VM_IN_BYTES and VM_OUT_BYTES were too high in 11g,why

741444Mar 9 2011 — edited Mar 10 2011
I found VM_IN_BYTES and VM_OUT_BYTES were too high in 11g.
I ran select * from V$OSSTAT , and saw
VM_IN_BYTES 5.02045853336388E17
VM_OUT_BYTES 2.22505966581948E17
I ran SELECT * FROM DBA_HIST_OSSTAT where value >= 100000000000000000 and rownum<1000 order by stat_name; and saw
...
VM_IN_BYTES 1.02106633154393E19
VM_IN_BYTES 4.68272347425629E18
VM_IN_BYTES 1.65548805720707E19
VM_IN_BYTES 2.14278122328326E18
VM_IN_BYTES 1.0692337352256E19
VM_IN_BYTES 1.48877218811052E19
VM_OUT_BYTES 1.00680080339231E18
VM_OUT_BYTES 1.00227961158344E18
VM_OUT_BYTES 1.00347588023529E18
VM_OUT_BYTES 1.00321199744519E18
VM_OUT_BYTES 1.00810262508321E18
VM_OUT_BYTES 1.00150555537094E18
...

The environment is windows server 2003 x64, Oracle 11g, memory 6G.
I think these values for VM_IN_BYTES and VM_OUT_BYTES were too high and unreasonable.
Who can tell me why?
Thank you very much!
