Orion Is A QML / C++ Twitch Desktop Client With VODs And Chat Support
Orion is a free and open source QML / C++ client for Twitch.tv which can use multiple player backends (including mpv). The application runs on Linux, Windows, macOS and Android.
Using Orion you can watch live Twitch streams and past broadcasts, and browse or search games and channels using a nice material user interface. What’s more, Orion lets you login to Twitch, so you can chat and follow channels (and receive notifications when a channel you follow goes online).
The application allows customizing various aspects, like changing the stream quality, switching between light and dark user interface themes, and changing the chat position and font size.
Main Orion Twitch client features:
Here’s how Orion works. When you go to the channels list, you’ll notice that each channel uses its icon as a thumbnail, with the channel name in an overlay on top of the icon:
I would have liked to see the stream title, number of current viewers, and a preview in the channel list, or have an option for this. These are available, but not directly in the channel list. You can see a channel preview on mouse over, while the stream title and viewer count are available after you click on a channel:
From this bottom overlay (which is displayed after you click on a channel) you can start playing the stream, follow or unfollow the channel, open the chat without watching the stream, or access past videos. You can also right click a channel to access these options.
In the player view you’ll find the regular video player controls, along with the quality selector (with source as the default quality) at the bottom, while the top overlay lets you follow / unfollow a channel or toggle the chat, which is displayed on the right-hand side of the screen by default:
The chat panel uses autohide by default, but you can force it to always be displayed by clicking the lock icon its upper left corner. When the chat is locked (set to always visible), the video is shifted to the left so the chat isn’t displayed on top of the video, and the chat width is resizable.
Download Orion
The Orion GitHub project page doesn’t offer any Linux binaries for download, but there are packages out there for multiple Linux distributions:
In case you’re using a different Linux distribution, you’ll need to search for Orion packages for yourself or build it from source.
If you prefer to build Orion from source on Debian/Ubuntu-based Linux distributions (with mpv as the backend), here’s how to compile it. Orion requires Qt 5.8 or newer! That means you’ll need Ubuntu 18.04 / Linux Mint 19 to build it, or if you want to compile it in an older Ubuntu version, you’ll need to install a newer Qt version from a PPA, etc.
1. Install the required dependencies on your Debian/Ubuntu-based Linux distribution:
2. Download (using wget), build and install Orion:
If you want to build a different Orion version, make sure you adjust the first 3 commands with the exact file/version name.
Fixing the default Orion theme when using QT_STYLE_OVERRIDE (not required in most cases)
I use Kvantum to style Qt5 applications on my Gnome desktop, and export the Kvantum style using QT_STYLE_OVERRIDE . Due to this, Orion does not use its default theme which causes some fonts to be invisible or hard to read.
This is how Orion looks when used with Kvantum set as the QT_STYLE_OVERRIDE :
If you’re in the same situation, you can fix the Orion theme by launching the application like this:
To change the Orion desktop file to include this so you can launch Orion from your menu and have it use the correct theme, copy the Orion desktop file from /usr/share/applications/ to
/.local/share/applications/ , edit it in this second location and change Exec=orion to Exec=env QT_STYLE_OVERRIDE= orion
You can do all of this from a terminal using these commands:

Oracle internals, debugging and undocumented features
ORION (Oracle I/O Calibration Tool) included in 11g R2
Apparently Oracle included this tool into 11g release 2 database.Orion binary is located under $ORACLE_HOME/bin .
Quick run with help command will give very detail explanation how to use this tool.Also
Kevin Closson’s Oracle blog got post about Orion:
-bash-3.2$ orion -help
ORION: ORacle IO Numbers — Version 11.2.0.1.0
ORION runs IO performance tests that model Oracle RDBMS IO workloads.
It measures the performance of small (2-32K) IOs and large (128K+) IOs
at various load levels.
Each Orion data point is a test for a specific mix of small and large
IO loads sustained for a duration. An Orion test consists of multiple
data point tests. These data point tests can be represented as a
two-dimensional matrix. Each column in the matrix represents data
point tests with the same small IO load, but varying large IO loads.
Each row represents data point tests with the same large IO load, but
varying small IO loads. An Orion test can be for a single point, a
single row, a single column, or the whole matrix.
The ‘run’ parameter is the only mandatory parameter. Defaults
are indicated for all other parameters. For additional information on
the user interface, see the Orion User Guide.
is the prefix used for all input and output filenames. By
default, it is ‘orion’. It can be specified with the ‘testname’
parameter.
.lun should contain a carriage-return-separated list of LUNs.
The output files for a test run are prefixed by _ where
date is “yyyymmdd_hhmm”.
The output files are:
_ _summary.txt – Summary of the input parameters, along with
the minimum small IO latency (in usecs), the maximum
MBPS, and the maximum IOPS observed.
_ _mbps.csv – Performance results of large IOs in MBPS.
_ _iops.csv – Performance results of small IOs in IOPS.
_ _lat.csv – Latency of small IOs (in usecs).
_ _trace.txt – Extended, unprocessed output.
WARNING: IF YOU ARE PERFORMING WRITE TESTS, BE PREPARED TO LOSE ANY DATA STORED
ON THE LUNS.
Mandatory parameters:
run Type of workload to run (simple, normal, advanced, dss, oltp).
simple – Tests random small (8K) IOs at various loads,
then random large (1M) IOs at various loads.
normal – Tests combinations of random small (8K) IOs and
random large (1M) IOs.
advanced – Tests the workload specified by the user
using optional parameters.
dss – Tests with random large (1M) IOs at increasing
loads to determine the maximum throughput.
oltp – Tests with random small (8K) IOs at increasing
loads to determine the maximum IOPS.
Optional parameters:
testname Name of the test run.
num_disks Number of disks (physical spindles). This number is
used to gauge the range of loads that Orion should test
at. Increasing this parameter results in Orion using
heavier IO loads. Default is the number of LUNs in
.lun.
size_small Size of small IOs in KB. Default is 8.
size_large Size of large IOs in KB. Default is 1024.
type Type of large IOs (rand, seq). Default is rand.
rand – Randomly distributed large IOs.
seq – Sequential streams of large IOs.
num_streamIO Number of concurrent IOs per stream. This parameter is only
used if -type is seq. Default is 4.
simulate Orion tests on a virtual LUN formed by combining the
specified LUNs in one of these ways. This parameter is
typically only used if -type is seq. Default is concat.
concat – A serial concatenation of the LUNs. Each
sequential stream issues IOs to only one LUN.
raid0 – A RAID-0 mapping across the LUNs. Each
sequential stream issues IOs across all LUNs,
using RAID-0 striping.
write Percentage of IOs that are writes (SEE WARNING ABOVE).
Default is 0.
cache_size Size in MBs of the array’s cache.
Unless this option is set to 0, Orion issues a number
of unmeasured, random IOs before each large sequential
data point. These IOs fill up the storage array’s cache
(if any) with random data so that IOs from one
data point do not result in cache hits for the next
data point. Read tests are preceded with junk reads
and write tests are preceded with junk writes. If
specified, this ‘cache warming’ is performed until
cache_size MBs of IO have been read or written.
Default behavior is to issue 2 minutes of unmeasured random
IOs before each data point.
duration Duration of each data point in seconds. Default is 60.
num_small Number of outstanding small IOs. This parameter controls the
small IO load. Only used if -matrix is point, col, or max.
No default.
num_large This parameter controls the large IO load.
For -type rand, number of outstanding large IOs.
For -type seq, number of sequential IO streams. Only used
if -matrix is point, row, or max. No default.
matrix An Orion test consists of multiple data point tests. These data
point tests can be represented as a two-dimensional matrix.
Each column in the matrix represents data point tests with
the same small IO load, but varying large IO loads. Each
row represents data point tests with the same large IO load,
but varying small IO loads. An Orion test can be for a
single point, a single row, a single column, or the whole
matrix, depending on the matrix option setting below.
Default is basic.
basic – Test small IOs only, then large IOs only.
detailed – Test entire matrix.
point – Test with num_small small IOs, num_large large
IOs.
col – Test a varying large IO load with num_small
small IOs.
row – Test a varying small IO load with num_large
large IOs.
max – Test varying loads up to the num_small and
num_large limits.
verbose Prints tracing information to standard output if set.
Not set by default.
Examples:
For a preliminary set of data
-run simple
For a basic set of data
-run normal
