Disk Sizing Tip
Even though disks haves gotten faster, bigger and cheaper, I find that it is usually always under-sized. Why is that? Probably because it is not understood, but another big reason is that it is not monitored. If you are a DBA you should insist that in addition to DB2 monitoring, that server CPU, Disk, Network and memory resources are monitored. I guarantee you that if you are not doing this now, when you institute it you will be surprised at what you find. There are many free software packages out there that you can use or ensure are used. A couple are Ganglia, MRTG, NMON, and CACTi. Only 1% of clients I have been to do any type of monitoring, except for the network because that is all that CIOs typically focus on. So, get moving.
