The difference between buffer and cache

• Difference between fetch and cache

  Anyone know the difference between recovery and caching when ITS analyses a source? In the document below under Maintenance crawls, it says in step 4 that the robot will pick up the item. This means - it downloads in the memory of the Server HIS?
  
  He also says, in step 5, it compares the checksum of the file that is located in the cache. Is this the same cache is place of conservation for indexed content needs? Any help on this would be greatly appreciated!
  
  Thank you

  Analysis of maintenance
  After the initial analysis, a page of the URL is only ramp and indexed if it has changed since the last scan. The robot determines if it has changed with the HTTP If-Modified-Since header field or the checksum for the page. URL that no longer exist are marked and removed from the index.
  
  To update the modified documents, the robot uses an internal checksum to compare the new Web pages with caching of Web pages. Change of Web pages are cached and marked for re-indexing.
  
  The steps involved in the synchronization of the data are:
  
  1 oracle creates the robot according to the schedule that you specify with the administration tool. The queue of the URL is filled with the URLS of seeds of the source assigned to the schedule.
  2. the robot launches several crawling threads.
  3. each chenille wire removes the following URL in the queue.
  4. Each robot thread retrieves the document from the Web. The page is usually an HTML file containing text and hyperlinks. When the document is not in HTML format, the robot tries to convert the document to HTML before caching.
  5. each chenille wire calculates a checksum for the newly recovered page and compared to the checksum of the cached page. If the checksum is the same, then the page is ignored, and the robot goes to step 3. In the contrary case, the robot will move to the next step.
  6. each chenille wire Scans the document hyperlinks and inserts new links in the queue of the URL. The links that are already in the document table are ignored. (Oracle ITS doesn't follow links binary documents filtered.)
  7. the robot marks the URL as "accepted". The URL is parsed in the future, maintenance tests.
  8. the robot saves the URL in the document table.
  9. If the file system cache is full or the URL queue is empty, the cached Web page stops and commences. Otherwise, the thread of Caterpillar again step 3.

  "This means it downloads in the memory of the Server HIS?"-Yes.

  "He also said to step 5 that it compares the checksum of the file that is located in the cache. Is this the same cache which is the place of conservation for content that is indexed? "- Yes, but I'm sure that the checksum (as calculated to the last time) is stored in a table, so that it is not actually access the cached file.

• What is the difference between objects and units in coherence?

  What is the difference between objects and units in coherence?
  For example, < high-units >

  The units are the number of entries of data stored in the coherence of caches.
  The high-units element corresponds to the maximum number of 'units' (entered data, including units in order to backup, not even with objects) allowing to store in a particular JVM for a specific cache coherence. In addition, this number should be the same on all nodes (i.e. use the same cache on all nodes configuration file).
  The objects are the number of entries of data stored in cache coherence excluding the entries for other purposes (for example, backup).

  RE: To get Coherence to report object sizes you need to set the unit-caculator to binary.
  

  If you don caculator-unit set, consistency can use the default setting (set) to the report.

• What is the difference between AXIEM and EMSIght? What are the benefits of AXIEM by EMSight if any?

  I wonder what are the differences between AXIEM and EMSight. Are associated with application? One is better than the other? Please explain.

  AWR estimated AXIEM most powerful plan EM Simulator around.   AXIEM is at the center of continuous research and improvement, while EMSight is only worked on if revealed serious flaws.  Here is a summary of the differences:

  Mesh

  • EMSight must mesh the nearest grid drivers using rectangles.  This causes the mesh to have more elements mesh when there are small and large geometries.  The grid should be small enough to capture the small geometry but then causes large geometries to mesh more.   In addition, angled or curved structures causes inefficiencies mesh.
  
  
  • AXIEM STS forms, rather than a grid.  In addition, the mesh can be rectangle or triangle.   This allows a much more efficient mesh.   AXIEM generally have a much more efficient
  
  
  • AXIEM contains the ability to process forms to clean geometries that cause inefficiencies of the mesh.  EMSight does not have this feature.
  
  
  • AXIEM can forms thick metal mesh, EMSight can not, and user must make approximations when thick metal will change coupling (loss is recorded properly with the thickness of the metal)

  Ports

  • The ports are for the most part similar, but parasites due on AXIEM ports are less.  In addition, the AXIEM has a side wall, thus the effects of not move of the terms of reference of the edge of the line are a lot less AXIEM in.
  
  
  • Ports can be added to most any place in geometry with AXIEM.  For EMSight, the ports are usually only added outside the geometry and have limitations to the aircraft on either side of the reference speaker.

  Problem solvers

  • EMSight does not have a low frequency Solver.  Stop low-frequency and then extrapolate to DC.  This usually works well, but you must take into account if the extrapolation is accurate.  AXIEM presents both a low and high frequency Solver so will do better in a low frequencies generally much better in DC.
  
  
  • Solver of EMSight scales O (n) ^ 2 for memory and O (n) ^ 3 for the moment.   It has a special algorithm to break the question of memory, but the question of time is the killer.  AXIEM has a direct Solver which scales in the same way and an iterative Solver which will scale O (nlogn).   In other words, AXIEM can solve a lot of bigger problems than EMSight.
  
  
  • Several AXIEM processes are multithreaded as EMSight.

  Speaker

  • EMSight is inside a perfect driver side wall.   This works well if you the circuit is in the same cavity.  If not, you must know the rules of them on to the forms of space of the flanks and how that much to extend the port could reference planes.   AXIEM is not here.   AXIEM does not currently have to simulate a perfect driver side wall.

  I don't know that I missed a few aspects of the tools.   From the point of view of the AWR that AXIEM is the tool of choice, except in a few cases have been EMSight may be required.

  What is the difference between nc6320 and nx6320 laptops?

  Can I use the same drivers for each of them?

  Hello:

  There is not much difference.

  If you want to compare all the details you can check this link:

  http://h18000.www1.HP.com/products/QuickSpecs/12428_div/12428_div.PDF

  You can probably use the same drivers for either, but they all have both their own support pages and separate driver.

• What is the difference between Fdisk and Chkdsk programs?

  Hello:

  I don't think I have a common question of OS knowledge and I worked a lot with both, however for years so I forgot everything I used to know.  I was talking to someone Executibles MS-DOS command line and this person I know told me in email and I did not at the moment, but he said the following:

  "Fdisk and chkdsk are pretty much the same.

  Being an old Microsoft OS Engineer I knew it was wrong, however I've been retired since almost 20 years and I have not worked with either for a while.  I looked in the KB for articles explaining the difference between fdisk and chkdsk or define at least the two against each other, but there is no specific article I could find.  I remember the days when the scariest user had a problem, but they ran all third party software on their computer and have installed BETA version software etc so I'm sure you know the drill and this type of person.

  The person who said this about fdisk and chkdsk is one of those people.  It is a really nice guy, but a nightmare to Microsoft when you talk to a convenience store to the BONE for assistance.  Is there someone out there who could you, please, help me and summarize an irrefutable definition or description indicating the differences between fdisk and chkdisk?  I don't remember the basic functions both I widely used both, but too many years have passed and I don't want to sound like a fool trying to write about the differences.

  I'd appreciate any help I want to educate my friend and the intention is to not make this person feel like a stupid either.

  Thank you, and I expect your response.
