Database information in control file

hi, i want to know what is database information in control file(reset logs scn and timestamp)
what this information is .as the control file contains checkpoint information .i.e it also contain scn.how does this database information related to archivelog which is applied to datafile and does redo log contain scn information.
thanks in advance.

control file contains all the infromation about the database like scn, database name, database created date, datafile and location, logfile and location, max log group, and so many infromation.
But this is the common question, before post your question kindly check in the internet, if you dont get any answer then post your question here.
Cheers

Failed to load database information.Error in File BillReport {Some numbers}.rpt

Hi Team I am having problm with Crystal Report for Visual Studio 2013.
I have developed windows application with Crystal Report and Visual Studio 2010.
Now when i try to run same code in VS 2013 with Crystal report for VS 2013. i am getting following error.
Failed to load database information.
Error in File BillReport {A677B982-B8FC-4349-8BE6-9D1DA6B33521}.rpt:
Failed to load database information.
Source : "CrystalDecisions.ReportAppServer.DataSetConversion"
I have used oledb connection to fill XML dataset.
That dataset is binded to Crystal report at run time..
Here is my code.
string sqlstr = "";
                sqlstr = "select * from billMaster where billid = " + billId + " and merchantName = '"+merchantName+"' ";
cmd = new OleDbCommand(sqlstr, m1.ccon);
                if (m1.ccon.State == ConnectionState.Closed)
                    m1.ccon.Open();
                OleDbDataAdapter da = new OleDbDataAdapter(sqlstr, m1.ccon);
                BillPrint bp = new BillPrint();

<startup useLegacyV2RuntimeActivationPolicy="true">
</startup>
is the solution man.
Thanks a lot...
I tried this one also..
Try saving the DS ( bp ) to xml format and have a look at the data, it may be a data field type has changed with the new OLEDB driver in VS 2013. This may be what Dell is referring to...
Try this:
bp.WriteXml("c:\\sc.xml", XmlWriteMode.WriteSchema);
Then set the report to the xml data source:
System.Data.DataSet ds = new System.Data.DataSet();
ds.ReadXml(@"C:\App_Data\sc.xml", XmlReadMode.ReadSchema);
rpt.SetDataSource(ds);
but it didn't help..
anyway
<startup useLegacyV2RuntimeActivationPolicy="true">
</startup>
this one is solution..

Oracle control file header information

Hi,
I want information about control file header.
My requirement is,
1. Start database in backup mode so that header of the datafiles got freezed.
2. So i want to know header_information/freezed SCN no in the header of the control file. From which oracle view i can get this information?
Thanks

The informationi in controlfiles is the centralized information of whole database like db_name,dbid,logfiles & datafiles paths,SCNs,etc..So if you want the controlfile structure or its internals the following link may help you out :

Check the value for the parameter "COMPATIBLE" in the source and standby database instance parameter files.
"COMPATIBLE" should be the same.
See http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#i70517
"... ensure the COMPATIBLE initialization parameter is set to the same value on both the primary and standby databases"

RECREATE DATABASE Using CONTROL File After SUSPEND Database

Hello All,
Does someone can tell me if he does achieve recreating a database using "Backup Control File" after putting database in "suspend" mode?
The procedure looks like this :
1 - Alter DATABASE Suspend
2 - A Snapshot of the filesystem where the oracle datafile are located
3 - Copy of those files to another file systeme
4 - Startup setting a new database name
Does someone as do it successfully ?
Thanks for your answer

Carlos,
I tried to do it without putting the tablespaces in backup mode and it didn't work for me. At that time adding the backup mode wasn't a big deal for me, so I didn't investigate the problem thoroughly.
Logically thinking you sould be able to do:
1. suspend database
the SCNs recored in datafiles headers could be incosistent at this point
2. make a snapshot
3. mount the backup database
4. run recover until cancel using backup controlfile - I don't think you can avoid this step in case if you have inconsistent SCNs in the datafiles headers - you'll need to synchronize them
5. open resetlogs.
the suspend database should eliminate the possibility of inconsistent data within a block during the backup.
Just out of curiosity - why don't you want to put the tablespace in the backup mode?

Problems creating control file in RMAN duplicate database

There is so much detail involved in this operation that I don't know what might be useful, so I'll start simple. I'm attempting to clone a database on the same host using RMAN "duplicate database". I finally got all the setup done, the OS authentication hurdles hurdled, etc. and entered the command:
duplicate target database to COPYCH2M until time "to_date('March 15 2012 12:00:00', 'Mon DD YYYY HH24:MI:SS')";
The first time I got:
ORA-19504: failed to create file "/u01/app/oracle/oradata/COPYCH2M/control01.ctl"
ORA-27040: file create error, unable to create file
Linux-x86_64 Error: 2: No such file or directory
There was nothing in the Oracle instructions about manually creating the directory, but I did so, thinking that might be the problem. And it created the control files! But then I got the following:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of Duplicate Db command at 05/21/2012 15:59:25
RMAN-03015: error occurred in stored script Memory Script
RMAN-06136: ORACLE error from auxiliary database: ORA-00201: control file version 11.2.0.0.0 incompatible with ORACLE version 11.1.0.1.0
ORA-00202: control file: '/u01/app/oracle/oradata/COPYCH2M/control01.ctl'
Sounds straightforward, if frustrating, right? Apparently you can't duplicate a database that's not in the exact same version. But:
1) The backuppiece we got the control file from was from last November.
2) The version of Oracle has not been updated since that time.
How can a file created by this version be incompatible with this version? Where is it even getting 11.1?
Thanks, I'm hoping this is easy but I can post more info if needed.

>
There was nothing in the Oracle instructions about manually creating the directory, but I did so, thinking that might be the problem. And it created the control files! But then I got the following:

The database is limited as to what it can create. Since you defined where you wanted the controlfiles to go (pfile/spfile), it's up to you to make sure the directory is valid and exists. :)
>

As for your controlfiles, make sure the compatible parameter is set the same on both the source and the target unless you are using the default (11.1.0.1 for you, and you aren't)
Keep going, you'll get there. RMAN duplicate is a great feature.
Good luck.

What is the difference between data file & control file

what is the difference between data file & control file

Dear Deba s
Control file
Every Oracle Database has a control file, which is a small binary file that records the physical structure of the database. The control file includes:
The database name
Names and locations of associated datafiles and redo log files
The timestamp of the database creation
The current log sequence number
Checkpoint information
For more info look into these
[Control File Basic|http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14231/control.htm#i1006143]
Data File
You manage Data File in your Oracle database as part of Space Management. You can extend, create, drop, and alter tablespaces.
You especially need to avoid tablespace overflow, which is when a tablespace runs out of freespace in the allocated file or files. This happens when an object requires a new extent but there is either no freespace or insufficient freespace in the tablespace
For more info look into these links
[Data files |http://help.sap.com/saphelp_nw04/helpdata/en/98/5dd5890f32274aa884e45e736752a2/frameset.htm]

What is Control file ?

Hi Gurus,
Please explain me that what is Control file and what was the purpose of it in SAP Oracle DataBase.
Thanks.

Hi Kalyan
<b>What Is a Control File?</b>
Every Oracle Database has a control file, which is a small binary file that records the physical structure of the database. The control file includes:
The database name
Names and locations of associated datafiles and redo log files
The timestamp of the database creation
The current log sequence number
Checkpoint information
The control file must be available for writing by the Oracle Database server whenever the database is open. Without the control file, the database cannot be mounted and recovery is difficult.
The control file of an Oracle Database is created at the same time as the database. By default, at least one copy of the control file is created during database creation. On some operating systems the default is to create multiple copies. You should create two or more copies of the control file during database creation. You can also create control files later, if you lose control files or want to change particular settings in the control files.
<b>Guidelines for Control Files</b>
This describes guidelines you can use to manage the control files for a database, and contains the following topics:
Provide Filenames for the Control Files
Multiplex Control Files on Different Disks
Back Up Control Files
Manage the Size of Control Files
Role of Control File will remain the same even when you use Oracle with SAP. Just there will be some more entries in the file.
Refer the link below as well:
http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14231/control.htm#i1006143
Hope this should clear you doubt.

Need a help: how to recover using backup control file?

Please a help:
First computer
1. I create a database
2. put it in archive mode,
3. shutdown and made a cold backup
4. Created backup control file (alter database backup control file to trace)
5. I started up and created some archived log files.
Second Computer
1. I copied all files created in the step 3 above except the control file
2. I create all the same map directory on the 2nd computer as in the 1st computer
3. I recreate the control file from the script got in the step 4 above
4. I Copy archived log files generated at the step 5 in the local directory in the second computer
5. I set the logsource and set the autorecovery to on
6. I recover the database: RECOVER DATABASE USING BACKUP CONTROL FILE UNTIL CANCEL
Error got:
the archived log file applied do not go beyond the first one?,How could I do to applied all archived log files copied from the first computer to the second computer to have the same data?
Thank you very much

Crystal report "Failed to load database information" error after publish

I have seen similar questions, but none of the answers seem to apply to my situation.
I am upgrading an older web application to Visual Studio 2013, using the SAP Visual Studio Crystal Reports tools. Everything works great until I publish.
I have two sorts of reports: Some that export to Excel, and some that export to PDF. All work fine within Visual Studio. However, when I publish, the reports that should go to PDF give me the following error.
Failed to load database information.Error in File [Report Name] {GUID}.rpt
I have seen several posts that indicate that this could be a 32/64 bit issue. I am using a newer 64 bit SQL database, and this is an old application. I have it set to Any CPU. However, since the reports work fine in Visual Studio, I don't see how this could be the issue.
Any other ideas?
Thanks,
Geoff Callaghan

Hi Geoff
This is definitely not due to the export type. Rather it will be due to a db issue of some sort. My suspicion is that reports that work use a different type of connection that reports that fail. E.g.; the reports that work use OLE DB, those that fail use ODBC and the ODBC datasource is 32 bit, not 64 bit(?). E.g.; check the database connections between reports that work and those that do not. And remember to also check the connections in subreports (if any).

Creating a control file copy with ASM

Configuration is Oracle 10.2, RAC, and ASM (Automatic Storage Management). I would like to create a second copy of the control file.
If this wasn't ASM, I could just bring down the database, copy the control file using an operating system command, modify the pfile to reference both the original and new copy, and then restart the database.
Since this is ASM, I cannot use an operating system command to copy the control file, and RMAN "BACKUP" (which is the only way I know to make a copy of the control file) will only work if the database is up. When I "restore" the control file using RMAN and change the pfile to reference both control files I get a message like the following when attempting to start the database:
ORA-00214: control file '+ASMGROUP1/db1/controlfile/current.271.566646845'
version 2241 inconsistent with file
'+ASMGROUP1/db1/controlfile/current.268.566661765' version 2236
Soooooo, how do I make and implement a second copy of a control file using ASM.
Thanks

Hi.
This is not testet so presede with caution as it is meant as a discussion ;-)
As I see it there is no logical way to extend the instance by adding a controlfile.
The following procedure might work (has not been tested)
I think you have to make a controlfilebackup with the database closed in normal mode using RMAN.
Further you might be able to edit the pfile with create pfile from spfile and further create spfile from pfile. Extending the controlfile parameter to represent number and names of controlfile needed.
With this done, the database is closed normal with a controlfile copy presented somewhere on the filesystem.
startup mount;
restore controlfile from '<backup controlfile location>'
alter database mount;
alter database open;
Any thoughts about this procedure guys?

Database Recovery using Archive files

Dears,
Due to some issue our database get crashed.
We have saturday night offline backup and archive backup till yesterday night.
We have restored offline backup and system is Up but it is on saturday night state.
We want to apply these archive files to make the system state to current.
In restore our control file also get replace with our saturday night control file status.
We have copied our archive files in oraarch directory.
Now when using brtools I am applying archive files:
Command executing in brtools:
recover from '/oracle/<SID>/oraarch' database
it shows
unknow command beginning
No recovery required
On sqlplus also when I execute
sql>recover database;
It shows no recovery required.
When I give command:
sql>recover database using backup control file;
it ask for some {file name| AUTO | CANCEL}
I give first file name of oraarch it shows "Can not access the file".
File permissions are ok.
I give AUTO, It also then do not do anything.
Please suggest the correct method to make my system in latest current date.

Hi Shivam,
This is absolutely normal that during the restore your control files will be replaced by the old one which were backed up during database backup.
Logic is that you can not apply the redolgs which are having the timestamps older than your restored datafile's / controlfile's timestamp.
If your DB is not yet opened, you can check the status of your database using below command which will tell you, till what timestamp your data is restored or currently available.
select to_char(CHECKPOINT_TIME,'yyyy-mm-dd:hh24:mi:ss') from v$datafile where file#=1;

recover database using backup controlfile..... this command does not backup the controlfile . this will make use of old controlfile only which came along with the restore and start the recovery using this controlfile only.
Its just make use of available controlfile ..No backup will be triggered.
Please make a note that after DB restore; ..recovery is possible only in case database is not yet opened in OPEN state.

Only a cold datafile backup. No control files, redo files, archived redo

Hi everyone,
I made a stupid mistake and am in a bad condition with only a cold database backup without control files, redo files and archived redo files. My oracle database is oracle 9i. Is there any way to get my data back?
Thanks,
Yanping

Hi,
Have you a backup trace of a Control File ??
You can try perform this:
eg:
oracle@linux:/u01> cp -a /backup/*.dbf /u01/oradata/DB01
oracle@linux:~> sqlplus
