I deleted the control file using $rm control01.ctl. But i perform the back up
rman> backup incremental level 0 database;
i have no any backup
so how can i recover the my lost control file to connect with oracle instance.
The controlfiles were corrupted due to some issue. So, I had to restore the recent backed up control file and then restore the database.
The weird thing which I have noticed is that. I tried backing up Yesterday's Control file. So, I would say that the backup pieces it should pick should be from yesterday. however, the backup pieces are getting restored from last week's backup.
I have a problem with my control file [URL].........
What I did, I have a duplicate of the database with the invalid control file, let's call it DUMDB. I am using my control file and no recovery-catalog-db.
I recreated the control file. Now everything is working fine, new backups can be taken, restores can be made. I just need to restore a backup tagged with "LASTDEV". The control file for this backup is the invalid one. So I need a restore WITHOUT restoring the control file.
I did:
CODERMAN> catalog backuppiece '/u03/flash_recovery_area/DUMDB/backupset/o1_mf_nnndf_LASTDEV_75fmkllw_.bkp';
cataloged backup piece
backup piece handle=/u03/flash_recovery_area/DUMDB/backupset/o1_mf_nnndf_LASTDEV_75fmkllw_.bkp RECID=1 STAMP=761604017
CODERMAN> list backup;

I am on 11.2.0.2.0 on Linux64.
I did a hot back up like this :
--check that it is in archivelog mode
SQL> archive log list
-- the data files that will need to be backup by OS command
SQL> select sum(bytes) from dba_data_files;
SQL> select name from v$datafile;
-- note archivelog sequence before starting the hot backup (need to back the archivelog generated during the backup)
SQL> select thread#, max (sequence#) from v$log group by thread# order by thread#;
-- begin the backup
SQL> alter database begin backup;
-- use OS command to copy the datafiles
-- remember to end the backup mode
SQL> alter database end backup;
-- archive the current online redo log files
SQL> alter system archive log current;
-- REMEBER to note the MAXIMM online-redo sequence number
select thread#, max (sequence#)from v$log group by thread# order by thread#;
-- backup the control files
SQL> alter database backup controlfile to '/oradump/hbackup/O11R2/controlbk.ctl' reuse;

To what i understand one can restore a missing control file if you have multiplex it. so I did this :
ORACLE instance shut down.
SQL> startup
ORACLE instance started.
-- while it is being down, i use OS command to copy a good copy of the control file to the missing controlfile location + name.

I have installed oracle 11.2 on virtual machine and made two copy of this vm i.e vm1 and vm2...i have taken fullbackup with rman on vm1 and autobackup of control file.Now i want to restore this backup on vm2, for this i have configured channel and other setting. run following command
catalog start with '\server3database_backup
manC-3507808503-20130531-00';
"C-3507808503-20130531-00" is the name of control file autobackup.
RESTORE CONTROLFILE ;
it gives me error RMAN-06496: must use the TO clause when the database is mounted or open...then i use following command
RESTORE CONTROLFILE to 'C:oracleAdministratororadataslate';
then it gives me error RMAN-06024: no backup or copy of the control file found to restore...how to restore control file to vm2
I've got a legacy SAP system with oracle 8i on Tru64. No changes at all are made but for legal reasons we have to keep it up and running.
we currently do a full backup monthly by shutting down oracle and doing a backup of all the files to tape and that takes around 12 hours.
If I stop doing the full backup and I only backup the control file and the archived redo log files every month and I had to restore the full database years from now, would I be able to restore the database using the last full monthly backup and use the latest control file and archived redo log files?
I take hot backup of database at 10:00 am.After taking the hot backup 50 archived logs are created.Out of 50 i have backed up first 25 of them and at 5:00pm i lose complete database including control,data and the last 25 archived log files that were not backed up.So I am using latest hot backup to recover
I restore the control file backup and datafile backup taken during ho tbackup(10 am) and i issue the command
.......startup mount
>>>>>>>Recover database until cancel
!!!!!!! Apply the available 25 archive logs
then i give "cancel" since I dont have the next redo log .Now in which mode will the database open(Reset logs or no reset logs)
I want to restore control file from backup set,just as the flowing command,where location does the control file be restored to? how can i specify the location when restore control file?

View 12 Replies View RelatedI had a database on an old P4 running but the motherboard got fried. I was able to recover all the data files (.ctl and *.dbf) plus the redo logs (.log). There is no export or backup taken - I have old ones, but I need to recover the latest which only existed in the data files.
I now have Oracle installed on a new P5 machine and was wondering if it is possible to use these data files in the new database? If so, how do I go by restoring the data files?
Both the P4 and P5 where running Red Hat Linux.

Is there a way to configure connect time failover and connection timeout in the connect identifier used by DGMGRL? It does not seem to respect the parameters I supply.
This is what I used for TNSNAMES connection string:
DB=
(DESCRIPTION =
(ADDRESS_LIST =
(FAILOVER=ON)
[Code].....
When the hosts are up, if the instance is not running, I really get a quick reply from DGMGRL. However, when some host is not available, it can take quite a while to get an answer, minutes..
=
I though I could use
(TYPE=select)
(METHOD=basic)
(RETRIES=5)
#(DELAY=1) # defaults to 1 when retries is set
in the connect_data section, but this does not seem to have an effect
=
I also tried ' (CONNECT_TIMEOUT=5)' in the ADDRESS_LIST section
=
So assuming that Oracle NET services are not available on the hosts. What can I use to make 'dgmgrl' report that it can't connect to the host quickly ? Should I look into the TCP timeout parameters ?

I am having a issue, we are trying to restore our db from control files using Symantec Backup exec, but job fails giving me error go to table spaces select all table spaces and unchecked roll forward.
i am unable to find way to uncheck the table spaces. Here is the complete description.
Cause
The system catalog tablespace "syscatspace" contains all of the system catalog information for the tables. Syscatspace needs to be rolled forward first, and then the other tablespaces must be rolled forward.
Solution
Workaround:
When the restore operation is run from a tablespace level backup, perform the rollforward for the syscatspace tablespace first and then for other tablespaces.
Execute the rollforward operation as a DBA operation. The sequence of the recovery process should be as follows:
1. Select all tablespaces, uncheck the rollforward option and run the restore job.
2. Run the rollforward operation as a DBA initiated operation:
rollforward syscatspace to point in time / end of logs. e.g. db2 => rollforward database UEXIT to end of logs and complete Tablespace (SYSCATSPACE) online
3. Perform rollforward of all other tablespaces.
e.g. db2 => rollforward database UEXIT to end of logs and complete tablespace (SYSTOO LSPACE,USERSPACE1) online
Refer to IBM DB2 documentation for more information on DBA-initiated operations.
is there any way you can get the name of the file loading the table in a control file? i have a table with a column called source_file, and need to populate it during the load.

I cannot can't to the Oracle database from Delphi. The error I keep getting is:
Alias is not currently opened. [Oracle][ODBC][Ora]ORA-12154:TNS: could not resolve the connet identifier specified.
Here's what I've done:
1. Create an ODBC connection to my Oracle database
- run C:WindowsSysWOW64odbcad32.exe to open the ODBC administrator.
- Data source name: bt_user
- TNS Server Name: localhost/xe
- user bt_user
- Clicked "test connection" -- Success.
2. Open Delphi and drop a TDatabase component on my main form.
- Set the Alias Name property to "bt_user" (the alias I set up in ODBC)
- Set database name to "bt_user".
- Checked "connected".
Alternatively, I tried using the Delphi ADO components (the dbGo components).
- Drop TADOConnection component on my form.
- Select "connection string" and open the dialog.
- Click "build string".
- Select "Microsoft OLE DB Provider for ODBC Drivers" from the selection.
- In "use data source", select "bt_user" from the drop-down list (my ODBC connection from #1)
- Click "test connection".
Again the same error.
My questions are:
1. Can Delphi work with Oracle XE (Express Edition)?
2. If so, then do I need to install the "Instant Client"?
3. Will the instant client for Oracle 10g work with Oracle 10g XE?
4. Do I need to install any additional ODBC driver(s)?
5. Why was I successful in creating the ODBC connection in Windows, but it failed in Delphi?
6. Will Visual Studio.NET (C#) work with Oracle XE, and what are the steps for setting that up?
I am getting back into Oracle (from a long haul in MS only env.) and am now testing Oracle installs.I have been given a task of seeing the diff. between 12c and 10.2g...I set up 2 vms (excatly same configs) and used the same dmp file (on both env.) to restore data and settings for our jobs to run.We have some aggregated data, and cubes with DIM tables each being run on the vm machines. We run nightly jobs to rebuild our cubes.
I am supposed to see/analyze the value of 12c, and understand things might vary from company to company, but am perplexed at my result.12c is half the speed of 10.2g, both env. are the same out of the box with same dmp file and same hardware.
I am using the same dmp file, with the same jobs on each machine, with both vms having 10.2g or 12c installed out of the box as is.what default oracle settings might have changed from 10.2g to 12c that could make the exact same env. run twice as slow on the 12c?
Expectations were that out of the box with both machines running same jobs on same data (from dmp files) would have it that 10.2g would be slower than the 12c, except the 12c takes 2 times as long to run the jobs. I have reviewed every possibility as I know usually the problem is the person sitting in the chair and not the pc...but I confirmed all was identical from the one vm env. to the other, except the version of oracle out of the box.
What could be done to bring that default setting back to atleast equal time between the 2, that would give me a great starting point. Otherwise, I would have to toss this up to bloatware.
I read up a bit on the CBO, and know this might have changed in 12c.is there a way to bring it back to a backwards ealier config, so as to atleast match both env. execution plans?
I have a database "BD001" for example, inside got 90 schemes, each one has two tablespaces, see below script I use to create:

In my system all my control files get corrupted.
FYI,I have taken control file backup and DB backup also 6 hour before the control file get corrupted,then there are quite lot of DB structure change, so Now how to recover my control file with the upto time DB state , since the backup was taken for control file 6 hour before the file get corrupted, now how do I revery the DB/control file, step by step with syntax as well.
I know this question must have been asked several time. I just want to know the many ways in which we can have a DB up and running even if we do not have any backup of control file not even the trace of the same.
