    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

WCS: WCS Server Diagnostics Page

DateSaturday, April 30, 2011 at 12:18AM

I always enjoy speaking to knowledgeable Cisco TAC engineers. I recently was experiencing some VERY SLOW WCS server response. The TAC engineer enlightened me to a “Server Diagnostics Page”

 “I find it most successful to have multiple windows open to WCS at the same time, one of the GUI and one of the diagnostic page.  Navigate a page in the GUI, then change windows to the diag page and click Refresh.  Use the browser's File > Save As utility to capture a copy of the diag page while WCS is in pain, and send it in for review.  We'll take a look at what the Java threads are doing, and what tables they're interacting with, and know better what actions to take to address the latency.” --TAC
