General Questions


Where is your business logic ?

What if you need to change it?

How many systems require changes if one system changes?

Do Web Services help?

-> tight coupling �

5

Enterprise Application Integration(EAI)EAI tries to solve the integration problem

Examples of EAI System are:

• BEA Weblogic Integration (=WLI, discontinued)• TIBCO Business Works• Vitria•WebMethods


EAI Characteristics

• Addresses the integration problem-> Supports plenty of technical protocols• You need to DEPLOY the solution (EAR / JVM)• Does NOT support real business processes -> Technical level, NOT business level-> No long running processes (e.g. 10 years?)-> Not good in versioning


6

EAI reduces complexity from O(n*n) to O(n): One change per system changed.

Business Process Management(BPM)BPM deals with business workflowsIdeally: what you design is executable -> Visio templates do not qualify as BPM

Examples of BPM Software:• Oracle BPM = Aqualogic BPM = Fuego• TIBCO IProcess & TIBCO InConcert


7

BPM Characteristics

• Business architect draws executable workflow that makes sense for business -> business logic

• Human interaction

• Long running processes(e.g. 2 yearly vehicle inspection stickers, TÜV)

• Versioning of running processes


Service Bus

• Similar to EAI (same protocols) butconfiguration driven

• Service Bus is stateless• Often replaces EAI: Weblogic Integration (=EAI) is obsolete now• You design message flows on a technical level


8

Service Bus

-> Service Virtualization Layer


Drag and Drop Programming

BPM, EAI and ESB: They all have executable, graphical flow diagrams.


9

Why OSB is not BPM nor EAI

… not a BPM system: -> neither long running nor stateful nor versioning

… more then an EAI system: -> configuration driven, registry / repository integration, SOA focused and better monitoring with SLAs.

OSB typically does NOT host the services

Oracle Service BusOSB 10gR3

• OSB was BEA Aqualogic Service Bus (ALSB)

• ALSB based on code from Weblogic Integration (EAI)

• Key product of the BEA acquisition

• Integrates with UDDI V3 registry e.g.Oracle Enterprise Registry

Service Bus Functionality Overview I

• Loose coupling

• Location Transparency

• Dynamic Routing

• Schema Transformation

• Protocol mix and match


Service Bus Functionality Overview II

• Service Aggregation

• Load balancing, Clustering for Availability

• Security

• Monitoring

• Configuration driven

Routing


Log Action

Logs Xquery expression with annotation text and severity level to stdout.OSB console:


15

Dynamic Routing

Routing based on runtime conditions:

• Outcome of call to another service

• Logical expression

• Content of message body

• Content of transport header


Schema Transformation

• XSD schema -> XSD schema • binary (MFL) -> XSD schema • XQuery or XSLT

Example:Transform SAP address format to company-wide address format.


16

Eclipse: XQuery Mapper

Import Xquery from Eclipse as OSB resourceSlide #36(c) 2009/2010 Dr. Frank Munz / munz & more (Event:DOAG Nürnberg 11/2010)

Xquery Join

SLA Conditions

Depend on type count vs. min/max/avg

Conditions can be combined


Reporting Console

Search for reports via key

Purge all reports or range asynchronously

SECURITYSECURITYSECURITYSECURITYinbound, outbound, authorized & single signed on

2 Scenarios...

Web Services Security Pass-Through:• Proxy ignores WS-Security header, payload encrypted• OSB forwards message to service implementation

Active intermediary:• Security header examined• Encrypted messages get decrypted at proxy service

Throttle

Limit number of concurrent messages to business service.Exceeding messages put in non-pers. queue.

Queue full or expiration drops messages witherror message
