VCAP6.5-DCV Design Prep-Guide

I’ve been on VCAP6.5-DCV Design in end of April and I passed. The exam wasn’t easy. First of all, the best practices, white papers, books and other documents that I’d to go thru to be successful is tremendous. While, I’ve used many of those in my daily job, one way or another, it would take far longer to prepare If haven’t read any of them. Therefore, plan ahead and make sure you would have enough time to prepare, especially if you have no experience in architecture at all. Personally, the time took me to prepare was more than I anticipated.

Having everything ready let’s,

vCenter 5.5 service fails to start

Few days ago when I was preparing vSphere Self-Signed certificates article I found out that vCenter is down. I notice that vCenter 5.5 service fails to start with very “interesting” general error message which did not say much. I haven’t actually used my lab for while and I suspected that something went wrong with my Database. However, I checked all components, Databases, users, passwords and so on but I did not found anything. Only place, I haven’t looked yet was vCenter logs. In order to have fresh generated log and avoid searching in bunch of files I attempt to start service again with of course expected result, failure.

vCenter Self-Signed Certificates – Part 1

A month ago I had to upgrade one of our customers vCenter from 5.0 to 5.5. We were suppose to run pilot project and upgrade was part of the requirements.
