Reality is normally started automatically when the host system is powered up.
On UNIX, each version of Reality installed on the system can also be started up separately using the realstart command. For example, to start up Reality V14.0 manually, set your user environment to include the following:
REALROOT=/usr/realman/14.0 PATH=$REALROOT/bin:$PATH export REALROOT PATH
Then, in super-user mode, enter:
realstart
On UNIX, Reality is stopped automatically when the system is powered down in single-user mode. The stop script in /etc/init.d/reality is executed using killreal to shutdown the central daemons for all releases listed in the installed directory in /usr/realman and remove the message queues.
On Windows, Reality is stopped automatically when the system is shutdown.
On UNIX, a single version of Reality installed on the system can also be stopped in multi-user mode using the killreal command.
For example, to stop Reality Release V14.0 manually, set your user environment, as described above for starting Reality.
Then, in super-user mode, enter:
killreal
killreal performs a controlled and orderly shutdown.
Note: The UNIX kill command must not be used to remove the central or database daemons, as this will leave the message queue, shared memory etc. in an untidy state.
