Once, when our team was designing Oozie workflow implementation, the question was raised about how to handle so-called “race conditions”. One of our newly designed workflows had to be run few times simultaneously, and the data, it was working with, had to be consistent. But we noticed that we were getting unexpected results because while first Oozie job was still operating with the data, the other one, which in this case was the same job but started after previous one, tried to operate with same data. Simply speaking, it didn’t wait until previously running one was finished.

It is quite natural to use STB for Scala based projects and at the same time to be compatible with "enterprise-friendly" artifacts repository like Maven Nexus. However what is smoothly and effortlessly done in Maven, can cause a lot of frustration with STB.

Oracle Service Bus is an Enterprise Service Bus playing integral and probably the most important role within SOA platform. One of the core features of an Enterprise Service Bus is a protocol transformation abilites when integrating heterogeneous systems into Enterprise Architecture.
