Installing CA Gen on NonStop › Installation Prerequisites

Installation Prerequisites

Before installing the CA Gen Implementation Toolset (IT) for NonStop, complete the following tasks:

• Confirm the NonStop server meets the hardware and software requirements for installing CA Gen. See the CA Gen Release 8.5 Technical Requirements document.
• Note the location of configuration files that contain site-specific customizations for running the IT at your site. You can customize the configuration files after IT installation.
• Consider file security and file ownership requirements when selecting a location to install the IT. Each NonStop system is managed differently and file system access may be based on the location of files, the file security vector, the logged in group and user ID, or a combination of these attributes. If you are not the system administrator for the NonStop server on which you are installing the IT, consult the system administrator for information about applicable security and access details.
• The installation procedure lets you set site-wide Pathway and compiler settings. When set, the Setup Tool can use these settings during CA Gen application installation on NonStop. Review the configuration parameters for Pathway and for the compilers with your system administrator. Consider the operation of the generated applications to be built when determining if changes are required. An experienced NonStop system administrator address changes to the configurations of Pathway and compilers on the NonStop server.
• To report build-time events, you can incorporate the optional Event Management Subsystem (EMS) templates for the Setup Tool into the EMS templates for the NonStop operating system. The EMS templates enhance Setup Tool application troubleshooting. Run the INSTTMPL macro as user SUPER.SUPER to make this change to the NonStop system configuration.

  Regardless of whether the EMS templates are installed, to ensure that the built-in EMS viewer in the Setup Tool can correctly display EMS messages, the security vector for the collector's log files must allow network read access.  Failure to correctly set security settings result in a security violation error (Error 48). The collector's log files are usually in the $SYSTEM.ZLOGxx subvolume,  where xx is the current OSIMAGE identifier.

• Use caution when partially reinstalling the IT after the initial installation. Review the existing targets that need configuration data that is preserved to avoid accidentally deleting data. For example, if you Select the Create Setup Tool Database option on the Setup Tool Install Menu, you lose existing target configuration data for that instance of the Setup Tool.
• Consult the NonStop system administrator to determine the maximum number of simultaneous installations and the maximum number of compilations the Setup Tool can run simultaneously. The combination of these two factors can substantially impact the system performance. IT installation macros include options for setting these values. These values can also be set after installing the Setup Tool. Doing so requires knowledge on how to modify Pathway configuration files.
