Kıbrıs Guardian API Programming for HPE NonStop Systems Eğitimi

• Concepts and Facilities for NonStop Systems(U4147S) and

• TAL/pTAL Programming (U4198S) or CProgramming in the Guardian Environment (U4143S)

Module 0 - Course Overview

Module 1 - Introduction to the Guardian API

• Major functions of the NonStop operating system

• Components of an executing process

• The required function prototype or declaration file for any Guardian procedure

• The NonStop operating system’s message-based architecture

• Lab: determine the appropriate procedure to use for a given function, identify the parameter types used by specific procedures and if the procedures return a value or set the condition code

Module 2 - File-System Concepts

• Concept of a file, purpose of an I/O process, and different file name types

• Coding the procedure calls that are common to all file accesses

• Using the DEFINE and ASSIGN functions to equate physical and logical file names

• Coding the procedure calls to perform file-name conversion

• Lab: coding Guardian procedures using the DEFINE capability and the Inspect debugger

Module 3 - Interprocess Communication

• Requester-server model

• Coding the procedures for interprocess communication

• Differences between system and application messages

• TACL startup protocol

• Lab: use $RECEIVE for message handling and the INITIALIZER or get_startup_msg to handle the TACL startup protocol messages

Module 4 - Enscribe Database Access

• Enscribe file types and coding the procedures to create Enscribe files

• Coding the procedures to access and manage access of any Enscribe file

• Appropriate error checking

• Lab: access an Enscribe key-sequenced data file

• Lab: code programs to perform Enscribe file accessing including adding, updating, and deleting records.

Module 5 - Terminal Input and Output

• Determining the home terminal of a process

• Procedures used to write to and read from a terminal in conversation mode

• Errors that can occur during I/O

• Numeric conversions from ASCII to binary and vice versa

• Using the FIXSTRING procedure to support command alteration

• Lab: code a program to determine the process home terminal, perform I/O operations from the home terminal, and send application messages to server processes

Module 6 - Timing Facilities

• Coding the procedures to determine the date and time

• Coding the procedures to schedule events for future execution

• Coding the procedures to measure time intervals

Module 7 - Nowait I/O Processing

• Coding the procedures for nowait I/O operations

• One function of the SETMODE procedure

• Internal and external request management

Module 8 - Process Management

• Calling the procedures to start and manage a process

• Calling the PROCESS_GETINFOLIST_ procedure to obtain information about processes

• HIGHPIN and HIGHREQUESTERS object file flags

• Lab: code a procedure to execute a new process

• Lab (optional): modify a given program to perform nowait I/O on selected files

Module 9 - TS/MP Programming

• Major components of the HPE NonStop TS/MP environment

• Pathsend environment and capabilities of a Pathsend requester

• Code calls to the Pathsend procedures

• Code nowait Pathsend operations

• Pathsend error handling

• Design considerations for creating applications using Pathsend

• Design considerations of HPE NonStop TS/MP servers

Module 10 - Data Integrity and Application Availability

• Guardian procedure calls to invoke the HPE NonStop TMF subsystem

• Using HPE NonStop TS/MP subsystem to provide for continuous process availability

• Lab (optional): using Pathsend
