Oracle Solaris is great due to the fact that it actually is meant for high-end servers.
Oracle Solaris facilitates efficient deployment with its flexible virtualization and strong database handling, excelling in Oracle applications. Users appreciate its incremental backup and resource partitioning features. Renowned for high availability, stability, and cost-effective virtualization that eliminates hypervisor licenses, it optimizes hardware use. Enhancements in scalability, package management, and Oracle's customer service, along with frequent updates, would improve its appeal, addressing issues related to patching and migration downtime.
