The Lightweight Scheduler Service (LWSS), pronounced
“lew-ess”, is a simple Windows service developed to allow web
developers a quick and easy way to support their web-applications with an
independent and reliable logic processing service. Many web-applications need
processes to execute on timed intervals. Some developers choose to execute
threads within their web application context, but web servers such as IIS can
be configured to wipe out application pools at unknown intervals, thus closing
these threads. Developers need a way to keep their scheduled logic running
constantly outside of web server threads and the Windows task scheduler.
LWSS is based upon a simple plugin-based
architecture and can easily be extended to execute custom plugin libraries across
multiple sessions (a configuration for one specific web application). A
developer simply needs to install LWSS, develop and copy a compatible plugin
library assembly into the plugins sub-folder, configure the service session and
any plugin settings via the admin GUI, and start the LWSS service.
LWSS has some common configuration settings that are passed
to the plugin assembly including database connection string, and e-mail server
settings. This allows the developer to manage commonly utilized parameters
across multiple plugins.
Each plugin can be configured to execute at a given time of
day and/or on a specified per-second interval. The core process of LWSS
executes an execution check every second. For example, a plugin execution
interval can be set to execute every 30 seconds starting from the time the
service started. LWSS can determine the start time and then execute the plugin
every 30 seconds thereafter.
