• controlfile autobackup and DBID

  Hi all

  If we are to restore RMAN controlfile autobackup controlfile, we must define the DBID. Otherwise, we can specify the full of the controlfile autobackup path if we do not have a DBID. My question is how exactly RMAN determines the proper backup of just the ID file? Is this something like this:

  RMAN goes to the default backup location - $ORACLE_HOME/dbs

  Examines all backups for DBID that we put

  Then restore the backup file appropriate?

  Kind regards

  Vinod

  The file name by default in $ORACLE_HOME/dbs includes the DBID.

  If you use db_recovery_file_dest (i.e. an MRE), record going under the DB_UNIQUE_NAME folder

• Clarification on controlfile autobackup

  Friends, I read in one of the famous books of RMAN that "when we add new data files to storage, server process initiates controlfile autobackup'.If controlfile autobackup is set on"ON"in parameter of RMAN. I tested in my dummy environment but did not find any truth in it, I checked for alert log and did not find any backup controlfile after adding data files. No indication in this regard will be appreciated.

  > Data files how much I add

  A few.  An accurate count is not documented.  Oracle monitors the number of changes in the course of an interval.  I know, it does not create a new autobackup controlfile for each data file added in a 5 minute window, but only at the end of this window.  But I don't know if that 5 minutes is a documented fact or a result of some heuristics.  The actual duration of your environment may vary.

• controlfile autobackup does not work on 11g R2

  Hi all
  
  in database 11g R2 on windows and linux os (linux machine is a virtual machine), RMAN controlfile autobackup does not work. I'm this setting on IT and adding a tablespace for the database, but there is no new files backup controlfile.
  
  Oracle documentation, I know that if you set THE controlfile autobackup on RMAN, each structural change in the database control file is saved to automaticlly. Also in the 11g R1 version I did and saw new backup controlfile is created. (to see the new backup, I use the backup RMAN list command).
  
  I check in the machine 2 windows machines and different virtual linux but for 11 g r2 there is no new backup. I couldn't find anything about it in the Oracle documentation.
  
  will there be a new change that I don't know? I will appriciate to get answers.

  I see in the GR 11, 2 backup and recovery Reference Guide, page 98, there is a paragraph as follows:

  "Beginning with Oracle 11 g Release 2, RMAN creates a backup file auto single covering the whole of the structural changes that took place within minutes of each other rather than create a new backup of the controlfile on each structural change to the database."

  I checked all my databases again, and there is now a backup of contolfile for each of them. It seems that there is now a delay of a few minutes for the backup of the controlfile. Can you watch it again to see if you can see them on your databases?

• controlfile autobackup in 11.2.0.1

  Hello
  
  I wonder what that means below?
  
  http://download.Oracle.com/docs/CD/E11882_01/backup.112/e10643/rcmsynta010.htm#RCMRF113
  
  Starting with Oracle 11 g Release 2, RMAN creates a backup file auto single covering the whole of the structural changes that took place within minutes of each other rather than create a new backup of the controlfile on each structural change to the database.
  
  Thank you

  Dear Markus Waldorf,

  For example, when you add a data file to a tablespace in the alert.log file, it says "start autobackup controlfile. According to the the Recovery Manager retention policy, these controlfiles are stored in the directory appropriate for this period. So when he wants to create a controlfile autobackup option, it creates a new rather than to modify the last being.

  So when there's a controlfile autobackup has been created by the recovery, after a few minutes of this, Manager when he needs to create a new, it will not create the controlfile (automatic backup).

  That's what I realized with this sentence.

  Kind regards.

• to find checkpoint_change # to controlfile - autobackup vs Ckp_SCN #.

  T1) why the checkpoint_change # in the database of v$ remains the same as before and yet datafiles checkpoint_change # has changed?

  Q2) why is the SNA cash at the same autobackup later then the checkpoint_change # in the database of v$?

  Q3) how to find the last checkpoint_change # in the current controlfile then?

  Q4) what is the use of the checkpoint_change # v$ database used since then? (because it does not reflect the last checkpoint #-v$ datafile.checkpoint_change # is more accurate)?

  Hello

  v$ database.checkpoint_change # Q1) is loaded from the record section of the controlfile right?
  v$ datafile.checkpoint_change # Q2) is also responsible for controlfile right?

  No, v$ datafile would be real datafile (AFAIK - as the nucleus is different for this) bonano$ x database $ kcc % structure (so she keeps track of more than all databases - my point of view more controlfile).

  (T3) - the v$ database.checkpoint_change # is responsible of the controlfile and then it is used to match against what?

  In your example above SNA for v$ database is 100, CPN for v$ datafile 6 is 98 and the v$ datafile_header is 97.  So, how the v$ database.checkpoint_change # a role here?  I mean just by comparing v$ datafile YVERT and v$ datafile_header SNA, we will know that there is a difference and a recovery is necessary.

  Why do we still need to look at v$ database.checkpoint_change #?

  v$ database is at the highest level of level/parent, and v$ datafile (x$ kcvdf) is a subset of the audit is made/done. v$ datafile_header (her picking up x$ kcvfh) both are different structures (If you dig the 'C' code header files so you can get to know), so it would play a break point (or) updates made to different internal control points are made by CKPT processes.  Now, you don't ask me on internal control points when and that process, so that you get support and view the code (it is people development oracle).

  or spend some time x$ active_ckpt how it gets changed and everything what you can observe from the validations and cheating LGWR (I can't go beyond that).

  Q4) in my scenario above, the v$ database.checkpoint_change # is significantly different from the v$ datafile and v$ datafile_header, but in reality no recovery is necessary.

  v$ database 4177813

  v$ datafile 4189456

  v$ datafile_header 4189456

  How does v$ database.checkpoint_change # here help to determine if a recovery is needed or not so?

  I did not sit that is it his ' necessary recovery or non-compulsory. When you try to open it will provide information - based consistenct check with the data files (v$ datafile and v$ datafile_header) else believe me your cannot open it (as much my testing goes).

  Now, don't say you took the backup and clone of another server, when it is permissible for you open resetlogs, so what is this case/situation, since the db you has opened, since you find no different to SNA (v$ datafile and v$ datafile_header) so he could continue with the new incarnation (new activation id #).  About the incarnation and activation id visit google or one of my blog where I have provided information on that.

  v$ Database.checkpoint_change #-does not say any substance above recovery, its comparison with (v$ datafile and v$ datafile_header) would help on the recovery.

  If you come back and say only above will be enough to decide that if recovery is necessary or not, so I can't decide on this, this is the /algorithm code, if you ask for reasons simply understand that we have below records

  CHECKPOINT PROGRESS RECORD

  EXTENDED ENTRY database... which contains the information

  Automatic backup control date)

  RECORDS IN DATA FILE

  MULTI INSTANCE REDO APPLY RECORD... It's needs to check that all committed or rollback - in terms of CARS (so all the code depends on two or three columns of two control points and can't decide on recovery - according to my knowledge /understanding)

  ARCHIVES NEWSPAPER RECORDS... If SNA isn't matches he can check what archives with SNA which are recovery - on this basis he asks what Archives need to apply.

  Hope this helps and ask you to spend some time, you will understand things.

  Can I recover my database?

  File "o1_mf_ncsnf_TAG20141110T012555_b5zkrhqp_.bkp" is probably a backup controlfile.

  Use RESTORE CONTROLFILE FROM "path_to_file".

  (Note: you must SET DBID before RESTORE you CONTROLFILE because Oracle uses the DBID to test if the controlfile is the same database.)  You can obtain the DBID of newspapers of the previous series of rman or your documentation)

• Controlfile autobackup without RMAN recovery

  
  Hello

  I'm trying to restore a customer database of RMAN backups for the same instance name and DBID but a different server with a different directory structure.

  It is a full RMAN backup, but the log shows that the controlfile is supported only through current, not with autobackup backup controlfile.

  I have built directories bdump standard and created a directory of data, file a copy of the init.ora in order to take into account locations suitable for the dump file, the archive logs and the controlfiles and also added in the settings db_file_name_convert and log_file_name_convert to map the original directory structure noted in the backup rman to the new locations.

  I understand that you cannot restore the backup controlfile, but was under the impression that you can set the format and restore the controlfile but am not having luck with this-

  I do not know what operating system, customers use

  I need to prove the process works and what I'm looking for is correct, before I can go back to them and ask what they sent.

  Yes, but operating systems may be incompatible. For example, if yours is Linux, and one of the clients is AIX, it would not work, and you get the error that you actually get.

• RMAN controlfile autobackup

  How ramn will be notified of changes in the structure of the database... which backgound process will even update...

  Hello

  As said above, whenever a structural change happens in the DB... it will be updated in controlfile.similarlly whenever you connect the rman, it get full details of the control file DB. so, if you have configured the automatic backup of the file control then controlfile will be upward automatically saved whenever you issue the backup command.
  by default, rman does not have any backup... Yo has set up or have to plan the rman backup...

  1 direct the response is not possible (as you want to edit it - existing tag name) you must ensure that you can then give him only by using backup taken tag keyword followed by the name of tag

• AUTOMATICA Controlfile backup?

  Hello

  I'm using Oracle 11.2.0.3 on Oracle Linux 5.

  My config RMAN States

  CONFIGURE CONTROLFILE AUTOBACKUP ON;

  Now according to the documentation,

  (a) at any time, if I take a backup of files dbf SYYTEM it will automatically backup controlfile, spfile, and

  (b) at any time let's say I create a new TS or add a new data file to an existing TS, it will take a controlfile backup due to structural changes to the database;

  My doubt is related to point (b) above, even if I created a new TS, I saw that it does not automatically trigger a backup controlfile. Can I assume that Oracle will eventually do so after a while or my understanding is incorrect? Getting you guys able to see the play of backup controlfile generated as soon as new TS is created?

  Learner

  In 10g, it would create an automatic backup whenever a structural change was made. So, if you have added the files of 10 data within 30 minutes, it would create 10 record.

  11 g, they have changed the 'intelligence' to wait and see if you do several structural changes in a short time before deciding to do an automatic backup.

  (or was it 9i and 10g, I don't remember now)  It's the change of 11g over 10g

• strange error with configure snapshot controlfie

  If I put the path snapshot controlfile to the db name hardcoded in the path, it works:

  CONFIGURE SNAPSHOT CONTROLFILE NAME TO ' / var/backup/IDB00246/snapcf_%d.f';

  From control file and SPFILE Autobackup 10 December 14
  room handle=/var/backup/IDB00246/controlc-2380395869-20141210-05.ctl comment = NONE
  Control finished and Autobackup SPFILE file to 10 December 14

  RMAN >

  But if I put the path using %d, he doesn't seem to like it:

  CONFIGURE SNAPSHOT CONTROLFILE NAME TO ' / var/backup/%d/snapcf_%d.f';

  From control file and SPFILE Autobackup 10 December 14

  Complete recovery manager.

  I can use %d for these two orders with no problems:

  FORMAT 1 CONFIGURE CHANNEL DEVICE TYPE DISK MAXOPENFILES ' / var/backup/%d/dumps%d_%T_s%s_p%p.bus';

  CONFIGURE CONTROLFILE AUTOBACKUP FORMAT for DEVICE TYPE DISK TO ' / var/backup/%d/control%F.ctl';

  Then why can't it be used for snapshot controlfile?

  On the snapshot Controlfile: when RMAN must resynchronize the catalog of recovery with a consistent read version of the control file, it creates a TEMPORARY snapshot control file. RMAN needs a snapshot control file when the resynchronization with recovery catalog or before you perform a backup of the current control file.

  Why you should use variables in a temporary file internal?

  RMAN does not have a snapshot unique to each backup file, RMAN automatically overwrites the file if it exists. You can use the same file and location all the time, for example ' / u01/app/oracle/product/11.2.0/dbhome_1/dbs/snapcf_dborcl.f'

  If I put the path snapshot controlfile to the db name hardcoded in the path, it works:

  CONFIGURE SNAPSHOT CONTROLFILE NAME TO ' / var/backup/IDB00246/snapcf_%d.f';

  You have this file "snapcf_%d.f" not "snapcf_IDB00246.f" in "/ var/backup/IDB00246 / ', because 'CONFIGURE SNAPSHOT CONTROLFILE NAME' does not support variables.

  You must create a file snapshot controlfile name unique for each database.

• RMAN backup runs twice (sequential) even if it is not configured in this way

  Hello

  I started experimenting with RMAN as another way for backup (currently we use backup with storage). I'm running a few tests every day to check the overhead and time there and also check the storage space needed for our system.

  At first, everything seems fine, I tested a few default options and then started to configure the RMAN suite better our needs.

  The problem:

  During my recent tests found that RMAN's backup of my database twice, but I could not find out where I configure it to run this way.

  I even put a basic Vanilla with the same features, but it produces a single backup set.

  I enclose my test RMAN environment configuration, and I hope that someone will be able to indicate where I configured RMAN to do 2 sets of backup.

  RMAN > show all.

  Db_unique_name MSCA RMAN database configuration settings are:

  CONFIGURE REDUNDANCY 1 RETENTION STRATEGY; # by default

  CONFIGURE BACKUP OPTIMIZATION # by default

  SET UP DEFAULT DISK DEVICE TYPE; # by default

  CONFIGURE CONTROLFILE AUTOBACKUP ON;

  CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO "%F" # by default

  SET UP THE DEVICE TYPE DISK BACKUP FOR PARALLELISM BACKUPSET TABLET 1 TYPE;

  CONFIGURE BACKUP OF DATA TO DISK FILE TYPE DEVICE TO 1; # by default

  CONFIGURE BACKUP ARCHIVELOG FOR DEVICE TYPE DISK TO 1; # by default

  CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT ' / oracle/MSCA/db/rman_bkup/MSCA/df_%d_%T_%U.rmn' MAXPIECESIZE 10 G;

  CONFIGURE MAXSETSIZE TO UNLIMITED; # by default

  CONFIGURE ENCRYPTION OF DATABASE # by default

  CONFIGURE THE ENCRYPTION ALGORITHM "AES128"; # by default

  CONFIGURE COMPRESSION ALGORITHM 'BASIC' AND 'DEFAULT' LIBERATION OPTIMIZE FOR TRUE LOAD; # by default

  CONFIGURE THE NONE ARCHIVELOG DELETION POLICY; # by default

  CONFIGURE SNAPSHOT CONTROLFILE NAME TO ' / oracle/MSCA/db/rman_bkup/msca_dbs/snapcf_MSCA.f';

  Here is the result of the end of the backup set 1. You can see it took 2 hours, then immediately, he began another work of backup (highlighted in RED)

  channel ORA_DISK_1: finished piece 5 to 02 - OCT-14

  piece handle=/oracle/MSCA/db/rman_bkup/MSCA/df_MSCA_20140902_09phg6h0_5_1.rmn tag = TAG20140902T115927 comment = NONE

  channel ORA_DISK_1: full game backup, duration: 02:05:08

  channel ORA_DISK_1: from complete compressed datafile backup set

  Thank you

  You present, evidence that it is '2 backups of a database'.  I see two backupsets, each with a different set of data files in your ad.  If the backup is spanning two backupsets - you probably more than 64 files of data.
