For intrapartition TD queues with a trigger level greater than zero, CICS
derives the userid associated with the triggered transaction from the following
sources:
- The USERID parameter specified on the intrapartition transient data resource
definition (DESTFAC=FILE).
- The userid associated with the terminal (for queues that have been defined
with a destination facility of terminal) (DESTFAC=TERMINAL). This can be the
CICS default userid if no user is signed on at the terminal.
- The link userid on the connection definition (for queues that have been
defined with a destination facility of system) (DESTFAC=SYSTEM).
