I'm using VMware vCenter 6.0 on Windows server 2012 R2 and I'm looking for a way to decrease RAM usage of it. In previous vCenter versions there were options to change # Maximum Java Heap Size in C:\Program Files\VMware\Infrastructure\Inventory Service\conf but in this version those files aren't available. I only could find C:\Program Files\VMware\vCenter Server\invsvc\wrapper\conf\wrapper.confin version 6 and the WRAPPER.CONF file didn't contain # Maximum Java Heap Size (in MB). it's only for inventory service, I couldn't even find that file for tomcat server.

so my questions are

  1. where can i find those files in vCenter ver 6.0?
  2. Is there any alternative to modifying WRAPPER.CONF file for decreasing RAM usage?
  3. which non-critical services of vCenter 6.0 can I disable in order to increase overall performance but yet be able to use basic features of Web client?

    You should really be using the vSphere vCenter Server Appliance (Linux) these days... – ewwhite Jul 15 '15 at 19:54
  • Well there are many reasons like It's harder to manage a Linux server than Windows server 2012, at least for me, I can manage most parts of the OS by myself but in Linux I don't have enough knowledge, and I can't install VMware Horizon View Composer on the same server. There should be some ways to manage it in Windows server too. also the minimum requirement RAM for vCenter Server appliance is 8 GB but I read people could manage to decrease the RAM usage to 4 GB in vCenter 5.5, so its scalability is much higher. I need to do the same to vCenter v 6.0. – user299093 Jul 15 '15 at 20:05

    The whole point of the VCSA is that you don't HAVE to do anything with the linux side of things, zero - it just works as an appliance! It really does make sense to drop the Windows version (and the .net client) as soon as possible as they're 'going away' soon enough. – Chopper3 Jul 15 '15 at 20:17

    A) Yes, they want to move away from all Windows-based services, and before v7 too, already the Windows version of vC with the built-in-DB is already less capable that VCSA (though that might actually be NDA sorry, I work closely with them) and B) I have to admit I've never compared them - even during VCIX-exam-prep - that's how unlikely I am to deal with the Windows version :) Most people don't care because their hosts have easily enough memory to make any tiny variation insignificant - are you very memory constrained? if so that's not exactly best-practice. – Chopper3 Jul 15 '15 at 20:43
