Managed the LIST and REPORT commands
RMAN-Managed the LIST and
REPORT commands
Introduction
As a DBA, you are
responsible for obtaining backup information using the LIST and REPORT
commands. Your job"s responsibilities dictate that you should at
least be informed of the following basic fundamental subjects:
Performing the LIST and
REPORT commands
Creating a RMAN script
Replacing a RMAN script
Deleting a RMAN script
Running a RMAN script
Connecting to the RMAN tool
using the Recovery Catalog database
Listing all of the backup
sets and the associated backup pieces
Listing all of the expired
backup sets
Listing the backup of the
data files for a tablespace
Listing a database
incarnations registered in a database
Displaying objects that
need a backup and a confirmed retention policy
Listing all of the backup
sets and image copies that are OBSOLETE
Listing all of the schemas
of the database that can be deleted
Commands:
RMAN> CONNECT CATALOG
RMAN> CONNECT TARGET
RMAN> LIST BACKUP;
RMAN> LIST EXPIRED
BACKUPSET;
RMAN> LIST BACKUP
RMAN> LIST INCARNATION
OF DATABASE;
RMAN> REPORT NEED
BACKUP;
RMAN> REPORT OBSOLETE;
RMAN> REPORT SCHEMA;
RMAN> RUN
RMAN> REPLACE SCRIPT
RMAN> DELETE SCRIPT
RMAN> exit;
Hands-on
In this exercise we will
learn how to perform the LIST and REPORT commands in the RMAN tool.
Also, we'll learn how to create, replace, delete, and run a RMAN
script.
First, let's connect to the SCHOOL database as the SYSTEM/MANAGER
user.
SQL> CONNECT system/manager
Run the RMAN tool.
DOS> RMAN
Connect to the RMAN tool using the Recovery Catalog database.
RMAN> CONNECT CATALOG
RMAN/password@dbs4RMAN
Connect to the target database.
RMAN> CONNECT TARGET system/manager@school
LIST command
List all of the backup sets and the associated backup pieces.
RMAN> LIST BACKUP;
List all of the expired backup sets.
RMAN> LIST EXPIRED BACKUPSET;
List the backup of the data files for the TOOLS tablespace.
RMAN> LIST BACKUP OF TABLESPACE tools;
List the database incarnations registered in the database.
RMAN> LIST INCARNATION OF DATABASE;
REPORT command
Display the objects that need a backup and confirm the retention
policy.
RMAN> REPORT NEED BACKUP;
List all of the backup sets and image copies that are OBSOLETE and can
be deleted.
RMAN> REPORT OBSOLETE;
List all of the schemas of the database that can be deleted.
RMAN> REPORT SCHEMA;
Create a script
Create a RMAN script and name it BACKUP_TOOLS, since it is backing
up only the TOOLS tablespace.
RMAN>
CREATE SCRIPT backup_tools
{
BACKUP TABLESPACE tools;
}
Execute a script
Run the BACKUP_TOOLS script.
RMAN> RUN {EXECUTE SCRIPT backup_tools;}
Modify a script
Change or replace the BACKUP_TOOLS script to not only back up the
TOOLS tablespace, but also back up the archive log files.
RMAN>
REPLACE SCRIPT backup_tools
{
BACKUP TABLESPACE tools PLUS ARCHIVELOG;
}
Delete a script
Delete the BACKUP_TOOLS
script.
RMAN> DELETE SCRIPT backup_tools;
Exit the RMAN.
RMAN> exit;

"Read, every day,
something no one else is reading. Think, every day, something no
one else is thinking. Do, every day, something no one else would
be silly enough to do. It is bad for the mind to be always part
of unanimity." Christopher Morley (1890 - 1957) |
