Info

Appendix A: Migration Issues Creating a schema holder The MS SQL Server Utilities are located under the DataServer menu option in the Data Administration. Progress Software Corporation recommends that you use the Create DataServer Schema option to pull in all the objects that your application needs. This will create the schema information as a database type of MS SQL Server instead of ODBC. After completing the schema pull, the schema needs to be adjusted to conform to OpenEdge behavior. To adjust the schema after completing the pull: 1. Connect to the original OpenEdge database. 2. Select the DataServer→ MS SQL Server Utilities→ Schema Migration Tools→ Adjust Schema option to fix the OpenEdge attributes needed for your application to run. You can specify the entire schema holder or specific objects. 334 OpenEdge Data Management: DataServer for Microsoft SQL Server
Modifying your application Note the following considerations and plan, as needed: Modifying your application • The DataServer for MS SQL Server supports the same functionality as the DataServer for ODBC. Therefore, you do not have to change your application. However, if you used any reference to DBTYPE as ODBC, you will have to change these to MS SQL Server. • Determine your application needs and goals before changing INTEGER data types to INT64 data types in applications. Not all INTEGER data types will necessarily require the additional bit size, nor will wholesale changes in data types necessarily work efficiently with other interfaces to ABL. To review additional considerations about determining when to use INT64 versus INTEGER, see Release 10 ABL Data Types Web paper available at the Web paper category of the PSDN Web site located at http://communities.progress.com/pcom/community/psdn.
