• Best practices for the parameter of ARCH_LAG_TARGET and DBWR CHECKPOINT database

  Hello
  
  Concerning best practices - I need to know - what is recommended or guidelines for these 2 settings of databases.
  
  I found for ARCH_LAG_TARGET, Oracle recommends he set to 1800 seconds (30 minutes)
  
  Maybe someone can guide me with these 2 settings...
  
  See you soon

  Dear unsolaris,

  First of all if you want to follow the full and incremental control points, make the LOG_CHECKPOINT_TO_ALERT TRUE parameter. You will see the checkpoint YVERT and deadlines.

  Full checkpoint is triggered when a log switch occurs and the position of the point of control in the controlfile is written in the data file headers. For just a really little amount of time, the database could be consistent even if it is open and in read/write mode.

  ARCH_LAG_TARGET setting is disabled and the value 0 by default. Here is the definition for this parameter;

  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14237/initparams009.htm

  If you want to set this parameter to the top of the Oracle recommends that it be 1800 as you said. This may subject to change database database and it is better for you to check it out for who suffer.

  Kind regards.

• Best practices for the configuration of HTML5 and native connector at the same time.

  Is it possible to configure the HTML5 and native connector for my users? What would be the best configuration?

  The best way I found to do this is to create 2 web interface sites. one configured for native connector and one for HTML5. I put a URL in the message with a message center as "it is the site of native connector. Click on to HTML 5 ". A similar message with a URL to the site of native connector is on the site of HTML 5.

  I used the above structure at length in many functions and procedures of all associated with an application and works very well. However, I began to review my code and I thought he might be better way to do it. One of the methods I've found is cursor for loop: http://www.techonthenet.com/oracle/loops/cursor_for.php

  and http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/cursor_for_loop_statement.htm#LNPLS1155

  I'm trying to understand the advantages and disadvantages of each method. I get the following (rating my approach is, and cursor for loop is B

  (1) A is faster because it uses in BULK COLLECT IN as opposed to B which is implicitly opens, fetch a row and close each round loop.

  (2) A is a bit messy, a lot more code as opposed to B which is readable, ranger.

  First of all, I would like to know, if my conclusions are correct or not?

  Second, what other differences might be between the two?

  Third, is there another approach, that I'm not aware? Or what improvement could be applied to my approach, if there is?

  Hawk333 wrote:

  Yes, I did. Executable statements are most HTTP POST and PUT request that write in MongoDB on a platform that does not write in BULK. So I have to write one record per HTTP request.

  Then pass PL/SQL to run multipe HTTP put and recorded at the same time. In which case manual removal bulk buys you no performance gain and zero scalability.

  Use DBMS_PARALLEL_EXECUTE to chunk the workload. Execute each thread (parallel work process) using a standard FOR cursor loop (for example for loop in(select...) end of loop; c...) --and inside the loop, make HTTP calls.

• best practices for the storage of the vm and vhd

  no doubt this question has been answered not once... Sorry

  I would like to know the best practice for the storage of the vm and its virtual hard disk to a SAN.

  Any show advantage does make sense to keep them on separate LUNS?

  Thank you.

  It will really depend on the application of the virtual machine - but for most of the applications no problem by storing everything on the same data store

• What is the best practice for a 'regular' Server VMware and VDI environment?

  What is the best practice for a "regular" VMware Server and VDI environment?   A single environment (ESXi and SAN) can accommodate two if it is a whole new configuration?  Or even better to keep separate?

  Enjoying inputs.

  Quick and dirty answer is that "it depends."

  serioulsy, it depends really two things budget and IO.  If you had the money for two without then buy two and don't have to host your server environment and the other for VDI desktop, their IO profiles are completely different.

  If this is not the case, try to keep each type of use for their own dedicated LUN.

• vSpere 5 Networking of best practices for the use of 4 to 1 GB NIC?

  Hello

  I'm looking for a networking of best practices for the use of 4-1 GB NIC with vSphere 5. I know there are a lot of good practice using 10 GB, but our current config does support only 1 GB. I need to include the management, vMotion, Virtual Machine (VM) and iSCSi. If there are others you would recommend, please let me know.

  I found a diagram that resembles what I need, but it's for 10 GB. I think it works...

  (I had this pattern HERE - rights go to Paul Kelly)

  My next question is how much of a traffic load is each object take through the network, percentage wise?

  For example, 'Management' is very small and the only time where it is in use is during the installation of the agent. Then it uses 70%.

  I need the percentage of bandwidth, if possible.

  If anyone out there can help me, that would be so awesome.

  Thank you!

  -Erich

  Without knowing your environment, it would be impossible to give you an idea of the uses of bandwidth.

  That said if you had about 10-15 virtual machines per host with this configuration, you should be fine.

• Best practices for the compression of the image in dps

  Hello! I read up on best practices for the compression of the image in dps and I read the asset from the source of panoramas, sequences of images, Pan and zoom images and audio skins is resampled not downloading. You will need to resize them and compress them before deleting the in your article, because the dps do not do it for you. Hey can do!

  So Im also read as he active source of slideshows, scrolling images, and buttons ARE resampled as PNG images. Does this mean that DPS will compress for you when you build the article? Does this say I shouldn't worth going bother to resize these images at all? I can just pop in 300 DPI files 15 MB used in the print magazine and dps will compress their construction article - and this will have no effect on the size of the file?

  And this is also the case with static background images?

  
  

  Thanks for your help!

  All images are automatically resampled to based on the size of the folio you do. You can put in any image resolution you want, it's not serious.

  On oracle cloud virtual, image I was able to create the database using DBCA (virtual image) oracle cloud. I understand with the virtual image, we won't have a lot of tools like on DAAS cloud. But could please at least use us dbconsole?

• Problem with the virtual copy exports - JPEG vs DNG

  Hi all - just a quick question - I have a set of photos developed in LIghtroom that include several virtual copies of which I now want to export to in the form of final versions on my hard drive. All virtual copies are B & w versions of the masters (post-processing work also differs slightly on the top of the b & w preset).

  I need a patch of JPEG and DNG files.
  Export to JPEG files seems to work without a hitch and all the pictures come out like in Lightroom.
  Exporting DNG however come with a question - all virtual copies come out as images themselves IE. not virtual copies, but they are more b & w as they are supposed to be, but go out like color.

  Color version masters come out well. Exports of virtual copy have different look (as expected) and the file size slightly different (also planned?) suggesting this only thing missing for me is the parameter b & w.

  I have tried everything to fix this problem with no use - export the virtual copies separately etc. As already said - JPEG works, but DNG does not...

  Someone at - he experienced this and if so any suggestions on how to fix...?

  Thks a lot!

  V

  DNG files are 'RAW' files - they cannot be changed.

  You can export only B & W versions as (pixel database files) as JPG or TIFF

  You can export copies of a DNG, but they are still RAW.

  You can embed data in a DNG file (containing similar to XML with the NAVE sidecar files and raw CR2 files), but editing will be visible in software that can interpret the raw data (like Lightroom or ACR)

• What is the interval of time between the virtual machine Linux and ESXi host synchronization?

  I have ESX5.0 with a centos6 installed on this linux virtual machine.

  After the installation of vmware for Linux virtual machine tools, I activated the time synchronization between the virtual machine linux and ESXi host through vmware-toolbox-cmd.

  I wonder what is the interval of time between the virtual machine linux and ESXi host synchronization? If I quickly time OS system, when the OS system time will sync back to the ESXi host?

  According to http://www.vmware.com/files/pdf/techpaper/Timekeeping-In-VirtualMachines.pdf:

  By default, the demon checks the guest only once per minute operating system clock.

  However, depending on whether the guest is behind or in front of the result is different. So, please read the section "periodic synchronization" (at least) in the document mentioned above.
