If errors occur during the installation itself or when the Installation Verification Procedure (IVP) is running, VMSINSTAL displays failure messages. If the installation fails, you see the following message:

%VMSINSTAL-E-INSFAIL, The installation of Compaq C V6.n has failed.

If the IVP fails, you see these messages:

The Compaq C V6.n Installation Verification Procedure failed. %VMSINSTAL-E-IVPFAIL, The IVP for Compaq C V6.n has failed.

Errors can occur during the installation if any of the following conditions exist:

• The operating system version is incorrect.
• A prerequisite software version is incorrect.
• Quotas necessary for successful installation are insufficient.
• System parameter values for successful installation are insufficient.
• The OpenVMS help library is currently in use.
• The product license has not been registered and loaded.

For descriptions of the error messages generated by these conditions, see the OpenVMS documentation on system messages, recovery procedures, and OpenVMS software installation. If you are notified that any of these conditions exist, you should take the appropriate action as described in the message. For information on installation requirements, see Section 1.5.

If the installation fails, you must restart the installation procedure from step 2 in Section 2.1. For an explanation of any system messages, see the OpenVMS System Messages and Recovery Procedures Reference Manual or the online HELP/MESSAGE facility. If the installation fails due to an IVP failure, contact a Compaq field service representative.

Compaq C is now installed and can be invoked by all users with the CC command.

The installation procedure modifies the DCL command table so that the CC command is recognized and processed. However, the previous command table is still in effect for those users who are currently logged in. All logged-in users who want to use the CC command must log out and log in again, or use the following DCL command:

$ SET COMMAND /TABLES=SYS$LIBRARY:DCLTABLES

You can perform the following system management tasks after Compaq C is installed:

• Running the Installation Verification Procedure (IVP) separately
• Editing the system startup files
• Making the product usable on an OpenVMS cluster
• Setting user account privileges and quotas
• Enhancing performance
• Reporting problems

The following sections describe these tasks in detail.

3.1 Running the Installation Verification Procedure Separately

You usually run the IVP during installation. If you want to run the IVP separately to ensure the integrity of installed files if system problems should occur, execute the following command procedure:

$ @SYS$TEST:DECC$IVP.COM

If the IVP fails for any reason, the following message is displayed:

Compaq C VERSION 6.n TEST FAILED

3.2 Editing the System Files

You must edit the system startup file to provide for automatic startup of Compaq C when your system is rebooted.

Add the command line that starts Compaq C to the system startup file, SYS$MANAGER:SYSTARTUP_VMS.COM. Compaq C cannot start until after the network has started. You must position this new command line after the line that invokes the network startup command procedure. The following example shows the network startup command line followed by the Compaq C startup command line:

$ @SYS$MANAGER:STARTNET.COM . . . $ @SYS$STARTUP:DECC$STARTUP.COM

3.3 OpenVMS Cluster Considerations

If you want to run Compaq C on multiple nodes of an OpenVMS cluster, first check to see that you have the appropriate software license (see Section 1.4). Then perform the following steps after you install Compaq C:

1. Enter the LICENSE LOAD command, as described in the OpenVMS License Management Utility Manual, to activate the license on each node in the cluster on which Compaq C is to be executed.
2. Log in to the installation node and use the OpenVMS INSTALL Utility to determine whether DECC$COMPILER.EXE is a known image:

   $ INSTALL INSTALL> LIST SYS$SYSTEM:DECC$COMPILER.EXE

   
   If the output of the preceding LIST command shows DECC$COMPILER.EXE to be a known image, perform all of the following steps. Otherwise, perform all of the following steps except step 4b.

3. Log in to a node on the cluster.
4. Run the OpenVMS INSTALL utility as described in Section 3.5.2, with the following exceptions:
   1. After invoking the OpenVMS INSTALL utility, enter the following command:

      INSTALL> REPLACE SYS$LIBRARY:DCLTABLES.EXE

      
      This command updates the DCL tables. It should be entered on each node in the cluster, regardless of whether you activated the Compaq C license (step 1) on all of the nodes.

   2. If DECC$COMPILER.EXE was established as a known image using the INSTALL utility, enter the following command:

      INSTALL> REPLACE SYS$SYSTEM:DECC$COMPILER.EXE

      
      This command replaces the INSTALL entry for DECC$COMPILER.EXE. It should be entered only on those nodes on which you activated the Compaq C license in step 1. (In most cases, all of the nodes will be licensed.)

5. Repeat steps 3 and 4 for each node of the cluster.

Some products cannot be used unless certain privilege and quota requirements are met by user accounts. The following sections describe the privilege and quota requirements needed to work with Compaq C.

3.4.1 User Privileges

To use Compaq C, each account must have TMPMBX and NETMBX privileges. Use the OpenVMS AUTHORIZE utility to determine whether users have the privileges they require.

3.4.2 User Account Quotas

To use Compaq C, a user account does not need to meet any special quota requirements. However, for users who will be compiling very large programs (many program units compiled together), consider adjusting working set (WSDEF, WSQUOTA, WSEXTENT) and pagefile (PGFLQUOTA) account quotas to improve performance.

See Section 1.5.3.2 for a description of how to verify and change account quotas.

3.5 Enhancing Compaq C Performance

The following sections include information on system tuning and explains how to install Compaq C as a shared image.

3.5.1 Tuning Your System

After you install Compaq C, you might want to adjust your system to enhance performance or lower the use of some system resources. General information about tuning an OpenVMS system is included in the Guide to OpenVMS Performance Management.

3.5.2 Installing Compaq C as a Shared Image

If you expect Compaq C to be used extensively on your system, you can reduce the system overhead and memory requirements by installing it as a shared image. To install Compaq C as a shared image on a system that is currently running, use the OpenVMS INSTALL utility. It is recommended that you install Compaq C as shared on a system that has been rebooted recently, because the available space in the global page table is less likely to be fragmented.

To install Compaq C as a shared image:

1. Determine the number of available global pagelets and global sections on your system. You will need to increase them. Section 1.5.2 contains guidelines for showing and setting these parameters.
2. After you have reset the system parameter values, run the following .com file:

   $ $ @SYS$STARTUP:DECC$STARTUP

If you encounter a problem while using Compaq C, see the release notes. If the problem is unresolved, report it to Compaq. Depending on the type of support you have and the nature of the problem, take one of the following actions:

• If you have a Software Product Services Support Agreement, contact your Customer Support Center (CSC) by telephone or by using the electronic means provided with your support agreement (such as DSNlink). The CSC provides telephone support for high-level advisory and remedial assistance. When you initially contact the CSC, indicate the following:
  • The name and version number of the operating system you are using
  • The product name (Compaq C) and the version number of Compaq C you are using
  • The hardware system you are using (such as a model number)
  • A brief description of the problem (one sentence if possible)
  • How critical the problem is
  
  When you submit information electronically or are speaking on the phone to the appropriate Compaq C support specialist, you can provide more detailed information. The information should include the specific commands used to compile and link the program, the error messages displayed, and relevant detailed information (possibly including source program listings). Please attempt to narrow the cause of the problem to a specific module or lines of code.
  CSC personnel might ask for additional information, such as listings of any command files, INCLUDE and COPY files, relevant data files, and so forth. If the program is longer than 50 lines, submit a copy of it electronically or provide machine-readable media (floppy diskette or magnetic tape).
• If the problem is related to Compaq C documentation, you can report the problem to the CSC (if you have a Software Product Services Support Agreement and the problem is severe); otherwise, send your comments about Compaq C documentation to the following Internet address:
  c_docs@compaq.com
  To obtain information about purchasing a Compaq Software Product Services Support Agreement or other support services, please contact your local Compaq sales representative.

This appendix contains sample installations of the Compaq C kit. These are only samples. Sometimes the installation procedure is modified in maintenance updates of this product.

Because this installation guide is not always revised for maintenance updates, be sure to read the Read Before Installing Compaq C for OpenVMS Alpha Systems Version 6.n letter before you install this product. This letter notes any significant changes to the installation samples shown here.

Depending on which layered products you have on your system, you might see additional messages and questions when you perform your installation.

The sample installations assume that DECnet has been shut down, and that no users are logged on to your system. The Installation Verification Procedure (IVP) runs at the end of the installations.
