PWXSOMAXCONN Statement

The PWXOSMAXCONN statement specifies the maximum number of TCP/IP socket connections that a PowerExchange Listener uses to listen for work.

All

PWXSOMAXCONN=num_connections

For the num_connections variable, enter the maximum number of TCP/IP sockets connections that PowerExchange Listener uses to listen for work. Default is the SOMAXCONN value of the operating system. On z/OS, the default is 10.

PowerExchange uses the lower of the two values PWXSOMAXCONN and SOMAXCONN. To increase the TCPIP queue depth, and thus the number of sockets available to PowerExchange tasks, you must increase both the TCPIP SOMAXCONN value and the PWXSOMAXCONN value.
