We can also specify where we want the RMAN backups to be created. This parameter specifies how many full or level zero backups of each data file and control file RMAN should keep, that is if the number of full or level zero backups for a specific data file or a control file exceeds the redundancy setting, then RMAN consider those extra backups as obsolete and can delete them upon user's request. full resync complete, RMAN> report schema; CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/12.2.0/dbhome_1/dbs/snapcf_prodserver.f'; # default. 10-SEP-17 10-SEP-17 new RMAN configuration parameters are successfully stored CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default Thanks for putting it up together and sharing it with DBA fraternity.. recovery catalog created.

Database log mode Archive Mode --------- A FORMAT can be specified for each subclause in the BACKUP DATABASE PLUS ARCHIVELOG command. CONFIGURE CONTROLFILE AUTOBACKUP ON; To view these different RMAN configuration options, we'll first have to open the RMAN command line prompt and have RMAN connect to our target database, that is the database we wish to back up or recover and just as a quick reminder, remember that if you are using the Oracle-supplied virtual machine for the exercises in this course, you will have to unset the TWO_TASK parameter before you can continue, so type export TWO_TASK in capital letters equals and type enter. ARCHIVELOG, SQL> archive log list We need to understand some of those different configuration options before we can start running RMAN database backups. Pressing enter will connect RMAN to the Oracle instance running locally on this VM. 2022, OReilly Media, Inc.

Control file: It contains registered target database information at server level itself & RMAN utility directly connects to target database by command RMAN target /. 1 820 SYSTEM YES /u01/app/oracle/oradata/prodserver/system01.dbf This parameter specify that when running RMAN backups without explicitly specifying a destination for the backup sets, RMAN will create and store the backups on a disk instead of a tape device. =============== So, let's copy this command and paste it into our RMAN prompt. PLUS ARCHIVELOG REPORT SCHEMA COMPLETED 0 Following that, we can also specify the name and the path of the control file auto backup using the control file auto backup format parameter. Step 6:To enable backup optimization run the following command, by default backup optimization has been configured OFF. This is often what database administrators choose to do but we can override this default RMAN destination and configure what is known as a new RMAN channel which is the RMAN terminology for specifying a destination for our backups. Step 11:Connect to RMAN on target and recovery catalog database. For example, you might implement a stand-by database in your environment, which might require you to modify the database configurations related to RMAN. CONFIGURE CONTROLFILE AUTOBACKUP ON; ------- ------- -------- ---------------- --- ---------- ---------- The next parameter we'll discuss is the configure default device type to disk parameter. 7 5 USERS NO /u01/app/oracle/oradata/prodserver/users01.dbf RMAN will use a number of default settings in the course of executing the commands Get Oracle Database 12c Oracle RMAN Backup & Recovery now with the OReilly learning platform.
