DCE Infrastructure DCE Infrastructure Maintenance PlanMaintenance Plan

Robert A. BissellUnixpros, Inc.

Vision StatementVision Statement

Maintain a middleware infrastructure that meets SLA standards and supports the requirements of both production and development environments.

GoalGoal

Improve the middleware infrastructure tools, processes and procedures so that service can be maintained during failures– Hardware devices – Network devices– Software related problems

Set up effective third level support Develop a global support model

TasksTasks

Deploy monitoring and diagnostic tools to identify and correct middleware related problems

Train the second level support team to manage the environment using the diagnostic tool set

Develop procedures for both routine maintenance and failure recovery

Set up third level phone support system

Desired CapabilitiesDesired Capabilities

DCE deployment Proactive maintenance Operational support systems Trend tracking and analysis

Today’s SituationToday’s Situation

DCE/Encina infrastructures is in place in three regions ( North America, Europe, Asia Pacific)

Basic maintenance and recovery procedures are in place

Failures are handled by experts Limited diagnostic tools are available No global support model

Service Level AgreementsService Level Agreements

Middleware– 1 hour maximum time to resolve– 15 minutes mean time to resolve

SLAs exist for both server and service availability

RecommendationsRecommendations

Near term– Intensify third and fourth level support, Set up

phone support) Enhance the current strategy with tools,

procedures and training – Develop and deploy monitoring and diagnostic

tools (compatibility with Tivoli, CA-Unicenter) – Set up a global database of problems/resolutions

RecommendationsRecommendations Employ a proactive maintenance process

– Check for availability and consistency– Perform diagnosis– Perform capacity planning– Perform trend analysis and track changes

Advantages– Increase ability to meet service levels– Exercise greater control over the infrastructure– Decrease reliance on individuals

Proactive MaintenanceProactive Maintenance

Network monitoring at servers Monitor and test services continuously Follow set procedures for each failure

situation Test for cell consistency periodically Track changes in software configuration

Current Monitoring and Current Monitoring and Diagnosis ToolsDiagnosis Tools

Basic DCE monitoring tools are available– CDS ping– dcecp– cell ping– DCE/Sleuth

Current tools are not adequate

Required ToolsRequired Tools
