At IDMS r17.0; there's a new SYSGEN TCPIP option; 'ADD TCPIP'. The IDMS r17.0 Release Guide in section 6.3.1

provides the following information as default settings.

   ADD TCP/IP                                                                   
      DEFAULT STATUS IS ON                                                    
      DEFAULT TCP_NODELAY OPTION IS OFF                                       
      DEFAULT STACK IS DEFAULT                                                
      MAXIMUM NUMBER OF SOCKETS IS DEFAULT                                    
      MAXIMUM NUMBER OF SOCKETS PER TASK IS DEFAULT                           
      PLUGIN MODULE IS RHDCD1IP                                               
      SERVICES FILE IS OFF   
     As to the INCLUDE/EXCLUDE STACKS spec information; typically the site's SYSTEM Administrator or       TCPIP staff would provide input on what to set these parameters to. 
      
      In order to verify the TCPIP SYSGEN definitions; from the Enter Next Task Code;       issue a 'DCMT DIS TCPIP' to display the TCPIP SYSGEN and SYSIDMS settings:

There are also these SYSIDMS parameters that control SOCKETS and there are more TCPIP SYSIDMS settings are described in the 17.0 Callable Manual,
section 13.2 SYSIDMS Parameter File - TCP/IP-Related Parameters.

 TCP/IP_MAXIMUM_SOCKETS=nnn  

nnn = Specifies the maximum number of sockets that can be created globally in the DC/UCF system.

 TCP/IP_MAXIMUM_SOCKETS_PER_TASK=nnn 

nnn = Specifies the maximum number of sockets that can be created by a single task in the DC/UCF system.
