Using OPTIME Security

To support CICS, an OPTIME field matches the TIMEOUT field described in IBM CICS documentation. The syntax follows.

TSS ADDTO(acid) OPTIME(hhmm)

OPTIME controls the period of time allowed before CICS considers a terminal user to be “timed‑out.” The action taken by CICS depends on a CICS parameter, SIGNOFF, which is specified in the TYPETERM definition. See the IBM documentation for more information about the use and setting of these fields.

CA Top Secret provides the OPTIME field to support IBM CICS TIMEOUT functionality. When the user signs on, CA Top Secret places the OPTIME value into the user's TCTTE. CICS then scans the idle time for each terminal. When OPTIME/TIMEOUT is exceeded, CICS will take action based on the TYPETERM SIGNOFF parameter associated with the user's terminal.

Adding a non‑zero OPTIME to DFLTUSER gives a default value for OPTIME to any user who does not have a non‑zero OPTIME already assigned.
