How do you create a database in Linux Oracle?

The method to create a database using Oracle database software is either through the SQL*Plus command line tool or the Oracle Enterprise Manager graphical user interface tool.

1. Create a database using the SQL*Plus command line tool.
2. Open the terminal or command prompt, type sqlplus /nolog to enter the SQL*Plus command-line tool.
3. Enter conn / as sysdba to connect to the database.
4. To create a database, use the following command:
   CREATE DATABASE database_name
   USER sys IDENTIFIED BY password
   USER system IDENTIFIED BY password
   LOGFILE ‘path_to_redo_log_file’ SIZE size
   MAXLOGFILES number
   MAXLOGMEMBERS number
   MAXDATAFILES number
   MAXINSTANCES number
   CHARACTER SET character_set;

   Here, database_name is the name of the database, password is the password for the sys and system users, path_to_redo_log_file is the path to the redo log file, size is the size of the redo log file, number refers to the maximum number of log files, log members, data files, and instances, and character_set is the character set for the database.

5. Type EXIT to exit the SQL*Plus command line tool.
6. Create a database with Oracle Enterprise Manager’s graphical user interface tool.
7. Open the graphical interface tool for Oracle Enterprise Manager.
8. Navigate to the “Database” section and select the “Create Database” option.
9. Follow the instructions in the database creation wizard to set up the database, including database name, storage location, character set, and administrator user.
10. After completing the settings, click the “create” button to create the database.

Regardless of the method used to create a database, it is important to properly configure the parameters and options to meet the requirements of the application.
