For this demonstration we will be using Oracle Database 11gR2 on Linux and disk based backup. One of the first things we want to do is get the Database ID (DBID) from the database in which we will be restoring its backup. You can find the DBID by connecting to the database with RMAN as shown below. If you are unable to connect to the database you can also find the DBID by inspecting the file name of the control file autobackup. For example, c-1239150297-20100427-00, is a control file autobackup. The first group of numbers appearing after the c-, 123915029, is the DBID. When we restore the database we are not going to have the active redo logs from the original database so we want to stop the recovery at the last SCN in the archive logs. We can find the last SCN by querying V$ARCHIVED_LOG. Here we see that the archive logs contain log information up to SCN 1375117. That is our stopping SCN. We can also find the last SCN in our archive logs through RMAN using LIST BACKUP OF ARCHIVELOG ALL. 1 2 3 4 5 6 7 8 9 1 0 1 1 [ o r a c l e @ o r a 1 ~ ] $ r m a n R e c o v e r y M a n a g e r : R e l e a s e 1 1 . 2 . 0 . 1 . 0 - P r o d u c t i o n o n T u e A p r 2 7 0 9 : 4 0 : 3 4 2 0 1 0 C o p y r i g h t ( c ) 1 9 8 2 , 2 0 0 9 , O r a c l e a n d / o r i t s a f f i l i a t e s .

Restore database to another host using RMANby Eric Jenkinson on April 28, 2010
Categories: Backup and Recovery,Oracle Database
Tagged: host, recover, restore, rman
This document will detail the steps to restore a database on a new host using RMAN. For this demonstration we will be
using Oracle Database 11gR2 on Linux and disk based backup.
One of the first things we want to do is get the Database ID (DBID) from the database in which we will be restoring its
backup. You can find the DBID by connecting to the database with RMAN as shown below.
If you are unable to connect to the database you can also find the DBID by inspecting the file name of the control file
autobackup. For example, c-1239150297-20100427-00, is a control file autobackup. The first group of numbers
appearing after the c-, 123915029, is the DBID.
When we restore the database we are not going to have the active redo logs from the original database so we want to stop
the recovery at the last SCN in the archive logs. We can find the last SCN by querying V$ARCHIVED_LOG.
Here we see that the archive logs contain log information up to SCN 1375117. That is our stopping SCN. We can also find
the last SCN in our archive logs through RMAN using LIST BACKUP OF ARCHIVELOG ALL.
Looking through the output above we see that highest Next SCN is 1375117 which is part of backup set 60.
Next we need to make the backup available to the new host. If the backups reside on a shared file system that the new host
has access to then there is nothing more to do. If the backups are on local storage we will need to transfer the backups to
the new host.
All of the rest of the steps will take place on the new host.
Set the ORACLE_SID to the SID of the database that made the backup and start up RMAN and connect to the target.
We now need to set the DBID and bring the database in mount mode. When we bring the database up in mount mode we
will receive errors because the parameter file is not found. This is to be expected as we are restoring to a new host. Oracle
willuseadummyparameterfileforthetimebeing.
Now with the database in mount mode we need to restore the SPFILE. We are going to need to make some changes to the
SPFILE so we will restore SPFILE to a PFILE. The SPFILE is stored in the control file autobackup. All of the RMAN
configuration parameters values are at their defaults so we will need to set the location for the control file autobackup.
Below we will set the location for the control file autobackup and restore the SPFILE to a PFILE and then we shutdown the
database.
Now that we have the SPFILE weneedtoeditthesomeoftheparametertoreflectthenewhostsfilesystemwereappropriate. Below is a list of the some of the parameter you might need to change in your environment. These directories
must exist on the new host.
Note: If you are using 11g you to ensure your kernel parameters are set appropriately to avoid a possible ORA-00845.
After making the necessary changes to the PFILE we now will bring the database back up in NOMOUNT mode so we can
restore the control files. When bringing the database up in NOMOUNT mode we will use the PFILE we edited earlier.
Just like the SPFILE we will use the autobackup to restore the control file after setting the control file autobackup format.
After restoring the control files we mount the database.
Now that the control files have been restored and mounted, all of the RMAN configuration parameters have been set. You
should verify the paths to make sure they are appropriate for this host.
Given the current settings RMAN is going to look in /u03/app/oracle/oradata/orcl/backup for both the control file
autobackups and database/archive log backups. The backup we copied over is located in
/u01/app/oracle/oradata/orcl/backup. There are two ways to resolve this issue. Either move the backup to the
location were RMAN is configured or change the configuration. It may be that moving the backups may not be an option so
we document what needs to be done next.
RMAN has record of a backup in /u03/app/oracle/oradata/orcl/backup but has no record of the backup we have in
/u01/app/oracle/oradata/orcl/backup/. We need remove the record of the old location and the backup of the new
location.
In order to let RMAN know about the backup in /u01/app/oracle/oradata/orcl/backup we use the CATALOG
command.
As a result of the CATALOG command RMAN performed a CROSSCHECK. The backup registered at
/u03/app/oracle/oradata/orcl/backup/ was marked expired as a result of the CROSSCHECK because they were not
present.
We are almost ready to restore the database the last thing to be done is to build the restore script. During the restore we
can change the location of the data files by using SET NEWNAME FOR DATAFILE. The data files in the backup are on
various locations but we would like to restore them to only one.
Also we would like to change the location of the redo logs as well. In order to change the redo log locations the ALTER
DATABASE RENAME FILE command has to be issued. Below are examples of both.
If you remember we stated that we wanted the restore to stop at SCN 1375117 because that was the latest SCN in which
we have archive logs. In order to stop at a specific SCN we will use the SET UNTIL SCN 1375117.
After all of that we just need to restore the database, switch the data files so the control files have the new path and recover
the database. Not much at all.
Below is the entire script to do just that.
The script above was saved to the file restore.rman. Below is the output.
All that is left is to open the database with the RESETLOGS option.

Can we use multiple channels to do the RESTORE ? We have 4tb db and around 800gb of RMAN backup size. We
need 5 channels to be configured.

This is an excellent doc.
What about when I have to restore/duplicate to a different SID. At what point and how to change the name from PROD
to DEV2?

Restore database to another host using RMANby Eric Jenkinson on April 28, 2010
Categories: Backup and Recovery,Oracle Database
Tagged: host, recover, restore, rman
This document will detail the steps to restore a database on a new host using RMAN. For this demonstration we will be
using Oracle Database 11gR2 on Linux and disk based backup.
One of the first things we want to do is get the Database ID (DBID) from the database in which we will be restoring its
backup. You can find the DBID by connecting to the database with RMAN as shown below.
If you are unable to connect to the database you can also find the DBID by inspecting the file name of the control file
autobackup. For example, c-1239150297-20100427-00, is a control file autobackup. The first group of numbers
appearing after the c-, 123915029, is the DBID.
When we restore the database we are not going to have the active redo logs from the original database so we want to stop
the recovery at the last SCN in the archive logs. We can find the last SCN by querying V$ARCHIVED_LOG.
Here we see that the archive logs contain log information up to SCN 1375117. That is our stopping SCN. We can also find
the last SCN in our archive logs through RMAN using LIST BACKUP OF ARCHIVELOG ALL.
Looking through the output above we see that highest Next SCN is 1375117 which is part of backup set 60.
Next we need to make the backup available to the new host. If the backups reside on a shared file system that the new host
has access to then there is nothing more to do. If the backups are on local storage we will need to transfer the backups to
the new host.
All of the rest of the steps will take place on the new host.
Set the ORACLE_SID to the SID of the database that made the backup and start up RMAN and connect to the target.
We now need to set the DBID and bring the database in mount mode. When we bring the database up in mount mode we
will receive errors because the parameter file is not found. This is to be expected as we are restoring to a new host. Oracle
willuseadummyparameterfileforthetimebeing.
Now with the database in mount mode we need to restore the SPFILE. We are going to need to make some changes to the
SPFILE so we will restore SPFILE to a PFILE. The SPFILE is stored in the control file autobackup. All of the RMAN
configuration parameters values are at their defaults so we will need to set the location for the control file autobackup.
Below we will set the location for the control file autobackup and restore the SPFILE to a PFILE and then we shutdown the
database.
Now that we have the SPFILE weneedtoeditthesomeoftheparametertoreflectthenewhostsfilesystemwereappropriate. Below is a list of the some of the parameter you might need to change in your environment. These directories
must exist on the new host.
Note: If you are using 11g you to ensure your kernel parameters are set appropriately to avoid a possible ORA-00845.
After making the necessary changes to the PFILE we now will bring the database back up in NOMOUNT mode so we can
restore the control files. When bringing the database up in NOMOUNT mode we will use the PFILE we edited earlier.
Just like the SPFILE we will use the autobackup to restore the control file after setting the control file autobackup format.
After restoring the control files we mount the database.
Now that the control files have been restored and mounted, all of the RMAN configuration parameters have been set. You
should verify the paths to make sure they are appropriate for this host.
Given the current settings RMAN is going to look in /u03/app/oracle/oradata/orcl/backup for both the control file
autobackups and database/archive log backups. The backup we copied over is located in
/u01/app/oracle/oradata/orcl/backup. There are two ways to resolve this issue. Either move the backup to the
location were RMAN is configured or change the configuration. It may be that moving the backups may not be an option so
we document what needs to be done next.
RMAN has record of a backup in /u03/app/oracle/oradata/orcl/backup but has no record of the backup we have in
/u01/app/oracle/oradata/orcl/backup/. We need remove the record of the old location and the backup of the new
location.
In order to let RMAN know about the backup in /u01/app/oracle/oradata/orcl/backup we use the CATALOG
command.
As a result of the CATALOG command RMAN performed a CROSSCHECK. The backup registered at
/u03/app/oracle/oradata/orcl/backup/ was marked expired as a result of the CROSSCHECK because they were not
present.
We are almost ready to restore the database the last thing to be done is to build the restore script. During the restore we
can change the location of the data files by using SET NEWNAME FOR DATAFILE. The data files in the backup are on
various locations but we would like to restore them to only one.
Also we would like to change the location of the redo logs as well. In order to change the redo log locations the ALTER
DATABASE RENAME FILE command has to be issued. Below are examples of both.
If you remember we stated that we wanted the restore to stop at SCN 1375117 because that was the latest SCN in which
we have archive logs. In order to stop at a specific SCN we will use the SET UNTIL SCN 1375117.
After all of that we just need to restore the database, switch the data files so the control files have the new path and recover
the database. Not much at all.
Below is the entire script to do just that.
The script above was saved to the file restore.rman. Below is the output.
All that is left is to open the database with the RESETLOGS option.

Can we use multiple channels to do the RESTORE ? We have 4tb db and around 800gb of RMAN backup size. We
need 5 channels to be configured.

Restore database to another host using RMANby Eric Jenkinson on April 28, 2010
Categories: Backup and Recovery,Oracle Database
Tagged: host, recover, restore, rman
This document will detail the steps to restore a database on a new host using RMAN. For this demonstration we will be
using Oracle Database 11gR2 on Linux and disk based backup.
One of the first things we want to do is get the Database ID (DBID) from the database in which we will be restoring its
backup. You can find the DBID by connecting to the database with RMAN as shown below.
If you are unable to connect to the database you can also find the DBID by inspecting the file name of the control file
autobackup. For example, c-1239150297-20100427-00, is a control file autobackup. The first group of numbers
appearing after the c-, 123915029, is the DBID.
When we restore the database we are not going to have the active redo logs from the original database so we want to stop
the recovery at the last SCN in the archive logs. We can find the last SCN by querying V$ARCHIVED_LOG.
Here we see that the archive logs contain log information up to SCN 1375117. That is our stopping SCN. We can also find
the last SCN in our archive logs through RMAN using LIST BACKUP OF ARCHIVELOG ALL.
Looking through the output above we see that highest Next SCN is 1375117 which is part of backup set 60.
Next we need to make the backup available to the new host. If the backups reside on a shared file system that the new host
has access to then there is nothing more to do. If the backups are on local storage we will need to transfer the backups to
the new host.
All of the rest of the steps will take place on the new host.
Set the ORACLE_SID to the SID of the database that made the backup and start up RMAN and connect to the target.
We now need to set the DBID and bring the database in mount mode. When we bring the database up in mount mode we
will receive errors because the parameter file is not found. This is to be expected as we are restoring to a new host. Oracle
willuseadummyparameterfileforthetimebeing.
Now with the database in mount mode we need to restore the SPFILE. We are going to need to make some changes to the
SPFILE so we will restore SPFILE to a PFILE. The SPFILE is stored in the control file autobackup. All of the RMAN
configuration parameters values are at their defaults so we will need to set the location for the control file autobackup.
Below we will set the location for the control file autobackup and restore the SPFILE to a PFILE and then we shutdown the
database.
Now that we have the SPFILE weneedtoeditthesomeoftheparametertoreflectthenewhostsfilesystemwereappropriate. Below is a list of the some of the parameter you might need to change in your environment. These directories
must exist on the new host.
Note: If you are using 11g you to ensure your kernel parameters are set appropriately to avoid a possible ORA-00845.
After making the necessary changes to the PFILE we now will bring the database back up in NOMOUNT mode so we can
restore the control files. When bringing the database up in NOMOUNT mode we will use the PFILE we edited earlier.
Just like the SPFILE we will use the autobackup to restore the control file after setting the control file autobackup format.
After restoring the control files we mount the database.
Now that the control files have been restored and mounted, all of the RMAN configuration parameters have been set. You
should verify the paths to make sure they are appropriate for this host.
Given the current settings RMAN is going to look in /u03/app/oracle/oradata/orcl/backup for both the control file
autobackups and database/archive log backups. The backup we copied over is located in
/u01/app/oracle/oradata/orcl/backup. There are two ways to resolve this issue. Either move the backup to the
location were RMAN is configured or change the configuration. It may be that moving the backups may not be an option so
we document what needs to be done next.
RMAN has record of a backup in /u03/app/oracle/oradata/orcl/backup but has no record of the backup we have in
/u01/app/oracle/oradata/orcl/backup/. We need remove the record of the old location and the backup of the new
location.
In order to let RMAN know about the backup in /u01/app/oracle/oradata/orcl/backup we use the CATALOG
command.
As a result of the CATALOG command RMAN performed a CROSSCHECK. The backup registered at
/u03/app/oracle/oradata/orcl/backup/ was marked expired as a result of the CROSSCHECK because they were not
present.
We are almost ready to restore the database the last thing to be done is to build the restore script. During the restore we
can change the location of the data files by using SET NEWNAME FOR DATAFILE. The data files in the backup are on
various locations but we would like to restore them to only one.
Also we would like to change the location of the redo logs as well. In order to change the redo log locations the ALTER
DATABASE RENAME FILE command has to be issued. Below are examples of both.
If you remember we stated that we wanted the restore to stop at SCN 1375117 because that was the latest SCN in which
we have archive logs. In order to stop at a specific SCN we will use the SET UNTIL SCN 1375117.
After all of that we just need to restore the database, switch the data files so the control files have the new path and recover
the database. Not much at all.
Below is the entire script to do just that.
The script above was saved to the file restore.rman. Below is the output.
All that is left is to open the database with the RESETLOGS option.

Can we use multiple channels to do the RESTORE ? We have 4tb db and around 800gb of RMAN backup size. We
need 5 channels to be configured.

This is an excellent doc.
What about when I have to restore/duplicate to a different SID. At what point and how to change the name from PROD
to DEV2?
