Memory Allocation

Although the LANIC card driver does not specifically make class I/O calls, the programs with which the driver interacts generally do. Operations that perform class I/O will require class numbers. The •Memory Allocation" portion of the answer file is where memory is allocated for class numbers.

The amount of system memory necessary for class numbers will vary with subsystem and application requirements. Operating without other active processes, the Node Manager software uses two class numbers.

For applications that access the HP LAN/1000 Link subsystem, additional class numbers are needed. Each program that expects to receive messages from the LAN will require at least one class number. Refer to the appropriate applications manual for class number requirements.

Generate the New System

Now that a new system generation answer file has been created, the system generator program, RTAGN, can be run. In the runstring, the answer file is specified along with other optional parameters. The RTAGN program creates a new system file and snapshot file that are used to install the new system.

For details concerning RTAGN, including file naming conventions, refer to the RTEA System Generation and Installation Manual, part number 92077"90034.

Linking Node Manager Software

The various Node Management software modules must be linked, and ultimately placed in the /PROGRAMS directory.

The Node Manager programs can be linked on the target system or on another system by specifying the target system's snap file.

Depending on whether the target system is intended for a disk"based or memory"based computer, installing the new system will vary slightly. Consult the RTEA System Generation and Installation Manual, part number 92077"90034, for complete details.

Security/1000

If the Security/1000 system is installed on the operating system, the Node Manager link command files (indicated by •.LOD") may be altered to provide the level of program capability desired by the system manager. The default Node Manager link command files presume the same level of security as though Security/1000 is not installed. For more information on the Security/1000 system and program security levels, see the RTEA System Manager's Manual, part number 92077"90056.
