Cause
Resolution
It is possible to configure the driver to refresh the local map files upon connection using the "CreateMap" connection option.  The details of this connection option are below.  For more details, please see the Connect for JDBC Driver User's Guide.

CreateMap

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

Valid Values
forceNew | no | notExist

Behavior
- 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.
- 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 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.
*CreateMap was formerly CreateDB.

Data Source Method

Default
notExist
