Problem conclusion
With the new "updateImmediately" configuration, INVENTORY Update locks are not obtained in the OrderProcess transaction. Instead, the INVENTORY rows are updated in a separate, much shorter, transaction and committed as soon as possible. If the OrderProcess transaction is rolled back, then the INVENTORY updates are reversed, also in a separate transaction. To configure this new behavior, add the following to the InstanceProperties tag in the wc-server.xml instance configuration file: <com.ibm.commerce.fulfillment.commands.InventoryUpdateHelper updateImmediately="true" /> ------------------------------------------------------------- The latest available maintenance information can be obtained from the Recommended Fixes for WebSphere Commerce technote: http://www.ibm.com/support/docview.wss?rs=3046&uid=swg21261296
