  • Prestart Jobs and Server Jobs

    In 2009, I wrote a blog article titled, Identifying Server Jobs, where I reviewed what server jobs are, how you identify a job as a server job and where you can find documentation on server jobs.

You can view and change your presetart job entries via the command interface or with the Navigator graphical interface.

There are many aspects to consider with prestart jobs; this blog post is the first in a series on the topic.

    Copy Performance Data using ACS IFS Tasks

    Two weeks ago I compared the IFS tasks between Navigator and ACS. One of the major advantages of the ACS interface is the ability to easily move files between partitions. This week, I want to review considerations for moving performance data to a different partition.
