ABOUT XEROX

Xerox

•  Founded 1906 •  140,000+ employees •  Active in 190+ countries •  2014 Revenue: $19.5 billion •  For more than a half a century, Xerox has been a leader in document

technology and services


Xerox Healthcare solutions


Xerox Health Enterprise Framework


MEDICAID MANAGEMENT INFORMATION SYSTEM (MMIS)

Solution

•  Preferred Medicaid Management Information Systems provider

•  End-to-end healthcare program administration services and solutions

•  Automated solution for complex data intensive deeply regulated market

•  Interfaces with existing systems •  Input from web, phone, batch jobs, programmatic


Features

•  Service Oriented Architecture platform fully aligns with MITA interoperability guidelines and web-based technologies

•  Reusable, adaptable core provides common starting point –  Reduces implementation time & costs

•  Fully aligned with the MITA 3.0, MECT & the Seven Conditions and Standards from the first day of service

•  Flexible architecture enables edits and updates to be implemented in days or hours – not weeks or months

•  More than 40 years experience with Medicaid and other publicly funded health programs


Use Cases

•  Providers enter claims and other information •  End users can check health care coverage and claims •  State employees can approve / deny / administer •  Third Party Integration •  Batch processing


ARCHITECTURE

Modularity


Presentation Layer


•  Processes the presentation and information dissemination for users

•  Web Portal provides the information via a web browser.

•  AVRS allows providers and members access to information by using a touch-tone telephone.

•  EDI provides connectivity for the flow of data between providers, state agencies & switch vendors

Business Process Layer


•  Encapsulates high-level business processes exposed as service for consumers

•  Uses well-defined execution of services and components

Services Layer


•  Composite services –  Combines granular business

services to reduce some complexities and to reduce coding efforts.

•  Business Service Layer –  Provides specific business

services which are highly cohesive and atomic functionality

•  Infrastructure Service Layer –  Supports systems integration

services that are necessary to build a web application

PERFORMANCE OPTIMIZATION

Goals

•  Throughput •  Response time for different use cases •  Batch processing throughput and response time


Implementation

•  Agile process •  Rational Performance Tester for recording & playback •  Analysis of performance issues and bottlenecks with AppDynamics software •  Tuning and code adjustment •  Repeat


Major Improvement Items

•  Heap size tuning •  Connection pool tuning •  CPU and RAM assignments •  Virtualization changes •  Portal 8.0 -> 8.5 •  WSRP updates as part of Portal upgrade •  Theme optimization •  WCM caching


Major Improvement Items

•  WSRP logout (now part of Portal 8.5 CF6) •  Database indexing / adding of new indexes •  Thread Pool Tuning

–  LDAP –  WebSeal –  ORB –  WSRP

•  Increasing number of JVMs where needed for memory reasons


Custom Code Adjustments

•  Reduction of redundant calls •  Optimizing SQL statements •  Co-locating BPM and Business Layer •  Making calls asynchronous •  Reduction of logging •  Fixes in WAS, WSRP, JSF, Hibernate, Log4j


APPDYNAMICS

Application Performance Management

•  Auto-discover and monitor end-to-end application performance •  Monitor any production app within minutes •  Monitor production apps at code-level depth with minimal overhead •  Resolve application issues quickly for exceptional end-user experience •  Eliminate false alarms with automated baselining •  Broadest coverage of languages and technologies •  Deploy On-premises, in the cloud, or in hybrid environments


Why use at Xerox?

•  Easy to setup •  Allows code level analysis without large overhead / complicated

instrumentation •  Follows transactions through a complicated set of transactions on various

layers – even using different technologies •  History based data can be analyzed later – very helpful in multi-shore

development •  Agile


Why use at Xerox?

•  Production Monitoring and Alerting with very low overhead •  Flexible views and dashboards •  Dynamic detection of different transactions – via URL patterns •  Browser based •  Delegated Administration


Adjustments

•  Learning of URL patterns •  Database extensions / detail levels for slow SQLs •  Need to monitor physical CPUs vs. virtual •  Did not catch vmotion performance issues •  PMI data is available
