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atg.commerce.order.InvalidVersionException: This order (6226680554) is out of date.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.

--------------------------------   


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.

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

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

ATG search installation and search engine log files

Here I would like to explain how your ATG search folder structure looks like after you do the ATG search installation and also about the search engine log files. To get the ATG search, you need to install the ATGSearch<version>Windows.exe after you do the ATG installation. When you install ATG search, the generated folders include an OS dependant folder. In the below screen shot, you could see the "i686-win32-vc71" folder and this is generated since the ATG search ins installed in a windows machine. The ATG search engine is actually an exe file inside this "i686-win32-vc71" folder. Below screen shot give you an idea about the "atgsearch.exe", which is the search engine application. This search engine application (atgsearch.exe) is started by a remote launcher call from the BCC search administration UI.  The log files like "atgsearch_20120106112413_568.log" are the search engine log files where you could see the engine ...

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 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...
