Memory Management Tips

How to Reconfigure Solaris 11 Kernel Zones Resources Lesson 4 of 4


>> Mick:  One last thing. Just to remind you that I went through on the previous tutorial, you may need to put a little kernel tweak in to set a limitation on the ZFS ARC cache. And there’s some information here just as an example.


You would create a file, a text file in etc system.d. Any text filename will do containing that parameter. Set user_reserve_hint_pct= and the percentage of RAM that you want to make sure is available for your applications. Otherwise, ZFS tends to use a lot of free memory and may not release it quickly enough and cause a few headaches with memory management.


There’s a very elaborate and detailed document available from Oracle. Log in to My Oracle Support and look for that Doc ID 1663862.1 and that will explain everything in fine detail.




Thank you very much for looking at this tutorial. I hope you’ve learned a little bit from it and join us for another tutorial a bit more down the line where we’ll be looking at kernel zone shared storage. And this has been brought to you by SkillBuilders who are experts with Oracle Databases. Thank you very much indeed.
