                            Operating System Notes

<> OS Notes
<> APAR IX71421 : A 15 second timer is used to timeout Time-Wait connections,
<> ... set no -o tcp_timewait=5 (5*15 > 60) guarantees at least 60 seconds Time-Wait value
<> vmtune -c 1 : Enable sequential write-behind, causes the pages to be committed to disk sequentially
