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 :

The appropriate environment variables are set as follows:

Step 3: Choose a Database Administrator Authentication Method

The password file is created as follows:

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:

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:

Step 8: Start the Instance

The instance is started using the spfile:

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

  size 200m reuse autoextend on next 5m maxsize unlimited

  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

  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
