Explanation:

DB_NAME and INSTANCE_NAME specify the database name and instance name, respectively.
DB_BLOCK_SIZE specifies the database block size.
LOG_FILE_SIZE and REDO_LOG_SIZE specify the size of the log files and redo logs, respectively.
ARCHIVE_LOG_DESTINATION specifies the location where archive logs will be written.
CONTROL_FILES specifies the location of the control files.
BACKUP_CONTROL_FILE specifies the location of the backup control file.
ORACLE_HOME specifies the location of the Oracle home directory.
SAP_INSTANCE, SAP_SYSNR, SAP_CLIENT, SAP_SYSID, and SAP_DBNAME specify SAP-related parameters.

Note:

Make sure to replace the file paths and values with the actual values for your Oracle 12c and SAP environment.
The control file should be created in the ORACLE_HOME/dbs directory.
The control file should be named oraparam.ctl (or any other name specified in the CONTROL_FILES parameter).
The control file should be edited using a text editor, such as vi or emacs, and not using a word processor like Microsoft Word.

After creating the control file, you can start the Oracle instance using the following command:

sqlplus / as sysdba
startup

This will start the Oracle instance and create the database specified in the control file.
