Tornado Tools Reference
Target-server identifiers are unique, and they are based on the name of the target board
(or an explicit alternate name supplied when the target server is launched) and the name
of the host where the target server runs. The two names are linked with the character @,
for example, targetName@serverHost.
This registry allows the Tornado tools to establish a connection with the target servers.
After accidental shutdown of the registry, recovery is done based on the data saved in
wtxregd.hostName. The data base file default directory is $WIND_BASE/.wind and can be
specified through the -d[irectory] option.
On UNIX hosts, it is advisable to include the daemon in the rc.local file of the host where
it runs for UNIX users, so that it starts and restores database automatically after a reboot.
On Windows hosts the Tornado registry can also be used through the wtxregd daemon.
Tornado installation adds it to your Automatic Startup if specified, or you can add the
command line to the Start>Programs>Startup utilities.

TORNADO REGISTRY SERVICE
Windows NT users can add the wtxregd service to the startup services. This addition to
the Windows registry is done while installing Tornado.
The Tornado registry service does not accept any command line options; it starts with the
registry default options.
Note that, if you install the Tornado registry as a service (on Windows NT), you will not
be able to use Tornado 1.0.1 tools with your Tornado 2.0 installation. For more
information, see Tornado Getting Started: Installing Tornado.
DETECTING DEAD TARGET SERVERS
The registry daemon automatically detects target servers that are not responding. It
dynamically removes target servers that are presumed dead from the registry queue. This
self-managing feature prevents you from having to manually unregister target servers
that are not responding (see TARGET SERVERS PING section for further informations).
Tornado tools need to know the host on which the registry daemon runs. The host name
of this machine or its IP address is published through the environment variable
WIND_REGISTRY.
RESTORING THE DATA BASE
After an registry shutdown, a recovery of the data base is done from the data base backup
file whose location has been specified by the -d option. (The default location is
$WIND_BASE/.wind.)
If the target servers registered on the same host as the registry are not responding at
restoration time, they will be removed from the registry queue.
