Requirements

The kit you are receiving has been compiled and built using the operating system and product versions listed below. Whilst it is highly likely that you will have no problems installing and using the kit on systems running higher product versions of the products listed, we cannot say for sure that you will be so lucky if your system is running older versions. If you require a kit for a different configuration, we will do what we can to oblige. Note that the UnZip utility is required in order to unpack the ZIP kit.

• HP OpenVMS 8.3 or higher

  It has not been verified whether the kit works with the MultiNet TCP/IP stack, but there is a good chance that it will
• Optional: HP Secure Web Server for OpenVMS (based on Apache) 2.1-1 (if you wish to use the MOD_AMQP Apache module)
• Optional: Web Services Integration Toolkit for HP OpenVMS (WSIT) V2.1 or higher (required if you wish to develop applications using WSIT code generation facilities). Details about WSIT can be found at http://h71000.www7.hp.com/openvms/products/ips/wsit/
• Optional: Java 1.5 or higher (required if you wish to develop Java applications on OpenVMS using WSIT code generation facilities).

RabbitHub Plug-in for PubSubHubBub Released

Overview

RabbitHub is a RabbitMQ plugin-based implementation of PubSubHubBub (a simple web-hook-based pub/sub protocol) that provides an HTTP-based interface to RabbitMQ. It gives every AMQP exchange and queue hosted by the broker two URL’s: one to use for delivering messages to the exchange or queue, and one to use to subscribe to messages forwarded on by the exchange or queue. Subscriptions supply a callback URL to RabbitHub that is used to deliver messages via HTTP POST. While the initial aim of the plugin was support for PubSubHubBub, the plugin provides a generally useful, easy to use, and efficient means of interacting with RabbitMQ in a RESTful manner. When used in combination with other plugins such as those for STOMP, WebSockets, and MQTT, the result is an extremely powerful and flexible messaging solution. Messages may be published via one protocol and consumed by another (or indeed by multiple protocols when messages are published to fanout or topic exchanges).

RabbitHub was originally written by Tony Garnock-Jones (one of the original members of the RabbitMQ team) in 2009; however RabbitMQ has evolved considerably since this time, and it has been necessary to update the code in order for it to work with current RabbitMQ versions. The updated code and 

additional notes can be found at https://github.com/tonyg/rabbithub, and the binary distribution (which also happens to include the sources) can be found here.

The complete installation and user guide may be found here. 

If you would like pre-built kit, please send an email to brett.r.cameron AT gmail.com and johndapps AT gmail.com and we will be happy to oblige.

RabbitMQ 2.8.0 Released for OpenVMS on Integrity Servers

This release of RabbitMQ for OpenVMS is based on the RabbitMQ 2.8.0 distribution. This
release includes a number of bug fixes and adds some valuable new features. Notable new
features include dead lettering (queues can specify an exchange to which messages should
be redirected when they are rejected or expire), and internal flow control to limit memory use
and make performance more predictable if the server is overloaded. Please refer to
http://lists.rabbitmq.com/pipermail/rabbitmq-announce/2012-March/000044.html for details of
these and other new features and improvements included in the 2.8.0 release.

libRabbitMQ V2.1 Released On OpenVMS Alpha and Integrity

libRabbitMQ V2.1 Released On OpenVMS Alpha and Integrity

Introduction
Thank you for your interest in libRabbitMQ for HP OpenVMS. libRabbitMQ provides an API that can be used by OpenVMS-based software applications to exchange data via AMQP (the Advanced Message Queuing Protocol).

The API is primarily intended for use with the RabbitMQ broker (see http://www.rabbitmq.org), but it can in theory be used with any other AMQP broker that fully supports versions 0.8.0 or 0.9.1 of AMQP. libRabbitMQ for HP OpenVMS is based on an experimental C API developed by the RabbitMQ team and has been designed so that it can be used with most programming languages that are available on OpenVMS, including C, FORTRAN, COBOL, and Pascal.Note: It is likely that an updated non-experimental version of the API will become available in the not too distant future. The OpenVMS API will be updated to utilize the new version.

This release of libRabbitMQ for OpenVMS is based on the latest version of the RabbitMQ C-language AMQP client (see http://www.rabbitmq.com/c-client.html), which includes a number of performance enhancements and improved stability. Please see the release notes for detailed information.

This release also includes facilities that allow developers to leverage the code generation and API-level integration capabilities of Web Services Integration Toolkit for HP OpenVMS (WSIT). These facilities include modified WSIT code generation templates for the generation of code that can be used with libRabbitMQ and the RabbitMQ Java client to create powerful, efficient, scalable, and robust integration solutions. The resultant Java code is not constrained to OpenVMS and may be deployed on any platform that supports a suitable JVM.

Please contact brett.r.cameron(at)gmail.com and johndapps(at)gmail.com if you are interested in a kit. Specify whether you need Alpha or Integrity kits.
