SAFplus 7 Design Specification

• Product Brief

• General Design Requirements

  • This chapter describes general design requirements and rules-of-thumb to ensure a consistent semantic and API style across all services.

• Programming Style Requirements

  • This chapter describes programming style so that SAFplus provides a consistent look.

• Feature Discussion

• Roadmap

Development Tools

• Cluster Design GUI/Integrated Development Environment

• Source Code Structure and Makefile System

• Install and Build

Fundamental Objects

• Handle

  • This is a cluster-wide identifier

  • GlobalHandleT

    • Derives from HandleT, adds a cluster identifier to become globally unique

• Transaction

  • Cross object, node, cluster, transaction

• Checkpoint (AKA Dictionary, map, or hash table)

  • Replicated, nested, persistent, notifiable, shared memory, transactional Hash Table

  • ResourceAssociatedCheckpoint

    • This Dictionary associates a Handle to each key and calls a cleanup whenever the resource represented by the Handle disappears (due to a fault).

• ThreadPool

  • A group of threads that are applied to a list of tasks.

• MessageFlowManager

  • This class intermediates between the messaging layer (send/receive) and the application code. It manages messaging buffers and optimizes frequency of message sending verses message size.

Services

• Logging Applications and other services can log to shared memory. A log server will "scrape" the shared memory and post the message to log channels and/or files.

• Messaging Interface with SAFplus 6.x IOC messaging implementation underneath, but takes a Handle as a destination

• Group Group membership and cluster master election

• Name String name to arbitrary data (generally a Handle)

• Fault All entities report errors to this centralized fault manager. Only it chooses to fault a resource (node or process).

• Availability Management Core process that starts and monitors applications

• Remote Procedure Call Fast and efficient RPC subsystem

• Management Object oriented access to YANG-defined persistent configuration and statistics
