12.6 Time synchronization
All computers within one network have to have the same time. Use the Control Room Configurator
Control Room ConfiguratorControl Room Configurator
Control Room Configurator to specify
which computer is to be the clock server for all other Apollo network computers. Just set the Clock Server prop-
erty in the Custom Properties of the master in the Apollo database to True.
Now all Apollo network computers can be synchronized and set to the same time
12.7 Log file
All status and error messages are written to a file in order to check the system. This log-file is located in the
folder ..\ApolloProject\LOG.
The general syntax is as follows:
<class> <node> <task> <stamp> <module> <function>:<text>
class One character
m (message)
v (verbose)
r (error)
node Name of the computer or his IP address
task Name of application
stamp time (dd.mm.yy hh.mm.ss.mmm)
module Name of the module
function: Name of the function
text message
The general file name of the log file is <yyyy><mm><dd>.<no>. It includes the current date and a number be-
tween 000 and 999.
The log-files of all computers of the Apollo network are merged in the log-file on the master (control computer
of the Display Wall).
The file size is limited to 20MB. When this size is exceeded, entries are deleted according the sequence of gen-
eration, first the oldest ones.
12.8 Security Provider
The Apollo security mechanism is based on AccessGroups and restricted objects. Apollo allows configuring an
individual permission for every AccessGroup of every object.
The AccessGroups are configured with an ASCII editor. The restricted objects are configured dynamically via the
Permission command available in the Remote Desktop and in the Layout Selector.
Apollo assigns permissions to AccessGroups and not to individual users. A user is identified by his Windows login
name.
A user can be assigned to multiple AccessGroups. In case the respective AccessGroups have different permissions
on an object, the user assigned to multiple AccessGroups has the most significant permission given to one of
these AccessGroups.
Without any specific assignment, as default every user is assigned to the AccessGroup Everyone.
