NonStop AutoTMF Software Errors

Monitor Process Errors

The monitor is a fault-tolerant process pair designed to be continuously available. All

warning and error messages reported by the monitor are displayed on the monitor’s

home terminal or, if no home terminal has been configured explicitly, to the default

EMS collector. You must select a home terminal for the monitor that is well integrated

with the application’s operational environment and can be monitored along with all

other vital subsystems.

The home terminal for the monitor process is configured when the MapDB is created or

when the monitor is started. See the description of the CI commands CREATE

MAPDB, ALTER MONITOR and START MONITOR for details about configuring the

monitor.

The monitor activity can be logged to a file for cases where the monitor’s behavior is

under suspicion.

If the monitor process fails, the monitor produces a saveabend file and displays a

message and a stack trace on its home terminal. Always check messages on the home

terminal when a failure occurs.

CI Errors

The CI is the user interface to NonStop AutoTMF software. The CI is used to configure

and monitor the environment. The CI also features a series of utility commands such

as COPY, FILEINFO, LISTLOCKS (LL), and so forth.

The CI uses the runtime library like any other prepared application program. A defect in

the runtime library could therefore affect the CI.

If the CI fails, the CI produces a saveabend file and displays a message and a stack

trace on its out file, most often the user’s terminal.

Application Debugging Environment

Debugging programs is an important diagnostic tool. Debugging prepared programs is

no different than debugging regular programs. There are only the following minor

differences:
