The DataServer Tutorial Migrating an OpenEdge database to MS SQL Server 7–20 The DataServer for MS SQL Server supports the OpenEdge DB to MS SQL Server utility that allows you to migrate an OpenEdge database to a foreign data source through the use of the MS SQL Server DataServer. While the DataServer makes a data source conform to an OpenEdge database, this utility provides compatibility in the opposite direction. It copies an existing OpenEdge database schema into a target data source. The OpenEdge DB to MS SQL Server utility performs the following tasks: • Creates objects in the target data source • Creates the schema holder and schema image • Optionally populates the data source by dumping and loading the data from the OpenEdge database The MS SQL Server data source that you create with this utility is a basis for an application database. Before deploying your new data source, you might want to make manual adjustments to take advantage of additional MS SQL Server features that are not supported by the migration utility. The OpenEdge DB to MS SQL Server utility requires a local OpenEdge database. Preparing a data source for the utility The OpenEdge DB to MS SQL Server migration utility translates definitions for OpenEdge objects into an SQL DDL script that loads into your target data source. It automatically makes adjustments in the target data source in order to provide the functionality of the OpenEdge and target systems. When you use the OpenEdge DB to MS SQL Server utility to make a MS SQL Server database compatible, it converts arrays by using one column in the MS SQL Server database for each extent of the OpenEdge array. The utility generates names for the columns that it adds to a table in a target data source using the format field–name##extent–number. For example, an OpenEdge field called monthly–amount with an extent of 12 will have 12 columns in the data source with names such as MONTHLY_AMOUNT##1 through MONTHLY_AMOUNT##12. 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.
Migrating an OpenEdge database to MS SQL Server 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: Table 7–5 describes the information for which you are prompted to enter. Table 7–5: OpenEdge-to-MS SQL Server Conversion utility (1 of 3) Interface element Description Original OpenEdge Database Accept the default value. If you are using suggested OpenEdge database name, the default is sports. Connect parameters for OpenEdge Name of Schema holder Database 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. 7–21
