About HP BridgeWorks Version 3.0A Installation Notes for OpenVMS

This Installation Guide comprises system requirements and installation instructions for OpenVMS,  as well as information about running the BridgeWorks Manager and setting process quotas.

For the Windows installation instructions, refer to Readme.htm|pdf|txt, available from the web download page.

For release information, refer to BWX030A.RELEASE_NOTES|.HTM|PDF|PS, available from the web download page and after extracting the kit. (The same release note information is available from the Readme and from the OpenVMS Release Notes.)

Complete product documentation is available from the online Help installed with the Windows BridgeWorks kit.

1.         Platform Requirements

HP BridgeWorks is a cross-platform tool. Installation consists of:

§         An OpenVMS Alpha kit, to be installed on each system on which you intend to run BridgeWorks-wrapped servers.

§         A Windows kit for Windows XP or Windows 2000, to be installed on a development machine, containing the BridgeWorks development tool, plus runtime libraries for distribution if running Windows-based components.

VAX is not a supported platform in this release. BridgeWorks Version 2.1A will continue to be available for wrapping VAX-based applications.

1.1        Targeted Platforms

The purpose of BridgeWorks is to encapsulate and distribute an Alpha-based user application. The server component encapsulates the application; the middle component distributes it. The source code for both components is generated on the Windows platform using a GUI-based development tool.

The generated source code for the server component must be built on the OpenVMS system that hosts the application. The generated source code for the middle component can be built on a networked Alpha system (clustered or not) or a networked Windows system.

Server Component

The BridgeWorks-generated server component is a native OpenVMS image installed on the system running the wrapped application (which can comprise 3GL server routines, ACMS tasks, DCL procedures, and text files.)

Available on OpenVMS Alpha Version 7.3, 7.3-1, and 7.3-2

Note: OpenVMS Industry Standard 64 (Itanium) Version 8.2 and OpenVMS Alpha Version 8.2 are not supported in this release.

Middle Component

The BridgeWorks-generated middle component is a JavaBeans, Enterprise JavaBeans (EJB), or COM server that also acts as a client to the server component to make calls to OpenVMS server routines, tasks, and procedures.

Available platforms for each component type are:

OpenVMS Alpha Version 7.3, 7.3-1, and 7.3-2
Windows XP and 2000


1.2        Generated Components

The middle component can expose the application you are encapsulating, or wrapping, to clients as JavaBeans, EJB, or COM objects. Only the appropriate source code is generated by BridgeWorks.

Specific limitations are shown below according to component type. Note that COM connections cannot be generated for ACMS tasks or for structure or array definitions in 3GL server routines. Note that transactions are only available for EJB components.


Existing Application




3GL, ACMS, DCL, Files




3GL, ACMS, DCL, Files

Not Applicable



3GL, DCL, Files



Not supported in this release:
Tru64 UNIX is not available as a target platform for middle components in this release.

Cross-platform limitations apply to COM:
Cross-platform COM connections - where a Windows client communicates with an Alpha-based middle component - have produced inconclusive results related to account and security issues. The following configurations are recommended instead:

1.       Windows client to Windows COM middle component.

2.       OpenVMS Alpha client to Alpha COM middle component.

Note: Your choice of component architecture should be guided by an understanding of the relative merits and limitations of each component type for your particular distributed application needs. It should take into account any preexisting middle-tier application server and client codebase.

2.       Installation, Development, and Runtime Requirements

These are the minimum system requirements needed to install BridgeWorks and to build and run the generated components. “Optional” requirements represent requirements that are not needed for every type of connection. However, several such requirements will apply to your particular platform/component selection.

Make sure you have the latest MUPs, ECOs, and patches for your configuration. Search for these on the Patch Download page.

Always Check Cross-Product Requirements!
Always check for cross-product software requirements, which can change with new releases. These product requirements may be greater than for BridgeWorks itself.

For example, to run a BridgeWorks-generated EJB component requires OpenVMS Alpha Version 7.3 or higher and a Java 2 Runtime Environment 1.3.1 or higher. Each Java SDK and RTE has specific ECO requirements. In addition, WebLogic Server 7.0 (a J2EE 1.2-compliant application server) requires OpenVMS Alpha Version 7.3 or 7.3-1, the Java 2 SDK 1.3.1-5 or higher, and additional ECOs as specified.

3. Installation

Installation involves setting up HP BridgeWorks on (at least) two systems:

§         Installing the BridgeWorks Manager, development tool utilities, runtime library and support files on OpenVMS.

§         Installing the BridgeWorks development tool, runtime library and support files on Windows.

(For installation instructions for Windows, use Readme.html|pdf|txt, available from the web download page.)

Note: The BridgeWorks Version 3.0A OpenVMS kit can only be used in conjunction with the same Version 3.0A Windows kit. Subsequent production releases will require both installations to be repeated with the up-to-date kits.

3. 1       Installing BridgeWorks on OpenVMS

Version 3.0A installs an enhanced BridgeWorks Manager. This replaces the existing Version 2.1/2.1A Manager, but does not remove it. You can continue to use the 2.1/2.1A Manager process (which is renamed to BWX$MGR_V21) by configuring it to start automatically with 2.1/2.1A connections.

See Section 3.2: Starting the BridgeWorks Manager

The BridgeWorks Manager provides new directory services and server management for the middle component. This includes load-balancing capabilities, such as keeping track of available servers and maintaining pools of free servers (determined by configurable parameters for minimum, maximum, and idle servers) to speed response times. These extra capabilities allow some connections to avoid the high cost of process creation at server startup.

Before you begin:

§         Log into an account that has SYSTEM privileges.

§         If you have a previous version of BridgeWorks installed, make sure the BridgeWorks Manager is shut down by using this command from an account with SYSTEM privileges:


§         Make sure you have adequate disk space. BridgeWorks disk storage requirements are 4,500 blocks during installation and 3,500 blocks after installation.

§         At the beginning of the installation, the installation procedure asks if you have backed up your system. You are recommended to do a system disk backup before proceeding.

Instructions for web download installation

1.       Save the BridgeWorks self-extracting archive (BWX030A_ALPHA.EXE) to a temporary location on your disk by choosing the option to save the program to your disk.  

2.       If you are downloading to a Windows machine, move the downloaded file to your OpenVMS machine using either a shared network drive or FTP.

See Appendix 4.1: Sample FTP File Transfer.

3.       On your OpenVMS system, use the DCL RUN command to unpack the contents of the compressed EXE file:


4.       When you are asked for the file specification of the unpacked file, "Decompress into (file specification):", press Enter/Return for the current directory.

 See Appendix 4.2: Sample OpenVMS Installation Log.

5.       Start PCSI, the utility that installs the BridgeWorks component:


6.       Follow the on-screen installation instructions to complete the installation.

To proceed with a default installation, press Enter/Return in response to any other installation questions.

After Installation:

ALWAYS restart J2EE environments, such as BEA WebLogic Server, or other bean servers, such as Tomcat, after a BridgeWorks installation. Such environments do not automatically refresh shareable  images and libraries without being restarted.

Uninstalling BridgeWorks Version 3.0A

To completely remove BridgeWorks Version 3.0A from your system, perform the following steps:


  1. Stop the BridgeWorks Manager (BWX$MANAGER), and all BridgeWorks generated servers.
  2. Uninstall the BridgeWorks protected sharable image. Bring up the Install utility and use the REMOVE command to remove the SYS$LIBRARY:BWX$COMMON_SS.EXE image.
  3. Enter the PRODUCT REMOVE BRIDGEWORKS command at the DCL command prompt.

Uninstalling BridgeWorks Version 3.0 and earlier

You are not required to uninstall a previous version of BridgeWorks before beginning an installation, and the BridgeWorks kit does not include an uninstall procedure to remove Version 3.0 and earlier versions.  However, if you need to completely remove BridgeWorks Version 3.0 or earlier from your system, perform the following steps:


  1. Stop the BridgeWorks Manager (BWX$MANAGER), and all BridgeWorks generated servers.
  2. Uninstall the BridgeWorks protected sharable image. Bring up the Install utility and use the REMOVE command to remove the SYS$LIBRARY:BWX$COMMON_SS.EXE image.
  3. Delete all files copied onto the system during installation. Refer to the list found in SYS$HELP:BWX$VERSION.TXT for a complete list of these files.

3. 2       Starting the BridgeWorks Manager

After the installation is complete, you must start BridgeWorks Version 3.0A for the first time. This will create directories, define system logicals, and start up the BridgeWorks Manager.

IMPORTANT: Beginning with Version 3.0, BridgeWorks installs an enhanced Manager that is not backward-compatible:

§         The new Manager replaces but does not remove the existing Version 2.0/2.1 Manager.

§         The new Manager uses the same process name, BWX$MANAGER.

§         The 2.1/2.1A Manager is renamed to BWX$MGR_V21.

§         The BWX$MGR_V21 process will continue to be available for existing connections unless you delete BWX$MGR_V21.EXE from SYS$SYSTEM.

  1. Start BridgeWorks for the first time with this command:


  1. Modify your system startup command procedure (SYSTARTUP_VMS.COM) to include the BridgeWorks startup command:


If you are using DCE Transport
You must make sure your TCP/IP and DCE startup procedures run before the BWX$STARTUP.COM in SYSTARTUP.

If you opt not to use the SYSTEM account
The BridgeWorks Manager startup procedure must still be run every time your system starts. It can be run as part of your system startup or in another account that has full access to the BWX$SYSTEM directory.

Important: You are recommended to use the SYSTEM account. However, whatever account you choose to run the Manager out of must have, minimally, the following authorized account privileges:  


*The BridgeWorks Manager requires mailboxes to keep track of when server components become free for new connections. Therefore, LOG_IO privilege is mandatory for both server and manager processes.

See Also Section 3.3: Recommended Process Quotas

Stopping the BridgeWorks Manager

Stopping the BridgeWorks Manager requires the same privileges as starting it. Ensure that all client connections have been closed.

  1. Log into an account that has SYSTEM privileges.
  1. Use the following command:


3.3 Recommended Quotas

Base Requirements

Increase the PRCLM quota to be high enough to run the maximum number of expected concurrent servers.

Java Requirements

The Java runtime environment was designed to perform optimally on UNIX systems, where each process is given large quotas by default. On OpenVMS, the default behavior gives each process lower quotas so that many processes can co-exist on a system.  To get the best Java performance on OpenVMS, you are recommended to set process quotas to match a typical UNIX system. These are also the recommended minimum quota settings (except where noted).

These are the recommended J2SDK for OpenVMS quotas:

UAF Fillm




Wsextent and Wsmax
















*A good number for Pgflquo is (2 x heap-size), for example, 128 MB (2*128*1024*1024)/512 = 524288. Recall that the recommended minimum Pgflquo is 96 MB when using the RTE. When you increase the Pgflquo parameter, you should always increase the system's page file size to accommodate the new Pgflquo parameter, if needed.

There are many other optimizations you can make to your Java environment to improve performance, such as setting the compacting garbage collector with the Fast VM.


This will benefit some but not all Java applications. All such optimizations should be tested in a systematic fashion. You can try out the techniques and tips available from the following source.
