New features for LOB users
New Service Bus console

• Auto Purge: Automatically purge old data past
the retention point periodically on schedule.
AUTOMATED OPERATIONS.
• Modularity Profile: Reduce startup time and
memory by starting up only components used
(selected by selecting a profile). PERFORMANCE
• Lazy Loading: Reduce startup time by loading
composites only on first use. PERFORMANCE
IMPROVEMENT
• Exception centered management console:
Rework of the EM console to be centered around
exception conditions instead of business as usual.
RAPID PROBLEM IDENTIFICATION/RESOLUTION.
• Work Managers: Switch to work managers to
simplify and improve thread tuning. SIMPLIFIED
TUNING.
• Flow Trace: Switch to flow trace where multiple
composites are shown in a single trace for better
troubleshooting. SIMPLIFIED TROUBLESHOOTING.
New features for operations
Already in 12.1.3

• Availability
– Composite Instance Patching – patch long running instances immediately.
– Automatic Service Migration (ASM) – faster failover
• Performance
– In-Memory SOA – Optimized performance, scalability, reduced database growth.
– Integration Workload Statistics – Performance Diagnostic tool similar to DB AWR.
– Parallel Deployment – faster startup
• Resiliency
– Circuit Breaker – Improved resiliency
when downstream services go down.
10
New features for operations in 12.2.1
Oracle Integration Continuous Availability
A license to Oracle WebLogic Server Continuous Availability
is a prerequisite to license and use Oracle Integration Continuous
Availability. If using only In-Memory SOA, a license to Oracle
WebLogic Server Continuous Availability is not required.

11
Oracle WebLogic Server 12.2.1
Continuous Availability
• Automated cross-domain transaction recovery
Provides automatic recovery of XA transactions across an entire domain, or across an entire site
with servers running in a different domain or at a different site.
• Zero Downtime Patching
Provides an automated mechanism to orchestrate the rollout of patches while avoiding
downtime or loss of sessions.
• WebLogic Server Multitenant live resource group migration
Provides the ability to migrate partition resource groups that are running from one cluster/server
to another within a domain without impacting the application users.

12
Oracle WebLogic Server 12.2.1
Continuous Availability
• Coherence federated caching
Replicates cache data asynchronously across multiple geographically distributed clusters.
• Coherence GoldenGate HotCache
Detects and reflects database changes in cache in real time.
• Oracle Traffic Director
Routes HTTP, HTTPS, and TCP traffic to application servers and web servers on the network.
• Oracle Site Guard
Enables administrators to automate complete site switchover or failover.

13
Circuit breaker
Overview
• Automatically suspend upstream endpoints when a downstream endpoint is down
• Automatically resumes any suspended service when the downstream endpoint comes back up.
• Prevents fault buildup in the server. No need to bulk-recover faulted instances
• Supported for
– Web Service: Incoming requests are rejected for the duration that
the Web service is suspended.
– Adapters: JMS, AQ, DB, File and FTP adapters can be automatically
suspended in this release.
– EDN Subscribers: The EDN subscriber closest to the downstream
endpoint gets suspended.

17
Patch running instances
Why?
• A long-running BPEL contains a bug
• Certain long running instances have not reached this bug yet
• If you redeploy a new version, it will not fix running instances; only new ones
• If you deploy the same version, your instances will become stale
Patching a process will allow to fix running
instances and prevent the error from occurring!

18
What?
https://blogs.oracle.com/integration/entry/patching_soa_composite_instances_in
Compatible changes include
• Non-schema related XSLT changes
• Changes to fault policy, sensor data, and
analytics data
• Compatible BPEL changes such as sync/async
invoke, transformation activity, assign
operations, etc.
• JCA Adapter configuration properties
• Modifications of token values in composite
references
Incompatible changes include
• Deleting or renaming composite artifacts
• Updating binding properties
• Changes to a WSDL and Schema definition
• Changes to XQuery mappings
• Changes to BPEL receive inputs, structured
activities, assign mapper source/target/skip
conditions

19
How?
https://blogs.oracle.com/integration/entry/patching_soa_composite_instances_in
JDeveloper has a new role, the SOA Patch Developer
• Only allows compatible changes to be made
• patch.xml is created in project_directory/SOA/SCA-INF
to track changes

20
How?
Oracle made a typo here

21
How?
• Create a patch JAR with
– Jdeveloper
– sca_packagePatch
– ant-sca-package
• WLST sca_validatePatch and
sca_patchComposite can be used to
validate and apply a patch
sca_validatePatch('http://localhost:8001', 'weblogic',
'welcome1', 'sca_HelloWorldWsAddrCaller_patch.jar')

22
Automatic Service Migration (ASM) support
• Leverages WebLogic ASM feature
• Requires datasource
for leasing
• On failure migratable singleton
services are transferred to other
server (JTA, JMS)
• Failing back to original server
is not supported
https://docs.oracle.com/middleware/1221/core/CMEDG/GUID-079347E5-9DF0-44A9-9BF3-AF7C13D631B3.htm#CMEDG-GUID-6594C41E-ED8C-4E56-8578-B67250961831

23
Integration Workload Statistics
• Comparable reports to DB AWR
(Automatic Workload Repository)
• Helps with performance tuning
and tuning
• Takes periodic snapshots
saves them to database
• Allows generation of reports
(XSLT, CSV, HTML)
https://docs.oracle.com/middleware/1221/soasuite/administer/GUID-266118F3-8B14-4896-8081-A0A489FD0CEC.htm

24
• IWS reports metrics
– System resource usage
– Composite statistics
– Statistics for internal system queues
– Statistics for synchronous and asynchronous business
processes
– Endpoint statistics
• The components supported
– BPEL Service Engine
– EDN (Event Delivery Network)
– Web Service Binding
– File Adapter
– JMS Adapter
– FTP Adapter
– DB Adapter
– AQ Adapter
– MQ adapter.
• Not yet supported
– REST binding

27
Example process to measure
• Simple Hello World process
– Using REST Binding or SOAP
– Using untyped JSON or XML
message (in BPEL)
– Containing an XPATH assign
or a JavaScript assign

28
Endpoints and wires
HelloWorldXML and HelloWorldXMLJS are SOAP services
HelloWorldJS and HelloWorldJSXML are JSON services

29
Activities and processes
HelloWorldXML and HelloWorldXMLJS are SOAP services
HelloWorldJS and HelloWorldJSXML are JSON services

30
SOAPUI Results
Different results! Here pure JS is fastest!

32
In-memory SOA. Why?
• Improves performance and scalability (especially if SOAINFRA DB is the bottleneck)
• Reduces SOAINFRA database growth
• Less purging required

33
In-memory SOA. How?
• Leverage Coherence cache to run your non-transactional (non-XA) business processes in memory
• Only for short-running processes
• Set at component level
• Persistence settings:
– Immediate. Same as In-memory not enabled
– Deferred. Audit data eventually ends up in
database
– Fault. Audit data only ends up in database in
case of a fault

34
In-memory SOA
Transactions are not supported
• Do you need transactions when you
can use compensation handlers?
• Transactions spanning multiple services
are difficult anyway
• timeout settings on different levels
• XA datasources
• WS-AT headers and coördination,
node trust settings, etc

35
In-memory SOA

http://www.oracle.com/technetwork/middleware/soasuite/overview/wp-soa-suite-whats-new-12c-2217186.pdf

38
New in 12.2.1
• JavaScript in SOA composites
• JavaScript in Service Bus
• REST support (native, end-to-end)
• Debugger enhancements

39
JavaScript support in SOA Suite
The JavaScript engine
• Rhino is an open-source implementation of JavaScript written entirely in Java
• Mozilla Rhino v1.7R3
– is included in JDK7
– can be used with JDK8 (SOA Suite 12.2.1) (e.g. http://andreas.haufler.info/2015/04/using-rhino-with-java-8.html)
– ECMAScript 5 support
– Partial JavaScript 1.8 support
• ECMAScript 5 vs JavaScript 1.8
– JavaScript 1.8 is Mozilla's implementation of ECMAScript 5 with added features
– a superset of the ECMAScript specification
• Rhino 1.6 and greater supports ECMA-357 ECMAScript for XML (E4X)
– Can be used server-side in SOA Suite 12.2.1
– Native XML in JavaScript

40
Why Rhino and not Nashorn
• "ECMAScript 5.1 language specification doesn't define multithreading semantics for programs
written in the language; they are inherently single threaded. If we were to make them thread safe,
we'd be sacrificing single threaded performance for a behaviour that falls outside of the
specification.“
• Nashorn library internals themselves are thread safe, but JavaScript programs executing within a
single engine instance are not thread safe. This is different from Rhino. Using Nashorn, you
probably need to take steps to protect your ScriptEngine from concurrent access, which might
explain the unpredictable behavior you observe.
https://blogs.oracle.com/nashorn/entry/nashorn_multi_threading_and_mt

41
E4X
• var languages = new XML(
'<languages type="dynamic">
<lang>JavaScript</lang>
<lang>Python</lang>
</languages>‘
);
• var c = languages.lang.length()
• languages.lang += <lang>Ruby</lang>;
• var a = 2;
var b = <foo bar={a}>"hi"</foo>;
• var languages =
<languages type="dynamic">
<lang>JavaScript</lang>
<lang>Python</lang>
</languages>;

42
