Response Buffer Length - Call-Level Interface Version 2

Response Buffer Length

Usage Notes

The Response Buffer Length field specifies the desired length of the buffer in which responses received from the Teradata Database are made available to the application program.

Language	Variable Name
COBOL:	DBCAREA-RESP-BUF-LEN
C: DBCAREA.H:	resp_buf_len

Routine	Action Taken
DBCHINI:	writes
DBCHCL:	reads (CON; RSUP; IRQ; REW; ABT)

Used by	Action Taken
application program	writes

The value of zero indicates that DBCHCL is to use the default value from the SPB bytes for the Response Buffer Length. The application program may change the value in Response Buffer Length as shown in the following sections.

Using CLICON

When connecting one or more sessions using CLICON, regardless of whether extended response is supported by the server, the maximum response buffer size limit is:

~32K (for maximum_parcel='O')

~64K (for maximum_parcel='H')

After a session has been successfully connected, the maximum response buffer size limit is:

~32K (for maximum_parcel='O')

~64K (for maximum_parcel='H' when extended response support is not supported by the server)

~1M (for maximum_parcel='H' when extended response is supported by the server)
