Example with the right way :

help you fix your problem Since this sounds like you've already built everything and just want to automate it, here is an idea:
Set up a Quartz job to run every 2 hours. Example here Use Rhino to run your JavaScript inside the JVM. Example here. OTOH, you could translate your JS code to Java and just run it natively without Rhino. Take the output of the JS method and save it to the server.

like below fixes the issue This ended up being a very strange situation in the end and resolving a different issue ended up being what solved this one.
What turned out happening was there ended up being a scheduled task that was running at the exact same time that was forcing an IIS Reset. Well the IIS Reset would hit and while it was trying to start back up this process would attempt to upload a file. The upload would of course fail with the above error message because there ended up being nothing listening on port 80 while IIS service was starting.

Package refresh Model/data refresh (what you referred to as the first half of the process) Tile refresh (2nd half of the process) Visual container refresh

To fix the issue you can do According to source code of QuartzInitializerListener quartz was being shutdown but the waitOnShutdown flag is set to false, hence Tomcat didn't wait for quartz to finish before it shutdown so Tomcat decided that it had left threads running and complained.
Try to init the quartz:wait-on-shutdown to true in your listener configuration in addition to shutdown-on-unload property which default to true already (web.xml).
code :
 <context-param>
     <param-name>quartz:shutdown-on-unload</param-name>
     <param-value>true</param-value>
 </context-param>
 <context-param>
     <param-name>quartz:wait-on-shutdown</param-name>
     <param-value>true</param-value>
 </context-param>
