The invoker is not the definer, <str>

  Explanation:  The RESTRICT_INVOKER option was specified at
  compile time to ensure ANSI semantic behavior.  This requires
  that only the same user who compiles a module (the definer) may
  be the user who executes it (the invoker).

  User Action:  Recompile the module.  If it is not important that
  ANSI semantics be maintained, do not specify the
  RESTRICT_INVOKER option; any user will be able to execute a
  program linked with this module.  If ANSI semantics must be
  maintained, make sure that the user who will be the invoker also
  compiles the program.  Alternatively, a module language
  AUTHORIZATION clause specifies who the definer is, and may be
  used by one user to compile a module for another.
