10. Performance and Scalability HP is highly dependent on the Performance of the Application given our requirements and usability across the globe. Our Application is considered as Mission critical and high availability is a basic requirement. We have come across major performance issues and also stabilized them in the shortest of the time. Our performance concerns –  Stuck Orders and Requisitions  User Folder Items  User navigation between Screens  System hangs - Progress bar hangs  Supplier Bidding  Master Data loads and CDS pulls  Workflow issues  Database locks  Reports timeout © 2012 Ariba, Inc.

11. Performance and Scalability Solution for Performance issues Increased Task Runner Nodes Database tuning Optimization of Queries Changed Search logic Memory Tuning Rolling Restart of Nodes and Weekly Full Restart Indexes and db stats Controlled User Permissions Reduced Folder Items Performance testing is performed on each release using loadRunner and WinRunner Any performance issues that occur between releases are addressed with tuning. © 2012 Ariba, Inc.

12. Performance and Scalability 12 © 2012 Ariba, Inc. All rights reserved. Scalability is a very important aspect to maintain the consistent performance of the application. Our automated monitors track the application metrics to avoid system downtime and sends alerts to support team. We have exponential growth in users and transactions over years. In order to provide a good performance, we have increased our server’s capacity and increased the nodes. HP has high standards for Technology and Hardware and to keep up to the pace of these standards we have to keep moving to latest Hardware and technology which has helped us to monitor the scalability factor frequently.
