6. Bottlenecks
Issues Identified
• High HEAP utilization on servers
• Even with frequent garbage collections, heap memory not being cleared.
• Too many SQL queries calls and multiple join statements
Impact
• Caused memory leak slowly, and after a few hours server fails to respond
• Transaction response time’s were large (~10secs for single users), scalability issues
Analysis
• Upon analyzing the heap dumps and JFRs (JRockit Flight Recorder) generated,
several large Objects can be identified.
