Very sad news on new Vmware Vsphere licensing.  Before version 4 Virtual infrastructure 3.5 one license was valid for 2 physical CPU server  now Vmware has announced that one license allows just one physical CPU. This means that the price increases a bit. The same applies to support…

You can easily monitor your Linux server load using built-in bash commands like

w

However, many folks prefer sysstat package (can be downloaded here, or from your Linux distribution site) package that provides even further performance monitoring utilities:

iostat

sar

vmstat

Login into your Linux server shell and execute the above commands. iostat, sar, vmstat can be run like

vmstat 1 10

Still many folks think that you need a dedicated IP for each site to gain the best SEO rankings.

While Oracle admin salaries are sky-high, SharpAdmin offers full Oracle database remote management at the fraction of the cost – around $250/month for one server instance. You can save thousands by just outsourcing Oracle database management.
