  What are the advantages and disadvantages for the largest and the smallest block size block size?

  Smaller size of block

  Benefits
  Relatively large GoodHas air space due to metadata
  (i.e. block the header).
  Not recommended for the outline. He could only
  be stored for each block, or worse, a few lines line
  If one line does not fit into a block, for small lines with a lot of chance of chaining
  access.
  Reduced block contention.
  Disadvantages
  A relatively large air space due to metadata
  (i.e. block the header).
  Not recommended for the outline. He could only
  be stored for each block, or worse, a few lines line
  If one line does not fit into a block of chaining.

  Larger size of block

  Benefits
  Lower overhead, so there is more
  room to store the data.
  Allowed to read a number of lines in
  the buffer with a single I/o cache
  (according to the size of line and block size).
  Good for very large or sequential access
  lines (for example, LOB data).
  Disadvantages
  Waste of space in the buffer cache, if you
  random access to small lines and have a large block
  size. For example, with a size of 8 KB block and 50
  size byte of the line, you will lose 7 950 bytes in the buffer
  When you make a random access cache.
  Not good for the index used in an OLTP blocks
  environment, as they increase the claim to block
  on the leaves of index blocks.

• What are the size of partition recommended for installing Windows 7 Professional 64-bit?

  What are the size of partition recommended for installing Windows 7 Professional 64-bit? I have a 2 TB internal hard drive and want to install Windows and Norton Internet Security on the drive C, drive D and drive E data programs.

  Thanks for a response.

  Brenda

  Original title: size partition Windows 7 Professional 64 bit

  For technical purposes, I recommend you only keep utilities all programs that you install on the startup disk. This is recommended if you plan to upgrade to future releases of Windows such as Windows 8 because you will experience problems with the installation program.

  I recommend however, you can keep accumulated data such as Documents, Photos, music, videos on a separate partition to ensure custody.

  The recommended size for the boot drive around things like Windows, future growth for applications and the Windows updates and program updates will be considered.

  So I recommend not more than 200 GB, for a lot of space, I would shoot up to 300 if you want to keep things like System Restore Points.

• What are the dimensions of the Pocket-size images and Board Contact?

  Dimensions of the photo images print Windows 7

  No one knows what are the dimensions in the Pocket and the images of the Board-Contact format? I can't crop to fit without knowing what size I have to crop.

  Hi Weaselspoon,

  Dimensions for portfolio would be 2.5 x 3.5 inches.

  Dimensions for photos of the contact sheet should be 2 x 2 inches if you are using the Windows Photo Viewer.

  See picture printing: frequently asked questions to get answers to some common questions about printing in Windows Photo Viewer.

  Hope this information helps.

• What are the best practices for creating only time data types, and not the Date

  Hi gurus,

  We use 12 c DB and we have a requirement to create the column with datatype of time only, if someone please describe what are the best practices for the creation of this.

  I would strongly appreciate ideas and suggestions.

  Kind regards
  Ranjan

  Hello

  How do you intend to use the time?

  If you are going to combine with DATEs or timestamps from a other source, then an INTERVAL DAY TO SECOND or NUMBER may be better.

  Will you need to perform arithmetic operations on time, for example, increase the time to 20%, or take an average?   If so, the NUMBER would be preferable.

  You are just going to display it?  In this case, DAY INTERVAL in SECONDS, DATE or VARCHAR2 would work.

  As Blushadow said, it depends.

• All the members (but 1) are removed from the entity dimension in planning and deployed to essbase. -What are the data deleted in essbase so? / The data can be restored by restoring the entity dimension?

  All the members (but 1) are removed from the entity dimension in planning and deployed to essbase.

  -What are the data deleted in essbase so?

  The data can be restored by restoring the entity dimension? EPMA the entity dimension is still in tact.

  It is unclear what exectly arrived, but looks like a change was made in the dimension entity planning (not EPMA) and then deployed (successfully).

  In essbase, we see that the entity dimension has only one member left for the appropriate plan types, as in the planning.

  If you remove members and then push that yes the essbase data is deleted, if you need back then you will need to go back to your restore process.

  See you soon

  I just increase the disk size of Virtual Machine from 80 GB to 150 GB successfully. The next thing to do is to repartition the disk size of Guest OS Windows Server 2003 in 150 GB.

  What are the specific steps to increase the size of Guest OS Windows Server 2003 disk?

  Thank you.

  Only, I tried start gparted-live - 0.7.0 - 4.ISO both gparted-live - 0.7.0 - 7.iso in VMware Player and had no problem in order to check the MD5SUM.

• What are the consequences of a trigger in peaktime compiling in a data base.

  What are the consequences of a trigger in peaktime compiling in a data base.

  Compilation of a trigger (table), should temporarily be a lock on the table involved.
  Therefore, cannot exist any current transactions involving the table.
  As a trigger is an object of higher level (dba_dependencies - wise), the compilation it does not cancel other objects.

  That said: I would not recommend doing so for peaktime...

• What are the relationships between the logging and IKM?

  What is the best method to use in the following scenario:
  I have about 20 tables with the large amount of data sources.
  I need to create interfaces that join the source tables in target tables.
  The tables are inserted every few seconds with about hundreds of thousands lines.
  There may be a gap of a few seconds between the insertion of different tables that could be attached.
  The source and target tables are on the same Oracle instance and schema.
  I want to understand the role of: 'Logging CDC' and "IKM - incremental" and
  How can I use it in my script?
  In general, what are the relationships between "Logging" and 'IKM '?
  Use both? Or maybe it's better deelte and insert the target tables?
  
  I want to understand what is the role of "Logging CDC"?
  Can 'IKM - incremental' work without "logging"?
  Must 'Logging' have PK on the tables?
  What should I do if I can't say PK (there may be several identical lines)?
  
  Yael thanks in advance

  Hello
  Thanks for your quick response!

  No probs - its still fresh in memory I did a major project on this topic last year (400 tables, millions of lines per day (inserts, updates, deletes), sup-5 minute latency). The problem is it isn't that well written on the web, that you have read the blog of the example I linked to in my first answer? See also here: http://odiexperts.com/changed-data-capture-cdc/

  Always on logging:
  My source table is inserted all the time.
  The interface to join the source table in the target table.

  In ODI, the correct term would be your source table "fits" in the table target, unless you mean literally that want to join the the source with the taget table table? My question if you want to do with the result of the join?

  What exactly the "journaling" CDC updates?
  It updates the model of ODI? interfaces? The source of data in the model of ODI? The target table?

  Logging CDC configures and deploys the data capture mechanism (Triggers or log based capture, IE Logminer/streams/Goldengate) - it is not updated the model as such, she pointed out the metadata of the model of ODI repositoty as a CDC data store, allowing you, the developer say ODI to use log data if you wish (reported in the interface) There is no change in the target table, you get an indicator of metadata (IND_UPD) against a line during the integration (in C$ and I have tables$) that tells you if its insertion (I) and update (U) or deletion (D). It had ' lines allow you to synchronize the deletions, but yoy say its inserts only then you probably used use this option. "
  So the only changes are the source table to your interface, another diary data (if you use logging) or the table of the actual source (if not using the logging).

  This is the main thing that I don't understand!

  I hope I made a little clearer.

  Try the following as a quick test:

  Reverse a source table an engineer and the target (at least) table.
  Import the update incremental LKM and IKM.
  Import of the JKM you want to use.

  Create an interface between the source and the target without any deployed JKM.
  Configure the options of JKM on the model, the "Start log" to start the process of capture - this is quite a complex stage and a lot of things to understand what is happening in the source database, better to check code ODI sends to the database and to review the documentation of Oracle database for a description of what his weight (instantiate Tables (, sets of creating change, creation of subscribers etc. establishment of newspaper groups, creating views Journalising etc.) -you will need to consult your Source DBA database initially as ODI wants to make many changes to the source DB (in mode Archivelog process max, parallelism, size, Java etc.)

  Now, edit your interface and mark the table source for use "Journalized data bank.
  Restart your interface
  Compare the difference in the generated code in the journal of the operator, see the differences of the operator.
