How To Install Exchange Server 2016 on Windows Server 2012 R2-Part-1

We are going to install Microsoft Exchange Server 2016 on Windows Server 2012 R2 Standard in Lab Environment. Before Installing MS-Exchange we need to install some prerequisite.

Make Sure your Domain Controller's functional level of forest is at least Windows Server 2008 and the schema master running is Windows Server 2008 or later.
The full installation option of Windows Server 2012 and Windows Server 2012 R2 must be used for all servers running Exchange 2016 server roles or management tools.
You must first join the computer to the appropriate internal Active Directory forest and domain.
Install the latest Windows updates on your computer.

You can check how to install Active Directory on Windows Server 2012 R2

After Joining the Exchange Server 2016 Computer to the Domain we have to do the following.

Install Pre-Req for Exchange Server 2016

login as Domain Admin Open PowerShell as Administrator
Run Following Command

Install-WindowsFeature AS-HTTP-Activation, Desktop-Experience, NET-Framework-45-Features, RPC-over-HTTP-proxy, RSAT-Clustering, RSAT-Clustering-CmdInterface, RSAT-Clustering-Mgmt, RSAT-Clustering-PowerShell, Web-Mgmt-Console, WAS-Process-Model, Web-Asp-Net45, Web-Basic-Auth, Web-Client-Auth, Web-Digest-Auth, Web-Dir-Browsing, Web-Dyn-Compression, Web-Http-Errors, Web-Http-Logging, Web-Http-Redirect, Web-Http-Tracing, Web-ISAPI-Ext, Web-ISAPI-Filter, Web-Lgcy-Mgmt-Console, Web-Metabase, Web-Mgmt-Console, Web-Mgmt-Service, Web-Net-Ext45, Web-Request-Monitor, Web-Server, Web-Stat-Compression, Web-Static-Content, Web-Windows-Auth, Web-WMI, Windows-Identity-Foundation

Reboot the Server
Install .NET Framework 4.5.2

Restart the Server
Unified Communications Managed API 4.0 Runtime

Restart the Server after setup completes

Active Directory Preparation

The computer you want to use to prepare Active Directory for Exchange 2016 has specific prerequisites that must be met.

Logon with Domain Administrator account, Open PowerShell and Install the Remote Tools Administration Pack using the following command

Install-WindowsFeature RSAT-ADDS

A schema Update is required before installing Exchange Server 2016

In PowerShell run the following to check the schema version

"Exchange Schema Version = " + ([ADSI]("LDAP://CN=ms-Exch-Schema-Version-Pt," + ([ADSI]"LDAP://RootDSE").schemaNamingContext)).rangeUpper

Now Copy Exchange server 2016 Setup files on your Exhchange Server PC and Run the following command from elevated Command prompt. This will only update the schema.

Setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms

Run the Version Check Command Again and you will see following

To prepare Active Directory run one of the following commands. Note this will also apply the schema update if you did not perform that step already. You cannnot change the Organization name later so chose wisely.

Setup.exe /PrepareAD /OrganizationName:"Mylab" /IAcceptExchangeServerLicenseTerms

Installing Exchange server 2016 Mailbox Server Role

Navigate to the location of Exchange Server 2016 Installation Files
Right Click setup.exe and select Run As Administrator

How to Install Oracle Database 11g R2 on Oracle Linux 7 with ASM

In this demo we are going to install oracle database 11gR2 with ASM (Automatic Storage Management) on Oracle Linux 7 virtual machine which we have created in previous post.

First we have shutdown the Oracle Linux 7 VM to create virtual disks for ASM disk groups. we are going to create three virtual hard disks with following names.

CRSDISK1 ( 2GB) – for CRSVOL1 disk where Cluster Ready Services (CRS) files will be stored. CRS provides many system management services and interacts with the vendor clusterware to coordinate cluster membership information.
DATADISK1 (10 GB) – disk for DATAVOL1 disk. Here database will keep all datafiles, control files, log files
FRADISK1 (10 GB) – disk for FRAVOL1 disk for database Fast Recovery Area (FRA) files. For example: database backup files, copy of database control files.

Open Virtual machine Settings and create new virtual hard disks.

After creating new virtual hard disks lets power on the virtual machine,
Now we have to create recommended groups and user for Grid infrastructure. It is recommended to use a separate user from an oracle user.

[root@OEL7 ~]# groupadd -g 1200 asmdba
[root@OEL7 ~]# groupadd -g 1201 asmadmin
[root@OEL7 ~]# groupadd -g 1202 asmoper

[root@OEL7~]# useradd -m -u 1100 -g oinstall -G asmdba,asmadmin,asmoper,dba -d /home/grid -s /bin/bash grid
[root@OEL7 ~]# id grid

To set the password for user grid.
[root@OEL7 ~]# passwd grid

To Create directories for grid home

[root@OEL7 ~]# mkdir -p /u01/app/grid

[root@OEL7 ~]# mkdir -p/u01/app/11.2.0/grid

[root@OEL7 ~]# chown -R grid:oinstall /u01

Create directories for oracle database installation.

We have to assign oracle user to asmdba group in order to all oracle user to discover ASM disks during database creation. oper group will be used by oracle software.

Now create login script for oracle and grid user

Login Script for oracle user:

[root@OEL7 ~]# su - oracle
[oracle@OEL7 ~]$ echo > .bash_profile
[oracle@OEL7 ~]$ vi .bash_profile

Copy and paste following and save the .bash_profile. You may skip lines in red color

Set resource limits for Oracle software installation

To improve the performance of the software on Linux systems, you must increase the following resource limits for the Oracle software owner users ( grid).

For oracle user it has been automatically setup by the oracle-validated tool.

To make these changes, run the following as root:

Add the following lines to the /etc/security/limits.conf file

[root@OEL7 ~]# vi /etc/security/limits.conf

Enter following line at the end of file.

grid soft nproc 2047 grid hard nproc 16384 grid soft nofile 1024 grid hard nofile 65536

Add or edit the following line in the /etc/pam.d/login file, if it does not exist:

[root@OEL7 ~]# cat >> /etc/pam.d/login <<EOF

> session required pam_limits.so

> EOF

Add the following lines to the /etc/profile file by running the following command:

[root@OEL7 ~]# cat >> /etc/profile <<EOF

> if [ \$USER = "oracle" ] || [ \$USER = "grid"] ; then

> if [ \$SHELL = "/bin/ksh" ]; then

> ulimit -p 16384

> ulimit -n 65536

> else

> ulimit -u 16384 -n 65536

> fi

> umask 022

> fi

> EOF

Install oracle ASM package and create ASM disk groups:

Check if oracleasm-support package is installed or not by running following command
rpm -qa | grep oracleasm
If installed then go with Next step to install oracleasmlib, otherwise install it

One more package we need to install is oracleasmlib-2.0.12-1.el7.x86_64.rpm. Download it from this link and install

Configure and load ASM kernel module as root user

The script completes the following:

Creates the /etc/sysconfig/oracleasm configuration file
Creates the /dev/oracleasm mount point

Enter Following lines to load the Oracle ASM kernel module

[root@oel7 ~]# /usr/sbin/oracleasm init

This will load the oracleasm module

Now Create Oracle ASM Disk Volumes, Check the available disks

We have three disks available for ASM. Now we have to create partitions to be able to use those partitions as ASM disks.

Reboot the system to apply the changes. To List ASM disk run following.

Test disk discovery

Now we have to install Oracle Grid Infrastructure, login as grid user browse the path up-to grid extracted folder and run the installer.

Before Running Root scripts we need to install Opath 18370031. If you have support account download the patch and install as grid_home Owner which is grid user.

ORACLE_HOME is grid users ORACLE_HOME and /home/Downloads is the directory where we extracted the patch 18370031

Open a new terminal window change the user to root and run the scripts.

Click OK after running Root Scripts and you will see.

At this moment we have Oracle ASM instance and related services up and running:

To verify the installation execute the following as user grid

Check sqlplus

Create ASM disk group for Oracle Database Installation (+FRA and +DATA)
As a grid user run asmca (ASM Configuration Assistant)

Now we have to install the Oracle database 11gR2. Logout and login with user root and change the password for user oracle as we didn't set the password for user oracle:

To set the password run following command
[root@oel7 ~] passwd oracle

Login with user oracle and extract the database archives. and you will see a folder database

You may face error like following.

Error in invoking target 'agent nmhs' of makefile '/u01/app/oracle/product/11.2.0.4/sysman/lib/ins_emagent.mk'.

Following is the work around for above error.

In /u01/app/oracle/product/11.2.0/db_1/sysman/lib/ins_emagent.mk
Look for the line $(MK_EMAGENT_NMECTL)

Change it to $(MK_EMAGENT_NMECTL) -lnnz11

Click Retry and Setup will continue.

Oracle Database 11gR2 software has been installed successfully. Now we have to create the database using dbca with user oracle.

[oracle@oel7 ~]$ dbca &
