rlim_fd_sys Parameter

Description

Specifies the maximum limit to which a process can raise its hard limit on file descriptors. This parameter specifies the system maximum value for the process.max-file-descriptor resource control.

You cannot override this limit. You can only change this limit if your system runs at least Oracle Solaris 11.4 SRU 27.

Data Type

Unsigned integer

Default

MAXINT through Oracle Solaris 11.4 SRU 26

Starting with Oracle Solaris 11.4 SRU 27, calculated based on physmem to be approximately 65K per gigabyte of memory. The value is rounded up to the nearest value of (2^N)-1.

Range

128 to MAXINT

Dynamic?

No

Validation

Compared to rlim_fd_max. If rlim_fd_sys is less than rlim_fd_max, rlim_fd_sys is reset to rlim_fd_max

When to Change

When the maximum hard limit of open files for a process is insufficient or when a system restricts the maximum hard limit for privileged processes

Commitment Level

Unstable
