2.6.1 Checking System Parameter Values

To check the values of your system parameters, enter the following command at the DCL prompt to invoke SYSGEN:


At the SYSGEN> prompt, enter the SHOW command to display the value of each system parameter. Make sure that the values displayed equal or exceed the value of each parameter listed in Table 2-6 or Table 2-7. The following command displays the value for the VIRTUALPAGECNT system parameter:

Parameter Name       Current   Default    Min.    Max.   Unit  Dynamic
--------------       -------   -------   ------  ------  ----  -------
VIRTUALPAGECNT        270144      9216    512    1200000 Pages

This example shows that the current value for VIRTUALPAGECNT is 270144.

After you finish checking the parameters with the SHOW command, enter the EXIT command at the SYSGEN> prompt to return to DCL level.

2.6.2 Calculating the Values for GBLPAGES and GBLSECTIONS

To install and run ACMS, you must set the correct values for the GBLPAGES and GBLSECTIONS system parameters.

The values for GBLPAGES and GBLSECTIONS in Table 2-6 and Table 2-7 (excluding the value of n) indicate the number of unused pages or sections you must have available on your system for the installation to process successfully. To calculate whether your system has a sufficient number of unused global pages and global sections, perform the following steps:

  1. Show the current free global pages and global sections using the following DCL commands:


  2. Determine if the number of unused pages (3420 in the example) is equal to or greater than the number specified in Table 2-6 or Table 2-7. If the number of unused pages is less than the number listed in the table, increase the allocation value for GBLPAGES.
  3. Determine if the number of unused global sections (72 in the example) is equal to or greater than the number specified in Table 2-6 or Table 2-7. If the value is less than the number required, increase the allocation value of the GBLSECTIONS parameter.

Section 2.6.3 describes the procedures for increasing these values as well as those of other system parameters. Refer to the OpenVMS documentation on system management and operations for more information.

2.6.3 Changing System Parameter Values with AUTOGEN

Use the AUTOGEN command procedure to change system parameters. To change system parameters with AUTOGEN, you must edit the following file:


For example, to change the setting for the GBLPAGES system parameter, add this line to the file:

GBLPAGES = 100000 

Now, run the AUTOGEN procedure to recalculate your system parameters. Enter the following command at the DCL prompt:


For more information about using AUTOGEN, see the instructions on modifying system parameters in the OpenVMS documentation on system management and operations.

2.6.4 Setting the CLISYMTBL Dynamic System Parameter

If the CLISYMTBL system parameter value for your system is less than 500, change the setting by entering the following series of commands:


CLISYMTBL is a dynamic parameter, which means that you do not have to reboot the system to make the change take effect. The new value for CLISYMTBL becomes effective when you enter the SYSGEN command WRITE ACTIVE.

If you do nothing further, the new value for CLISYMTBL remains in effect until the next time you reboot the system, at which time the old value for CLISYMTBL is restored.

If you want to make the new CLISYMTBL value permanent, enter the following SYSGEN command:


The WRITE CURRENT command writes the new value for CLISYMTBL into the SYSGEN database on disk, so that it is available when the system is rebooted.

To exit from SYSGEN, enter the following command:



If you changed the value of CLISYMTBL, log out and log back in so that the new value can take effect.

2.7 Process Account Quotas

The account you use to install ACMS must have sufficient quotas to enable you to perform the installation. Table 2-8 summarizes the process quotas required to perform the installation.

Table 2-8 Process Account Quotas
Account Quota Required Value
BYTLM 32,768
ENQLM 2,000
PGFLQUO 12,800

User account quotas are stored in the file SYSUAF.DAT. Use the OpenVMS Authorize Utility (AUTHORIZE) to verify and change user account quotas. First set your directory to SYS$SYSTEM and then run AUTHORIZE:


At the AUTHORIZE prompt (UAF>), enter the SHOW command with an account name to check a particular account. For example:


To change a quota, enter the MODIFY command at the UAF> prompt. MODIFY has the following format:

MODIFY account-name/quota-name=nnnn

The following example changes the FILLM quota for the SYSTEM account and then exits from the Authorize Utility:


After you exit from the utility, the OpenVMS system displays messages indicating whether or not changes were made. Once the changes have been made, you must log out and log in again for the new quotas to take effect.

For more information on modifying account quotas, see the description of the Authorize Utility in the OpenVMS documentation on system management and operations.

2.8 Time Required for Installation

Table 2-9 lists the approximate time required for installing each ACMS kit.


Installation time depends heavily on installation options, system load, hardware, and kit media. The times listed in Table 2-9 were measured for full installations on a standalone DEC 3000 (Alpha) system with disk-resident kits. Your time may vary.

Table 2-9 Timetable for Installing ACMS
Kit Installation Time1 IVP Time
Development 7 minutes 2 minutes
Run-time 4 minutes 2 minutes
Remote-access 2 minutes 1 minute

1If you are using the VMSINSTAL option AWD, multiply these times by 3.

2.9 ACMS$IVP User Authorization

The ACMS installation checks for the presence of the OpenVMS user account ACMS$IVP. If this account does not exist, you are asked for information needed to create it. The ACMS$IVP account is used to run the ACMS Installation Verification Procedure.

Among the information requested for this account is a unique user identification code (UIC) in the form [ggggg,nnnnnn], where ggggg is an octal user group number in the range 1--37776, and nnnnnn is an octal user number in the range 1--177776. Additionally, the group number cannot be a system group number.

Enter the following commands to list the UICs currently in use on your system:


The result of these commands is that all UICs in use on your system are listed in the file SYSUAF.LIS, in your default directory. You can then examine this listing to determine a unique UIC for the ACMS$IVP account.

On your system, a certain range of group numbers has been reserved for system users. To determine this range, execute the following commands:


The value you supply for the octal group number in the ACMS$IVP UIC must be greater than the octal value of the symbol MAXSYS. The following example shows that the maximum system group number is octal 10; therefore, you must specify a group number for the ACMS$IVP UIC that is in the range 11--37776:

  MAXSYS = 8   Hex = 00000008   Octal = 00000000010

Chapter 3
Installing ACMS

This chapter describes how to install the ACMS software. Section 3.2 contains a step-by-step description of the installation procedure.

3.1 Installation Log

A log of your installation is kept in the following file:


In particular, if the ACMS installation fails because prerequisites were not met, this log contains a list of those prerequisites. You can use it as a check list of items to address before you reinstall ACMS.

In addition, after the installation is completed, a list of the files created by the installation is stored in the following file:


3.2 Installation Procedure

ACMS provides online release notes. The prompt to display or print the release notes before the installation appears in the installation procedure, if you invoke VMSINSTAL with the OPTIONS N parameter. For information on accessing the release notes after the installation, refer to Section 3.4.

The ACMS installation process is divided into five phases:

To abort the installation procedure at any time, press [Ctrl/Y]. When you press [Ctrl/Y], the installation procedure deletes all files it has created up to that point and exits. You can then start the installation again.

3.2.1 Invoking VMSINSTAL (First Phase)

To start the installation, log in to the SYSTEM account, and set default to the SYS$UPDATE directory:

Username: SYSTEM   

Next, invoke VMSINSTAL. Use the following syntax to invoke VMSINSTAL:

@VMSINSTAL product-name device-name [OPTIONS option-1[,...]]


The installation name for the component. Enter one of the following:


The name of the device on which you plan to mount the media. For example, CDROM is the device name for a tape drive.


An optional parameter indicating that one or more VMSINSTAL options are being supplied. This parameter is followed by a space, and then the requested options. If multiple options are requested, separate them with commas (,); do not include spaces in the options list.

The following are VMSINSTAL options that you can use for the ACMS installation:

VMSINSTAL has several other options; for information, see the OpenVMS documentation on software installation.


ACMS does not support option R, the alternate root option.

On Alpha, the following command invokes VMSINSTAL and installs ACMS from the CD-ROM reader. This example uses the N option for printing or displaying release notes, and the AWD option to use disk DISK1 as an alternate working device:

      OpenVMS AXP Software Product Installation Procedure V7.3
It is 22-JUN-2001 at 11:00.  
Enter a question mark (?) at any time for help.

If you do not supply either the product name or the device name, VMSINSTAL prompts you for this information later on in the installation procedure.

  1. System backup VMSINSTAL asks the following question to ensure that your system disk is properly backed up:

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

    Always back up your system disk before performing an installation. If you are satisfied with the backup of your system disk, press [Return]. Otherwise, answer NO to stop the installation. After you back up your system disk, you can restart the installation.

  2. Mounting the media VMSINSTAL instructs you to mount the ACMS Version 4.4 distribution media on the device you specified when you invoked VMSINSTAL. When you have mounted the media, answer YES to the question, "Are you ready?":

    Please mount the first volume of the set on CDROM.
    * Are you ready? Y

    If you entered the wrong device name when you invoked VMSINSTAL and need to restart the installation, answer NO in response to the question. To abort the installation for any other reason, press [Ctrl/Y].
    VMSINSTAL then reads the media and begins the installation of ACMS. A message similar to the following appears:

    The following products will be processed:
      ACMSDEVA_ V4.4
            Beginning installation of ACMSDEVA_ V4.4 at 11:01
    %VMSINSTAL-I-RESTORE, Restoring product saveset A...

  3. Release notes If you specified OPTIONS N when you invoked VMSINSTAL, you are now given several options for reviewing the release notes.

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

    If you select option 1, VMSINSTAL displays the release notes immediately. You can terminate the display at any time by pressing [Ctrl/C]. Because the release notes are lengthy, it is recommended that you choose option 2 to print the release notes rather than reviewing them on line.
    If you select option 2, VMSINSTAL prompts you for the name of the print queue that you want to use:

    * Queue name [SYS$PRINT]: 

    You can enter a queue name or just press [Return] to send the file to the default output print queue SYS$PRINT.
    If you select option 3, VMSINSTAL displays the release notes immediately and then prompts you for a queue name for the printed version.
    If you select option 4, VMSINSTAL does not display or print the release notes. Use the DCL command TYPE or PRINT to view the release notes in the following file:


    The release notes are copied to the SYS$HELP directory under all circumstances, regardless of your choice from the menu.


    The release notes for each version of ACMS are uniquely named so that release notes from multiple versions can be maintained. To facilitate comparison of various versions of ACMS, Compaq recommends not deleting release notes for previous versions of ACMS.
  4. Continuing the installation The installation procedure now asks if you want to continue the installation. To continue, answer YES. Otherwise, press [Return] to stop the installation:

    * Do you want to continue the installation [N]?: Y
    %VMSINSTAL-I-RELMOVED, Product's release notes have been moved to

    After you read the release notes, you can restart the installation without being questioned about the release notes by removing OPTIONS N from the VMSINSTAL command. For example:
