Info

Chapter 7: The DataServer Tutorial Constraint definitions first defined in your foreign data source can be added to your OpenEdge schema holder during a schema pull, but are read only. To extract the read-only constraints into your OpenEdge database for reusing on subsequent migrations, use the Generating Constraints from ROWID option. See the “Generating constraint definitions from ROWID” section on page 290 for information on generating constraint definitions from ROWID. Running the OpenEdge DB to MS SQL Server utility The OpenEdge DB to MS SQL Server utility runs in Windows with a DataServer accessing MS SQL Server through an ODBC driver. You can run the utility interactively from Windows or UNIX, or in batch mode. To run the OpenEdge DB to MS SQL Server utility interactively: 1. Create a target MS SQL Server. You must use an empty target data source when you run the OpenEdge DB to MS SQL Server utility. 2. Configure your ODBC driver to connect to your new target data source. 3. Start the OpenEdge client and connect to the OpenEdge database that you want to migrate to the target data source. Note: For a DBE (double-byte enabled) DataServer application, you must specify the Internal Code Page (-cpinternal) and Stream Code Page (-cpstream) parameters when you start the OpenEdge client. The values that you specify for these parameters must match the code page that the target data source uses. 4. From the Data Administration, choose DataServer→ MS SQL Server Utilities→ Schema Migration Tools→ OpenEdge DB to MS SQL Server. The following screen appears: Figure 24: OpenEdge to MS SQL Server Conversion dialog box 294 OpenEdge Data Management: DataServer for Microsoft SQL Server
Migrating an OpenEdge database to MS SQL Server Table 50 describes the information for which you are prompted to enter. Table 50: OpenEdge-to-MS SQL Server Conversion utility (1 of 2) Interface element Description Original OpenEdge Database Connect parameters for OpenEdge Name of Schema holder Database Accept the default value. If you are using suggested OpenEdge database name, the default is sports. Accept the default value, which specifies the current working database. Type myholder, or another schema holder name of your choice. Logical Database Name Type the name that OpenEdge will use to identify the MS SQL Server database. ODBC Data Source Name Type the ODBC Data Source Name you used when registering the data source. Username Type the user ID for MS SQL Server. User’s Password Type the password of the user. Connect parameters See Chapter 6, “Connecting the DataServer,” for connection parameters. MaximumVarchar Length By default, the maximum size of the VARCHAR data type is 8000. The text data type is greater than 8000. If you enter a value that is less than 8000, the text data type will be used when a character field display format or width is greater than the value you have entered. NOTE: When Use Unicode Types is selected, NVARCHAR maximum length is 4000 by default. For UTF-8, because characters can use up to four bytes, only 2000 characters are guaranteed to fit. Codepage Must be the OpenEdge name for the code page that the data source uses. Use UTF-8 if Unicode support is desired. Collation Accept the default value. Insensitive Accept the default value to retain case insensitivity. Load SQL Leave this box selected to have the generated SQL script loaded into the data source.
