With the help of the EclipseLink DBWS framework it is very simple to generate Web Services based on SQL statements, a table or a PL/SQL Procedure.without knowing or writing any java code. The only thing you need to do is to configure the dbws-builder xml and use this in the DBWS generator.
One of the big problems with package solutions is that they are very database centric. Changing the data model is basically suicide for a programme. Adding a few new tables is dodgy but sometimes required and adding columns is reasonably okay but modifying the core data model is always going to get you in hot water.One area that I've seen consistently as a problem over the years though is down
Although I didn’t attend the Burton Group Catalyst Conference in Prague this week, I was able to get a glimpse using twitter and some blogs. My main focus was on the Life after SOA: Next Generation Application Architecture track. In this post I’ll share some quotes and thoughts with you. SOA Governance On governance I [...]
Sometimes you need another authentication mechanism to verify the username and password. In WLS the default authenticator is file based and can be accessed via a lightweight LDAP interface. For simple straight forward applications, it is sufficient.
In a SOA environment, when you use the default worklist application, the users must be registered in the Weblogic Server. Legacy applications have there own mechanism of storing user data. In our Oracle world, users and passwords are often stored in tables of the database.
The concept of dynamic endpoint selection sounds really neat. At service runtime, the service consumer need not know what service is going to be invoked to fullfill its invocation request; rather, a SOA governance tool can help faciliate this decision of choosing a providing service, based on the pre-defined contractual functionality, interface, SLA, and policy. The SOA governance tool will choose the best service to invoke to accomplish the consumer's requests, bind the consumer to the provider, and complete the "transaction".
Going through yet another one of those "holy crap that infrastructure is expensive" occasions recently I did a quick calculation and found that we could get all of our capacity at an absolute fraction of the internal price. Think less than 1/10th of the quoted price when installation was factored in.What stopped us shifting? Well a little bit of compliance, which we might have overcome, but the
