A non-unique UserID is one that is not associated to a single owner,
but instead can be used by more than one user.
LU assignment for non-unique UserIDs provides the following processing:
- LUs within the same FEPI pool are assigned uniquely to a non-unique user
UserID and left assigned to that UserID during invocation of potentially multiple
FEPI server adapters within the scope of a single executing business request.
- That multiple of these business requests can be executing concurrently
for the same non-unique UserID. The processing of each of these concurrent
business requests would and must be performed in separate and distinct CICS® Service Flow Runtime / BTS processes.
- The provision for LUs to remain assigned, (signed-on and in-session for
a specific unique userId) across multiple invocations of subsequent processes
that may require usage of that LU. This means the LU could remain assigned
to the user UserID on the CICS Service Flow Runtime Connection
file after the process is complete.
LUs are required to establish connections and sessions to CICS regions
and applications in modeled flows that contain FEPI Navigators. LU assignment
processing for non-unique UserID looks at processing requirements that arise
when non-unique UserIDs are used with CICS Service Flow Runtime.
Using LU assignment processing for non-unique UserIDs in your FEPI service
flows will determine how the CICS Service Flow Runtime server
run-time assigns LUs that are used to establish connections and sessions to CICS regions
and applications. See Run time processing of non-unique UserIDs using FEPI adapters for
a description of run time processing associated with LU assignments for non-unique
UserIDs .
