ORA-01111 name for data file 10 is unknown

Question

Hi,
I created two new tablespaces (11 and 12) with 1 datafile in each of them in my primary database,
I forgot to set the parameter in standby server standby_file_management=AUTO,
the standby server auto create the tablespace 11 with datafile in D:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\UNNAMED00010,
although there is no such file 'UNNAMED00010' in D:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\.
in the v$tablespace and v$datafile, I can see that the entry had been created in control file in standby server.
Below is the listing of datafile in my standby server,
TS# name
0 G:\OFSDB\OFS4\ORADATA\OFS4\SYSTEM01.DBF
1 G:\OFSDB\OFS4\ORADATA\OFS4\UNDOTBS01.DBF
2 G:\OFSDB\OFS4\ORADATA\OFS4\SYSAUX01.DBF
4 G:\OFSDB\OFS4\ORADATA\OFS4\USERS01.DBF
6 G:\OFSDB\OFS4\ORADATA\OFS4\DATA_SE.ORA
7 G:\OFSDB\OFS4\ORADATA\OFS4\INDEX_SE
8 G:\OFSDB\OFS4\ORADATA\OFS4\FLOW_1.DBF
9 G:\OFSDB\OFS4\ORADATA\OFS4\CJHIT01.DBF
10 G:\OFSDB\OFS4\ORADATA\OFS4\DBMON_TS.DBF
11 D:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\UNNAMED00010
Anyone know how to correct this problem?
Thanks

Answer 1

You could rebuild standby from Primary. I would probably set standby_file_management=AUTO first.
If you do backups on the Primary then RMAN dup is fairly easy, and if you use the same directory structure on the standby it is really easy.
Step 1.
On the primary
alter system set log_archive_dest_state_2=defer;
Step 2
Create a temp init file for the standby
Set the following:
db_name, control_files, db_recovery_file_dest, db_recovery_file_dest_size, compatible,
db_block_size, undo_tablespace, undo_management, undo_retention
Step 3
Backup Primary
RMAN RUN {
allocate channel d1 type disk;
backup format '/u01/backups/PRIMARY/df_t%t_s%s_p%p' database;
sql 'alter system archive log current';
backup format '/u01/backups/PRIMARY/al_t%t_s%s_p%p' archivelog all;
backup current controlfile for standby format '/u01/backups/PRIMARY/sb_t%t_s%s_p%p';
release channel d1;
Step 4 Copy backup to standby
Consider any cleanup of old files on the standby now since they probably are worthless
Step 5 Move current archive
Move the current archive (todays) log backups to the target server.
A list backup may show only the ones you need.
RMAN> list backup;
Step 6 Startup the standby
SQL> startup nomount pfile='/u01/app/oracle/admin/PRIMARY/pfile/init.ora'
(With the INIT file you created in Step 2)
Start as your Primary DB NAME
Step 7 Issue Duplicate command
rman target sys/password@PRIMARY auxiliary /
RMAN> run {
allocate channel C1 device type disk;
allocate auxiliary channel C2 device type disk;
duplicate target database for standby nofilenamecheck;
When this completes
Make sure you shutdown the database and then switch the ORACLE_SID=STANDBY
Step 8 Copy init.ora from primary host
(Or if you have a good PFILE version on the standby correct and make a new spfile)
Step 9 Start redo apply
On the Primary
SQL> alter system set log_archive_dest_state_2=enable;
Start Redo apply
On the standby database, to start redo apply:
SQL>startup mount
SQL> alter database recover managed standby database disconnect from session;
Database altered.
