Operating Systems Solaris Where is my memory? How to fix it ? Post 303037773 by gull04 on Tuesday 13th of August 2019 08:29:52 AM

Hi,

I'm not really a great fan of trying things out on production servers, it always seems to come back and bite you from an other direction. If your environment is anything like most of the ones I have worked in over the years, test and development machines seem to be scarce and if they exist - getting testing resource is like finding a winning lottery ticket.

It's a difficult call for me, I don't know anything about your environment other than you are using Solaris 11.2, one server has 36Gb of memory, the other has 16Gb of memory and they could be whole root zones. And of course the fact that both servers are reporting almost 90% memory utilisation which will trigger an alert.

Much of this is going to come down to a few things here;
  1. Can you do this on a Test/Dev sever?
  2. Does going ove 90% memory utilisation cause a problem with the application.
  3. Can you live with the alert generated at the 90% threshold, can it be ignored or the threshold changed.
  4. Do you have to try this change in a production environment, if there are problems whats the regression?
  5. How critical is the production server, if it's critical could you test on the DR server?
  6. Will your boss back you up if you take the iteritive approach and set "user_reserve_hint_pct" to 60% as Oracle suggest.

I know the above isn't overly helpful, but asking someone with no experience of the environment in which you work just opens up many more questions than can't be easilly answered in a forum such as this.

My preferred approach to this would be to run an explorer over the system and raise a support ticket (case) with Oracle support, in the ticket you should cite your concerns - please be aware that Oracle may well come back and suggest things like the patching is brought up to date for the systems.

Regards

NAME
Paraview - Rendering and displaying program for small and large, three dimensional datasets. SYNOPSIS
paraview [-cc | --cave-configuration FILE] [--compare-view OPT] [--connect-id ID] [--data DATA] [--data-directory DIR] [-dr | --disable- registry] [--exit] [/? | --help] [--image-threshold THRESH] [-m | --machines FILE] [--run-test CASE] [--run-test-init CASE] [-s | --server NAME] [--stereo] [--test-directory DIR] [-V | --version] DESCRIPTION
Paraview is a program for displaying and rendering of small to large datasets in two or three dimensions. It runs on a single computer or on a cluster of nodes with distributed or shared memory. The Visualization Toolkit (VTK) is used as processing and rendering machine. Options -cc | --cave-configuration FILE Specify the file FILE that defines the displays for a cave. It is used only with CaveRenderModule. --compare-view OPT Compare the viewport to a reference image, and exit. --connect-id ID Set the ID of the server and client to make sure they match. --data DATA Load the specified DATA. --data-directory DIR Set the data DIR directory where test-case data are. -dr | --disable-registry Do not use registry when running ParaView (for testing). --exit Exit application when testing is done. Use for testing. /? | --help Displays available command line arguments. --image-threshold THRESH Set the threshold THRESH beyond which viewport-image comparisons fail. -m | --machines FILE Specify the network configurations file FILE for the render server. --run-test CASE Run a recorded test case CASE. --run-test-init CASE Run a recorded test initialization case CASE. -s | --server NAME Set the name NAME of the server resource to connect with when the client starts. --stereo Tell the application to enable stereo rendering (only when running on a single process). --test-directory DIR Set the temporary directory DIR where test-case output will be stored. -V | --version Give the version number and exit.
