Systems Administration
Part Two of Network Management Lecture
Elements of IT Infrastrucuture that must be managed
• Enterprise network
• LAN Management
• Server Management
• Desktop Management
• Database Management
• Application Management
• Remote Access Management
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
Server Management & Systems Administration
• Monitoring
• Reporting
• Troubleshooting
• Diagnosing Server performance
• requires Software Modules on Servers
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
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

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
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
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
Database Management
• 2 ways of looking at it: – Distributed Database Management– Enterprise Database Management
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.
Enterprise Database Management
• When companies combine - variety of databases around the enterprise
• Consolidating distributed databases into an enterprise view
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
Laptop Management Technology
• A Mobile MIF is available
• Information gathered:– Battery levels– ac Lines– Docking status– Device bays
