Solstice Enterprise Manager 4.1 CORBA Gateway Administration Guide

Chapter 1

Introduction

This chapter describes the CORBA Gateway at a high level and introduces the CORBA administration tasks.

This chapter describes the following topics:

• Section 1.1 What is a CORBA Gateway?
• Section 1.2 CORBA Gateway Administration

1.1 What is a CORBA Gateway?

A CORBA Gateway is a set of UNIX processes and shared libraries (see TABLE 1-1) that translate CORBA Manager requests in Interface Definition Language (IDL) to Solstice EM Portable Management Interface (PMI) requests. The CORBA Gateway also translates Solstice EM PMI responses and PMI events to IDL or Internet Inter-ORB Protocol (IIOP) responses and CORBA events.

TABLE 1-1   CORBA Gateway Components 

CORBA Component	Type	Description
Request Gateway	UNIX process	Handles initial CORBA client connections to the CORBA Gateway. It also handles the Common Management Information Server (CMIS) requests/responses regarding managed objects.
Event Gateway	UNIX process	Handles the delivery of CMIS events and notifications to CORBA clients.
Metadata Gateway	UNIX process	Provides CORBA clients with access to ASN1 metadata in Solstice EM.
Event Port Registry	UNIX process	Used by clients to create and register EventPorts, in order to get CMIS events and notifications from the Event Gateway.

The SEM CORBA Gateway product can be deployed to work on industry standard ORBs. The ORB's that are currently supported are VisiBroker 4.5 and Orbacus 4.0.5 and Orbix 2000 1.2.1. The product is delivered as a ToolKit, which lets you build the SEM CORBA Gateway for the required ORB, for more information see Chapter 2.

1.2 CORBA Gateway Administration

CORBA Gateways administration involves the following:

• Basic system administration tasks
  
  
  • Configuring the CORBA Gateway to operate smoothly in your particular environment
    
  • Starting and stopping Gateway processes

  These tasks are described in Chapter 3.

• ToolKit related tasks
  
  
  • Build the Gateways
    
  • Make a runtime package
    
  • Deploy the runtime package on a target machine

  These tasks are described in Chapter 2.

• Troubleshooting tasks

  How to find and resolve errors that affect SEM CORBA Gateway operations. These tasks are described in Chapter 3.

• Performance optimization tasks
  
  
  • Optimizing CORBA Gateway performance
    
  • Optimizing event performance
    
  • Optimizing request/response performance

  These tasks are described in Chapter 4.
