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 - more about Forms and Form Handlers

An ATG form is defined by the dsp:form tag, which typically encloses DSP tags that specify form elements, such as dsp:input that provide direct access to Nucleus component properties. Find below a sample dsp:form tag.    <dsp:form action="/testPages/showPersonProperties.jsp" method="post" target="_top">      <p>Name: <dsp:input bean="/samples/Person.name" type="text"/>      <p>Age: <dsp:input bean="/samples/Person.age" type="text" value="30"/>      <p><dsp:input type="submit" bean="/samples/Person.submit"/> value="Click to submit"/>    </dsp:form>   When the user submits the form, the /samples/Person.name property is set to the value entered in the input field.Unlike standard HTML, which requires the name attribute for most input tags; the name attribute is optional for DSP form element tags. If an input tag omits the n...

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 ...

ATG - quick reference to commonly used DSP Tags

In this blog, I would like to give a quick reference to the most commonly used DSP Tags.Note that in this DSP tag details : bean refers to a Nucleus path, component name, and property name param refers to a Page parameter value refers to a Static-value var refers to a EL variable id refers to a scripting variable ============================================================== 1.dsp:importbean     example: <dsp:importbean bean="/atg/dynamo/droplet/Switch"/> ============================================================== 2.dsp:page     usage: It encloses a JSP. The dsp:page invokes the JSP handler, which calls the servlet pipeline and generates HTTPServletRequest.    example:    <dsp:page> ..... </dsp:page> ============================================================== 3.dsp:include     usage: Embeds a page fragment in a JSP.     example:   <dsp:include src="/myPage/Result...
