Dynamic Reconfiguration

The dynamic reconfiguration (DR) feature of Sun Enterprise servers enables users to dynamically add and delete system boards, which contain hardware resources such as processors, memory, and I/O devices. Solaris Resource Manager keeps track of the available processor resources for scheduling purposes and appropriately handles the changes, fairly redistibuting currently available processor resources among eligible users and processes.

Because Solaris Resource Manager controls only the virtual memory sizes of processes, not the physical memory used by processes and users, the effect of a DR operation on memory has no impact on Solaris Resource Manager's memory-limit checking.
