I know it is only 29 characters, but here is the Oracle documentation on the ORA-0972 error
Oracle Product Document Library (C) Oracle Corporation
Manual: Database Error Reference: A90202-02
ORA-00972 identifier is too long
Cause: The name of a schema object exceeds 30 characters. Schema objects are tables, clusters, views, indexes, synonyms, tablespaces, and usernames.
Action: Shorten the name to 30 characters or less.
Hope that helps.
