1
00:00:01,310 --> 00:00:03,770
In this lesson, we're going to
take a look at the operating
2
00:00:03,770 --> 00:00:05,930
systems that Oracle offers.
3
00:00:05,930 --> 00:00:07,830
In order to run
an Oracle database
4
00:00:07,830 --> 00:00:10,040
you must, of course, have
an operating system running
5
00:00:10,040 --> 00:00:13,640
on the server itself, whether
it's an Exadata machine or just
6
00:00:13,640 --> 00:00:15,530
your home computer.
7
00:00:15,530 --> 00:00:17,840
The Oracle database can run
on many different operating
8
00:00:17,840 --> 00:00:20,540
systems, but Oracle
offers two of their own.
9
00:00:20,540 --> 00:00:22,880
When Oracle acquired
Sun Microsystems,
10
00:00:22,880 --> 00:00:25,550
not only did they acquire
Sun's hardware footprint
11
00:00:25,550 --> 00:00:27,560
but their software
assets as well.
12
00:00:27,560 --> 00:00:31,040
This included Solaris, Sun's
popular version of Unix.
13
00:00:31,040 --> 00:00:32,750
While there was
some initial concern
14
00:00:32,750 --> 00:00:34,880
that Oracle would
discontinue Solaris
15
00:00:34,880 --> 00:00:36,560
the reality was quite different.
16
00:00:36,560 --> 00:00:38,990
Oracle continues to
support and even expand
17
00:00:38,990 --> 00:00:41,650
the capabilities of Solaris.
18
00:00:41,650 --> 00:00:44,440
The current version
stands at Solaris 11,
19
00:00:44,440 --> 00:00:48,380
and Solaris 10 is
supported as well.
20
00:00:48,380 --> 00:00:50,240
This is Oracle Solaris.
21
00:00:50,240 --> 00:00:52,820
One of the really unique
things about Oracle Solaris,
22
00:00:52,820 --> 00:00:55,360
it runs on more than
one ship architecture.
23
00:00:55,360 --> 00:00:57,770
Sun Hardware, now
Oracle Hardware,
24
00:00:57,770 --> 00:01:00,540
uses the SPARC
chip architecture.
25
00:01:00,540 --> 00:01:03,240
So naturally, Solaris
runs on SPARC hardware.
26
00:01:03,240 --> 00:01:05,420
However, Solaris
has also been ported
27
00:01:05,420 --> 00:01:09,350
to the everyday x86-based
chip architecture, which
28
00:01:09,350 --> 00:01:12,350
means you can install and run
Solaris on commercial grade
29
00:01:12,350 --> 00:01:16,070
hardware, such as smaller
to mid-sized x86 servers.
30
00:01:16,070 --> 00:01:18,840
You can even run it
on your home computer.
31
00:01:18,840 --> 00:01:20,790
Just to take a look here
at some of the things
32
00:01:20,790 --> 00:01:21,990
Solaris has to offer.
33
00:01:27,290 --> 00:01:30,610
So this is a typical interface
that people are familiar with,
34
00:01:30,610 --> 00:01:32,540
the Firefox web browser.
35
00:01:32,540 --> 00:01:33,910
This would be just
the same as it
36
00:01:33,910 --> 00:01:39,500
would be in Windows or Linux
or any other operating system.
37
00:01:39,500 --> 00:01:44,190
When we want to browse files
out in the directories,
38
00:01:44,190 --> 00:01:48,170
we can use a file browser lets
us see directories or folders
39
00:01:48,170 --> 00:01:49,460
out on the operating system.
40
00:01:53,240 --> 00:01:55,360
And when we need to
shut down, we simply
41
00:01:55,360 --> 00:01:59,050
choose the Shut Down option
from the GUI interface.
42
00:02:01,750 --> 00:02:04,110
In addition to
Solaris, Oracle also
43
00:02:04,110 --> 00:02:08,370
offers its own version of Linux
operating system, Oracle Linux.
44
00:02:08,370 --> 00:02:10,890
Linux on Oracle has an
interesting history.
45
00:02:10,890 --> 00:02:13,290
Oracle is one of the very
first major companies
46
00:02:13,290 --> 00:02:16,980
to openly support Linux
and create software for it.
47
00:02:16,980 --> 00:02:19,830
Oracle ported the Oracle
database server to Linux
48
00:02:19,830 --> 00:02:23,640
as early as the late 1990s all
the way back to Oracle Version
49
00:02:23,640 --> 00:02:24,900
8.
50
00:02:24,900 --> 00:02:28,380
They continued to support
Oracle on Linux for many years.
51
00:02:28,380 --> 00:02:31,620
In the 2000s, they released
their own distribution,
52
00:02:31,620 --> 00:02:33,770
Oracle Linux.
53
00:02:33,770 --> 00:02:36,980
Oracle Linux, at this point,
was simply a rebranded RedHat
54
00:02:36,980 --> 00:02:40,040
distribution, which means it
was literally no different
55
00:02:40,040 --> 00:02:44,060
than RedHat Linux except the
company logos were changed.
56
00:02:44,060 --> 00:02:47,600
Since companies cannot make
money by selling Linux itself
57
00:02:47,600 --> 00:02:50,960
most, like RedHat,
charge for support.
58
00:02:50,960 --> 00:02:53,120
That is to say, if
you have problems
59
00:02:53,120 --> 00:02:55,610
you can call into their
support line and get help.
60
00:02:55,610 --> 00:02:57,740
By releasing Oracle
Linux, Oracle
61
00:02:57,740 --> 00:03:00,200
had thrown their hat into
the support arena as well.
62
00:03:00,200 --> 00:03:03,260
Now I'll login.
63
00:03:03,260 --> 00:03:05,620
This worked fine for
a while until Oracle
64
00:03:05,620 --> 00:03:09,400
began to feel that RedHat wasn't
innovating Linux at the pace
65
00:03:09,400 --> 00:03:11,000
that Oracle wanted.
66
00:03:11,000 --> 00:03:12,370
They also contended
with the fact
67
00:03:12,370 --> 00:03:15,280
that even though many companies
use RedHat Linux with Oracle
68
00:03:15,280 --> 00:03:18,310
databases, RedHat still
refused to actively test
69
00:03:18,310 --> 00:03:20,980
Oracle on RedHat in
the same way that they
70
00:03:20,980 --> 00:03:22,720
tested other products.
71
00:03:22,720 --> 00:03:25,240
This eventually led to
Oracle producing a new Linux
72
00:03:25,240 --> 00:03:29,260
kernel, the so-called
Unbreakable Enterprise Kernel.
73
00:03:29,260 --> 00:03:31,360
While still very
similar, Oracle Linux
74
00:03:31,360 --> 00:03:33,520
compiled with the
Unbreakable Kernel
75
00:03:33,520 --> 00:03:35,890
had a number of enhancements
to improve the performance
76
00:03:35,890 --> 00:03:37,840
of the Oracle database.
77
00:03:37,840 --> 00:03:40,420
It is Oracle's intention to
market this kernel as a better
78
00:03:40,420 --> 00:03:43,690
tested, high performance,
high availability kernel
79
00:03:43,690 --> 00:03:45,770
for running Oracle database.
80
00:03:45,770 --> 00:03:47,620
In addition to the
Unbreakable Kernel,
81
00:03:47,620 --> 00:03:50,950
Oracle still offers Oracle
Linux with the original RedHat
82
00:03:50,950 --> 00:03:52,030
compatible kernel.
83
00:03:56,140 --> 00:03:59,200
And if you notice here, this
is very similar to Solaris.
84
00:04:09,780 --> 00:04:11,240
A number of the
tools that it comes
85
00:04:11,240 --> 00:04:13,880
with, such as SQL
Developer, are actually
86
00:04:13,880 --> 00:04:17,230
used for managing
Oracle databases.
