     CONVERT(NVARCHAR(MAX), SERVERPROPERTY('Servername')) AS Server
     ,msdb.dbo.backupset.database_name
     ,MAX(msdb.dbo.backupset.backup_finish_dateAS last_db_backup_date
   FROM
     msdb.dbo.backupmediafamily
     INNER JOIN msdb.dbo.backupset
     ON msdb.dbo.backupmediafamily.media_set_id msdb.dbo.backupset.media_set_id
   WHERE
     msdb..backupset.type 'D'
    AND msdb.dbo.backupset.database_name NOT IN (
    'Master''msdb''model''reportserver',
    'reportservertempdb' )
   GROUP BY
     msdb.dbo.backupset.database_name
  AS A
    LEFT JOIN (
  SELECT
     CONVERT(CHAR(100), SERVERPROPERTY('Servername')) AS Server
     ,msdb.dbo.backupset.database_name
     ,msdb.dbo.backupset.backup_finish_date
     ,msdb.dbo.backupmediafamily.physical_device_name
   FROM
     msdb.dbo.backupmediafamily
     INNER JOIN msdb.dbo.backupset
     ON msdb.dbo.backupmediafamily.media_set_id msdb.dbo.backupset.media_set_id
   WHERE
     msdb..backupset.type 'D'
  AS B
    ON A.[server] B.[server]
   AND A.[database_name] B.[database_name]
   AND A.[last_db_backup_date] B.[backup_finish_date]
 )
SELECT
   [database_name]
   ,[physical_device_name] AS databasePath
   ,'\\' [Server] '\' REPLACE([physical_device_name]':''$'AS FullSourcePath
 FROM
   [BACKUPS]

   
  1. Set your result set

EXEC('ALTER DATABASE ' @databaseName +  ' SET SINGLE_USER WITH ROLLBACK IMMEDIATE')
  1. Map your parameter like this

    2. DestPath – value ( this is either a share or UNC – it does NOT contain the server name – it uses the DestServer variable so it should be in the format “C$\sql\backups” or “mybackupshare”
    3. DestServer – value
    4. SMTPFailureTo – value
    5. SMTPFrom – value
    6. SMTPServer – value

KB970892 failing and leaving your SQL service stopped?

Finding your SQL service not running is never a recipe for a good day, Recently I’ve seen this happen on numerous occasions when KB970892 tries to apply  to a SQL 2005 SP3 9.0.4035 box -with the System databases moved to a different drive. It appears the patch just looks in the system database data folder for the mssqlsystemresource and distmdl mdf’s & ldf’s. Not in the orginal install folder.

I filed a bug here

As a workaround you can manually copy the mssqlsystemresource and distmdl mdf’s & ldf’s to the data folder your system database mdf’s are in

Knight’s 24-Hour Trainer: Microsoft SQL Server 2008 Integration Services

I buy a lot of technical books, I have at least 10 SQL 2008 books, I normally go for the professional versions and I actually read them. The trouble is there huge! They are a pain to carry round and just plain awkward to read. I usually end up using a stand as most technical books have walkthrough’s or demos – try holding up one of those books or even prop them up while you are trying to type. This means I generally only read in the evenings at home. When I saw the 24 hour trainer book I figured here is a good sized book I can carry around and actually read.

I have always struggled with SSIS, it looks cool and seems friendly but whenever I tried to do anything I couldn’t figure out my arse from my elbow.  I have a need to sync databases, cubes, packages etc between environments. I figured it would be a cool to try and do it in SSIS. Solving my problem and increasing my knowledge at the same time.

I originally started watching the dvd demos and following along. Then I switched to the book – don’t get me wrong it was great to see the packages being constructed – (nice to see it instead of following on from a book). But the book presented the “try it” with hints so you could attempt to build the package without just mimicking the demo. Also the DVD was not the greatest quality – I found it hard to see some of the scripts, when I didn’t have the book in front of me.

I named all my packages as the task that was being covered instead of chapter name as suggested because I feel like I can refer back to them easily- I did all my script tasks in C# – the book was VB only.

Overall I found this to be an excellent book, I really learnt a lot. I definitely appreciate the smaller size.

Note: Authors – how about breaking your books into series to keep the size down.

I’m going to attempt to build my Environment Sync – if it works I’ll post some details

SQL 2008 Reporting services – ReportServerStorageException: An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database.

Had some strange error accessing the history tab and some of the other tabs of some scheduled reports in SQL 2008 SP1.

With a misleading error ”   ReportServerStorageException: An error occurred within the report server database.  This may be due to a connection failure, timeout or low disk condition within the database.”

I at one time restored these databases after a server reinstall from a failed SP1 upgrade. Everything worked for the most part but these odd errors on some reports kept happening.

This error pointed me in the right direction when expanding the schedules tab in SSMS connected with Reporting services
