How to create database through Graphical tool "DBCA" Database Configuration Assistant

Step 1) You need to go to the ORACLE_HOME/bin location manually to run the DBCA utility

Click on below "Next" button to proceed further

Step 3) Click on "Create a Database" tab to proceed further

Step 4) Click on "General Purpose or Transaction Processing" tab because we are using for practice purpose but in real environment  choose options as per the requirement

Step 5) Put the name of Database which you need to create, in my case it is "orcl"

Step 6) Check the "Configure Enterprise Manager" tab and "Automatic Maintenance Tasks" tab, but make sure your listener is up and running, otherwise, you need to uncheck "Configure Enterprise Manager" tab to proceed further

Step 7) Put all the password for below-listed accounts, you have options to put passwords of all the account separately or also have options to put the same password for all the accounts

Step 8) Under storage options you can choose "File System" because we are using a file system to build the database, not ASM (Automatic Storage Management)

Step 9) Check the "Fast Recovery Area" tab if you want to put your backups in a single location

Step 10) If you want to create some schema's by default like HR, Online Catalog etc then you can check the "Sample Schema" option

Step 11) Choose memory options as "Typical" to give SGA and PGA together through AMM (Automatic Memory Management) and choose the default value for rest of the options

Step 12) Click on "Finish" tab to create a database
