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

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.
