Re: WDSC vs SEU RE: Saving the System i: Fight Rather Than Switch

Yes, this was a management problem. They did not listen to our recommendations in the first place. I was able to tune the system to balance out the spikes, and set the business back on track.
And, of course, a batch compile is not the issue. Repeated batch compiles for spelling checks ARE - IMHO they are as bad as an interactive compile. Maybe not cause for termination - until the first program review :-)

  This is a management problem if they can't goose up the server to handle
  the increased workload. A program compiling in batch in a separate
  subsystem is not going to cause a lost order. An interactive compile is
  another story. Can we spell "termination for cause"?

    Steve,
Within the last 12 months, I had a customer whose System i was seriously underperforming. The fault was that their business had grown faster than 
    their server growth, and the disk arms were being overused. Their
    applications were all slow - accounts receivable and payable were
    delayed.
    In one case, payroll was looking to be impacted. And order processing
    was
very slow. All through this time, programmers were still compiling, and 
    thus, impacting the business. This was a real situation, and while the
    phone
order entry was slow, it meant that the people waiting to order were not 
    being serviced in a timely manner. They lost orders.

    Wouldn't it be ironic if some of those orders were lost because a
    programmer
    was compiling to check spelling mistakes?

    Trevor
