Session-desc-length is a four-byte field: when the Varying-length-request option is “N” it contains the number of bytes addressed by the Session-desc-pointer field; when the Varying-length-request option is “Y”, Session-desc-length is ignored.
Use of Session-desc requires a Connect-type setting of “C”.
Session-desc-length 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, Session-desc-length is ignored.

The value must be positive. The sum of this length and the length used for Workload-pointer must be less than or equal to one of the following values:
|The maximum value is approximately. . .||If Maximum-parcel is set to...|
|2,147,483,602||H, and Teradata Database supports ExtendedResponse, as indicated by the DBCHQE Extended-response-support query.|
The actual maximum may vary slightly with the version of Teradata Database being used; the value may be obtained using the DBCHQE CLIv2-limits query.
