I wanted to provide an update on our system upgrades after last week's issues. The first phase of our upgrade program was completed successfully last Thursday, and our preliminary analysis is showing a significant improvement to system performance (roughly 50% faster page response times at peak periods), along with the restoration of stability (no incidents reported despite continuation of record load). While there is still work to be done, these results are very encouraging and customers are reporting a significant improvement in system performance.
Last week's upgrades included adding additional servers to the application tier to provide more capacity, making changes to session management to improve performance, software changes to improve data access and retrieval, and segregating application servers to further isolate specific software components.
Phase 2 is scheduled to be completed during an extended maintenance window this weekend, involving additional capacity expansion, upgrades to our load balancing infrastructure, additional software changes to further optimize processing, and extensive database maintenance to improve query performance.
Phase 3 is planned for later in March, in which we will complete the migration of our Oracle database from the current Windows-based environment to a new 64-bit linux platform, on improved hardware.
As mentioned in my previous post, we had planned these upgrades to take place over the course of the full year, but given the issues that surfaced last week, we made the decision to reprioritize and get firmly ahead of things by deploying the planned upgrades on an accelerated schedule.
I'll keep you posted as the additional upgrades progress.

I just want to say, what a great idea to have the CEO blog on the progress the company is making. It definitely gives the customers and potential customers a personal insight to the company from the CEO's perspective. I one use to work with a reseller of this product and very much enjoyed managing the relationship between Andera and our customer. It was a great product.
How are you handling the increased risk in this accelerated upgrade strategy? On the outside it looks like you are taking a year of work and squishing into 3 months.
