Chapter 1
Before Installing the Software

DECprint Supervisor runs on OpenVMS Alpha and OpenVMS VAX systems. The files that are installed on the two systems differ. See the Release Notes for a full list of the files.


Starting with DCPS V2.0, the need for DCPS-OPEN and DCPS-PLUS licenses has been eliminated. The right to use all features of DCPS is now included with the OpenVMS operating system license.

1.1 Operating System Version

DCPS V2.1 is fully supported on currently-supported versions of the OpenVMS operating system:

Although DCPS V2.1 will install on systems running OpenVMS Alpha V6.1 or later, or OpenVMS VAX V5.5-2 or later, customers running OpenVMS versions that are not currently supported do so at their own risk.

1.2 Disk Space

Depending on whether DECprint Supervisor is installed on an Alpha or VAX processor, disk space requirements may vary. Table 1-1 lists the disk space requirements.

Table 1-1 Disk Space Requirements
Disk space required for ... Alpha system VAX system
Installation 7400 blocks 5900 blocks
Permanent use 6900 blocks 5500 blocks

These disk space requirements are approximate, and depend on your system environment, disk cluster size, configuration and software options.

1.3 Related Software

DECprint Supervisor works with other software to create a fully functional printing system. Before installing DECprint Supervisor, make sure the other application and printing software is compatible.

The following sections detail the software you need. Refer to the DECprint Supervisor for OpenVMS Software Product Description (SPD) for specific version requirements.

1.3.1 DEC C Run-Time Library

DCPS requires that the DEC C run-time library is installed on your system. This library is included with the OpenVMS operating system starting with OpenVMS V6.1, and in the DEC C/C++ Run-Time Components kit. Therefore:

1.3.2 PrintServer Software

To print to a DIGITAL PrintServer printer, the printing environment must contain a supporting host system running the PrintServer software product.

1.3.3 TCP/IP Networks

TCP/IP connections to PrintServer printers using Common Printer Access Protocol (CPAP), and connections to other printers using the raw TCP/IP socket protocol, require one of the following:

1.3.4 AppleTalk Networks

Printers connected to AppleTalk networks can be accessed by the DECprint Supervisor for OpenVMS software, and thus be made available to OpenVMS system users as shared network printers. This printing system configuration requires PATHWORKS for OpenVMS (Macintosh) software.


PATHWORKS for OpenVMS (Macintosh) has been retired and is no longer supported.

1.3.5 DDIF Printing

To print DDIF encoded bitonal images, DCPS requires that either DECwindows or DECimage Application Services (DAS) be installed on your system. DAS is only available on OpenVMS VAX systems.

1.3.6 DEC Image Print-PLUS (ICPS)

DCPS V1.1 and later versions cannot coexist with ICPS V1.x software. Installing DCPS replaces the image SYS$LIBRARY:TRN$DDIF_IMAGE.EXE. This new image is not compatible with the ICPS software.

1.4 Mismatched Components

All DCPS executable components attempt to ensure they are a matched set. If a mis-match occurs, DCPS reports an error when the queue starts. This error occurs when a component of a prior (incompatible) software version exists in the SYS$SPECIFIC area and newer components are installed in the SYS$COMMON area. The error that occurs depends on which versions of which components are executing. For example:

Chapter 2
Installing the Software

This chapter describes how to install DECprint Supervisor software using the VMSINSTAL utility. If you are not familiar with the VMSINSTAL utility, refer to the OpenVMS System Manager's Manual.

2.1 Overview

Follow these steps to install the DECprint Supervisor (DCPS) for OpenVMS software:

  1. Review all release notes.
  2. Stop each DCPS queue using STOP/QUEUE/NEXT or STOP/QUEUE/RESET if you have existing DCPS queues and do not want the DCPS installation procedure to automatically stop them, or you have DCPS executables in the SYS$SPECIFIC system areas, or you need to apply OpenVMS or other patches that impact DCPS.
  3. Remove any DCPS executables from the SYS$SPECIFIC system areas.
  4. Apply OpenVMS or other patches that impact DCPS, as determined from the DCPS release notes or other sources. If the patches require that you reboot your system, do so after applying the patches.
  5. Install DCPS.
  6. Create or update DCPS$STARTUP.COM, as described in the DECprint Supervisor for OpenVMS System Manager's Guide. For example, add queue definitions to the file and set the value of the DCPS$MAX_STREAMS logical following the examples provided in the procedure.
  7. Start your DCPS print queues by invoking DCPS$STARTUP.COM. The DCPS installation procedure may have restarted DCPS queues that it stopped, if you chose to allow it to do so. If you changed your DCPS environment or DCPS$STARTUP.COM after the DCPS installation procedure automatically restarted some queues, you may need to stop all DCPS queues and restart them before your changes will take effect.

2.2 VMSINSTAL Conventions

VMSINSTAL will prompt you for site-specific information. Questions are preceded by an asterisk (*) and may be followed by default responses enclosed in brackets ([]). Enter your response followed by [Return].

Press [Return] to enter the default response. If you are not sure of the response, enter a question mark (?). VMSINSTAL displays explanatory text and repeats the prompt.

Messages specific to the installation of DECprint Supervisor software are listed in Appendix B.

2.3 Installing the Software


This section does not reproduce all of the text you may see on your screen during the installation of the DECprint Supervisor software. Sample VMSINSTAL installation scripts are shown in Appendix A.

To install the software, use the following procedure:

  1. Invoke the VMSINSTAL procedure.
    Enter the following command:

    $ @SYS$UPDATE:VMSINSTAL DCPSpppnnn device-id [OPTIONS N]

    You supply the following information:

    First, VMSINSTAL displays a banner line with the date and time, and instructions for running the dialog. You may receive one or more of the following warning messages when VMSINSTAL starts up. Exit from the procedure, correct the cause of the warning message, and start the VMSINSTAL procedure again.
    Other processes may cause the installation of HELP to fail. When any of these messages are displayed, the following question is displayed to allow you to terminate VMSINSTAL and correct the situation:

    * Do you want to continue anyway [NO]? 

    Enter YES to continue. If you answer NO, the VMSINSTAL procedure is terminated immediately.
    You can enter a question mark (?) at this time to display advice from the VMSINSTAL software. For example:

    The above conditions may cause VMSINSTAL to function improperly. 
    In particular, problems may occur with file ownership if you are not 
    logged into the SYSTEM account.

  2. Ensure that existing software is saved.
    VMSINSTAL then asks the following question:

    * Are you satisfied with the backup of your system disk [YES]?

    Enter YES to continue, or enter NO to exit VMSINSTAL to make a backup and run VMSINSTAL again.
    If you enter a question mark (?) in response to this question, VMSINSTAL displays the following explanation:

    VMSINSTAL attempts to ensure that a power failure or system crash 
    will not corrupt your system disk.  However, for absolute safety we 
    recommend that you back it up before installing new products.  Please 
    see the documentation for more information on crashes during 

  3. Confirm that distribution media is loaded.
    VMSINSTAL asks for confirmation that the distribution media has been mounted.

     Please mount the first volume of the set on device-id:
    * Are you ready? 

  4. Announce products to be installed.
    VMSINSTAL then announces the products to be installed where ppp designates the platform and n.n designates the version.

    The following products will be processed: 
    DCPSppp Vn.n
            Beginning installation of DCPSppp Vn.n at 13:45 
    %VMSINSTAL-I-RESTORE, Restoring product saveset A

  5. Obtain the release notes.
    If you specified OPTIONS N in the VMSINSTAL command line, the following Release Notes options are displayed:

    Release notes included with this kit are always copied to SYS$HELP. 
    Additional Release Notes Options: 
       Release Notes Options: 
              (1) Display release notes 
              (2) Print release notes 
              (3) Both 1 and 2 
              (4) None of the above 

    After you enter the release note option, VMSINSTAL asks whether you want to continue the installation procedure:

    Do you want to continue the installation [NO]?

    If you did not include the OPTIONS N portion of the VMSINSTAL command line, VMSINSTAL does not display this question. Instead, the following message is displayed:

    %VMSINSTAL-I-RELMOVED, Product's release notes have been moved to SYS$HELP

  6. Check for active DCPS queues.
    If DCPS print queues are active while VMSINSTAL is running, messages similar to the following are displayed:

    %DCPSVAX-W-QUEACTIVE, The following DCPS queues are still active: 
    Queue                     Device                                    Status 
    -----                     ------                                    ------ 
    LN09                      DAN::LTA9000:                             IDLE 
    LN17                      DAN::"AppleTalk/Dan's LN17+ps"            IDLE 
    LN40                      DAN::"IP_RawTCP/ln40:6869"                IDLE 
    LPS32                     DAN::"IP_CPAP/"   IDLE 
    %DCPSVAX-I-NUMQUEUES, 4 existing DCPS queues, with 4 active 
            Previously installed DCPS queues are still running. 
            Continuing this installation without entering 
            STOP/QUEUE/RESET for each such queue can cause 
            inconsistent behavior among queues and can cause 
            the IVP to fail. 
            Note that if you choose to have this installation 
            procedure automatically stop such queues, and the 
            installation subsequently aborts, this procedure 
            will not automatically restart them. 
    * Do you want these queues automatically stopped and restarted [YES]? 

    If you do not want the installation procedure to automatically stop them, you are given the options of aborting the installation or continuing with the queues active. Continuing is not recommended.

  7. Check for sufficient disk space.
    VMSINSTAL checks to see if the amount of disk space required for the installation is available. If the space is not available, a message indicates the amount of disk space that is required, and the installation is aborted. You must allocate sufficient disk space and then start the VMSINSTAL procedure again. However, if you have already provided enough disk space, the installation procedure continues.
  8. Purge extraneous versions of files.
    VMSINSTAL asks if you want to purge any files that are being replaced.

    * Do you want to purge files replaced by this installation [YES]?

    Enter YES if you want to save disk space or NO if you think the files may still be of use.
    If you enter a question mark (?) in response to this query, the following message is displayed:

    During this installation, new files will be provided to replace 
    existing versions.  You may purge these older versions to save disk 
    space, or keep them if you feel they may be of use.  Purging is 

  9. Define DCPS$LAYUP.
    Next, the installation procedure looks for a definition of the logical name DCPS$LAYUP in the system table in executive mode.
  10. Create directories.
    VMSINSTAL then attempts to create several directories. If they already exist, it displays additional messages indicating this:

    %VMSINSTAL-I-SYSDIR, This product creates system disk directory 
    %VMSINSTAL-I-SYSDIR, This product creates system disk directory 
    %VMSINSTAL-I-SYSDIR, This product creates system disk directory 

  11. Make sure the queue manager is running.
    VMSINSTAL checks to see if the queue manager is running on your system.
    If the queue manager is not present, the Installation Verification Procedure (IVP) does not run, and the following messages are displayed on your screen:

    %DCPSppp-I-NOQUEMGR, System queue manager is not running
    -DCPSppp-I-NOQUEMGR, IVP will NOT run.  Installation continuing ... 

    The queue manager must be running if you want the installation to run the IVP.

  12. Stop queues.
    At this point, VMSINSTAL displays the following message on your screen:

    %DCPSppp-I-NOQUEST, No further questions will be asked.

    VMSINSTAL stops active DCPS queues, if any and if desired.

    %DCPSppp-I-STOPQUEUES, Stopping queues previously reported as active. 

  13. Restore the remaining save sets. As it restores each save set, VMSINSTAL reports on its progress:

    VMSINSTAL-I-RESTORE, Restoring product saveset B ...
    VMSINSTAL-I-RESTORE, Restoring product saveset C ...

    This operation may require up to 10 minutes to complete.
    When all the save sets have been restored, VMSINSTAL instructs you to perform postinstallation procedures. Refer to the DECprint Supervisor for OpenVMS System Manager's Guide for full instructions.
    Next, VMSINSTAL moves the files from the temporary locations used during installation to their permanent directories.
