SSIS Custom Source Component for EBCDIC

Well, it’s finally done!  Patrick and I finished version 1 of the EBCDIC Source Component which aids tremendously in the importing of EBCDIC (mainframe, IBM, old school stuff) data into SQL Server Integration Services.  We think this component will allow a number of shops to focus on getting the data right in their ETL solution within Integration Services rather than beating their head against an older data format that doesn’t always play well with others.

This component, named Lysine, works like most other Sources in SSIS so it should be easy to get started.  Currently, the component has the following features:

  • Several EBCDIC code pages supported
  • Intuitive Layout UI for rapid  development
  • Quick Preview to show you if your layout is correct
  • All major column types supported Redefines, Occurs, Occurs Depending, Packed (Comp-3), Zoned
  • Single Pass conversion for scalable performance
  • Export/Import of layout for team development

Please come check out the demo, browse the User Guide, try some Samples and let us know what you think!

SSIS Custom Component – ProvideComponentProperties vs ReInitializeMetadata

Filed under: .NET, Custom Source Component, database, Integration Servicees, SQL Server 2005, SSIS, Technology — benjamin harrell @ 9:47 am


I am currently working on a custom source component in SSIS that converts EBCDIC data to ASCII inline and one of the challenges I face is creating dynamic outputs and output columns based on the layout process of the source component.  Normally, when you want to additional outputs on your component you create them in by override ProvideComponentProperties like this:

public override void ProvideComponentProperties()
    // add the outputComponentMetaData.UsesDispositions = true;
   IDTSOutput90 output =     ComponentMetaData.OutputCollection.New();
   output.Name = “My New Output”;
   output.ExternalMetadataColumnCollection.IsUsed = true;

This works really well if all of your output information is available at design time (in the SSIS ui) but what happens if your dynamic outputs are determined at runtime?  ProvideComponentProperties is only called one time, when the component is added to designer surface.  In order to dynamically add outputs at a later point you must use ReInitializeMetaData which is called whenever Validate returns VS_NEEDSNEWMETADATA.

public override void ReinitializeMetaData()
   // add the output
   ComponentMetaData.UsesDispositions = true;
   IDTSOutput90 output = ComponentMetaData.OutputCollection.New();
   output.Name = “My New Output”;
   output.ExternalMetadataColumnCollection.IsUsed = true;

Note that I have not shown the additional work of adding columns to either of these scenarios, you will need to add that code yourself.

SSIS Row Limits and DefaultBufferMaxRows

Filed under: C#, database, errors, Integration Servicees, SQL Server 2005, SSIS, Technology — benjamin harrell @ 9:51 pm

I had an odd issue during some testing I was doing on a custom source component I’m writing for EBCDIC data conversion.  I first assumed that surely my code was at fault but the test just seemed to simple to be “my code”.  So here’s the scenario,  I have a file with 100,000 bytes of the number ‘1’ in EBCDIC.  I created a simple package to import the file as 1 byte rows into a Dataset Destination.  I was surprised when I executed the package and found that only 65,536 rows were processed.  Now if you have been around software for more than a week you probably recognize this magic number and unfortunately it triggers all sorts of theories about what could possibly be going wrong.  Well, I’m still trying to investigate the “why” and I’ll update this post and welcome comments if anyone has input but for now the solution to this oddity is to increase the DefaultBufferMaxRows to greater than your number of records.  This seems like a horrible workaround for a situation that should happen quite often so the hunt continues…

 Thanks to Fritz Laurel for adding this in the comments section, after you gain access you may need to run this script to store the new default database for the Login you used.

Reporting Services 2005 Rotation and Orientation

Filed under: .NET, ASP.NET, C#, Reporting Services 2005, SQL Server 2005, Technology — benjamin harrell @ 4:54 pm

As many of you might have figured out by now Reporting Services 2005 doesn’t support rotating objects or multiple orientation (as in per sub report).  Depending on your situation there might still be an answer.  I was in a situation recently where I need certain pages of a report in landscape and some in portrait.  I was told that this is not possible out of the box in Reporting Services 2005 but have since found a workaround that might work for you.  Microsoft has done a great job with making SSRS an open architecture and the web services are a key part of this approach.  Behind the scenes of your Report Viewer control (in “remote” mode) it is actually making a request to the Render command of the SSRS Web Service.  So to pull of the rotation of a report I created a new web page with a web reference to the ReportService.  I then request the report in IMAGE format and store the byte[].  I create a new Bitmap object and stream in the byte[] so that I have full control over my newly created report Image in GDI.NET.  Bitmap supports a RotateFlip method that has just what we need and then I save the Bitmap to the Response.OutputStream object.  You are probably familiar with the concept of pointing an Image to an ASPX page that dynamically generates the bytes of the Image and this solution is no different.  Once you have an ASPX that can generate a rotated Image of the report then you treat it just like any other Image in the Report or on a WebForm.

Cannot open user default database. Login failed. Login failed for user ‘UserName’. (Microsoft SQL Server, Error: 4064)

Cannot open user default database. Login failed. Login failed for user ‘UserName’. (Microsoft SQL Server, Error: 4064)

This error bugged the crap out of me tonight and I saw all kinds of crazy answers usually involving some sort of SQLCMD -blah -blah…i think this maybe the problem with command line happy developers/dbas but to make a long story short the fix is EASY and you will kick yourself for not trying this.

1.  click the options button if the options are not showing.

2.  click the connection properties tab if it is not active

3.  click on the Connect to database: dropdown

4.  type in the name of a database that still exists (ex. ‘master’)

5. connect!

I heard all kinds of rants and raves about how atrocious it was that microsoft did this to us and I agree it does suck that SQL Server doesn’t do something about this automagically but what would you suggest it do?



[UPDATE]  I wanted to move some of the great ideas in the comments to the top so that people could find other solutions more quickly:

From Commenter Fritz Laurel:


From commenter Das:

For those of you who use their Domain accounts, here is the Alter statement to run once you assign the MASTER DB from the above step.


Replace [BUILTIN\Administrators] with your [domain\usr]

NOTE:[Brackets] required on Domain\User accounts

From commenter Breb02 (SQL 2000?)

sqlcmd -E -d master (osql -E -d master for SQL 2000)
1>sp_defaultdb ‘Computer\username’, ‘master’

Later SQL Server versions:
sqlcmd -E -d master

From commenter Fuad Ahmed

And the solution for me was just switching the registration property of the server from sql authentication to windows authentication.

I think I was lucky that the login sa had different default database and the windows authentication had different.

From commenter Tony G

I’m using VS2008 Server Explorer. I opened Modify Connection, Advanced Properties, and just set User Instance to true. That allowed my local SQL Server to open the local mdf. HTH

From commenter BobG

I had to.. Under my “registered servers” list, pick the offending server/instance and then right click, choosing “properties”, then choosing “connection properties”, and then type in a database name in the offending server/instance in the “Connect to database:” drop down box.

Then I was able to get in but no offered choices from this post worked for me beyond getting back in, and I had very little rights/access.
I wound up deleting my login from the Server/instance under “Security”. Then I was able to close MS SQL Studio and went back in without further issue.
Note: I also have that same account, a domain account, that I had deleted listed under other SQL Domain Groups for the offending server/instance.

From commenter PeterG

I am running Win7x64 and once of a sudden could not open my DB anymore. I ended up having to “take ownership” of the folder with the DB inside and viola – it worked

From commenter Adrian

To repair an an SQL Server 2000 with default db detached I made the following :

1. I used SQL Server 2005 management console from a client PC and get connected to the server to another existing database;

2. Created another user :
EXEC sp_addlogin ‘Adrian’, ‘p1234′

3. Re-attached the default database with :
EXEC sp_attach_db @dbname = ‘ATOTAL’,
@filename1 = ‘C:\ATOTAL DB\atotal_Data.MDF’,
@filename2 = ‘C:\ATOTAL DB\atotal_LOG.LDF’

From commenter spiritos

I couldn’t connect either (default db not found) so tried this fix but I couldn’t even browse the server to select a new db to use. As a result I started looking at the Security for the db… turns out there was a db that was restored (just happened to be my normal login’s default db!) but in the process some Users had been dropped from the Security folder – including the group that my “normal” login belonged to! Added these groups back in then could connect again!

From commenter One IT Services

You don’t have to use any commands at all, if you still have a login that works then use that to first login to the object explorer.
If you don’t then when logging in make sure you do as stated in the blog which was to click the options button on the Connect to Server Screen.
Then on Connect to Database just click Browse Server, say yes to connect and select any database from the list.
Then once you’re in the Object Explorer, expand Security, Logins and select the username you need to fix.
At the bottom of the Login Properties box you just need to select a Default Database, most likely Master.

From commenter vishalsharma

Note : you have to type master in default database drop down. You won’t see it there in the list.


I hope some of these most appreciated comments will help others!
