Hi All,

We have plan to Migrate

  • SQL Server DB from 2005 to 2012
  • SSIS ETLs from 2005 to 2012
  • SSRS Reports from 2005 to 2012
  • SSAS Cubes from 2005 to 2012

I would like to know the challenges faced by other people during Migration. I have main concern about SSRS Reports & SSAS Cubes. Is SSRS report developed in 2005 can be opened directly in 2012?

Please suggest if any migration Tools that can help us in doing the same.

Thanks Shiven:) If Answer is Helpful, Please Vote

Query grows tempdb after moving from SQL 2008 SP1 to SQL 2012 Core SP1

March 22, 2013, 7:05 am
$

I have a query that has been running on a SQL 2008 server for time. It takes about 4 hours to run. The largest table referenced in the query is an 8GB fact table.

The database was restored to a SQL 2012 Core Server. The query would then run for 8+ hours and fail with a message that more space was needed in tempdb.

Space was added to tempdb, but the query still failed. Usingsys.dm_db_task_space_usage, was able to see the space used in tempdb per connection.  More than 800GB (sic) of space was consumed in tempdb.

I looked at the data in each of the tables used in the joins. I was expecting to find a Cartesian product returned from one of the joins. This was not the case.  The join column from every table  was unique in one of the joined tables.

I overcame the issue by adding each join to the statement individually and then seeing where the issue arose. If I only joined three of the tables the query would return TOP 1000 immediately.  When added together, the final join caused an issue. The TOP 1000 would not return after 20 minutes.

I changed the query to load data to #temp tables and then joined the #temp tables to the rest of the tables. Each join to the #temp tables performed quickly and did not create an explosion of growth in tempdb.

The question still remains, however,why did the query complete on a less powerful 2008 server, but fail on a more powerful SQL 2012 Core Server with more memory and space?

Pseudo code…

--Before query

select *
from table1 t1
   inner join table2 t2 on t1.id = t2.t1_id
   inner join table3 t3 on t2.id = t3.t1_id
   inner join table4 t4 on t2.id = t4.t1_id
   inner join (
      select col1, col2, max(col3)
      from table5 t5
      where date > @date
         and col1 = @col1
      group by col1, col2
      ) as dt -- derived table
         on dt.col1 = t1.col1
   inner join table6 t6 on t1.id = t6.t1_id

--After query
select col1, col2, max(col3)
into #temp1
from table5 t5
where date > @date
   and col1 = @col1
group by col1, col2

select *
into #temp2
from table1 t1
   inner join table2 t2 on t1.id = t2.t1_id
   inner join table3 t3 on t2.id = t3.t1_id
   inner join table4 t4 on t2.id = t4.t1_id
   inner join (
      select *
      from #temp1

         on dt.col1 = t1.col1

Broker Service options when migrating databases from an Enterprise server to a Standard server.

March 26, 2013, 12:49 am

Hello.

A Customer wishes to migrate his databases from an 2008 Enterprise installation to a Standard installation.

Some databases have activated Broker Service and some have not.

When migrating the first database that has Broker Service activated, Broker Service is not activated and it activates using ALTER DATABASE ENABLE_BROKER. However the next database cannot have its Broker Service and an error states something about the Broker Server ID must be unique (or something like that).

Now, the customer would like to know which option he has regards Broker Service and what consequences those options results in.

1) ENABLE_BROKER: How can this be done for more than the first database?

2) DISABLE_BROKER: If database had Broker Service Enables on the Enterprise server and will not have it on the Standard, what will not work?

3) NEW_BROKER: Personally I suspect this is the way to go, but will it work? This would give the database a new Broker Server ID and what consequences would that have?

4) ERROR_ BROKER_CONVERSATIONS: What is this?

5) HONOR_BROKER_PRIORITY (ON/OFF): What is this too?

The main goal regarding Broker Service in this migration is that Broker Server should be activated on the same database on the Standard server has they are on the Enterprise server.

TIA

Best Regards

Bug found - SQL 2012

I just want to report a bug I found.  I've recently updated a database from SQL 2008 to SQL 2012.  This morning a daily procedure failed.  Upon further investigation I found a view had been updated as follows: 

SELECT     PolicyKey, Policy, PolicyStartDate, Sequence, Amendment, Status, RatingStatus, OldPolicy, ClientNumber, TransactionType, EffectiveDate, BillingType, NextBillingType, Reversed, BusinessLine, BranchCode, GroupCode, BrokerCode, PolicyEndDate, PreviousInsurerCode, PreviousPolicy, RequestLetter, RenewalCode, RenewalBusinessLine, NonRenewalRemark, AmendmentCode, AmendmentRemark, InsuredSince, InceptionDate, DatePrinted, PostDate, DatePosted, ShortRate, Subscription, LeadPolicyNumber, PrintPolicy, BusinessType, BrokersCancelDate, UploadedFromBroker, BrokerIDForInsured, IneligibleforPHIX AS HeldBy, HeldBy AS DateHeld, DateHeld AS HeldByUniID, HeldByUniID AS AddedBy, AddedBy AS DateAdded, DateAdded AS ChangedBy, ChangedBy AS DateChanged, DateChanged

FROM         GIMS.dbo.Policies


Please note the section where a field had been added to the table (IneligibleforPHIX) and SQL tried to compensate by adding the AS keyword to retain position.  This ultimately offset the entire result set by 1.  IE: 1 as 2, 2 as 3, 3 as 4, 4 as 5...  etc. and completely screwed up the data selection from it.

How to map MySQL bit(1) column to SQL Server bit column using SSMA

So I'm trying to migrate a MySQL database to SQL 2012 Express using the SQL Server Migration Assistant for MySQL and am having issues getting the bit(1) fields in my MySQL database to map to bit fields in the target SQL Express database. They're getting mapped to binary(1) and I have no way of adjusting the type mapping.  Is this even possible without having to manually alter the SQL Server tables after the migration?

Alternately, is there any way to preserve the boolean datatypes of my EF Code First classes that are mapped to the bit(1) columns in my MySQL DB's tables when EF is expecting them to be byte[]?

Thanks, -MrB

Hi,

I had converted schema and was trying to migrate data Sybase 11 to target SQL Server 2005 locally through SSMA 5.2. But I have one issue with data. With unique clustered index, it doesn't allow me to migrate data. So first step:I deleted the index manually in targat SQL server. Then try to migrate data but there was first row in two columns(sector,category) are repeating for all other rows for those two columns. See below is source data(total 234  records) and migrated data.

I think this is issue of SSMA 5.2 for migrating data. Is there any workaround for this issue. I have to finish task for my client by EOD tomorrow.

Any help much would be much appreciated!!!

Thanks,

Preciso resolver isso hoje ainda. Se alguém puder me ajudar, agradeço desde já.

Hello,

I have upgraded from VS2008 Professional to VS2010 Professional. I have VB 2008 applications that use SQL Server 2005 Express and were working on my development machine (XP) and on the machines on which they were installed using VB2008 Setup Projects. I have installed VS2010  on my development machine and insatlled all available updates. Then, I copied one of my existing applications from the VB2008 Projects folder to the VB 2010 Projects folder and opened it in VB 2010, where it ran the upgrade to VB 2010. After it finished upgrading the appliacation to VB 2010, I tried to run it in debug but I get the following error at the piont where the SQL db is supposed to load and fill inforamation on a form in my application:

Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance.

I finally got SQL Management Studio installed and did queried the istalled SQL versions. I default version is SQL Server 2005 Developer Edition SP3. The SQLEXPRESS version isMicrosoft SQL Server 2008 (SP3) - 10.0.5500.0 (Intel X86) Sep 22 2011 00:28:06 Express Edition on Windows NT 5.1 <X86> (Build 2600: Service Pack 3). I have also run the sp_configure 'user instances enabled',1. Reconfigure query and that did not fix the problem.

I am stuck with this error and have read many suggestions that do not fix the problem. Below is the error detail. Can you tell me how to fix this problem?

Thank you,

Dan

I've installed SSMA for Oracle on the server where the Oracle instance resides.

When I "Connect to Oracle", I fill in all the necessary connection details.  It gives me some warning about some permissions I'm missing:

but otherwise seems to proceed OK.  Then it starts "loading objects"... and progresses slowly from 0% to 54%... and then it locks up at 54%.  I left it running overnight, and this morning it's still stuck at 54%.  The process in Task Manager is showing zero activity.

What is wrong?  How do I fix this?
