No results found is a common response to a search request, but how do you detect this in your BPM process ?
A “No Results Found” situation causes an exception to be thrown which means you can detect it using an intermediate error event, but you need to be able to handle a real errors as well as a no results found which is a special kind of exception.
Here we have a simple example of a search human service which applies equally to Physical and Virtual MDM Server.
There is an intermediate error event attached to the do search nested service that calls the MDM Search integration service. The gateway decision determines whether it is a no results found or not.
To determine how to configure the decision gateway we need to have a look at the format of the exception we get when a no results found is generated and this differs slightly between virtual and physical MDM Server.
Handling a Virtual MDM Server response
A sample of part of the xml format of the exception is shown here
Here is is the reason code we are interested in. So the decision gateway configuration looks like this
The decision logic being
extracts the reason code and checks for ENOREC.
Handling Physical MDM Response
The implementation remains the same, the test within the decision gateway needs to be altered as the location of the reason code is different to virtual. In this example the reason code that is checked is applicable to a Party or Person Search, however it is possible that the reason code will be different for different types of physical search.
A sample of part of the xml format of the exception is shown here
Here we see the reason code we are interested in is nested under the <errors> tag within an < element>.
So in this case we need the decision logic to be

InfoSphere Master Data Management operational server v11.x OSGi best practices and troubleshooting guide
Dany Drouin 270004VXKT Visits (3626)
InfoSphere Master Data Management operational server v11.x OSGi best practices and troubleshooting guide
Note: This preview only covers the initial set up of the MDM Workbench. The
The goal of this article is to show best practices and optimal development practices for developing with the InfoSphere MDM operational server. We will discuss common OSGi patterns, troubleshooting, including failures and resolution, as well as how to best deploy MDM composite bundle (CBA) extensions.
The InfoSphere MDM version v11 operational server is based on an enterprise OSGi architecture, which is modular in nature. The benefits of a modular architecture application design include reducing complexity, reducing time to delivery, and increasing serviceability. The Java EE infrastructure leveraged in previous versions of InfoSphere MDM had limited ability to enforce or encourage a modular design.
The advantage of a modular MDM application is to allow customization to be deployed without having to alter the core MDM application. Instead, customizations are attached in the form of extensions to the core MDM application. This is done using composite bundles, or CBA files.
Optimal workspace operational server configurations
The InfoSphere MDM Workbench is a tool that supports development of customizations and extensions to MDM operational server. The MDM Workbench allows you to define the desired data model and transactions and then generates the code required to implement the MDM Server extensions.
When using workbench to build and deploy your MDM customizations and extensions, there are a few workspace configurations to consider for achieving the best performance and development experience.
If you've used previous versions of the workbench, one of the first changes you'll hit is that you no longer need to run the developer environment setup tool when you create a new workspace. In version 11, no projects need to be imported into the workspace, and you use the same installer to setup a local test server on your development machine as you would to install a production system.
Full development environment install
If you have a completely clean machine, the simplest way to get started is to use the workbench typical install. This will install DB2, Rational Application Developer, and WebSphere Application Server, along with MDM Server and the workbench, i.e. everything you need for a full development and test environment in one go. Here's how to get everything ready to run a typical install...
Firstly, you'll need to download all the typical install images. The following part numbers are required for a full MDM Workbench v11 typical install:
CIM6NEN, CIM6PEN, CIR9NML, CIR9PML, CIR9QML, CIR9RML, CIR9SML, CIR9TML, CIR9UML, CIR9VML, CIE5FML, CIE5GML, CIE5HML, CIE5IML, CI6XNML, CI6XPML, CI6XQML
Important: If you are about to install MDM but downloaded the install images before 17th October 2013, you must download the product refresh first.
Once you have all the install images downloaded, the contents must be extracted into a specific dire
After extracting all the install images, open the install launchpad, which you can find in the MDM\disk1 directory (there are 32 and 64 bit versions). The typical workbench install link is right at the bottom of the launchpad:
When the install starts, you should be able to click through all the panels without changing anything:
Make sure you confirm that the IVT tests pass at the end of the install and, if they did, you're ready to start developing for MDM v11!
Note: you should change the defa
Workbench only install
If you don't want a local server to test changes on, installing the workbench is much quicker, since DB2, WebSphere Application Server and the server install are not required. In this case, you'll only need the following part numbers:
CIM7CML, CIR9TML, CIR9UML, CIR9VML, CIE5FML, CIE5GML, CIE5HML, CIE5IML
The launchpad doesn't support this scenario, so you have to install Installation Manager manually, add
Alternatively, you can use the Installation Manager command line to install Rational Application Developer and the workbench in one step. For example, assuming you extract the install images in the same structure as for a typical install:
imcl install com.
A typical install is ideal for demos or evaluating MDM but to set up developer environments I would recommend installing manually. You'll also need to do this if the typical install does not support your environment. The following blog post describes the manual install process:
There is also a wiki page with an up-to-date* list of install related information.
(* Please update it if it's not up-to-date!)
From an early MDM Workbench news site, the MDM Developers community has evolved and grown to a group of over 200 members, and it would be great to take a break from the usual posts and forum discussions to find out more about some of you with a quick blog interview. Whether you're a new member or a long term contributor, please say hi and tell us a little about yourself.
Feel free to leave a comment and answer any of the following questions that resonate with you, or add your own questions instead. This is just a casual blog interview and meant to be more like a real world conversation, rather than a formal resume or biography!
For fun, and a bit of encouragement, I have a few limited edition MDM Developer community stickers to give away!
Here are a few questions to get you started:
Update: Unfortunately no one replied in time to claim the ticket that prompted this blog post. Luckily if you're one of the first to reply, you could still get one of these, much more exclusive, MDM Developers stickers!

The alternative is to manually install the MDM Workbench for MDM configuration and development, and an Operational Server for test purposes.

The instructions below assume that you do not have any of the prerequisite software installed but, if you do, just skip the relevant steps.
To avoid problems with path lengths, special characters, or Windows virtualised directories, I installed all the software under a C:\IBM directory.

Installing Installation Manager
I ran install.exe to install Installation Manager in GUI mode. After installing Installation Manager you can add the required repositories individually before you run each install, as I did in the video series, or you can add all the repositories in one go as follows.
Create a repository.config file in the directory where you extracted the install images. Copy and paste in this content:
Edit any paths based on the directories you used before saving the file. Now you can add this single repository using the Installation Manager repository preferences and all the packages will show up on the install page.
For more information about Installation Manager, see the Inst
Note: you may have seen a suggestion to alter Installation Manager's agent data location using the cic.appDataLocation configuration setting, however it is not typically necessary, or a good idea, to change this setting.
Installing the workbench
Installing the workbench is straightforward once you've added the Rational Application Developer and workbench repositories to Installation Manager. Pick a suitable install location, for example C:\IBM\SDP, and you can accept the defaults for everything else.
In the MDM
Installing Operational Server prereqs
Before installing the MDM operational server, you need to install DB2 Enterprise Server Edition version 10.1 and WebSphere Application Server 18.104.22.168. In addition, the Installation Startup Toolkit provides the database scripts you'll need to create an MDM database.
You can watch how to run these installs in the MDM
Important: you must install DB2 in a directory called SQLLIB, otherwise the operational server install will not work. For example, I installed DB2 to C:\IBM\SQLLIB
I accepted most of the defaults in the DB2 install wizard, except that I chose not to enable email notifications or operating system security since this is for a development environment.
WebSphere Application Server and Installation Startup Toolkit
Both of these are installed using Installation Manager so I installed them at the same time. (You could even install them at the same time as the workbench to save time.)
Important: you must install fix pack 2 for WebSphere Application Server 8.5 otherwise the MDM install verification tests will fail.
I changed the install locations, to C:\IBM\AppServer and C:\I
Preparing to install the Operational Server
There are several advantages to manually installing a development and test environment, however the biggest disadvantage compared to a typical install is that the installer does not create an MDM database or WebSphere profile for you. Instead, you have to prep
These are the steps I followed, which are covered in the MDM
Edit SQL files
There are a couple of SQL files provided in the startup toolkit for creating an MDM database on DB2:
Both these files contain placeholders which need to be replaced with suitable values before use. These are the values I used:
Notes: Authority will be granted to the user specified by the <DBUSER> value, so this should be different to the user running the scripts. The database name is easy to specify in the installer but here I used the default. The tablespace names need to match the settings used by the installer, and the easiest way to do that for a development environment is to use the values shown above.
The following PowerShell command will fill in the placeholders and I ran it for CreateDB.sql and CreateTS.sql rather than editing the files by hand:
powershell -command "(Get-Content C:\I
After editing the SQL files, I ran them using this command in a DB2 Command Window:
db2 -v -td; -f C:\t
And the same for CreateTS.sql.
Create application server profile
I used the advanced option when creating an application server profile using the Profile Management Tool. I chose not to install the default application, gave the profile a meaningful name and picked the Development tuning setting. Administrative security must be enabled for MDM, and the advantage of creating the profile yourself is that you get to choose the username and password. If you run the Profile Management Tool as administrator, you will also be given the option to run the server process as a Windows process, which isn't necessary for a development environment.
Important: When creating a profile for use with the MDM Workbench, make sure you create it in the default location with a directory name that matches the profile name.

In Version 11 of InfoSphere MDM, some big changes happened. One change that might leave you scratching your head is the addition of new and changed terms for some familiar components. We also have a couple new components, so those might be unfamiliar too. Let's take a quick walk through the changed terms to get you started.
The first thing that you'll notice is an emphasis on capabilities rather than product names. You might not see these familiar product names anymore:
InfoSphere MDM Server
Initiate Master Data Service (MDS)
Other Initiate product names
Instead, you’ll see references to technical capabilities that those products achieve:
You might be wondering what exactly these technical capability terms mean. You can use virtual, physical, and hybrid MDM to manage your master data, whether you store that data in a distributed fashion, in a centralized repository, or in a combination of both.
The following definitions show the differences and the relationships among the technical capabilities:
The management of master data where master data is created in a distributed fashion on source systems and remains fragmented across those systems with a central "indexing" service.
The management of master data where master data is created in (or loaded into), stored in, and accessed from a central system.
The management of master data where a coexistence implementation style combines physical and virtual technologies.
Server and engine terms
Another new area that you’ll notice is a unified server, which is referred to by one common term:
The former InfoSphere MDM Server and the former Initiate Master Data Service are combined to share a single infrastructure in the application server. That single infrastructure is called the MDM operational server or operational server for short. The operational server is the software that provides services for managing and taking action on master data. The operational server includes the data models, business rules, and functions that support entity management, security, auditing, and event detection. For detailed descriptions and diagrams, see the arch
Records, member records, and entities
Finally, the concepts of entities and records were clarified:
A single unique object in the real world that is being mastered. Examples of an entity are a single person, single product, or single organization.
The storage representation of a row of data.
The representation of the entity as it is stored in individual source systems. Information for each member record is stored as a single record or a group of records across related database tables
Depending on your implementation style, these concepts reflect the technical capabilities of virtual, physical, and hybrid MDM. For example, an entity in virtual MDM is assembled dynamically based on the member records by using linkages and then is stored in the MDM database. Conversely, an entity in physical MDM is based on matching records from the source systems that are merged to form the single entity. For details, see the diag
I’ll leave a discussion of hybrid MDM to a future article. If you’d like to read some conceptual topics about hybrid MDM now, see its technical overview.

MDM AE pMDM with RESTful web services
Previously, interactions with MDM Operational server were possible with EJB/RMI, JMS, JAX-WS and JAX-
Possible payloads that are accepted are application/xml and application/json. JSON support was added in v11.4 FP1.
It is important to note that all REST interaction are using one RESTful service “MDMWSRESTful”, PUT method type only and accessed via URI http
The same xml request/response payload used for EJB/RMI is used for REST interactions.
For the full list of capabilities and supported request headers consult the following documentation link:
Interacting with MDMRESTful service
Here’s a sample client leveraging Apache Wink demonstrating an MDM RESTful call:
The above code will submitting an MDM xml payload and expecting back an xml response.
This is determined by the ‘Content-type’ and ‘Accept’ http header properties.
Here’s a look at a getParty xml payload and response:
The same request/response as JSON, using application/json, as both content-type and accept:
The default MDM JSON model is actually based on the core XML schema model (MDMCommon.xsd and MDMDomains.xsd). Internally, MDM will validate the JSON using these schemas.
We use a “Mapped notation” api to build the JSON. A couple things to note about this implementation:
Don’t want to write any code to test your MDM services?
Choose “PUT” as the HTTP method

MDM Application Toolkit for Product Domain
I recently had to build a product bundling process for a demo using BPM and the MDM Application Toolkit(MDMAT). Having built many business processes over the past 2 years using data from InfoSphere MDM I realized this was going to be the first one I that I was to build against the product domain of the physical engine. Using the MDMAT against the Party domain is pretty darn easy and very quickly a rich process can be built that interacts with MDM's library of web services for many different types of processes. How useful would it be for me when operating against the Product Domain, especially when a good chunk of my data was stored in Product domain XML soft specs? Well I'm pleased to say it was also very straight forward. I've written some notes below that will hopefully allow others to also find it just as easy to use the MDMAT against the product domain.
The process was to execute a search against the MDM product domain using some pre defined criteria that would allow me to pull back all products that met a certain criteria. in this case it was to retrieve a list of products that were within the 'Mobile Phone' category of the 'Channels' hierarchy, were aimed at a 'Market Segment' that was 'Affluent' had an 'Effective Date' before today's date and an 'Expiry Date' that was after todays date. This would allow me to show currently active offers on the mobile channel for Affluent customers. The 'Market Segment', 'Effective Date' and 'Expiry Date' attributes were all stored as attributes within an XML spec called 'Offer Attributes'. In the search results that come back from MDM I also needed to pull out some additional attributes that were stored within another XML spec called 'Channel Mobile Phone', these attributes were named 'Mob
Whenever I build a business process I first start by defining the variables that I will need. Since BPM applications are data driven, I find it helpful to define the data upfront and then worry about wiring them into a process at a later stage. Using the MDM Workbench I exported my MDM WSDL and imported it into Process Designer. This gives me access to my MDM Product business objects within BPM, allowing me to easily construct a ProductSearchBobj object with the criteria I need to execute my search and also create a Prod
With the objects defined I could move on to define my process flow. I created a very simple flow to suit the requirements as seen below:
I would first use the 'Configure Spec Search Criteria' node to execute a script to populate the ProductSearch object with the crieteria I needed. I would then configure the 'Retrieve all Offers' node to use the MDM Application Toolkits' Physical MDM Txn service to execute a search an return a list of Prod
With my objects defined and my process defined all I had to do was a little bit of scripting to firstly populate my search and then extract my search results to populate my displayObject. (I had already populated my MDMConnection object with my MDM server's credentials and configured the 'Retrieve all Offers' node to use the MDM Application Toolkit's Physical MDM TXn service to call an MDM 'sea
Populating the Search
I wrote a simple script in my 'Configure Spec Search Criteria' object to pass in the search criteria. I wont include the full script here, but all I had to do was create an instance of a ProductSearch object and set the following attributes:
When passed into the 'Retrieve all Offers' node my search criteria successfully results in a list of products that I am interested in being returned as a list of Prod
Extracting the spec values and populating the display object
Up until now everything I had done was pretty similar to other processes I had built, this final piece was the most challenging, in that I had never extracted values from an XML spec before within a business process. Looking at my Prod
With my spec values now populated inside my Prod
This ended up being a bit of a longer blog post then I intended (sorry JT), but hopefully it will provide you a good starter in using the MDMAT for the product domain. I really enjoyed building this process (and writing this article) as it showed me how cool the MDMAT is for helping me to build MDM centric business processes. The ability to build processes against MDM and not worry about the connection and any complexity in calling MDM Web Services saves a huge amount of time and with a little bit of script I was able to leverage the value of MDM's XML specs. if you want more information drop me an email. I'd love to hear what you are doing.

You must have faced quite a good amount of code generation issues if you are working on MDM Server v8 or v8.5. One of the main problems that I have faced was whenever we do not have a hold on the OOTB code generation technique. Say if you need to have OOTB TCRM
Errors logged during code generation
Errors occurred during execution
Error executing tag handler: java
Another problem which we face is, MDM does not support the Transient Object code generation in v8 or 8.5 Hence we have land up with no other option other than to create an Entity, its corresponding classes and will not be persisted. It would be used as a wrapper object. Therefore, your project may have unnecessary files which you may not use in MDM framework.
By this approach it helps the developer to have a strong hold on how your service description should be by writing your own WSDL and generating the java code based on the definition in the WSDL. Definitely, this approach would be challenging as it will not be as simple as clicking the Generate Code in the MDM Model Editor
RAD : 22.214.171.124
MDM : MDM Server v 8.5
WAS : v6.1
Creating Top-Down Web Service
Web services can be created using two methods: top-down development and bottom-up development. Top-down Web services development involves creating a Web service from a WSDL file.
When creating a Web service using a top-down approach, first you design the implementation of the Web service by creating a WSDL file. You can do this using the WSDL Editor. You can then use the Web services wizard to create the Web service and skeleton Java™ classes to which you can add the required code.
Although bottom-up Web service development may be faster and easier, the top-down approach is the recommended way of creating a Web service. By creating the WSDL file first you will ultimately have more control over the Web service, and can eliminate interoperability issues that may arise when creating a Web service using the bottom-up method.
The tools that help to generate the web service artifacts are WSDL2JAVA.bat and JAVA2WSDL.bat.
WSDL2JAVA generates the web service skeletons and the deployment descriptor templates against a WSDL. This is used for the top down approach
JAVA2WSDL generates WSDL from the Java class. This is used for bottom up approach.
This document helps you to create a top to down EJB implementation of Web Service for MDM services. It is quite simple to develop a web service with the help of Web Service editor that is available with the RAD.
By the end of this document, you will be able to create an ejb web service implementation from WSDL to invoke MDM services.
Note: We need to have manual effort to bring up the web service project structure in sync with the classes and the class names that gets generated with the help of MDM model editor.
RAD Preference Settings
Prior to developing the Web Service, you need to set certain Preferences in RAD.
1. Windows > Preferences > Web Services > Resource Management
Note: It is a good practice to select this option when you use utility JAR files or third party libraries, in order to avoid these loadable Java Classes that have to be regenerated.
Below are the steps which explain how to create a top down EJB web service implementation:-
Click Next > Generates the Web Service skeleton from the WSDL and publishes the project to the server
Note:- Start the server before generating the web service
i. Move the SearchBindingImpl to Proj
ii. Rename the below files:-
SearchBindingImpl -> SearchServiceBean
iii. ejb-jar.xml ->
a) Modify the mapping of
ix. If you have defined wrapper object in WSDL to hold any OOTB objects, make sure you create the BObj, Converter and Constructor for the same.

When using InfoSphere Master Data Management (MDM) customers will see coredumps being created when an application server is being started or stopped in an environment with multiple application servers.
There are several use cases that can lead to this behavior, all involve a WebSphere Application Server topology of more than one JVM in a clustered or non-clustered environment.
- JVMs recycle by themselves no apparent cause
This issue has been identified by Red Hat Linux Support as a defect Bug 1327623 - replacing .so which was opened and closed, leads to segfault on next dlopen/dlsym.
Diagnosing the problem
The javacore and heapdumps will have two things in common:
1. The crash occurring in the ld-l
Resolving the problem
In order to have immediate relief to this issue a workaround is available.
Follow steps below:
1. Stop any JVM that has the core MDM application installed

You may have seen the recent tech talks that the team here have been producing for our clients. In these tech talks an IBM expert will talk through a specific MDM topic in great detail sharing the deep expertise of the architects and developers that are living and breathing the technology. These tech talks are provided for free and just require a simple registration process to allow you to attend. All sessions are recorded and replays will be available shortly afterwards.
One area of keen interest to our clients has been concerning the Stewardship and Governance capabilities provided by MDM, specifically the IBM Stewardship Center, that was released in MDM 11.3. So it falls to me to host the next MDM tech talk on June 23rd. In this session I will be discussing the new capabilities offered by the IBM Stewardship Center, how we are changing the game for stewardship teams looking to evolve their organization to be more reactive to data quality events, engaging line of business users to provide input to data quality issues and adding advanced business rules and intelligence to automate events from across the entire data quality landscape.
A one hour tech talk is no where near enough time to do such a broad and important area justice however, we will spend some time up front explaining IBM's perspective on Information Governance and how IBM's InfoSphere portfolio provides the market leading integrated suite of comprehensive governance capabilities that can flex to suit your specific industry requirements. We will dive into the IBM Stewardship Center and its comprehensive workflow engine, providing collaboration and orchestration across the enterprise and touch on the MDM Application Toolkit, a suite of accelerators designed and built by some of our development ninja's to make creating custom governance workflows and quick and easy experience....and if we have time we may even have a live demo of the latest version of the Stewardship Center. During the session the live chat will be open allowing you to ask questions and I will have a team of experts ready to respond in real time.
If your organization is trying to address the growing focus on Information Governance, if you are trying to figure out how to make your Stewardship organization more efficient, or you just wanted to take a look at one of the coolest new features from the MDM team then don't miss the Mast
