70 CICS Transaction Gateway V5 When using the CICS TG for z/OS (using either the Gateway daemon or WebSphere Application Server), for security reasons this user ID and password should be verified with RACF before the EXCI request is made. – LOCAL: Specifies that a user ID will not be flowed by the remote system, and instead only the link user ID (if specified) will be used. If no link user ID is supplied, then all requests will be run under the CICS default user ID as specified in the DFLTUSER SIT parameter. For more details on CICS security, refer to Chapter 6, “CICS TG security scenarios” on page 99. 4.2.2 EXCI SESSIONS definitions For each EXCI connection definition, it is necessary to use a SESSIONS definition to define the parameters of the SESSIONS being used. Figure 4-3 shows the SESSIONS definition used for our connection CTG5 to our CICS TG region SCSCTG5.

The key parameters in the SESSIONS definition are: ► CONNECTION Associates this SESSIONS definition with the CONNECTION name CTG5. ► PROTOCOL Indicates the type of sessions to be used for an intercommunication connection. Sessions used by EXCI must specify EXCI for the protocol. ► RECEIVEPFX Specifies a one- or two-character prefix that CICS is to use as the first one or two characters of the receive session names. CICS creates the remainder of the four-character names from the alphanumeric characters A through Z, and 1 through 9. These two- or three-character identifiers begin with the letters AAA, and continue in ascending sequence until the number of session entries reaches the limit set by the RECEIVECOUNT value (in our example C5AA, C5AB, C5AC, and so on). The default receive prefix is (
