A question quick rman

• A question about rman.

  Hello

  My database is in log mode archive, we schedule rman to backup all archive logs and "remove all entries ', every 20 minutes; We backup of database Sunday full and level 1 rest of every day.

  If rman, I have set it up as: 'CONFIGURE RETENTION POLICY to REDUNDANCY 1 '.

  I know Oracle will keep a copy of the backup database and make additional copies of backups as "obsolete."

  Here the question: how to make the mark of oracle these obsolete archive log backups ?

  (if I like "CONFIGURE RETENTION POLICY to RECOVERY OF 2 DAYS WINDOW;", it is easy to understand that all backup of archive logs 2 day window, will be marked obsolete) »

  (why I'm asking, because in my backup rman script, it will remove obsolete at the end of backup, we don't want to keep these backups of logs archive forever).

  Thank you very much!

  Hi again,

  Please see the Oracle Doc for more information.

  "How RMAN retention policy obsolete incremental Backupsets and files Archivelog (Doc ID 206862.1)"

  Thank you

  Hello

  There are two possible settings for the retention policy:

  • Redundancy
  • Recovery window

  Oracle will ensure these settings before you mark whatever it is obsolete.

• Question about RMAN

  Oracle version: Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production

  OEM, I see an alert indicating that we are short of recovery are space:

  db_recovery_file_dest_size of XYZ bytes is used and has ABC remaining available bytes

  I found the thread db_recovery_file_dest_size 37580963840 bytes is 98.29% used and 6442 which recommends to do following:

  RMAN target /.

  overlap archivelog all;

  remove expired archivelog all;

  My question: is it safe to perform this action at any time?

  Thank you

  Yes.

  Also you would be better only to use RMAN to maintenance spare and avoid to delete files using commands in the OS, because this is not reflected in the RMAN Repository.

• Question of RMAN restore points

  Hello

  I'm on the 11.2.0.3 Oracle database. Currently, we have RMAN scripts that make incremental backups and weekly/monthly full daily. My daily script is as below:

  {
   allocate channel t1 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
   allocate channel t2 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
   allocate channel t3 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
   backup format 'prod_dailybackup_%d_%s_%t' incremental level 1 database;
   backup format 'prodarchbackup_%d_%s_%t' archivelog all not backed up 1 times;
   crosscheck backup;
   crosscheck archivelog all;
   delete noprompt obsolete;
   delete noprompt expired backup;
   delete noprompt expired archivelog all;
   report schema;
   release channel t1;
   release channel t2;
   release channel t3;
  }
  

  And the script to backup weekly as below:

  {
   allocate channel t1 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
   allocate channel t2 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
   allocate channel t3 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
   backup incremental level 0 format 'prod_weeklybackup_%d_%s_%t'  database;
   backup format 'prodarchbackup_%d_%s_%t' archivelog all not backed up 1 times;
   release channel t1;
   release channel t2;
   release channel t3;
  }
  

  My two questions are:

  1. can I add a "restore point" for the backup script daily, without the clause "keep until the"?

  2. can I add a restore point whose name is generated dynamically, for weekly backup, for example: weekly_rest_point_13082013, including therefore the current date?

  Hello

  1. can I add a "restore point" for the backup script daily, without the clause "keep until the"?

  I think not, is to keep to the required field

  2. can I add a restore point whose name is generated dynamically, for weekly backup, for example: weekly_rest_point_13082013, including therefore the current date?

  Don't you cannot assign the dynamic name in name of the restore point.

  It should be as it is to say

• Question on RMAN

  An excerpt from the next thread
  
  Re: RMAN without tape
  
  Can I use RMAN without a configured tape device?
  Yes, but you will not be able to use the Oracle backups of suggests straight out of the box
  
  What does that mean? Are bands the average recommended oracle backups?
  Are there difficulties to backup to disk?

  This response (or the context in which it is given) is bad.

  Actually, the 'normal' or 'popular' approach is today RMAN disk. Think of the FlashRecoveryArea - a perfect RMAN, the implementation of the disk.
  Disk is cheap. The disk recovery is quick.
  That said, who, once an RMAN backup to disk is made, the backup should go to band - but copy the Strip can be an individual task / deferred. This copy of band is for protection against the failure of the FRA.

• Question of RMAN

  Hi all

  Could you get it someone please let me know what is the difference between incremental backup using rman and rman optimization. I searched a lot in the Oracle documentation but could not get it.

  Kind regards

  Michel

  RMAN > backup optimization;

  RMAN > backup optimization;

  When you enable backup optimization, backup using rman command will skip backup of any file (datafile, archivelog or backup sets) if it has not changed or it is already saved. If your subsequent backup will save space.

  Incremental backups RMAN backup datafile only blocks changed since a previous backup specified. You can perform incremental backups of databases, individual storage spaces or data files.

• Question about RMAN DUPLICATE command

  Oracle version: 10.2
  Operating system: Solaris 10
  
  To create a physical standby DB, I'll take full DB more backup archivelog on main site and copy it to the location of the previous day.
  I'm going to standby mode,
  

  startup nomount pfile=/path/init.ora
  rman target sys/password@primDB auxiliary /
  
  RMAN> run {
  allocate channel t1 device type disk;
  allocate auxiliary channel t2 device type disk;
  duplicate target database for standby nofilenamecheck;
  }

  1. is it true that I need to keep the full backup on the main site when you run the RMAN DUPLICATE backup server? In the affirmative. Why? We have already copied the full backup to the backup site. Right?
  
  2. why the command DORECOVER is optional?
  
  3. several archived newspapers may have been generated after that full backups have been copied to the backup site. When you run the backup site COPY command, RMAN will extract the info again newly generated primary and apply automatically in standby mode?

  Hello;

  I keep the RMAN backup on the primary until the copy is complete, so my RMAN catalog know about it. Sound cleaner this way. What magic RMAN can or can not do with it is not very important IMHO.
  Don't forget that the news of the eve doesn't have to be registered with RMAN, because it is the same database as the main. However you can use a tape with the method too, so it's probably more to do with not having to repeat the same backup if you make a mistake.

  I've never had to use a DORECOVER to a double never. Completing this task at least 30 times and I think 'optional' is not a word strong enough. According to the doc DORECOVER specifies that RMAN should recover the database after it is created. I've never had to use it. See this doc for more information:

  http://docs.Oracle.com/CD/B19306_01/backup.102/b14194/rcmsynta028.htm

  On move any what archiving log new expectations before to start the double so the news of the day before can start working immediately, without additional measures. Usually the Data Guard will begin apply immediately and have RMAN does not do anything. None of the notes has any special note for additional archives moving after starting two copies. RMAN duplicates and Data Guard apply struggling upward.

  Here are my notes on this topic: (these works on Oracle 10 or 11 of the Oracle)

• Using the question of RMAN cloning

  DB version: 10 gr 2
  Operating system: Solaris
  We are thinking of cloning a database taking his full backup can

  rman target / auxillary sys/mypass@auxdb                    --- Done at Primary DB
  rman> duplicate target database to "smdprod" NOFILENAMECHECK; --- Done at Primary DB

  We run all these scripts (orders full backup and duplicate) for the night. After the auxiliary DB is in editing mode, there will be new archived logs generated in primary DB, which is the DB auxiliary not aware of. . Even if the archive logs are part of the using PLUS ARCHIVELOG backup script, we are talking about the archive logs generated after the auxiliary DB is mounted.
  
  Question1. How to apply these new archive logs in the auxiliary DB?
  
  Question2. On which mode the auxiliary DB must be when we apply archive logs. Editing or open mode?

  To do this, create a standby database, complete his creation and apply to all the restoring archived log files that were generated during the creation on hold and perform a failover

• question of RMAN backup optimization

  Hello
  
  I met a related issue of RAM and would like to understand the answer:
  
  Configuration of RMAN optimization a backup the value ONE. Which of the following commands will affect this setting?
  
  one) backup Archivelog with ALL or AS options, b) backup Backupset ALL, c) backup Tablespace, d) Backup Database
  
  I think that all of the above are affected by the backup optimization, however, only a, b and d seems correct, not c. I wonder why tablespace is not affected - it is not read-only, etc. ?
  
  Any ideas? Thank you.

  That is right. Please see the link to the doc,

  What I understand:

  'restoration' is the process of restoring a database or backup data file
  'recover' is the process of applying the changes after the time of the backup using redo logs.

  A resetlog is necessary whenever that active recovery logs cannot be used to retrieve the data, or are not synchronized with the controlfile. The resetlogs option creates a new incarnation of the database and reset the counters in the controlfile and redo logs to 0. You lose the ability to perform another CAMILLE or "coherence" of restoration as the active redo logs are not longer in the sequence with the existing backup files. You must make a backup as soon as possible. All data files must be online, otherwise they will become useless after using resetlogs. ALTER database open resetlogs is always necessary during an inconsistent backup, restore using a backup control file (no), or a previous point in time recovery.

  When you use a trace of form of backup control file, oracle updates the control file by reading all the current data file headers, so the redo logs are in line with the data files and recovery logs reset is not needed or wanted. The noresetlogs option is used only when a manual recovery is necessary, for example to cancel the recovery feature by using available log files.

  You mean datafile or data?

  Data can be moved and also you can use cross-platform tablespace option

• Another question quick eclipse

  I use eclipse. in the package exporer, I noticed that one of the projects from my blackberry icon is a folder with a 'J' on this subject; all my other blackberry projects were the icons of the folders with the logo blackberry on top. will this affect the .cod files? If so, how can I activate it in a project of blackberry?

  Eclipse has several icons that could match your description. Navigate to the documentation of the eclipse page, type "icons" in the search box, and then select [JDT icons] in the search results. This is the most likely place to find the exact icon you see and what it means.

  The most likely thing is that your project is set up a Java project, probably because it was created by selecting file > New > project Java instead of the file > New > other, then click BlackBerry project. The easiest way to recover is probably to create a new project and copy all the source files and resource.
