  Dear all,

  Solution:

  Location of the data file is not correct that we are mentioned in the file (init.ora) settings.

  Change the location of data file settings.

  Test the issue again.

• Backup of the file pfile with RMAN

  Dear all,
  
  How can we save pfile with RMAN? Please don't tell using this SQL > create spfile from pfile; then RMAN > backup spfile;
  
  Can we directly files pfile and password backup with RMAN?
  
  Thank you

  RMAN backup impossible pfile but only spfile. RMAN cannot backup password files. See http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup001.htm#sthref280

• sudden lack of plateau systems & under points icon passed now, even if the program is still daily backups

  The backup icon is suddenly missing from the system tray, but he always does daily backups as expected.  He used to have a daily splash screen when opening to the top of my pc and appear in the startup.

  Thank you

  Lydia

  Hi Lydia,.

  Thanks for posting the question in the Microsoft Community!

  The backup icon is missing from the system tray and you would not get the backup to the starting screen.

  To help you better, we need more information.

  You use any third-party backup program?

  I suggest you to check if the option for the backup program is disabled in the list of startup items.

  To do:

  a. Click Start, type msconfig and press enter

  b. now click on the Startup tab

  now see if the option for the backup program is enabled.

  You can also perform a virus scan.

  Visit the site:

  Microsoft safety scanner

  http://www.Microsoft.com/security/scanner/en-us/default.aspx

  Note: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

  I hope this helps. If you need assistance or if you have problems of Windows in the future, let us know and we would be happy to help you.

   

   

   

   

   

• Problem with the archive log when you use RMAN for backup and restore (11g 2)

  Hello world
  Please help me solve this problem.
  I'm just beginner in Oracle Database (11 g 2). Today, I had a problem, I tried to back up and restore my db by RMAN. I delete all the files in /u01/app/oracle/oradata/orcl / * , then I restore them easily, but the point is I have a table, I can restore Hungarian, but cannot restore anything ranks in it (something wrong with step restore database). I'll tell the detail below.
  -First, I create a 'Day' with command table create table hr.day (varchar (20)) day. Then I backup complete by this:
  run{
allocate channel bkp device type DISK FORMAT '/u01/backup/DB_FULL_%d_%T_s%s_p%p' ;
backup as compressed backupset incremental level 0 tag 'DB_FULL' database include current controlfile;
backup as compressed backupset tag 'ARCL_BKP_FULL' archivelog all delete input;
crosscheck archivelog all;
crosscheck backup;
delete noprompt obsolete;
release channel bkp;
}
  

  
  D ' other hand, I have insert 'Monday' to table. then do an incremental backup by this:

  run{
allocate channel bkp device type DISK FORMAT '/u01/backup/DB_INC_%d_%T_s%s_p%p' ;
backup as compressed backupset incremental level 1 tag 'DB_INC' database include current controlfile;
backup as compressed backupset tag 'ARCL_BKP_INC' archivelog all delete input;
crosscheck archivelog all;
crosscheck backup;
delete noprompt obsolete;
release channel bkp;
}

  Repeat 7 times (Monday-> Saturday). And I got these files:

  [oracle@rac ~]$ ls -l /u01/backup/

If i ignore it and open the database, just my table in full backup come back but rows was not restored. I'm sure the problem is my archive log backup but i don't know how to solve it. Plz help me.

  Sorry for a long post.


  > 1 and from the 1205841 SNA sequence

  The SCN that indicates Oracle is above the range of SNA that you have in the ArchiveLog backups for sequence 1 to 15 (15 sequence ends at 1205840).

  The message

  channel ORA_DISK_1: restoring archives Journal

  Archives journal thread = 1 sequence = 15

  channel ORA_DISK_1: backup/u01/backup/DB_INC_ORCL_20160120_s117_p1 piece reading

  channel ORA_DISK_1: piece handle = / u01/backup/DB_INC_ORCL_20160120_s117_p1 tag = ARCL_BKP_INC

  indicates that he has restored the sequence up to 15

  You can check the log file alert database instance for messages on the fact of recovery.

  He is now asking sequence #1 it seems you did a RESETLOGS after sequence #15.

  Note: If you have NOT issued a COMMIT after the line is INSERTED in the table 'Day', the recovery of the database will have no * transactions * to retrieve.  An uncomitted transaction is cancelled.

• Oracle 12 c with RMAN database backup

  Hi All-

  I started back to the top of one of my PDB using utility RMAN following the instructions on the link below.

  Thank you

  Just a wild guess

  You do not use this script in a command as Administrator window

  Therefore, you won't be able to create any service.

  I also have a question: your only troubleshooting activity consisted of hitting CTRL + C and CTRL-V, is not it?

  It's so boring to most of the people here do not even TRY to solve their own problems.

• RMAN bypass backup can be taken from question?

  Hi all

  pretty simple question (I hope that ):

  I use the suite at the moment for example:

  run
  {
  Backup CONFIGURATION DEVICE TYPE DISK PARALLELISM 2 to compressed backupset;
  TIME 01:00 PARTIAL minimize THE time data BACKUP FILESPERSET 1;
  }

  But I was wondering if there is some way to this running as a backup script planned to restart backup, if it does not (due to problems of space file etc.)

  run
  {

  Configure the disk channel CH1 device type format ' / alternate/path/for_backup/%d_DB_%M%D%Y_%p_%s_%U';
  Configure the disk channel CH2 device type format ' / alternate/path/for_backup/%d_DB_%M%D%Y_%p_%s_%U';

  
  TIME 01:00 PARTIAL minimize THE time of BACKUP data NOT BACKED UP SINCE TIME ' SYSDATE - 1' fileperset 1;    < < < I know it won't work like that but y at - it another way to accomplish this? (work around to restart the backup time and the option to reduce time?)
  

  
  

  cleaning etc release channels

  }

  PS: question side bonus points

  who can tell me more about the loss of speed MB/S compared to the rate of compression: low/medium/high?

  I hope that there are some brilliant minds out there willing to help!

  Thanks in advance.

  
  
  

  The themes you mention seem to be covered in the Advanced documentation of RMAN:

  http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmbckad.htm#BRADV89540

  I don't know if anyone can really give you an opinion about which compression will have the best size vs time full report. But the next test by using a simple vanilla ORCL database shows the result of the compression of 'low '. It was done on sub Oracle 11 GR 2 one running a VirtualBox VM. As you can see there is a reduction of the large size of the backupset, which however has taken so long to complete as to the 'no' compression.

  Why did you write that I know that it won't work like that? According to the example below, I don't see the problem. As you can see on the 2nd run of the backup command, it ignores the data files that he has previously treated.

• RAC RAC CLONE OF RMAN cold backup

  Hi all
  
  I need your help in my Oracle RAC 11.2.0.2 to remote host environment cloning. Here's the disc structure
  
  DGVOT (disc ASM holding OCR and voting disk group)
  DGDATA (disk group ASM containing data files)
  DGFRA (disk group ASM files for fast recovery)
  
  Remote host is on a different location so cannot use duplicate RMAN with auxiliary channel.
  Have the luxury of downtime so I wanted to take coherent RMAN (Cold Backup)
  
  SAME structure of the disc is available on remote hosts.
  
  11.2.0.2 CLusterware (IG) over the oracle binaries are already installed.
  
  Can any body tell me the steps to
  (1) how to take cold backup on the disk so that I can tar and copy to the remote host
  (2) clone of the database on the remote host
  (3) how do I add the listener for the database and other resources of this databasee clusterware.
  
  in fact, it's my first clone CARS, so I'm well aware of the steps in detail.
  
  
  I went though a lot of notes metalink but nobody fits my needs. your tips will help me a lot
  
  Kind regards

  Hello

  (1) how to take cold backup on disk so that I can tar and copy to the remote host.

  Use Rman cold backup

  At the stage of the mountain run
  RMAN > backup database archivelog format '%U /dbp ";
  RMAN > backup controlfile current format "%U /ctl";

  Copy these to the remote host backup sets

  (2) clone of the database on the remote host

  Create groups of similar ASM disk as source
  create pfile/spifile, starting in nomount mode instance
  backup set from catalog

  RMAN > catalogue start with "";

  Restore controlfile

  RMAN > restore controlfile;

  RMAN > restore database;

  RMAN > restore database;

  On the success of the recovery

  RMAN > sql 'alter database open;

  (3) how do I add the listener for the database and other resources of this databasee clusterware.

  Srvctl user to add resources

  Use: srvctl

• ORA-00245: backup of control file failed; target is likely on a local file sys

  Hello
  
  our CARS (Linux 11.2.0.3.0) is relatively new and we are still on the acquisition of experiences with this system...
  
  At the start of the backup with RMAN, we get the following error:
  
  From control file and SPFILE Autobackup 4 July 12
  RMAN-00571: ===========================================================
  RMAN-00569: = ERROR MESSAGE STACK FOLLOWS =.
  RMAN-00571: ===========================================================
  RMAN-03009: failure of command of file control and SPFILE Autobackup on channel ORA_DISK_1 at 04/07/2012 16:41:48
  ORA-00245: backup of control file failed; target is likely on a local file system
  
  The reason for the error is clear ORA-00245 - in a CCR environment, the snapshot Controlfile location must be on a shared location.
  
  When running the RMAN command "show all" on each node, we get
  CONFIGURE SNAPSHOT CONTROLFILE NAME TO ' / u01/app/oracle/product/11.2.0.3/db/dbs/snapcf_PROD021.f'; # by default
  for the #1 node
  and
  CONFIGURE SNAPSHOT CONTROLFILE NAME TO ' / u01/app/oracle/product/11.2.0.3/db/dbs/snapcf_PROD022.f'; # by default
  for the #2 node
  
  When using a shared location for the snapshot Controlfile make us still need 2 different names for this configuration file?
  
  CONFIGURE SNAPSHOT CONTROLFILE NAME to ' / < shared location > / snapcf_PROD021.f'; # by default
  for the #1 node and
  CONFIGURE SNAPSHOT CONTROLFILE NAME to ' / < shared location > / snapcf_PROD022.f'; # by default
  for the #2 node
  
  Or should set us up as a single snapshot Controlfile?
  
  RMAN installation for "CONFIGURE SNAPSHOT CONTROLFILE NAME TO... "must be changed on both nodes - correct?
  
  I hope my question is clear enough--any help will be appreciated.

  The controlfile is shared on the RAC database and having the backup of any node to shared mount point would meet the requirement.

  Configure snapshot controlfile name to ' /snapcf_PROD0.f';

• Roll forward standby with RMAN incremental backup when used DG broker

  Hello
  
  I'm about to use the process defined in the note: steps to roll forward a database ensures the RMAN incremental backup using during primaries and Eve are in the file [836986.1 ID] ASM system. I'm on 11.1.0.7.
  
  However, it does not mention the DataGuard broker.
  Did someone played this process when you use the broker.
  The broker he manages properly?
  Does it matter if the broker is upwards or downwards during the physical recovery of standby or replacement of control file?
  Should the broker configuration be re-created?
  
  Thank you.

  Hello

  I'm about to use the process defined in the note: steps to roll forward a database ensures the RMAN incremental backup using during primaries and Eve are in the file [836986.1 ID] ASM system. I'm on 11.1.0.7.

  However, it does not mention the DataGuard broker.
  Did someone played this process when you use the broker.

  Thank you.

  (1) disable the broker
  (2) perform the Roll forard SNA.
  (3) select the broker

• RMAN full backup - size SPFile Total 0.00 K

  Hello, I do some tests and I need help to understand if there is something wrong in what I'm trying to do (a full backup with RMAN, DB is 11 GR 2).
  
  If I perform a simple full DB Backup, all past file and it completes successfully. No errors.
  
  Controlfile Autobackup is enabled, so I expect to find the control file and SPFile included in the backup, too.
  
  But if I go to Console 'EM-> availability-> backup reports
  
  It is reported the following:

  Looks SPFile size on backup is '0' and not what I was expecting (SPFile is actually being used and it is not empty).
  
  Should what kind of verification I do to see if everything is OK? Maybe a non-destructive.
  
  Thank you very much!

  Hello R,

  (1) the SPFile will be restored in a custom location / name of my choice ("spfile_restore.ora")
  which may be different from the ACTIVE SPFile

  I would say that must be different from the current spfile...

  (2) the SPFile ACTIVE will always be in place and will always be that "in use" even after restoring

  Correct the restored spfile will not be part of any oracle process.
  Kind regards

• What is the role of the archived in an incremental backup redo log files?

  I want to know, to which RMAN reads what block of data is changed after the last incremental backup.
  and what is the role of the archived in an incremental backup redo log files?
  
  Please guide.

  Hello

  First Querstion response->
  Each block of data in a data file contains a system change number (SCN), which is the SCN of the last change to the block. During an incremental backup, RMAN reads the RCS of each block of data in the input file and compares at the checkpoint SCN of the incremental backup from parent. If the RCS in the block of input data is greater than or equal to checkpoint SCN of the parent, then RMAN copies the block.

  2 - the archived redolog files are required for the restoration of the online of rman incremental backup in a consistent state.

  Thank you & best regards

• RMAN-06056 and the data file does not exist

  Hello
  
  I'm working on Oracle 9i Database (9.2.0.8.0) on AIX 5.2 and we try to run a full backup of RMAN, but it seems to be failing with an error as follows;

  Concerning

  Run

  LIST OF BACKUP OF THE FILE 23

  to see if you have previous backups. If you have a backup of the data file, you can then
  Put the offline data file
  RESTORE the data file
  RECOVER the data file.

  If you want to 'ignore' this test taking it Offline datafile
  ALTER DATABASE DATAFILE OFFLINE 23

  then use "SKIP OFFLINE" in your RMAN BACKUP DATABASE command.

• RMAN information - backup of the operating system

  Hello
  I took a manual backup of a data file by using operating systems. How RMAN know about this?
  
  Thank you
  Mason.

  As Aman has mentioned, you must use the command CATALOGUE make RMAN know
  Suppose you took cold backup of the file users01.dbf data and you want to catalog them in the RMAN recovery catalog. See the example below:

  RMAN> catalog datafilecopy 'c:\users01.dbf';
  
  using target database control file instead of recovery catalog
  cataloged datafile copy
  datafile copy filename=C:\USERS01.DBF recid=1 stamp=695238977
  
  RMAN> list copy;
  
  using target database control file instead of recovery catalog
  specification does not match any archive log in the recovery catalog
