|Oracle Solaris Tunable Parameters Reference Manual Oracle Solaris 11 Information Library|
Several tools are available to examine system configuration information. Some tools require superuser privilege. Other tools can be run by a non-privileged user. Every structure and data item can be examined with the kernel debugger by using mdb on a running system or by booting under kmdb.
The sysdef command provides the values of memory and process resource limits, and portions of the tune and v structures. For example, the sysdef “Tunable Parameters” section from an x86 system with 8 GB of memory is as follows:
171614208 maximum memory allowed in buffer cache (bufhwm) 30000 maximum number of processes (v.v_proc) 99 maximum global priority in sys class (MAXCLSYSPRI) 29995 maximum processes per user id (v.v_maxup) 30 auto update time limit in seconds (NAUTOUP) 25 page stealing low water mark (GPGSLO) 1 fsflush run rate (FSFLUSHR) 25 minimum resident memory for avoiding deadlock (MINARMEM) 25 minimum swapable memory for avoiding deadlock (MINASMEM)
