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' *.control_files='/opt/app/oracle/can/redo1/control.ctl','/opt/app/oracle/can/redo2/control.ctl' *.db_block_size=8192 *.db_domain='yaocm.id.au' *.db_name='can' *.db_recovery_file_dest='/opt/app/oracle/can/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/can/oradata mkdir -p /opt/app/oracle/can/redo1 mkdir -p /opt/app/oracle/can/redo2 mkdir -p /opt/app/oracle/can/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 (           '/opt/app/oracle/can/redo1/redo01.log',           '/opt/app/oracle/can/redo2/redo01.log')           size 50m,         group 2 (           '/opt/app/oracle/can/redo1/redo02.log',           '/opt/app/oracle/can/redo2/redo02.log')           size 50m,         group 3 (           '/opt/app/oracle/can/redo1/redo03.log',           '/opt/app/oracle/can/redo2/redo03.log')           size 50m character set al32utf8 national character set al16utf16 extent management local   datafile '/opt/app/oracle/can/oradata/system01.dbf'   size 200m reuse autoextend on next 5m maxsize unlimited sysaux   datafile '/opt/app/oracle/can/oradata/sysaux01.dbf'   size 200m reuse autoextend on next 5m maxsize unlimited default temporary tablespace temp   tempfile '/opt/app/oracle/can/oradata/temp01.dbf'   size 200m reuse autoextend on next 5m maxsize unlimited default tablespace users   datafile '/opt/app/oracle/can/oradata/users01.dbf'   size 200m reuse autoextend on next 5m maxsize unlimited undo tablespace undotbs1   datafile '/opt/app/oracle/can/oradata/undotbs101.dbf'   size 200m reuse autoextend on next 5m maxsize unlimited /

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
