Most of you are aware that Unify experienced some major performance issues as
we tried to close out the month of July. Not to go into any details but there seemed to be a lot of smaller issues which when combined caused the issues we saw on Monday and to a lesser degree on Tuesday. Almost all of the issues relate to the quirkiness of the current version of Sybase which is used for Unify's database. Jeff Johnson and his team are putting together a plan that will address most of these issues and hopefully result in acceptable performance as we go through next bidweek and try to close for August. The short term tactical plans include the following: Enhancing certain programs which seem to have become resource hogs as the amount of data grows. Test and hopefully migrate to the latest version of Sybase which will address some of the issues. This may also require some hardware changes as to where we store certain data. We will also need some user help in stress testing prior to moving to production. Addressing with the users billing transactions that have never been finaled. I have been told that we still have transactions going back to Jan of 99 that have not been finaled or closed out. This puts quite a load on the PMA and accrual process since it has to go back to those open transactions to see what if any action should be taken with these transactions. Once these changes have been implemented and hopefully bought us a little time to absorb the tremendous growth we've been seeing via EOL then we will focus on delivering more intermediate and longer term solutions. These include the following: Rewriting most of the code and moving to a 3 tier environment which will be much more scalable. Moving off of Sybase and on to Microsoft SQL Server or Oracle. It will be easier to move Microsoft SQL Server but we have to be sure it is the right solution in the long term. Jeff will be following up with some of you to go over a much more detailed plan. Needless to say that this is his groups highest priority and his best people are working on these efforts. This will slow down major enhancement efforts such as enhancing the gas applications to handle hourly trades and nominations. We will keep you informed as we start to roll out the tactical solutions. In the mean time feel free to contact me at x-36858 or Jeff at x-39694 if you have any questions or require additional detail. Thanks! - Tommy
