Creating and updating duplicate databases with rman Free online sex chat nocredit card need
When active database duplication is performed using image copies, after RMAN establishes a connection with the source database, the source database transfers the required database files to the auxiliary database.Using image copies may require additional resources on the source database.RMAN must perform database point-in-time recovery, even when no explicit point in time is provided for duplication.Point-in-time recovery is required because the online redo log files in the source database are not backed up and cannot be applied to the duplicate database.
The destination host must have access to the RMAN backups required to create the duplicate database.A database copy, however, cannot be used in this way: it is not intended for failover scenarios and does is the computer that hosts the duplicate database.The source host and destination host can be the same or different computers.The destination host must have access to the RMAN backups required to create the duplicate database. These channels correspond to a server session on the auxiliary instance on the destination host.For active database duplication, the type of duplication technique used determines which channel performs the principal work.
of the copied database remains the same as the original database.
