ATG Order update - InvalidVersionException and ConcurrentUpdateException

ATG repository item descriptor can have the version property. The atg.adapter.gsa.ItemTransactionState holds this version information. For example consider the Order item-descriptor. It has the version property defined against the table dcspp_order. Means, the dcspp_order table has the column version which defines which version of order is currently in the DB. Each order update flow will update this column.

 <property name="version" display-name-resource="version" data-type="int" queryable="true" readable="true" column-name="version" hidden="false" category-resource="categoryInfo" expert="true" required="false" cache-mode="inherit" writable="true">
    <attribute name="uiwritable" value="false"/>
    <attribute name="propertySortPriority" value="30"/>
  </property>

-------------------------------

During the OrderManager.updateOrder() call, validation is done to compare the vesion of the Order object to the one in repository and the exception atg.commerce.order.InvalidVersionException is thrown.
 
2012-09-08 11:38:24,213 99015942 ERROR [nucleusNamespace.atg.commerce.order.OrderManager] (TP-Processor77:) InvalidVersionException: Unable to update order for :6226680554
2012-09-08 11:38:24,213 99015942 ERROR [nucleusNamespace.atg.commerce.order.OrderManager] (TP-Processor77:)
atg.commerce.order.InvalidVersionException: This order (6226680554) is out of date. Changes have been made to the order and the operation should be resubmitted. Order version 136, Repository item version 138.
    at atg.commerce.order.OrderManager.updateOrder(OrderManager.java:2557)

--------------------------------   


During the order update @ GSAItemDescriptor, atg.repository.ConcurrentUpdateException is thrown if no row got updated based on the "where" condition. If the table is having a version property, the where condition includes the version also. And in case of Order, this exception may occurs if the version in the DB not matches with the one in order object.

    How to avoid InvalidVersionException and ConcurrentUpdateException ? Does one need to wrap all update, insert order statements in begin and end transaction code ?

    InvalidVersionException and ConcurrentUpdateException will occur due to bad coding/ bad server configuration / clustering.

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 ...

Eclipse plugin: InstaSearch – for quick search

InstaSearch is an Eclipse plug-in for performing quick and advanced search of workspace files. This will index the files and when you search for some file contents, it will look with in this index and the search results will be faster, just like the Goolge instant search. It uses Lucene ( http://lucene.apache.org/ ) for indexing and fast searching of files in the workspace. Each search result file then can be previewed using few most matching and relevant lines. A double-click on the match leads to the matching line in the file. Main Features Instantly shows search results Shows a preview using relevant lines Periodically updates the index Matches partial words (e.g. case in CamelCase) Opens and highlights matches in files Searches JAR source attachments Supports filtering by extension/project/working set Download / Installation In Eclipse Helios (3.6) please install using the  Eclipse Marketplace from the Help menu http://marketplace.eclipse.org/s...

ATG CA - BCC home screen : how to add a new link

          Activity source is the property which controls the links on the left nav on the BCC home screen. All activity sources are registered with the ActivityManager component at /atg/bizui/activity/ActivityManager . When rendering the BCC home page, the ActivityManager cycles through all the registered ActivitySource components and displays left navigation links for each of them on the BCC home page. For example if I want to add a new link "My New Link" , below screen shots exaplins how this can be done 1. Add  activityManager.properties to specify the activityresources. In this  activityManager, I specified one MyActivitySource. 2. Add  MyActivitySource.properties  to specify the name of the link and the other details . Here it refers to a bundle properties file.  3. Add  the bundle properties file  to specify the name of the link.  4. Now you could see the new link...
