Download Software


Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.

<IP-address> <fully-qualified-machine-name> <machine-name>

Oracle Installation Prerequisites

Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites.

Manual Setup

If you have not used the "oracle-database-preinstall-19c" package to perform all prerequisites, 

Add the following lines to the "/etc/sysctl.conf" file,

# Customised parameters
vm.pagecache=1 15 30
vm.min_free_kbytes=1024
vm.swappiness=10
#kernel.shmmax = 68719476736
#kernel.shmall = 4294967296
kernel.shmmni=4096
kernel.sem = 1820 232960 1820 128
net.core.rmem_default = 262144
net.core.wmem_default = 262144
fs.aio-max-nr = 3145728
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576

Run one of the following commands to change the current kernel parameters

/sbin/sysctl -p
# Or
/sbin/sysctl -p /etc/sysctl.d/98-oracle.conf

Add the following lines to a file called "/etc/security/limits.d/oracle-database-preinstall-19c.conf" file.

* hard nofile 65535
* soft nofile 4096
* hard nproc 16386
* soft nproc 2047

The following packages are listed as required. Many of the packages should be installed already.

Set the password for the "oracle" user.

passwd oracle
Set secure Linux to permissive by editing the "/etc/selinux/config" file, ensuring the SELINUX flag is set as follows.
SELINUX=permissive
Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1
mkdir -p /u02/oradata
chown -R oracle:oinstall /u01 /u02
chmod -R 775 /u01 /u02
unless you are working from the console, or using SSH tunnelling, login as root and issue the following command.
xhost +<machine-name>

Create a "scripts" directory.

mkdir /home/oracle/scripts
cat > /home/oracle/scripts/setEnv.sh <<EOF
# Oracle Settings
export TMP=/tmp
export TMPDIR=\$TMP

export ORACLE_HOSTNAME=ol7-19.localdomain

export ORACLE_HOME=\$ORACLE_BASE/product/19.0.0/dbhome_1
export ORA_INVENTORY=/u01/app/oraInventory
export ORACLE_SID=cdb1
export PDB_NAME=pdb1
export DATA_DIR=/u02/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
EOF

Add a reference to the "setEnv.sh" file at the end of the "/home/oracle/.bash_profile" file.

echo ". /home/oracle/scripts/setEnv.sh" >> /home/oracle/.bash_profile


Create a "start_all.sh" and "stop_all.sh" script that can be called from a startup/shutdown service. Make sure the ownership and permissions are correct.

cat > /home/oracle/scripts/start_all.sh <<EOF
#!/bin/bash
. /home/oracle/scripts/setEnv.sh

export ORAENV_ASK=NO
. oraenv
export ORAENV_ASK=YES

dbstart \$ORACLE_HOME
EOF


cat > /home/oracle/scripts/stop_all.sh <<EOF
#!/bin/bash

export ORAENV_ASK=NO
. oraenv
export ORAENV_ASK=YES

dbshut \$ORACLE_HOME
EOF

chown -R oracle:oinstall /home/oracle/scripts
chmod u+x /home/oracle/scripts/*.sh

Once the installation is complete and you've edited the "/etc/oratab", you should be able to start/stop the database with the following scripts run from the "oracle" user.

~/scripts/start_all.sh
~/scripts/stop_all.sh

Installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.

DISPLAY=<machine-name>:0.0; export DISPLAY

un the root scripts when prompted.

As a root user, execute the following script(s):
        1. /u01/app/oraInventory/orainstRoot.sh
        2. /u01/app/oracle/product/19.0.0/dbhome_1/root.sh

Database Creation

You create a database using the Database Configuration Assistant (DBCA). The interactive mode will display GUI screens to allow user input, while the silent mode will create the database without displaying any screens, as all required options are already specified on the command line.

# Start the listener.
lsnrctl start

# Interactive mode.
dbca

# Silent mode.
dbca -silent -createDatabase                                                   \

Post Installation

Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.

cdb1:/u01/app/oracle/product/19.0.0/dbhome_1:Y

Enable Oracle Managed Files (OMF) and make sure the PDB starts when the instance starts.

sqlplus / as sysdba <<EOF
alter system set db_create_file_dest='${DATA_DIR}';
alter pluggable database ${PDB_NAME} save state;
exit;
EOF

Configure Oracle Database Vault Realms

-
Configure Oracle Database Vault Realms to Secure the HR Schema Oracle Database Vault (DV) is a powerful security feature that enables fine-grained access control by enforcing security policies that protect sensitive data. One of the most important components in Database Vault is the Realm , which creates a security boundary around database objects to prevent unauthorized access — even by highly privileged users. In this blog, we’ll walk through the step-by-step process of configuring a Realm to secure the HR schema in an Oracle Database 19c environment. You’ll learn how to: Create a Realm Add objects to it Restrict access Enable auditing for security tracking What is a Realm? A Realm in Oracle Database Vault defines a logical security boundary around one or more database objects. Once a Realm is in place, no one — not even privileged users like DBAs — can access the protected objects without being explicitly authorized. Realms are ideal for: Securing sensitive ap...

   Configure Transparent Database Encryption (TDE) in Oracle CDB Transparent Data Encryption (TDE) is a vital Oracle feature used to secure sensitive data at rest by encrypting database files. In this guide, we'll walk through configuring TDE in a CDB (Container Database) environment and demonstrate its effectiveness with a test tablespace and HR schema. Prerequisites Oracle Database (12c and above, preferably 19c or later) File system access to create wallets Appropriate privileges to administer TDE and manage tablespaces Step 1: Create a New Tablespace in PDB Connect to the PDB and create a new tablespace: sql SQL > CREATE TABLE SPACE userstab DATAFILE '/opt/oracle/oradata/XE/XEPDB1/userstab01.dbf' SIZE 1 G; Tablespace created.
