the activities of the diagnostic system. With Solaris Fault Manager, the overall
time from a fault condition, to automated diagnosis, to any necessary human
intervention is greatly reduced, increasing application uptime.
• Solaris Service Manager
The Solaris Service Manager facility creates a standardized control mechanism for
application services by turning them into first-class objects that administrators
can observe and manage in a uniform way. These services can then be
automatically restarted if they are accidentally terminated by an administrator, if
they are aborted as the result of a software programming error, or if they are
interrupted by an underlying hardware problem. In addition, the Solaris Service
Manager software reduces system boot time by as much as 75 percent by starting
services in parallel according to their dependencies. An “undo” feature helps
safeguard against human errors by permitting easy change rollback. The Solaris
Service Manager is also simple to deploy; developers can convert most existing
applications to take full advantage of Solaris Service Manager features by simply
adding a simple XML file to each application.
Predictive self healing and fault management provide the following specific capabilities
on Sun SPARC Enterprise T5120/T5220 servers:
• CPU Offlining takes a core or threads offline that has been deemed faulty. Offlined
CPUs are stored in the resource cache and stay offline on reboot unless the processor
has been replaced, in which case the CPU is cleared from the resource cache.
• Memory Page Retirement retires pages of memory that have been marked as faulty.
Pages are stored in the resource cache and stay retired on reboot unless the offending
DIMM has been replaced, in which case affected pages are cleared from the resource
cache.
• I/O Retirement logs errors and faults.
• fmlog logs faults detected by the system.
Solaris CoolTools for SPARC:
Performance and Rapid Time-to-Market
No matter how compelling new hardware or OS platforms may be, organizations must
be assured that the costs and risks of adoption are in line with the rewards. In
particular, organizations want to be able to continue to leverage the considerable
advantages of popular commercial and open source software. Developers don’t want to
have to switch compilers and basic development tools. Administrators can scarcely
afford a more complex support matrix or more time spent getting applications to run
effectively in a new environment. Sun’s CoolTools program is designed specifically to
take the cost and risk out of moving Web tier environments. CoolTools for SPARC are
provided on each Sun SPARC Enterprise T5120 and T5220 server.
