Glossary Terms

DTrace: DTrace is a comprehensive dynamic tracing feature built into the Solaris OS. DTrace lets administrators and developers examine the behavior of user programs and the operating system itself on live production systems. DTrace allows users to explore systems to understand how they work; track down performance problems across multiple software layers; and locate causes of aberrant behavior.

ZFS (Zettabyte File System): Solaris ZFS represents a dramatic advance in file system management and maintenance. ZFS automates many common administrative tasks, protects data from corruption, and provides virtually unlimited scalability. ZFS reduces administrative overhead by up to 80 percent, provides 99.99999999999999999 percent error detection and correction, and offers 16 billion times the capacity of 32- or 64-bit file systems.

Solaris Containers: The Solaris Containers feature enables isolation of individual software applications and services using flexible, software-defined boundaries. Solaris Containers provide administrators with the ability to define and meet service levels by dynamically controlling application and resource priorities. Each application can be given its own private environment, virtually eliminating error propagation, unauthorized access, and unintentional intrusions.

PSH (Predictive Self-Healing): Predictive Self-Healing is an innovative technology that automatically diagnoses, isolates, and recovers from many hardware and application faults. PSH allows business-critical applications and essential system services to continue uninterrupted in the event of software failures, major hardware component failures, and software configuration problems.

RBAC (Role-Based Access Control): Role-based access control is an alternative to the traditional superuser model of root access to UNIX systems. RBAC allows administrators to assign rights to individual, trusted users and perform specific operations, including access to resources such as serial port, file, log, printer management, user login control, and system shutdown. Users are authenticated before any role is assumed so that all privileged activities can be logged and associated with specific users.

IPSec (Internet Protocol Security): IPSec is a suite of security protocols, providing privacy and authentication services at the Internet Protocol (IP) layer.
