Using RMAN Incremental Backups to Roll Forward a Physical Standby Database

In this article, we will show the steps that can be used to resolve problems if a physical standby database has lost or corrupted archived redo data or has an unresolvable archive gap.

1). Check the CURRENT_SCN on Primary and Standby

--On Primary
SQL> select current_scn from v$database;

CURRENT_SCN
-----------
871303

--On Standby
SQL> select current_scn from v$database;

CURRENT_SCN
-----------
859798

2). On the standby database, stop the Managed Recovery Process.
SQL> alter database recover managed standby database cancel;

3). Take "FROM SCN" backup of Primary Database
RMAN> backup incremental from scn 859790 database format '/u01/stnd_backp_%U.bak';

4). Create Standby Controlfile at Primary:
SQL> alter database create standby controlfile as /u01/stnd_cntl.ctl';

5).Copy the backup files and control file to standby server.

scp oracle@192.168.195.128:/u01/stnd* /u01/

At Standby copy controlfiles to their loactaion:

cp stnd_cntl.ctl /u01/app/oracle/oradata/HCLDB/control01.ctl
cp stnd_cntl.ctl /u01/app/oracle/flash_recovery_area/HCLDB/control02.ctl

6). Mount the standby database using backup controlfile.
SQL> startup nomount
SQL> alter database mount standby database;

7).Catalog the backupieces which you have copied from primary server to standby server using below command on standby server.

RMAN> catalog start with '/u01/stnd_backp_0fo4apn7_1_1.bak';
RMAN> catalog start with '/u01/stnd_backp_0go4apov_1_1.bak';

8). Recover the standby database with the cataloged incremental backup.
RMAN> recover database noredo;

**You must also specify NOREDO if the online logs are available but the redo cannot be applied to the incrementals.
**If you do not specify NOREDO, then RMAN searches for redo logs after applying the incremental backup, and issues an error message when it does not find them.

9), Now check whether the standby database is properly synched or not
- On Primary database
SQL> select max(sequence#) from v$archived_log;

- On Standby database
SQL> select max(sequence#) from v$log_history;

10) On the standby database, start the MRP process.
SQL> alter database recover managed standby database disconnect from session;

Step by Step - Physical Standby Setup using DUPLICATE in Oracle Database 11g Release 2

Step by Step - Physical Standby Setup using DUPLICATE in Oracle Database 11g Release 2

My Server Details:-
Primary Database - HCLDB - Sever - 192.168.195.128
Standby Database - HCLDB_STBY - Sever - 192.168.195.138
Oracle 11GR2 on RHEL5

Step1. Make sure your Primary DB is in Archivelog mode and Force logging is enabled if not put you DB in Archivelog mode

SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 1
Next log sequence to archive 2
Current log sequence 2

**Enable forced logging by issuing the following command.

SQL> ALTER DATABASE FORCE LOGGING;

Database altered.

Step2. Check the setting for the DB_NAME and DB_UNIQUE_NAME parameters. In this case they are both set to "HCLDB" on the primary database.

SQL> show parameter db_name

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_name string HCLDB
SQL> show parameter db_unique_name

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_unique_name string HCLDB

Step3. The DB_UNIQUE_NAME values of the primary and standby database should be used in the DG_CONFIG setting of the LOG_ARCHIVE_CONFIG parameter.

SQL> ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(HCLDB,HCLDB_STBY)';

System altered.

Step4. Set suitable remote archive log destinations.

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=HCLDB_STBY NOAFFIRM ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=HCLDB_STBY';

System altered.

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE;

System altered.

Step5. Set LOG_ARCHIVE_FORMAT and LOG_ARCHIVE_MAX_PROCESSES parameters

SQL> ALTER SYSTEM SET LOG_ARCHIVE_FORMAT='%t_%s_%r.arc' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=30;
ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE SCOPE=SPFILE;

Step6. make sure the primary is ready to switch roles to become a standby

SQL> ALTER SYSTEM SET FAL_SERVER=HCLDB_STBY;
ALTER SYSTEM SET DB_FILE_NAME_CONVERT='HCLDB_STBY','HCLDB' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_FILE_NAME_CONVERT='HCLDB_STBY','HCLDB' SCOPE=SPFILE;
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;

Step7. Configure tnsnames on both servers.

>>>> tnsnames.ora entry
-------------------------------------------------------------------
HCLDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.128)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = HCLDB)
)
)

HCLDB_STBY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.138)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = HCLDB_STBY)

)
)
-----------------------------------------------------------------------------

>>>>> listener.ora entry at Primary
------------------------------------------------------------------------------
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = HCLDB)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = HCLDB)
)
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.128)(PORT = 1521))
)
-----------------------------------------------------------------------------------

>>>>>listener.ora entry at Standby
-------------------------------------------------------------------------------------
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = HCLDB_STBY)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = HCLDB_STBY)
)
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.138)(PORT = 1521))
)
---------------------------------------------------------------------------------------

Start listenter on both servers and confirm with tnsping

Step8. Copy the Primary DB init file (initHCLDB) to Standby server and rename the init file to initHCLDB_STBY

scp oracle@192.168.195.128:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initHCLDB.ora /u01/app/oracle/product/11.2.0/dbhome_1/dbs/
cp initHCLDB.ora initHCLDB_STBY.ora

Step9. Create orapwd file at Standby DB
orapwd file=orapwHCLDB_STBY password=oracle entries=10

Step10. Connect to Standby server and start in NOMOUNT stage

[oracle@localhost dbs]$ . oraenv
ORACLE_SID = [HCLDB_STBY] ?
ORACLE_HOME = [/home/oracle] ? /u01/app/oracle/product/11.2.0/dbhome_1/
The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1/ is /u01/app/oracle

Step by Step - Duplicating Oracle Database using RMAN Backup with connection to Target database

Step by Step Duplicating Oracle Database using RMAN Backup with connection to Target database:-
Details:

Oracle EE 11.2 on RHEL5
Target Server: 192.168.195.128
Clone Server: 192.168.195.137

As we are duplicating to a different we can use same SID for both Source and Clone. My source DBID is HCL

Step1. Put your target database in Archive log mode.

Step2. Start RMAN at Target and Configure CONTROLFILE AUTOBACKUP ON
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;

Take Backup of Target database
RMAN> BACKUP DATABASE PLUS ARCHIVELOG

Step3. Configure tnsnames and listener at source and clone server as below:

At Source Server
--------------------------------------------------------------------
HCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.137)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = HCL)
)
)
---------------------------------------------------------------------
At Clone Server
----------------------------------------------------------------------
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = HCL)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = HCL)
)
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.195.137)(PORT = 1521))
)
------------------------------------------------------------------------

Step4: create orapwd file at clone server's dbs directory
orapwd file=orapwHCL password=oracle entries=10

Step5. Create pfile of Target database and copy pfile to Clone Server's dbs directory
SQL> create pfile from spfile;

Copy pfile to Clone Server
scp oracle@192.168.195.128:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initHCL.ora /u01/app/oracle/product/11.2.0/dbhome_1/dbs/

Step6. Create required directories at Clone server. Here I'm using same filesystem as source so no need to use DB_FILE_NAME_CONVERT

mkdir -p /u01/app/oracle/oradata/HCL
mkdir -p /u01/app/oracle/flash_recovery_area/HCL
mkdir -p /u01/app/oracle/admin/HCL
cd /u01/app/oracle/admin/HCL
mkdir adump dpdump

Step7. Copy backupfile to Clone Server from Source Server
scp -r oracle@192.168.195.128:/u01/app/oracle/flash_recovery_area/HCL/ /u01/app/oracle/flash_recovery_area/

Step8. At Remote Server set ORACLE_SID=HCL and start the Clone Server in NOMOUNT mode
SQL> STARTUP NOMOUNT;

Step9: start RMAN at source and connect RMAN to clone as well
At Source
RMAN TARGET /
connect auxiliary sys/oracle@HCL

***Make sure your Souce Database is in OPEN mode and Clone DB is in NOMOUNT Mode

Now run the Duplicate command # See the response as well

RMAN : Recovery of a dropped tablespace

If a tablespace has been dropped, the Tablespace Point In Time Recovery (TSPITR) method cannot be used.

When you drop a tablespace, the controlfile will then no longer have any records of the tablespace which has been dropped. Attempts to use the RMAN RECOVER TABLESPACE command will return the RMAN error RMAN-06019 – “could not translate tablespace name” as shown below.

Step 1. Lets create a tablespace droptest first.
SQL> create tablespace droptest datafile '/u01/app/oracle/oradata/HCL/droptest01.dbf' size 50m;

Tablespace created.

Step 2. Delete this tablespace including contents and datafiles.
SQL> drop tablespace droptest including contents and datafiles;

Tablespace dropped.

Step 3. Now try to recover the dropped tablespace using RMAN
RMAN> recover tablespace droptest;

Starting recover at 18-JAN-13
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=43 device type=DISK
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 01/18/2013 20:43:24
RMAN-20202: Tablespace not found in the recovery catalog
RMAN-06019: could not translate tablespace name "DROPTEST"

RMAN>
See the error - RMAN-20202: Tablespace not found in the recovery catalog

Step 4. So to recover the dropped tablespace, we have two options:
1) Do a point in time recovery of the whole database until the time the tablespace was dropped.
2) Create a clone of the database from a valid backup, export the required tables from the tablespace which has been dropped, recreate the tablespace and then import the tables from the clone.

The first option will require the outage of the entire database and the entire database will be rolled back in tine in order to recover the tablespace.The second option can be peformed online, but we will need to factor in the disk space requirements to create a clone of the database from which the tablespace has been dropped.

Step 5. Lets create the same tablespace again and take a full backup of database including controlfile.

SQL> create tablespace droptest datafile '/u01/app/oracle/oradata/HCL/droptest01.dbf' size 50m;

Tablespace created.

Take full backup.

RMAN> backup database plus archivelog;

Drop the tablespace DROPTEST again and we will recover it as below.

Step 6. Start the database in nomount stage and restore the controlfile from backup.
SQL> startup nomount
ORACLE instance started.

Variable Size 394265604 bytes
Database Buffers 230686720 bytes
Redo Buffers 5623808 bytes

Step 7. Next We need to restore controlfile from backup which contains metadata of tablespace DROPTEST.

RMAN> restore controlfile from autobackup;

Starting restore at 18-JAN-13
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=17 device type=DISK

channel ORA_DISK_1: restoring control file from AUTOBACKUP /u01/app/oracle/flash_recovery_area/HCL/autobackup/2013_01_18/o1_mf_s_805064205_8hltfpnt_.bkp

output file name=/u01/app/oracle/flash_recovery_area/HCL/control02.ctl

Now restored controlfile contains the metadata of dropped Tablespace DROPTEST.

RMAN> report schema;

The alert log will also show the time when the tablespace was dropped. We can also see that a controlfile autobackup has taken place after the tablespace was dropped

drop tablespace droptest including contents and datafiles
Deleted file /u01/app/oracle/oradata/HCL/droptest01.dbf

Step 7.Now that we know the time the tablespace was dropped, we can do a point in time recovery of the DATABASE in order to recover the tablespace which has been dropped.

RMAN> run {
