Book review : Oracle SOA Suite Developer's Guide

Oracle SOA Suite Developer's Guide Finally i had some spare time to read this nice book! It's real bookshelf filler with 621 pages.

Oracle Service Bus, publish small/big messages to Oracle AQ endpoint

The weird thing was for certain responses i couldn't find the payload back when i queried the aq table in the database.

So the running instances will still use the current version and all new instances will be able to invoke the new deployed version of the application. As soon as all the sessions who're using the old version of the application are expired, Weblogic will recognize it...
