Chapter 7: The DataServer Tutorial Table 48: Verify utility report (2 of 2) Database object Difference Category Field Decimals Retained 2 Field Description Retained Field Extent Severe Field Initial value Retained 2 Field Mandatory Retained Field Name in OpenEdge Retained Field Order Retained Field OpenEdge data type Retained 2 Field OpenEdge format Retained 2 Field Shadow-column Name Severe 1. When you update an index, it is identified as unique if it was defined as unique in the data source or the schema holder. 2. If the corresponding information in the data source is incompatible with the information in the schema holder, the affected fields are not updated. For example, if the data source data type is decimal and the OpenEdge data type is CHARACTER, the data type information is not updated. To verify a table from the Data Administration tool: 1. Access the Data Administration, if you are not already there, and select DataServer→ MS SQL Server Utilities→ Verify Table Definition. The following dialog box appears: Note: You should 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.) 272 OpenEdge Data Management: DataServer for Microsoft SQL Server
Verifying a schema holder 2. Type preselection criteria values into the fields if desired. These values preselect the data source objects that the utility uses to update the schema holder. By default, the wild card symbol (*) appears; it specifies that the utility uses all of the objects in the data source. 3. By default, the utility verifies objects in the schema holder that match objects in the data source. To check whether there are objects in the data source that are not represented in the schema holder, deselect the check box Verify only objects that currently exist in the schema holder. 4. There is a 32K limit on the contents of the verify report. Select Output differences to file if you anticipate a large volume of differences, or wish to save the report. The file that is produced will be named, +.vfy and will be written to the working directory. 5. Choose OK. A dialog box like the following example lists the objects and table information that you preselected: 6. Select the objects that you want to update, then choose OK. 7. To select tables by matching a pattern, choose Select Some. The following dialog box appears: Note that you can also choose Deselect Some to deselect objects, using the identical matching a pattern options to deselect objects so they are not included in the schema holder.
