How to do a live migration a large SQL database to another data center across the Internet

July 31, 2013, 10:00 am

I have a 350GB SQL database in 2008 R2 that needs to be migrated to another data center. I have already P2Ved the server and setup the VM in the new data center. All that's left is to sync the changes in the two SQL servers across the Internet and then update our DNS for the application to point to the new data center.

What is the best way to sync the two SQL databases being the destination server is a snapshot image of the source server (down to the bit level) as of a couple weeks ago? Is there a 3rd party tool under $1000 that can do this?

Thank you,

Migrating 2005 SQL Server to 2012 SQL Server with Database Compatibility as 2008R2

I need to verify my reasoning.  I want to make sure my logic is correct.

I am migrating two 2005 SQL Server databases.  However, the application requires that the upgrade be to SQL Server 2008 R2 and not to SQL Server 2012.  My instance is 2012.  If I do a restore and set the compatiblity to 2008R2, will the database operate as a 2008R2 database even though the server is 2012?  I shouldn't then have an issue with the application, correct?

Problems Restoring SQL Server Database

Hello everyone and thanks for your help in advance.  I did a recent install of SQL Server 2005 on a test machine (Windows 7 Ultimate).  I took the backup from our production database (SQL Server2000) (Everyone, please hold the groans and dinosaur comments!).  Took full DB backup file *.bak of current production system. Selected  "Overwrite  the existing Database"  and "Leave the database  ready  to use by rolling back uncommitted transactions.  When I run the backup, I receive the following error:  System.Data.SqlClient.SqlError: RESTORE detected an error on page (0:0) in database "myDB" as read from the backup set. (Microsoft.SqlServer.Smo).  Obviously, the first thought is the backup file is corrupted.  I reran the backup and received the same problem.  Finally, I tried restoring this backup file to another machine running SQL Server2000.  The restore executed correctly and restored the database.  I really have no idea where to go from here.  Any help would be appreciated.

SQL Server in WOW mode?

We're looking in to upgrading our SQL 2008 SP3 cluster to SQL 2012 and I see something about not being able to upgrade a SQL cluster running in WOW mode.  I read up a little on WOW64 and understand what it means to run 32 bit applications on a 64 bit OS.

But how do i tell if my SQL cluster is running in WOW mode?  I inherited this cluster and didn't originally build it.

Thanks,

Upgrade form Sql2008 Standard to sql 2008 Enterprise

ello,
We have currently build new Server 2008R2 with 8 core CPU with 32 GB Memory and currently working to get license for sql server 2008R2 Enterprise edition.
We have currently sql 2005 standard and planning to migrate to new server as mentioned above.

1) If I upgrade 1st using sql standard edition and later upgrade to Enterprise with using 8 core CPU with 32 GB Memory will be ok?

Can we upgrade form Sql2008 Standard to Enterprise Edition?
Let say we have sql 2008/sql 2008R2 already running and I would like to upgrade to sql 2008/sql 2008R2 Enterprise Edition.
Is it just upgrade instance wizard I have to follow?
Reading from the articles, little confused that is it we need to do another backup/restore too?
If I install just cd and run the upgrade Instance wizard will be work or any other procedure I have to follow?
I think I just need to restart the service and server, correct?

2) I have another question is that if I download from the technet for testing then if I have to upgrade it using production licensed key, can we do and is it the same way?

option 1) I mean if I start to use TechNet for testing
and then later upgrading license key to a production will work,
right?

option 2) And I start to begin migration using sql 2008 standard
and at a later date upgrade to Enterprise (it will be 8 core pocessors and 32 GB
MEM) will work also?

Thanks,

SSMA 2008 not showing new Oracle schemas

August 6, 2013, 9:06 am

Hello,

I have a SSMA project from several months ago and need to re-run it to load the newest data from my Oracle database into my SQL Server 2008 R2 database.  Since the last data migration run, three new schemas have been added to the Oracle database.  I open the project and connect to Oracle but when I look down the list of schemas from Oracle, I am missing the new schemas.  "Advanced Object Selection" does not show the new schemas either.

I tried to right-click on "Schemas" immediately under the name of the Oracle database and select "Refresh from database".  SSMA runs for several minutes and then reports "Nothing to process by this operation because all objects are equal".

I am connecting as the Oracle SYSTEM account and have confirmed that this account can see all schemas and all database objects.

I also tried to change the default project setting GUI -> Misc -> "Maximum row number for source" and "Maximum row number for target" to 500 from 100 (even though I have less than 100 Oracle schemas) but this didn't make any difference either. 

This is extremely frustrating as I have a deadline this week for the data migration.  Does anyone have any idea why SSMA isn't showing all the Oracle schemas?

Any help gratefully appreciated.

ntext and nvarchar(max)

I migrated a database from SQL 2000 to SQL 2008.

I understand that SQL 2008 will not support nText field type, but it seems that it still working using nText.

I have nText works in SQL 2000 for years and keep it in new SQL 2008 database.

I use UPDATETEXT to update the table.

I just realized that it happens a few times that sometimes UPDATETEXT updates and override previous user update.

For example, one user update one record at 08:00, and seond user update another record at 10:00.

The seocnd users update 2 records for the current record and previous user record as well.

I just want to know any user report this issue and if there is, any work around for this?

Should I just change the field type to nvarchar(max) and use normal update report to fix this?

Your help and information is great appreciated,

Regards,

Souris,

SQL Views-sorting issue in SQL 2008

Hi Guys,

We are migrating from SQL 2000 to 2008R2

While testing,we have encountered a problem with SQL views sorting. SQL views are behaving differently in SQL 2008. i read in blogs that 'Order by' doesn't support in SQL 2005 and higher versions.

Work done to resolve this issue:

We have tested views with Top 99.99 % and it works fine for us.(confused about logic behind this)

- Large number of views are being used in Application, so we can't change thousand of views with Top 99.99%.

I'm not interested in change large number of views. So please let me know, if there is hotfix for this problem.

Hello,

I'm trying to migrate a database Mysql 5.1 to SQL Server 2008 with SSMA.
The server hosting the SQL database is on Windows 2008 Enterprise x64.
The user connecting to the SQL database is sysadmin.
Phases to convert and sync happen without problems, but the migration of data blocks it.
The log tells me out:

Data migration operation has finished.
0 table (s) successfully migrated.
0 table (s) Partially migrated.
46 table (s) failed to migrate.

The Data Migration Report is empty with only a red cross next to my table names.

I tried to migrate in client mode and server mode = same result.Any ideas ?

 

EDIT: miss, this thread shoud be in section SQL Server Migration. A moderator can move my post please ?

Hi All,

I keep on getting this error:

Msg 241, Level 16, State 1, Line 1
Conversion failed when converting date and/or time from character string.

I'm using the Try_Parse code for datetime here is the exact codes.

SELECT * FROM Table1
WHERE ISCLOSED = 'FALSE' OR (ISCLOSED = 'TRUE' and (CREATEDDATE >= TRY_PARSE('01/01/2010 12:00:00 AM' AS DATETIME USING 'en-us')))

What's bothering me is I used this code with my other tables but worked fine and perfectly. all tables I have were all uploaded the same way.

I am using SSMA for sybase to migrate data from Sybase to SQLServer 2012.

The source database(Sybase) has more than 100 tables. I am able to migrate all other tables except 2 big ones.

It is showing error message

[DataDirect ADO Sybase Provider] Can't allocate space for object 'temp worktable' in database 'tempdb' because 'system' segment is full/has no free extents. If you ran out of space in syslogs, dump the transaction log. Otherwise, use ALTER DATABASE to increase the size of the segment.

The two tables raising this error has around 20 and 47 millions of rows each.

Please help me in resolving this.

I have a number of access databases I would like to convert to SQL and host on Windows Azure with an ASP.net website.  I have considered outsourcing the project or hiring staff, but finding people with the right skills/experience is very difficult. Is there a trustworthy source to look for companies and individuals that provide this type of service?

Hello All

We are currently going through an upgrade to our server hardware and software.

We have SQL 2008 r2 Work group installed on our current set up and want to move it too our new set up from windows server 2003 to server 2012

We have the certificate of authenticity and the product key we don't have have a installation disk.

We outsource our IT support and they have stated that we cannot migrate onto new hardware

It isnt an OEM product though and was purchased separately 

I have read a few articles and i have had mixed answers.

I just wondered if it was possible and how it can be achieved 

Many thanks

Michael Beattie
