Cause
This error occurs if a schema maintenance operation, usually a schema load, attempts to rename or renumber an existing deployed database file. This operation is not allowed, as it could result in loss of access to data. The most-common cause of this problem is a mismatch in the map file definitions between the user schema and the database control file.
This problem is likely to occur only when deploying new user schema files or loading a schema that has incompatible map file definitions.
Action
Ensure that map file definitions that are being replaced or modified in the operation that triggered this error are compatible with the existing definitions in the database control file.
You can use the JADE Database utility to obtain a list of the file name to number maps defined in the database control file, by selecting any of the common file-based operations. File names and numbers are listed in the list box for file selection.
