Configuring Users, Groups and Environments for Oracle Grid Infrastructure and Oracle Database

Create Oracle software owner user accounts.

groupadd -g 54321 oinstall
groupadd -g 54322 dba
groupadd -g 54323 oper
useradd -u 54321 -g oinstall -G dba,oper -m -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle
echo "oracle" | passwd --stdin oracle

Create Oracle software directories.

mkdir -p /u01/app/oracle/product/11.2.0.4/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01

Configure Oracle software owner user account environment.

cat >> /home/oracle/.bash_profile <<"EOF"
# Oracle 11g
export ORACLE_SID=coco
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/db_1
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
if command -v rlwrap >/dev/null 2>&1; then
  alias sqlplus='rlwrap sqlplus'
