Determines whether the driver creates the internal files required for a relational view of the native data when establishing a connection.
Valid Values
no | notExist
Behavior
If set to no, the driver uses the current group of internal files specified by SchemaMap. If the files do not exist, the connection fails.
If set to notExist, the driver uses the current group of internal files specified by SchemaMap. If the files do not exist, the driver creates them.
Notes
The internal files share the same directory as the schema map's configuration file. This directory is specified by the value you enter for the SchemaMap connection property.
You can refresh the internal files related to an existing relational view of your data in one of two ways. First, you can use the SQL extensions Refresh Map or Reload Map. Refresh Map runs a discovery against your native data and updates your internal files accordingly, while Reload Map refreshes the internal files to integrate configuration changes without running a discovery. Second, you can refresh these internal files by launching the DataDirect Schema Tool and opening the corresponding schema map configuration file. When an existing schema is opened with the Schema Tool, the Schema Tool automatically compares the content of the schema configuration file to a snapshot of the data on the wire. When new native objects are detected, the Schema Tool displays the newly detected objects by highlighting them in a hierarchical view of the native data.
