RMAN-20505, ORA-0119, ORA-27400 encountered in RMANrecover

This is a RAMN restoration task. The production end is Oracle11.2.0.4RAC, and the data files are stored in the file system. The disaster recovery end is the number of data stored in Oracle11.2.0.4 Single Instance + ASM Mode

This is a RAMN restoration task. The production end is Oracle 11.2.0.4 RAC and the data files are stored in the file system. The disaster recovery end is the number of data stored in Oracle11.2.0.4 Single Instance + ASM Mode

This is a RAMN restoration task. The production end is Oracle 11.2.0.4 RAC and the data files are stored in the file system. The disaster recovery end stores data files in the Oracle11.2.0.4 Single Instance + ASM mode. The repair plan requires the production database to be fully prepared for RMAN and then restored on the disaster recovery end. Because the storage methods of the production end and the disaster recovery end are different and the file paths are different, you must use the set newname method to convert the file paths once for recovery of RMAN on the disaster recovery end.

The execution script is as follows:

Run {
Set newname for datafile 1 to '+ data ';
Set newname for datafile 2 to '+ data ';
Set newname for datafile 3 to '+ data ';

... Over 500 data files

Restore database;
Switch datafile all;
Recover database;
}

When an error occurs during the execution of the recover database, the system prompts that the creation of the IDX_S007.dbf data file No. 545th failed.

RMAN-20505: create datafile during recovery
ORA-0119: error in creating database file '/sgpmdb/oradata/u07/cmsdb/IDX_S007.dbf'
ORA-27400: file create error, unable to create file
HPUX-ia Error: 2: No such file or directory
Additional information: 1
RMAN-11003: failure during parse/execution of SQL statement: alter database recover log file '/orabak/arch/2_147320_666569930.arc'
ORA-00283: recovery session canceled due to errors
ORA-01244: unnamed datafile (s) added to control file by media recovery
ORA-01110: data file 545: '/spgmdb/oradata/u07/cmsdb/idx_s007.dbf'

The cause is as follows:
After the production database is fully standby, some DDL operations are performed, such as adding data files. These new operations are recorded in the archive logs after the full backup (/orabak/arch/2_147320_666569930.arc
). The directory of the production environment cannot be found when the data file is created in the repeat archiving log, so an Error is reported (HPUX-ia Error: 2: No such file or directory)
This file is temporarily recorded in/app/oracle/product/11.2.0/db_1/dbs, but it is only a record in the control file and is not found on the disk.

The record of DATA file No. 545th in the control file is as follows, which is not what we expected + DATA
SQL> select name from v $ datafile where name like '% 545%;

NAME
------------------
/App/oracle/product/11.2.0/db_1/dbs/UNAMED00545

Solution

Run the set newname command in RMAN to change the directory address of the DATA file to + DATA/cmsdb/datafile. Restore the data file again and switch the data file.

Run {
Set newname for datafile '/app/oracle/product/11.2.0/db_1/dbs/UNNAMED00545' to '+ DATA/cmsdb/datafile/IDX_S007.dbf ';
Restore datafile '/app/oracle/product/11.2.0/db_1/dbs/UNNAMED00545 ';
Switch datafile '/app/oracle/product/11.2.0/db_1/dbs/UNNAMED00545 ';
}

It can also be written
Run {
Set newname for datafile 545 to '+ data ';
Restore datafile 545;
Switch datafile 545;
}

The output is as follows:
Executing command: SET NEWNAME

Staring restore at 27--14 14
Using channel ORA_DISK1

Creating datafile file number = 545 name = + DATA/cmsdb/datafile/IDX_S007.dbf
Restore not done: all files read only, offline, or already restored
Finished restore at 27--14 14

Datafile 545 switched to datafile copy
