Subject Re: Dynamic Scalable Template issue
Date Fri, 04 Sep 2015 16:34:17 GMT
Ok. After rebooting the instance still no change after disabling globally. I modified all my
templates to remove ‘Dynamic Scalable’,  then I have to shutdown every instance and unselect
‘Dynamic Scalable’, then restart for it to be correct.

This may need to be looked at closer for a Windows/XenDesktop(XenApp) environment as MS SQL
will consume all the RAM windows sees.

My other question is why CCP 4.3 (which is certified for Citrix Ready for IaaS for XD) didn’t
have this issue until I upgraded to 4.3.0.2 in July. This feature was released in 4.2…..


Thanks for all the help.

I will reboot an instance that is out of prod and let you know the results.

Hosts rebooted two weeks ago. Any instance built with a template with Dynamic Scalable set
to yes, shows in XenCenter as min/max memory as what system offering is but has a Static Max
of 4x the RAM.
