Search engine shutdown call from the Estore instnace

 When the estore or commerce instances are restarted the routing system service can send shut down requests to stale engines, this can be caused because of any of the following.

1. Some other instance marked the engine as stopped in the DB (This can be caused because the machine could not reach the host running the engine)
2. The eStore instance is using a different search schema that has data about the search engine host and is marked as stopped in that DB.

To avoid this overrride \atg\search\routing\RoutingSystemService.properties by setting
cleanUpStrayEng=false.

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.

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 @...
