The Open MQ team has been busy preparing the initial promoted builds of their upcoming new minor feature release, Open MQ 4.4. It's impressive that without any real prodding from our Update Center Toolkit team, the MQ team has pretty much of their own accord begun adopting pkg(5) and the Update Center Toolkit as the main delivery format for this next release. The MQ team has produced a series of installer wrapped download bundles containing pre-installed pkg(5) images for their supported platforms and they are in the process of delivering a companion set of raw zip downloads using virtually the same underlying pre-installed pkg(5) images. You can obtain their preliminary promoted builds of the installer-wrapped bundles from their MQ 4.4 release site.
Shape of the pkg(5)-based Open MQ Distribution
The Open MQ 4.4 builds currently consists of at least 9 pkg(5) packages containing content ranging from portable Java components of the core product to platform-specific components such as the optional C language client API. Platforms addressed by these preliminary builds include: Windows, Linux, Mac OS X, Solaris and OpenSolaris. Once AIX is supported by the Update Center project's port of the pkg(5) system in v2.3 of the toolkit, the Open MQ AIX bundle will likely migrate to using pkg(5) packages of their AIX install bundles.
Benefits of Sustainable, Modular Binary Packages
In addition to forming the basis of the MQ 4.4 distribution, these same pkg(5) packages are integrated into builds of the GlassFish v3 distribution. Thereby demonstrating the value of reusing the same modular binary packages across multiple product distributions. Historically, the lack of formal packaging of raw zip and tar.gz bundles has made it difficult for development and sustaining teams to deliver and share the same updated binaries. With the adoption of the pkg(5) system and the Update Center Toolkit, development and sustaining teams only need to deliver one set of updated packages that can be shared across multiple product distributions.
