Step-1: Set the bash profile parameters as follows. Bash profile file should consist the following Oracle Home and SID parameters.


bash-4.3$ cat .bash_profile


export PATH

if [ -s "$MAIL" ] # This is at Shell startup. In normal
then echo "$MAILMSG" # operation, the Shell checks
fi # periodically.

export ORACLE_HOME=/u01/app/oracle/product/19c



Step-2: Create a Parameter file ( PFILE ) for Oracle Instance as follows.


bash-4.3$ cat initDEPLOY.ora
control_files = '+DATATEST/DEPLOY/controlfile/controlfile01.ora'
undo_management = AUTO
undo_tablespace = UNDOTBS1
db_name = DEPLOY
db_block_size = 16384
sga_max_size = 20073741824
sga_target = 20073741824


Step-3: Set .bash_Profile and Startup Oracle instance in Nomount mode using PFILE as follows.


bash-4.3$ . .bash_profile

bash-4.3$ sqlplus / as sysdba

SQL> startup nomount pfile=initDEPLOY.ora
ORACLE instance started.

Total System Global Area 2.1379E+10 bytes
Fixed Size 2237776 bytes
Variable Size 8522828464 bytes
Database Buffers 1.2818E+10 bytes
Redo Buffers 36098048 bytes




Step-4: Create a Password file for Admin users.

$ORACLE_HOME/bin/orapwd file=$ORACLE_HOME/dbs/orapwDEPLOY.ora password=welcome1 entries=5


Step-5: Execute Create Database statement as follows to create an Oracle Database.

SQL> create database DEPLOY
logfile group 1 ('+DATADEPLOY/DEPLOY/onlinelog/redo01.log') size 100M,
group 2 ('+DATADEPLOY/DEPLOY/onlinelog/redo02.log') size 100M,
group 3 ('+DATADEPLOY/DEPLOY/onlinelog/redo03.log') size 100M
character set AL32UTF8
national character set AL16UTF16
datafile '+DATADEPLOY/DEPLOY/datafile/system01.dbf' size 500M autoextend on next 10M maxsize unlimited extent management local
sysaux datafile '+DATADEPLOY/DEPLOY/datafile/sysaux01.dbf' size 100M autoextend on next 10M maxsize unlimited
undo tablespace undotbs1 datafile '+DATADEPLOY/DEPLOY/datafile/undotbs01.dbf' size 100M
default temporary tablespace temp tempfile '+DATADEPLOY/DEPLOY/datafile/temp01.dbf' size 100M;



Step-6: If Step-5 is completed successfully, then execute the following SQLs to create system based objects.

SQL> @?/rdbms/admin/catalog.sql

SQL> @?/rdbms/admin/catproc.sql


If the Step-6 SQLs are executed successfully, then your database is ready to use.



Or you can create an Oracle database using DBCA ( Database configuration Assistant ) tool, You can use DBCA tool in silent mode as follows.

bash-4.3$ dbca -createDatabase -silent \
-gdbName DEPLOY \
-sid DEPLOY \
-sysPassword welcome1 \
-systemPassword welcome1 \
-diskGroupName 'DATATEST' \
-recoveryGroupName 'DATATEST' \
-storageType ASM \
-asmSysPassword welcome1 \
-nodelist 'MehmetSalih' \
-databaseType MULTIPURPOSE \
-responseFile NO_VALUE \
-asmsnmpPassword welcome1 \
-characterSet AL32UTF8 \
-nationalCharacterSet AL16UTF16 \
-memoryPercentage 3 \
-initparams audit_trail=NONE,db_recovery_file_dest_size=3000,db_block_size=8192 \
-templateName /u01/app/oracle/product/19c/assistants/dbca/templates/General_Purpose.dbc
