Hello, experts
Today I try to install Oracle Database 18.3 using RPM-based package on my Oracle Linux Server 7.5 (Test Environment). It's all normal after I deploy it.
Nevertheless I add some contents on environment configuration file ".bash_profile" on oracle user. Such as follows,
[oracle@ncet ~]$ cat .bash_profile
......
export ORACLE_BASE=/opt/oracle/
export ORACLE_HOME=$ORACLE_BASE/product/18c/dbhome_1
export ORACLE_SID=ORCLCDB
export PATH=$ORACLE_HOME/bin:$PATH
alias t='cd /opt/oracle/diag/rdbms/orclcdb/ORCLCDB/trace'
alias l='cd /opt/oracle/diag/tnslsnr/ncet/listener/trace'
Afterwards I login to SQL*Plus and it has shown "idle instance".
[oracle@ncet ~]$
[oracle@ncet ~]$ source .bash_profile
[oracle@ncet ~]$
[oracle@ncet ~]$ sqlplus / as sysdba
SQL*Plus: Release 18.0.0.0.0 - Production on Tue Oct 30 12:30:39 2018
Version 18.3.0.0.0

Connected to an idle instance.
SQL>
[oracle@ncet ~]$ echo $ORACLE_SID
ORCLCDB
It's why? Could you help me? Thanks in advance.
