set newname for database to file system


Here is the list of This section explains how to specify names for the duplicate files when the following condition is true: The source and auxiliary hosts either use different directory structures or use the same structure but you want to name the duplicate files differently. Assume that the source database prod is on host1 and stores its data files in a non-ASM file system. Oracle recommends that you use a server parameter file at the duplicate database when using control files in an OMF format. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. The following example shows a sample initialization parameter file. With the following query, you keep the same path and name as on the original target. Example 26-1 Duplicating from a File System to ASM (Active). When using SET with FOR DATABASE or FOR TABLESPACE, however, you must use at least one of these substitution variables described in Table 26-1: %b, %f, %U. Remote Assume that you want to specify a subset of tablespaces for duplication. Read: How to Restore RMAN Backup with a Different Database Name. Now migrate control files using RMAN. Substitution Variables for SET NEWNAME :, %b = Specifies the file name without the directory path *NEW*, %f = Specifies the absolute file number of the data file for which the new name is generated, %U = Specifies a system-generated file name of the format: data-D-%d_id-%I_TS-%N_FNO-%f, Thank you for reading.This is Airy ..Enjoy, Your email address will not be published. See Oracle Database Backup and Recovery Reference for details on this restriction. Table 26-6 explains DUPLICATE command options for specifying subsets of tablespaces for the duplicate database.

For example to rename a specific data file use SET NEWNAME FOR DATAFILE, It is also possible to rename all datafiles using SET NEWNAME FOR DATABASE. Excludes the specified tablespaces from the duplicate database. %N: Specifies the tablespace The new file names in +DISK2 are generated by ASM and do not match the original file names in disk group +DISK1. "Step 4: Making Backups Accessible to the Duplicate Instance" recommends using the shared disk technique to make backups available to the auxiliary instance. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Restore database to another host using RMAN (sameversion), ORA-12906: cannot drop default temporarytablespace. Performance Tuning Specifies the file name stripped of directory paths. Lets check if logfile are added to new location. is the registered trademark of Oracle Corporation. Table 26-2 shows the results from previous example. eg: You are restoring or duplicating the target database to a new host using RMAN. Lets drop active and inactive members from each group. publish In my backup concept, Ido a manual backup of the spfile and the controlfile at the end of every backup and name it like this, so it`seasy to find.

Support, SQL TuningSecurityOracle The strategy that you use depends on whether the source and duplicate databases use Oracle Managed Files (OMF) or Oracle Automatic Storage Management (ASM). executing command: set newname Converts the file name of a new log file on the primary database to the file name of a log file on the standby database. FormsOracle The Oracle of Set this parameter if you want a multiplexed copy of the control file and online redo log file in the recovery area. Assume that you maintain two hosts, srchost and dsthost. When creating a duplicate database that uses Oracle Managed Files, you must set initialization parameters in the auxiliary instance. The following sections discuss requirements for creating a duplicate database when some or all files of the duplicate database use OMF or ASM. Table 26-5 Auxiliary Instance Initialization Parameters. strive to update our BC Oracle support information. If the source database parameter file contains a value for the DB_BLOCK_SIZE initialization parameter, then you must specify the same value for the auxiliary instance. Oracle PostersOracle Books set newname for database to /u01/app/oracle/product/11.2.0/data/TEST/datafile/%U; (Datafile_Location) are used: RMAN> run Omitting this parameter allows the database to generate valid Oracle managed online redo log file names. ApplicationsOracle Step 2. Using set newname for datafile to NEW will generate a new OMF filename for the restored datafile.

command as follows: RMAN> run If the source data files use OMF, then you cannot rename them using DB_FILE_NAME_CONVERT. ?. The following example illustrates a script that specifies new names for data files 1 through 5 and temp file 1. Now the control files are also migrated to ASM, lets migrate datafiles now. Set these parameters (_1, _2, and so on) only if you want to multiplex the control files and online redo log files in multiple locations. { Table 26-5 describes a subset of the possible initialization parameters. RMAN will create a new tempfile with a specified name after the document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Address: Building no. The script does not set a new name for data file 6 because it is in the TOOLS tablespace, which is excluded from the duplicate database. If multiple parameters are set, then one control file and one online redo log is created in each location. The only Oracle Managed Files in the source database are the data files in the users tablespace. Do not set this parameter if you want the duplicate database control files in an OMF format. tempfiles in a database. Omitting this parameter enables the database to generate valid Oracle managed file names for the duplicate data files. Table 26-4 Initialization Parameter Restrictions for Oracle Managed Files. To generate set newname commands to point to an ASM volume execute the sql below. For example, set DB_CREATE_FILE_DEST, DB_CREATE_ONLINE_DEST_n, and CONTROL_FILES to +DISK1. (%I and %N are optional. STAMP=728496167 To specify a subset of tablespaces for a duplicate database: Ensure that you have completed Steps 1 through 4 in "Basic Steps of Database Duplication". Example 26-5 Including Specified Tablespaces. You can override the default for specific files using SET NEWNAME, as described in "Using SET NEWNAME to Create OMF or ASM Files".

This will avoid the manual entry or vi/notepad editing of similar output. It prepares a name mapping for subsequent operations. The SWITCH command causes the control file to be updated with the new location. The same name used in the DUPLICATE command. You cannot use the DB_FILE_NAME_CONVERT clause of the DUPLICATE command to control generation of new names for files at the duplicate instance that are in the Oracle Managed Files (OMF) format at the source database instance. The DBID can be obtained from another copy of the database using the following query: The SET NEWNAME statement is used to specify that data files etc should be relocated by the RESTORE command. Generate set newname command for each data file individually. For example, you may plan to generate reports that require only a subset of tablespaces from your source database. See Oracle Database Reference provides more information about these parameters. Ernst-Melchior-Gasse 24/DG, 1020 Wien "Step 2: Choosing a Strategy for Naming Duplicate Files" explains the recommended strategy of using the same names for the duplicate and source database files.

Oracle In this demonstration Oracle RDBMS version is 12.1.0.2 and Grid Infrastructure is also 12.1.0.2. If you are duplicating a pluggable database (PDB), then use the PLUGGABLE DATABASE syntax of the BACKUP COPY OF command to copy only the backups of the PDB. e-mail: Burleson Consulting 5. You can also specify DB_FILE_NAME_CONVERT on the DUPLICATE command itself. ), Table 26-1 Substitution Variables for SET NEWNAME.

After connecting to the target, duplicate, and catalog databases, run the RMAN script shown in Example 26-2 to duplicate the database.

You want to store the data files for dupdb in ASM. If you use the SPFILE clause of DUPLICATE to name the files, then you can set initialization parameters in the SPFILE clause. 3> set newname for tablespace users to '/tmp/db/%u'; The auxiliary channel can search for backups in /dsk2/dup on the destination host and restore them. The following example uses one SET NEWNAME command to name all data files in the tablespace users.

unique filename. A more efficient way is to use the SET NEWNAME clause to specify the default name format for all data files in a named tablespace and all data files in the database (rather than setting file names individually, which was in database versions prior to Oracle Database 11gR2 (11.2). examples. To create an initialization parameter file when not planning to use the SPFILE clause: Use an operating system utility to make a copy of the initialization parameter file of the source database in the operating system-specific default location. Using vi global search and replace you can change the path to the new directory using %s. Oracle stamp=728496242 If database is open then put data file offline then do this:. }.

For example, if data file 2 is duplicated, then %f generates the value 2. It can also be used to produce names for data files and temp files. Oracle Real Application Cluster (Oracle RAC) parameters: Set these parameters for each instance of the Oracle RAC database. In this case, RMAN automatically catalogs the backups in the new location. For example, enter the following commands at the RMAN prompt to specify names for files data files 1 through 5: For example, enter the following command at the RMAN prompt: RMAN uses the CONFIGURE AUXNAME settings to name data files 1 through 5. the most difficult Oracle performance and recovery issues.

(adsbygoogle=window.adsbygoogle||[]).push({}); When you must restore the database the same directory structure is not always available. Note the use of the %b wildcard which matches the base name of every file in the source directory. Table 26-6 Options to Specify Subsets of Tablespaces for the Duplicate Database, Excludes the data files of read-only tablespaces from the duplicate database. To transfer the backups from the source host to the destination host: Create a directory in the source host that has the same name as the directory on the destination host that will contain the backups. RMAN> run the usage of these options and substitution variables in real 2. Catalog As default, RMAN restores a backup of a datafile to its default Use an operating system utility to copy the backups in /dsk1/bkp on the source host to /dsk2/dup on the source host. By using the %U variable, you can get the system-generated You want to duplicate the source database to database dupdb on remote host host2. Lets check the Name and Version of the database. Run the DUPLICATE command with one or more of the options in Table 26-6. This scenario assumes that the source database does not currently use a server parameter file or RMAN cannot restore a backup server parameter file. This chapter contains the following topics: Specifying Alternative Names for Duplicate Database Files, Making Disk Backups Accessible Without Shared Disk, Duplicating a Database When No Server Parameter File Exists, Starting the Auxiliary Instance When No Server Parameter File Exists, Duplicating a Subset of the Source Database Tablespaces. Feel free to ask questions on our "Using Non-ASM Storage" discusses the details and options of OMF-managed data files. Performance Tuning. Here Im assuming you already have up and running ASM instance with +DATA and +FRA ASM diskgroups. Change), You are commenting using your Twitter account. This block size must match the block size of the source database. To start the auxiliary instance in preparation for database duplication: Copy the text-based initialization parameter file to the default location on the host containing the SQL*Plus client. Oracle Moreover, these new options come with new substitution The included tablespaces must be self-contained and the resulting skipped tablespaces must not contain SYS objects or materialized views. location. 5> } Do not specify LOG_FILE_NAME_CONVERT if you set Oracle Managed Files initialization parameters. If you are using DUPLICATE to create a standby database, then the name must be the same as the primary database. On the source host, copy the backups to the directory created in the previous step, and then catalog the backups. All rights reserved by Now restore the controlfiles and mount the database: If the backup destination changed from that stored in the controlfiles, you have to catalog the DB backup from this new destination: Because of the new location of all the datafiles, you can use set newname for database and then restore all the files toit: The variable %b is a substitution and is explainedas, ONTEC AG It is not always necessary to duplicate all tablespaces of a database. Bu blogu takip etmek ve yeni gnderilerle ilgili bildirimleri e-postayla almak iin e-posta adresinizi girin. Example 26-3 shows how to skip read-only tablespaces. For example, use the BACKUP COPY OF DATABASE command to copy the backups in /dsk1/bkp on the source host to /dsk2/dup on the source host. If an online redo log file exists at the named location and is of the correct size, then it is reused for the duplicate. When you specify LOG_FILE_NAME_CONVERT, RMAN uses the REUSE parameter when creating the online redo logs. channel ORA_DISK_1: restoring datafile 00004 to /tmp/datafile4.dbf. This works in much the same way as the DB_FILE_NAME_CONVERT and can transform target file names from log_* to duplog_*. When using SET NEWNAME FOR DATAFILE, you can specify a full path as a literal, as in /oradata1/system01.dbf. The resulting set of skipped tablespaces must not have undo segments or materialized views. 911RAC Start the auxiliary instance in NOMOUNT mode, using the text-based initialization parameter file: Copy the text-based initialization parameter file for the auxiliary instance to the same host as the RMAN client used to perform the duplication. This option is also used with one of the 3> set newname for tablespace users to '/tmp/db/%n_%f_%b'; datafiles and tempfiles. Assume that you perform backup-based duplication with a target connection, but no recovery catalog connection. { Database Support Oracle Database Backup and Recovery Reference, Oracle Automatic Storage Management Administrator's Guide, "Step 2: Choosing a Strategy for Naming Duplicate Files", "Using SET NEWNAME to Create OMF or ASM Files", "Settings and Restrictions for OMF Initialization Parameters", "Using SET NEWNAME to Name File System Data Files and Temp Files", "Step 4: Making Backups Accessible to the Duplicate Instance", "Step 7: Creating an Initialization Parameter File and Starting the Auxiliary Instance", "Using DB_FILE_NAME_CONVERT to Generate Names for Non-OMF or ASM Data Files", "Using LOG_FILE_NAME_CONVERT to Generate Names for Non-OMF or ASM Log Files". Scripting on this page enhances content navigation, but does not change the content in any way. See Table 26-1 to learn about options for naming duplicate files. Specifies the default location for Oracle managed data files. When the RESTORE command executes, the users01.dbf data file is restored to /disk2/users01.dbf. As shown in Table 26-1, one way to name duplicate data files is to use the SET NEWNAME command before executing the DUPLICATE command.

of a datafile, %U: Specifies system generated unique It is written there, but the control file is still not pointing to that location. Unlike the SKIP TABLESPACE option, which specifies which tablespaces to exclude from the duplicate database, this option specifies which tablespaces to include and then skips the remaining tablespaces. to avoid name collisions, specify at least one of the substitution variables in the SET NEWNAME command: %b, %f, or %U. output file name=/tmp/db/data_d-test_ts-users_fno-4 recid=10 SQL ALTER TABLESPACE users OFFLINE IMMEDIATE; SET NEWNAME FOR DATAFILE /u01/app/oracle/oradata/ORCL/users01.dbf TO /u02/users01.dbf ; SQL ALTER DATABASE DATAFILE 4, 5 OFFLINE; SWITCH DATAFILE ALL; # UPDATE CONTROL FILE WITH NEW FILE NAMES. Specifies one or more names of control files, separated by commas. database is recovered and opened. Do not set this parameter. The datafiles are not OMF files and you want to make them OMF. RMAN uses the DBID to identify automatic controlfile backup files. Learn how your comment data is processed. In my case my all production data files are available below location. In the example given below, the SET NEWNAME command defines the location where a restore operation of that data file will be written.

If you try to restore the database on another server using RMAN and the directory structure is different, you can use the below query for restoration. You can use the TABLESPACE option to specify which tablespaces to include in the specified database.

Set this parameter to the location for the Oracle Managed Files. If you find an error Required fields are marked *. You can use either of the following approaches: Connect RMAN to the source database as TARGET and use the BACKUP command to back up the backups, as explained in "Backing Up RMAN Backups". When recreating a database it is necessary to specify the DBID.

Prior to Oracle 11gR2, this command was used to rename the the directory that it locates. When NFS or shared disk is not an option, then the path that stores the backups must exist on both the source and destination hosts unless the BACKUP LOCATION option is used for the DUPLICATE command without a target or recovery catalog connection. 1. You cannot exclude the SYSTEM and SYSAUX tablespaces, tablespaces with SYS objects, undo tablespaces, tablespaces with undo segments, tablespaces with materialized views, or tablespaces in such a way that the duplicated tablespaces are not self-contained. Oracle Server 9, Candor TechSpace, IT/ITES SEZ, Tikri, Sector 48, Gurugram, Haryana-122018 Remote DBA Services For information on the supported variables, see supportedOracle Redirected Restore File Name Variablesvariable. The following example illustrates a script that specifies literal names for data files 1-5. In this case, you must start the auxiliary instance with a text-based initialization parameter file. Therefore, you do not have to specify options to exclude these tablespaces. If using multiple directories you can split the output to change the path all in a file then merge the files or find a quicker method. Look at the following example: RMAN> run { Then you have to edit the pfile/spfile for the new location of the controlfiles. 2> { The SET UNTIL statement specifies an SCN at which recovery should stop. In the DUPLICATE command, set PARAMETER_VALUE_CONVERT to convert all directory locations from +DISK1 to +DISK2. Change). set newname for datafile 4 to '/tmp/datafile4.dbf'; 5> } RMAN backup as copy is one of the methods of migrating database from File System to ASM. Ion ), Facebook Burleson Consulting

run If necessary, change other initialization parameters, including the parameters that enable you to connect through Oracle Net, as needed. Required if this initialization parameter is set in the source database. Starting from 11.2, we can use SET NEWNAME FOR DATABASE clause to avoid using SET NEWNAME for individual datafiles. In this scenario, you do not use OMF naming for your files and you want to continue to control the datafile names. Table 26-3 describes the relevant parameters and recommended settings and Table 26-4 lists the restrictions on setting other initialization parameters, Table 26-3 Initialization Parameters for Oracle Managed Files. The following command uses a single SET command to name all data files in the database. In the copied initialization parameter file, manually change DB_NAME to the name of the duplicate database. output file name=/tmp/db/data_d-test_ts-users_fno-5 recid=11 Example 26-2 Duplicating from ASM to ASM (Active). (LogOut/ SupportApps Excel-DB, Expert Oracle Database Tips by Donald BurlesonMarch 25, 2015. In contrast, you must reissue the SET NEWNAME command every time you execute the DUPLICATE command. To use SET NEWNAME to specify new file names: Follow Steps 1 through 4 in "Basic Steps of Database Duplication". Were done with migrating logfiles as well. Wanted! For example, use FTP to transfer the backups in /dsk2/dup on the source host to /dsk2/dup on the destination host. Do not set this parameter. In the following example, the %b, %N and %f variables

Theyre added, now lets drop old logfiles from file system. Errata? Automatically includes the SYSTEM, SYSAUX, and undo tablespaces. The directory /dsk1/bkp is in use on the destination host, so you intend to store backups in /dsk2/dup on the destination host. See "Using LOG_FILE_NAME_CONVERT to Generate Names for Non-OMF or ASM Log Files". This location is also the default location for Oracle managed control files and online logs if no DB_CREATE_ONLINE_LOG_DEST initialization parameters are specified. To perform this operation, your database should be in nomount mode. For example, you can change the target file name from /oracle/ to /dup/oracle/. UpgradesSQL
