Configuring the TCPIPService on CICS TS

The TCPIPService is a resource that defines the attributes of the IPIC connection, including the listening port.

Use CEDA to define a TCPIPService; for example, SRV50889. These values are important:

The URM is set to NO to prevent the default IPCONN autoinstall program from running.
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. The security section of the TCPIPService is not applicable for the IPIC protocol; security is applied in the IPCONN definition.

CEDA  DEFine TCpipservice( SRV50889  )
       TCpipservice  : SRV50889
       GROup          : HOLLIPIC
       DEscription  ==>
       Urm          ==> NO
       POrtnumber   ==> 50889     1-65535
       STatus       ==> Open      Open | Closed
       PROtocol     ==> IPIC      IIop | Http | Eci | User | IPic
       TRansaction  ==> CISS

       Maxdatalen   ==>                    3-524288

Install the CEDA definition.
Check that the TCPIPService is active. On CICS® TS, issue the command:
```
CEMT INQ TCPIPSERVICE
```
Check the following values:
- The port number shown is correct.
- The status shows "Ope" for open.
- The protocol shown is Ipic.
- The URM shows NO to state that IPCONN autoinstall is not permitted on this TCPIPSERVICE.
  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(NO        )
```
