5.4.9 System Control Graphical User Interface (GUI)

5.4.9        System Control Graphical User Interface (GUI)

            There are three main system controls identified for this thesis project offline email system which are a server computer, mail server and database synchronize as shown in Figure 5.7. Server computer status can be viewed through Uniform Server system tray menu. The server computer Status button is an additional option as an alternative to view the networking status of the server computer. Exit button is to close the System Control Graphical User Interface and did not affect server computer, mail server and database synchronize operation. Server computer system control was executed through a batch file. Server computer application script configured and placed in a Uniform Server folder.

            There is a single central control architecture for Uniform Server which is located in folder UniServer\unicon\main. All server control requests such as Unitray, batch files and Apanel are passed to this core for processing. The advantage of this core control is to reduce external scripts complexity. These core controls consist of four Command-line interface (CLI) scripts. CLI is a mean of interaction in the form of lines of text (command line) to issue a command to the program. These CLI scripts are split into two parts which are standard program and service. Standard program part has files for start-stop while service part has files install-uninstall service respectively. Apache and MySQL are a tracker file controlling the interaction between standard program part and service part as shown in Figure 5.8.

Start batch script (Start_Server.bat) implemented as shown in Table 5.15 and Stop batch script (Stop_Server.bat) as shown in Table 5.16.

Table 5.15: Offline Server Computer Start script (Start_Server.bat)

            Both script parameters for start_servers.php and stop_servers.php line configured with binary code 19 which include the control server for Apache, Mysql and Cron as reference to Uniform Server Binary Codes shown in Figure 5.1. "Start.exe" line is to start the UniTray while "unicon\program\unidelay.exe 10" line gives a ten second delay to allow text to be read [21].

Table 5.16: Offline Server Computer Stop script (Stop_Server.bat)

Mail server application script implemented as shown in Table 5.17. Both scripts which are “start_hmailserver.bat” and “stop_hmailserver.bat” placed in a mail server folder such as “…PEmailOffline\hMailServer\Bin”.

CLI script	Script filename
net start hmailserver exit	start_hmailserver.bat
net stop hmailserver exit	stop_hmailserver.bat

“Database Synchronize” start button will execute real-time synchronization application, “RealtimeSync.exe” which is located in a database synchronization application folder such as “…PEmailOffline\FreeFileSync”.
