A financial services organization planning a typical HCL Workload Automation 10.2 installation for their master domain manager on RHEL 8.4 encounters swap space warnings during the installer pre-checks despite allocating 16GB RAM. The production workload processes 50,000 jobs daily with peak concurrency of 2,500. During typical installation using serverinst, which specific swap space configuration meets both installer requirements and optimal production performance for this workload scale?
Correct Answer: C
HCL Workload Automation 10.2 typical installation via serverinst requires minimum 2GB virtual memory swap space on the filesystem, but production workloads processing 50,000 daily jobs with 2,500 peak concurrency demand 32GB swapfile to handle memory pressure during plan production and job enqueuing spikes without OOM killer intervention. The exact sequence dd if=/dev/zero of=/swapfile bs=1M count=32768; mkswap /swapfile; swapon /swapfile creates properly aligned 32GB swapfile with 1MB blocks optimal for RHEL 8.4 ext4 filesystem, ensuring installer validation passes while providing headroom for symphonia file expansion and netman connection storms. Setting swappiness=10 optimizes usage patterns, but 16GB falls short for peak loads, while zram compression introduces CPU overhead unsuitable for latency-sensitive scheduling.
