Evergreening

Evergreening is one part of DWL application. As the name suggests that its motive is to keep the information always up to date. This is basically a matching process where information of customers coming from different sources are matched implementing some logic. Ever greening is run 24/7.  As per the degree of matching between records the matches are divided into three classes:

·         A1 match

When there is a very high degree of matching between two or more records then it is called A1 match. Whenever there is any A1 match between records then these records are merged and one single record is generated as per logic.

·         B match

This is also known as “LEVEL 2” match. Here the degree of matching is less than A1. When this match is found between records then some additional processing is performed on the records.

Locating and importing the InfoSphere MDM Probabilistic Matching Engine model

The InfoSphere® MDM Probabilistic Matching Engine model consists of the data model definitions and associated algorithms that are used for matching MDM data.

About this task

The model definitions and matching algorithms can be extracted from com.ibm.mdm.mds.pme.configuration_11.x.x.jar bundle located in the <workbench install folder>\com.ibm.mdm.tools\server_bundles\mdm\ folder.

Procedure

1. Extract the contents of the com.ibm.mdm.mds.pme.configuration_11.x.x.jar file to a local file system, then extract the resultingmdmpme.config.zip file.
2. In the MDM Workbench, in the MDM Configuration perspective, click Master Data Management > New Configuration Project.
3. Specify Party as the project name to create a new virtual MDM project with the name Party.
   Note: By convention, the new project name should be the same as the name of the .imm file that is part of the import.

   If a different name is required, the configuration element /IBM/BusinessServices/PME/configuration will need to be modified accordingly. For more information, see Specifying a different InfoSphere MDM Probabilistic Matching Engine configuration
4. Click Next to continue and accept all default selections.
5. Delete the party.imm file that the New Virtual Hub Project wizard has just created.
6. Exit, then restart the MDM Workbench.
7. Select File > Import, then select General > File System as the import source.
8. To define the From Directory, browse and select the configuration directory extracted from the mdmpme.config.zip file. Select all the contents of the directory to import.
9. Specify Party as the Into Folder.
10. Click Finish. The Workbench will import all of the selected files.
11. If you are asked if you wish to overwrite existing files, select Yes.
    Tip: If you are importing over an existing configuration and encounter errors during the import process, delete the .alg and .imm files, then reimport the project.
12. Refresh the Party project in the MDM Workbench.

Configuring the InfoSphere MDM Probabilistic Matching Engine in the Configuration and Management component

There is nothing you need to do to enable suspect processing with InfoSphere® MDM Probabilistic Matching Engine in the configuration repository. However, you do need to make sure that the InfoSphere MDM Probabilistic Matching Engine indices are kept synchronized with InfoSphere MDM data.

About this task

The index synchronization is configured using the configuration element /IBM/DWLCommonServices/DerivedDataSynchronization/enabled.

Procedure

In the Configuration and Management component, edit the value of the configuration element /IBM/DWLCommonServices/DerivedDataSynchronization/enabled to ensure that the value is true.

Note: The default value of this configuration element is false.

By changing the value of /IBM/DWLCommonServices/DerivedDataSynchronization/enabled to true, the InfoSphere MDM Probabilistic Matching Engineindices will be kept synchronized with InfoSphere MDM data.

Resolution:

Since it looks like it's referring to a schema , go to the server,

Application servers > server1 > Process definition > Java Virtual Machine

Check to see teh classpath is having the references to the CustomerResources/../..xsd and properties that are part of the current workspace. 

If so , make sure they are updated and don't have any discrepancies.
