Running Tomcat on OpenVMS
HP offers an Apache based web server named "Secure Web Server" (SWS). It includes an Apache module CSWS_JAVA (Tomcat). The current version of this module is CSWS_JAVA Version 7.0-29 for OpenVMS Integrity Server (based on Apache Tomcat 7.0.29).
At the time of writing, it is unknown to me whether HP plans to create newer versions of Tomcat for SWS.
These notes show how to install and run Tomcat on OpenVMS, independent of HP's Secure Web Server.
I hope these notes are of use to someone out there.
THE ENVIRONMENT
OpenVMS for Integrity Servers Version 8.3 is the minimum version for which this should work. Newer versions are recommended, as there are 8.3-1H1 or 8.4 from HP or 8.4-1H1 from VSI.
Java 6 (at the time of writing there is no newer Java version available from HP or VSI), the HP kit is named J2SE™ Development Kit (JDK) 6.0-4, which is based on Java SE 6 Update 37.
Patches, aka ECOs, for OpenVMS as listed in http://h18012.www1.hp.com/java/download/ivms/1.6.0/jdk6.0_patches.html.
Some disk space (~20MB is the minimum for the installation) on an ODS5 disk.
A recent archive tool for zip archives or compressed tar files.
Scripts, aka VMS DCL command procedures, as shown below.
THE INSTALLATION
Ensure that Java 6 is installed on OpenVMS and that at least all the ECOs as described above are installed. It is recommended to have the operating system patched to the current level. At least the C-run-time environment should have the current patch level.
Step 1: Download Tomcat
Download Tomcat from the Tomcat home page, and get the binary version, either the zip or tar.gz file. I downloaded apache-tomcat-7.0.64.tar.gz.
Step 2: Extract Tomcat archive
Extract the files into a directory on an ODS5 disk. Verify that your unzip or tar utility creates case sensitive file names. The result of extracting will be a sub-directory apache-tomcat-7.0.64, which from the VMS command line will be shown as apache-tomcat-7^.0^.64.DIR;1 (For convenience you can rename the directory file, to avoid the escape character '^', for example to apache-tomcat-7064.DIR;1.)
It is recommended to use the directory filename as is and to set the VMS process' parse style for commands to accept ODS5 file specifications: $ set process/parse_style=extended/case_lookup=blind.
It is also recommended to make the sub-directory files deletable: $ set protection=o:rwed [.apache-tomcat-7^.0^.64...]*.dir
Step 2: Add the OpenVMS specific scripts
Extract the scripts shown below into the appropriate directories.
Step 3: Test the installation
Run the version script: $ @[.apache-tomcat-7^.0^.64.bin]version. The result should look like:
Server version: Apache Tomcat/7.0.64 Server built: Aug 19 2015 17:18:06 UTC Server number: 7.0.64.0 OS Name: OpenVMS OS Version: V8.4 Architecture: ia64 JVM Version: 1.6.0-6 JVM Vendor: Hewlett-Packard Company $
Start Tomcat: @[.apache-tomcat-7^.0^.64.bin]startup.
The supplied startup script runs Tomcat in a spawned OpenVMS sub-process of your current interactive process. That is, there will be some asynchronous output shown in your terminal which is produced by VMS and/or Tomcat. However, you can enter any DCL command while Tomcat is running - including the command to stop it.
The output may look like:
%DCL-S-SPAWNED, process BECKER_39053 spawned $ Oct 16, 2015 2:56:17 PM org.apache.catalina.startup.VersionLoggerListener log INFO: Server version: Apache Tomcat/7.0.64 Oct 16, 2015 2:56:17 PM org.apache.catalina.startup.VersionLoggerListener log INFO: Server built: Aug 19 2015 17:18:06 UTC Oct 16, 2015 2:56:17 PM org.apache.catalina.startup.VersionLoggerListener log INFO: Server number: 7.0.64.0 ... Oct 16, 2015 2:56:26 PM org.apache.catalina.startup.Catalina start INFO: Server startup in 8339 ms
Now open a browser window, and enter http://YOUR_VMS_NODE:8080 - the default Tomcat page should open.
Stop Tomcat: @[.apache-tomcat-7^.0^.64.bin]shutdown.
Similar to the startup script, the supplied shutdown script runs in a spawned OpenVMS sub-process. That is, there will be some asynchronous output shown in your terminal which is produced by VMS and/or Tomcat. However you can enter any DCL command while Tomcat is shutting down.
The output may look like:
%DCL-S-SPAWNED, process BECKER_18865 spawned $ Oct 16, 2015 3:00:50 PM org.apache.catalina.core.StandardServer await INFO: A valid shutdown command was received via the shutdown port. Stopping the Server instance. ...
Step 4: After the installation
Now you are ready to deploy your web application and configure Tomcat for your needs.
Whether you remove specific files, which are not required for OpenVMS is up to you as well as removing the default Tomcat web application.
