SAP PI brings the final divorce between


2

• Federated PI



Federated PI landscape

• Central

• Distributed

• Federated



2

• AEX



Single Stack capabilities via AAE

Advanced Adapter Engine Extended



AEX 1

• Single Stack

– reduced TCO Fast installation Less hardware fast restart

• Speed up to 10 times faster

• 1 monitoring• 1 monitoring

• Support for HTTP and IDOC

• Interface and mapping split

• User defined message search

• Enhanced integration with SM



AEX 2

• Integrated scenario from PIS

• XML validation redesign (ESR schema based)

• Large binary to binary file transfer

• Time-out config per comm channel• Time-out config per comm channel

• Pub and sub for JMS Topics

• Stand alone or in combination with PI

• Using AEX as manual fail over system

• Eclipse based tools



2

• PI 7.3 Java only



PI 7.3 Value proposition



ES Repository 7.3 (CE7.3 and PI7.3)



Service bus

SAP NetWeaver PI 7.3



2

• Performance boosts



Performance 1

• Message blacklisting

– Identifies possible disruptive messages

• Flag them as suspicious upon server restart

• Cancel upon second restart



• Cancel upon second restart

– Avoid multiple server restarts

– Status DLNG will be blacklisted and all messages

which is already listed will be NDLV

– Search in monitoring

– Restart by administrator

2

• JVM improvements



JVM improvements 1

• Advanced garbage collection and improved

JVM instability detection:



JVM improvements 2

• Process unlimited file sizes

• Deliver constant response times for sync mess.

• Avoid inconsistent messaging status or

restarts due to unhandled JVM exceptions



restarts due to unhandled JVM exceptions

• 16 GB JVM nodes (big files)

• Background GB runs constantly for good

response and stability

2

• Simplified configuration



Simplified Configuration 1



Simplified Configuration 2



2

• CPA cache



Reworked CPA

• Reworked cache refresh leads to:

– More robust and faster processing

• Optimized object loading during full cache

refresh using temporary files, cache queries in



refresh using temporary files, cache queries in

memory

• Changed CPA cache refresh update on adapter

engine leads to less memory consumption and

less communication over server nodes

• Speeds up pipeline processing, less read!!

2

• XI 3.1 protocol



XI 3.1 protocol

• For communication between PI components

– Integration Server <-> Adapter Engine

– Integration Server <-> Integration Server

• Leads to performance improvements,



• Leads to performance improvements,

especially on Adapter Engine

• Easier and faster EO message processing

between PI components

• Works out of the box

2

• Queue handling



Error’s and Queue’s

• EO messages assigned to a queue block when

in error

– Now, error message is moved to another queue

– Relieves administrator monitoring queues



– Relieves administrator monitoring queues

– Prevent inconsistent qRFC status for unhandeld

exceptions

– Long awaited functionality

– Rebalancing queue’s

2

• Adapter specific news



Adapter

• PI 7.3 allows to control the resources usage

per adapter channel

– Some adapter allow control for maximum parallel

connections



connections

• No channel can clog up the adapter

• Business critical interfaces always get resources

Things to ponder

• PI 7.3 java only does not mention what to do

with BPM… and they are o so present!!!

• Integration with CE? What’s the future for PI?

• SAML…. IM helps a little bit, but then again…



• SAML…. IM helps a little bit, but then again…

• Java only monitoring under construction…

even michal krawczyk had some issues during

Teched hand on experience

• Performance of PI really is better!
