[26ai] Install Oracle AI Database 26ai on Linux 9

If you prefer to read in Spanish Spanish version.

Today, we're going to see how to set up Oracle 26ai on Linux 9.

[root@~]# grep PRETTY /etc/os-release
PRETTY_NAME="Oracle Linux Server 9.7"

First of all, we need to download an Oracle 26ai pre-installation from here.

After downloading the rpm, let's set it up.

root@~]# ls -lac oracle-ai-database-preinstall-26ai-1.0-1.el9.x86_64.rpm
-rw-r--r--. 1 root root 35302 mar  8 11:39 oracle-ai-database-preinstall-26ai-1.0-1.el9.x86_64.rpm
[root@~]# dnf -y install oracle-ai-database-preinstall-26ai-1.0-1.el9.x86_64.rpm
   
...
...
¡Listo!

Done!, Let's check whether the oracle user exists on our machine in order to create ORACLE_HOME directory.

[root@~]# id oracle
uid=54321(oracle) gid=54321(oinstall) grupos=54321(oinstall),54322(dba),54323(oper),54324(backupdba),54325(dgdba),54326(kmdba),54330(racdba)
[root@~]# 
[root@~]# mkdir -p /u01/app/oracle/product/23.26.1/dbhome_1
[root@~]# chown -R oracle:oinstall /u01 && chown -R oracle:oinstall /u01
[root@~]# su - oracle
[oracle@~]$ cd /u01/app/oracle/product/23.26.1/dbhome_1/

Let's edit the .bashrc and bash_profile files in order to set up the following variables:

[oracle@~]$ tail -8 .bashrc
# User specific aliases and functions
ORACLE_BASE=/u01/app/oracle/
ORACLE_HOME=/u01/app/oracle/product/23.26.1/dbhome_1; export ORACLE_HOME
PATH=\(PATH:\){ORACLE_HOME}/bin; export PATH
LD_LIBRARY_PATH={ORACLE_HOME}/lib; export LD_LIBRARY_PATH

Lastly, let's download Oracle AI Database 26ai (23.26.1) for Linux x86-64 from here.

After downloading it, let's copy the file to the following path:

• /u01/app/oracle/product/23.26.1/dbhome_1.

[oracle@]$ pwd && ls -lash
/u01/app/oracle/product/23.26.1/dbhome_1
total 2,3G
   0 drwxr-xr-x. 2 oracle oinstall   43 mar 14 12:12 .
   0 drwxr-xr-x. 3 oracle oinstall   22 mar  9 22:54 ..
2,3G -rwxr-x---. 1 oracle oinstall 2,3G mar 14 12:18 LINUX.X64_2326100_db_home.zip
[oracle@]$ unzip LINUX.X64_2326100_db_home.zip

Let's modify the response file because we'll use silent mode in order to set it up.

[oracle@]$ vi install/response/db_install.rsp
[oracle@]\( grep -v "#" install/response/db_install.rsp | grep -v '^\)'
oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v23.0.0
installOption=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=${ORA_INVENTORY}
ORACLE_HOME=/u01/app/oracle/product/23.26.1/dbhome_1
ORACLE_BASE=/u01/app/oracle/
installEdition=EE
OSDBA=dba
OSBACKUPDBA=dba
OSDGDBA=dba
OSKMDBA=dba
OSRACDBA=dba
[oracle@]$ ./runInstaller -silent -responsefile install/response/db_install.rsp

Let's run the folowing scripts as the root user:

[root@~]# .  /u01/app/oraInventory/orainstRoot.sh
...
[root@~]# .  /u01/app/oracle/product/23.26.1/dbhome_1/root.sh
...

Let's verify our instalation.

[oracle@~]$ sqlplus /nolog
