Install EBS R12.2 on Linux 7

by mn.sobieh August 13, 2020

This article explains how to install Oracle EBS R12.2 on Linux 7 step by step. In addition, It provides the instruction to configure your OS. So, EBS installation complete in a single straight shot and avoids errors in your installation.

Oracle EBusness Suite (#EBS) installation is a lengthy one, because of the installation process validation, and install Database, Middleware. Though, Oracle University Installer (OUI) made the Installation a bit straight forward. However, Its validation takes a lot of time before it shows any error messages. therefore, follow the pre-installation configuration mentioned below to get a smooth installation.

Before we start there are few assumptions, like:

Your server has enough free space at least 300GB.
I will use /u01 as a base of operations, for example, it holds source zip files, extracted stage folders, and installation files too.
Source files are located in /u01/src

EBS prerequisites for a successful install.

The following configurations are essential for EBS R12.2 installation success. therefore, Execute the following commands with a privileged user.

1. Server hostname.

Make sure that your server hostname is stored in the hosts file in the proper syntax

<IP-Address>     <hostname.domainname>        <HOSTNAME>
192.168.0.50     ebssrv1.cloudadmin.club       ebssrv1

2. Oracle Linux preinstall Packages

Then, Update your operating system and Install Oracle pre-installation configuration packages for both database and EBS. each package fulfill the prerequisites of one of the components.

[root@ebssrv1 ~]# yum update -y
[root@ebssrv1 ~]# yum install -y oracle-database-server-12cR2-preinstall.x86_64
[root@ebssrv1 ~]# yum install -y oracle-ebs-server-R12-preinstall.x86_64

This installation will create the oracle user and all required groups oinstall, hence, you need to set a password for the oracle user.

3. Oracle Inventory file

It’s essential to creat and configure Oracle inventory file correctly. If not, It will cause your installation to fail, as, the EBS R12.2.5 wizard will try to access /oracle/oraInventory which does not exist. therefore, let’s create it in /etc/ with name oraInst.loc

the file should have the following lines:

[root@ebssrv1 ~]# cat /etc/oraInst.loc
inventory_loc=/u01/oraInventory
inst_group=oinstall

4. File system fold structure

To Install Oracle EBS you need 3 directories, that is to say,

Source directory: It contains the Zip files that you downloaded from Oracle.
Stage directory: Contains the extract of zip files in structure needed by the installer.
EBS Installation Directory: that contains the running instance and datafiles.

Oracle Base directory

Create /u01 and change ownership

[root@ebssrv1 ~]# mkdir /u01
[root@ebssrv1 ~]# chown -R oracle:oinstall /u01

5. Configure Linux Firewall

Oracle EBS needs a group of ports, So the following command enables access to its default ports. I intentionally didn’t add the database listener to prevent external access to the database.

You can adjust the ports to the values

[root@ebssrv1 ~]# firewall-cmd --permanent --zone=public --add-port={7001/tcp,7201/tcp,7401/tcp,7601/tcp,7801/tcp,8889/tcp,9999/tcp,8000/tcp}
success
[root@ebssrv1 ~]# firewall-cmd --permanent --zone=public --add-port={7002/tcp,7202/tcp,7402/tcp,7602/tcp,7802/tcp,8890/tcp,10000/tcp}
success
[root@ebssrv1 ~]# firewall-cmd --reload
success

Build Oracle EBS R12.2 stage.

To prepare for EBS installation, navigate into Source folder ( /u01/src), then extract StartCD compressed files

cd /u01/src
unzip V100052-01_1of3.zip
unzip V100052-01_2of3.zip
unzip V100052-01_3of3.zip

It will extract the content into a directory called startCD.

Next, Navigate into /u01/src/startCD/Disk1/rapidwiz, then execute buildStage.sh script.

This interactive script will give you the option to create the staging directory structure and extract the ZIP files into it, consequently, we will be able to start the installation
To build stage structure I will ask to provide the EBS source directory

[root@ebssrv1 ~]# cd /u01/src/startCD/Disk1/rapidwiz/bin
[root@ebssrv1 bin]# ./buildStage.sh

After application starts, The interactive Configuration menu will prompt you for your input.

Firstly, press Enter to open the Build stage menu, Next, Press (1) to create a new stage area for your ebs installation.

Next, press 2 to select Linux as a platform

Finally, specify the directory that contains the zipped installation files, in our example the files stored in /u01/src/zipFiles. Then press Enter.

Follow the procedures mostly It is informational, as the script will verify the files, then extract them, after that, it will apply patches, and finally, it will Exit.

How to install EBS R12.2.

This article’s objective is to ensure a successful install of Oracle ebs R12.2 on your Oracle Linux 7 server. therefore, We will not discuss advanced Installation.

To start the installation. First, Navigate to oracle EBS rapid installer to start to install oracle EBS.

[root@ebssrv1 ~]# cd /u01/src/startCD/Disk1/rapidwiz/
[root@ebssrv1 rapidwiz]# ./rapidwiz

When the Wizard UI opens,Check use Express Install then press Next.

Nex, You will be asked to enter the following values

Database type: whether your installation has demo data or clean installation.
Enter Database SID : VIS
Domain: Enter the domain that your server belongs to, As explained in EBS R12.2 prerequisites section. For example, our domain is cloudadmin.club the wizard will attach hostname.
Oracle FusionMiddleware credentials (username-password)
Oracle Base Dir: make sure you have the correct path /u01.

When you press Next. the wizard will issue system check

If you applied the configuration correctly, The results should appear like this image.

Now, press Next to proceed with the installation, press Next then Next.

When the installation finishes It will show you the post-installation validation.

The previous screen shows a successful post-installation check for your installation. press Next will show the finish screen.

After your installation is complete. Click on the “Connect to oracle e-bussiness suite release 12.2” button, or open your EBS URL in our example: http://ebssrv1.cloudadmin.club:8000 to get the EBS login page.

Access your EBS using default username sysadmin and password sysadmin too.

Our conclusion that the Install process of Oracle EBusiness Suite (EBS) is a time consuming, especially when you repeat the process because EBS R12.2 prerequisites on Linux were not fulfilled. If you properly configured your operating system and followed the instructions in this article you will save your time and get it done from the first time.

Start EBS R12.2 on Linux

by mn.sobieh August 9, 2020

If you are new to Oracle E-Business suite R12.2 on Linux, You might find stating EBS instance a bit confusing especially after rebooting your server. If you try to execute adstrtal.sh script directly, It will fail. As there are some preparations If that is your case then, this article is for you. It explains how to safely stop and start oracle EBS processes on Linux. For information on how to install EBS R12.2 on Linux Server.

Production environments host their database runs on a separate server. For that, EBS R12.2 does not include starting the database in their start script, even if it is hosted on the same server.

There are two phases to start oracle E-Business suite R12.2 on Linux.

First Phase: start EBS database.

Second Phase: Find start Script and start EBS instance.

Start EBS database

Starting EBS database is a bit different than starting a normal Oracle database. First, you need to identify ebs database’s home.

Get server name is simple just execute the following command.

$ tree -d -L 2 /u01

The output depends on your Oracle Base directory, for example, It shows oracle home bellow the VIS directory.

Next, we will load database environment variables.

[oracle@ebssrv1 ~]$ ls -l /u01/VIS/12.1.0/*.env
-rw-r--r--. 1 oracle oinstall 4205 Aug 8 09:15 /u01/VIS/12.1.0/VIS_ebssrv1.env
[oracle@ebssrv1 ~]$ source /u01/VIS/12.1.0/VIS_ebssrv1.env

Finally, Start the database and the database listener. By executing the following commands.

[oracle@ebssrv1 ~]$ lsnrctl start
[oracle@ebssrv1 ~]$ echo "startup" | sqlplus -s / as sysdba

The output of the command will look like that:

Start Oracle EBS Instance using adstrtal.sh

After Starting EBS database, Next is to start The E-Business suite R12.2 process. Simply execute adstrtal.sh from EBS administrator script directory.

Default Path for the script in /u01/VIS/fs1/inst/apps/VIS_ebs/admin/scripts

To execute a shell script in Linux or UNIX from the same directory which the script located is simple. You just need to add ./ before the script’s name. For example, in our situation to execute the adstrtal.sh script.

[oracle@ebssrv1 ~]$ cd /u01/VIS/fs1/inst/apps/VIS_ebs/admin/scripts
[oracle@ebssrv1 ~]$ ./adstrtal.sh

when you execute the script, it will ask you to provide three credentials Apps username, APPS password, and Weblogic Password.

Note: EBS R12.2 APPS default username is apps and the password is apps too.

You could provide username and password for apps as parameters for adstart.sh script as follows:

[oracle@ebssrv1 ~]$ ./adstrtal.sh apps/apps

It’s not recommended to do so. besides, it will ask for WebLogic Server password.

Stop Oracle EBS R12.2

To achieve safe shutdown of ebs services, you need to reverse the order of the process.

stop Oracle EBS instance

First, stop ebs R12.2 instance using the adstpall.sh script which is located in EBS admin scripts directory.

After executing it, it will ask for the Apps user credentials and WebLogic Server password.

[oracle@ebssrv1 ~]$ /u01/VIS/fs1/inst/apps/VIS_ebssrv1/admin/scripts/adstpall.sh

Stop the ebs database.

To stop the ebs database, first, load the environment variables. Then, shut down the database and the listener.

To summarize, You need to start the database before you start ebs, If you executed the adstrtal.sh script without starting the database, It will fail. consequentially, you will need to restart your server. First Start your database, then, execute the script.

list open ports using netstat

by mn.sobieh August 7, 2020

netstat is an essential tool for network issues diagnoses. for example, It prints OS network connections and list open ports, routing tables, interface statistics, masquerade connections. netstat comes in most Operating systems like Windows and Linux. however, in recent Linux releases it was superseded by other commands like ss and “IP” commands. Though, to unlock its full potentials, you have to use its parameter. in this article explain

netstat parameters

Admins usually use netstat to check specific things. therefore, they use its parameters to achieve that. however, if you execute netstat command without any parameters, it will print all active connections. keep in mind that ss command has replaced netstat without any parameter.

You can get all available parameters by typing –help or visit netstat manual, Instead, I will talk about the useful combination of parameters that comes with netstat. for that, the following table show number of parameter:

–listening	-l	listen
–numeric	-n	numbers instead hostnames and service description
–program	-p	list program connecting on that port
–tcp	-t	TCP ports only
–udp	-u	UDP ports only
–version	-V	show netstat version
–route	-r	list routing table, the command ip route replaces it

netstat list open ports on Linux.

To print Active ports that are listening to connections, in addition to the application responsible for opening the ports and their PID.

# netstat -lnp

Bellow, The output in order, the protocol, Recv-q, Send-Q, the Local listening port & Address, connected foreign port & address, the state of the port, and finally Process ID and Program name.

netstat-lnp output

besides, You pipe netstat output into other commands like grep, egrep, or awk to filter the output. and search for a specific port or application.

to view information about a specific open port:

# netstat -lnp | grep ":<port number>"

The view information about a specific application and list the ports related to it.

# netstat -lnp | grep "<application Name>"

scan open ports using nmap tool.

Nmap is a port security network scanner. hence, it helps you to check servers’ firewall settings and security configurations. For example, to scan for open ports for specific server IP and list open ports

nmap –p– <Server IP>

To conclude, many applications open ports to communicate with remote resources. hence, to list the applications that are opening ports and listening for remote requests. For that, we used netstat that comes with Linux and windows to list the ports.

manually configure network in OEL 7, CentOS 7

by mn.sobieh August 5, 2020

When you install CentOS, RHEL, or OEL with graphical Interface, it comes with NetworkManager. The NetworkManager daemon maks networking configuration and operation easy and automatic as possible by managing network interfaces, either Ethernet, WiFi, or Mobile Broadband devices. Besides, NetworkManager provides a rich API to control network settings and operations. However, when configuring servers It’s preferable to have their networking settings to be consistent. therefore, This article explains how to disable NetworkManager, hence, configure the network and set IP ethernet manually.

The following steps are suitable for versions 6 and 7 of RHEL, OEL, and CentOS.

Firstly, Identify which card you want to configure by executing the ifconfig command with parameter -s to shortlist the output.

[root@s59 ~]# ifconfig -s
Iface    MTU    RX-OK RX-ERR RX-DRP RX-OVR    TX-OK TX-ERR TX-DRP TX-OVR Flg 
eno1     1500  4596894    0   5617 0        41057    0      0      0 BMRU 
lo       65536     440    0      0 0        440      0      0      0 LRU 
virbr0   1500        0    0      0 0          0      0      0      0 BMU 
[root@s59 ~]#

In view of the output of our example, you can see that the server has three network interfaces, as follow:

eno1	LAN Network interface
lo	Loopback interface
virbr0	Wireless Network interface

In our case, LAN Interface eno1 is our target.

Disable NetworkManager

Firstly, Stop NetworkManager by stopping its service.

systemctl stop NetworkManager.service

Secondly, disable Network Manager using the following command.

systemctl disable NetworkManager.service

manually configure network setting.

Initially, navigate into the network configuration directory. then, edit the configuration file for the ethernet. For example, if the card name eno1 then the filename is ifcfg-eno1.

vi / etc/sysconfig/network-scripts/ifcfg-eno1

After that, add the following parameters in the file if they are not exist

ONBOOT=yes 
NM_CONTROLLED=no 
BOOTPROTO=none 
IPADDR=XXX.XXX.XXX.XXX
NETMASK=255.255.255.0
# you can use PREFIX=24 instead of NETMASK=255.255.255.0
GATEWAY=<GATE WAY IP XXX.XXX.XXX.XXX>

manually configure network in OEL 7, CentOS 7 - ifcfg-eno1

Optional you can add the following lines to force DNS on specific Card

 DNS1=<DNS IP XXX.XXX.XXX.XXX>                
 DNS2=<DNS IP XXX.XXX.XXX.XXX>

Manually configure DNS resolve file.

make sure it has a reliable DNS IPs, for example, google public DNS 8.8.8.8

 vi /etc/resolv.conf  
 nameserver 8.8.8.8

manually configure network in OEL 7, CentOS 7 - resolv

Finally, type :wq to save & exit the editor.

Restart network services

For version 6, use the service command.

# Service restart network

On RHEL 7 use systemD command, though, executing the above command will redirect to systemD command

# systemctl restart network.service

xm destroy – restore vanished vms

by mn.sobieh July 29, 2020

this article addresses a common issue that happens when you use xm destroy command. Hence it will show how to solve this issue and restore vanished VMs.

What is XM?

xm command is a program that allows you to manage Xen virtualization guest virtual machines. In other words, This program can list, create, pause, and shutdown VMs. in addition, it controls the machine’s virtual block devices. though it’s very powerful, it does not handle error checking or configuration file errors very well and mistakes can lead to system instability or errors in virtual machines. Therefore, in future you should use virsh or virt-manager commands instead.

I was taking a course one of the tasks is to crash the server which runs the services. I applied the command to crash the VM

Linux XM command explained.

To take any action on XEN based virtual machines using xe command. generally, you need to add a parameter and define your target virtual machine.

xm <options>  <Target>

XM options

`xm list`	List active virtual machines
`xm create [-c] vmName/ID`	Start a virtual machine. If the -c option is used, the start up process will attach to the guest’s console.
`xm consolevmName/ID`	Open a virtual machine’s console
`xm destroy vmName /ID`	Force a virtual machine to power off.
`xm reboot vmName /ID`	Reboot a virtual machine, runs through the normal system shut down and start up process.
`xm shutdown vmName /ID`	Shut down a virtual machine, runs a normal system shut down procedure.
`xm pause`	Pause virtual machine
`xm unpause`	Resume virtual machine
`xm start vmName`	Start powered off virtual machines

problem xm destroy hide VMs, how to solve it ? .

It happens, that when you execute xm start command, it returns an error that there is no machine with that name, apparently, xm destroy hide the VM as if it’s deleted. moreover, When you list the available machines using xm –list. the machine does not show in the list.

The solution is to find where the config files of that VM. then, create a new virtual machine or rather I registered it again by executing

cd /location/of/vmFiles
xm create <virtName.conf>

the result of this command creates a new instance of the virtual machine using its existing configuration files and registers it again. and by that, you will be able to restore that vanished vm

vi text editor basics – P1

by mn.sobieh July 23, 2020

If you deal with recent versions of Linux you might use an enhanced version of improved vi text editor vim. it has a lot of improvement. however, This article focus on the original vi that is found in UNIX machines. So, we will discuss how to use the Linux vi text editor. in addition, explain vi mechanism. if you already know how it works, then you might want to read its man pages.

vi a powerful text editor.

once you know vi, you can edit files really quickly, as it is extremely economical with the keystrokes. Due to its different modes for inserting and issuing commands, it is much faster than most non-mode based editors. also, It is a very small editor. nevertheless, it can do almost anything, as long as you know how to get it to do what you want

The 3 Modes of VI

The first thing most users learn about the VI editor is that it has three modes command, insert, and execute.

1 – Command Mode

allows the entry of commands to manipulate text. for example, copy, delete, past, cut …etc.. These commands are usually one or two characters long and can be entered with few keystrokes.

2 – Edit Mode (vi Insert mode).

puts anything typed on the keyboard into the current file. in other words, act like a normal text editor and insert text …etc

3 – vi Execute Mode

Commands Used to do multiple operations. for example, save files, quite the editor, search file content, or open a file … etc.

Switch vi modes

into insert mode

VI starts out in command mode. There are several ways to switch vi mode to insert mode and add texts.

The most commonly used command to get into insert mode is by pressing on the letter a or letter i. These two commands are described below.

Get back to command mode

Most commands are one character long, including those which use control characters. Once you are in insert mode, you get out of it and return to command mode by pressing the escape key. If your terminal does not have an escape key, ^[ should work ( control + [ ). basically, You can hit escape twice in a row and VI would definitely return to command mode.

Hitting escape while you are already in command mode doesn’t take the editor out of command mode. It may beep to tell you that you are already in that mode.

Save and Exist vi, here an example,

– to switch to vi execute mode, firstly, you must be in command mode. then, press or type Colon “:“. after that, add the letter related to command to be executed. for example

to save the changes, type :w then press enter.

to quite without saving type :q! then press enter.

So, If I want to save my changes and close the editor. I will follow these steps

Press escape twice to make sure that I am in command mode.
Type colon : and wq .so the final look is “:wq”.

Conclusion, vi Linux editor is a powerful tool. hence, as an administrator, you should know vi editor basics.

vmhgfs-fuse mount error [solved]

by mn.sobieh July 19, 2020

vmhgfs-fuse is part of open-vm-tools. open-vm-tools comes with major Linux distributions. this article shows you how to use it and fix vmhgfs-fuse mount errors. like:

Error -107 cannot open connection

You can find more information about the difference between vmware-tools and open-vm-tools. Also, for in-depth information read VMware documentation.

Install open-vm-tools

for RPM-based Linx like RHEL, centOS, Oracle, and fedora. execute the following command:

yum install -y open-vm-tools or  dnf  install -y open-vm-tools

for Debian, ubuntu.

apt-get install -y open-vm-tools

Mount vmhgfs-fuse file system

Temporary mount.

To access to the host’s shared folders from your guest operation system by using the open-vm-tools. You need to mount a vmhgfs-fuse block device.

Just execute the following command.

mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other

This command allows temporary access to the host’s shared folder, however, you’ll need to execute it every time you restart your virtual machine.

Persistent mount.

We will make OS mount vmhgfs-fuse shard-folders on its startup, Thus, Edit /etc/fstab file with your favorite editor, then append the following entry to the end of the file.

.host:/     /mnt/hgfs     fuse.vmhgfs-fuse      allow_other      0 0

or execute the following command.

echo ".host:/     /mnt/hgfs     fuse.vmhgfs-fuse     allow_other     0 0 " >> /etc/fstab

if you want to read more about fstab mount options, I mentioned a few while explaining how to mount ntfs partitions in linux

Let’s get rid of

To unmount the host’s shared-folders. follow these steps to avoid any future errors in your virtual machine.

first, umount the shared folder

umount /mnt/hgfs

then, comment the line in /etc/fstab which vmhgfs-fuse word. by adding a # in the line beginning.

Finally, remove the shared from the virtual machine’s settings page. this process will fix vmhgfs-fuse mount error in any new cloned virtual machine.

Fix vmhgfs-fuse mount error.

mount errors happen usually when you clone a machine you previously configured the vmhgfs-fuse in it, or the machine has that entry into /etc/fstab, you’ll get an error and the system might not start. because the operating system tries to mount non-accessible resources ( host’s shared folders).

Solution :

If you faced this issue just do the following

Initially, power off your virtual machine.
after that, enable the shared-folder feature from the virtual machine’s setting. then add any drive/folder from your host.
Finally, start your virtual machine.

This will fix your issue with vmhgfs-fuse shared-folder and your machine will work without any complaints.

As to summarize, In this article we’ve found out how to how to install open-vm-tools, and mount vmhgfs-fuse file system. Also, how to remove the shared-folder, and solve vmhgfs-fuse mount error in Linux startup.

Compare vmware-tools vs open-vm-tools.

by mn.sobieh July 18, 2020

Any virtual machine hosted by VMware hypervisors needs a software called vmware-tools. It’s a suite of utilities that enhances its performance and improves the management of the virtual machine. VMware provides two packages vmware-tools and open-vm-tools. both provide the same features with a slight difference. for example:

open-vm-tools comes with Linux distributions, in contrast, VMware comes with the hypervisor.
vmware-tools requires a restart of the guest operating system. even more, It does not auto-updates.

In ESXi/vCenter :

If you use an open-vm-tools, you will find VMware tools status has value Guest Managed on VM’s Summary tab. This status means that vCenter Server to manage VMware Tools and you cannot use vSphere Update Manager to upgrade VMware Tools.

folders from myHost to the famous /mnt/hgfs directory. Though It is easy to do.

We used open-vm-tools and did troubleshooting related to vmhgfs-fuse mount errors.

mount NTFS partition on Linux in simple steps.

by mn.sobieh July 15, 2020

NTFS, NT File System, or New Technology File System is a file system that Microsoft invented. In other words, it is the default file system Windows NT family, that is to say, till Windows 2008 R2. Later Windows releases have ReFS beside it. This article will explain, by example, how to mount ntfs partition on Linux.

Why Linux can’t mount NTFS partitions?

Linux is free software work under GPL (GNU Public license). GPL grants permission to reuse or modify the source code to make derivative works, however, if you distribute your software, it requires you to license your derivative work under GPL too. that is to say, you have to make your code available to your users and allow them to further modify and redistribute it. Therefore, Linux can’t include any proprietary software, like graphic drivers or audio codecs.

To allow Linux to read and write files in NTFS partitions, It needs a driver ( ntfs-3g ) to recognize it. Fortunately, most Linux distributions include and use NTFS-3G by default. Next, we will explain the steps in three :

install the drivers.
mount NTFS partition.
Permanent mount NTFS.

Give it what it needs!

To Install ntfs-3g drivers. You need to enable a repository EPEL ( Extra Packages for Enterprise Linux ). If you don’t have it, then follow the instructions in these articles :

Install EPEL on CentOS.
Enable EPEL for Oracle Linux.

Next, Install driver packages by executing your Operating system counterpart command.

Enable ntfs-3g on CentOS 7 and OEL 7 .

yum -y install ntfs-3g ntfsprogs 
yum clean up

Enable ntfs-3g on CentOS 8 and OEL 8.

dnf -y install ntfs-3g ntfsprogs

Enable ntfs-3g on Ubuntu or Debian.

By executing the following command, you will give you OS the capability to mount NTFS partitions.

apt-get install ntfs-3g

Install ntfs-3g from source code.

For maximum stability use The ntfs-3g package which comes with your distributions. On the other hand, if it’s too old, you might want to compile the latest version from the source. If so, then follow these instructions.

make sure you have installed the basic development tools (gcc compiler, libc-dev libraries)

Download ntfs-3g latest version, then extract it, next, navigate into NTFS-3g directory.

wget https://tuxera.com/opensource/ntfs-3g_ntfsprogs-2017.3.23.tgz 
tar -xvf ntfs-3g_ntfsprogs-2017.3.23.tgz 
cd ntfs-3g_ntfsprogs-2017.3.23

Proceed with the compilation process. Initially, verify the compilation requirement.

./configure

Then, Compile the files

make

Finally, install the driver, thus distribute binary files into OS directories.

make install

if you aren’t root

sudo make install
