Oracle database for windows server 2012

Before you launch into this installation, here are a few things to consider.

• The finished system includes the host operating system, two guest operating systems, two sets of Oracle Grid Infrastructure (Clusterware + ASM) and two Database instances all on a single server. As you can imagine, this requires a significant amount of disk space, CPU and memory.
• Following on from the last point, the VMs will each need at least 3G of RAM, preferably 4G if you don’t want the VMs to swap like crazy. Don’t assume you will be able to run this on a small PC or laptop. You won’t.
• This procedure provides a bare bones installation to get the RAC working. There is no redundancy in the Grid Infrastructure installation or the ASM installation. To add this, simply create double the amount of shared disks and select the «Normal» redundancy option when it is offered. Of course, this will take more disk space.
• During the virtual disk creation, I always choose not to preallocate the disk space. This makes virtual disk access slower during the installation, but saves on wasted disk space. The shared disks must have their space preallocated.
• This is not, and should not be considered, a production-ready system. It’s simply to allow you to get used to installing and using RAC.
• The Single Client Access Name (SCAN) should be defined in the DNS or GNS and round-robin between one of 3 addresses, which are on the same subnet as the public and virtual IPs. Prior to 11.2.0.2 it could be defined as a single IP address in the «/etc/hosts» file, which is wrong and will cause the cluster verification to fail, but it allowed you to complete the install without the presence of a DNS. This does not seem to work for 11.2.0.2 onward.
• The virtual machines can be limited to 2Gig of swap, which causes a prerequisite check failure, but doesn’t prevent the installation working. If you want to avoid this, define 3+Gig of swap.
• This article uses the 64-bit versions of Windows and Oracle 11g Release 2.
• In this article I am using a Oracle Linux as my host OS.

Download Software

Download the following software.

• VirtualBox
• Oracle Database 12c Release 1 (12.1.0.1.0) Grid and DB software

VirtualBox Installation

First, install the VirtualBox software. On RHEL and its clones you do this with the following command as the root user.

# rpm -Uvh VirtualBox-4.2-4.2.16_86992_el6-1.x86_64.rpm

The package name will vary depending on the host distribution you are using. Once complete, VirtualBox is started from the menu.

Virtual Machine Setup

Now we must define the two virtual RAC nodes. We can save time by defining one VM, then cloning it when it is installed.

Start VirtualBox and click the «New» button on the toolbar. Enter the name «w2012-121-rac1», OS «Microsoft Windows» and Version «Windows 2012 (64 bit)», then click the «Next» button.

Enter «4096» as the base memory size, then click the «Next» button.

Accept the default option to create a new virtual hard disk by clicking the «Create» button.

Accept the default hard drive file type by clicking the «Next» button.

Accept the «Dynamically allocated» option by clicking the «Next» button.

Accept the default location and set the size to «30G», then click the «Create» button. If you can spread the virtual disks onto different physical disks, that will improve performance.

The «w2012-121-rac1» VM will appear on the left hand pane. Scroll down the details on the right and click on the «Network» link.

Make sure «Adapter 1» is enabled, set to «Bridged Adapter», then click on the «Adapter 2» tab.

Make sure «Adapter 2» is enabled, set to «Internal Network», then click on the «System» section.

Move «Hard Disk» to the top of the boot order and uncheck the «Floppy» option, then click the «OK» button.

The virtual machine is now configured so we can start the guest operating system installation.

Guest Operating System Installation

With the new VM highlighted, click the «Start» button on the toolbar. On the «Select start-up disk» screen, choose the relevant Oracle Linux ISO image and click the «Start» button.

The resulting console window will contain the Windows 2012 boot screen.

Continue through the Full Standard Edition installation as you would for a normal server. In this case I was using an evaluation version of Windows 2012, so I picked the «Windows Server 2012 Standard Evaluation (Server with a GUI)» option. Pick the custom install when doing a fresh installation.

When the installation is complete, install the VirtualBox Guest Additions on the server. This is initiated from the «Devices > Install Guest Additions…» menu. Accept all the defaults and reboot the server when requested.

Create a shared folder (Devices > Shared Folders) on the virtual machine, pointing to the directory on the host where the Oracle software was unzipped. Check the «Auto-mount» and «Make Permanent» options before clicking the «OK» button.

The VM will need to be restarted for the guest additions to be used properly. The next section requires a shutdown so no additional restart is needed at this time. Once the VM is restarted, the shared folder will be available as the «E:\» drive.

Oracle Installation Prerequisites

Perform the following steps whilst logged into the virtual machine.
Turn off the Windows firewall «Server Manager > Local Server > Windows Firewall > Public:On > Turn Windows Firewall on or off» to prevent it from interfering with the sever communication. You can turn it on later and open up any required ports if you want to.

Amend the «C:\windows\system32\drivers\etc\hosts» file to contain the following information. Even if you are using DNS to resolve the SCAN, include the SCAN entries in the «hosts» files. Without them the installer had trouble recognising the SCAN.

127.0.0.1       localhost.localdomain   localhost
# Public
192.168.0.151   w2012-121-rac1.localdomain          w2012-121-rac1
192.168.0.152   w2012-121-rac2.localdomain          w2012-121-rac2

# Private
192.168.1.151   w2012-121-rac1-priv.localdomain     w2012-121-rac1-priv
192.168.1.152   w2012-121-rac2-priv.localdomain     w2012-121-rac2-priv

#Virtual
192.168.0.153   w2012-121-rac1-vip.localdomain      w2012-121-rac1-vip
192.168.0.154   w2012-121-rac2-vip.localdomain      w2012-121-rac2-vip

# SCAN
192.168.0.155   w2012-121-scan.localdomain          w2012-121-scan
192.168.0.156   w2012-121-scan.localdomain          w2012-121-scan
192.168.0.157   w2012-121-scan.localdomain          w2012-121-scan

Open the «Network Connections» screen (Server Manager > Local Server > Ethernet (click link next to it)). Rename the «Ethernet» to «public» and «Ethernet 2» to «private», making sure you apply the names to the appropriate connections. You can do this by right-clicking on the connection and selecting «Rename» from the pop-up menu.

Set the correct IP information for the public and private connections. Right-click on a connection and select the «Properties» menu option. Click on «Internet Protocol Version 4 (TCP/IPv4)» option and click the «Properties. button. Enter the appropriate IP, subnet, default gateway and DNS for the networks.

public:

• IP Address: 192.168.0.151
• Subnet: 255.255.255.0
• Default Gateway: 192.168.0.1
• DNS: 192.168.0.6

private:

• IP Address: 192.168.1.151
• Subnet: 255.255.255.0
• Default Gateway: N/A
• DNS: N/A

Click on the «Advanced» button, followed by the «DNS» tab. Select the «Append these DNS suffixes (in order)» option and add the domain suffix, in this case «localdomain». Use the «OK» buttons to exit the dialogs.

Note. It’s worth double-checking the MAC addresses of the network adapters in the VM against those of the network interfaces on the guest operating system. Make sure the public interface is the bridged connection. The guest OS sometimes shows the interfaces out of order.

If any of the network connections are left in a disabled state, right-click on then and select the «Diagnose» option to repair them.

Ensure the public interface is first in the bind order:

• On the «Network Connections» dialog, press «Alt+N» to show the advanced menu. Select «Advanced Settings…».
• On the «Adapters and Bindings» tab, make sure the public interface is the first interface listed.
• Click on each network in turn and make sure the «TCP/IPv4» bindings come before the «TCP/IPv6» bindings. This should be correct by default.
• Accept any modifications by clicking on the «OK» button and exiting the «Network Connections» dialog.

Disable Windows Media Sensing for TCP/IP:

• Backup the Windows registry.
• Run the Registry Editor (Regedit.exe) and find the following key.
  

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

• Add the following registry value.
  

  Value Name: DisableDHCPMediaSense
  Data Type: DWORD
  Value: 1

• This change will not take effect until the computer is restarted.

Open the «System Properties» dialog (Start > Control Panel > System and Security > System > Change Settings) and do the following:

• Click the «Change» button, enter the machine name «w2012-121-rac1» then click the «OK» button.
• Click on the Advanced tab and the «Environment Variables» button.
• Edit both the «TEMP» and «TMP» environment variables to be «%WINDIR%\temp», which is «C:\Windows\temp».
• Click the «OK» button and «Apply» out of the «System» dialog.

Restart the server.

Create Shared Disks

Make sure the VM is shutdown, create a directory to host the shared virtual disks on the host OS, then create the shared disks. My host is Linux, so the paths to the virtual disks are UNIX-style paths. If your host is Windows, then you will be using Windows-style paths.

mkdir
-p /u04/VirtualBox/w2012-121-rac

cd
/u04/VirtualBox/w2012-121-rac

#
Create the disks and associate them with VirtualBox as virtual media.

VBoxManage
createhd —filename asm4.vdi —size 5120 —format VDI —variant Fixed

#
Connect them to the VM.

VBoxManage

VBoxManage
modifyhd asm1.vdi —type shareable

VBoxManage
modifyhd asm2.vdi —type shareable

VBoxManage

VBoxManage
modifyhd asm4.vdi —type shareable

Start the w2012-121-rac1 virtual machine by clicking the «Start» button on the toolbar. When the server has started, log in so you can partition the disks.

We will partition the disks using the «DiskPart» utility. To get alist of the current disks do the following.

C:\>diskpart

Microsoft DiskPart version 6.0.6001
Copyright (C) 1999-2007 Microsoft Corporation.
On computer: RAC1

DISKPART> list disk

  Disk ###  Status      Size     Free     Dyn  Gpt

  Disk 3    Online        10 GB    10 GB
  Disk 4    Online        10 GB    10 GB

DISKPART>

In the diskpart utility we will perform the following commands.

automount enable
select disk 1
create partition extended
create partition logical
select disk 2
create partition extended
create partition logical
select disk 3
create partition extended
create partition logical
select disk 4
create partition extended
create partition logical
exit

Stamp the disks for use with ASM. This is done using the asmtool that comes with the Grid Infrastructure media.

E:> cd grid\asmtool
E:> asmtool -add \Device\HardDisk1\Partition1 ORCLDISK1
E:> asmtool -add \Device\HardDisk2\Partition1 ORCLDISK2

The shared disks are now configured.

Clone the Virtual Machine

VirtualBox allows you to clone VMs, but these also attempt to clone the shared disks, which is not what we want. Instead we must manually clone the VM.

Shutdown the «w2012-121-rac1» VM.

Manually clone the virtual disk using the following commands on the host server.

mkdir -p /u03/VirtualBox/w2012-121-rac2

VBoxManage clonehd /u02/VirtualBox/w2012-121-rac1/w2012-121-rac1.vdi /u03/VirtualBox/w2012-121-rac2/w2012-121-rac2.vdi

Create the «w2012-121-rac2» virtual machine in VirtualBox in the same way as you did for «w2012-121-rac1», with the exception of using an existing «w2012-121-rac2.vdi» virtual hard drive.
Remember to add the three network adaptors as you did on the first VM. When the VM is created, attach the shared disks to this VM.

cd /u04/VirtualBox/w2012-121-rac

VBoxManage storageattach w2012-121-rac2 —storagectl «SATA» —port 1 —device 0 —type hdd —medium asm1.vdi —mtype shareable

VBoxManage storageattach w2012-121-rac2 —storagectl «SATA» —port 2 —device 0 —type hdd —medium asm2.vdi —mtype shareable

VBoxManage storageattach w2012-121-rac2 —storagectl «SATA» —port 3 —device 0 —type hdd —medium asm3.vdi —mtype shareable

VBoxManage storageattach w2012-121-rac2 —storagectl «SATA» —port 4 —device 0 —type hdd —medium asm4.vdi —mtype shareable

Start the «w2008-112-rac2» virtual machine.

Open the «Network Connections» screen (Server Manager > Local Server > Ethernet (click link next to it)) and amend the IP address values of each network to the appropriate values for the second node.
Open the «System Properties» dialog (Start > Control Panel > System and Security > System > Change Settings) and change the machine name by clicking the «Change» button. Click all «OK» buttons to exit the «System Properties» dialog and restart the server when prompted.

Once the RAC2 virtual machine has restarted, start the RAC1 virtual machine. When both nodes have started, check they can both ping all the public and private IP addresses using the following commands.

ping w2012-121-rac1
ping w2012-121-rac1-priv
ping w2012-121-rac2
ping w2012-121-rac2-priv

At this point the virtual IP addresses defined in the hosts file will not work, so don’t bother testing them.

The virtual machine setup is now complete.

Before moving forward you should probably shut down your VMs and take snapshots of them. If any failures happen beyond this point it is probably better to switch back to those snapshots, clean up the shared drives and start the grid installation again. An alternative to cleaning up the shared disks is to back them up now using zip and just replace them in the event of a failure.

$ cd /u04/VirtualBox/w2012-121-rac
$ zip PreGrid.zip *.vdi

Install the Grid Infrastructure

Make sure both virtual machines are started. Login to «w2012-121-rac1» and start the Oracle installer.

e:
cd grid
setup.exe

Select the «Skip software updates» option, then click the «Next» button.

Select the «Install and Configure Oracle Grid Infrastructure for a Cluster» option, then click the «Next» button.

Select the «Typical Installation» option, then click the «Next» button.

On the «Specify Cluster Configuration» screen, enter the correct SCAN Name and click the «Add» button.

Enter the details of the second node in the cluster, then click the «OK» button.

Click the «Identify network interfaces…» button and check the public and private networks are specified correctly. Remember to mark the NAT interface as «Do Not Use». Once you are happy with them, click the «OK» button and the «Next» button on the previous screen.

Enter the ORACLE_BASE of «c:\app\12.1.0.1», a software location of «c:\app\12.1.0.1\grid» and the SYSASM password. click the «Next» button.

Set the redundancy to «External», select all 4 disks and click the «Next» button.

Wait while the prerequisite checks complete. If you have any issues, either fix them or check the «Ignore All» checkbox and click the «Next» button. It is likely the «Windows firewall status», «Physical Memory» and «Administrator» tests will fail for this type of installation.

If you are happy with the summary information, click the «Install» button.

Wait while the setup takes place.

Click the «Close» button to exit the installer.

The grid infrastructure installation is now complete. We can check the status of the installation using the following commands.

C:\>C:\app\12.1.0.1\grid\bin\crsctl stat res -t

At this point it is probably a good idea to shutdown both VMs and take snapshots. Remember to make a fresh zip of the ASM disks on the host machine, which you will need to restore if you revert to the post-grid snapshots.

$ cd /u04/VirtualBox/w2012-121-rac
$ zip PostGrid.zip *.vdi

Install the Database Software

Make sure the «w2012-121-rac1» and «w2012-121-rac2» virtual machines are started, then login to «w2012-121-rac1» and start the Oracle installer.

e:
cd database
setup.exe

Uncheck the security updates checkbox and click the «Next» button and «Yes» on the subsequent warning dialog.

Check the «Skip software updates» checkbox and click the «Next» button.

Select the «Install database software only» option, then click the «Next» button.

Accept the «Oracle Real Application Clusters database installation» option by clicking the «Next» button.

Make sure both nodes are selected, then click the «Next» button.

Select the required languages, then click the «Next» button.

Select the «Enterprise Edition» option, then click the «Next» button.

Decide the credentials for the database user, then click the «Next» button. In this case I picked the «Use Windows Built-in Account» option, which is not recommended. If you pick this option, accept the following warning dialog.

Enter «c:\app\oracle» as the Oracle base and «c:\app\oracle\product\12.1.0.1\db_1» as the software location, then click the «Next» button.

Wait for the prerequisite check to complete. If there are any problems either fix them, or check the «Ignore All» checkbox and click the «Next» button.

If you are happy with the summary information, click the «Install» button.

Wait while the installation takes place.

Click the «Close» button to exit the installer.

Shutdown both VMs and take snapshots. Remember to make a fresh zip of the ASM disks on the host machine, which you will need to restore if you revert to the post-db snapshots.

$ cd /u04/VirtualBox/w2012-121-rac
$ zip PostDB.zip *.vdi

Create a Database

Make sure the «w2012-121-rac1» and «w2012-121-rac2» virtual machines are started, then login to «w2012-121-rac1» and start the Database Creation Asistant (DBCA).

c:\>dbca

Select the «Create Database» option and click the «Next» button.

Select the «Create a database with default configuration» option. Enter the container database name (cdbrac), pluggable database name (pdbrac) and administrator password. Click the «Next» button.

Wait for the prerequisite checks to complete. If there are any problems either fix them, or check the «Ignore All» checkbox and click the «Next» button.

If you are happy with the summary information, click the «Finish» button.

Wait while the database creation takes place.

If you want to modify passwords, click the «Password Management» button. When finished, click the «Exit» button.

Click the «Close» button to exit the DBCA.

The RAC database creation is now complete.

Check the Status of the RAC

There are several ways to check the status of the RAC. The srvctl utility shows the current configuration and status of the RAC database.

— Берем два первых диска дистрибутива. Для данной версии это p17694377_121020_MSWIN-x86-64_1of8.zip и p17694377_121020_MSWIN-x86-64_2of8.zip. Разархивируем оба в одну и ту же папку на диске. Запускаем setup.exe.

— На первом экране предлагается ввести адрес электронной почты или учетную запись My Oracle Support (MOS). Cнимаем галочку «I wish to receive security updates via My Oracle Support» — «Я хочу получать обновления безопасности с помощью My Oracle Support».

— Подтверждаем что будем оставаться в неведении по поводу важнейших вопросов безопасности в нашей конфигурации?

— (Этого экрана может и не быть). Здесь предлагается скачать (если есть учетная запись MOS) или указать на уже скачанное обновление, которое будет применено в процессе установки Oracle. Отказываемся от этого, выбираем «Skip software updates» — «Пропустить обновление ПО».

— Предлагается три варианта:

1) Во время установки создать и сконфигурировать БД — «Create and configure a database«;

2) Только установить Oracle и больше ничего — «Install database software only«;

3) Во время установки обновить существующую базу (это если вы обновляетесь с одной версии Oracle на другую) — «Upgrade an existing database«.

Выбираем вариант 2.

— Выбираем тип установки:

1) Одиночный экземпляр «Single instance database installation«;

2) Oracle RAC (кластер) «Oracle Real Application Clusters database installation«;

3) Oracle RAC One Node (кластер из одного узла) «Oracle RAC One Node database installation«;

Выбираю вариант 1.

— Выбираем язык. Здесь обязательно нужно добавить русский язык «Russian«.

— Выбираем вариант установки. Я выбираю Enterprise Edition.

— Для повышения безопастности можно создать или указать уже созданного пользователя ОС от лица которого будут запускаться службы Oracle и назначены права на файлы в Oracle Home. Создаем нового пользователя — oracle.

— Выбираем папки для установки.

— Здесь проверка минимальных требований. Если она успешна, то увидим этот экран. Это суммарная информация по установке и последний шанс что-то еще поменять.

— Установка запущена, идет копирование файлов.

— Oracle установлен.

The goal in this post is to install an Oracle database 12.2 on windows server 2012. Here we separate our job into 2 major steps:

1. Install Oracle 12.2 Software
2. Create Oracle 12.2 Database
3. Open Port 1521 and 5500

A. Install Oracle 12.2 Software

First of all, you must have the installation source, then click setup.exe.

In this step, we install Oracle software only and create a database later.

Even though «Use Virtual Account» is the default option, I choose «Create New Windows User» for Oracle Home User. This is the safest way to do it.

Do you see that? OUI automatically selects the new drive E other than drive C for ORACLE_BASE and ORACLE_HOME. Is it because I put the installation package of Oracle database 12.2 in drive E?

B. Create Oracle 12.2 Database

Use ⊞ Win + F to search for DBCA function, then click it.

Please note that, don’t use CMD to call DBCA, it will fail later.

Click Customize Storage Locations... to change the size of redo logs.

Open Port 1521 and 5500

One last move is to open port 1521 for your incoming connections on windows server.
