Chapter 5: Configuring the DataServer 9. Choose OK. When the DataServer connects to the MS SQL Server database, it reads information about data source objects. The following dialog box appears: You can select tables based on the object name, owner/library information, and qualifier. For example, you can specify A* in the Object Name field to list all the tables whose names begin with A or a. Note: Progress Software Corporation recommends that you do not specify an entry that consists exclusively of wild cards for each of the three entry fields in the dialog box. An entry that consists exclusively of wild cards might degrade the performance of the database when you perform a schema pull. (It will include system catalog files from the data source not typically included in user databases.) Check Default to OpenEdge DATETIME to automatically map MS SQL Server data types to the associated OpenEdge data type. If you have modified your client application to handle LOB data types, check Default to OpenEdge LOB for: CLOBs and/or BLOBs to map the OpenEdge LOB data type to MS SQL Server VARBINARY (MAX), IMAGE and FILESTREAM data types. For more information on mapping OpenEdge and MS SQL Server data types, see“Support for OpenEdge ABL BLOB data type” section on page 87. If you select Designate Primary/Clustered index as ROWID, you will get the warning “Existing ROWID designations may be overwritten by selecting this option”. If selected, and a given table has a clustered index and does not have the _PROGRESS_RECID field defined for it, it will be used as ROWID if it qualifies for ROWID selection. Qualification requires that the index be unique. This designation for ROWID takes precedence over any other options selected for the schema pull operation but does not overwrite a ROWID designation that is based on the presence of _PROGRESS_RECID. When the Select ‘Best’ ROWID Index is selected, this option provides a legacy option for selecting ROWID when the _PROGRESS_RECID column is not present in the table. When selected in conjunction with new process flow options for ROWID migration, this option plays a secondary role in the designation of ROWID indexes deferring to the Designate Primary/Clustered index as ROWID option as the first choice. This option searches for a viable index for ROWID when an _PROGRESS_RECID column does not exist and other process flow options do not render a viable index. For more information on mapping OpenEdge and MS SQL Server data types, see the “Support for OpenEdge ABL BLOB data type” section on page 87 and the “Support for OpenEdge ABL CLOB data type” section on page 86. 202 OpenEdge Data Management: DataServer for Microsoft SQL Server
Creating a schema holder 10. Choose OK. OpenEdge displays a list of the data source objects that you can include in the schema holder, as shown: If you specified all wild cards as your table-selection criteria, the list might also include system-owned objects, which you do not have to include in the schema holder. 11. Click the option appropriate to the action you want to perform: • Select Some — Displays the Select by Pattern Match dialog box on which you can specify object information used to select objects. • Deselect Some — Displays the Deselect by Pattern Match dialog box on which you can specify object information used to deselect objects. You can also elect to select and deselect individual objects by clicking and double-clicking on an object. An asterisk appears next to an object that has been selected; double-click an object to remove the asterisk and identify that the object is now deselected. 12. Choose OK after you have identified all the objects you want to include in the schema holder. The DataServer reads information about the objects that you select and loads their data definitions into the schema holder. The time that this process takes depends on the size and number of objects that you select. For each table selected, the DataServer attempts to select an index to support the OpenEdge ROWID. If an appropriate index does not exist, the DataServer issues the warning, Please check errors, warnings and messages in the file ds_upd.e. The ds_upd.e file lists the objects that do not support ROWID. You can change the DataServer’s selection of an index to support ROWID by using the Data Dictionary. See the “Defining the ROWID” section on page 311 for instructions. For additional information, see the “Indexes and sorting” section on page 65.
