Hi,
I am working on a project, where we have to migrate from Microsoft Sql Server 2008 to DB2 9 Zos.
Can you please suggest how we can convert the Sql server DDL's to DB2 ZOs DDL's?
I tried with IBM migration tool kit, It converts from Sql server to DB2 9.7 Luw and also there are some issues when this tools does the conversion. Its does not process XML and BLOB data types correctly. |

If an IBM supplied tool does not work properly then contact IBM. They may have a fix, may not have faced this problem before or say 'tough - it says in the manual that this happens' or whatever. But if what you are facing is not documented then they need to know. |

Hi Gylbharat,
As per this link, the migration toolkit does not support it and the tool itself is deprecated.
This link might help you to picture the opposite
SQL Server sql limits are bit higher when compared with DB2 like maximum number of columns DB2 can have, stuff like that. Should review the DDL's in SQL server and compare with the limits in DB2.
What about stored procedures ? Are you trying to migrate that also or rewrite in cobol ?
For XML data, try to check whether they are bigger than 32K if not, as a first step, you can move them to VARCHAR and later to XML datatype.
Thanks,
Sushanth |

Thanks sushanth !!
I already found that document by googling it
There are only tables and views in Sql server database. No other objects.
My only concern is the tables contain LOB and XML data types.
I have not worked with these datatypes before...
I need to work on the performance tuning of these also. These tables will be accessed by dynamic sql through JDBC Driver...
Can any one let me know some best practices (system parameters/table space parameters) in defining these tables on DB2 v9.1? |
