  It seems that the recovery was stuck between the two.
  Please advise me how to kill the recovery session that is stuck. because I don't want to bounce the database pending.
  
  Thanks in advance.

  Dataguard and MRP, you run a script before.

  In a standby scripted, a session to RETRIEVE the DATABASE would an UNTIL clause (SEQUENCE up to THAT most likely). At the end of the recovery at this point (SEQUENCE #), he left and stop at the database.

  In addition, the script is such that when a RECOVERY session is active, another session is not authorized to start. It can loop in pending state or go out and do it again the next scheduled interval.

  Apparently your startup script is not strong enough to prevent another session of RECOVERY to start even though the first is active (or it doesn't have a good up to THAT clause and stop, exit, closing stocks)

  What you have is a custom implementation of a database of pending. Without all the details of the script, the 'blocking' between sessions (to avoid a second RECOVER start when one is already running) etc... We can't really do much to help you.
  Your scripts must be standing with status information. It should be possible for you to discover the 'other' sqlplus session which emanates a DATABASE to RECOVER, but not yet out (p. ex... How about a simple "ps - ef |") grep sql' and ' ps - ef | combination of grep ora"?)

• ORA-19846: cannot read the header of the data file of the remote site 21

  Hello

  I have a situation or I can say a scenario. It is purely for testing base. Database is on 12.1.0.1 on a Linux box using ASM (OMF).

  Standby is created on another machine with the same platform and who also uses ASM (OMF) and is in phase with the primary. Now, suppose I have create a PDB file on the primary of the SEED and it is created successfully.

  After that is a couple of log, do it again passes to the waiting, but MRP fails because of naming conventions. Agree with that! Now, on the primary, I remove the newly created PDB (coward the PDB newly created). Once again a couple of switches of newspapers which is passed on to the wait. Of course, the wait is always out of sync.

  Now, how to get back my watch in sync with the primary? I can't roll method until the required data (new PDB) file does not exist on the main site as well. I get the following error:

  RMAN > recover database service prim noredo using backupset compressed;

  RMAN-03002: failure of the command recover at the 18:55:32 08/11/2015

  ORA-19846: cannot read the header of the data file of the remote site 21

  The clues on how to I go ahead? Of course, recreating the eve is an option as its only based on test, but I don't want recreation.

  Thank you.

  I tried like below:

  1 a incremental backup of the primary of the CNS where off the eve also taken primary backup controlfile as Eve format.

  2 copy the backup of the watch parts, catalogged them on the day before.

  3 recovered Eve with noredo option - it fails here with the same error pointing to the 21 data file.

  OK, understood. Try not to get back the day before first, rather than restore the controlfile and then perform the restoration.

  Make it like:

  1. take incremental backup of primary SNA, also ensures the backup controlfile format.

  2. copy pending, get the location of the data file (names) by querying v$ datafile on the eve. Restore the controlfile ensures from the backup controlfile you took on primary and mount.

  3. Since you are using OMF, the path of primary and standby data file will be different. (/). If you require catalog data from the database files pending.

  (Reason: you restore controlfile from elementary to step 2, which takes place from the main access road). Use the details that you obtained in step 2 and catalog them.

  4. turn the database copy by RMAN. (RMAN > switch database to copy ;))

  5 Catalog backup items that you copied in step 2.

  6. recover the standby database using 'noredo' option.

  7. finally start the MRP. This should solve your problem.

  The reason I say this works is because here, you restore the controlfile to primary first, which will not have details 21, datafile, and then you are recovering. So it must succeed.

  In the previous method, you tried to first collect all the day before, and then restore the controlfile. While remedial classes, always watch seeks datafile 21 as he controlfile is not yet updated.

• On the use of the data file

  Hi all

  Last week I was simulating a crash of my database (Oracle 11.2.0.3, last group of patches) due to data files missing. So, I just removed the data file where my web application stores the data to see what's going to happen. But nothing happened, demand is rising and running and I was able to create new items in the user interface and save them. Normally, all these data are stored in oracle.

  After that I created a few articles, I bounced the database. Then I restored and retrieved the data file with RMAN. All items I created after the deletion of the data file were there.

  I would like to know, in which oracle order would write the DML commited to for recovery logs and the data file, so that I can explain the behavior of the application. I was wondering how the commited changes after deletion of the data file have been preserved even after the restoration of the data since the last backup RMAN file.

  Thanks for any input.

  Best regards

  Coby.

  every time that you agree to any transaction that the LGWR writes that transforms redo log buffer to restore the log file. When saturates redolog files then it launches checkpoint and writing each thin to the log file archive.

  DBWR writes data to the buffer cache of datafile only if it doesnot have free tampons with him.

  In your case, what could have happened is when you deleted the data file and made changes in the database. He could not write these changes to the data file and made the entery in the redo log file.

  so, after you have to bounce the database and restore the database and retrieve using the archiving log. you'd get output like media recovery complete and all the changes made to the database once you have deleted the data file, all the changes has returned to recovery.

• Defining the new path for the data files for restoring using the VALUE of NEWNAME FOR DATABASE

  So I had to rename each file as below

  $ mv 3 /fnup/hwrc/oradata/spikey/undotbs01.dbf

  I would have been better in execution of the order for each data below file

  SET NEWNAME FOR DATAFILE

  Now, I think, there is no advantage in using NEWNAME SET of DATABASE to. Only the disadvantages. I did anything wrong above?

  Martin;

  On the issue of the VALUE of NEWNAME FOR DATABASE, you must specify at least one of the first three of the following substitution variables to avoid collisions of names: %b f % U. see semantic entry for TO 'filename' for a description of the possible substitution variables.

  You use %f

  %b
  
  Specifies the filename without the fully qualified directory path. For example, the datafile name /oradata/prod/financial.dbf is transformed to financial.dbf. This variable enables you to preserve the names of the datafiles while you move them to different directory. During backup, it can be used for the creation of image copies. The variable cannot be used for OMF datafiles or backup sets.
  
  %f
  
  Specifies the absolute file number of the datafile for which the new name is generated. For example, if datafile 2 is duplicated, then %f generates the value 2.
  
  %U
  
  Specifies a system-generated unique filename. The name is in the following format: data-D-%d_id-%I_TS-%N_FNO-%f. The %d variable specifies the database name. For example, a possible name might be data-D-prod_id-22398754_TS-users_FNO-7.

• Incomplete data file recovery

  Hello
  
  I use oracle database 10g (10.2.0.10) in RHEL5. I want to make a point in time recovery a backup data file. Through RMAN, I published the following command
  
  RMAN > run {}
  2 > sql ' alter session set nls_date_format = "dd-mon-yyyy hh24:mi:ss";
  3 > set until that time August 21, 2011 13:04 ';
  4 > restore datafile 4;
  5 > recover datafile 4;
  6 > alter database open resetlogs ;}
  
  But RMAN made a full recovery. Yet once again, I deleted the data file and restore the backup data file. Now, I wrote the following at the SQL prompt
  
  SQL > alter session set nls_date_format = 'dd-mon-yyyy hh24:mi:ss ";
  Modified session.
  SQL > recover datafile ' / u01/app/oracle/oradata/ORATESTDB/datafile/o1_mf_users_751h7fmh_.dbf' until August 21, 2011 13:04 ';
  ORA-00274: illegal until recovery option
  
  It displays the above error. But I am able to perform incomplete recovery of the complete database using RMAN same as above.
  
  Done datafile point-in-time recovery is not possible? or is there something wrong in my approach?
  
  Kind regards
  
  007

  A data file can be recovered to a point in time which is incosistent with the rest of the database.
  (why? Data integrity! A table with several extensions that can cover several data files. You can't have some scopes with data from 12:05 and other extensions into another file of data retrieved using data from 10:05! Even if it's a single datafile tablespace, you will violate referential integrity (whether or not they are applied) If, say, the SALES table has entries until 12:05, but the SALES_LINES table has entries until 10:05!)

  You can make a Tablespace recovery time by using an auxiliary Instance and then copy the tablespace back. You must maintain integrity.

  To be honest, I don't really see what you have done in the op, so I can't really comment on. I see you have an export of the TTS, but that's all.

  If you have followed all the list I mentioned (you did write the TTS reading?), then you can try to save the file with RMAN, but I suspect that it does not work. Do you get the error even if you move the shared location (/ donneesimporter) to a local directory on the target area? Maybe he doesn't like the fact that it's a NFS mount (or whatever the proportion is).

  Or maybe it's because you going to 10.2.0.4 10.2.0.5. I have always had the same group of patches and updated once I had plugged the tablespaces on the target database.

• ID of file of the data file created using CREATE the DATA file

  Version: 10 gr 2
  
  I lost a test data file that was created in the morning. No available backup. I have all logs archived.
  
  Question1.
  Here are the steps to recreate. Right?

  1. alter tablespace <tablespace_name> offline immediate;  --- should this be offline drop?
  2. alter database create datafile '/u03/oradata/dbtst/CLM01.dbf';
  3. recover tablespace <tablespace_name>;
  4. alter tablespace <tablespace_name> online;

  Question2.
  The newly created file will retain the ID file from the original file that was lost?

  Since you're on 10g, you have not manually create the data file. Check recovery of a Datafile without backup lost: example for more details.

  The identifier must remain the same.

• A SCN for the entire database and the different SNA for the data files?

  DB Version: 11 g
  
  I always thought that there is a unique SCN for the database as a whole.
  A quote from the link below as
  When a control point is completed, Oracle stores the RCS individually in the control for each data file file
  http://www.dbapool.com/articles/1029200701.html
  
  
  What does that mean? There is a SNA for the entire database, and there are individual SCN for each data files?

  Well, unfortunately, the article says more bad than good things. Or if I can't call them wrong, they are rather confusing and rather than clear things for the reader, its making them appear to look more confused.

  First things, YVERT is used for read consistency (CR) mechanism and the backbone of the notion of Multiversioning. The control point is the mechanism to help that recovery is decided. Contrary to what said article, not any kind of checkpoints update both the data file and the control file, and also, there is not a type of them as well. In addition, the article says that the LAST_CHECKPOOINT is set to NULL, while its actually set to the infinity since it is not possible to detect the moment when the database is opened, that the last issue of control over the file would be. In the case of complete control point, this number is saved and is also associated with the toa Controlfile own database leader at the next startup. If this is not the case, there is an inconsistency in the stop_checkpoint of the data file and the stop_checkpoint reocrded in the control file, leading to a recovery of the instance.

  There are several types of control points. Similarly, there are several types of SNA as well. Without going into the details of these, IMO, the article simply means that when the control point write over a file passes, oracle updates the file checkpoint on it and this is recorded in the Controlifle. as well.

  RMAN-03002: failure of Duplicate Db command at 10/10/2009 18:00:39
  RMAN-03015: error occurred in stored script Memory Script
  RMAN-06026: some targets not found - aborting restore
  RMAN-06100: no channel to restore a backup or copy of datafile 43

  Redo log which was Pond at the time of the creation of 43 of the data file is also available in the backups. It seems that RMAN cannot use the log information archived redo to restore the content of the data file 43. I guess that because failure is already reported in the RESTORATION and not in the RECOVERY phase, so again the archived logs are not available yet. I get the same message even if I do another backup of the data file 43 (so a backup that is not in the same backupset as the backup to all the other data files).
  The script, the command duplicate product, I guess that RMAN reads the contents of the source database controlfile and trying to get a backup that contains all the data files to restore the database Assistant - if such a backup is not found, it fails.
  
  
  Of course, if I try to perform a restore/recovery of the source database, it works without problem:
  

  RMAN> restore database;
  
  Starting restore at 13.10.09
  using target database control file instead of recovery catalog
  allocated channel: ORA_DISK_1
  channel ORA_DISK_1: sid=156 devtype=DISK
  
  creating datafile fno=43 name=F:\ORA10\ORADATA\SOVDEV\SOMEDATAFILE01.DBF
  channel ORA_DISK_1: starting datafile backupset restore
  channel ORA_DISK_1: specifying datafile(s) to restore from backup set
  restoring datafile 00001 to F:\ORA10\ORADATA\SOVDEV\SYSTEM01.DBF
  .....

  The 43 data file is re-created and then redo is applied to the course.
  
  So, does anyone know if the duplicate database can use archived redo logs to recreate the contents of a data file, as does a normal restore/recovery? If this is the case, then it is necessary to perform a full backup before each duplicated if a data file has been added after such a backup database.
  
  Thanks in advance for any answers.
  
  Kind regards

  Hi swear,.

  I got exactly the same problem during replication.
  Because we backup archive logs every 6 hours with rman, I added an additional block of running this script.
  run
  {
  backup incremental level 0
  format "% d_ % s_ %%t p_ bk_ '.
  filesperset 4
  database not saved;
  }

  (I also hit a bug in the catalogue which was resolved by patching up the dbs catalog 11.1.0.6, 11.1.0.7 for.)

  This will restrict the data not making file not part of any backup rman 6 hours while jumping for which there is already a backup of data files.

  Kind regards

• Generate the analog waveform based on the data file

  I want to create an analog voltage output that follows I have a data file (excel, csv, text (which is easy)).  The data file creates a waveform with equal time between steps (dT =.0034 sec).  After the output through all the data points, I want it repeat indefinitely.

  What is the best way to create the waveform of a data file?

  To create a type of waveform data, calculate the dt by subtracting two values in column 1 and get the array of Y from column 2. If you save the file as a comma separated or tab text file, you can then use the spreadsheet file read. After obtaining a 2D array, you would use the index table and the subset of table functions.

  Assuming you use a capture card data OR for the output signal, you can pass a type of waveform data to a writing DAQmx and set for the generation of types.

• Open the data file Outlook - access denied

  I have an Outlook data file created and used when I was running Outlook 2003 on Windows XP - Pro. I have a new computer with Windows 7 Home Premium. I'm still on Outlook 2003. When I try to open the data file, I get - file access is denied. You don't have permission to access the file C:\Users\Valued Customer\Outlook_xxx.pstr

  I am logged in as administrator.
  The permissions for all folders in the path and the file itself grant full control.

  I changed the owner to my new login name.
