Introduction

In my previous articles, we have learned how to Deploy an Oracle Database Appliance. 
One can use OAKCLI or DBCA utility to create the database on ODA. But it is recommended to use OAKCLI on ODA to create the database.
With OAKCLI, creating database is very easy and it is just one command.
Let’s see how to quickly create a database on ODA.

Steps to create Database on ODA

• List the existing RDBMS Oracle Homes. With OAKCLI it is very easy to get the Oracle Homes Printed.

[root@odanode1 ~]# oakcli show dbhomes
Oracle Home Name Oracle Home version Home Location
—————- ——————- ————
OraDb12102_home1 /u01/app/oracle/product/12.1.0.2/dbhome_1

You can also use the following option to get the Oracle HOME Name.

[root@odanode1 ~]# cd /u01/app/oraInventory/ContentsXML
[root@odanode1 ContentsXML]# grep -i “HOME NAME” inventory.xml
<HOME NAME=”OraGrid12102″ LOC=”/u01/app/12.1.0.2/grid” TYPE=”O” IDX=”1″ CRS=”true”>
<HOME NAME=”OraDb12102_home1″ LOC=”/u01/app/oracle/product/12.1.0.2/dbhome_1″ TYPE=”O” IDX=”2″>

Here we have only Oracle HOME name OraDb12102_home1. We will be using this name to create the database.

• Using OAKCLI to create database. Let’s see the options available.

Display options that can be used with OAKCLI

[root@odanode1 ~]# oakcli -h
Usage:  oakcli show       – Shows disk, diskgroup, expander, controller, server, processor, memory, power, cooling, network, enclosure, storage, version, fs, raidsyncstatus, dbhomes, 

dbstorage, databases, db_config_params, core_config_key, env_hw, ASR
        oakcli configure  – Configures the Network or ASR or additional Net
        oakcli apply      – Applies the core_config_key
        oakcli locate     – Locates a disk
        oakcli deploy     – Deploys the Database Appliance
        oakcli update     – Updates the Database Appliance
        oakcli validate   – Validates the Database Appliance
        oakcli manage     – Manages the OAK repository, diagcollect etc.,
        oakcli unpack     – Unpack the given package to OAK repository
        oakcli copy       – Copies the deployment config file
        oakcli upgrade    – Upgrades database
        oakcli stordiag   – Run storage diagnostic tool on both Nodes
        oakcli test       – Test ASR
        oakcli orachk     – Performs configuration settings check on ODA
        oakcli create     – Creates Database, DB storage, snapshotdb, dbhome, db_config_params file
        oakcli delete     – Deletes Database, DB storage, dbhome, db_config_params file
        oakcli modify     – Performs modify opeartions on Database
        oakcli resize     – Resizes DB storage

Display options that can be used with OAKCLI CREATE

[root@odanode1 ~]# oakcli create -h
Usage:
oakcli create {database | dbstorage | snapshotdb| dbhome | db_config_params } [<options>]
Where:
         database            – Creates the Database
         snapshotdb          – Creates the Snapshot Database
         dbhome              – Creates the Database Home
         dbstorage           – Creates Storage for a given Database
         db_config_params    – Creates the Database configuration parameter file

Display options that can be used with OAKCLI CREATE DATABASE 

[root@odanode1 ~]# oakcli create database -h
Usage:
      oakcli create database  -db <db_name> [[[-oh <home>] | [-version <version>]]  [-params <params_file>] [-cdb]]

      where:
         db_name      – Name of the database to be created.
         home         – Existing oracle home for creating the database. By default we create a new database home.
         version      – Database Version information for creating the database home. [ex. 11.2.0.2.7] If not provided create the database home from latest available bits.
         params_file  – Name of the db_config_parameter file [This file can be created using using ‘oakcli create db_config_params’].
                        If not provided, create the database using  default configuration file
         cdb          – Creates this database as a container database

• Create Database as follows

When you execute the create database command, it will prompt you the following details:

• root password
• SYSASM password
• Databsae Type (OLTP, DSS or In-Memory)
• Database Deployment (EE, RACONE or RAC)
• Database Class

[root@odanode1 ~]# oakcli create database -db odatest -oh OraDb12102_home1
