• Accessibility of the previous backup Image of RMAN copy after roll forward with the additional days

  Hi all

  I have these 2 questions related to RMAN Image backups. Please suggest the best approaches...

  We are in publishing Standard of Oracle 11.2.0.3 database on instances of RAC ASM on Windows 2008 and want to see the feasibility of using Copies of RMAN images for our databases.

  Have a question about the availability of backups for restoration in a scenario explained below:

  1ST QUARTER)

  To get copies of the Image which are rolled to the next incremental backup. Can we still restore/recovery to earlier date than the Image backup before rolls? If not, please suggest

  What is the best way to accomplish this task if we choose RMAN COPY of IMAGE as our backup strategy.

  Example:

  Log archiving is enabled.

  Sunday evening: full level 0 backup copy Image

  Monday night: 1) level 1 incremental Image copy backup and Roll-forward/apply the incremental backup for the full backup from Sunday

  (2) backup of files to archive log after the full backup from Sunday.

  Tuesday evening: 1) level 1 incremental Image copy backup and Roll-forward/apply the incremental backup for roll Monday transferred (full) backup.

  (2) backup of files to archive log after incremental backup from Monday.

  Wednesday evening: 1) level 1 incremental Image copy backup and Roll-forward/apply the incremental backup to roll Tuesday transferred (full) backup.

  (2) backup of files to archive log after incremental backup on Tuesday.

  Can we restore and recover the data until Tuesday morning 11:00 even if our full backups are rolled transferred by the application of incremental backups. Please suggest

  What is the best way to accomplish this task if we choose RMAN COPY of IMAGE as our backup strategy.

  Q2)

  Q2.a) Scenario 2: with above politics of backup in the 1st quarter.

  If I intend to use the copy of current Image backup on WEDNESDAY NIGHT for the recovery and restoration on-site. understand that

  We're losing backup of forwded for the roll of Wednesday night. Is it possible to take a backup/backup copy of this Wednesday night before being used for on-site recovery, so that we can use it

  for all future restorations.

  Q2.b)

  If we are unable to take backup of the night't Wednesday backup before being used for the recovery on the spot. We can always access backup Image roll passed Tuesday night? If so, can

  I take a new incremental Image copy backup Thursday night and roll forward/apply to copy backup Image Tuesday night. Please suggest the best approach to have accessible backups for each night?

  Thank you

  Hello

  I suggest that postpone differentials apply for a week as says Hemant.

  for example:

  grab the copy of database with tag = "incremental_update" until ' SYSDATE-7 "; ". "

  1 extra strength to recover from backup with tag = "incremental_update" database;

• Commit & roll forward

  Leave for a day

  Querying the table after a day.

  According to Arup nanda blog

  http://Arup.blogspot.in/2010/12/100-things-you-probably-didn ' t - know.html

  We will see the updated record if transaction not committed.

  Redo log won't marker validation, so during recovery, roll forward coming.

  What happens after 2 days if I bounce the DB?

  Redolog have been archived.

  Roll forward is still happening?

  Oracle is also the newspapers archived when starting?

But after time t2 here arrive checkpoint (or switching of newspaper) then the State of the last data block (B) actually in the data file must therefore not redo recovery of this transaction.

• Roll forward standby database with the incremental backup, when a data file is deleted in primary education

  Hello

  I'm nologging operations + deleting some files in the primary and you want to roll forward the day before using the incremental backup Yvert.

  I do in particular, as the files are dropped?

  I got to meet ( Doc ID 1531031.1 ) which explains how to roll forward when a data file is added.

  If I follow the same steps, to make the move to restore the data file newly added, will it work in my case?

  Can someone please clarify?

  I was wondering if reocover noredo is performed before restored controlfile, oracle will apply the incremental backup error-free files, and in this case, what would be the status of the data file in the control file.

  Why do you consider to retrieve the day before first and then in the restaurant of the controlfile will lead to problems. Please read my first post on this thread - I had clearly mentioned that you would not face problems if you go with the method of deployment.

• Confused about "additional control Points.

  Hello

  I'm confused about this sentence from database Concepts 11g Release 2 (11.2)

  Additional control points

  An additional control point is a type of thread control point in part intended to avoid writing a large number of blocks online redo log switches. DBWn checks at least every three seconds to determine if he has to do. When DBWn written stamps Sales, it advances the position of the control point, causing CKPT write the position of the control point to the file control, but not for data file headers.

  I thought that a checkpoint is written datafileheader and controlfile, this happens for example after a switch logfile - right?

  So, why not in the case of additional control point? For best performance?

  Additional control points to reduce the time to recover, as more data is committed to the files of data, right?

  Concerning
  Christian

  There are many types of control points. One that will be updated on the headers of data files would be a complete control and would be applicable to the entire base. The additional control point is induced to keep on enhanching a counter that would ensure that only certain limited stamp Sales would be recovering. That's why a moment of the additional control point, data file headers are not being updated. Control file is probably updated with a "pointer to disk" which mentions the point up to which the dirty buffers are written in files (from the buffer cache) data and where to start the recovery, if necessary. Log file switch will cause a thread control point which, for one instance, would be considered a Global checkpoint only. The additional control point would be for various other reasons such as setting a value for the parameter Fast_Start_Mttr_Target etc.

• Confusion about the size of the array in Oracle 11 g

  There is confusion about the size of a table. When exporting schema 'CRESTELWOMPRD601', the log file shows:

  _____________________________________________________________________________________

  . . exported "CRESTELWOMPRD601." "' TBLRSUBSCRIBERFIELDWORK ' lines of 12.62 GB 35568

  ____________________________________________________________________________________

  which may involve the size of the TBLRSUBSCRIBERFIELDWORK table is 12.62 GB.

  But when I find the size of the table using the query:

  SELECT nom_segment, BYTES / 1024 / 1024 "SIZE (MB)" FROM dba_segments where owner = 'CRESTELWOMPRD601' and nom_segment = 'TBLRSUBSCRIBERFIELDWORK. '

  He said that the size is only 9 MB for the TBLRSUBSCRIBERFIELDWORK table.

  I hope that my request is clear that there is no clarity on the size of the TBLRSUBSCRIBERFIELDWORK table.

  Please get back with the answer to my query

  
  

  Concerning

  Dba_segments indicates the space allocated to the segment while expdp indicates the size of the exported data, so if you had a table with a measure of 1 MB, but no data, dba_segments would 1 MB and expdp would report 0 bytes.

• Confused about trandata

  Hi all

  11.2.0.1

  I'm confused about additional logging.

  I have golden gate replication, but in primary db.

  Is this related to archive the recording? It works even if I'm not on the archive log?

  Installing Oracle: orcl

  Enable supplemental logging (required on primary database only)

  SQL > alter database adds additional log data;

  
  

  
  

  Hello

  One of the main reasons to enable additional logging is to generate logs for the update statement. As insert and remove implies the change to an entire line (addition or deletion of a complete line) and all the columns it while updating can occur on a column of a row.

  Additional logging on the side of database source to some of the columns are very well required to ensure that these changes to the columns that are supplemental logging enabled will be applied with success in the target database. With the help of these additional columns, oracle decides the lines that need to be updated on the destination side. This is so the extra logging is more imperative for replication.

  Furthermore, I try to access the database via sqlplus, I get ORA-00257 (http://ora-00257.ora-code.com/) that mentions
  
  "The most likely cause of this message, it is that the destination device is out of space to store the redo log file.
  
  Now is it possible that an Oracle RAC is unrecoverable, simply because he can't write newspapers? And as we cannot access, we cannot remove these logs?
  
  Help, please

  920550 wrote:

  No, it is the opposite: Oracle instance blocked any new database entry to be recoverable.

  And as we cannot access, we cannot remove these logs?

  Even if archive destination is stored in ASM you can access (for example with the utility asmcmd command line interface).

  What you need to do is:
  1 backup archived redo logs
  2. Remove archived redo logs that have been saved.

  For example if you use RMAN, you can try

  backup archivelog all delete input;

• 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.

  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;

  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.

• Confused about the extension of the Sprite class

  Howdy-

  I learn programming with object oriented ActionScript and am confused about the class Sprite and OO in general.

  My understanding is that the Sprite class allows you to group a set of objects that you can manipulate all the objects at the same time.

  I explored the Open Flash Chart code and note that the main class extends the Sprite class:

  Base/public class extends Sprite {}

  What this lets you do?

  Also, on a related note, how to draw, say, a line once I extended?

  Without extend Sprite I could write:

  var graphContainer:Sprite = new Sprite();

  var newLine:Graphics = graphContainer.graphics;

  ...

  And it works very well. Once I have extend the Sprite class, I'm lost. How can I modify this code so that it still draws a line? I tried:

  var newLine:Graphics = this.graphics;

  My understanding is that since I extend the Sprite class, I should still be able to call its method chart (or property? I have no idea). But, he screams at me, saying "1046: Type was not found or is not a constant of compilation: graphs.»

  A number of things.

  First of all, I would not use this approach in your table constructor. Setting the width and height only makes sense if you adjust the width and height of the existing content, and the table (Sprite) does not at this time here. If you want to give the table a 'size', you could do it like this:

  public function Chart (width: Number, height: Number) {}
  This.Width = width;
  This.Height = height;
  put in a background invisible to this size:
  this.graphics.beginFill (0,0);
  this.graphics.drawRect (0,0,width,height);
  }

  There are other ways, including putting in a form or a Sprite of child as a child for the background so that clear will not erase the background of the chart. This way you could have properties for the background in your table class and update the background as a child DisplayObject instance... a few ideas to think to...

  Then, after that, your chart should be functional...

  Then back in your scenario, you could do this:

  import graphics. Table;

  Stop()

  var myNewChart:Chart = new Chart (300,200)
  myNewChart.render ();
  addChild (myNewChart)

  Hi Muhammad,

  PLS, forget what I wrote before. Which is incorrect.

  Here's the explanation: If you look at the notes 798458.1 Incorrect calculation of Usable_file_mb and the documentation, you will find the following:

  "REQUIRED_MIRROR_FREE_MB indicates the amount of space that must be available in a disk group to restore full redundancy after worse failure that can be tolerated by the disk group."

  Unfortunately, the worst case in your 2 scenarios are defferent (many different):

  If you have 6 disks in 3 FGs is the worst failure
  -failure of a whole failgroup (ca. 1.420 + 1,420 GB) +.
  -failure of a disk in one of the 2 survivors starts (another approx. 1.2 GB, what is the result after the DG survining re-mirroring - you can see who is 1127 which corresponds to the number after you deletet a FG).

  In your other case, where you have only 4 discs 2 FG then the worst failure (to always maintain normal redundancy) is the failure of 1 drive:
  -Failure of a disk with data containing a maximum of 2047 (since it is the size of the disk).

  Hope he says.

• Confused about Directx 9 .0c

  I installed Mass Effect for PC yesterday on my Windows 7 PC.

  After the installation is complete, a popup opened asking me if I wanted to install Directx 9 .0c, as it was required for the game to run. I chose not to install it while I'm confused about Directx backward compatibility.

  First of all, is the Setup installation Mass Effect offers, the same as the Execution on the site of Microsoft Directx end user?

  Second, if the version of the installer from Mass Effect differs from Microsoft, I'm sure the Microsoft runtime more.

  But I do not understand what the runtime needs to reach - it allows me to play the old Directx 9 .0c and previous games on my Windows 7 PC, but still be capable of Directx 10 and Directx 11 games as well?

  One last thing - the Mass Effect system requirements say that my sound card must be compatible Directx 9 compatible .0c. How will I know that my sound card is compatible? I ran dxdiag but he didn't tell me whether or not my sound card is compatible.

  Thanks for your help!

  Hello bingiton.

  In short: install it.

  DirectX 9 is separated to DX10 and 11.  And some games require DX9 optional components that they want installed. Paul Smith - MVP for Windows desktop experience... I crawled off NNTP - for now.

• Confused about the notion of VLAN

  I'm confused about the VLAN. I thought that the notion of VLAN was this computer on different VLANS were not suppose to be able to communicate with each other. I am setting up a 6248 and for me to get DHCP to work, I need to enable ip Routing. When I turn the routing ip, all computers on different VLANS are able to ping each other. Is - it the way it was suppose to work, or am I missing something?
  MGMT is on vlan 4093
  DHCP is on VLAN 100 trunk e34 10.10.1.1
  Host 1 is on VLAN 200 trunk e34 10.10.2.1
  Host 2 is on VLAN 300 trunk e34 10.10.3.1
  active IP routing
  
  

• BlackBerry smartphones, I am new and confused about things 'connection '.

  I am a new BlackBerry - I have a Curve 8320, I am a small business owner, and I'm not connected to a BES. I use the BB Desktop Manager to synchronize with Outlook and to back up my BB and I did pretty well on most things, but I have still a few things that I leave me puzzled. In this forum, I will ask my "questions of confusion" about data options.

  I have a data plan "pay as you go" with AT & T, my provider, because there is practically no cell reception at home where I work. (I not use my BB for email since I was at my computer most of the time). I have a home network set in place and I have incorporated a router that supports wireless. I have connected a netbook to the wireless network and used to surf the Internet, so I know that my wireless connection works. I also managed to create a wireless connection on my BB to this network and on the home screen, it appears the name of my wireless network when I am here at home, so, I know that the device is connected to my network.

  BUT I don't think that I'm really using my home wireless network... I tried the other day browsing the Internet, and then AT & T told me that I hired data charges - I thought that I should not have if I wasn't using their network. Either I am wrong all assuming that they don't charge me if I use my network or I have something set up properly on my BB... someone can provide some guidance?

  Then, I don't really understand what BIS... I searched through the KB and couldn't find something that sets actually BIS... could someone please explain what BIS?

  Finally, can someone please explain the difference between "mobile network" and "wi - fi"? Apparently, if I disable "mobile network" I have no connection at all, including wi - fi. Is that the way things should be? But, I can turn off wi - fi and always get a connection (if I go out too far from my house, South possible and face).

  Thank you... and now I'm leaving the Forum of BB Desktop Manager to ask some questions here!

  Thanks to all who responded... I now have a much better understanding of the work of the whole thing "data". I disabled my LAN connection, which should avoid all charges. The part that confuses me the most, is that AT & T said would not have to pay to use my own wi - fi, but... it doesn't seem to be the case. So, McDonald's and Starbucks will work very well for me.
