To overwrite an installation of Application Server in the same directory of the same computer where Application Server is installed, start the Program Product Installer from the provided media of the product, and then select the program that you want to install from the program product installation window.

Prerequisites

The system engineer has root privileges (super user).
A prerequisite operating system (OS) and patches are installed.
An Application Server with the same version as the Application Server to be updated is already installed.
The system that uses the Application Server to be updated has been stopped.

System engineers

Procedure

If a server or domain is running on the installed Application Server, do the following to stop that server or domain:
1. To stop the Application Servers, run the stop-servers subcommand of the asadmin utility command.
```
asadmin stop-servers
```
  When this command is run, the result is displayed as follows:
```
Command stop-servers executed successfully.
```
2. To stop a domain, run the stop-domain subcommand of the asadmin utility command.
```
asadmin stop-domain domain_name
```
  When this command is run, the result is displayed as follows:
```
Command stop-domain executed successfully.
```
3. To display the list of domains, run the list-domains subcommand of the asadmin utility command.
```
asadmin list-domains
```
  When this command is run, the result is displayed as follows:
```
Name: domain1 Status: not running
Name: domain_name Status: not running
Command list-domains executed successfully.
```
  Make sure that the statuses of the stopped domains are not running.
Insert the provided media of the product into the corresponding drive.
Run the mount command to mount the file system of the corresponding media.
In Linux, use the following code:
```
mount -r -o mode=0544 /dev/cdrom 
mount_directory_name_of_filesystem_for_corresponding_media
```
Note that special_file_name_of_device and mount_directory_name_of_filesystem_for_corresponding_media vary depending on the operating system (OS), hardware, and environment.
Start the setup program from the media of the product.
In Linux, use the following code:
```
mount_directory_name_of_filesystem_for_corresponding/x64lin/setup -m 
mount_directory_name_of_filesystem_for_corresponding_media
```
Important note

The details of the directory name and file name of the corresponding media and how to view this information, might differ depending on the computer environment. Use the ls command to verify this information, and enter the displayed file name as is.
