I have two database instances ( instance_a and instance_b ). Both instances have the following configuration. :
db_recovery_file_dest string U:\FRA
db_recovery_file_dest_size big integer 500G
When i go into the directory U:\FRA i found a directory U:\FRA\instance_a\BACKUPSET also U:\FRA\QMS01DEV\DATAFILE and U:\FRA\QMS01DEV\ONLINELOG
But for instance_b there is nothing created.
When does the database create this file structures ?
It is created by RMAN or by ?
When it is created ?
