sysdef Command

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 a SPARC T3-4 system with 500 GB of memory is as follows:

2206203904      maximum memory allowed in buffer cache (bufhwm)
65546           maximum number of processes (v.v_proc)
99              maximum global priority in sys class (MAXCLSYSPRI)
65541           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)
