Purpose

This control enables users to specify whether CLI double-buffering is active or inactive. It overrides CLI’s System Parameter Block (SPB) two_resp_bufs entry for client response buffering.

Syntax



where the following is true:

ON
CLI’s double-buffering function is active.

If neither ON or OFF is specified in the command, BTEQ sets SESSION TWORESPBUFS to ON.

OFF
CLI’s double-buffering function is not active.

Usage Notes

The specifications for the SESSION TWORESPBUFS command always override the two_resp_bufs entries for double-buffering in CLI’s System Parameter Block (SPB). In general, use of double-buffering enables performance benefits that cannot be realized when using single-buffering. Therefore, BTEQ specifies a default of ON for this setting. For further details about CLI buffering methods, refer to the CLI reference manual.
