“…1, an interesting aspect being that they are backed by occurrences in enterprise software observed by our industrial partners. We note here that as with related abstractions developed in earlier work [14,20,28], the changes made by isolation points occur at the middleware level and can be realized and carried out without requiring modifications to application code.…”

Abstract. A problem with many distributed applications is their behavior in lieu of unpredictable variations in user request volumes or in available resources. This paper explores a performance isolation-based approach to creating robust distributed applications. For each application, the approach is to (1) understand the performance dependencies that pervade it and then (2) provide mechanisms for imposing constraints on the possible 'spread' of such dependencies through the application. Concrete results are attained for J2EE middleware, for which we identify sample performance dependencies: in the application layer during request execution and in the middleware layer during request de-fragmentation and during return parameter marshalling. Isolation points are the novel software abstraction used to capture performance dependencies and represent solutions for dealing with them, and they are used to create (2) I(solation)-RMI, which is a version of RMI-IIOP implemented in the WebSphere service infrastructure enhanced with isolation points. Initial results show the approach's ability to detect and filter ill-behaving messages that can cause an up to a 85% drop in performance for the Trade3 benchmark, and to eliminate up to a 56% drop in performance due to misbehaving clients.

Current mappings of IDL to implementation languages such as C++ or Java use CORBA specific data-types, which makes it imperative for an object implementation to be CORBA-compliant. While being completely CORBA-compliant ensures portability and interoperability, several classes of enterprise applications may only require interoperability with other CORBA applications. Other applications may be constrained by such factors as a large existing code-base or a widely used communication protocol. In many cases, these applications can benefit from the concise expressiveness of IDL without committing to the overhead of using a general-purpose CORBA ORB. To aid this process, we propose a new approach to ORB design where the IDL mapping and ORB protocol is completely configurable. As a motivation, we present our use of IDL in the development of a large in-house application. In this application, all interfaces are specified using IDL, which is mapped to C++ using a custom mapping. We then present an architecture for a template-driven IDL compiler and describe the implementation of a prototype we built. With this compiler architecture, an IDL mapping can easily be specified and customized by writing an appropriate template.
