Installing and configuring Oracle Solaris 11 non-global zones is great, and as we have mentioned previously, it is a great technique that isolates and runs applications without disturbing other applications if anything goes wrong. Nonetheless, there's still a problem. Each non-global zone runs in a global zone as it were running alone, but an inconvenient effect comes up if one of these zones takes all resources (the processor and memory) for itself, leaving little or nothing for the other zones. Based on this situation, a solution named resource manager can be deployed to control how many resources are consumed for each zone.
