Creating an Oracle 11g Database using DBCA (non-ASM)

In this example, I’ve already installed the Oracle Database 11gR2 software (11.2.0.4 in this example) on one of my Linux 6.4 machines, and I’m going to create a new database instance simply called ‘emrep’ (as it’s going to be used for my EM12c database repository) using the DBCA tool.

The data files will be stored under the /u02/oradata/{DB_NAME} directory, setup by ‘root’ as follows:

mkdir -p /u02/oradata/emrep
chown -R oracle:oinstall /u02
chmod -R 775 /u02

Start the Database Configuration Assistant (DBCA)

Open an X-Windows session to the server as the ‘oracle’ user.

Set your ORACLE_HOME environment variable appropriately, then start the assistant by running the following:

export ORACLE_HOME=/u01/app/oracle/product/11.2.0.4
$ORACLE_HOME/bin/dbca

Once the GUI starts, respond as follows:

  • Welcome
    • Next
  • Step 1 of 12: Operations
    • Create a Database
    • Next

  • Step 2 of 12: Database Templates
    • General Purpose or Transaction Processing
    • Next

  • Step 3 of 12: Database Identification
    • Global Database Name: emrep (or any name you want providing it’s no more than 8 characters long, and starts with an alphabetic character)
    • SID: emrep
    • Next

  • Step 4 of 12: Management Options
    • Tick/Untick ‘Configure Enterprise Manager’ according to your needs.

If you do want to configure Enterprise Manager locally, and a listener hasn’t yet been configured, you’ll be presented with a warning about having to configure one before being able to continue.  If you need to create a listener service, take a look at this post.

    • Leave everything else as default
    • Next

  • Step 5 of 12: Database Credentials
    • Use the Same Administrative Password for All Account (unless you’d rather not)
    • Password: ******
    • Confirm Password: ******
    • Next

  • Step 6 of 12: Management Options
    • Specify storage type and locations for database files
    • Storage Type: File System
    • Use Common Location for All Database Files
    • Database Files Location: /u02/oradata
    • Next

  • Step 7 of 12: Recovery Configuration
    • Tick Specify Fast Recovery Area
    • Fast Recovery Area: {ORACLE_BASE}/fra
    • Tick Enable Archiving
    • Click on Edit Archive Mode Parameters…
      • Archive Log File Format: %t_%s_%r.arc
      • OK
    • Next

 

  • Step 8 of 12: Database Content
    • Optionally, check ‘Sample Schemas’ (this will create an ‘EXAMPLE’ tablespace and some sample schemas).  I recommend leaving this unticked if this is to become a live environment.
    • Next

  • Step 9 of 11: Initialization Parameters
    • Use a Typical configuration
    • Tick ‘Use Automatic Memory Management’
    • Change the ‘Memory Size’ value accordingly (or leave default as 40% of total machine memory)
    • Review any additional parameters by clicking ‘All Initialization Parameters’
    • Next

   

  • Step 10 of 11: Database Storage
    • Check storage locations/options and update accordingly if required
    • Next

    

  • Step 11 of 11: Creation Options
    • Optionally tick ‘Generate Database Creation Scripts’ if you prefer to keep it for future reference.
    • Finish
  • Confirmation
    • Check the ‘Create Database – Summary’ details
    • OK

   

    • Once the database has been created, note the message about all accounts being locked with the exception of SYS and SYSTEM.
