Some of our challenges

Complexity

Long-running end-to-end processes

Approx. 20 Human Tasks per process + automated service calls

Infrastructure with more than 750 Managed Servers in Production

300.000 calculated end-to-end process instances per year

Flexibility

Configurable through Business Rules, DVMs,

Process migration because of environment changes and new product releases are necessary

Top-down approach (contract-first)

Integration

Custom-defined user task forms that fit into existing implementations and future plans

Locking and Coordination

Manage database growth of MDS and SOAINFRA

Purging: Looping, Parallel, Partitioning

Oracle Fusion Middleware Administrator's Guide (chapter 9)

SOA 11G Database Growth Management Strategy

The character of the processes and the amount of instances is

important to find the right purging strategy (short-running or

long-running)

Setup the housekeeping

=> How should I design my SCA-Applications?

=> Which functionalities can be used twice or more?

=> How should I use features like partitions in order to

ease the monitoring of the composites during runtime?

Set the title-attribute of your composite instance with a

business related identifier

Use component-properties to change configuration

parameters of your implementations during runtime

Implement dynamic endpoint-binding pattern to avoid large if-

then-else trees (in BPEL: set property endpointURI during

runtime)

Create reusable components for BPM and ADF.

Decouple business data from process instance data.

Dont forget the housekeeping for BPM and ADF.

Create well defined interfaces that fit into your architecture.

Be prepared for the worst-case (Fault Management, Replay, Entry

Points, etc.).

Use MDS to share your metadata.

Define clear naming conventions in advance for BPM and ADF.
