The default database configuration file uses the following parameters:
[root@odanode1 ~]# oakcli show db_config_params
The available DB configuration files are :
default
[root@odanode1 ~]# oakcli show db_config_params -conf default -detail
DATABASE_BLOCK_SIZE => 8192
DATABASE_LANGUAGE => AMERICAN
DATABASE_CHARACTERSET => AL32UTF8
DATABASE_TERRITORY => AMERICA
COMPONENT_LANGUAGES => en
NLS_NCHAR_CHARACTERSET => AL16UTF16
If you want to create a database with different database configuration parameter then you must create a database configuration file with your desired parameters. You can use the ‘oakcli create db_config_params’ command to create a database configuration file. The configuration files are created under the locatoin ‘/opt/oracle/oak/install/dbconf’ with a default extension of ‘.dbconf’.
In this article we will demonstrate how to create a database configuration file.
Steps to generate/create a database configuration file
Step 1: List the Database Configuration files
[root@odanode1 ~]# oakcli show db_config_params
The available DB configuration files are :
default
Step 2: Create Database Configuration file
[root@odanode1 dumpfiles]# oakcli create db_config_params -conf newdbconf
