A question about RMAN on 11.2

• 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.

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  Oracle will ensure these settings before you mark whatever it is obsolete.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

  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.

  can data be copied to a db tell another db say B, if A is running on Windows 32 bit OS and db B is on Solaris 64 bit
  
  can I have a primary on 10.2.0.4 and physical database pending for this db on 11g?
  
  I know RMAN can exclude tablespace but can we exclude tables as in dataguard table_name %... I know that we cannot just simply wanted to confirm
  
  Can I restore a specific tablespace of PROD to test?
  
  I passed TEST db and have added PROD and additional data files, how to change TEST without recreating the entire db

  can data be copied to a db tell another db say B, if A is running on Windows 32 bit OS and db B is on Solaris 64 bit

  You mean datafile or data?

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

  can I have a primary on 10.2.0.4 and physical database pending for this db on 11g?

  NO.

• confusion about rman restore

  Hello world
  I have some confusion about rman restore and recover procedures. I read doc available in this regard and google as well. A few more questions unanswered in my mind.
  1. do the restore backup command restore controlfile also alongwith datafiles.
  2 database is running in noarchivelog mode. Suppose one of say users.dbf data files has been removed. control files intact. the same seq # is available since the last log backup. Now to restore the database, I use the following steps.
  1 rman > shutdown immediate
  2 rman > startup mount
  3 rman > restore database
  4 rman > restore database
  5 rman > alter database open;
  
  I'm wrong. This is the one. In this scenario, the steps above can be used.
  
  3. even when logseq is not available when the database is saved, I take the following steps.
  1 rman > startup nomount;
  2 rman > restore controlfile autobackup.
  3 rman > change the editing of the database;
  4 rman > restore database;
  5 rman > recover noredo db;
  6 rman > alter database open resetlogs;
  It is a right. can I adopt this procedure in my scenario.
  
  Please do not give all the links I want some explanation of your minds.

  If after the last COLD backup is there not get command of newspaper (this means journal seq number is the same), so you can restore your database since the last backup and can retrieve it. And if thi does not need perform full restoration/recovery. At instead step 3 with DATA RESTORE (or RESTORE TABLESPACE USERS) file and step 4 instead with RECOVER DATAFILE (or RECOVER TABLESPACE USERS) and after that you can open the database by using ALTER DATABASE OPEN. If you have lost datafile users.dbf it means that this (tablespace) datafie has been automatically disconnected.

  3. even when logseq is not available when the database is saved, I take the following steps.
  1 rman > startup nomount;
  2 rman > restore controlfile autobackup.
  3.RMAN > change the editing of the database;
  4 rman > restore database;
  5 rman > recover noredo db;
  6 rman > alter database open resetlogs;
  It is a right. can I adopt this procedure in my scenario.

  Yes you are right in this case. There, you have to restore/recovery complete database, because of your database running in NOARCHIVELOG mode. But after database restore (step4) you can just issue RESTORE database and can open with RESETLOGS options also. Also if you have incremental backups can run NOARCHIVELOG mode even RETRIEVE the NOREDO of DATABASE then you can open the database.

• Many questions about the HP 50 g

  I just ordered a HP 50 g graphic calculator! I have a few questions about this so hang on tight! What is the USB connector on the calculator? Mini-USB, micro USB, or is it a connector owner, "custom". Then, it would be possible to connect a keyboard to the HP 50 g by using the USB Port? Is there a program that would make this possible? (I doubt it would work if you plug it..) I have a Mini-USB to female USB 2.0 connector. So I could just plug the keyboard right, provided that the port on the calculator is a Mini-USB Port. If this is not so that I could use my female to female USB adaptor to connect the keyboard.

• A few quick questions about the Satellite P300 - 18 M

  Hello

  I am about to order a Satellite P300 - 18 M and have just a few questions about this:

  (Although these may apply for other similar Satellite/Equium P300.)

  Is the touchpad made by / to use the Alps or Synaptics driver?

  It has the Wireless N network card, is the map made by Intel or Realtec?

  And also, someone has experience with face recognition software to connect?

  If so, does it take a lot of time to initalise?

  Thanks in advance,
  Jack

  Hello

  The P300 - 18M belongs to the PSPCCE series.
  It uses the two touchpad drivers. Synaptics & Alps Electric
  There is an Intel 802.11agn minicards WLan installed

  The face recognition is a nice tool but local to be illuminated and you must take your face the right of the post sometimes it of not very easy

  But if you face is recognized correctly that the connection should work properly

  See you soon

• A few questions about the difference between the Satellite P70, L70, S70

  Hello, I have a lot of questions about the P70, L70, S70 series that come with a 1920 x 1080 panel.

  (1) what are the differences between the L70 and S70 series? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

  (2) P70, L70, S70 doesn't support a 2nd HARD drive or it's just the P70 series that support?

  (3) all the three (P70, L70, S70 series) come with the same TFT panels?

  (4) of the above series, which supports mSata?

  (5) all the model of each series are delivered with support from mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?

  (6) all the foregoing, are delivered with a S - ATA II or III S - ATA interface?

  (7) who is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.

  Thank you in advance.

  > (1) what are the differences between the series L70 and S70? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

  What models Sat L70 and S70 do you mean exactly? There are different L70-xxx-xxx and S70 models on the market that supports different hardware specifications.

  (> S70 2) P70, L70, support a 2nd drive HARD or is - it just the series P70 that support?
  As you can see in this [Sam P70 HDD replacement document, | http://aps2.toshiba-tro.de/kb0/CRU3903II0000R01.htm] the P70 series supports the 2nd drive Bay HARD, BUT even if there is a 2nd HARD drive Bay, this does not mean that you can use the 2nd HARD drive. In the case where the 2nd HARD drive Bay are equipped with HARD drive connector, you can use the 2nd HARD drive

  I also found the [Sam L70/S70 HDD replacement | http://aps2.toshiba-tro.de/kb0/CRU3703HG0000R01.htm] the document on the Toshiba page and there I see this 2nd HARD drive Bay is not available

  (> 3) all three (P70, L70, S70 series) come with the same TFT panels?
  See point 1). Different P70, L70, S70 models were equipped with different material parts.

  (> 4) of the series above, which takes in charge mSata?
  As far as I know that some P70 models are equipped with an mSATA SSD of 256 GB.

  (> 5) do all the model of each series are delivered with support mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?
  See point 4) not all models supports the same hardware specifications

  (> 6) all of the above, come with a S - ATA II or III S - ATA interface?
  I don t think that SATA III is supported. I guess it would be SATA II

  (> 7) which is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.
  Not easy to answer because there are too many models released in Europea.
  And not all models are available in each country. So I guess you will have to look for the models that have been released in your country.
