1827219 - Minimum number of J2EE Server Nodes for Productive SAP Process Integration (PI) Systems

Symptom

You are currently running an SAP Process Integration (PI) system, in your production landscape, with a single Java server node per Application Server. Because of this single Java node configuration, your PI system is currently experiencing performance bottlenecks and/or system instabilities.

Performance bottlenecks usually occur in the form of:

  • Long processing time of PI messages;
  • Message backlog;
  • Communication channel time-outs; and
  • Serial processing of requests for specific adapters like File and JDBC. 

Instabilities are typically in the form of:

  • OutOfMemory (OOM) exceptions due to overload (e.g., high number of parallel mappings),
  • Long Garbage Collection pauses causing application processing to stop, and
  • Insufficient capacity to handle failover scenarios since the Java server node is a single point of failure.
