With latest versions of AutoUpgrade, downloading and installing Oracle AI Database 26ai on Linux x86 on-premise has become a very simple process. If you want to give a try to Oracle Database 26ai, building a test environment requires minimal effort as you will see in this short post.

What we need:

Internet access
Oracle Support account
new installation of Oracle Linux 8 or 9, RHEL 8 or 9, SLES 15 with enough space for Oracle binaries
Java JDK 8 to JDK 11
latest version of AutoUpgrade

Steps to proceed:

update the system if not already performed
install OpenJDK if java not yet installed on the system
install Oracle preinstall package for 26ai
create oracle base, inventory and home directories with relevant permissions
change to oracle user created during installation of preinstall package for 26ai
create AutoUpgrade home with some subdirectories
download latest AutoUgrade version
check version of AutoUpgrade
create AutoUpgrade configuration file for software download
configure AutoUpgrade keystore to enable access to Oracle Support
launch software download
create AutoUpgrade configuration file for Oracle Home creation
launch Oracle Home creation
check the newly installed Oracle AI Database 26ai environment

1) Update the system

sudo dnf update

2) Install OpenJDK if java not yet installed on the system

sudo dnf install -y java-11-openjdk

3) Install Oracle preinstall package for 26ai

sudo dnf install -y oracle-database-preinstall-23ai

4) Create oracle base, inventory and home directories with relevant permissions

sudo mkdir -p /u01/app/oracle
sudo mkdir -p /u01/app/oraInventory
sudo mkdir -p /u01/app/oracle/product/23.26.2/dbhome_1
sudo chown -R oracle:oinstall /u01/app/oracle
sudo chown -R oracle:oinstall /u01/app/oraInventory

5) Change to oracle user created during installation of preinstall package for 26ai

sudo su - oracle

6) Create AutoUpgrade home with some subdirectories

mkdir autoupgrade
mkdir autoupgrade/logs
mkdir autoupgrade/patches
mkdir autoupgrade/keystore
mkdir autoupgrade/etc
cd autoupgrade

7) Download latest version of AutoUpgrade

wget -O /home/oracle/autoupgrade/autoupgrade.jar https://download.oracle.com/otn-pub/otn_software/autoupgrade.jar

8) Check version of AutoUpgrade

java -jar autoupgrade.jar -version

9) Create AutoUpgrade configuration file for software download

vi etc/au-download.cfg

global.global_log_dir=/home/oracle/autoupgrade/logs
global.keystore=/home/oracle/autoupgrade/keystore

dl.folder=/home/oracle/autoupgrade/patches
dl.patch=RU,OPATCH
dl.target_version=23
dl.platform=LINUX.X64

10) Configure AutoUpgrade keystore to enable access to Oracle Support

java -jar autoupgrade.jar -config etc/au-download.cfg -patch -load_password
Processing config file ...

Starting AutoUpgrade Patching Password Loader - Type help for available options
Creating new AutoUpgrade Patching keystore - Password required
Enter password:
Enter password again:
AutoUpgrade Patching keystore was successfully created

MOS> add -user <your-mos-account-name>
Enter your secret/Password:
Re-enter your secret/Password:
MOS> save
Convert the AutoUpgrade Patching keystore to auto-login [YES|NO] ? YES
MOS> exit

AutoUpgrade Patching Password Loader finished - Exiting AutoUpgrade Patching

11) Launch software download

java -jar autoupgrade.jar -config etc/au-download.cfg -patch -mode download
AutoUpgrade Patching 26.3.260401 launched with default internal options
Processing config file ...
Loading AutoUpgrade Patching keystore
AutoUpgrade Patching keystore is loaded

DATABASE RELEASE UPDATE 23.26.2.0.0
    File: p39099680_230000_Linux-x86-64.zip \ 16%
...

After download has completed, we get the following output:

AutoUpgrade Patching 26.3.260401 launched with default internal options
Processing config file ...

AutoUpgrade Patching keystore is loaded

-----------------------------------------------------

At time of writing, 23.26.2 was just released and Data Pump Bundle Patch could not yet be downloaded for this Release Update.

12) Create AutoUpgrade configuration file for Oracle Home creation

vi etc/au-create-home.cfg

global.global_log_dir=/home/oracle/autoupgrade/logs

crh.folder=/home/oracle/autoupgrade/patches
crh.patch=RU,OPATCH
crh.target_version=23

crh.home_settings.edition=ee
crh.home_settings.oracle_base=/u01/app/oracle
crh.home_settings.inventory_location=/u01/app/oraInventory
crh.download=no

13) Launch Oracle Home creation

java -jar autoupgrade.jar -config etc/au-create-home.cfg -patch -mode create_home
AutoUpgrade Patching 26.3.260401 launched with default internal options
Processing config file ...
