Operating Systems Solaris How the free memory threshold? Post 303016518 by hicksd8 on Saturday 28th of April 2018 04:51:54 AM

If I understand your question correctly, you are asking for an explanation of Solaris memory manager. You'd better ask Oracle that question because you are talking about Solaris kernel internals.

The operating system kernel has no reason to kick a process's memory set out of real memory until another process needs to use that real memory. Why would the kernel page out part or all of a memory set without a reason only to find that the next process to run needs it paged back in?

Therefore, it's quite normal for free memory to be low compared to actual installed real memory after the system has been running for a while. Don't worry about it unless you have a reason to.

NAME
install-solaris - install the Solaris operating system SYNOPSIS
install-solaris install-solaris invokes the Solaris Install program. Depending on graphical capability and available memory at the time of invocation, install-solaris invokes either a text-based installer or a graphical installer. The following minimum requirements for physical memory dictate which features are available during installation: For SPARC machines: 128 MB Minimum physical memory for all installation types 128 MB Minimum physical memory required for windowing system 384 MB Minimum physical memory required for graphical-based installation For x86 machines: 256 MB Minimum physical memory for all installation types 256 MB Minimum physical memory required for windowing system 512 MB Minimum physical memory required for graphical-based installation In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number of fea- tures available. install-solaris exists only on the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the for more details. install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the installation media. Refer to the for disk space requirements. Refer to the for more information on the various menus and selections.
