Use this way: different machine recovery, similar to the hand-built library : The difference is that, before the data is there, instead of using a backup script before the backup file is the use of control
Heterogeneous recovery scenarios: A: G dozens of test library, you need to complete the test data replication, migration to another database, using RMAN and Data Pump / exp, has obvious advantages, the use of this scene quickly erected
B: disaster recovery Walkthrough: backup, restore, by way of different machines, verify the availability of backup
Backup distinguished : A full backup archive log transfer transmission + + + Control parameter file + password file password file
B All libraries 0 backup + incremental backup ----
The experimental tests: A / B A- 0 all equipment used: a manner similar to the full backup, restore different machines
BA experiment is successful , delete the backup of all data and information, and start again, using a full backup +1 level incremental backup test
Heterogeneous recovery process:
Source:
Experimental environment: 10.2.0.4
Full backup: parameter files - Control files - data files - archive log files
Transmission : backup information from the source - to copy - the destination end
End goal:
Creating preparation: create the appropriate directory: password file: change the name of the parameter file
Modify the parameter file:
Parameter file is used to start Nomount state
RMAN: control files backup, restore restored to the parameters specified by the control file file name, path
RMAN: Register backup piece: data files, archive log files Registration
RMAN: restore application to back up, restore data files, set to modify the data file directory structure
RMAN: recover Application log recovery: open to open the database
