CICS Transaction Gateway V5 The WebSphere ... - IBM Redbooks

86 CICS Transaction Gateway V5
The fields relevant to ECI on the TCPIPSERVICE definition are as follows:
PORTNUMBER 2 The port on which the TCP/IP service listens.
PROTOCOL The protocol of the service. This should be ECI.
TRANSACTION The transaction that is run on CICS to handle the
incoming ECI requests. This is CIEP for ECI.
BACKLOG The number of TCP/IP connections that are queued in
TCP/IP before TCP/IP starts to reject incoming requests.
We set this to 100.
IPADDRESS The dotted decimal IP address on which the
TCPIPSERVICE listens. Since we had two IP stacks, we
specified ANY so that the CICS TCP/IP listener would
listen on both addresses.
SOCKETCLOSE Specifies if, and for how long, CICS should wait before
closing the socket, after issuing a receive for incoming
data on that socket. For ECI connections, we recommend
NO. This will ensure that the connection from the Client
daemon always remains open.
ATTACHSEC Specifies the level of attach-time security required for
TCP/IP connections to CICS Clients. For testing
purposes, we specified LOCAL, which means that CICS
does not require a user ID or password from clients.
We installed our TCPIPSERVICE definition using the command:
CEDA INS TCPIPSERVICE(PJA1TCP) GROUP(PJA1GRP).
We used the command CEMT I TCPIPS to display the active service (Figure 5-4).
