Purpose

Determines whether the driver creates the internal files required for a relational map of the native data model when establishing a connection.

Valid Values

NotExist | ForceNew | No | Session

Behavior

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.

If set to ForceNew, the driver deletes the group of internal files specified by SchemaMap and creates a new group of these files at the same location.

Warning: ForceNew causes all views, data caches, and map customizations defined in the current schema map to be lost.

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 Session, the driver uses memory to store the internal configuration information and relational map of the native data model. After the session, the view is discarded.

Notes

  • The internal files share the same directory as the SchemaMap configuration file. This directory is specified with the SchemaMap connection property.

  • You can refresh the internal files related to an existing relational view of your data with the SQL extension Refresh Map. Refresh Map runs a discovery against your native data and updates your internal files accordingly.
