Typically, duplicate databases are used for testing. The target database cannot be a standby database. For example, you can duplicate a data tablespace but not the tablespace containing the index for the data, or duplicate a tablespace that contains only one partition of a partitioned table. Excludes the specified tablespace from the duplicate database. When using Oracle Managed Files at the target instance, it is not generally possible to generate valid OMF filenames for the duplicate instance by replacing a substring of the target instance OMF filename. You cannot use SET NEWNAME or CONFIGURE AUXNAME to transform the filenames for the online redo logs on the standby database. Hence, if incremental backups exist, RMAN applies only these backups to the restored files during recovery. The DUPLICATE command does not require non-AUXILIARY channels (that is, normal target database channels).

Take OReilly with you and learn anywhere, anytime on your phone and tablet. Specifies how to convert original datafile names to new datafile names in the standby database. These restrictions apply to all uses of the DUPLICATE command (both for creation of a standby database and creation of a nonstandby duplicate database): The target SCN for a DUPLICATE command cannot be before the most recent OPENRESETLOGS. If duplicating a database on the same host as the target database, do not specify the NOFILENAMECHECK option. You cannot use the same database name for the target and duplicate databases when the duplicate database resides in the same Oracle home as the target. To create a standby database with the DUPLICATE command you must specify the FOR STANDBY option.

Specifies options that apply when creating a duplicate database not intended for use as a standby database. If the target and duplicate databases share the same host, set all *_PATH and *_DEST initialization parameters appropriately so that the target database files are not overwritten by the duplicate database files. See Also: The description in dupOptionList. The auxiliary instance must be started with the NOMOUNT option, and the target database must be mounted or open. RMAN automatically shuts down and restarts the auxiliary instance during duplication.
Use DB_CREATE_FILE_DEST for any datafile names not specifically renamed by SET NEWNAME, and do not specify DB_FILE_NAME_CONVERT. You cannot duplicate OFFLINE NORMAL tablespaces, although you can add these tablespaces manually after duplication. of a target database. For databases in ARCHIVELOG mode, DUPLICATE recovers by default up to the last archived redo log generated at the time the command was executed, or until a time specified with a SET UNTIL clause. The DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT initialization parameters cannot be used to control generation of new names for files at the duplicate which are Oracle Managed Files (OMF) at the target database. must be executed from within the RUN command.

Setting New Filenames Manually: ExampleThis example assumes that the target datafiles are on host1 in directory /h1/oracle/dbs/trgt. Otherwise, RMAN may signal this error: The following restrictions and notes apply when you use the DUPLICATE command with the FOR STANDBY option: All backups and copies located on disk must be available at the standby host with the same path names as in the target host. You can skip all tablespaces in the target database except the SYSTEM tablespace, undo tablespaces, and tablespaces containing rollback segments. You do not want to duplicate read-only tablespaces. Do not attempt to register the standby database in the primary database repository. (LogOut/ If a file in the specification list is not affected by the conversion parameter in DUPLICATE, then you must rename it by other means, such as SET NEWNAME.
The target host and duplicate host have the same file structure. A standby database does not get a new DBID. By using this feature, you can activate the read-only tablespace later. The DUPLICATE FOR STANDBY command creates the standby database by restoring a standby control file, mounting the standby control file, and then restoring and recovering backups of the target datafiles.
Use this option only the same as those in the duplicate database. RMAN does not check for completeness. Refer to the description of logSpec for the legal options. RMAN uses the channel configuration from the target for auxiliary channels in the following circumstances: You have not manually allocated auxiliary channels. If you want the duplicate filenames to be the same as the target filenames, and if the databases are in different hosts, then you must specify NOFILENAMECHECK. You can leave a response, or trackback from your own site. DUPLICATE to previous incarnations is not supported. Note that the. When duplicating Oracle Managed Files and storing the duplicates in an ASM disk group, RMAN uses DB_FILE_NAME_CONVERT or LOG_FILE_NAME_CONVERT to convert the disk group name, and then generates a new, valid filename based on the converted disk group name. Because RMAN is not aware of the different hosts, RMAN cannot determine automatically that it should not check the filenames. You cannot set the DB_NAME parameter in the duplicate parameter file to a value different from the database name specified in the DUPLICATE command. See Also: Oracle Database SQL Reference for CREATE DATABASE syntax. If archived logs have not been backed up, then archived logs must be available at the standby host with the same path names as in the target host. For example, RMAN attempts to duplicate tablespaces taken offline with the IMMEDIATE option. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Backups on tape must be accessible from the standby host. Specify new filenames or convert target filenames for the datafiles and online redo logs when the duplicate filenames must be different from the target filenames (as when duplicating to the same host as the primary). Note that if the duplicate database resides in a different Oracle home from the target, then its database name just has to differ from other database names in that same Oracle home. Make sure that all backups and copies (disk or sbt) on the target host are remotely accessible from the duplicate host. If you do not specify filenames for duplicate online redo logs and datafiles, then RMAN reuses the target datafile names. When creating a standby or duplicate database and using Oracle Managed Files, tempfiles are re-created in the current DB_CREATE_FILE_DEST, either when the database is opened to become a primary, or when it is opened read-only. You must be connected to both the target database and auxiliary instance. Note that backups of the standby database are interchangeable with backups of the primary database. In this example, the NOFILENAMECHECK option is specified because the standby and primary datafiles and logs have the same names. To create additional standby databases, connect to the original primary database and run DUPLICATE FOR STANDBY. Do not use the LOG_FILE_NAME_CONVERT parameter. You cannot use the DUPLICATE command to activate a standby database. Make sure that the archived redo logs are available in the expected location in the new host. The standby database is left mounted after duplication is complete. If no valid backups exist of any tablespace or datafile, then the DUPLICATE command fails. In this case, specify the NOFILENAMECHECK option to avoid an error message. Note that this parameter overrides the initialization parameter DB_FILE_NAME_CONVERT (if it is set). The syntax is the same used in the. OReilly members experience live online training, plus books, videos, and digital content from nearly 200 publishers. If you want the duplicate filenames to be the same as the target filenames, and if the databases are in different hosts, then you must specify NOFILENAMECHECK. All tablespaces taken offline with an option other than NORMAL. Allocates automatic channels for the specific.

Enables a restricted session in the duplicate database by issuing the following SQL statement: Specifies a client-side initialization parameter used by the auxiliary instance. Causes RMAN not to check to see if the target database filenames are There's also live online events, interactive content, certification prep materials, and more. You cannot connect to the standby database and then DUPLICATE FOR STANDBY to create an additional standby database. RMAN recovers the duplicate database up to or before the most recent available archived log: it cannot recover into the online redo logs. If duplicating a database on the same host as the target database, do not specify the NOFILENAMECHECKoption. If the target and duplicate databases reside on different hosts, then you must do one of the following tasks for duplication to be successful: Move backups and disk copies from the target host to the duplicate host to the same location as the target host so that the path names are identical. A standby database, which is a special copy of the primary database that is updated by applying archived redo logs from the primary database. When not using Oracle Managed Files, DB_FILE_NAME_CONVERT is used to convert the tempfile names for the new database. Creates a duplicate database, or a standby database, from the backups This option is necessary when you are creating a duplicate database in a different host that has the same disk configuration, directory structure, and filenames as the host of the target database. You cannot recover the duplicate database to the current point in time, that is, the most recent SCN. Because a duplicate database has a unique DBID, it is entirely independent of the primary database and can be registered in the same recovery catalog as the primary database. Issue one or more ALLOCATE AUXILIARY CHANNEL commands before executing the DUPLICATE command, or CONFIGURE automatic auxiliary channels. Otherwise, RMAN may signal this error: This entry was posted on August 17, 2012 at 4:40 PM and is filed under Advanced. In this case, you must recover the standby database up to at least log sequence 100, or the database signals an ORA-1152 error message because the standby control file backup or copy was taken after the point in time. Specifies one or more patterns to map original to duplicate filenames. To use backups (backup sets or image copies) of the target database to create either of the following: A duplicate database, which is a copy of the target database (or a subset of the target database) with a unique DBID. When duplicating a database that is currently in NOARCHIVELOG mode, recovery occurs with the NOREDO option. For example, you can store the read-only tablespace data on a CD-ROM, then mount the CD-ROM later and view the data. For example, assume that you have a small database located in the /dbs directory of host1: Assume that you want to duplicate the database in machine host2, which has the same file system /oracle/dbs/*, and you want to use the same filenames in the duplicate database as in the primary. Tagged: RMAN. The DUPLICATE command uses backup sets stored on tape to duplicate the target database to database newdb, and recovers it to a point 24 hours ago: Reusing the Target Filenames: ExampleThis example assumes the following: You are restoring to a new host without a catalog. RMAN uses the parameter file at this location, which you must have previously created, to start the duplicated database. View all OReilly videos, Superstream events, and Meet the Expert sessions on your home TV. For example, assume that you create the standby control file and then immediately afterward archive the current log, which has a sequence of 100. The name should match the name in the initialization parameter file of the duplicate database or the database signals an error when creating the control file. When the standby or duplicate database is opened in read-only or read/write mode, Oracle automatically creates temporary files as needed, with the converted names based upon DB_FILE_NAME_CONVERT. Get Mark Richardss Software Architecture Patterns ebook to better understand how to design componentsand how they should interact. To specify different filenames for the tempfiles, see the discussion of SWITCH TEMPFILE . If the auxiliary does not use a server-side parameter file in the default location, you must specify the client-side parameter file that RMAN should use when starting the auxiliary instance. You wish to duplicate the database to newdb on host2 in the directory /h2/oracle/oradata/newdb.
Change), You are commenting using your Facebook account. If you do not specify SKIP TABLESPACE, then RMAN attempts to duplicate the following: All datafiles in online tablespaces, whether or not the datafiles are online. You want to prevent RMAN from checking whether files on the target database that have the same names as the duplicated files are in use. Specifies that RMAN should recover the database after creating it. If the target and duplicate databases reside on the same host, set the CONTROL_FILES parameter appropriately so that the DUPLICATE command does not generate an error because the target control file is in use. You wish to name the duplicate files exactly like the target database files. Specifies options that only apply when creating a standby database.
