In case we want to mount a folder located in other partition, below steps can be followed.

Check the mount now.

[himanshu@ebs122 ~]$ df -aTh

In this post I am going to share steps to install Oracle Apps R12.2 in Google Cloud.

Server Preparation:

Google cloud VM creation with 500 GB storage and make sure host name length is small. I have used RHEL 6 image for Operation system.

VNC server installation- Refer link to check the steps

Once above tasks are done, we have to start with installation and pre-requisites.

1) I will install RPM's using oracle public repository.

cd /etc/yum.repos.d

Move all present repo files to backup directory.

mkdir bkp

mv * bkp/

Download oracle public repository repo file.

wget http://public-yum.oracle.com/public-yum-ol6.repo

Using a text editor, change the field ‘enabled=0’ to ‘enabled=1’ for the repositories corresponding to the machine’s operating system while also enabling the ‘addons’ channel. Here’s an example of a repo file’s entries:
[ol6_latest]

name=Oracle Linux $releasever Latest ($basearch)

baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/

gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6

gpgcheck=1

enabled=1

[ol6_addons]

name=Oracle Linux $releasever Add ons ($basearch)

baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/addons/$basearch/

gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6

gpgcheck=1

enabled=1

[ol6_UEK_latest]

name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch)

baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/

gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6

gpgcheck=1

enabled=1

2) Install the RPMS now using below command.

yum install oracle-ebs-server-R12-preinstall.x86_64

Once the pre-reqs are installed. We can verify the users.

Add appplmgr to dba group as well.

sudo fallocate -l 20G /u01/swapfile

sudo chmod 600 /u01/swapfile

sudo mkswap /u01/swapfile

sudo swapon /u01/swapfile

In Linux 7 use below in place of fallallocate

dd if=/dev/zero of=/swapfile bs=1024 count=20971520

edit /etc/fstab and add below

/u01/swapfile swap swap defaults 0 0

check available swap size.

5) Create /etc/oraInst.loc file and put below content in it.

Note: Make sure no space character are there in file content.

6) Setup ingress firewall rule for Google Cloud VM to enable connectivity to database port. I have decided to use port pool as 10 and 20, so my database port would be 1531(1521+10)

7) Map the hostname with Cloud external IP to be able to access.

In this post we are going to see how to attach a DISK on Google Cloud VM.

Steps:

3) Format the Disk

4) Mounting the DISK. Create a directory and mount the disk on that.

In this post we are going to see how can we setup GUI in google cloud VM using vncserver. I would be using the same for installing EBS R12.2 in future posts.

Steps:

1. Setup a VM on Google Cloud. I am using RHEL 6.

[himanshu@ebs122 ~]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.10 (Santiago)

2. Install the required RPMS

yum install tigervnc-server

yum install twm

yum install xterm

yum install xsetroot
yum install xclock

3. Start the VNC server using below command

[himanshu@ebs122 ~]$ vncserver

You will require a password to access your desktops.

Password:
Verify:
xauth:  file /home/himanshu/.Xauthority does not exist

New 'ebs122:1 (himanshu)' desktop is ebs122:1

Creating default startup script /home/himanshu/.vnc/xstartup
Starting applications specified in /home/himanshu/.vnc/xstartup
Log file is /home/himanshu/.vnc/ebs122:1.log

4. Now install any vnc viewer and try to access.
