SAP/Wily Relationship From 2004 Until Now > SAP Active Global licensed Introscope from Wily in 2004 so that AGS engineers could diagnose Java performance problems for all their NetWeaver customers. > May be fully licensed and resold to SAP customers by SAP sales > More than 800 SAP customers have deployed SED
Click for Solution Architecture
Summary of Challenges our SAP Customers Face > As more SAP customers deploy SAP applications on NetWeaver, more of their end-s are affected by NetWeaver problems that can occur. > In the past, SAP s lacked visibility inside their NetWeaver Java servers and would just bounce servers to deal with problems. That is inadequate. > SAP s did not have tools to monitor the health of their NetWeaver Java servers. > They were unable to determine the root causes of Java performance issues; they could not even tell if the problem was in the Java server or in some back-end system.
Click for Solution Architecture
Wily for SAP NetWeaver Capabilities > Real-time visibility into application performance so you can quickly resolve problems > Monitoring of applications in production without impacting performance > Proactive alerting which can notify your organization about problems before most s are affected > Persistence of historical data for better capacity planning and trend analysis > End experience monitoring > Correlation with ABAP metrics Click for Solution Architecture

> Authentication Keeps Getting Slower and Slower
Are connections to your SiteMinder server running out?
Is there a memory leak?
Is U utilization climbing?
> One Particular Database Query Takes 20 seconds
Was an index on the table dropped?
> An XI Queue gets Stuck
Are Errors occuring that stop the processing of messages?

Application Death Caused by Memory Leak in Java Code Java Memory Management: The Garbage Collector
