48 == Deployment ==
49
50 * Stop your Tomcat
51 * In case of an **update**, delete old ONYX war-files and dirs from ${TOMCAT_HOME}/webapps
52 * It might be useful to clear the work and temp directory of the Tomcat Server:
53
54 {{code language="powershell"}}
55 rm -rf ${TOMCAT_HOME}/temp/* ${TOMCAT_HOME}/work/*
56 {{/code}}
57
58 (% class="_mce_tagged_br" %)
59 * Copy the onyx-player-**X.X**.war to ${TOMCAT_HOME}/webapps
60 * Start your Tomcat
61 * Open the following URL in your browser: [[http:~~/~~/localhost:8080/onyx-player-X.X/demo>>url:http://localhost:8080/onyx-player-X.X/demo||shape="rect"]]
62
63 == Configuration of additional features ==
64
65 === Show example tests on your ONYX Player start page ===
66
67 * Save the zip-files in /src/main/resources/tests
68 * Set showinternaltests to true (onyxplugin.config.xml)
69
70 === Provide an upload functionality for tests on your ONYX Player start page ===
71
72 * Define a folder in onyxplugin.config.xml where uploaded tests should be stored: <uploaddir>/tmp/</uploaddir>
73 * Note that this folder must exist and be writable or it must be allowed to create it.
74 * You can upload tests on your ONYX Player start page and access the tests directly via a static URL.
75
76 === Install MAXIMA, if you like to use calculations ===
77
78 * Installation on RHEL/Fedora/CentOS:
79
80 {{code language="powershell"}}
81 sudo yum install maxima
82 {{/code}}
83
84 * Installation on Debian/Ubuntu/Mint:
85
86 {{code language="powershell"}}
87 sudo yum install maxima
88 {{/code}}
89
90 * Or visit [[http:~~/~~/maxima.sourceforge.net/>>url:http://maxima.sourceforge.net/||shape="rect"]] and download the MAXIMA files
91
92 === Save user results ===
93
94 * ONYX allows **saving user results on the hard disk** **additionally to the transmission to the LMS**. This may be useful in case results cannot be transmitted due to errors in the LMS or during the transmission process. To activate this function enter the tag (((
95 of the file onyxplugin.config.xml and adjust the indicated directory to your server. Tomcat needs a writing permission for this directory. The result files are sorted in a sub folder by date and will not be deleted. In case the result files are no longer required, deletion can be done only by administrators.
96 )))
97
98 {{code language="powershell"}}
99 <resultsdir>/tmp/onyxresults/</resultsdir> in the section <playerconfig>...</playerconfig>
100 {{/code}}
101
102 * You may configure ONYX Player to **automatically remove these result file copies after a certain time span**. The following option can be added to the configuration to activate this. Please configure a valid days number, after which all results older than this age will be removed. This is checked and executed once after ONYX startup and will run in a background task. If not configured, this is done after 30 days.
