Diane’s Midway Update

Posted by Diane Tam on 2010/03/01

The term started off with an earlier Code Sprint kickoff than last term and this definitely helped get things in motion much quicker and allowed us to address problems much earlier on which I found was most helpful this term as our team ran into a series of dependent environment setup issues that delayed a lot of the work.  The goals and requirements of the project were fairly vague at first, but despite these early setbacks, I found that the team I am working with this term (compared to my last term with UCOSP) is a lot more self-driven and willing to communicate, ask questions, keep each other updated and help each other out.  Combined with our two weekly meetings, everyone’s efforts is a lot more visible and as a result, the progress of the project is easier to track and manage.  However, this is also due to the help we have gotten from our project leads from IBM.  They are always available to answer our questions and help put us in the right direction, thus enhancing our learning experience with the project.

In terms of the progress of the project, we had tentative deadlines set by the team and we have been able to use this to guide us fairly well through the term so far.  We have had to make some adjustments to deadlines here and there because we either underestimated the amount of work or ran into some unforeseen problems but I believe that’s all part of the learning process that goes along with project estimations and actual progress.  From my perspective, we are right on track.  We’ve managed to experiment with some database scenarios and integrate a graphical indicator to help monitor server side activity.  From this point on, progress should be much more fluid as we have a good base to work with now and are able to move on to refining the scenarios and graphical indicators to be more useful to the end user.

In terms of things to improve on from now until the end of the term, as we have experienced in the first part of the term, I believe we need to learn to plan a little better so that we can account for unexpected problems more efficiently, perhaps do a little more research before jumping in and setting hard goals.  Also, despite the fact that there is a lot of communication within the team, there is always the opportunity for miscommunication as well which has occurred in some instance where members ended up doing other member’s work.  With better communication, these problems may be avoided.

Code Sprint Jan 15-17 Overview:

http://ucosp.wordpress.com/2010/01/17/code-sprint-day-1-2-data-server-flight-simulator4/

http://ucosp.wordpress.com/2010/01/17/day-3-database-flight-simulator/

Overview:

One of the major long term goals for the Technology Explorer for IBM DB2 has been to provide an environment similar to a flight simulator for Database Administrators.  Pilots used to learn to deal with potentially dangerous and stressful situations in a real place.  This was risky and expensive.  Pilots today learn to deal with system failures and extreme conditions on flight simulators.  DBAs still develop their experience on live multi-million dollar production systems.  They could develop skills and confidence faster and more safely on a simulator.

Over the past few years the Technology Explorer for IBM DB2 team has built all the base components to create this simulator as part of our open source project.  The next step is to pull the pieces together into a viable simulation.  The team will use the existing open source building blocks to simulate a stable production system and then disrupt it with a number of planned or unplanned problems.  The system will then walk the DBA through problem recognition and resolution.

Goals for the project would:

  • Extend the existing framework to simulate database management problems
    • Simulate DB2 in production
    • Create a disruption of the system, for example a hard drive failure, lock contention, or excessive workload
    • Guide a DBA to identification and resolution of the disruption
  • Develop at least one example of a problem simulation

Languages:

PHP, JavaScript, Prototype js library, AJAX, dynamic web pages, HTTP protocol (the impact of it being a stateless system and what has been done to keep memory between requests on both the client and server sides)

Code Sprint Aftermath

Posted by chancancode on 2010/01/18

I’d like to thank Greg, all the mentors/organisers and the nice people from IBM (especially Matthew) for everything they have done for us. They have obviously put lots of effort and their spare time into this and I think we should all give them a big round of aplause.

So.. the code sprint is now officially over.. and here is what I think..

What I liked:

  • Having the chance to meet everyone before we actually start coding turns out to be extremely valuable. It turns out to be a non-trivial task to setup a communication channel that works for everyone in a team consisting of Windows, Linux and Mac users. (We ultimately decided to go for Skype for basic IM/conferencing and DimDim for more sophesicated meetings that involves screen sharing)
  • Matthew and some of this colleagues from IBM started the TE (the basic component of our fligt simulator) as a side project at IBM, so there are practically no documentation available. Therefore meeting with him in person is the single best way to learn about this framework that he built.
  • Toronto is a really cool city (in both senses)
  • Of course, the beds at holiday inn is very nice.

Not so much:

  • John already brought this up in the debreifing meeting – because we were away for the first day, we kinda felt “seperated” with everyone else
  • It is not very clear what this project is about from the description posted online, so the project turned out to be quite different than what everyone have in mind
  • Due to the “hobby” nature of this project, the pieces that we have to build on were not very well tested, and we bumped into a lot of technical difficulties as we were trying to set it up on our own machines. We still do not have a fully working base system by the end of the code sprint, so the development work could be quite challenging

That being said, the sprint was still an awesome experience – we get to meet lots of new people.. had lots of free food.. plus we get a free trip to Toronto! That alone has made taking the course worth while. We have a great team @ flight sim, so I’m sure we’ll deliever some really cool stuff by the end of the semester!

Keep it up guys!

Day 3: Database Flight Simulator

Posted by Michael Man on 2010/01/17

What we did today:

  1. Assigned work to each team member, following the agile development style, we now have 10 small, measurable tickets here – the goal of this sprint is to deliver 4 scenarios, and piloting graphical indicator for the next sprint. So we will have enough knowledge of the code in the team when the next sprint begins.

We have our first road blocker today – the WMDServer does not work on either of our environments, whether it being Mac, Windows 7 or Windows Vista, and we have decided to work on the following items:

  • Use the wiki here to put as much information as we could regarding the problem, and report it to Matthew before midday Jan 18, EST
  • Push the request for a publish server harder, so when the worst scenario happens, we can rotate the usage of the server to finish our work
TODO items:
  1. Input the information into wiki to remove the blocker asap
