Chapter 7: The DataServer Tutorial Adjust schema utility The Adjust Schema utility allows you to compare your MS SQL Server Schema holder information with the original OpenEdge database, updating any OpenEdge Attributes in the schema holder. These attributes include field names, labels, help, validation expressions and messages. You must be connected to the OpenEdge database and the schema holder that you want to compare to before running this utility. To adjust your schema: 1. Select the utility from the Data Admin Tool→ DataServer→ MS SQL Server Utilities→ Schema Migration Tools→ Adjust Schema. The following screen appears: If you leave the **all** in the Files To Compare section, all objects are compared and the changes are made. If you only want to compare certain objects, you must enter the information in the following format: ;; For example: customer,order;next-order-num,next-cust-num;custview,ordview 2. Select OK. All of the objects that are compared will be displayed on screen as they are processed. 302 OpenEdge Data Management: DataServer for Microsoft SQL Server
Delta df to MS SQL Server Incremental Schema Migration utility Delta df to MS SQL Server Incremental Schema Migration utility The Incremental Schema Migration utility allows you to migrate schema changes from OpenEdge to a MS SQL Server database. For example, in the process of developing an application in ABL that you will migrate to MS SQL Server, you might want to make and test schema changes in the OpenEdge database that you want reflected in the MS SQL Server database. The utility reads an OpenEdge delta.df file that has been created using the standard incremental dump procedure. and creates a delta.sql file that contains the SQL DDL for making the changes and a delta.df file. You can then load the delta.df file into the schema holder. You can then apply the delta.sql file to the MS SQL Server database to complete the migration process. Note: You do not make schema changes directly in the schema holder, which must remain synchronized with the MS SQL Server database. The utility uses the schema holder to determine what the MS SQL Server definitions are. To run the Incremental Schema Migration utility: 1. From the Data Admin main menu, choose DataServers→ MS SQL Server Utilities→ Schema Migration Tools→ Generate Delta.sql OpenEdge to MSS. The following dialog box appears: OpenEdge Data Management: DataServer for Microsoft SQL Server 303
