Create 12C Non-CDB Database Using OMF


Overview

This is a sample procedure a non-CDB Oracle 12.1.0.2 database with OMF.

Procedure

Preliminaries

The procedure to follow can be found in Creating a Database with the CREATE DATABASE Statement .

Step 1: Specify an Instance Identifier (SID)

The database and instance name is CAN .

Step 2: Ensure That the Required Environment Variables Are Set

The following update is made to /etc/oratab :

can:/opt/app/oracle/product/12.1.0/dbhome_1:N

The appropriate environment variables are set as follows:

. oraenv

Step 3: Choose a Database Administrator Authentication Method

The password file is created as follows:

cd ${ORACLE_HOME}/dbs
orapwd file=orapwd${ORACLE_SID}

Step 4: Create the Initialization Parameter File

The following data is entered into /home/oracle/initcan.ora :

*.audit_file_dest='/opt/app/oracle/admin/can/adump'
*.audit_trail='db'
*.compatible='12.1.0.2.0'

*.db_block_size=8192
*.db_create_file_dest='/opt/app/oracle/oradata'
*.db_create_online_log_dest_1='/opt/app/oracle/oradata'
*.db_create_online_log_dest_2='/opt/app/oracle/fast_recovery_area'
*.db_domain='yaocm.id.au'
*.db_name='can'
* .db_recovery_file_dest='/opt/app/oracle/fast_recovery_area'
*.db_recovery_file_dest_size=4560m
*.diagnostic_dest='/opt/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=canXDB)'
*.memory_target=1470m
*.open_cursors=300
*.processes=300
*.remote_login_passwordfile='EXCLUSIVE'
*.undo_tablespace='UNDOTBS1'

The following directories are created:

mkdir -p /opt/app/oracle/admin/can/adump
mkdir -p /opt/app/oracle/oradata
mkdir -p /opt/app/oracle/fast_recovery_area

Step 6: Connect to the Instance

Instead of following the procedure, I used the following commands instead:

sqlplus / as sysdba
startup nomount pfile=/home/oracle/initcan.ora

The reason is to check the syntax and validity of the initialization parameters before creating the spfile.

Step 7: Create a Server Parameter File

The spfile is created in the default location ( ${ORACLE_HOME}/dbs ) as follows:

CREATE SPFILE FROM PFILE='/home/oracle/initcan.ora';

Step 8: Start the Instance

The instance is started using the spfile:

startup nomount force

Step 9: Issue the CREATE DATABASE Statement

The database is created using the following command:

create database can
user sys identified by "&pw_sys"
user system identified by "&pw_system"
logfile group 1 size 50m,
group 2 size 50m,
group 3 size 50m
character set al32utf8 national character set al16utf16
set default bigfile tablespace
archivelog
set time_zone='+10:00'
extent management local
default temporary tablespace temp
undo tablespace undotbs1
/
create tablespace users;
alter database default tablespace users;

The default tablespace, USERS, is created separately because I have found the CREATE DATABASE command to fail when using BIGFILE as the default.

Step 11: Run Scripts to Build Data Dictionary Views

The following commands are run:

@?/rdbms/admin/catalog.sql
@?/rdbms/admin/catproc.sql
connect system/&pw_system
@?/sqlplus/admin/pupbld.sql
