Overview of AS400 Memory Utilization

Memory utilization on IBM's AS400 (IBM i) systems is critical for maintaining optimal performance. High memory usage can lead to performance bottlenecks, increased response times, and overall inefficiency in operations. Therefore, JTW offers a service that focuses on memory utilization reduction can significantly benefit clients relying on AS400 systems

Key Strategies for Memory Utilization Reduction

  • Monitoring System Resources

    Utilize IBM commands such as WRKACTJOB, WRKSYSACT, and WRKSYSSTS to monitor active jobs and system status. This helps identify jobs consuming excessive memory and CPU resources, allowing for targeted interventions

Identifying and Managing Large Objects

Regularly review and delete unnecessary large objects or files contributing to high memory usage. This can be achieved through systematic audits of stored data and applications

  • Optimizing Job Performance

    Analyze job performance metrics to identify inefficient processes. For instance, jobs that perform high input/output operations can be optimized to use less memory. This may involve modifying queries or adjusting batch job schedules to off-peak hours
