The document discusses various elements of IT infrastructure that require management, including enterprise networks, servers, desktops, databases, and applications. It describes several standards and technologies used for managing these elements, such as SNMP, WBEM, DMI, and application response measurement. It also covers challenges around managing distributed and laptop/mobile environments.

1. Systems Administration Part Two of Network Management Lecture

2. Elements of IT Infrastrucuture that must be managed Enterprise network LAN Management Server Management Desktop Management Database Management Application Management Remote Access Management

3. Application Management Specification AMS: put together by HP, Tivoli, Oracle ARM: Application Response Management Also IETF standard WBEM : Web Based Enterprise Management Integrates SNMP & HTTP & DMI

4. Server Management & Systems Administration Monitoring Reporting Troubleshooting Diagnosing Server performance requires Software Modules on Servers

5. Configuration Management Single Sign-on Licence metering tools Automated S/W inventory tools Software distribution tools Handled by Policy Based Management tools Can manage more than one type of Computer

6. Client & Desktop Management Config & support of Workstations or Clients Hardware & OS more than Apps Architecture & Protocols proposed by “ Desktop Management Taskforce” (DMTF) Gives rise to DMI

7. Distributed Management Architecture An API that can be used by applications developers is known as application response measurement (ARM) and can measure several key application statistics

8. Client & Desktop Management In theory - Desktop Management & Enterprise Management must be able to interoperate Desktop Mgmt info stored in MIF ( Management Info Format ) Enterprise uses a MIB ( Management Info Base ) MIB - MIF mapper required

9. Desktop Management Technology Suites of Applications Netwizard Tivoli IT Director Challenge is extending desktop management to Laptops S/Wdistribution, change analysis, job scheduling, asset monitoring, backup, virus protection

10. Database Management 2 ways of looking at it: Distributed Database Management Enterprise Database Management

11. Distributed Database Management Build in self diagnosing intelligence referred to as ‘Instrumentation’ Software Agents that collect performance data and report it via SNMP 2 network related variables that can affect this are: Bandwidth & Latency No standard of what data should be gathered or how it should be reported.

12. Enterprise Database Management When companies combine - variety of databases around the enterprise Consolidating distributed databases into an enterprise view

13. Enterprise Database Management Tools Global User Administration Security Management Heterogeneous data schema and content manipulation Effective troubleshooting Monitor for free space, runaway processes,high CPU utilisation, low swap space Should support: Oracle, Informix, SQL Server, Adaptive Server & DB2

14. Laptop Management Technology A Mobile MIF is available Information gathered: Battery levels ac Lines Docking status Device bays
