(Optional) Define Common INET PFS

Define Common INET (CINET) Physical File System (PFS), if not already defined.

Before you begin

If you want to run multiple z/OS Communications Server TCP/IP stacks concurrently, you must use the Common INET (CINET) configuration.
Note: Setting up and managing several TCP/IP stacks on z/OS is a separate task that is not directly related to security or encryption setup.
For more information, see the following topics in z/OS Communications Server: IP Configuration Guide: Common INET PFS and Specifying BPXPRMxx values for a CINET configuration.

About this task

If not already defined, you must add values for a CINET configuration.

Procedure

  1. Add the following statements to USER.PARMLIB(BPXPRM01): 
    MAXFILEPROC(20000)
SHRLIBRGNSIZE(134000000)

FILESYSTYPE TYPE(CINET) 
            ENTRYPOINT(BPXTCINT)
NETWORK DOMAINNAME(AF_INET)
        DOMAINNUMBER(2)
        MAXSOCKETS(20000)
        TYPE(CINET)
NETWORK DOMAINNAME(AF_INET6)
        DOMAINNUMBER(19)
        MAXSOCKETS(35000)
        TYPE(CINET)
SUBFILESYSTYPE NAME(TCPIP)
               TYPE(CINET)
               ENTRYPOINT(EZBPFINI)
SUBFILESYSTYPE NAME(TCPIPB)
               TYPE(CINET)
               ENTRYPOINT(EZBPFINI)
  2. Perform an IPL of the system.
