In which three situations must you use a recovery catalog? advantage of a stored script is that it is available to any RMAN client that can connect to the target database and recovery catalog. Command files are only available if the RMAN client has access to the file system on which they are stored. are connected to this target database. A global stored script can be run against any database registered in the recovery catalog. the command: control file before they are candidates for being overwritten. Thus, you must ensure that you resynchronize the recovery catalog with the control file records before these records are erased. https://docs.oracle.com/database/121/BRADV/rcmreprt.htm#BRADV90911
A.
when you want to store RMAN global scripts that can be used across multiple databases
B.
when you want to restrict the amount of space used by backups
C.
when you want to perform incremental backups by using a block change tracking file
D.
when you want to list data files that were in a target database at a given time by using the AT clause with the REPORT SCHEMA command
E.
when you want to maintain backup metadata longer than the period specified by the CONTROL_FILE_RECORD_KEEP_TIME parameter
Explanation:
A: Some RMAN features function only when you use a recovery catalog. For example, you can store RMAN scripts in a recovery catalog. The chief
A local stored script is associated with the target database to which RMAN is connected when the script is created, and can only be executed when you
D: If you use a recovery catalog, then you can use the atClause to specify a past time, SCN, or log sequence number, as shown in these examples of
RMAN> REPORT SCHEMA AT TIME ‘SYSDATE-14’; # schema 14 days ago
RMAN> REPORT SCHEMA AT SCN 1000; # schema at scn 1000
RMAN> REPORT SCHEMA AT SEQUENCE 100 THREAD 1; # schema at sequence 100
RMAN> REPORT SCHEMA FOR DB_UNIQUE_NAME standby1;
E: The CONTROL_FILE_RECORD_KEEP_TIME initialization parameter determines the minimum number of days that records are retained in the
