code cache reporting in red

[CommunityUser]

Morning,

If you see code cache in red (80%),what java options do you use to correct/help this? If not, why not?

No help listed is right!  I found this article that does a fantastic job describing some options for this:

https://www.atlassian.com/blog/archives/codecache-is-full-compiler-has-been-disabled

It was a little unclear if you should just use this option without the ReservedCodeCacheSize increase:

-XX:+UseCodeCacheFlushing

However, determining this would require some experimenting.  You could add the flushing option and watch it over time, or go the lazy route and increase the size and add the flushing.

See -XX:ReservedCodeCacheSize=
