Oracle Linux 7.9 Installation On Virtual Box

In the previous section of this blog series, we explored the installation process of Oracle Virtual Box on a Windows operating system.

Now, we will shift our focus towards preparing a virtual machine for the installation of Oracle Linux.

To accomplish this, we will follow a set of steps to adequately configure the virtual machine. These steps can be utilized to create any virtual machine, with the exception of allocating the appropriate amount of RAM and hard disk space based on specific requirements.

In this case, as we are installing Oracle Apps R12.2.12, we have adjusted the resources such as RAM and hard disk space accordingly to ensure optimal performance during the installation process.

Open Virtual Box And Click New ICON. It will open a Pop Up Box on which Enter the Details of the Following Name: {Name of the Desired VM} Folder: {Folder location where you need to Create the VM] ISO Image: {ISO File of OEL 7.9} Also, Click the Check Box of “Skip Unattended Installation” Now Click NEXT
Now Enter the Following Details: Base Memory: {16GB} (As I have Mentioned Before I will configure it on 16gb which is Recommended) Processors: {4} Now Click Next
Now in this Step, we will Create a Virtual Hard Disk. As mentioned Before I will be allocating 250 GB size to this disk for Operating System and Staging Area. Note: If you have a Limitation of Space you can allocate 110 GB for this Hard Disk. After this Click Next and Then Click Finish to Create a Virtual Machine for Further Configuration
As I have to Install Oracle Apps R12.2.12  in this Linux Virtual Machine, I will add an additional 300 GB Hard Disk for the Application File System and Database. So for adding one more Hard Disk, we will go in the Settings of the created Virtual Machine by Clicking Settings of this Virtual  Machine.
Once The Settings Box opens, go to the Storage TAB and Click on + Hard Disk Button as shown in the Picture.
Now Click Create Button to Open a Virtual Hard Disk Creation Wizard
Click Next
Click Next
After Entering the Desired Value of the Hard Disk to Be Created, then Click Finish
Now as You Can See the Drive that we created in Above Steps is in “Not Attached” Condition. Click This “Hard Disk”  and Click “Choose” as Shown In the Picture Below
As you can see we are Having 2 Hard Disks in this Virtual Machine that we Created. Click OK to Continue Further
Now Start the Newly Configure VM to Install the OEL 7.9
Now New Window Will Pop Up Running the Installer for OEL 7.9.  Click in this Window and select “Install Oracle  Linux 7.9” with arrow keys on the keyboard and Press ENTER.

Now We will Install the Virtual Box Guest Addition RPM. For This Insert the Guest Additions CD Image as shown in the Picture
Click Run
Enter The Password of the user to continue the Installation Process
Click Enter to Close the Window. Reboot After the installation.
Configure Another Virtual Hard Disk Process
As a reminder, during the Linux configuration on Virtual Box, we included two virtual hard disks. However, during the Linux installation process, we only configured one of the virtual hard disks. Now, it is time to configure the remaining virtual hard disk. To display the available disks, open the terminal as the root user and enter the command “fdisk -l”. This will provide a list of the disks that are currently accessible.

Step 1: Format Disk To Create File System

Step 2. Create and Mount File System

Following a successful installation of Linux on Virtual Box, we can now proceed with configuring the RPM packages on the Linux system based on the specific software you intend to install.

AutoPatch error: The worker should not have status ‘Running’ or ‘Restarted’ at this point.

ERROR:

R12.2 ADOP:

AutoPatch error:
The worker should not have status ‘Running’ or ‘Restarted’ at this point.

CAUSE:

SOLUTION:

Step 1: Launch Adctrl and check the status of the workers. Are the workers currently running or have they been started?

Select the following options in Adctrl: 
   Option 1 to Show Worker Status then
   Option 4 to Tell manager that a worker failed its job

Step 2. Restart the ADOP patch from the following given OPTIONS.

• If you wish to restart a failed patch from the beginning, specify the following option

• If you wish to restart a failed patch from where it left off, simply specify the following option

adop phase=apply patches=<Patch_Number> restart=yes abandon=no

OPMNCTL startall Fails with unexpected exit: status 4200

FIX:

Once the new wallet is in place, OPMN and OHS should be able to initiate successfully.

To verify the startup of only OPMN and OHS, you can utilize the commands adopmnctl.sh start and adapcctl.sh start.

Alternatively, you have the option to execute adstrtal.sh, which will attempt to start all components simultaneously.

Steps to change password for APPS in EBS R12.2

Today, we will delve into the process of changing the EBS APPS password in Oracle E-Business Suite R12.2. While this is a routine and fundamental task for every appsdba, it is essential to perform the steps cautiously to avoid any potential risks or unforeseen complications.

What is the Apps Schema?

The Apps schema refers to a schema that does not contain any tables of its own. It serves as the shared runtime schema for all E-Business Suite products. It includes synonyms for all tables in Oracle apps and also consists of packages, functions, and procedures. The default password for this schema is “apps.”

What is the Applsys Schema?

The Applsys schema comprises all the necessary tables for administrative purposes. The default password for this schema is also “apps.” It consolidates the database objects of various technical products into a single schema called Applsys.

What is the Applsyspub Schema?

The Applsyspub schema primarily handles password checking. Its default password is “pub.” Applsyspub is utilized for authentication through read-only views.

Why should the Apps and Applsys passwords always be the same?

The requirement for having the same password for both the Apps and Applsys schemas is due to the authentication process. When signing on to Apps, it initially connects to a public schema named APPLSYSPUB. This schema validates the AOL username and password entered, typically using the guest user account (operations/welcome). Once this authentication is confirmed, selecting a responsibility triggers validation by the APPLSYS schema, followed by the connection to the APPS schema.

Step 7: Modifying the Password in WebLogic

A) If your EBS R12.2 AD TXK Delta is 7 or higher, you should follow the subsequent steps.

[applmgr@ebslive scripts] $perl $FND_TOP/patch/115/bin/txkManageDBConnectionPool.pl
Please select from list of valid options
        updateDSPassword - Update WebLogic Datasource Password
        updateDSJdbcUrl  - Update WebLogic Datasource Connection String
Enter Your Choice : updateDSPassword
Enter the full path of Applications Context File [DEFAULT -]:
Enter weblogic admin server password: <enter Weblogic Password>
Enter the APPS user password: <enter New APPS Password>

B) If your EBS R12.2 AD TXK Delta is lower than 7, you should utilize the following steps.

1. Access the WebLogic console through a web browser.
2. Click on the “Lock and Edit” button.
3. Navigate to the “Domain structure” section and select “Services” -> “Data Sources.”
4. Locate and select the “EBSDataSource” entry.
5. In the “Settings of EBSDataSource” page, go to the connection pool section.
6. Enter the updated password for the apps user and save the changes.
7. Finally, click on “Activate changes” to apply the modifications.

Step 8 . Start the application services.

[applmgr@ebslive appl]$ pwd

  /u01/app/PROD/fs2/EBSapps/appl

[applmgr@ebslive appl]$ adstrtal.sh

 You are running adstrtal.sh version 120.24.12020000.6

 Enter the APPS username: apps 

 Enter the APPS password:

 Enter the WebLogic Server password:

 All enabled services for this node are started.

 adstrtal.sh: Exiting with status 0

Step 9: Validate WLS Datastore Modifications by Following These Steps

1. Access the WLS Administration Console and log in.
2. In the Domain Structure tree, expand the “Services” section, then choose “Data Sources.”
3. Locate and select “EBSDataSource” on the “Summary of JDBC Data Sources” page.
4. Navigate to the “Settings for EBSDataSource” page and select “Monitoring” followed by “Testing.”
5. Select “oacore_server1” from the available options.
6. Click on “Test DataSource.”
7. Look for the confirmation message stating “Test of EBSDataSource on server oacore_server1 was successful.”
8. If Integrated SOA Gateway (ISG) is implemented, repeat the steps for “OAEADataSource”. Verify “oafm_cluster*” managed servers are started successfully.
