Basics of KeepAlive

Challenge:

If your Sitecore is restarting periodically? and if you see following log entry in your log file

“HostingEnvironment initiated shutdown”
All your cache is being flushed?
If your Sitecore instance sits idle and your cache gets flushed automatically as your Sitecore instance
got restarted?

Then probably this post is for you!

Solution:

We were also struggling to solve above issues. And the pattern what we observed is that — If We keep system idle it restarts itself. This lead us to following solution:


http:///sitecore/keepalive.aspx
true/false

Basically the URL pointed in above configuration was wrong, we changed it and it started working fine!

You must be curious to know what it does?

The Sitecore keep alive agent, required to prevent a restart of the Sitecore web application during long periods of inactivity

In short this agent requests provided URL in one hour interval.  which will keep your worker process alive! [Updated – thanks to Sudeep]

Simple right? But very effective!

Long live worker process! 🙂

    “In short this agent requests provided URL in one minute interval.”

    Just correcting one small mistake, it’s one hour, not one minute
