• Difference between 12 c in memory option and 11 g USER_TABLES KEEP

  Can someone enlighten me please in a brief comment on the difference between the new option in memory of Oracle 12 c and the existing functionality in Oracle 11 g, where you can store a table permanently in STORAGE buffers (USER_TABLES KEEP) cache as shown in the code example below?

  I searched on internet for an answer to this, but without success.

  CREATE TABLE t1)

  my_date DATE NOT NULL,

  My_Number NUMBER (12,10) NOT NULL,

  my_row NUMBER (12) NOT NULL)

  STORAGE (USER_TABLES) KEEP;

  Source: Oracle Buffer Pool Keep pool to recycle

  Presentation of Juan Loaiza is probably available on the Oracle now, but in broad terms: the component in the data memory (specified tables - perhaps with a restriction to a subset of columns) in the form of columns in a space dedicated to the SGA. Data are kept up-to-date in real time, but Oracle is not using undo or redo to keep this copy of the data because he never persisted on disk in this form, it has recreated in memory (by a background process) if the instance is restarted. The optimizer can then decide if it would be faster to use a columnar approach or on lines to process a request.

  The intention is to help systems that are mixed OLTP and DSS - which sometimes have many clues 'extra' to optimize the DSS queries that affect the performance of the OLTP updated. With the copy of column in memory you should be able to much "DSS that they ', which improves the OLTP response time - indeed things in memory is behavior a little as non-persistent bitmap indexing.

  Last updated 18 Oct:

  I was reminded that, in my view, that the presentation also included a few comments about how the tire code also left the "vector" (SIMD) instructions to the CPU level allow the code to evaluate predicates on several lines (extracted from the Bank of the column, not the location of the line) at the same time, and which contributes to the high rates of data scanning Oracle Corp. is claiming.

• Find people to KEEP pool

  Hello
  
  recently, a DBA I know has asked to make a list of candidates to KEEP pool in the buffer cache. He is not familiar with the application. Is there a way to do automated, or is - something that only a person familiar with the business logic can do manually?
  
  I googled a little on the subject, but haven't found much, with the exception of Mr. Burleson scripts (which has a history silly advice so I don't him trust) theoretical or general discussions (like the thread on AskTom). I am interested in someone who has made (or learned why this cannot be done) is sharing his experience.
  
  Thanks in advance!
  
  Best regards

  Basically, I don't thnk that you will be able to get lots of benefits on the application, except if you know demand well enough to say:
  

  
  This object is large enough, so randomly accessible we continue rinsing of the memory blocks, and if we kept in memory, we would avoid random disk N bed / hour.
  

  
  Next, you will need to set aside cache much more as there are has blocks in the object (according to the requirements of update and the coherence of reading) and a recycle cache. And you still don't know how much extra I/o other objects would do as a side effect.

  You've probably seen the articles that I wrote on the anomalies with Dungeon - here are some links if not:

• What is the difference between the cookies keep until I close firefox and the history of cookie empty closing firefox?

  In the settings of Firefox 33.0 (I use Ubuntu 14.04, but the functionality is the same for Windows 7) there are two ways to delete cookies when firefox closes. Or at least, there seems to be.

  Is first the cookies keep until firefox is closed

  Second is to check the box for clear history of firefox closing and in the settings check cookies.

  What is the difference between these two options?

  I usually have two configuration but I noticed that a connection was not save for td canada trust EasyWeb, even though I have an exception set for it. Now I unchecked to remove cookies by disabling the history on close and connection records correctly.

  This connection allows to save 7 cookes under easyweb.td.com and 10 cookies under td.com and I have exceptions defined for both. If I clear the history when closing and include cookies, half of the td.com cookies disappeared when I close firefox and re - open. The same is true if I'm not the exception.

  So currently I can't find a way to keep all cookies if I clear the cookie history when firefox closes. What is the difference with this option?

  When you change the default cookie 'to life' of "keep until: they expire" to "keep until the: I close Firefox", Firefox changes all persistent cookies that sites set session cookies. To allow a site to place a persistent cookie, you need to make an exception (site permission).

  When you turn on the story to stop compensation and include cookies, running a completely separate process that doesn't doesn't pay attention to the duration of cookie or exceptions (permissions site). There just nukes all.

  Note that some cookies could survive if they are encoded in the history file of your session of compensation at the stop, a Firefox uses to restore your tabs and windows from last session. I have not tested.

• What is the difference between the CACHE and the PIN code?

  What is the difference between the CACHE and the PIN code?

  Cached, it's when you specify CACHE as part of a CREATE or ALTER an object to say Oracle when the blocks are retrieved this object these blocks should be put to the most recently used end of the LRU (least recently used) list in the buffer cache when a full table scan. Under normal circumstances, when the blocks are retrieved in memory, in that they are placed least recently used end of the LRU list. This means that the data that was most recently viewed typically will remain available in the cache buffers for awhile. Therefore, subsequent runs of the same query should find these blocks already in the buffer cache and not to recover disk again. When you use the CACHE, you say you want to put the blocks retrieved at the end of the list, which means that they will be the first blocks "aged" off the buffer cache when more space is needed.
  A few reasons to use the CACHE are:
  (1) for tables of small (only a few blocks that must be read to retrieve the entire table).
  (2) when you do a select statement returns a huge amount of data, and you do not necessarily have if wait for the query to run any time soon. In both cases, you give Oracle an opportunity to eliminate the blocks quickly to make room for more 'necessary' blocks instead of having to follow in the LRU list.

  Pinning is when you want to keep the objects in memory and to prevent them from being aged by the normal mechanism of the LRU. You use the INVALIDHTOMEH to "pin" PL/SQL code in memory, so that users are not experiencing intermittent slowdowns when code gets years out of the shared pool and must be recharged.

  The bottom line is that caching can blocks be moved quickly while pinning retains the information in memory to avoid the re-loads.

• What is the difference between Foglight JavaEE and Foglight JMX monitoring?

  Hello

  I have a plan to monitor the 6.1.0.17 WebSphere Application Server (32 bit) and 7.0.0.5 (64-bit)

  But I understand not all Foglight for JavaEE and Foglight for JMX.

  Foglight for JavaEE or Foglight for JMX is able to monitor WebSphere?

  What is the difference between Foglight JavaEE and Foglight JMX monitoring?

  Thanks in advance

  Jeans

  Just to add to the excellent answers already posted.

  We have 2 agents which allows you to monitor Java:

  1. a JavaEE agent that runs inside the JAVA virtual machine and the information of both JMX and instrumentation.

  This Agent will give you JMX information like information of JVM (use of the bunch, son etc.), of the Application and server availability information and other information of JMX/PMI (connections pools, pools of ejb, servlets, jsp, JCA and more).

  Java EE & # 039agent also gives you information of the instrumentation - RFA count and response time, exceptional output and timeout information, distribution of queries (App/DB, component technology, server, application failure), object tracking, transaction flow and stransactional between servers and data sources) and ask traces (the ability to see the trees of the RFA at the method level to know where things are slow/stuck).

  2 JMX agent is running outside the JVM but can run on the same computer or on a remote computer, this agent requires access active, JMX. This agent gives you information JVM, availability server/applications, as well as some data as the application server published using JMX (pools of connections, JCA, EJB, servlets, etc.). The JMX agent also gives you the ability to see a list of the mbeans, get the data they expose (javaEE agent gets only a predefined list (same list that is used as a template for the application servers in the JMX agent)).

  Hope this helps

• Difference between these remote VPN

  Hello world

  I am studying for exam CCNP VPN.

  He had to confirm

  1 >SSL tunnel complete with the AnyConnect Client software.

  the user need software on PC to connect and they get the IP address of the DHCP on the SAA pool.

  2 >full tunnel RA IPSEC VPN Client or Anyconnect -.

  Above are remote VPN identical types.

  They look the same to me.

  Need to know there is a difference between them?

  Concerning

  MAhesh

  Hello

  Well it seems to me that one refers to the AnyConnect Client only and this is logical because it specifically referred to the complete SSL Tunnel. AnyConnect is software Cisco SSL VPN Client. The former Client VPN software cannot do this.

  The second mentions just IPsec RA full Tunnel VPN Client and AnyConnect. So it both visit the AnyConnect Client and the old Cisco VPN Client software that both can make IPsec

• Difference between the hosts and virtual machines

  Happy new year!

  I guess that's a stupid question, but I don't know the answer to it.

  I created pools from VM. Some jobs in the pool are hosts and some virtual machines. What is the difference between the hosts and virtual machines. I thought I could only create virtual machines, but I guess I could create hosts as well. -What happened?

  Thanks for your help.

  where does say desktops are hosts?  A host is usually referring to an ESXi server.  A virtual machine is just the guest OS running on the host computer.  A pool is a group of VMs that can extend over several hosts.

  You are mistaken in thinking that they are alternatives.

  EXPLAIN the PLAN meets the PLAN_TABLE.
  Only after that can you use either of
  SELECT... FROM PLAN_TABLE
  or
  SELECT * FROM TABLE (DBMS_XPLAN. DISPLAY);

  Unless you are using DBMS_XPLAN. DISPLAY_CURSOR directly on a present cursor in the shared pool, the PLAN to EXPLAIN is still a sine qua non for DBMS_XPLAN. DISPLAY.

• Difference between webkit and rootkit?

  What is the difference between a webkit and a rootkit?  When I opened Safari a few days ago, I think I should have stopped and opens too quickly because I got a message that it could not open, but I don't remember if she says a webkit or because of a rootkit.  What I've read, a rootkit does not sound good, yet if this was why he was telling me?  A little confused (and have OCD on stuff of security with computers).  Have MBP of 2009 with BONES of Yosemite.  Thank you.

  WebKit is a standard set of libraries to develop and deploy Web applications. In other words, a programmer what to use to get stuff appears correctly in a browser. It is part of an operating system or can not legally be added if desired.

  A rootkit is a set of programs and libraries that criminal substitute Internet savvy can use to take and keep control of your computer, usually without your knowledge or your consent, in order to exploit it for their illegal businesses. As the theft of your identity, money, the data and reputation, use it to do the same for others, etc. He is surreptitiously installed on your computer by the unbelievers when they violate its security components.

• Difference between "Toggle Record" and "toggle / / folder.

  There are two commands different keys that can be assigned to the Publisher of key commands.

  • Enable/disable record (.)

  • / / Record toggle (*)

  

  What is the difference between these two?

  Also, what is the best way to access the logic Pro X 'in the manual of the depth?

  I find that the 'logic of aid' within the program is extremely limited or base. I almost find answers advanced in there and if I ago incomplete or very hard to find.

  Essential difference is that Record/toggle allows you to go in and out of recording mode without changing the mode of playback/record...

  Toggle / / folder

  If the playhead is stopped - rocking record will move you in and out of recording mode (without starting the registration process)

  If the read head moves - rocking record will pass you in and out of recording mode (keeping the playhead moving).

  So the foregoing you pop in and out of recording mode independent of the State of the playhead (i.e. order, reading, record)

  Record

  If the playhead is stopped - by pressing the folder will start recording.

  If the playhead is trying to record - pressing the record won't do anything.

• What is the difference between a version of MAR and the software win7 INKL?

  What is the difference between a version of MAR and the software win7 INKL?

  Hello

  Thanks for posting your query in Microsoft Community.

  • What exactly you're talking about when you say, 'Version INKL of Windows 7?

  I'll be happy to answer your query, however, please explain more about abbreviation INKL. There is a version called Office of ink that is used in the Tablet PC.

  Here's the other version of Windows, you can make reference to:

  MAR - Microsoft Authorized Reacondicionador

  A new PC requires a version of windows with a new key license installed if purchased from a manufacturer.

  A refurbished PC is allowed to use an existing product key (2nd hand if you like) as long as it is always delivered with a certificate of authenticity (COA). This is referred to as MAR (Microsoft authorized Reacondicionador) which means that Microsoft allows to use existing keys/licenses products.

  Buy a version of windows means MAR technically you buy a second hand copy - being however, software, so it comes with COST, will make absolutely no difference at all.

  N and KN editions

  The features in N and KN Editions are the same full versions of their equivalent, but do not include Windows Media Player or other technologies related to Windows Media, such as Windows Media Center and Windows DVD Maker because of the limits set by the European Union and South Korea, respectively. The cost of n and KN Editions are the same as the full versions, as the Media Feature Pack for Windows 7 N and Windows 7 KN can be downloaded for free from Microsoft.

  Generations of VL

  
  VL builds work with VLK (volume license key). Volume license keys can be used to activate multiple installations of the software without a mechanism (for example, a product activation mechanism) controls the total number of facilities. The license for the software is going to impose restrictions on the use of the key. In general, the license will limit the key to a certain number of facilities which must be only the Organization of the licensee and also to place the holder under the obligation to keep a record of the number of facilities, hold confidential and perhaps even require that the holder organization makes available for a software license check check that his use of the key is in the terms of the license.

  Please let us know what exactly are you referring to when you say version INKL of Windows 7, so we can further research and answer.

  Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.
