Subject: JOnAS for OpenVMS

JOnAS is a J2EE applications server. It is developed under the guidance
of the ObjectWeb consortium (http://jonas.objectweb.org).

Jean-Yves Bourles and I have ported JOnAS 4.3.4 on OpenVMS. This
release is Sun J2EE 1.4 certified. Porting means testing all the
functions, writing startup, shutdown and admin procedures and creating
a PCSI kit.

JOnAS is a free software under an LGPL license. JOnAS for OpenVMS needs
Java 1.4.1-2 or later. It MUST be installed on ODS5 volume. JOnAS has
been tested on Alpha but not yet on Itanium.

The PCSI kit (70 Mo) is based on the official archive
jonas4.3.4-jetty5.1.2.tgz and can be downloaded at :

The kit has been tested only on a few sites. Remarks and appreciations
are welcome.

Some performance consideration :

1. During the first startup, JOnAS deploys its applications in a
directory called work. 127 subdirectories and 1333 files are created
during this deployment. It takes a lonnnnng time (7 minutes on my
AXP900 workstation) on OpenVMS (the usual RMS bottleneck with Java...).
This work directory is persistent. So the following startups are faster
(1 minute on my AXP900 workstation).

2. The files created on-the-fly by the applications (jsp
compilation...) are put in sy$scratch. I redirect sys$scratch towards a
directory called scratch under the JOnAS root directory in the startup
procedure. If you have DECram, redirecting sys$scratch towards a
RAMdisk greatly improves the response time.
