Rman encryption and other techniques

Today I will demonstrate Recovery Manager features, especially encryption and some other techniques. First of all let me note about RMAN backup encryption. Staring from Oracle 10g RMAN now creates encrypted backups that cannot be restored by unauthorized people. There are 3 modes of backup encryption: * Transparent encryption * Password encryption * Dual-mode encryption using either transparent or password encryption All RMAN backups are not encrypted but you can encrypt any RMAN backup in the form of a backup set. In this tutorial I will show you how to configure Password encryption. Let`s finish talking and start to demonstrate. check parameters with "SHOW ALL" command, by default encryption is OFF RMAN> show all; RMAN configuration parameters are: CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default CONFIGURE BACKUP OPTIMIZATION OFF; # default CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default CONFIGURE CONTROLFILE AUTOBACKUP ON; CONFIGURE CONTR...

ORA-03206: maximum file size of (5242880) blocks in AUTOEXTEND clause is out of range

Today when I want to change max size of datafile I got strange error. ALTER DATABASE DATAFILE '/u01/app/oracle/oradata/MYDB/users01.dbf' AUTOEXTEND ON NEXT 1280K MAXSIZE 32GB ORA-03206: maximum file size of (5242880) blocks in AUTOEXTEND clause is out of range Here is reason: The maximum file size for an autoextendable file has exceeded the maximum number of blocks allowed. After research internet I found that instead of using 32GB we can use 32767M. (same values but in MB). Or you may use 31GB too. ALTER DATABASE DATAFILE '/u01/app/oracle/oradata/MYDB/users01.dbf' AUTOEXTEND ON NEXT 1280K MAXSIZE 32767M;
