Using best practices to accelerate application performance in mainframes

The organization, an energy utility client was facing real-time infrastructure issues owing to the lag in its front-end customer application during month-end activities. Severe challenges were faced in the customer care application that was based on mainframe. During month-end financial closing processes, the application faced heavy workloads. There were also problems related to excessive CPU utilization. Due to low CPU availability during critical periods, there were periodic crashes of business-critical applications residing on the mainframe and intermittent outages. Besides reducing overall performance, these infrastructure crises led to significant business disruption for the client.

To help the client handle excessive CPU utilization and business outages during month-end processing activities, Infosys team studied the client’s environment, conducted a careful analysis of the customer application, databases and mainframe, made recommendations to the application team based on their insights and leveraged proactive monitoring tools and automation scripts.

  • What best practices were used by Infosys?
  • How did the solution benefit the client?
  • What recommendations and benefits can you benefit from?

Find answers to these and a lot more in this detailed paper which was also shortlisted to be presented at Saint Louis Computer Measurement Group’s (STLCMG) 2017 conference.
