I went to Pulse in Las Vegas this week. Pulse is IBM Tivoli's flag ship trade show and educational event for Tivoli technology. While there wasn't what I consider a huge amount of z specific content at the show, there were some good sessions on ITCAM and integration with OMEGAMON, response time monitoring, cloud computing, Linux on z, alert management, and other interesting topics.
If you didn't get a chance to go to Pulse, later this year there will be Pulse Comes To You, where IBM will take the event on the road. Here is a link to info on Pulse Comes To You. In the coming weeks check this link for more info:
