Recent development in order not to affect the use of the library, intended to create a backup copy library, updated regularly, to prevent the development of the case can not use the library, you can temporarily use the standby database does not affect the progress.
Environment:
11.2.0.4 single-instance database.
Bank 1 is the source library (target), Library 2 is prepared by the library (auxiliary)
Operating procedure:
1. Library 1 performs a full database backup

released channel: dup
2. Library 1 backup control file
SQL> alter database backup controlfile to '/home/oracle/duplicate/control.ctl';
Database altered.
3. The backup set (1) copy to the library the same path 2, ie, / home / oracle / duplicate, this time produced three documents:
al_t902681874_s12_p1
df_t902681834_s10_p1
df_t902681870_s11_p1
4. Copy the file vault inittest.ora parameter 1 to 2 library, and follow the path to the configuration of the control files, control files (2) can be directly copy the library 1 to 2 lower reservoir corresponding path, including the file name and the need to maintain profile consistent with the general definition:
* .control_files = '/ U01 / app / oracle / 11.2.0.4 / oradata / test / control01.ctl', '/ u01 / app / oracle / 11.2.0.4 / fast_recovery_area / test / control02.ctl'
Create a folder:
/u01/app/oracle/11.2.0.4/oradata/test
/u01/app/oracle/11.2.0.4/fast_recovery_area/test
/u01/app/oracle/11.2.0.4/admin/adump(/bdump/cdump/dpdump/udump)
5. 2 Start nomount state library
SQL> startup nomount pfile = '/ u01 / app / oracle / 11.2.0.4 / dbhome_1 / dbs / initdep.ora';
ORACLE instance started.

Still being given, suggesting:
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/app/oracle/11.2.0.4/oradata/dep/system01.dbf'
View both the error:
[Oracle @ testvm001 dbs] $ oerr ora 1152 01152, 00000, "file% s was
not restored from a sufficiently old backup "
* Cause: An incomplete recovery session was started, but an
insufficient number of logs were applied to make the database
consistent. This file is still in the future of the last log applied.
The most likely cause of this error is forgetting to restore the file
from a backup before doing incomplete recovery.
* Action: Either apply more logs until the database is consistent or> restore the database file from an older backup and repeat
recovery.
[Oracle @ testvm001 dbs] $ oerr ora 1110 01110, 00000, "data file% s: '% s'"
* Cause: Reporting file name for details of another error.
The reported name can be of the old file if a data file
move operation is in progress.
* Action: See associated error message.

Exactly the same information and library 1 2 15. Log database, users, objects, and so on.
To sum up:
1.RMAN need to perform restore the database in mount state.
2. The first target of control can copy the control file to the same path auxiliary library, you need to pay attention to controlling the file path and other file parameters defined in the file folders are created in advance in the auxiliary library, if the advance control files are copied to auxiliary library under the corresponding path, you do not need to restore control, it is equivalent to not have done this operation.
3.resetlogs tips ORA1152 wrong, we need to restore the corresponding archived log, according to projections seq number copied archive log file name.
