Oracle 26ai Installation DB Creation

1. Download and Install Oracle Home/Oracle Software -> Download 26ai Oracle Software and Install:

- Oracle Software

- DB Software

- Oracle Home

- DB Home

a. Download DB software (26ai) from https://edelivery.oracle.com

- Oracle AI Database 23.26.1.0.0 for Linux x86-64

- DB - V1054592-01.zip

b. Install Oracle Software / DB software / Oracle Home / DB Home

- Copy DB SW from lapttop / Desktop to VM

- Use winscp

- Shared folder / NFS shared drive

- Directory creation & SW unzip

- mkdir -p /u01/app/oracle/product/26ai/dbhome_1

- unzip V1054592-01.zip -d /u01/app/oracle/product/26ai/dbhome_1

- yum install oracle* --skip-broken (It will set all kernel parameters and it will install all pre-requisite rpms and set all shared memory setting and create all oracle user & groups)

- yum -y install oracle-database-ee-19c

- yum -y install oracle-database-ee-21c

- yum -y oracle-ai-database-preinstall-26ai

https://docs.oracle.com/en/database/oracle/oracle-database

19C -> https://docs.oracle.com/en/database/oracle/oracle-database/19/ladbi/running-rpm-packages-to-install-oracle-database.html

26ai -> https://docs.oracle.com/en/database/oracle/oracle-database/26/ladbi/installing-the-oracle-preinstallation-rpm-with-uln-support.html

- Optional (In case if you installed above RPM)

- User & group create (Not required)

# groupadd dba

# groupadd oinstall

# useradd -g oinstall -G oinstall,dba oracle

Advantages of oracle pre-requisite rpm installation

- all kernel parameter are set

- all the required rpms are auto installed

- all the oracle user and groups are auto created

- Change permission

#chown -R oracle:oinstall /u01

- passwd oracle (set password)

- Database SW Installation / Oracle SW Installation / Oracle Home Installation (from GUI screen as oracle user)

$ cd /u01/app/oracle/product/26ai/dbhome_1

$ ./runInstaller

2. Create Database -> ORA26AI

$ cd /u01/app/oracle/product/26ai/dbhome_1/bin (from GUI screen as oracle user)

$ ./dbca
