132. #  Backs up the whole database.  This backup is part of the incremental

133. #  strategy (this means it can have incremental backups of levels > 0

134. #  applied to it).

135. #

136. #  We do not need to explicitly request the control file to be included

137. #  in this backup, as it is automatically included each time file 1 of

138. #  the system tablespace is backed up (the inference: as it is a whole

139. #  database backup, file 1 of the system tablespace will be backed up,

140. #  hence the controlfile will also be included automatically).

141. #

142. #  Typically, a level 0 backup would be done at least once a week.

143. #

144. #  The scenario assumes:

145. #     o you are backing your database up to two tape drives

146. #     o you want each backup setto include a maximum of 5 files

147. #     o you wish to include offline datafiles, andread-only tablespaces,

148. #       in the backup

149. #     o you want the backup tocontinue if any files are inaccessible.

150. #     o you are not using a Recovery Catalog

151. #     o you are explicitly backing up the control file.  Since you are

152. #       specifying nocatalog, the controlfile backup that occurs

153. #       automatically as the result of backing up the system file is

154. #       not sufficient; it will not contain records for the backup that

155. #       is currently in progress.

156. #     o you want to archive the current log, back up all the

157. #       archive logs using two channels, putting a maximum of 20 logs

158. #       in a backup set, and deleting them once the backup is complete.

159. #

160. #  Note that the format string is constructed to guarantee uniqueness and

161. #  to enhance NetBackup for Oracle backup and restore performance.

162. #

163. #

164. #  NOTE WHEN USING NET SERVICE NAME: When connecting to a database

165. #  using a net service name, you must use a send command or a parms operand to

166. #  specify environment variables.  In other words, when accessing a database

167. #  through a listener, the environment variables setat the system level are not

168. #  visible when RMAN is running.  For more information on the environment

169. #  variables, please refer to the NetBackup for Oracle Admin. Guide.

每天早上的3點進行備份，另外我們還需要的就是在RMAN中配置備份的保留時間與controlfile與spfile的自己備份。
