There are some parameters about the socket buffer in AIX.
sb_max
Specifies the maximum buffer size allowed for a TCP and UDP socket. Limits setsockopt, udp_sendspace, udp_recvspace, tcp_sendspace, and tcp_recvspace.
udp_sendspace Specifies the system default socket-buffer size for sending UDP data.
tcp_sendspace Specifies the system default socket buffer size for sending data.
udp_recvspace Specifies the system default socket-buffer size for receiving UDP data.
tcp_recvspace Specifies the system default socket buffer size for receiving data. This affects the window size used by TCP.
How to get it? Take the sb_max for example.
no -a|grep sb_max
How to get it? Take the sb_max for example.
no -p -o sb_max=20971520
