NNO-00252

Error: NNO-00252: invalid administrative region parameter string value "string"

Causa: The server encountered an invalid administrative region parameter. This error will prevent the server from starting. The administrative region description is stored in the server's NAMES.ORA configuration file.

Acción: Make sure that the NAMES.ADMIN_REGION parameter in NAMES.ORA is correct. The NAMES.ORA file is automatically generated by the Oracle Network Manager, but administrators can edit the file at any time, introducing errors. If the file was never changed, contact Oracle Support Services.
