New features of the SolarisTM 9 Operating Environment (Solaris OE) that offer greater availability include a patch manager, modular debugger enhancements and mitigation of buffer overflow areas.

Patch Manager--New in 9--Provides automatic patch inventory and configuration-based analysis of systems, automatic verification of digital patch signatures and automatic resolution of patch dependencies and install order.

Modular Debugger (mdb) Enhancements--New in 9--mdb is now the default system utility for low level debugging and editing of the live operating system in the Solaris 9 OE. It facilitates analyzing operating system crash dumps, user processes, user process core dumps and object files. New features for the Solaris 9 OE include: new symbolic debugging support for the Solaris kernel, new kernel debugger commands, new features for examination and control of live running user processes and the ability to examine raw disk files and devices.

Mitigation of Buffer Overflow Areas--New in 9--Ability to disable execution of code in the stack on a per executable basis. This decreases the risk of exploits due to buffer overflow.

SolarisTM Live Upgrade 2.0 Software--Duplicates the current running boot environment to enable an upgrade. Downtime is reduced significantly. If an upgrade fails, you can fall-back to the original environment with a simple reboot, and eliminate the downtime for the production environment associated with normal test and evaluation processes.

SolarisTM Flash Software--For creating a reference installation of the Solaris OE and application software stack which can then be replicated on several machines. Rapidly provision thousands of complete systems over the LAN or WAN and reduce installation time, configuration complexity and administrative resources, while improving deployment scalability.

Solaris IP Multipathing (IPMP)--IPMP provides the system with recovery from single-point failures with network adapters while increasing traffic throughput.

Reconfiguration Coordination Manager (RCM)--Allows third-party applications to be notified of a DR event so that they can reconfigure or notify the operator that Dynamic Reconfiguration (DR) cannot be performed.

Driver Fault Injection (Driver Hardening Test Harness): Injects a wide range of simulated hardware faults when the driver under development accesses its hardware. This fault injection test harness tests the resilience of a SPARC Delivers higher availability for newly installed systems.
