This chapter discusses the preparations and requirements necessary for installing Compaq C for OpenVMS Alpha Systems.
This guide applies to Version 6.2 of Compaq C for OpenVMS Alpha Systems and all subsequent maintenance releases up to the next release of the product that includes an updated installation guide.
Your bill of materials (BOM) and indented bills report (BIL) specify the number and contents of your media. Be sure to verify the contents of your kit with this information. If your kit is damaged or if you find that parts of it are missing, contact your Compaq representative.
Compaq C provides online release notes. Reading the release notes
before proceeding with the installation is strongly recommended. For
information on accessing the online release notes, see Section 2.1,
step 6. The release notes contain installation-related notes and a
summary of technical changes, known problems, restrictions, and
incompatibilities.
1.1 Required Operating System Components
Compaq C Version 6.2 for OpenVMS Alpha Systems requires OpenVMS Alpha Version 6.2 or higher. Future Compaq C releases may require higher versions of the OpenVMS operating system, as described in the online release notes or the Read Before Installing or Using Compaq C Version 6.n for OpenVMS Systems letter.
The OpenVMS operating system comes with a variety of support options, or classes. Classes include such features as networking and RMS journaling. To use Compaq C, your system should be running a version of OpenVMS Alpha that includes the following classes:
For a complete list of the required classes, see the Compaq C
Software Product Description (SPD).
1.2 Optional Software
Table 1-1 provides information on optional software that can be used together with Compaq C.
| Product Name | Description |
|---|---|
| DECset | A comprehensive Computer Aided Software Engineering (CASE) environment consisting of the following integrated components: Language-Sensitive Editor (LSE), Source Code Analyzer (SCA), Performance Coverage Analyzer (PCA), Code Management System (CMS), Module Management System (MMS), and DEC Test Manager. |
Before you install and run Compaq C Version 6.2 on a newly licensed node or cluster, you must first register a License Product Authorization Key (License PAK) using the License Management Facility (LMF). The License PAK may be shipped along with the kit if you ordered the license and media together; otherwise, it is shipped separately to a location based on your license order.
If you are installing Compaq C as an update on a node or cluster already licensed for this software, you have already completed the License PAK registration requirements.
If you are installing prerequisite or optional software along with Compaq C, review the License PAK status and install the License PAKs for any prerequisite or optional software before you install Compaq C.
You must register and load your license for Compaq C before you start the installation in order to run the Installation Verification Procedure (IVP) and use the software.
To register a license under OpenVMS, first log in to the system manager's account, SYSTEM. You then have a choice of two ways to perform the registration:
For complete information on using the LMF, see the VMS License
Management Utility Manual or the online HELP LICENSE utility.
1.4 Installation Procedure Requirements
This section and those that follow discuss various requirements for installing Compaq C.
The installation takes approximately 5 minutes, depending on your type
of media, your system configuration, and the kit components chosen.
1.4.1 Installation Account Privileges and Disk Space
To install Compaq C, you must be logged in to an account that has the SETPRV privilege or at least the following privileges:
VMSINSTAL turns off BYPASS privilege at the start of the installation.
The Compaq C compiler's requirements for free disk storage space are different during installation and after installation. Table 1-2 lists the storage requirements. You can now install the C documentation in .ps, .txt, and .html formats. The installation default is to not install the documentation, but if you do, note the additional disk space required.
| Kit | Blocks During Installation | Blocks After Installation |
|---|---|---|
| Compiler only | 60,000 | 40,000 |
| Compiler and documentation | 140,000 | 90,000 |
To determine the number of free disk blocks on the current system disk, enter the following DCL command:
$ SHOW DEVICE SYS$SYSDEVICE |
Installing Compaq C requires certain system parameter settings.
The minimum number of free global pagelets (512-byte subpage unit) and global sections needed for the installation depends on whether SYS$SYSTEM:DECC$COMPILER.EXE was previously installed as a shared known image:
These values represent the number of free global pagelets and global sections required for the installation, not the total number you need to run your system and other software.
You must ensure that your system has the necessary global pagelets and global section SYSGEN quotas for the installation. Failure to do so could cause the DCL tables to become corrupted in some situations. |
To install and run Compaq C, you must have sufficient free global pagelets and global sections.
Enter the following DCL command to determine the number of global pagelets required by SYS$LIBRARY:DCLTABLES.EXE:
$ DIR/SIZE SYS$LIBRARY:DCLTABLES.EXE |
This command returns the size (in blocks) of SYS$LIBRARY:DCLTABLES.EXE. As an approximation, use this figure as the number of global pagelets needed for the file.
You can use the WRITE command with the F$GETSYI lexical function to find the number of free contiguous global pagelets and free global sections. The following example shows how to get this information at your terminal (the default for SYS$OUTPUT):
$ WRITE SYS$OUTPUT F$GETSYI("CONTIG_GBLPAGES")
15848
$ WRITE SYS$OUTPUT F$GETSYI("FREE_GBLSECTS")
24
|
If the value of free global pagelets or global sections is less than the required value (see Section 1.4.2), you must increase the system parameter setting.
Section 1.4.2.2 describes the procedures for increasing these values using
AUTOGEN.
1.4.2.2 Changing System Parameter Values with AUTOGEN
If you do not have enough free global pages or free global sections to install Compaq C, you can do either of the following:
AUTOGEN automatically adjusts values for parameters that are associated with the values you reset manually. To change system parameters with AUTOGEN, edit the following file:
SYS$SYSTEM:MODPARAMS.DAT |
Use an editor to access the file.
To change a parameter value listed in this file, delete the current value associated with that parameter and enter the new value.
To add a new parameter, add a line to the file that includes both the name of the parameter and its value. For example:
WSMAX = 8096 |
To modify incremental parameters such as GBLPAGES and GBLSECTIONS, use ADD_. The following example increases the global page setting by 2000:
ADD_GBLPAGES = 2000 |
After you make all your changes, exit from the editor, then execute the AUTOGEN procedure to recalculate your system parameters. Enter the following command to recalculate your system parameters and reboot the system:
$ @SYS$UPDATE:AUTOGEN GETDATA REBOOT |
When you specify REBOOT, AUTOGEN does an automatic system shutdown and then reboots the system. Any users logged on to the system are immediately disconnected during the shutdown. The automatic reboot puts the new parameter values into effect.
The AUTOGEN Utility automatically adjusts some of the SYSGEN parameters based on the consumption of resources since the last reboot. If you do not want to take advantage of this automatic adjustment, include the NOFEEDBACK qualifier on the AUTOGEN command line.
For more information about using AUTOGEN, see the OpenVMS System
Management Subkit.
1.4.3 VMSINSTAL and Installation Requirements
When you invoke VMSINSTAL, it checks the following:
If VMSINSTAL detects any problems during the installation, it notifies
you and asks if you want to continue the installation. In some
instances, you can type YES to continue. To stop the installation
process and correct the situation, type NO or press Return. Then
correct the problem and restart the installation.
1.4.3.1 VMSINSTAL Installation Process Requirements
VMSINSTAL requires that the installation account have the following minimum quotas:
ASTLM = 100
BIOLM = 100
DIOLM = 100
ENQLM = 300
FILLM = 300
Use the OpenVMS Authorize Utility to change the process quotas for the installation account in the user authorization file (UAF). (Some sites may restrict the use of the OpenVMS Authorize Utility to certain accounts or people.) For example, to change the BIOLM quota for the account-name installation account, you might enter the following command sequence:
$ RUN SYS$SYSTEM:AUTHORIZE UAF> MODIFY account-name /BIOLM = 100 UAF> SHOW account-name UAF> EXIT $ LOGOUT |
After the quotas for the installation account have been changed, log out of the installation account and log in again for the new quotas to take effect. You can then proceed with the installation.
For more information on modifying account quotas, see the description
of the AUTHORIZE utility in the OpenVMS System Management
Subkit.
1.4.4 Backing Up Your System Disk
At the beginning of the installation, VMSINSTAL asks if you have backed up your system disk. You should do a system disk backup before installing any software.
Use the backup procedures established at your site. For details on performing a system disk backup, see the section on the BACKUP utility in the OpenVMS System Management Subkit.
