• Cloning time-consuming RMAN backup & hot

  Dear administrators,
  
  We do both RMAN & Hot backup cloning enemy that takes more time to restore the TEST instance data files. SCP taking too long to copy the server target due to its volume of data (1.5 to) and mounting of the drive of RMAN backups on test server and restore this drive taking more than 8 hours.
  
  I heard that some companies are using a device to change the copy backup hot high volume of source dest faster for clone instance easily with in a few minutes. What is the name of device to take copies of source hot backup and restore to the server target.
  
  Test server specifications
  Processor cores 8 with 32 GB of memory.
  
  Thank you
  S/N

  We have about 2.5 TB of data. It takes about 10 hours to synchronize the data.
  But everything depends on the EMC technology.
  in my previous company, synchronization takes about 1 hour to 900G of data.

• recover the database by using the RMAN backup archivelogs

  Hello
  
  I tried to find the resolution of this problem in google a lot but couldn't find something useful.
  
  Location:
  
  We try to clone the dev environment of production that are completely on different servers and do not share a common mount point.
  Backup RMAN of PROD with RMAN as well as arch newspapers are kept in this mount point.
  We took control of backup files of PROD restored in DEV fired restore with recovery until a when not.
  Turns out that the sequence was not saved in right backupsets there if recovery has not requested more arch newspapers that are present in the PROD.
  Archs are stored in ASM and only way out is to take of RMAN backup of them.
  We control the file as a repository for RMAN.
  
  my questions are
  
  1. surely, I need to take backup of the control file after I take the log arch by RMAN backup and restore this file command in the DEV of so that when I start RMAN recovery in DEV, database will be able to find the backupset with arch newspapers. But the new restore a control file will delete the data files restored information?
  
  2. If we did not have a point of common Assembly and then after sending the backup destination elements how the database would be the locations of the game copied to the new location of the control file that is restored from the backup source?
  
  Suppose that in the source backups are stored in/backup/rman
  in destination copy us in/backup/clone
  in the PROD control file, their locations are saved in/backup/rman
  so if I restore this command file in custom DEV it find the elements of backup in/backup/rman?
  is it possible to save a backup of outside item in the control of a database file?
  
  
  3 al ' ASM, is there another way to extract the PROD archive logs and apply them to a cloned instance? (sending of newspapers without DR)
  
  The help is very appreciated.
  
  Kind regards
  Marjorie Dutta

  1. .... But the new restore a control file will delete the data files restored information?

  N ° provided that you do not have renamed, moved or abandoned any of the data files that were already copied in DEV. (also, subject that you did not add da new Production data between two backups - otherwise the new controlfile file will wait as datafile also to be present at DEV).
  You will do an incomplete recovery until a certain SNA / sequence # if information subsequent archivelogs beyond your point of recovery in the controlfile are redundant. In addition, a RESETLOGS would be done when you OPEN the database.

  2... how to know the locations of the game copied to the new location of the control file that is restored from the backup source database?

  What is the order CATALOG. In 9i, CATALOGUE could only of catalog datafilecopy. In 10g and more, you can BackupPieces CATALOGUER. Thus, it would "update" the controlfile (which is the RMAN Repository) with information about the BackupPieces that are present in a replacement / new location.
  See http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta011.htm#sthref230

  3. ... ASM, is there another way to extract the PROD archive logs and apply them to a cloned instance?

  According to the version you are using, ASMCMD has a 'cp' command to copy the files from the DSO for the operating system. However, you cannot use ASM to apply directly the archivelogs. You always use the 'RECOVER' of RMAN or SQL command line command.

• How to validate if my hot RMAN backup is good

  Hello
  
  We currently have hot backup RMAN set to our EBS R12. My problem is that we have not the test server where in
  I can test/simulate disaster recovery. How can I be sure my existing backup system full? without
  do the effective recovery or restoration? How will I know that my backup meets the complete Checkup, for example if I forgot to
  include control files? or if I do not have the file init.ora or spfile.

  Salvation;

  Is it not a dangerous command? What happens if I accidentally run without the command "commit"? It will replace my Prod database?

  I've used several times this command without any problem (Please check metalink note) and Yes he might try to restore your db on your database of existing, I suggest you be very careful when you type this command.

  PS: Run this command on the first test to try to make it work on prod. When you run this command, you will see some restoration line, it claims just as a restore with your existing backup database

• Hot RMAN backup requires archivelog all the time?

  Hi all

  consider: a dml operation is running in oracle database 11 g. After a while he completed and published a statement commit. Now, I took a full hot backup with rman. but backup of archivelog dint take (its must I know, but I want to know if we can do incomplete recovery using only the full backup and the database open with RESETLOGS option?

  Kindly let me know if we can do incomplete recovery using only full database backup, or we must need archivelog to open the database?

  Kind regards

  Tell your DATABASE BACKUP begins at 01:00 and ends at 01:50. At a minimum, you must save the Archivelogs from 01:00 for the first archivelolg after 01:50.  Technically you don't need the archivelogs in until 01:00. However, if you want to make a point in time recovery (which is a MUST for any production database), you should also save the archivelogs "earlier", which can be used with the last database backup.

  Your commitment does NOT guarantee that the database files are immediately updated - DBWR differs "lazily" writing in database files.  Your commitment is preserved in the online redo log. This should be archived an Archivelog and saved.

• EBS R12: How to clone an RMAN backup online?

  Hi hussein.
  
  I saw before in this forum, how to copy a database from an RMAN backup.
  
  The scenario is that I have a PROD on ProdServer instance.
  I want to create a DEV instance clone on the same ProdServer server, by using the RMAN backup.
  I want to clone the database only, this is just to check if my RMAN backup is restorable or legible or complete or etc.
  
  But I can't find the notes. :(
  
  Can you help me research it please?
  
  
  Thank you very much

• EBS 11i RMAN backup

  Hi all

  EBS 11i

  OEL 5

  I have rman backup of our database of EBS.

  I also have a single backup at oracle.

  Assuming that no patches have been applied, is the one-time backup of oracle home + backup rman, good enough to restore the database to a server disaster recovery?

  Can I still place adpreclone every day, for the rman backup to synchronize?

  Adpreclone is used to capture changes to the patches applied, or adding database files? or both?

  Please throw lights...

  Thank you very much

  JC

  It is not possible to have several databases with the ORACLE_SID even on the same host.

  The solution is that you have to put on separate hosts.

  Looks like it is exactly what you were asking.

  You need to connect to the TARGET, CATALOG & AUXILIARY of the rman prompt instance.
  You then run your script/command clone, which you claim you already know how to do.

• Waiting for redo log file missing when restore main database using RMAN backup that was taken on the database physical standby

  Here's my question after tons of research and test without have the right solutions.

  Target:

  (1) I have a 12.1.0.2 database unique main enterprise 'testdb' as database instance running on the server "node1".

  (2) I created physical standby database "stbydb" on the server "node2".

  (3) DataGuard running on the mode of MaxAvailability (SYNC) with roll forward in real time 12 default c apply.

  (4) primary database has 3 groups of one-man redo. (/oraredo/testdb/redo01.log redo02.log redo03.log)

  (5) I've created 4 standby redo logfiles (/oraredo/testdb/stby01.log stby02.log stby03.log stby04.log)

  (6) I do RMAN backup (database and archivelog) on the site of relief only.

  (7) I want to use this backup for full restore of the database on the primary database.

  He is a DR test to simulate the scenario that has lost every primary & Eve total servers.

  Here is how to save, on the database pending:

  (1) performance 'alter database recover managed standby database Cancel' to ensure that compatible data files

  (2) RMAN > backup database;

  (3) RMAN > backup archivelog all;

  I got elements of backup and copied to primary db Server something like:

  /Home/Oracle/backupset/o1_mf_nnndf_TAG20151002T133329_c0xq099p_.BKP (data files)

  /Home/Oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.BKP (spfile & controlfile)

  /Home/Oracle/backupset/o1_mf_annnn_TAG20151002T133357_c0xq15xf_.BKP (archivelogs)

  So here's how to restore, on the main site:

  I clean all the files (data files, controlfiles oder all gone).

  (1) restore spfile from pfile

  RMAN > startup nomount

  RMAN > restore spfile from pfile ' / home/oracle/pfile.txt' to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';

  (2) modify pfile to convert to db primary content. pFile shows below

  *.audit_file_dest='/opt/Oracle/DB/admin/testdb/adump '

  * .audit_trail = "db".

  * full = '12.1.0.2.0'

  *.control_files='/oradata/testdb/control01.ctl','/orafra/testdb/control02.ctl'

  * .db_block_size = 8192

  * .db_domain = "

  *.db_file_name_convert='/testdb/','/testdb /'

  * .db_name = "testdb".

  * .db_recovery_file_dest ='/ orafra'

  * .db_recovery_file_dest_size = 10737418240

  * .db_unique_name = "testdb".

  *.diagnostic_dest='/opt/Oracle/DB '

  * .fal_server = "stbydb".

  * .log_archive_config = 'dg_config = (testdb, stbydb)'

  * .log_archive_dest_2 = "service = stbydb SYNC valid_for = (ONLINE_LOGFILE, PRIMARY_ROLE) db_unique_name = stbydb'"

  * .log_archive_dest_state_2 = 'ENABLE '.

  *.log_file_name_convert='/testdb/','/testdb /'

  * .memory_target = 1800 m

  * .open_cursors = 300

  * runoff = 300

  * .remote_login_passwordfile = "EXCLUSIVE."

  * .standby_file_management = "AUTO".

  * .undo_tablespace = "UNDOTBS1.

  (3) restart db with updated file pfile

  SQLPLUS > create spfile from pfile='/home/oracle/pfile.txt'

  SQLPLUS > the judgment

  SQLPLUS > startup nomount

  (4) restore controlfile

  RMAN > restore primary controlfile to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';

  RMAN > change the editing of the database

  (5) all elements of backup catalog

  RMAN > catalog starts by ' / home/oracle/backupset / '.

  (6) restore and recover the database

  RMAN > restore database;

  RMAN > recover database until the SNA XXXXXX; (this YVERT is the maximum in archivelog backups that extends beyond the scn of the backup of the data file)

  (7) open resetlogs

  RMAN > alter database open resetlogs;

  Everything seems perfect, except one of the file log roll forward pending is not generated

  SQL > select * from v$ standby_log;

  ERROR:

  ORA-00308: cannot open archived log ' / oraredo/testdb/stby01.log'

  ORA-27037: unable to get file status

  Linux-x86_64 error: 2: no such file or directory

  Additional information: 3

  no selected line

  I intended to use the same backup to restore primary basic & helps record traffic and the downtime between them in the world of real output.

  So I have exactly the same steps (except STANDBY restore CONTROLFILE and not recover after database restore) to restore the database pending.

  And I got the same missing log file.

  The problem is:

  (1) complete alert.log filled with this error, not the concern here

  (2) now repeat it in real time apply won't work since the Party shall LGWR shows always "WAITING_FOR_LOG."

  (3) I can't delete and re-create this log file

  Then I tried several and found:

  The missing standby logfile was still 'ACTIVE' at present RMAN backup was made.

  For example, on db standby, under Group #4 (stby01.log) would be lost after the restoration.

  SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;

  GROUP # SEQUENCE # USED STATUS

  ---------- ---------- ---------- ----------

  4 19 ACTIVE 133632

  5 0 0 UNASSIGNED

  6 0 0 not ASSIGNED

  7 0 0 UNASSIGNED

  So until I take the backup, I tried on the primary database:

  SQL > alter system set log_archive_dest_state_2 = delay;

  This was the Group of standby_log side Eve #4 was released:

  SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;

  Then, the backup has been restored correctly without missing standby logfile.

  However, to change this primary database means break DataGuard protection when you perform the backup. It's not accept on the production environment.

  Finally, my real questions come:

  (1) what I do may not do on parameter change?

  (2) I know I can re-create the control file to redo before delete and then recreate after. Is there any simple/fast to avoid the standby logfile lost or recreate the lost one?

  I understand that there are a number of ways to circumvent this. Something to keep a copy of the log file waiting restoration progress and copy up one missing, etc, etc...

  And yes I always have done no real-time applies "to the aid of archived logfile" but is also not accept mode of protection of production.

  I just want proof that the design (which is displayed in a few oracle doc Doc ID 602299.1 is one of those) that backs up data backup works effectively and can be used to restore the two site. And it may be without spending more time to resume backups or put the load on the primary database to create the database before.

  Your idea is very much appreciated.

  Thank you!

  Hello

  1--> when I take via RMAN backup, RMAN does not redo log (ORL or SRL) file, so we cannot expect ORLs or SRL would be restored.

  2nd--> when we opened the ORL database should be deleted and created

  3rd--> Expecting, SRL should not be an issue.we should be able to do away with the fall.

  If you do, you can recreate the controlfile without waiting for redo log entry...

  If you still think it's something is not acceptable, you must have SR with support to analyze why he does not abandon SRL when controlfile_type is "underway".

  Thank you
