Mysterious Double Instance Hampering Performance - I study the existing code base. Confer with a colleague. Then I determine the optimal plan to change the functionality to load only a slice of all the dat...
Turns out my normal backup was also out of the office. That's okay. I trained the new guy on this system. Unfortuantely he told the managers that he knew nothing about the operations. Fail. I guess I trained him up but he did not use that knowledge. So he forgot it all.
Today I was scheduled to give a one hour session on the system. I did so. Took around 30 minutes to give a high level overview plus a hands on demonstration on how all the pieces get run. Then a manager asked me to prep the audience to respond to problems. Another manager asked that I give them the steps to "reset the data".
Unfortunately the only way to get familiar with the system is to get your hands dirty. You got to resolve a bunch of trouble tickets. Only then will you get the chance to dig deep and understand what the heck is going on. That's how I learned. That's how my backup learned. And that's how everyone else is going to need to learn. Sorry. Once again there is no silver bullet here.
