Use Case Realisation in UML

-
This is a sample of a use case realisation (design-level) for a use case “View the Dashboard”.
The implementation uses ASP.NET MVC and the design is documented in the following UML diagrams.
This is an experiment whereby I produced the design in UML for a new developer to implement the use case.

The following Sequence Diagram documents the initial web request to display the empty Dashboard.
Initial Request
The following Sequence Diagram documents subsequent web requests to display the search result.
Retrieval Request
The next Sequence Diagram specifies the implementation of DashBoardCntrl::retrievePlanListFromCache.
DashBoardCntrl__retrievePlanListFromCache
The final is the View-Of-Participating-Class (VOPC) diagram for this use case realisation.

I originally had a great deal of difficult reconciling the differences amongst ITIL Change Management, Incident Management, and Problem Management.

Similarly, I wanted to differentiate the various categories of changes (Standard, Emergency, Normal) using an easy to understand & self-explanatory manner – a UML Activity Diagram!

Apache Web Server Troubleshooting

How to troubleshoot Apache Web Server? A few standard commands to know by hard: To confirm the modules that are or will be loaded in Apache: apachectl –M [-f <conf filename>] To check the virtual host load pattern: apachectl –S [-f <conf filename>] To test a httpd.conf file: apachectl –t [-f <conf filename>] To maintain the http server: apachectl start|stop|restart To start with a specified configuration file: apachectl –f <conf filename> Create a minimalist httpd.conf. Something like: Listen 80 ServerName myserver.com:80 ServerAdmin admin@myserver.com #ServerRoot " . " ServerRoot " /usr/local/apache2 " User nobody Group nobody #DocumentRoot " ..\wwwroot " DocumentRoot " /home/data/html " ErrorLog " logs/basic_apache.log " LogLevel debug #LoadModule log_config_module modules/mod_log_config.dll LoadModule log_config_module modules/mod_log_config.so <IfModule log_config_module> LogFormat " %h %l
