Controlling automatic ending of Multi-line WTO messages

If a program issues a multi-line WTO message but does not end the message by issuing an endline, the system will hold the message in a staging area until an endline is received. Unended multiline messages will not be delivered to a console until an endline is received. The system monitors unended multi-line WTOs and will detect when a time interval threshold has been exceeded. This threshold specifies the number of seconds that the system will wait before truncating an unended multiline WTO that has not received a connecting WTO. When this time interval threshold is reached, the system ends the message automatically.

To end a multi-line WTO message when it detects that no data line or endline has been issued for the message after an interval of 30 seconds, the system issues the following endline:

  MESSAGE TIMED OUT - MESSAGE COMPLETION FORCED

The default interval is 30 seconds. You can control the length of the interval by using AMASPZAP or IGWSPZAP to set a value from X'0001' to X'FFFF' (1 second to 65,535 seconds). To update the time interval, run either AMASPZAP or IGWSPZAP with the following input statements:

NAME IEANUC01 IEEUCMC
VER 01B8 001E               /* verify currently 30 seconds */
REP 01B8 002D               /* alter setting to 45 seconds */

IBM® recommends altering the value using a formal SMP/E ++USERMOD so that SMP/E can track the modification. Use the following statements to make the alteration using SMP/E:

++USERMOD(TIMEOUT)          /* USERMOD name of your choice */
++VER(Z038) FMID(HBB7750)   /* FMID of your system */
++ZAP(IEECVUCM),
NAME IEANUC01 IEEUCMC
VER 01B8 001E               /* verify currently 30 seconds */
REP 01B8 002D               /* alter setting to 45 seconds */
