Walks you through the process of using the Extract Schema UI tool to download the standard DSN schema from your DB2 database
in the form of an XML file that contains its information, and view that file in a text editor.
Extract the DSN schema
Note: To extract CREATE VIEW statements with proper translation when using DB2 for z/OS version 10 and higher, you might need to
set the
Cast STATEMENT column to VARCHAR during SysViews extract Extract Schema option to
True. See the
To set HCOSS Options and
Options topics for more information.
- From the HCO for SQL Server interface, click
Extract Schema. This takes you to the
Schema Extract tab.
- Click
New.
- In the
Schema Extract Name field, type
schema-name where
schema-name is the DSN schema name for your version of DB2, which varies depending on the version:
| DB2 Version
|
DSN Schema Name
|
| 9
|
DSN8910
|
| 10
|
DSN8010
|
| 11
|
DSN8110
|
- Click
OK.
- From the
DB2 Connection drop-down list, select the DB2 data source that you specified when creating your connection with the Manage Connections tool.
Depending on your DB2 database connection specifications, you might be prompted for a user ID and password. If so, enter the
user ID and password you supplied when creating the DB2 connection.
- Click
Local. This sets the Extract Schema tool to save the generated schema extract file to the directory specified by the
Local HCOSS Directory HCOSS option.
- On the
Select schema(s) to extract list, check the box that corresponds to the schema that corresponds to your version of DB2.
- In the
Table Row Count group, select
Estimated using schema statistics. This option estimates the table row count based on the most recent statistics available, and returns results faster than
the other option,
Both Estimated and Actual (COUNT(*)), which additionally performs a COUNT_BIG(*) on the selected table or tables.
- Click
Extract. This initiates the extract schema process, writing the
schema-name.hcodbs XML file, and takes you to the
Results tab. Here you can see the results of the extraction.
Review the
schema-name.hcodbs File
- From the HCO for SQL Server interface, click
Options.
- Note the path specification for the
Local HCOSS Directory. The default is
%ALLUSERSPROFILE%\Micro Focus\Enterprise Developer\hcoss.
- In a text editor, open the
schema-name.hcodbs
file, located in the
Schemas subdirectory of your local HCOSS directory.
- Review the XML representation of the downloaded schema.
- When you have finished looking at the file, close the text editor. Do not save any changes if prompted.
