The virtual address space of a process is the total size of the process. The working set of a process is the amount of physical memory currently allocated to the process. In most cases, in order to avoid excessive system page faulting the virtual address space for the Sybase IQ process(es) should be less than the physical memory of the machine.
To monitor virtual address space and working set:
Start the Performance Monitor.
Click on the + icon and select the Process object.
Select the first Sybase IQ instance.
Select the counters Virtual Bytes and Working Set.
