Solaris Tunable Parameters Reference Manual
Previous Next

Viewing Solaris System Configuration Information

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.

For more information, see mdb(1) or kadb(1M).

sysdef Command

The sysdef command provides the values of System V IPC settings, STREAMS tunables, process resource limits, and portions of the tune and v structures. For example, the sysdef “Tunable Parameters” section from on a 512-Mbyte SunTM UltraTM 80 system is as follows:

10387456        maximum memory allowed in buffer cache (bufhwm)
    7930        maximum number of processes (v.v_proc)
      99        maximum global priority in sys class (MAXCLSYSPRI)
    7925        maximum processes per user id (v.v_maxup)
      30        auto update time limit in seconds (NAUTOUP)
      25        page stealing low water mark (GPGSLO)
       5        fsflush run rate (FSFLUSHR)
      25        minimum resident memory for avoiding deadlock (MINARMEM)
      25        minimum swapable memory for avoiding deadlock (MINASMEM)

For more information, see sysdef(1M).
