• How to decrease the disk hard Linux operating system

  Hello everyone!

  
  

  My 4.1 infrastructure

  vCenter

  Cluster with 4 ESXi host

  I installed a VM with OS Linux Centos.

  I attributed a 20 GB of space on its hard drive.

  Virtual machine works ok. But I would like to reduce his hard drive. I want to decrease up to 10 GB.

  I don't know how. Anyone know?

  I think the only way is to use the conversion application with the power - line-machine option
  

  Thank you very much!!

  Jose.

  VMware converter would be the best option with the option of HDD resize at the end another way is affecting your current VMDK THIN and you will be liberated from the unused space.

• Using the loop will decrease performance

  Hello
  Using the loop with a query will decrease performance.
  
  for r_row in (select * from table) Loop
  end of loop.
  
  This is done within another loop for, more cases, it returns a single value.
  It will decrease the performance of the procedure.
  kindly advice...

  Perhaps better understand everything that makes this PL/SQL loop construction.

  PL/SQL is two languages. It's PL (logic programming code) like Pascal, C or Java. You can use a 2nd language in it called SQL. The PL engine will be able to recognize when the 2nd language is used. And it compiles all the things that are necessary for motor PL call the SQL engine, pass the data to the SQL engine and get back data, etc. (compare this with the complexity of the use of SQL in Pascal, C or Java language).

  So what's this loop? The PL engine recognizes the SQL SELECT statement. It creates an implicit cursor by calling the SQL engine to analyze (I hope a soft Parser), then run it.

  As part of the loop of the PL, the PL engine now calls the SQL engine to extract data (lines) of the cursor. With 10g and later, the engine of the PL is smart enough to use the implicit treatment in bulk.

  Before 10 g that he used to extract a line from the SQL engine, make the loop, the next line extraction, the loop, etc. In other words, if there is a 1000 lines to pick up, he'll call the SQL engine after 1000.

  With 10g and later he get a 100 lines, which store in a buffer internal and then make the loop once 100. With a 1000 lines to fetch, it requires 10 extractions in bulk instead of one 1000 rank of extractions.

  These extractions require a change of context - as the engine PL must not out back, and in the SQL engine to extract a line. It is an overhead projector and can become so slow the context switch nothing more.

  And it's the construction of bases for this loop (and most other cursor loops) in PL/SQL.

  The ideal is to reduce the number of context switches. It is an overload that can have an impact on performance.

  What about using a loop in a loop. As 'bad '. This example uses the outer loop to retrieve the data. These data are then used to excite the extraction in internal or nested loop. The outside loop draws data from the SQL engine in PL variables Inside loop drives that same data back to the SQL engine.

  Why? It would have been much faster not to pull and push data between the loops using PL.

  It will be much faster do so only through SQL. Write the two loops as a single SQL statement and have the SQL engine directly driving these loops itself. This is called a JOIN in SQL. And the SQL engine can do not only more quickly, but it has a few algorithms of multiplied can be used which are even faster than a nested loop process (called merge joins, hash joins, etc.).

  Bottom line. Optimize SQL. Reduce to a minimum the PL. *

  Do as much of your data, crunch in SQL as possible. SQL is the fastest 'place' and process the data. No PL (or C/Pascal/Java).

• Add the disk to the PERC H700 of RAID integrated table 5

  Hi all.

  I have currently a Dell PowerEdge R710 configured with 4 SAS - 2 10 146 k Seagate 2.5 "drives in a Perc h700 integrated Bay RAID-5. I ordered a SAS-2 10 146 k disk Seagate 2.5 "to add to the Bay RAID-5 storage, making it a 5-disc set. What is the best way to add the drive to the RAID-5 array without losing any data? I have OpenManage Server Admin on the server.

  OS: Windows Server 2003 R2 32 BIT

  You can use OMSA... go in storage, PERC, virtual disks and select Reconfigure in the drop-down list of tasks available for your RAID 5.  This will add the disk to your RAID 5, then you will need to adjust the partitions in Windows once it is completed.

• "You must format the disk in drive J (k) before you can use it?"

  Hello

  I have a great difficulty to access my external HARD drive. A (Title) error message when I try to connect my HARD drive to pc.

  I have 4 partitions in the disk of which 2 are accessible and 2 are not. Although I have seen some posts regarding this problem already posted, but still nothing has helped me. I tried after restarting the pc, change the name of the drive (from j to o), run the command chkdsk J:/f cmd of switching on the usb ports, but nothing has worked. Except noticed something strange about the file system that is mentioned in RAW instead of NTFS format before the two discs.

  I've attached a screenshot of disk management box, if this can help...

  Thank you!!

  Hey there SimranpreetSingh :)

  I'm sorry for the situation. What is the make and model of drive? Partitions or drives in RAW format are usually those with broken partition tables. For the best chance of getting your data I contact a data recovery company, but bear in mind that their services can be very expensive.

  Some third-party tools are available online, but I can't really recommend a because they are not sure 100%.

  Discs can go in raw if they are not ejected correctly with the safe-eject function. This function checks if all the requests and transfers to and from the reader are completed and that nothing will be lost when you remove the drive. The operating system writes a small amount of data on the disc when he checks everything and then renders the drive secured to eject it. The next time you plug the player into a system, it will try to locate this data element and if it does not find it will recognize the disk as a RAW disk or should be a disc format in order to work with it.

• Low power mode will affect the performance of the camera?

  I take my iPhone 6 on a trip backpack my camera. I intend to put the phone in airplane mode and I wonder if I should also set low power mode. If I put it in low power mode, it will reduce the performance of the camera?

  I suggest that you test this configuration by yourself before you leave.

  You can also consider taking the external battery back up like those manufactured by mophie.

• If I activate 2 processors in msconfig, it will increase the performance of my computer... !

  If I activate 2 processors in msconfig > advanced > number of processors to 2 it will increase the performance of my computer... !

  Original title: two processors

  In most cases, you will probably have to use these options, but they can come in handy. For example, if you think that a startup problem is caused by the presence of more than one processor, you can limit the number of processors used to boot the system by activating the checkbox number of processors, and specifying a number.

  Mr President I'm on hp xw6400 workstation it has 2 processors and I use windows 10 on it, I want to run the two processors at the same time to improve performance is anyway you can tell me how...

  Hello

  Installation is possible, however, the operating system will use a processor at a single time. There are also the prerequisites if you want this kind of installation. Even if it is possible, we have no advice to use both processors at the same time, because performance will always be bottleneck depending on the hardware and the operating system you are using.

  Kind regards.

• I just bought the Nvidia Quadro K5200.  It comes as AE not supported inside.  This will impede the performance or not?

  I guess because it is a new card that has not been tested, but it will not be considered as supported by the software.  My only question is will it impede performance, and if so how should I go that deals with the repair.

  Could this be a problem with third-party plugins that use 3D Raytrace?

  The ray-traced rendering engine is not relevant for third-party plugins. It is not something that they could never use. Engine render raytraced all makes AE was create a 3d geometry in the native space of AE. This has been replaced by the inclusion of Cinema 4 d Lite with your After Effects installation.

  Mylenium says, there is no need for it unless you want to use old AE tool 3d creation. What version of AE are you using? If this is a recent version, there is a box to allow AE to use unsupported cards to speed up the ray-traced rendering engine. Again, it is the only feature that really used and that the function is considered to be dead. Here's what Adobe said on the use of the GPU EI: features GPU (CUDA, OpenGL) in After Effects

• I have 10 items.  I'm trying to update camera raw plug so it will read the first lines of a 7dmarkii shot. I can't find where to put them to update to the latest version of 8.7.  If someone could please point me in the right direction.  Thank you very muc

  Normally, I shoot with the 7dmarki and have never had any problems.  After troubleshooting my error message 'cannot open IMG1111 because it's the wrong file type', only the options have been updated plugin raw from the camera, to buy the latest version or uninstall and reinstall.  First train to the plugin to update because it was a leased device.  Thanks again!

  Thanks MichelBParis!  I didn't see where he said to 12 items.  I downloaded the free DNG Converter last night and not had much luck.  It is not recognizing that I have all files in the folder at all.  Don't know what I'm doing wrong!

• DBMS_STATS.gather_table_stat will affect the performance of the database

  Hi all

  Please notify dbms_stats.gather_table_stat so on to materialize views will monopolize the database performance?

  Hello

  your question is not very accurate, it is not possible to answer more specifically. Collection of statistics requires resources, so it inevitably affects the activities of database performancewise. How it affects the rest of the database, is hard to say without knowing the parameters of the stats gathering work and the number and the size of scanned objects.

  Once statistics are collected their effect is most likely beneficial for the performance, but in some cases the effect can be reversed. This depends on whether or not current performance problems are related or statistical, and whether or not the statistical model Oracle can adequately describe the distribution of the data.

  Stats more important questions can help answer is whether an index can be beneficial for a query. So, if your MV index, then get specific statistics become even more important.

  Best regards

• The CARS performance bottleneck will be the shared disk storage?

  Hi all
  I'm studying CARS and I am concerned about the bottleneck of CARS I/O performance.
  If I have 10 knots and they use the same disk storage to contain the data, then
  they're going to do i/o on the disk at the same time.
  Maybe we got more latency...
  
  Will it be a performance problem?
  
  How RAC does not solve this kind of problem?
  
  Thank you.

  All 10 nodes connected with storage shared by FIBRE cable which give faster latency also all nodes interconnection must be a GIGABIT switch. This option two is going to solve the problem of slow disk i/o.
