• What are the 'additional Control Point', 'current log tail' and RBA

  I myself messgae in the alert log file

  Incremental checkpoint up to RBA [0xe.58bfe.0], current log tail at RBA [

  In reading articles on Oracle and the Oracle documents, I have also come across these three terms much

  Incremental checkpoint
  current log tail 
  RBA

  I really want to know what they are in a short and clean definition. Lengthy discussions are devoted to "Incremental Checkpoint" in the url

  Incremental Checkpoint
  http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:19311485023372

  But I got confused.

  There are many different types of control point - the thing they have in common is that they require the database writer to write disk blocks (see the last part of this post: http://jonathanlewis.wordpress.com/2007/04/12/log-file-switch/).

  The "additional control point" is simply the name given to the event of control point which is scheduled to occur every three seconds and allows dbwr to write of disk blocks that have first changed more than a certain distance in the past.

  In this context, RBA means 'redo the address bytes' (address of block redo only sometimes) identify a location to a redo log file.
  The 'end of the newspaper' is the latest ARI redo entry written in the restore log file growth.

  In a control post additional dbwr derives a value for a Resource that represents a previous point in time and written on the disk of the data blocks that have been changed by generated redo before RBA and have not been written to disk since this change.

  Depending on the configuration of your settings file the previous RBA may be derived in a time lag, a volume of roll forward or the number of blocks of data that have to be modified for the IRA at the end of the paper (actually).

  Its the DBWR who will write changed data and that the data file would update the number of control point to reflect the last checkpoint tablespace.

• 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.

• Confusion about restoring controlfile without backup

  Hello
  After you have created a controlfile manually without any backup the database how to a consistent state? Because the newly created controlfile does not have the SNA details as well as information of control point that had the deleted controlfile.
  Also after you restore the controlfile is it necessary to open the database in resetlogs mode? If not why?
  
  Please, help me erase these confusions.

  If the database was SHUTDOWN NORMAL or a cold restore backup (which included of Redo Log files online), the CREATE CONTROLFILE script doesn't have an OPEN RESETLOGS.
  In fact, you can stop after you run the CREATE CONTROLFILE, and with the database is mounted but not OPEN yet, you can query V$ DATAFILE, V$ LOG etc. These points of view in the controlfile are met when the CREATION is made for CREATING had to read the Datafile and Redo Log file headers!

  If it was a hot backup or database required Media Recovery, you should use DATABASE with the HELP of BACKUP CONTROLFILE RECOVERY because the controlfile has no information about backups, SNA etc. which can be used for the review. Therefore, an OPEN RESETLOGS is necessary after the DATABASE to RECOVER.

  Information about backups are never filled in the controlfile as it is not in the database (However, it might be in a catalog (repository) RMAN schema if you have in use).

  Thanks in advance

  * Note * I found the solution... Before I used the system of virtualization and Citrix (XENSERVER) there was little different. That's why I'm stuck on a few easy steps... Well, the problem was that I use 61GB HDD, 5.5 GB of memory. When I create the VM I "ve used the maximum size of HARD drive and left no space for the SWAP file. I used 58 GB, and you have to assume + memory size, this means, 58 GB + 5.5 GB...   So who is right for which I didn't have enough space. Hopefully someone will find it useful. See you soon,.

• Confusion about the requirements for the 2015 CC software

  I currently have Windows 8.0 (64 bit) which is so satisfactory and stable.  I have not upgraded to 8.1 Windows because I can't install same normal updates for Windows 8.0 without experiencing freezes system that only restore points can heal.  So for now, I would stick with what I have.  But the problem is the confusing requirements for various programs within the pile of creative cloud applications:

  Premiere Pro: Microsoft Windows 7 Service Pack 1 (64-bit) or Windows 8 (64-bit)
  Photoshop: Microsoft Windows 7 with Service Pack 1 or Windows 8.1

  Illustrator: Microsoft Windows 7 with Service Pack 1, Windows 8 or 8.1 Windows

  Dreamweaver: Microsoft Windows 7, Windows 8 or 8.1 Windows

  Hearing: Microsoft® Windows® 7 with Service Pack 1 (64-bit), Windows 8 (64-bit) or Windows 8.1 (64-bit)

  So what I'm confused about is the fact that Windows 8.0 is not listed for Photoshop, but Windows 7 and Windows 8.1 are.  Does this mean Photoshop CC 2015 is not compatible with Windows 8?  And that means that Premiere Pro is not compatible with Windows 8.1 since only 7.0 (SP1) and 8.0 are listed, I would have preferred the upgrade of software CC WITHOUT update Windows since I am picky on my installation of Windows 8 stable pipes now solid as a rock.  Fortunately, Illustrator, Dreamweaver, and hearing are compatible with all three, it seems.

• Oracle concepts: Clarity on the control points required

  First of all, I should mention my understanding, and then I'll raise my doubts/queries:
  
  I think I know just enough of what are the points of control and their purpose; in order to validate and to have a deeper understanding, I was going through section "Importance of control points for example recovery ' chapter 'Instance of Oracle database' of ' 11 g Release 2 Oracle® database Concepts'.»
  -Oracle link Docs
  http://docs.Oracle.com/CD/E11882_01/server.112/e25789/startup.htm
  
  Now I need some clarification on the mentioned content there.
  
  I knew that control points are used to ensure that the control file and data files are synchronized and and it is a point where recovery instance is required, doc Oracle he mentions as a control point position.
  
  First question:
  I see many types of checkpoints mentioned here as put on checkpoints, Tablespace and data files checkpoints and additional checkpoints, I tried to get that said, can anyone make it a little clearer to me in simple terms?
  
  Second question:
  In the Oracle RAC environment, there are several threads to redo (one for each instance), how recovery Instance that happens? It is not clear to me, I want to say how serialization between multiple threads to roll forward to retrieve one or more has no instances?
  
  Kind regards

  The term "checkpoint" has changed meaning over time. The original meaning was close to your description - a control point has allowed Oracle to determine that all blocks of data changed before a specific point in time (SNA) was written on the disc - however there are has reasons why Oracle might want to make sure that a specific blocks of data modified subset had been written on the disc and that's why the checkpoint term has expanded to cover the options such as a checkpoint of tablespace, or a checkpoint of object reuse. For example - if you truncate an object, then Oracle must copy everything puts in buffer for just that object on the disk before making the data dictionary and the space of management changes which perform the truncate (where the control point"reuse of objects '").

  Second question:
  In the Oracle RAC environment, there are several threads to redo (one for each instance), how recovery Instance that happens? It is not clear to me, I want to say how serialization between multiple threads to roll forward to retrieve one or more has no instances?

  All active instances in a RAC system will be constantly chatting to each other on the network and via the control lead - as soon as any instance think of another instance has failed, it will try to acquire exclusive global "recovery lock" - on the top of my head, I think it's the lock of the IR. When he arrives this lock, all other cases knows that there is a body controlling a recovery. Indeed the instance that got the blocking takes on the identity of the instance failed to recover through its newspapers online redo - obviously the process are much more complex than that, but it's probably a good starting point for an answer to your question.

• Concepts of control points

  While trying to understand the concepts of control points, I stumbled on the following
  
  "
  TimesTen keeps two files of control point for each database, named
  DataStoreName.ds0 and DataStoreName.ds1. * When a data store is controlled
  on the disc, TimesTen replaces the older of the two files.* checkpoint
  * Only data that has changed since the last checkpoint operation is rewritten in
  the checkpoint file *. The checkpoint operation scans the data store for blocks that
  have changed since the last checkpoint.
  
  "
  
  I have the following queries
  
  (1) I thought initially that TTdb manages 2 copies of the same data, so that if a single file becomes corrupt other can be used when recovering - but after reading the above, I believe that it is not so
  
  (2) the first statement says two CP files older than th is crushed and then immediately the explanations that says only the changed blocks is wirtten to the CP file... I'm very confused now... What recovery will happen in this case, what happens to the existing data?
  
  Pleas explain the above concepts

  The description is poorly written. Each control point image is a complete database image, but they are not the same (since we're still 'new' than the other). When a checkpoint occurs, he writes in the oldest checkpoint file. It does not crush it but rather updates "in place" (by a combination of lseek() and write() operations) to put it in sync with the current state of the database in memory.

  Control points are "blurred", because they do not block queries or operations; so the image of control point isn't 100% of internal consistency, but this is solved using the transaction, as part of the recovery logs, to standardize the reloaded database. A clean shutdown a special type of control (a static checkpoint) is taken, and this image is consistent.

• 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;

  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 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!
