Listing Incarnations

A new incarnation of the database is created when you perform the open resetlogs operation. To view the list of database incarnations,

RMAN> List incarnation;

List Summary of Backups

The summary of backups include backupset key, the status, device type, completion time etc,

RMAN> List Backup Summary;
RMAN> List expired Backup of archivelog all summary;
RMAN> List Backup of tablespace Test summary;

List Backups of various files

It provides the summary of the backups available for each datafile, controlfile, archivelog file and spfile.

RMAN> List Backup By File;

f you want the detailed report on the backups, then issue the following command.

RMAN> List Backup;

It lists the all available information about the backups.

Backups used for Recovery

To list the backups used for restore and recovery,

RMAN> list recoverable backup;

Expired Backups

The list backup shows both available and expired backups. To view only the expired backups,

RMAN> List expired Backup;
RMAN> List expired Backup summary;
RMAN> List expired Backup of Archivelog all;
RMAN> List expired Backup of datafile 10;

Listing Tablespace and Datafile Backups

RMAN> List Backup of Tablespace Test;
RMAN> List Backup of Datafile 4;

Listing Archivelog Backups

RMAN> List Archivelog all;
RMAN> List Archivelog all backedup 2 times to device type sbt;

Listing Controlfile and Spfile Backups

RMAN> List Backup of Controlfile;
RMAN> List Backup of Spfile;

The above list commands displayed information about the backusets.
If you have performed Image copy backups then you must use the list copy command as shown below,

RMAN> List Copy;
RMAN> List Copy of database;
RMAN> List Copy of tablespace test;
RMAN> List Copy of archivelog all;
RMAN> List Copy of archivelog from sequence 12345;
RMAN> List Copy of archivelog from sequence 1000 until sequence 1010;
RMAN> List Copy of Controlfile;
RMAN> List Copy of Spfile;

recover database from tag="TAG20051024T1XXXXX" validate;
restore database from tag="XXXXXXXX";

RMAN> SET DBID=228033884;

RMAN> CONNECT TARGET

4. Restore the controlfile from autobackup

% rman trace recocf.log

RMAN> SET DBID=228033884;

RMAN> CONNECT TARGET

RMAN> RUN
{ SET CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE disk TO '/rman/V920/%F';
ALLOCATE CHANNEL d1 DEVICE TYPE disk;
RESTORE CONTROLFILE FROM AUTOBACKUP
MAXSEQ 5 # start at sequence 5 and count down (optional)
MAXDAYS 5; # start at UNTIL TIME and search back 5 days (optional)
MOUNT DATABASE;
}

5. Verify what is available for incomplete recovery.

We will recover to the highest SCN log sequence and thread. We will use the log sequence in this case.

The options are "until time", "until scn", or "until sequence".

* First we need to fine the highest sequence of each thread:

SQL> select max(sequence#) from v$archived_log where thread#=1;

MAX(SEQUENCE#)
--------------
25

SQL> select max(sequence#) from v$archived_log where thread#=2;

MAX(SEQUENCE#)
--------------
13

* Next is to find the thread with highest SCN ( NEXT_CHANGE# )

In this case the SCN is greater in thread 2 sequence 13 than in sequence 25 thread 1. So we will use thread 2. We will set sequence 14 thread 2 for RMAN 'until sequence' recovery, because RMAN stops the recovery before applying the indicated sequence. Log sequence for recovery needs always be sequence+1 to end at +1 after applying the prior sequence.

SQL> select sequence#, thread#, first_change#, next_change#
from v$archived_log
where sequence# in (13,25);

--- SET UNTIL SEQUENCE 14 THREAD 2 ----

6. Get the sentences to add TEMPFILES after opening DB.

Locally Managed Temporary Tablespaces are not restored by RESTORE command, we need to create them manually after recovery is complete.

If using LMT Temporary tablespace the controlfile will have the syntax to add the tempfile after recovery is complete. The following command will give us the create controlfile sencence:

SQL> alter database backup controlfile to trace;

Example:

# Commands to add tempfiles to temporary tablespaces.
# Online tempfiles have complete space information.
# Other tempfiles may require adjustment.
ALTER TABLESPACE TEMP ADD TEMPFILE '/dev/db/rV92B_temp_01.dbf' SIZE 41943040 REUSE AUTOEXTEND OFF;
# End of tempfile additions.
#

7. Run the rman script

Since log sequence 13 thread 2 next_change# is 3 changes ahead of thread 1 sequence 25 we are using sequence 14 to stop recovery. This will restore the data files and recover them completely using the online logs.

run {
SET UNTIL SEQUENCE 14 THREAD 2;
RESTORE DATABASE;
RECOVER DATABASE;
ALTER DATABASE OPEN RESETLOGS;
}

Finally add the tempfiles with sentences from step 6.

# RMAN Format Description
###########################

%a Current database activation id

%A Zero-filled activation ID

%c The copy number of the backup piece within a set of duplexed backup pieces.bMaximum value is 256

%d Database name

%D Current day of the month from the Gregorian calendar in format DD

%e Archived log sequence number

%f Absolute file number

%F Combines the DBID, day, month, year, and sequence into a unique and repeatable generated name

%h Archived redo log thread number

%I DBID

%M Month in the Gregorian calendar in the format MM

%n Database name, padded on the right with x characters to a total length of eight characters

%N Tablespace name. Only valid when backing up datafiles as image copies.

%p Piece number within the backup set. This value starts at 1 for each backup set and is incremented by 1
for each backup piece created. If a PROXY is specified, the %p variable must be included in the FORMAT
string either explicitly or implicitly within %U.

%r Resetlogs ID

%s Backup set number. This number is a counter in the control file that is incremented for each backup set.
The counter value starts at 1 and is unique for the lifetime of the control file. If you restore a backup
control file, then duplicate values can result. CREATE CONTROLFILE initializes the counter at 1.

%S Zero-filled sequence number

%t Backup set time stamp, a 4-byte value derived as the number of seconds elapsed since a fixed reference time.
The combination of %s and %t can be used to form a unique name for the backup set.

%T Year, month, and day in the Gregorian calendar in the format: YYYYMMDD

%u An 8-character name constituted by compressed representations of the backup set or image copy number and the
time the backup set or image copy was created

%U A system-generated unique filename (default). %U is different for image copies and backup pieces.
For a backup piece, %U is a shorthend for %u_%p_%c and guarantees uniqueness in generated backup filenames.
For an image copy of a datafile, %U means the following: data-D-%d_id-%I_TS-%N_FNO-%f_%u

%Y Year in this format: YYYY

%% Percent (%) character. For example, %%Y translates to the string %Y

How To Use RMAN Dynamic Channel Allocation For RAC Environments (Doc ID 1100443.1)

nsnames.ora entry:
RACTEST=
(DESCRIPTION =
(ADDRESS_LIST =
(LOAD_BALANCE = yes)
(FAILOVER = on)
(ADDRESS = (PROTOCOL = TCP)(HOST = <node1>)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = <node2>)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = <node3>)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = RACTEST)
)
)

RMAN connect:
rman target <username>/<password>@RACTEST

The username and password are for a user with SYSDBA privileges.

RMAN channel configuration:
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET PARALLELISM 4;

-- after SCN
SELECT NAME, THREAD#, SEQUENCE#, FIRST_CHANGE#, NEXT_CHANGE#
FROM V$ARCHIVED_LOG
WHERE 556890767466 >= FIRST_CHANGE#

SELECT LF.MEMBER, LF.GROUP#, L.THREAD#, L.SEQUENCE#, L.STATUS, L.FIRST_CHANGE#, L.NEXT_CHANGE#
FROM V$LOG L, V$LOGFILE LF
WHERE LF.GROUP# = L.GROUP#

delete force noprompt archivelog until time 'sysdate-1' ;

delete force noprompt archivelog until time "to_date('2024-10-22 10:30:00', 'yyyy-mm-dd hh24:mi:ss')";

 If we were to query using function SCN_TO_TIMESTAMP to get respective timestamp of a past SCN,
oracle will pick the information from SMON_SCN_TIME table.
SCN that is greater than the MAX SCN that is available in SMON_SCN_TIME table, Oracle will get the results from the SGA.
So, as long as your SCN is between the range of the below o/p, you will get the results successfully or else it will fail with ORA- errors.

SELECT * FROM (SELECT MIN(SCN) FROM SMON_SCN_TIME), (SELECT TO_CHAR(CURRENT_SCN) FROM V$DATABASE);
