“Making Software Work Together” TM 1 CORBA and Telecoms

“Making Software Work Together” TM 2 CORBA & DOT ready? … hope so!…. it is being successfully deployed

Copyright IONA Technologies 1998 CORBA for Telecoms … a business view..  as a framework for integrating applications in various ways to obtain suites of new systems ….. Add Value to existing Investment  as a tool to make it easier to build distributed software systems ….. Take advantage of distributed resources  as a “technology broker” to help integrate existing & new pieces technology ….. JAVA, ActiveX, Diff. Langs, Complete or Partial Legacy Systems, other technologies

“Making Software Work Together” TM 11 So why do we hear so much about scalability?

Copyright IONA Technologies 1998 … a deployment view... The key to successful Scalability is Manageability

Copyright IONA Technologies … a managed deployment.. Servers Transaction Service Events Service Clients IMS CICS PL/1 COBOL Manager SNMP

Copyright IONA Technologies Early Days... Fault Management Configuration Management Load Balancing etc... Taken care at Application Design stage Minimum ORB vendor support

Copyright IONA Technologies Management Architecture going forward.. Management Enabled Applications Management Enabled Applications SNMP Agent Management Service GUI Tool

Copyright IONA Technologies Architecture-- IDL System programmers can develop “management applications” that interact directly with management servers and management-enabled applications through a set of IDL interfaces.

Copyright IONA Technologies Architecture-- GUI tool Or you can simply use the GUI tool provided Management Enabled Applications Management Enabled Applications Management Service GUI Tool

Copyright IONA Technologies GUI Tools for OrbixManager

Copyright IONA Technologies Architecture-- SNMP SNMP interface allows a System Administrator to manage Applications using standard management platform The Management Server presents an IDL interface to the SNMP Agent

Copyright IONA Technologies The MIB OrbixManager provides an ASN.1 MIB definition which describes the managed objects that can be queried/set... orbixManTableManagement Domains orbixOaTableObject Adaptors orbixSrvTableServersorbixExceptionCORBA Exceptions

Copyright IONA Technologies The Management Service The Management Service is responsible for: Managing exception forwarding Detection of unexpected application termination conditions Persistence and downloading of Managed Applications Properties Interaction with Management Tools and SNMP proxies Quiescing of Managed Servers

Copyright IONA Technologies Management Library Roles and Responsibilities: Monitoring and Reporting of orb activity Location of a Management Service on start up Dynamic topology discovery Exception notification of System and User exceptions Receiving and acting on control signals from the Management Service

“Making Software Work Together” TM Application Management Library ORB library + Management Service Management Service A Management Application Register with the Management Service The Management Service registers the new managed application in the Naming Service

Copyright IONA Technologies Properties Properties-- Name/value pairs used to hold configuration or identification information for processes Management Service provides a persistent service to all Managed objects Can search the management domain for servers/clients with a given property-value
