ATG Search and Search engine activity log

We could use the SearchEngineActivity log files to get the request/response to the search engine from a commerce instance. This folder is located in each commerce instance or the instances from which the call to the search engine is done. The SearchEngineActivity log file folder can be configured @ SearchEngineService component ( /dyn/admin/nucleus/atg/search/routing/SearchEngineService).


To get the log files for the search engine calls, you need to specify the SearchEngineService.dumpingRequests as true. Then you need to specify the engineActivityPath as the folder in which you need the SearchEngineActivity logs.

Below you could find my SearchEngineActivity log folder.

Each successful call to the search engine from the commerce instance will create 5 files in the SearchEngineActivity folder : namely request, response, search engineinfo, stack trace and response row.

Each file name start with a specific sequence. You could see that the file name like "2630436491482_5900002_D-179430_6072_search_request.xml"  has first part "2630436491482" a sequence number for each request to the search engine,  then "5900002" is the search engine index file logical partition id, then "D-179430_6072" is the search engine host machine name and port in which the search engine listening.

The  request and response xmls are the SOAP request and response data from the search engine. Below given a sample request xml screen shot.



The engine details log file has the search engine info, like to which search engine the call is done and the port of the engine and the elapsed time,...Below given a sample search engine info xml screen shot.


The response raw is the response xml in a raw format and the stack trace has the full trace of the class and methods called for a single search engine call.

If the call to the search engine is unsuccessful or has got some error, then the log file name will have that specific deatils. For example the file name "4739687885869_6100002_D-179430_6074_search_timeout_request.xml" indicates that there was a search engine time out occurred for this call to the search engine.

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 - basic concepts of ATG

This blog is for the ATG beginners to get some basic overview about ATG. I just given the ATG concepts as a list of numbered points for the ease of understanding. 1. At the framework level, ATG is a               java based application platform for hosting web-based applications, as well as RMI accessible business components,               with an ORM layer,               a component container,               an MVC framework,               and a set of tag libraries for JSP. 2. Art Technology Group(ATG)'s Dynamo Application Server (DAS) is a Java EE compliant application server. DAS is no longer actively developed as ATG recommends using other Java EE applications servers for its products such as BEA WebLogic, JBoss or IBM WebSphere. 3. Prior to ATG 2007, JHTML was used instead of JSP for view purpose. J...

ATG Search architectural flow : Search and Index

I would like to explain the high level ATG Search implementation architecture ( for an online store) through the above diagram. In this diagram 1.x denotes the search functionality and 2.x denotes the indexing functionality. I have given JBoss as the application server. Physical Boxes and Application Servers in the diagram ( as recommended by ATG )  : Estore ( Commerce ) Box --> The box with the estore/site ear (with the site JSPs and Java codes). Search Engine Box --> The box with the search engine application running. Indexing Engine Box --> The box with the indexing engine application running. CA (Content Administration) Box --> The box with the ATG CA ear ( where we could take CA -BCC - Search Administration and configure the search projects) . Search Indexer Box --> The box with the ATG Search Index ear ( to fetch the index data from repository). Note that the engine performing indexing will need access ...

Basic design decisions for a commerce search setup ( with an ATG Search view)

In this blog I would like to explain the basic set of configuration/design decisions needed to setup an ATG search project. Most of these design decisions are common for all Enterprise search applications. 1. Decide the searchable properties :   This means the properties that the business want the user to search in the ecommerce platform. In ATG search these are configured as the text properties in the product-catalog-output-config.xml ( the definitionFile of the \atg\commerce\search\ProductCatalogOutputConfig). Usually the displayName of product/sku, displayName of department/category/sub-category, skuId, brandName are the properties configured as searchable. 2. Decide the search refinement properties or the faceted properties :   After a user search for a keyword, search refinement is the next step done to filter his results. ATG supports the search refinement using the Faceted Search concept. Read more about facted search @...
