BPEL 10.1.3.3 Optimizes Assigns

One thing that "noobs" to 10.1.3.3 (including me) is surprised by is that 10.1.3.3 optimizes assigns and transforms. Ie assigns that are in the same scope and directly after each other is coalesced to one since assign.

For instance the following BPEL scope in Jdeveloper:

Is suddenly a single assign in the BPEL console:

It looks to me that the assign activity is named by the first assign in the series, so you should give a good name to that first assign, and remember assign - transform - assign will show up as just a single assign.

JDeveloper BPEL Assigns messes with your head ?

Have you ever wondered why the BPEL Assigns are "inline" by default? :

Is it because you should not be able to see the contents of the assign without going to the source code?

As we all know the default can be changed to regular dialogs by changing the "Use inline editors" in the "Diagram Properties" dialog:

Still however the dialog does not remember how you resized it the last time so it always pops up in its default size:When I really wanted:

This is really annoying and time consuming, even one of my first hacks saved the state of the window when the application was closed down.

ZMover to the rescue

Since I think this behaviour is really annoying I use ZMover (thanks to Michael M @ Kentor for the tip) to rearange any "Edit Assign" that pops up. So I suggest that you try it out too if you are frustrated with the "Edit Assigns". Sadly it cannot rearrange the spacing of the columns, so that is left as homework (each time you open a large assign).

SOA Suite 10.1.3.3 - Remote fault policies

Prior to SOA Suite 10.1.3.3 one could specify the partnerlink properties retryMaxCount and retryInterval for retrying remote partner link faults within the bpel.xml file:

<partnerLinkBinding name="mypartnerlink">
<property name="wsdlLocation">theWSDL.wsdl</property>
<property name="retryMaxCount">4</property>
<property name="retryInterval">60</property>
</partnerLinkBinding>

In 10.1.3.3 Oracle decided to add a "aspect oriented" fault managment policy framework to ease fault management and to keep it in a central location.

In 10.1.3.3, the the partnerlink properties retryMaxCount and retryInterval are thenfore ignored and the new fault management policies needs to be used instead of the old setup.

The fault managment setup consists of the following files:

• %ORACLE_HOME%\bpel\domains\\config\fault-bindings.xml
• %ORACLE_HOME%\bpel\domains\\config\fault-policies\*.xml

Note: If you create a new domain you will need to create the files manually since they are not created by default.

Here "fault-bindings" refers to policies defined in the "fault-polices" folder. That is the fault-bindings file defines which policies that are to be appliced to which processes/partnerlinks.

The XML Schema definitions for the fault policy settings are avaliable in the XMLLIB location:

• %ORACLE_HOME%\bpel\system\xmllib\fault-policy-binding.xsd and
• %ORACLE_HOME%\bpel\system\xmllib\fault-policy.xsd
  

Fault bindings
The fault bindings file defines that fault policy for a specific file so it basically just sets a default policy or specifies fault policies for a specific process:

(Open image in browser)

The example fault bindings file has the following contents:

<?xml version="1.0" encoding="UTF-8"?>
<faultPolicyBindings version="2.0.1" xmlns="http://schemas.oracle.com/bpel/faultpolicy" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<!-- Enabling this will cause all processes in this domain to use this
fault policy -->

<process faultPolicy="DefaultPolicy"/>

<!-- DefaultPolicy is defined in ./fault-policies/DefaultPolicy.xml -->
<partnerLink faultPolicy="DefaultPolicy">

<!-- Enabling this will cause all invoke faults at partner link
name of "creditRatingService" to use fault policy with
id id = DefaultPolicy -->

<name>creditRatingService</name>

<!-- all invoke faults at partner link below port type use fault policy
with id = DefaultPolicy

The following entry covers the samples/tutorials/122.DBAdapter/InsertWithCatch sample. -->

<portType xmlns:db="http://xmlns.oracle.com/pcbpel/adapter/db/insert/">db:insert_plt</portType>
</partnerLink>
</faultPolicyBindings>

Fault policies

The fault polices file defines the action that will occur when a fault binding triggers. An action is defined as:

(Open image in the browser)

The actions provided are:

1. retry - retry the operation "retryCount" times pausing "retryInterval" seconds between each iteration. If exponentialBackoff is set the "retryInterval" will be increased exponantially. "retryFailureAction" specifies what will happen if the retry operation fails and "retrySuccessAction" specifies an action to take if the retry operation is successful.
   
   
2. rethrowFault - bubble up the fault to the closest "catch" handler
   


3. humanIntervention - mark the work item to be "pending recovery from the BPEL console
   


4. abort - terminate the instance
   


5. replayScope - replay scope fault
   
   
6. javaAction - execute a custom java function

A condition is used to "select" the appropriate action to be taken.

The example and default "DefaultPolicy.xml" file has the following contents:

<?xml version="1.0" encoding="UTF-8"?>
<faultPolicy version="2.0.1" id="DefaultPolicy" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://schemas.oracle.com/bpel/faultpolicy" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">


<!-- This section describes fault conditions. Build more conditions with faultName, test and action -->


<Conditions>
<!-- Fault if wsdlRuntimeLocation is not reachable -->
<faultName xmlns:bpelx="http://schemas.oracle.com/bpel/extension" name="bpelx:remoteFault">

<action ref="ora-retry"/>
</condition>
</faultName>
<!-- Fault if location port is not reachable-->

<action ref="ora-rethrow-fault"/>
</condition>
</faultName>
</Conditions>
<Actions>


<!-- This action will attempt 8 retries at increasing intervals of 2, 4, 8, 16, 32, 64, 128, and 256 seconds. -->

<Action id="ora-retry">
<retry>
<retryCount>8</retryCount>
<retryInterval>2</retryInterval>
<exponentialBackoff/>
</retry>
</Action>

<!-- This is an action will cause a replay scope fault-->
<Action id="ora-replay-scope">
<replayScope/>
</Action>

<!-- This is an action will bubble up the fault-->
<Action id="ora-rethrow-fault"> <rethrowFault/>
</Action>

<!-- This is an action will mark the work item to be "pending recovery from console"-->
<Action id="ora-human-intervention">
<humanIntervention/>
</Action>

<!-- This action will cause the instance to terminate-->
<Action id="ora-terminate">

Good BAM Dashboard design

Recently I have been involved in constructing Oracle BAM dashboards. Usability is a important think when designing BAM dashboards and I found the book Information Dashboard Design very intresting.

In his book Information Dashboard Design, Stephen Few list common mistakes and design patterns for good Dashboards.

The book is avaliable online via Safari and here is the Amazon link





Information Dashboard Design

Book Description (From Oreilly Safari)

Dashboards have become popular in recent years as uniquely powerful tools for communicating important information at a glance. Although dashboards are potentially powerful, this potential is rarely realized. The greatest display technology in the world won't solve this if you fail to use effective visual design. And if a dashboard fails to tell you precisely what you need to know in an instant, you'll never use it, even if it's filled with cute gauges, meters, and traffic lights. Don't let your investment in dashboard technology go to waste.

This book will teach you the visual design skills you need to create dashboards that communicate clearly, rapidly, and compellingly. Information Dashboard Design will explain how to:

• Avoid the thirteen mistakes common to dashboard design
• Provide viewers with the information they need quickly and clearly
• Apply what we now know about visual perception to the visual presentation of information
• Minimize distractions, cliches, and unnecessary embellishments that create confusion
• Organize business information to support meaning and usability
• Create an aesthetically pleasing viewing experience
• Maintain consistency of design to provide accurate interpretation
• Optimize the power of dashboard technology by pairing it with visual effectiveness

Using Windows Powershell with ORACLE on Windows

Oracle Powershell is a free shell from Microsoft for Windows. As a scripting fan I thought I would take a look at it, when I needed a script to start and stop all Oracle services on a test instance.

PowerShell provides access to WMI objects such as WMI:win32_servies and Services "cmdlets" for querying and manipulating Windows Services, among them New-Service, Set-Service, and Get-Service.

The following script lists all information of services

$colItems = get-wmiobject -query "select * from win32_service where name like 'Oracle%'"

foreach ($objItem in $colItems) {
write-host "Display Name: " $objItem.DisplayName
write-host "Accept Pause: " $objItem.AcceptPause
write-host "Accept Stop: " $objItem.AcceptStop
write-host "Caption: " $objItem.Caption
write-host "Checkpoint: " $objItem.CheckPoint
write-host "Creation Class Name: " $objItem.CreationClassName
write-host "Description: " $objItem.Description
write-host "Desktop Interact: " $objItem.DesktopInteract
write-host "Error Control: " $objItem.ErrorControl
write-host "Exit Code: " $objItem.ExitCode
write-host "InstallationDate: " $objItem.InstallDate
write-host "Name: " $objItem.Name
write-host "Path Name: " $objItem.PathName
write-host "Process ID: " $objItem.ProcessId
write-host "Service Specific Exit Code: " $objItem.ServiceSpecificExitCode
write-host "Service Type: " $objItem.ServiceType
write-host "Started: " $objItem.Started
write-host "Start Mode: " $objItem.StartMode
write-host "Start Name: " $objItem.StartName
write-host "State: " $objItem.State
write-host "Status: " $objItem.Status
write-host "System Creation Class Name: " $objItem.SystemCreationClassName
write-host "System Name: " $objItem.SystemName
write-host "Tag ID: " $objItem.TagId
write-host "Wait Hint: " $objItem.WaitHint
write-host

}

Starting and stopping dependent services was not as easy as I initially thought as there seemes to be no access to information about dependent services. (or?)

However the following script starts all services except any DBConsoles

$colItems = Get-Service -include "Oracle*" -exclude "*DBConsole"

write-host "Starting ORACLE Services"
foreach ($objItem in $colItems) {
if( $objItem.Status -eq "Running") {
write-host "Service " $objItem.DisplayName " already started"
} else {
write-host "Starting service " $objItem.DisplayName "."
Start-Service -displayName $objItem.DisplayName
}
}

Get-Service -include "Oracle*"

The script produces the folowing output when run:

BPEL PM Java tuning & 64 Bit setup

I recently updated the JVM and added 64 bit support to a Solaris T1 box, this are the instructions:

1. Download the correct Solaris installation from http://java.sun.com/javase/downloads/index_jdk5.jsp

I used Java JDK 1.5.0_11 in this case.

The two files to download are:

32 bit version - jdk-1_5_0_11-solaris-sparc.sh
64 bit plugin - jdk-1_5_0_11-solaris-sparcv9.sh

2. CD to $ORACLE_HOME for the application server

3. Unpack the installations by running the installation programs,

Command lines:

sh /oracle/install/java/jdk-1_5_0_11-solaris-sparc.sh
sh /oracle/install/java/jdk-1_5_0_11-solaris-sparcv9.sh

4. Verify that the install was done in the correct place:

bash$ ls -ald jdk*
drwxr-xr-x 9 oracle oinstall 512 Feb 16 18:15 jdk
drwxr-xr-x 9 oracle oinstall 512 Feb 19 11:54 jdk1.5.0_11

5. Create a backup of the OPMN configuration $ORACLE_HOME/opmn/opmn.xml

cd $ORACLE_HOME/opmn/conf
cp opmn.xml opmn.xml_`date "+%y%m%d%H%M%S"`

6. Edit $ORACLE_HOME/opmn/conf/opmn.xml

Find the XML Element with the content process-type id="oc4j_soa"
and edit the bold sections (three changes in bold):
(libumem and -D64 is optional of course)

<process-type id="oc4j_soa" id="OC4J" status="enabled">
<environment>
<variable id="LD_PRELOAD_64" value="/usr/lib/64/libumem.so.1">
</environment>
<module-data>
<category id="start-parameters">
<data id="java-bin" value="/oracle/product/soa_10.1.3/jdk1.5.0_11/bin/java">
<data id="java-options" value="">-d64</strong> -server -Xmx2g -Xms1g -XX:PermSize=256m -XX:NewRatio=3 -XX:MaxTenuringThreshold=3 -XX:SurvivorRatio=6 -XX:-UseParallelOldGC -Djava.security.policy=$ORACLE_HOME/j2ee/oc4j_soa/config/java2.policy -Djava.awt.headless=true -Dhttp.webdir.enable=false -Doraesb.home=/oracle/product/as/as_10.1.3/integration/esb -Dhttp.proxySet=false -Doc4j.userThreads=true -Doracle.mdb.fastUndeploy=60 -Dorabpel.home=/oracle/product/as/as_10.1.3/bpel -Xbootclasspath^/p:/oracle/product/as/as_10.1.3/bpel/lib/orabpel-boot.jar -Dhttp.proxySet=false"/> </category>

The variable LD_PRELOAD_64 means that a different memory allocator called lubumen is used. This memory allocaor is designed for multi-cpu and multi-core processors.
It is recommended by Sun here and here for T1 machines.

For more information on libumem and similar Linux allocator see my link collection here.

7. Save the file and validate the change with opmnctl.

% opmnctl validate opmn.xml

8. Restart the application server.

Also se metalink note:368973.1.

How do I create a new user in Oracle SOA Suite and give it permission to domain xyz.

Based on the documentation avaliable here we need to perform the following steps, if we have a "standard" soa suite advanced install:

1. Create the domain xyz
2. Create a group/role "BPMxyzDomainAdmin"
3. Create a user "myxyzuser" and grant the role "BPMxyzDomainAdmin" to the user
4. Assign the domain admin permission to the "BPMxyzDomainAdmin" role by running
   cd ORACLE_HOME\j2ee\oc4j_soa
   java -Xbootclasspath/a:c:\oracle\soa\bpel\lib\orabpel-boot.jar -jar ..\home\jazn.jar -grantperm jazn.com -role BPMxyzDomainAdmin com.collaxa.security.DomainPermission xyz all
5. Restart
6. Done - now the user should be able to login to the xyz domain but not any other domain
   http://host:7777/BPELConsole/xyz/index.jsp

Important to note in step 4 is that we "cd" to the oc4j_soa OC4J container before we run the command, this way the jazn files in that domain is updated.

Edit 080225: Note that the users still need admin permission for deployment/undeployment to work from ant scripts and the like. Eg: you need to grant oc4j-administrators etc

New data object in BPEL 10.1.3 for getVariableData

In 10.1.2 we could use the following to get variable data in bpelx:exec and custom xpaths:

Element ssn = (Element)getVariableData("input","payload","/tns:ssn");
But this seemes to have changed in 10.1.3 to

import oracle.xml.parser.v2.XMLNode
firstName = ((XMLNode) getVariableData("inputVariable","payload","/client:TestCaseProcessRequest/client:SurName")).getText();

I guess this means that the XML parser has been changed to the Oracle XDK, which is good news since it is a lot (10x) faster than the old OSS parer.

Implemented as an open-source plug-in to Microsoft's Visual Studio.NET 2005, NORMA requires at least the standard version of Visual Studio 2005. For further details on the ORM 2 graphical notation, see ORM 2 Technical Report 1. A technical preview of NORMA is available on SourceForge. The software is currently in the pre-beta stage, but extensive functionality enhancements and user-interface improvements are planned for the near future. Currently the tool supports entry of ORM2 schemas, verbalization of of most constraints, and code generation (for basic constraints) to a variety of DBMSs (including SQL Server, DB2, Oracle, and PostgreSQL) as well as class models and XML schema. NORMA is capable of importing ORM schemas entered in Visio for Enterpise Architects, but the diagrams need to be laid out manually.
