3 About Me Ahmed Aboulnaga 15+ years of Oracle middleware experience Focus on Oracle Fusion Middleware, with emphasis on SOA, identity management, and portal technologies Oracle ACE, OCE, OCA Author / Presenter / Blogger President of WMOUG / EGOUG Raastech, Inc All rights reserved. Slide 3 of 52

4 What is this presentation about? For the experienced Oracle SOA technologist Random tips and tricks surrounding the following product sets: SOA Suite 11g BAM 11g OSB 11g OWSM 11g OSR 11g Goal is to share things you may never have heard about or come across Raastech, Inc All rights reserved. Slide 4 of 52

8 Understand what BAM is designed for Not a data repository use OBIEE instead Not intended for large amounts of data (think millions of records per data object) Our mistake: Instead of composite sensors, dumped huge amount of sensor data into BAM Why is this a problem? BAM unable to handle extremely large loads effectively BAM reports are exceptionally weak Who nowadays develops web apps that run only in IE? Best used for aggregated data that needs to be reported against in near real-time Raastech, Inc All rights reserved. Slide 8 of 52

Weak BAM reporting capabilities No user sorting No field expansion Cumbersome

BAM runs only on IE Yes, I know the history of BAM but still

11 Don t forget about BAM purging People tend to forget about purging BAM Data Objects If data object is based on a database table: Simply create a scheduled PL/SQL package to purge the data Otherwise: Use BAM Alerts Raastech, Inc All rights reserved. Slide 11 of 52

13 Avoid BAM RMI Adapter BAM Adapter comes in 2 flavors; RMI and SOAP In your code: eis/bam/rmi eis/bam/soap Avoid RMI because: It is not as efficient as SOAP Bug in BAM Adapter leads to BPEL threads not being released Raastech, Inc All rights reserved. Slide 13 of 52

Understanding BAM inbatch= Y The BAM Adapter property inbatch batches requests into batches

15 Understanding BAM inbatch= Y BAM Adapter reports success 100% of the time, but pushes the data as predetermined intervals Works great, but if there is an error in a single BAM record: The entire batch fails Unknown which record failed Failure not always in SOA logs but sometimes in BAM logs Raastech, Inc All rights reserved. Slide 15 of 52

16 Understanding BAM inbatch= Y SOA Suite UP SOA Suite Goes DOWN BAM UP Requests are batched in SOA Invocations always success Batched requests are lost BAM Goes DOWN Requests are batched in SOA Invocations always success Limit to how much can be batched Both are down idiot! Raastech, Inc All rights reserved. Slide 16 of 52

18 OSB Summary Pros Stateless, so performance is superior Caching, throttling, service virtualization Can search indexes in payloads (if enabled) Cons Cannot reference MDS Shared custom code required for DVM support But cannot support multi-input DVMs Severe limitations in transactional visibility, tracing, and metrics WSDLs/XSDs must be copied locally Raastech, Inc All rights reserved. Slide 18 of 52

19 OSB vs. BPEL Performance OSB Med OSB OSB Med Service BPEL Med Med BPEL Med Service 1000 transactions (OSB) = 3:32 minutes 1000 transactions (BPEL) = 10:19 minutes OSB is superior in performance to BPEL (68% better) Raastech, Inc All rights reserved. Slide 19 of 52

21 OSB Report Action OSB performs 2x to 4x faster than BPEL (great!) OSB sucks in terms of transactional visibility Consider using the Report Action to capture SOAP headers and SOAP bodies Consider creating a web service to log key metadata (e.g., think BPEL sensors) Raastech, Inc All rights reserved. Slide 21 of 52

request/response is 4x slower This is the only OSB

22 OSB Report Action Can filter by index Header and body are displayed separately Enabling header/body on both request/response is 4x slower This is the only OSB functionality that is persisted Raastech, Inc All rights reserved. Slide 22 of 52

23 OSB Report Action For all Proxy Services, in the request stage: 1. Add a Report action for $header 2. Add a Report action for $body 3. Specify at least one Key Name for both 4. Add the Request string to the name and use the same value from the body Raastech, Inc All rights reserved. Slide 23 of 52

24 Using JCA Adapters in OSB OSB provides native adapters JCA Adapters must be created in JDeveloper 11g.JCA and.wsdl manually imported to OSB project Not supported for all adapters (DB Adapter yes, FTP Adapter no) Raastech, Inc All rights reserved. Slide 24 of 52

OSB Caching Result Caching (Coherence) on Business Service To be used with data that is not frequently updated (e.g., product info) Will not re-query backend until it has expired 15% to 25% performance improvement with DB Adapter Raastech, Inc.

25 OSB Caching Result Caching (Coherence) on Business Service To be used with data that is not frequently updated (e.g., product info) Will not re-query backend until it has expired 15% to 25% performance improvement with DB Adapter Raastech, Inc All rights reserved. Slide 25 of 52

26 OSB on Exalogic Problems On OSB installations on Exalogic, the following problems were experienced: Client requests get a read time out error The BEA error Request Entity Too Large appears in the logs OSB invocations retry multiple times every 5 minutes OSB invocations invoke target service twice Raastech, Inc All rights reserved. Slide 26 of 52

27 OSB on Exalogic Solution For all Business Services 1. Under HTTP Transport Configuration 2. Set Use Chunked Streaming Mode to Disabled For all Proxy Services 1. View Message Flow 2. Edit Route Node(s) 3. Check on Quality of Service and set it to Exactly Once Raastech, Inc All rights reserved. Slide 27 of 52

28 OSB Access to AIA Foundation Pack XPath Functions 1. Copy the AIA JAR from the SOA home to the OSB server: cp $MW_HOME/aia5/lib/aia.jar $MW_HOME/Oracle_OSB1/config/xpath-functions Raastech, Inc All rights reserved. Slide 28 of 52

29 Securing OSB Services with OWSM 1. Click on the Proxy Service 2. Click on the Policies tab 3. Select From OWSM Policy Store and click Add 4. Select the policy oracle/wss_username_token_service_policy 5. Update, activate, and submit the changes Raastech, Inc All rights reserved. Slide 29 of 52

30 Securing OSB services with OWSM 6. When testing, add the following SOAP header to the envelope: <soap:header xmlns:soap=" <wsse:security soap:mustunderstand="1" xmlns:wsse=" docs.oasis-open.org/wss/2004/01/oasis wss-wssecurity-secext-1.0.xsd"> <wsse:usernametoken wsu:id="usernametoken-tk6qmwkq5hl3md2invp16q22" xmlns:wsu=" <wsse:username>oratest</wsse:username> <wsse:password Type=" </wsse:usernametoken> </wsse:security> </soap:header> Raastech, Inc All rights reserved. Slide 30 of 52

32 Securing SOA services with OWSM 1. Navigate to the composite, scroll down, and click on the reference 2. Click on the Policies tab 3. Attach the policy oracle/wss_username_token_service_policy Raastech, Inc All rights reserved. Slide 32 of 52

33 Optimized calls if using ServiceURL Ensure that URLs used for composite-to-composite invocations are identical to the setting in ServerURL SOA Suite optimizes these calls (uses RMI internally) Raastech, Inc All rights reserved. Slide 33 of 52

34 Avoid Mediator Parallel Routing Rules See this presentation for details why: Raastech_2013_Collaborate_SOASuite11gPerformance.pdf Edit all *.mplan files for your asynchronous Mediator operations and change the executiontype as follows: OLD: executiontype="direct" NEW: executiontype="queued" Raastech, Inc All rights reserved. Slide 34 of 52

achieves the same thing No need to maintain a queue; BPEL recovery tables

35 Consider 1-way BPEL Instead of Queues Queues are great ways to force asynchronicity of your integration But using 1-way BPEL async invocations achieves the same thing No need to maintain a queue; BPEL recovery tables are used internally BPEL BPEL Raastech, Inc All rights reserved. Slide 35 of 52

36 Use MDS for all WSDLs Consider ORAMDS instead of HTTP for composite-tocomposite invocations Removes the composite loading dependency (It s still translated to an optimized call behind the scenes) <reference name="asyncstatus" ui:wsdllocation="oramds:/apps/wsdls/asyncstatus.wsdl"> <interface.wsdl interface=" <binding.ws location="oramds:/apps/wsdls/asyncstatus.wsdl" port=" soapversion="1.1 /> </reference> Raastech, Inc All rights reserved. Slide 36 of 52

38 Singleton property with JMS Topics For inbound JMS Adapter from a topic, use the singleton property to avoid consumption of multiple messages in a cluster <service name="jmsconsume" ui:wsdllocation="jmsconsume.wsdl"> <interface.wsdl interface=" <binding.jca config="jmsconsume_jms.jca"> <property name="singleton">true</property> </binding.jca> </service> For more information: Single message consumption from distributed topic in WebLogic Server 11g Understanding the "singleton" property with WebLogic JMS topics Raastech, Inc All rights reserved. Slide 38 of 52

39 Avoid Distributed Topics Not possible to have truly highly available JMS destinations Expectation: Reality: 1. With 1 consumer, if code is deployed to all 4 nodes of the cluster, the message is consumed only once 2. Message is equally available to all nodes of the cluster, so if any node fails, the message is still available and can be consumed without manual intervention Point #1 is not possible if you set the forwarding policy to Replicated Point #2 is not possible if the destination's forwarding policy is set to Partitioned Since these are the only two options available, unable to satisfy both requirements See Raastech, Inc All rights reserved. Slide 39 of 52

41 Direct Binding in OSB? Yes or No? 1. Edit the business service 2. For Protocol, select soa-direct 3. For Load Balancing Algorithm, select round-robin 4. For Endpoint URI, use the format shown in the screenshot Raastech, Inc All rights reserved. Slide 41 of 52

42 Direct Binding in SOA? Yes or No? 1. Edit the proxy service 2. Under Transport Configuration, modify Protocol to sb 3. In the OSB proxy service, Export WSDL via the icon and save it to your local file system 4. Extract the contents of the JAR file to your local file system 5. Create a Direct Binding reference Enter a name Ensure that Type is a Reference Ensure that Reference Target is Oracle Service Bus Manually import the WSDL and all referenced WSDLs/XSDs into the project The Reference Binding Details will be automatically populated Raastech, Inc All rights reserved. Slide 42 of 52

45 PassThroughHeader Property Do you need to use the passthroughheader property? Allows elements in the header to pass from one composite to another Otherwise, elements in the header that are not explicitly referenced will be dropped before they are passed to the next composite. <component name="updatecustomer"> <implementation.mediator src="updatecustomer.mplan"/> <property name="passthroughheader">true</property> </component> Raastech, Inc All rights reserved. Slide 45 of 52

47 Why consider a service registry? Over time, most organizations encounter the following problems: No central service registry Creation of duplicate/redundant services Difficult to obtain interface specifics on existing services Raastech, Inc All rights reserved. Slide 47 of 52

51 Summary BAM: Use it for what it is intended for OSB: Superior performance, poor visibility SOA Suite: A lot of things to consider; learning about all aspects of the products takes time and experience WebLogic Server: Avoid JMS topics Integration: Avoid direct binding OSR: Avoid altogether Raastech, Inc All rights reserved.
