Initializing Databases 
When you initialize a database, you delete all data (including the application data and database catalog) and all log entries from the volumes. The configuration of the database (database parameters, volume definitions, and so on) is retained, however.
Initializing a database is required in special recovery situations, for example.
Prerequisites
You are logged on to the database as database system administrator or as a DBM operator with server authorization for accessing utility sessions.

For a database on the local computer, you require administration authorizations for the computer as an operating system user.
For a database on a remote computer, you must be logged on to the remote computer as an operating system user with the following authorizations: administration authorizations and on Microsoft Windows additionally the Log on as batch job authorization. For more information, see your operating system documentation.
The database is in the OFFLINE operational state.
