• 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;

  GROUP # SEQUENCE # USED STATUS

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

  4 0 0 UNASSIGNED

  5 0 0 UNASSIGNED

  6 0 0 not ASSIGNED

  7 0 0 UNASSIGNED

  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".

• Restore the RMAN backup on another server

  Hello

  ENV: Oracle 10 g 2 64 bit, RHEL 5.8 64 bit on ASM, Database size = ~ 1.3 to

  Backup RMAN of PROD will FRA and then backed up to tape. I have limited access to the PROD because it is maintained by 3rd party.

  My client is planning to move this database on their own datacenter (from the 3rd party data center). For test purposes, I asked DBA of 3rd party to provide us with an export of drawings required data pump. Export takes about 8 hours, and the import takes the same time to the new location. To copy the files exported to new locations takes another few hours (over the network). The total size of the dump file is around 500 GB. Thus, a whole cycle of Export-Import-copy takes about ~ 20 + Hrs.

  I want to try another option to reduce the time required for the updating of the database of PROD and which is "use RMAN backup of PROD ' and restore it on the data center server. RMAN full backup takes ~ 4hrs PROD and the restoration should be at the same time (new server has better and faster HW, storage with a SSD). I found this thread very useful on the Oracle Forms on this topic:

  Restore backup RMAN on another server

  This thread contains very good example for a restoration of database on the file system.

  I have a bit of confusion because my database uses ASM. The default location of the backups in PROD is FRA (on ASM == > db_recovery_file_dest = + FRA ). If I understand correctly, the RMAN backup must be in the same place where he was on the PROD Server - i.e. the diskgroup FRA.

  If I get a copy of the part 3 RMAN backup, how would I copy on FRA?

  OR can / should I just change the init parameter "db_recovery_file_dest" on the new server to point to the file system directory where the backup (say "/ ora_backup") and RMAN will pick up and restore the database?

  Please advise!

  Best regards

  You can restore the backup files to any location, then you must configure the channel using the "CONFIGURE CHANNEL device type disk format 'new location ';

• Import of schemas and tables of RMAN backup

  Hi all

  I have here are 3 requirements:

  (1) is it possible that I can import a single table using RMAN backup, because I have no more than one day of EXPDP dump file and the requirement is to store the data of three days.

  (2) is it possible that I can import a single SCHEMA using RMAN backup, because I have no more than one day of EXPDP dump file and the requirement is to store the data of three days.

  (3) can I import a package from the RMAN backup?

  I have incremental backup of level 1 and level 0.

  My database is 11.2.0.3

  Thank you and best regards,

  Mukesh

  Hi Mukesh,

  All of your needs can be met with output up to 11g using RMAN database, but beyond of 12 c, you can restore a single table RMAN backup (RMAN BACK TABLE new feature to the 12 c (Doc ID 1521524.1) Oracle database). For your condition impdp/expdp is the best Utilities option until oracle provided up to version 11 g.

  I hope this helps.

• ASM files using RMAN backupset backup system migration

  my script to backup daily as below

  backup in the format of compressed backupset "$BACKUP_DIR/db_%U" database

  backup current controlfile "$BACKUP_DIR/Cont_%U" format

  backup as backupset archivelog Tablet format all '$BACKUP_DIR/arch_%U ';

  It is possible to migrate the database ASM uses above backup backupset RMAN?

  because I restore the database is restored, the problem is when he try to recover it, unable to understand the archivelog and redlog files.

  Hello

  in fact, after I moved the pieces to another server and called with RMAN (including the archivelog files)

  1. When you have moved to another server, then at this stage - my hypothesis, you have restored the controlfile to fileystem and mounted

  2. as you said moved to another server, the parts are on file system or (ASM location - still the second server can see)? If your answer is no, when you catalog now, controfile must save it with the file system path but not ASM

  Note - If you're still see ASM path then. the migration of the ASM to no - asm (the steps are not correct) logically you went wrong and implementation/execution thrown.

  3. provide the plan and execution - what you did (while we can fix). To be honest, while on the move DB to non - asm, why you need first to recovery? Tell me about your backup procedure itself is gone bad.

  To be honest, you try to database host of ASM no - asm as backup in function (but no real process of moving).  Therefore, in spite of the use of rman backup in dual function duplication... you have implemented in the wrong approach.

  This is the reason why I have provided the link and examples to understand.

  Hope you understand now.

  Concerning

• How knowledge/check if the RMAN backup was performed using a current control file or database catalog?

  Hello

  How knowledge/check if the RMAN backup was performed using a current control file or database catalog? I mean RMAN prompt or sqlplus is it possible to know.

  Thank you

  You're welcome my friend

  You can see them using two methods.

  as I mentioned above, you can see them connect to the catalog database and you can query using the view that I sent

  http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmreprt.htm#BRADV89601

  the other method is the list command, you must use the list command after connecting using rman "rman target / catalog cat_user/cat_pass@catdbtns" command

  http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmreprt.htm#BRADV8136

  Check the value of the control_file_record_keep_time parameter. The default value is 7 days. in the output of the list command, if you can see the old backups to the value, you must be sure that the backup information comes from the catalogue database

  SELECT * FROM parameter $ v where name = 'control_file_record_keep_time '.

  an example of command list

  the list of completed database before backup ' sysdate-10'.

  Concerning

• Using tape for RMAN backup concerns

  Dear all,

  I use the library of networker for rman backup. I have some problem/question about what I don't use catalog db. Here it goes:

  1. think you that automatic backup controlfile should set to strip? or better to keep in the disc.

  2. How can I configure autoback controlfile format on TAPE?

  3. If I need to restore control to another HOST file, how can we do this?

  4. I've read a few books we can't CATALOG element of tape backup. If it's the fact that, after the disaster, how do I Catalog backup piece and restore this backup piece in another host?

  Kind regards

  Hello

  1 when RMAN channel tape is allocated when running RMAN backup, autobackup controlfile will be created in the Ribbon to place on the disc. If structural change to the database is made, for example by adding a new data file, then the controlfile autobackup will be created in the disk, regardless of the device type of the default RMAN configuration.

  Control file autobackup after structural changes of data and the Type of device SBT_TAPE (Doc ID 1190354.1)

  2. set below:

  RMAN > CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE 'SBT_TAPE' TO '%F ';

  3. If the automatic backup location is not the default location and then set the location first.

  Use this command to set the location:

  RMAN > SET FORMAT FOR DEVICE TYPE SBT_TAPE AUTOBACKUP CONTROLFILE to '< auto="" backup="" format="">';

  Then use the command

  RMAN > restore controlfile on "" automatic backup;

  4. starting with 10 g, it is possible to use the rman CATALOG command to add backuppieces stored in the disc to the rman repository. But it is not possible to use the order CATALOG for items stored on TAPE backup, but note below explains undocumented commands to add backuppieces stored in the RIBBON for the repository.

  Thank you
