• Export vs rman as backup strategy

  I just joined new company and owner oracle DBA confessed that they have never used in all of their many years as a DBA Oracle rman.  Currently, they have 7 days of files dmp to export for each prod database.  I started to create backups rman for each prod dB and I asked if we can stop exports altogether.  Holder s/n, says exports are still needed in case we need to restore a table or in the case where we need to refresh a development/test environment.  I submit that rman can do and I communicated that I never used exports in a special or as needed case either to move an oracle dB between different operating systems or incompatible versions.  All export their production databases every night?  I've been an Oracle DBA since 10g but I've always been the unique oracle DBA in the shops/companies that I worked.  It is the first time I had a DBA experienced to work with.  I'm surprised actually kind of which my colleague has never used rman being that they are so widely experienced.  Dig deeper, they say they have used the NetApp as their backup method and they try to get configured in my current company that tells me will make rman irrelevant.  What do you think?

  My, my, my.  Your recent history of the display, you seem to have a lot of questions with your new business.

  In this case, you are partially right.  It is unacceptable for this "very experienced" s/n do not use rman and see no need of it.  If his backup strategy should only take nightly exports, it has been lucky and lives on borrowed time.  If the database is corrupted or lost, these exports don't you a good few until what you create - from scratch - a database of work.  And even then, only, you will have a point in time as a recovery point.

  NetApp is concerned, that I've never used but I understand that it is simply wraps around rman.  Perhaps, this can be handy.  Until the disaster where you also get trashed NetApp configurations.  No, when it comes back up, and more important again, recovering from a disaster, I want to work closely with the oracle supplied and approved method.  The extra layers less potentially go wrong, the better.

  If they want to continue taking exports every night, he certainly won't do any harm, as long as they realize that is secondary to the required rman backups.  All my databases are backed up with rman.  Some but not all also have nightly exports.  It depends on the requirements.  There are some things for which having a practice of export is better than to rely solely on rman.

• Oracle database backup basics

  May I ask, from a point of view, low tech a little question on the backup/restore of Oracle databases. Are there tools commonly used for backup of Oracle database? And have you ever encounter the snowman DBA / other places you have worked to make bad backups? I'd like to hear horror stories about what can and will hurt in oracle database backups? It is a simple process, or wrong - this easy ens at the end and things / featuring data etc.?
  And the second part of the question is if you're looking for auditing oracle backup processes, that you are looking 'good evidence' that this is done in line with the policy /strategy?

  >

  Are there specific reasons why backups become unnecessary, i.e. what goes wrong, when it comes to restoration, it is not restore.

  There may be two reasons. One, for example, backups are accidentally deleted, partially or completely. Another way may be the backup is marked as obsolete due to the retention or some operations strategy as resetlogs who could not leave the backups in use.

  I was also wondering how easy it is perhaps "missing data" when planning a backup DB with RMAN? Is this possible? Have you ever seen do, and if so is there any 'specific' part of a database that is often overlooked during examination of what to plan for in the backup task?

  What do you mean by "missing data"? It would be possible if you don't take care of backups that you plan.

• best backup strategy for the hotel management system

  Hello
  I have a fresh dba and I need to set a backup strategy for a HOTEL of Mr. must be available 24/7.
  Kindly help me and let me know if you need additional information.

  In your case the most appropriate b/s is with Rman. For this, you need to enable the database to archivelog mode. Each time, you need to copy past files archivelog (and rman full backup of database if you wish) generated after that full backup rman was made. Realize you must have as a minimum a full backup rman, all archivelogfiles has been generated since that time.
  There is also another way to take backup: hot backup. (read more in documentation Ora). But be aware that this will affect database performance while the backup is taken. And it would be a little more difficult for you.
  But if you're not allowed to activate mode archive so the only way is to take the datapump files each time.

• FRA backup strategy

  Hi Experts,
  

  BANNER
  --------------------------------------------------------------------------------
  Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
  PL/SQL Release 11.1.0.6.0 - Production
  CORE     11.1.0.6.0     Production
  TNS for HPUX: Version 11.1.0.6.0 - Production
  NLSRTL Version 11.1.0.6.0 - Production

  I would like to ask for some advice to place my backup in FRA.
  I read in a book that it is advisable not to put the backup archivelog in FRA since if something happen with the disk that store of FRA, everything will be gone. However the notion of FRA is logically a centralized backup.
  
  so, based on your experiences, what is the best way to use FRA to backup strategy?
  is it safe to put everything in FRA or we should divide again the backup archivelog to different location?
  
  Thank you

  Yes, it should be fine.

• 500GB database backup

  Hi guys,.
  
  Database: 10g
  OS: RedHat 4
  Log archive Mode: activate
  
  I want to implement the database of 500 GB daily, weekly and monthly backup strategy.
  
  Please suggest your opinion.
  
  Kind regards
  ESY.

  You save in order to recover.

  Backup strategy is determined by
  (a) how much downtime, I can afford when I need to recover
  (b) how many dataloss I can afford

  With regard to implementation, all you need to know about RMAN is in the manual online backup and restore, or you can buy the book by Matthew Hart.

• Help blackBerry Smartphones! Database backup error

  I can't back up my BB, I get the error code "Unable to save databases".  I've identified the problem as the "browser cache" database backup of databases individually in the advanced options.

  I deleted my browser cache and clean up the memory, but whenever I try to save my camera it gets so far and stops with the error message "cannot save data bases.

  Help please.

  Got a better solution that I found myself!

  If you CAN identify the problem database, and then follow the instructions in the first step of this link.  When you get to the part 4 of this, you must select the problem database and click clear.

  If the above statement is blocked, try acting below.

  Please make sure that you have created a tempfile more before performing this command as tablespace temp needs at a minimum a file.

  Otherwise, you can try as suggested by BalazsBerki.

• Database backups fail

  Hello Experts,
  
  Database backups fail due to compatibility issues, is the target database version 10.2.0.1, so RMAN version is running on 10.2.0.4.0, I have no idea how it happened and who did it before, now I have to take this issue... could you please give me suggestions on how to make RMANback 10.2.0.1 version.

  Make sure that you run the rman binary the same $ORACLE_HOME/bin as the database.

  If you run rman from a remote server, make a new 10.2.0.1 ORACLE_HOME install and run this House of Oracle rman.

• How to take database backup ASM/Instance?

  Hello
  
  I'm new with ASM. We take ASM/instance of database backup.
  
  can we have the idea to backup ASM?
  
  1. what components should be saved as database/Instance ASM / ASM all files?
  
  
  Please do the needful.
  
  Thank you
  Nitin

  Hello Nitin,

  First of all, you must understand that the RDBMS & ASM instance is different but yes, both are running on the same computer.

  ASM includes essentially two things: ASM instance (1) and the storage of the DSO (2).

  (1) ASM instance
  ------------------------

  That's just an instance when we do not backup but Yes if you want to keep the ASM instance configuration file then just follow these steps:

  [grid@host01 ~] $. oraenv
  ORACLE_SID = [+ ASM1]? + ASM1
  The basic Oracle for ORACLE_HOME=/u01/app/11.2.0/grid is/u01/app/grid

  SQL > create pfile='/home/grid/init+ASM1.ora' of spfile;

  Created file.

  (2) ASM STORAGE
  -------------------------

  -Storage ASM includes essentially ASM starts, namely new set of disks.

  -Whenever we do not create ASM diskgroup diskgroup contains still three things:

  (a) disc ASM
  (b) models and metadata
  (c) the ASM files (essentially datafile or all database files)

  -We take backup of two things on three things in ASM diskgroup:

  (1) ASM files - with RMAN because these are files of database.
  (2) ASM diskgroup models & metadata - with the MD_BACKUP of ASMCMD command.

  Now, MD_BACKUP will create a backup as your specified location file and this file will includes all models and metadata of the diskgroup. Benefits of taking diskgroup metadata are, if we lost the diskgroup, so we do not worry some details configuration command MD_RESTORE use to recreate the diskgroup with the same configuration. But remember that it does not restore the data file or any other file that was there on the diskgroup going to use RMAN to restore the missing files.

  See the example:

  ASMCMD > lsdg

  State Type sector Rebal to Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Voting_files name of the block
  EXTERN MOUNTED N 512 4096 1048576 11742 11643 0 11643 0 N ABC /.

• Backup strategy questions

  Hello

  We are trying to determine our backup strategy for the guest operating system. We currently use vRangerPro to our guest operating system with a retention time of 14 days with 2 good backup copies. I know it works and have tested it.

  However, we also have Symantec Backup Exec System Recovery installed in each guest operating system and make backups in this way as well. I have restored the livestate to a new guest operating system image and it works, but VMware support this? Did someone else do this way as well? Is this exaggeration and I really need to do backups of vRangerPro?

  Please advise?

  Thank you!

  Kev77

  Exactly.  With some of the bulk of businesses like esxpress backup coming out with new versions, we can proceed with their redundant backups of files soon.  We'll see.  Its nice to have two, one for a major disaster and the file level for small documents that remove the stupid users.

  How can I use Veritas NetBackup to backup my database of catalog RMAN? I need to stop this catalog DB in order to save it. How can I plan with NetBackup?
  
  Thanks in advance.

  Hello

  Normally, the catalog database backup is currently off cause is very small database and may remain unavailable for a few minutes. In my company, we use netbackup.
  Try to schedule an offline backup of the database via the Netbackup graphical interface, it will generate RMAN scripts bpstart_notify. YOUR_POLICY_NAME and bpend_notify. YOUR_POLICY_NAME under/usr/openv/netbackup/bin/if you use SOLARIS.

  Kind regards

• backup database - backup multiple sets of 1 piece 1 statement each

  Hi all!

  I have an ORACLE database 11 GR 1 material running on RHEL X86_64 5.7. The size of the database is approximately 800 GB.

  This is the current configuration of RMAN:

  CONFIGURE REDUNDANCY 2 RETENTION STRATEGY;

  CONFIGURE BACKUP OPTIMIZATION

  SET UP DEFAULT DISK DEVICE TYPE;

  CONFIGURE CONTROLFILE AUTOBACKUP ON;

  CONFIGURE CONTROLFILE AUTOBACKUP FORMAT for DEVICE TYPE DISK TO ' / d02/rman_backups/%T_%F';

  SET UP THE DEVICE TYPE DISK PARALLELISM 1 BACKUP TO COMPRESSED BACKUPSET 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 DEVICE TYPE DISK FORMAT ' / d02/rman_backups/%T_%U' MAXPIECESIZE 60 G;

  CONFIGURE MAXSETSIZE TO UNLIMITED; # by default

  CONFIGURE ENCRYPTION OF DATABASE # by default

  CONFIGURE THE ENCRYPTION ALGORITHM "AES128"; # by default

  CONFIGURE THE "ZLIB" COMPRESSION ALGORITHM

  CONFIGURE THE NONE ARCHIVELOG DELETION POLICY; # by default

  CONFIGURE SNAPSHOT CONTROLFILE NAME TO ' / d01/dev/db/tech_st/11.1.0/dbs/snapcf_DEV.f'; # by default

  It's my 'RUN' block to create a single full backup:

  RUN

  {

  SHUTDOWN IMMEDIATE;

  BOOTABLE MEDIA;

  BACKUP DATABASE;

  OBSOLETE REPORT;

  REMOVE OBSOLETE;

  ALTER DATABASE OPEN;

  }

  Backup of days RMAN created 1 backup set made up of 5 pieces: 4 pieces of 60GB and 1 piece of 42 GB as well as saving the file spfile and control... for me this is the expected behavior.

  But today, RMAN created 34 games backup of 1 piece of each... parts are no more than 7 GB.

  It is the output for control of BACKUP of LIST SUMMARY:

  Please help me to reconfigure RMAN to create the backup set 1, composed by the "n" backup items.

  I appreciate your time and your help nicely.

  MAXSETSIZEsizeSpec

  Specifies a maximum size for a backup (as shown in example 2-17). RMAN limit all backup sets to this size. It is possible for a game span multiple tapes, sort of blocks from each data file is written to multiple backup tapes. If a tape of a multivolume backup set fails, then you lose the data on all bands, rather than a single one. Because a backup set always includes an entire file rather than the part of a file, you can use MAXSETSIZE to specify that each backup set should fit on a single tape. Specify the size in bytes (default), kilobytes ( K ), Mo ( M ), or gigabytes ( G ). For example, to limit a game to 3 MB of backup, specify MAXSETSIZE 3M . The default size is expressed in bytes, rounded to kilobytes. For example, MAXSETSIZE 3000 is rounded to 2 k (2048 bytes). The minimum value must be greater than or equal to the database block size. The number of files in each default backup set is determined by FILESPERSET , which by default is 64. When you specify MAXSETSIZE , RMAN attempts to limit the size in bytes of the backup sets according to the MAXSETSIZE parameter. The limit on the number of files in a backup set applies even if the total size of the backup set that results is lower to MAXSETSIZE . Note: This option will result in an error if used with BACKUP AS COPY . If you run BACKUP AS COPY on a channel that has MAXSETSIZE value, then MAXSETSIZE is ignored in silent mode.

• Smartphones blackBerry unable to backup (Options memory cleaner): database backup error

  Hi all!

  I need help.  I'm trying to make a backup of my "BOLD", but when the procedure happens to Options cleaner memory, the process stops and I get the error "Error backup database".

  All the ideas from the pros?

  Thank you!
  Dan

  Hi and welcome to the forums!

  Cleaner memory in my opinion is misnamed and abusively.

  The cleaner memory formats a Government on the memory wipe. He won't

  improve or move memory back and more quickly to the BB. Therefore, I completely

  stopped using it and it was not in my last update.

  Try to turn the option off, battery pull, then run a backup.

  IF it doesn't go away, I'll be back with right clear procedure of database.

  Thank you

  No data will be lost when you do the following: remove the battery while the device is activated.
  Remplacer replace after one minute, let the device reboot 1-3 min, see if the problem is corrected.
