Refresh‑cached‑data specifies whether response data previously processed by CLIv2 can be re-used or must be reread from the Teradata Database.

This option would not be used by a normal application. It is intended only for diagnostic use.

Refresh‑cached‑data exists only when DBCHINI had been called for a DBCAREA with Total‑length set to at least 640 (that is, the returned DBCAREA Level value is at least 1). For a smaller DBCAREA, Refresh‑cached‑data is ignored.
