Configuring the TCPIPSERVICE on CICS TS

The TCPIPSERVICE is a resource that defines the attributes of the IPIC connection, including the listening port and the IPCONN autoinstall user program, referred to as a user replaceable module (URM).

1. Use CEDA to define a TCPIPSERVICE; for example, SRV50889. These values are important:
   • The Group is set to the name of your CICS® group.
   • The URM is set to point to the default IPIC autoinstall user program, DFHISAIP.
   • The port number is set for incoming IPIC requests.
   • The protocol is set to IPIC.
   • The transaction is set to CISS.
   All other values can be left to default.

   CEDA  DEFine TCpipservice( SRV50889 )
    TCpipservice   : SRV50889
    GROup          : HOLLTCPA
    DEscription  ==> IPIC AUTOINSTALL
    Urm          ==> DFHISAIP
    POrtnumber   ==> 50889             1-65535
    STatus       ==> Open              Open | Closed
    PROtocol     ==> IPIC              IIop | Http | Eci | User | IPic
    TRansaction  ==> CISS
    Backlog      ==> 00010             0-32767
    TSqprefix    ==>
    Ipaddress    ==>
    SOcketclose  ==> No                 No | 0-240000 (HHMMSS)
    Maxdatalen   ==>                    3-524288
   

2. Install the CEDA definition.
3. Check that the TCPIPSERVICE is active. On CICS TS, issue the command:

   CEMT INQ TCPIPSERVICE

   Check these values:
   • The port number shown is correct.
   • The status shows "Ope" for open.
   • The protocol shown is Ipic.
   • The URM shows the IPCONN autoinstall program, DFHISAIP.
     For example:

     CEMT INQ TCPIPSERVICE
     STATUS: RESULTS - OVERTYPE TO MODIFY 
     Tcpips(SRV50889) Ope Por(50889) Ipic Nos Tra(CISS) 
     Con(00000) Bac( 00010 ) Max( 000000 ) Urm( DFHISAIP )
