• Review Cognos logs and diagnose application and platform problems. 

• Configure appropriate Cognos logging and tracing for troubleshooting. 

• Manage log retention and ensure debug or trace logging is disabled when no longer required. 

• Perform Cognos deployment, migration, backup, and recovery activities. 

• Support Cognos upgrades, fix packs, configuration changes, and environment migrations. 

• Test Cognos upgrades for compatibility with custom Java applications, SDK integrations, CJAPs, custom controls, extensions, and other customizations. 

• Maintain appropriate Cognos disaster-recovery and high-availability configurations. 

• Document Cognos architecture, configuration, deployment procedures, and operational processes. 

Performance and Troubleshooting 

• Diagnose complex Cognos performance and availability problems. 

• Distinguish between Cognos application, Java, database, Content Store, network, authentication, operating system, and report-design issues. 

• Analyze Cognos dispatcher and service utilization. 

• Troubleshoot interactive and batch-report execution problems. 

• Investigate long-running reports and scheduled report failures. 

• Analyze Content Store performance and database connectivity. 

• Work with database administrators to troubleshoot SQL performance, locking, blocking, connection, and database issues. 

• Analyze JVM memory, CPU, thread utilization, and application-server behavior. 

• Tune Cognos services, process configuration, and concurrency settings based on measured workload. 

• Troubleshoot SDK application performance and excessive Content Manager or report-service requests.
