Server Administration :: RMAN Restore Failure All Datafiles
Jul 1, 2013
I am facing an issue while rebuilding a DR (Physical Standby) site using RMAN.Rman is failing to restore all the datafiles to the stanby site.
There are 403 datafiles that should be restored among which after restoring 50-60 datafiles the channel is abruptly getting terminated.Please note this exercise is not new I have done this many times (once a year after a DR testing) and the same script is being used.The rcv file is as follows
/u03/oracle/admin/mpr/scripts/dataguard/configure_dr.rcv
connect auxiliary sys/XXXX@YYY
run {
duplicate target database for standby nofilenamecheck dorecover;
}
exit
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET;
configure_dr.rcv: END
[code]....
The trace file says "krso_proc_add: Detected dead process 13828326; subsuming V$MANAGED_STANDBY slot
INFO: krsr_rfs_atc: RFS processes are temporarily disallowed"
I have also started RMAN debug tracing and the trace is also scanned as it is huge.I have seen the following in the trace error 3015 signalled during compilation..I do not find any specific oracle error to check on .
The only change that happened is that the Primary production server has been moved to a new datacentre and after its move all the connections seems to be working fine.

Due to improper documentations of a certain project, I need to drop a DEFAULT tablespace of a newly created instance including it's associated datafiles by using this command:
"DROP TABLESPACE <tablespace name> INCLUDING CONTENTS AND DATAFILES;"
The default tablespace name is QWER (qwer01.dbf) and I added 2 datafiles in it, re: OPD_SML01.dbf & EXYT_SML01.dbf.
Do I have to do it online or offline?

What is best practice to change small disk D:? I am beginner with Oracle. 10g on W2008. 5 datafiles (all indexes,second data file, 2 undotabs)*.dbf (34;30;1;34;12 GB) is on D:. Part of tablespaces (1 data, 1 undo)has files on c:.
I.
1.Shutdown 2008 server.
2.Copy D: image with GHOST to USB, network.
3.Connect new D, create RAID.
4.Restore image to D.
5.Start 2008 server.
II.
1.Stop application.
2.CONNECT AS SYSDBA
3.SHUTDOWN NORMAL or (IMMEDIATE)?
4.Copy files *.dbf at OS level from d: to ... USB disk, network.
5.Shutdown 2008 server.
6.Change disks, create RAID in BIOS.
7.Start W2008.
Is Oracle at this moment in SHUTDOWN mode?
8.Copy back *.dbf to new D: (with directory structure).
9.STARTUP Oracle.

i encoutered lately on such statement:
Table D-7 shows a hierarchical file mapping of a sample OFA-compliant installation with two Oracle home directories and two databases. The database files are distributed across three mount points, /u02, /u03, and /u04. URL....
why three mount points (/u02, /u03, and /u04) for datafiles? don' understant this. isn't it better to store all datafiles in one mountpoint?

Can we restore a database if we have only the datafiles available? The database has been dropped but we have just the datafiles with NO system, sysaux,users and undo datafiles that were saved after taking the database offline and then dropping the database. I know this is strange but if possible, I want to see if we can retrieve some of the data from those datafiles to another database. BTW, There is no backup available for this database except the dbf files on OS.

I have checked the space of my tablespaces/datafiles in my database. I have 8 GB space left in my database server. I cant add more hard-disk as there is no slot left. We r planning to buy a new server with latest config.
My question is, how can we know upto what size our database can increase and when a datafile need to be added in advance. Sometimes even though datafiles have space left,it shows errors abt extents cannot be extended. We have coalesce the tablespaces and added a new datafile.

would want to check which tables located in which datafiles.
Tried with this command:
select B.FILE_NAME from dba_segments a, dba_data_files b
where a.header_file=b.file_ID and segment_name='TABLE_NAME'
Seems like it only shows 1 datafile. Some tables are large and i suppose it's resided in more than 1 datafile.

We have lost some datafiles and some archivelogs. We have backup of whole database taken on Dec 20 and archivelogs until Dec 23.So we dont have 1 day worth of archivelogs which can lead to incomplete recovery.
Now question is do we need to restore all datafiles or only lost datafiles for incomplete recovery since we dont have all archivelogs ? lost datafiles belong to different tablespaces.
Datafiles which are still intact are with current SCN and we restore lost datafiles only and recover unitl our last available archivelog it will have different SCN. Will we be able to open database or we need to resotre whole database for this scenario?

I have two Solaris 5.11 x86 64 bit servers. I need to be able to copy the backup files to a temp location on the 2nd server and restore that server so it is a test version of the first server. There is no RMAN catalog, I simply want to backup on A move to B restore from files copied to b.
On the first server installed Oracle Enterprise 11.2.0.3. sid = orcl. i created one schema with a new table space added a table and inserted 500,000 rows.
i set the db to archivelog=on, set configure controlfile autobackup on
i then did RMAN backup as backupset database spfile;
on the second server, i installed Oracle Enterprise 11.2.03, sid=orcl exactly like i did on the first server.i scp'd all of the files created by the backup to one location on the test server. i renamed spfileorcl.ora in dbs to somethinge else. startup nomount, exit and go to rman and run this:
DUPLICATE DATABASE TO 'orcl' SPFILE BACKUP LOCATION '/tmp/backups' NOFILENAMECHECK;
this runs for a while and looks like it works but eventually fails with :
RMAN-05541: no archived logs found in target database
subsequent attempts to 'startup' the database receive the error ORA-19838: Cannot use this control file to open database.
This is very frustrating. I have gone over all of the manuals, documentation and more but there is no 'step by step' process that i can find that is current with my version of Oracle that documents the steps necessary to simply backup a db, move it to a test server to a disk and then restore that test server as a copy of the first server.

I'm getting the error messaage:
Database Connection failure. Reason: java.sql.SQLException: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist SVR4 Error: 2: No such file or directory
I'm not an Oracle expert, but I have research a little and seems that the SID could be wrong or that the DB is down, in fact I have already checked trhe server but everything seems normal to me.

I am trying to restore a backup from a live server to a dev server. Have moved nackup sets. Created a windows service to match the old sid on live system. copied the pfile from live and changed the locations of the folders to suit dev. set oracle_sid to the new sid(as created to match live)
connected to rman
startup nomount
set dbid to the live number
restore controlfile
alter database mount
catalog'd all the backupsets
[code]....
but it fails when it tries the restore .. see below ..The path it is showing is the old path from the live server, so it appears to eb ignoring my set newname statements even though they succeeded earlier - should be restoring them to d:oracleoradatasun43dev ? Does the whole thing have to be put inside one run block or can I put bits in one run block and other bits outside of it etc?
RMAN> restore database;
Starting restore at 14-FEB-12
using channel ORA_DISK_1
using channel ORA_DISK_2
channel ORA_DISK_1: starting datafile backupset restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set

These are the commands i had issued :-
1. startup nomount
2. create SPFILE from PFILE ;
Then i got an error :-
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file 'C:ORACLEORA92DATABASEINITORCL.ORA'
Ever since this happened i am unable to connect to ORACLE under any schema !
I get the following error : -

I started restoring and testing all the backups. So far I did good and I wanted to restore and test in different host. I couldn't find any online documentation regarding restore full back up in a new different server (With same OS and same version of Oracle) without RMAN catalog database.

I'm testing out various RMAN restore/recovery scenarios for 10g R1. Took a full level-0 backup of one of our larger databases (16 tb) and I'm trying to restore the whole thing on another server. While the backup was running (for about a day & a half), a few datafiles were added. The backup completed fine, including "backup current controlfile;". Now my restore is failing with "RMAN-06023: no backup or copy of datafile xxxx found to restore", with reference to the 4 files that were added while the backup was in progress.
I guess if the datafiles were added after the backup had finished, we'd be fine because they'd be created during recovery with our archive logs (we have all of those).
I found some suggestions for first doing a "restore controlfile;" -- did that and it worked fine -- then mounting the database and creating the datafiles manually. I added that to my RMAN restore script and tried it, like so:
run {
allocate channel d4 type disk format '/BK01/dbX/stream1/df_%t_s%s_s%p' ;
sql "alter database create datafile ''/uXX/oradata/dbX/datafile_58.dbf''";
restore database ;
}
The datafiles were created successfully, and the restore began .. but then it failed with this:
creating datafile fno=4216 name=/uXX/oradata/dbX/datafile_58.dbf
...
RMAN-03002: failure of restore command at 06/20/2013 17:27:28
ORA-01119: error in creating database file '/uXX/oradata/dbX/datafile_58.dbf
ORA-27038: created file already exists
So RMAN seems to be telling me that if these 4 datafiles don't exist in the backupset, then RMAN won't automatically create them. But if I manually create them first, then RMAN will try to restore them and complain that they already exist. And for that matter, I would have expected that RMAN would be smart enough to detect that those 4 files were added while the backup was active, and just include them in the backup. Maybe there's something I needed to do to tell RMAN to do that?
This is just a test, so of course I can redo the backup from scratch and try again, but we have some pretty large databases which cannot be shut down for cold backups, so it's entirely possible this scenario could show up in a real disaster recovery. RMAN does such a good job of managing things.

I create a test database which is duplicate of my production server and after every 15 or 20 days I need to synchronize test db with production db.So I clone it and it takes about a day.I have to remove all datafiles from test and move from production to there on test server and I applied restore and recover.So it is very time consuming process.
I want to know is there any process which makes my work less like I just need to apply all rest of the logs which are new after synchronize last time from production server that need restore and recover.

We are using Oracle 10g R2 in Windows Server 2003. I'm trying to restore a database in a new server, using RMAN backups.
Our external consultant configured RMAN scripts for full and incremental backups but never tested them . Since he just doesn't show up, I'm forced to tested them, restoring the whole database in a new server.
My instance is named MTDPROD, and I will create all from scratch.
At current server, RMAN files are generated in:
//192.168.1.149/g$/XXXSRV4-ArcLogs/MTDPROD/RMAN
At new server, I run all these commands:
C:>oradim -new -sid MTDPROD -intpwd mtdprod
Instance created
-- I created the relevant folder hierarchy under <ORACLE_BASE>
directory
-- Then, I created the relevant directories for Oracle Database, as
follows:
--a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>
[code]....
By instance, I see a lot of this kind of files:
- FULL_MTDPROD_20110529_386_1.BAK
- INCR_MTDPROD_20110621_480_7.BAK
And only see these two files:
- C-2169285856-20110527-03
- C-2169285856-20110527-04
It seems that this C-2169285856-.... files only were on 27/05/2011 and then no more. However, the FULL_... and INCR_.. files are generated every day. The FULL is generated at the end of each month and INCR is generated every day.
This is the backfull.sql:
run {
allocate channel c1 type disk maxpiecesize=4G;
CROSSCHECK archivelog all;
backup
incremental level 0
format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANFULL_
[code]....
This is the backincr.sql:
run {
allocate channel c1 type disk maxpiecesize=4G;
CROSSCHECK archivelog all;
backup
incremental level 1 cumulative
format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANINCR_
%d_%T_%s_%p.bak'
