PI performance check document

[mike_sibler]

Motivation:

The PI performance check is one of the central SAP documents for the tuning of the PI / PO system. The last version of this document was released more than two years ago. In the meantime with the PI releases 7.31 / 7.4 and 7.5 many new features were introduced that also have an impact on the performance of message processing. Therefore it was time to update the guide. Apart from adapting the layout to the general SCN template format, many chapters were reworked and many new topics were added. This topics span the whole PI scope - from the Advanced Adapter Engine, the ABAP Integration Engine and also the impact and eventual changes on the IDoc and Proxy SAP backend systems.

New topics added in the new version:

• Long processing time for Lean Message Search

• IDoc posting configuration on receiver side

• Tuning of SOAP sender adapter

• More information about IDOC_AAE adapter tuning

• Packaging for Java IDoc and Java Proxy adapter (PI 7.31 and higher)

• New Adapter Framework Scheduler for polling adapters

• New performance monitor for Adapter Engine (PI 7.31 and higher)

• Enhancements of the maxReceiver parameter for individual interfaces (PI 7.31 SP11 and higher)

• Include latest information for staging and logging
  (restructured to be part of Java only chapter) (PI 7.3 and higher)

• FCA Thread tuning for incoming HTTP requests (PI 7.1 and higher)

• Enhancements in the Proxy framework on sender/receiver ERPs

• Large message queues on PI Adapter Engine (PI 7.31 and higher)

• Generic J2EE database monitoring in NWA

• Appendix section: XPI_Inspector

Where can I find the guide?
The guide can be downloaded via SAP Note 894509.

Is this guide only relevant for dual-stack PI?
The Performance guide discusses all the components of a PI installation - meaning the ABAP Integration Server as well as the Advanced Adapter Engine (AAE). The tuning options described for the AAE are also relevant for the Java Only PI (Advanced Adapter Engine Extended (AEX)) and the PI part of a Process Orchestration (PO) system. The aspects of NetWeaver BPM in a PO system are not covered in the guide yet . This is planned for the next version (see below).

Is this document also relevant for PI/PO 7.5?
In general the document aims at all releases higher 7.1. Of course many of the key capabilities of the AAE are only contained in later releases and these topics are then not relevant for older releases. But in general the document always mentions the corresponding release that is necessary to use the described feature. The guide can also be used generally for 7.0x systems. Older versions of the guide are still available in the Service Marketplace as described in SAP Note 894509.
