Oracle Database 19c Installation on OEL 8.10

Operating System Setup

1. For Automatic Setup of Operating System Packages and Parameters, Run the following command with Root user [root@oidserver ~]# dnf install -y oracle-database-preinstall-19c

If you are using RHEL8 or CentOS8, you can pick up the RPM from the OL8 repository and install it. It will pull the dependencies from your normal repositories. curl -o oracle-database-preinstall-19c-1.0-2.el8.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL8/appstream/x86_64/getPackage/oracle-database-preinstall-19c-1.0-2.el8.x86_64.rpm dnf -y localinstall oracle-database-preinstall-19c-1.0-2.el8.x86_64.rpm

2. Set the password for the “oracle” user. [root@oamserver ~]# passwd oracle 3. Set secure Linux to permissive by editing the “/etc/selinux/config” file, making sure the SELINUX flag is set as follows. SELINUX=permissive 4. Once the change is complete, restart the server or run the following command. [root@oamserver ~]# setenforce Permissive 5. Once the change is complete, restart the server or run the following command. If you have the Linux firewall enabled, you will need to disable or configure it. To disable it, do the following. # systemctl stop firewalld
# systemctl disable firewalld 6. Create the directories in which the Oracle software will be installed. [root@oamserver ~]# mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1 [root@oamserver ~]# chown -R oracle:oinstall /u01/app [root@oamserver ~]# chmod -R 775 /u01 7. Create an Environment Variable file for the Oracle Database on the Oracle User Home Directory

[oracle@oamserver ~]$ vi setEnv.sh # Oracle Settings export TMP=/tmp export TMPDIR=$TMP export ORACLE_HOSTNAME=oidserver.com export ORACLE_UNQNAME=OAMDB export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/19.0.0/dbhome_1 export ORA_INVENTORY=/u01/app/oraInventory export ORACLE_SID=OAMDB export DATA_DIR=/u01/oradata export PATH=/usr/sbin:/usr/local/bin:$PATH export PATH=$ORACLE_HOME/bin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib [oracle@oidserver ~]$

8. Unzip Software Binaries Copy the Downloaded Database 19c Zip (V982063-01.zip) file on the /u01/app/oracle/product/19.0.0/dbhome_1 Directory [oracle@oamserver ~]$ cd /u01/app/oracle/product/19.0.0/dbhome_1 [oracle@oamserver dbhome_1]$ unzip -oq V982063-01.zip
