ATG Search - how the search rules are deployed as refinement config xmls during search indexing

The rules that make up the search configurations are created in ATG Merchandising and stored as repository items in the RefinementRepository. When the product catalog is deployed from the ATG Merchandising environment to the target site, the RefinementRepository is deployed as well.

For the soap call from the commerce instance to the search engine, for text queries we normally use refineConfig=”map” and the search engine itself determines the right refine config for the query.

When Search Administration initiates indexing of the product catalog, it also invokes the /atg/commerce/search/config/CatalogRankConfigAdapter component. This component is a customization adapter that manages the process of generating the search configuration files and submitting them to ATG Search.

To generate the search configuration files, CatalogRankConfigAdapter invokes the /atg/search/repository/SearchConfigurationXMLGenerator component (of class atg.repository.search.indexing.config.SearchConfigurationXMLGenerator). This component is responsible for transforming the repository items into the XML files that represents rule sets in ATG Search.

SearchConfigurationXMLGenerator calls various other components that parse the rules in the RefinementRepository and generate XML representations of those rules. These are known an the refinement  config xmls. You could find below a sample refinement config xml :


<?xml version="1.0" encoding="UTF-8"?><!--This refinement configuration was automatically generated by /atg/commerce/search/refinement/RefinementConfigurationXMLGenerator at May 20, 2011 8:58:19 AM--><refineConfig name="categorycat171770058" specificity="4"><mapping>cat4880034</mapping><mapping>cat171770066:catalog10001</mapping><refineElement exclude="" filter="1" id="20008" label="Brand" order="" property="childSKUs.brandName" range="false" select="" sort="count" type="string"/><refineElement exclude="" filter="1" id="35002" label="Age" order="" property="childSKUs.Age" range="false" select="" sort="count" type="string"/><refineElement exclude="" filter="1" id="20018" label="Sub-category" order="" property="sub-category.$repositoryId" range="false" select="" sort="count" type="string"/></refineConfig>

ATG Search - search engine tuning settings

In this blog, I am going to list the best tuning settings for ATG Search engine. The AESoapConfig.xml, AESoapWaspConfig.xml  and AEConfig.xml are the xmls referred below and you can find it @  <ATG_DIR>\<Searchx.x>\SearchEngine\<operating_system>\bin\ folder. (1)  Make sure that the AESoapConfig.xml's rwTimeout is less than or equal to routing's readTimeoutMs. You could find the routing's readTimeoutMs @ atg\search\routing\SearchEngineService component.               rwTimeout is the  length of time in seconds to wait before a read or write operation times out on an active connection. The number can be decreased to improve performance. However, a value that is too low could cause slow connections to be prematurely closed. (2)  Adjust the number of engine threads to match the number of CPUs available to the engine. Note that the minimal value for maxThreads and maxSpar...

ATG - how to create and deploy a new atg module

ATG products are packaged as a number of separate application modules. Application modules exist in the ATG installation as a set of directories defined by a manifest file. To create a new module, follow the below steps : Create a module directory within your ATG installation.  Create a META-INF directory within the module directory. Note that this directory must be named META-INF.  Create a manifest file named MANIFEST.MF and include it in the META-INF directory for the module. The manifest contains the meta-data describing the module. A module located at <ATG2007.1dir>/MyModule is named MyModule and a module located at <ATG2007.1dir>/CustomModules/MyModule is named CustomModules.MyModule. Within the subdirectory that holds the module, any number of files may reside in any desired order. These files are the module resources (EAR files for J2EE applications, WAR files for web applications, EJB-JAR files for Enterprise JavaBeans, JAR files of Java class...

ATG : Oracle started new discussion forum for ATG

Oracle has started a new ATG discussion forum on oracle discussion forums.  It has a main ATG section and is divided into technical and business categories. You can access the url   http://forums.oracle.com/forums/category.jspa?categoryID=503 .  After Oracle acquired ATG, this was much expected and we can hope this forum might give us a better chance to discuss our ATG doubts and more people will come and discuss about ATG. Find the ATG docs @   http://www.oracle.com/technetwork/indexes/documentation/atgwebcommerce-393465.html
