Configuration Parameters › CONFIG Member Parameters › TCPSSNDB

TCPSSNDB

TCP/IP Socket option SO_SNDBUF. This parameter specifies the buffer size for sends. Use 0 for the default size provided by the socket implementation. The value for TCPSSNDB can be smaller than the value for TCPTBUF. Used for TCP/IP transfers only.

0 to 256000

Specifies the buffer size for sends for TCP/IP transfers.

Default: 64

Notes:

• A value in the range 1 to 250 is interpreted as K bytes while 251 and above is interpreted as bytes.
• This value is rounded to the next highest 4K.
• Socket options affect the way CA XCOM Data Transport uses the TCP/IP stack implementation.
• The maximum value allowed for this parameter may differ from one z/OS version to another. If errors occur during server startup, then the value of this parameter will need to be lowered.
