The Collaborative Infrastructure provides an environment for hosting distributed software applications and components (actors) that provides a number of services that can be used to simplify management, status monitoring, network transport, messaging, data distribution and translation. The CI is intended to simplify how applications and components can interact with one another shielding them from most of the complications that come with distributed computing involving transport services and directory services and providing a set of general services to monitor and control these applications. The CI provides a set of interfaces and services to enable application developers to easily enable their application to interface with other applications. The CI supports interactions between applications in a highly distributed environment allowing applications to find and/or discover one another and managing the transport of data between applications. The CI application interface design accomplishes this by defining a set of generic interfaces to be used and/or extended by application developers to connect their applications to the collaborative infrastructure. Agent-based architectures have been found to be effective for implementing distributed systems that include components that need to be proactive and operate with some degree of autonomy. Agent-based architectures typically enable cooperation and collaboration among agents by providing a high-level agent communication language and support for sending messages using that language between agents. The CI infrastructure is particularly well suited for hosting agent-based software as it provides for communication among agents using the FIPA standard Agent Communication Language based on Communicative Acts. CI has the following noteworthy features: uses the strengths of CORBA for defining the component interface and for defining data structures transmitted in messages support for both Java and C++ a distributed replicating directory service supporting name-based and capability-based lookups a transport service with pluggable transport protocols (TCP/IP, UDP/IP, SSL (FIPS 140.2 compliant), Multicasting, …) a data distribution service to support publish/subscribe and UDP/IP multicasting while hiding implementation details generic messaging using FIPA Communicative Acts The CI Runtime has an installation program that can be run to install the product. The CI Runtime is supported fully on Windows XP/Vista, Linux, and Mac OS X. Note that the CI Runtime requires ACE/TAO 1.6.9 to develop C++ based CI applications not included as part of the release. The software is currently only available for internal use at NASA. To download the software please send us an e-mail to register@agentisolutions.com providing your name, NASA center affiliation, purpose for the use of the CI, and NASA e-mail address and we will send you a user name and password allowing you to download the software.

		Collaborative Infrastructure Runtime V1.12.7 Windows XP/Vista (16 March 2011): Readme, Installation Instructions, Changes, Build Instructions CI Runtime V1.12.7 (51MB) (includes Oracle JRE 1.6.0_24) Linux (Intel) (tested on Fedora Core 8) (11 March 2011) Readme, Installation Instructions, Changes, Build Instructions CI Runtime V1.12.7 (66MB) (includes Oracle JRE 1.6.0_24) Mac OS X (11 March 2011) Readme, Installation Instructions, Changes, Build Instructions CI Runtime V1.12.7 (17MB) (requires Mac OS 10.4 and JSE 5.0 (1.5.0_06 or later) as the default Java VM) Patches The following patch can be applied to the CI Runtime versions 1.12.1 through 1.12.3 to upgrade it to version 1.12.4. Extract the zip file into the CI installation directory. On OS X make sure to use jar to extract the patch: `cp Patch_CIRuntime_V1_12_4_20100309.zip /Applications/CI cd /Applications/CI jar xvf Patch_CIRuntime_V1_12_4_20100309.zip` Stuffit expander and OS X's copy directory functions wipe out the existing contents of the directory. Patch 9 March 2010 -CI Interface: Optimized how Java Serializable objects are transferred between Java actors within the same Java VM. Before every transfer between actors caused Java Serializable objects to be serialized and deserialized via the transport service. Now introduced a value type that internally manages access to the Java Serializable objects. CORBA ensures that valuetypes are not serialized/deserialized over streams for communication within the same VM, which ensures that the Java Serializable objects do not get serialized/deserialized. The AnyFactory, EnvelopeHelper, PayloadHelper, and DataObjectHelper all use the IJavaObject valuetype to wrap Java Serializable objects. This does of course mean that data structures are shared between actors in the same Java VM. - CI Interface: Fixed issue where if a DDS coordinator was not yet running while other processes relying on the DDS coordinator were started, they would never properly register with the DDS coordinator once the DDS coordinator came up causing amongst one of the things directory service discovery to fail. - CI Hosting Environment: Added support for disabling the shutdown hook by passing the system property: -Dgov.nasa.ci.ahe.disableShutdownHook=true. This feature is required when having the hosting environment started either as a service itself or via a process manager that runs as a service. Without disabling the shutdown hook when logging in/out of Windows the shutdown hook would initiate shutdown of the hosting environment due to it detecting the logout event. - CI Interface: Fixed an issue in the DDS where it did not properly retrieve the retry configuration values. It extracted a String, but values were defined in properties as integers.
