• Basic questions about the PL/SQL web services and data source names

  Hello
  
  I've successfully generated a web service for a procedure from PL/SQL packaged JDeveloper 11.1.1.3.0).
  
  The following code was generated in the base class for web services:
  

   __dataSource = (javax.sql.DataSource) __initCtx.lookup("java:comp/env/jdbc/dbconnectionDS");

  However in the weblogic server, the data source name is jdbc/Gisele for deployment fails in a first time.
  
  What is the recommended procedure to solve this problem? The obvious solution is to manually change the source - that's what I did and it worked fine. However if I re - generate the web service I won't lose my change. Is there a better way to do it?
  
  Another question - in the web.xml file that is generated, there is a resource-ref to the data source. I was hoping that change the data source name it would help, but it didn't work. What is - it used to in this context?
  
  Thank you
  Luis

  I forgot to add, so in case some time later and you want to update the connection to your service details, all you have to do is to add the following entry in your weblogic.xml:
  .
  
  JDBC/ref_name_from_web. XML
  JDBC/new_jndi_name
  
  .
  And in this way, you will not have to change any code level to point your web service to another connection.

• Question about the composition settings and make

  I looked for an answer to my question, but had to ask at resort, sorry, it's pretty basic, but a direct response is needed I think.

  I imported a project in Premiere pro with two layers of still images with movement and applied effects. I work for a few weeks now, with variations on these pictures and had many number of exports of EI through the render queue.

  After you import the compositions of first CC my starting point; composition and other settings of composition parameters are all resolved HDTV 1080 25 but the set resolution in which I unfortunately now has, is defined as 'Half' (960 * 540)... New compositions also sets the default resolution somehow half...

  My question is about my previous exports and subsequently.  Together of the composition to "Half" resolution affect the quality of my compositions exported using the render module? So far, all my renders are 1080 p by default and no 960 * 540. These have been uprezed to 1080 of 960? ... - I have not changed any setting on the resolution in the rendering module - they all came out 1080 after.

  Thank you

  Together of the composition to "Half" resolution affect the quality of my compositions exported using the render module?

  N ° except if you change the settings of default rendering, which is "Best settings" in "current Configuration".

• Basic questions about the port of Vsphere mirror

  I set up a lightweight VM that would deal with inter-VM traffic. To do this, I want to activate the duplication of port between virtual machines.

  
  

  I have ESXi 5.5 Update 1 installed, use the Vsphere (no webclient) client. I see no duplication of port capacity on my Vsphere Client

  

  I have some very basic questions:

  (1) all documentation I've read involving 'Port mirror' is done via web Vsphere client. Vsphere is provided with Vcenter (please, correct me if I'm wrong)

  (2) only functions with "Distributed Virtual Switch", not "switch vSphere Standard" port mirroring. How can I activate "Distributed Virtual Switch"? What products can I download/install and try (suppose I go to the user a license for 60 days)

  (3) exist what API to enable/disable/setup Port mirroring?

  (1) all documentation I've read involving 'Port mirror' is done via web Vsphere client. Vsphere is provided with Vcenter (please, correct me if I'm wrong)

  Because the mirror of port requires a distributed switch, you will need to vCenter Server and once in vCenter Server, you can the vSphere Web Client of the user or the vSphere Client (c# version).

  (2) only functions with "Distributed Virtual Switch", not "switch vSphere Standard" port mirroring. How can I activate "Distributed Virtual Switch"? What products can I download/install and try (suppose I go to the user a license for 60 days)

  You can download the server vCenter Server (60 day trial) and you'll have an Enterprise Plus version for your ESXi host vSphere.

  (3) exist what API to enable/disable/setup Port mirroring?

• Question about the memory consumed and active

  I have esx4.1 on three dl585 running. I have about 100 active vm running, and I have a small question.

  My vm is all 2008 r2 datacenter and I gave them 1 cpu and 4 GB of ram. When I recover a single virtual machine and look at the summary page, I see the bones of memory consumed host 4075 mb and the active guest memory 81 MB operating system. My question is can I reduce the host cunsumed memory to 2 GB without noticing a difference within the virtual machine?

  It looks like you can.   To be absolutely sure that you'd need monitor assets long enough to have a good idea of what the average is and what are the tops.

• Question about the Apple Watch and tattoos

  I think buy a Apple Watch very soon.

  I have a full sleeve (which is where I would like to wear the watch) and I wonder if it will cause problems with readings with the heart monitor since I want to use the Apple Watch for fitness training, mainly.

  I read on the page of the heart rate for the saying of Apple Watch:

  "Permanent or temporary changes to your skin, such as some tattoos, can also impact performance heart rate sensor. Ink, model and the saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings. »

  There are other problems in addition to playback of heart rate on the Apple Watch for inked people that may know you?

  Thanks for your comments just to decide if this watch will really be for me before making this purchase, because I missed one for some time.

  If you are looking for, there was a very long discussion about this in the past, only shortly after the release of the Apple Watch. What I've read, it seems that the heart rate monitor is the only victim when it comes to the watch, since this is the only thing that requires the sensors to work through ink. Not all inks makes a difference, but most don't. The activity of exercise/app also uses the heart rate monitor to determine the rate for the year. You can take the time to go to the nearest Apple Store and try on the Apple Watch and see if the monitor works with your sleeve.

• Question about the roadmap WebWorks and Cordova

  Hi, in the WebWorks Raodmap [1] is the following statement:

  In order to make the promise of HTML5 cross-platform development even more real, we will be leveraging the Apache Cordova open source project as the heart of the WebWorks SDK for BlackBerry 10. This will allow BlackBerry web developers to more seamlessly leverage a much wider array of tools and frameworks being built around the "center of gravity" for mobile web applications.
  

  What exactly is? Cordova will replace the Webworks API?

  [1] https://developer.blackberry.com/html5/downloads/roadmap/

  "To make the promise of cross-platform HTML5 development even more real, we will be relying on the open source Apache Cordova project as the heart of the WebWorks SDK for BlackBerry 10. This will allow BlackBerry web developers to more easily exploit a range much more wide tools and frameworks under construction around the 'centre of gravity' for mobile web applications. »

  We'll disect this declaration and I'll add what I can:

  'we will be relying on the open source Apache Cordova project as the heart of the WebWorks SDK for BlackBerry 10' - this means you can think of the future of WebWorks BB10 as being "built" on top of Cordova. So our API and support for the creation of webviews etc. will be built above the standards defined in the project of Cordova.

  "This will allow BlackBerry web developers to more easily exploit a range much more wide tools and frameworks under construction around the 'centre of gravity' for applications web mobile."-there are currently groups creation tools to work on top of Cordoba; Maybe your favorite editor has already Cordova or PhoneGap support. This will mean that you can use in your development BB10, without worrying about the specific tools BB only.

  At the end of this process should in theory be easier to work with WebWorks.

• Basic questions about the installation of ASM

  I can't find definitive answers to the following. Let me try here. I want to build a server Linux, RDBMS 11.2.0.3, running with the ASM. It's just the prototype server, in our conversion of Oracle 11 g on AIX without ASM on Oracle 11 g on Linux with the ASM.
  
  I have an Oracle VM already running cluster and built a number of virtual machines in models, and everything works fine. Now I am installing DSO, have failed repeatedly. Maybe I'm doing something fundamentally wrong. Here are two questions:
  
  1. is it true that the only (reasonable) to install DSO is to install the product called "grid Infrastructure? As far as I know, the answer is 'yes '. But GI seems to be so much more than ASM, although I don't think I want or need. Is there an easier way to get ASM?
  
  2. the matrix certification swear that grid 11.2.0.3 Infrastructure is certified on Oracle Linux 6. (1) I can still see a lot of posts on OTN and elsewhere on the net that say it is NOT supported and that there are has mant problems in get the installation works, and (2) I have tried to install it on OEL 6 and can't get the installer to finish.

  ASM is a feature of the Oracle Grid infrastructure Installation. So you will need to install IM using ASM.

  There is a GI installation which can be installed and configured in two different directions. For a Cluster or for a standalone.

  This option must be selected during installation.

  The installation of GI for a standalone is called Oracle Restart.

  GI for a Cluster installation is called Oracle Clusterware.

  The two options above have the particularity of the DSO.

  A lot of users here OTN tried installing Grid Infrastructure on RHEL6/OEL6 when it is not certified. Many questions appear.

  When it has been certified by Oracle, it remains several notes on MOS that will help you follow the main steps for a successful installation.

  I think you should use OEL 6, since Oracle Linux 6 has been certified by Oracle Corporation, you have all the support on this product.

  One thing that stands out as being undesirable that recommended going is that you place on the items (using the on() approach) code.  The right approach is to assign instance names to your interactive objects and use them to place all code on the timeline where it is easily visible.  In doing so, you will find just that a lot of code that show you can be modularized in functions that can be shared by different objects rather than having each carrying a load full on his back. You will find that you can pass arguments to shared functions that do the same functions capable of supporting interactions with different objects

  Your call you (press) performs a conditional test useless.  If you change the status to be if (project._currentframe! = 25) you can avoid this.

  In all of your executed appeal of conditional statements, you have a few lines that are repeated in each condition, so they can be moved to the end off the conditional statements.

  Your call to it (release) has the same problem as your call you (press).  Use the _parent target overflow is also an indication that most of the code in this appeal would probably serve you better sitting in the _parent timeline and your button could just call this function

• Basic questions about the Permanent Collections

  I'm learning just on Collections, discover that a Collection preserves all the work I did in the collection. So, I guess that the images of a collection are virtual copies which can be adjusted in the develop Module, with the difference that they appear in the catalogue under the imported original files. I suppose also that a changed image can be locked to prevent other changes, say if another virtual copy should be made.

  I understand that Collections should be protected somehow, for example if I have a collection with images adjusted to look good on the web, and another collection of the same images adjusted to the for look good, using a certain printer.

  Maybe I'll ever need adjust the images for different applications, except outside of Lightroom for applications in the CMYK offset printing. As different settings for the slideshow, Web and print can all be contained in a collection, it would probably be best to use the same images, without changing the images for each output.

  Some of you who have more experience can add thoughts here about how best to use the Collections. My goal is to keep things simple.

  TIA,

  Ken

  Ken-

  Put an image in a Collection made not a virtual copy. Either you have to have VC to reside in a Collection. These distinctions may be among the most important! Can I suggest that run you a few tests with VC in and out of the Collections?

  Best wishes

• Question about the game database and the UNICODE character

  Hello
  
  I have to configure a database for an IBM product where is a requirement:
  "Databases must be created using the UNICODE database and National characters as UTF8 games, AL32UTF8 or AL16UTF16 or."
  
  My current database character is: WE8MSWIN1252. Change the current database character set is not an option, so I have to create a new db for this requirement.
  
  My question is:
  (1) how to ensure that "databases must be created using the UNICODE database"?
  
  (2) to take care of character, I'll use in the database creation script:
  
  "
  create the db1 database...
  ..
  CHARACTER SET US7ASCII
  NATIONAL CHARACTER SET AL16UTF16
  .."
  who will take care of him?

  create the db1 database...

• Newbie question about the firmware loading and music

  Hi all.  Firstly a bit of background.  I am a former admin of system IT I got a C240 as a gift.  I tried to remove the music from Windows Vista section of the computer where the C240 is listed as a portable device.  Now, I can't get things to work quite right.  I seem to have the 8 original songs/5 albums that come with the device.  The number has doubled to 16, and half of them cannot play.  I'm not sure I want to do with this device, but I want to clear in addition to all the current music and load my own.  I tried to download the update of the firmware and it still just waiting and never took the screen "search for updates".

  Also, I have Media Player 11 and it does not recognize the unit.  So, how do Media Player to see the device, copy music to it and delete the prepackaged songs accompanying?  Any help will be appreciated.  I don't want to choose the format from the settings menu, unless it's the way to go.  Arrest me please make any more mistakes!  Thanks in advance for help a dummie MP3!  -Victor

  OK I got when I hit reset I changed the USB to MSC settings to automatic detection.  So I reset on MSC.  Now I see the Unit 11 MP so how can I delete and add music?  Thanks for bearing with me! -Victor

• A very basic question about the shared storage

  To implement GR 11, 2 in Sun SPARC 5.10, our sys admins have allocated block devices in the shared storage and they sent us a letter mentioning the disks. This is what looks like their mail
  
  Storage attached with the Node1
  

  /dev/rdsk/c4ikdzs3
  /dev/rdsk/c4ikdzs4
  .
  .

  Storage attached to Node2
  

  /dev/rdsk/c5ikdzj2
  /dev/rdsk/c5ikdzj5
  .
  .

  When I connect with the Node1: / dev/rdsk, I see

  /dev/rdsk/c4ikdzs3
  /dev/rdsk/c4ikdzs4
  .
  .

  as they have said. Same for Node2
  
  
  But all raw devices mentioned above should be visible at/dev/rdsk of nodes. Right? Isn't that whole point of CARS; Shared storage ?

  resistanceIsFruitful wrote:

  Not exactly, if you are referring to the names of devices...

  Each core will make a discovery to support when starting. When dealing with the LUN through one HBA (or similar), there is absolutely no guarantee that the nuclei will detect the LUNS in the same order and assign the same scsi device names to them. A LUN can be called device-foo-1 on a single server and device-foo-21 on another.

  In addition, several HBAs will be dual port and dual fiber running channels. So, not only is the same logic unit seen as a scsi device, different number of each core but you can see more than once. Device-foo-1 and device-foo-33 may be the same physical LUN on server 1.

  To solve this logical device name is required. This will be the name of the same device on all servers - and that it will support multiple paths of I/O to the LUN in turn seamlessly. This is done by looking at the unique signature of the SCSI - called WWID or World Wide nameof the software "special driver. With this unique signature, s/w only recognizes a specific LUN, regardless of what server s/w runs on.

  This s/w is called Multipath on Linux, EMC Powerpath and so on. I expect that you will have something similar on your servers.

  Scsi device that is mapped by the kernel to the unit number logic is not used. In the case of multipath , for example, use the + / dev/mpath/mpath+ devices. In the case of Powerpath, these will be + / dev/emcpower+ devices.

  What are the names of device you will use to 11g Grid Infrastructure and Oracle ASM and RAC installation and configuration of shared storage.

• Basic question about the selection of the AP and multiple channels

  I have about 10 PA (Aironet 1240 G) intended to be deployed one of my floors of office. We examined a diagram of the floor and made sure that we ordered enough to completely saturate the ground with wireless coverage. There are a few AP which are probably only 50' with each other. It's actually a bit exaggerated.

  I put a base on the switch configuration so that there are two different SSID on the access point (one for a production of WLAN and the other for a WLAN comments). Each SSID is associated with a VLAN different.

  I want to know is this what to do on the channels for the AP? Each access point will be independently configured and controlled.

  I understand that there is a way to control which channels each AP uses, but I'm not familiar with the controls or best practices for the configuration of the AP

  Can I do something like make sure that each access point uses a different channel than its nearest adjacent neighbors? Someone would mind sharing what is the command to do it, and where it is applied?

  I have read through some archives and saw people talk to set "no bunk channels" and to configure them to use 1,6,11 channels. I guess I don't understand what is meant by there.

  Manually define you an access point to channel 1, then set his neighbour to use 6 and another neighbor to use 11, and then you who stay?

  What is the worst of the scenarios on what happens when you have no AP too close to the other located on the same channel?

  It is a pleasure to read through the documentation if someone wouldn't mind pointing me to it. I'm still trying to understand the concept, and then I should be able to understand the documentation that came with the AP.

  Thank you for your help.

  If your stand-alone Access Points. If it was a deployment of Comptrollership, in fact to dynamically manage the channels for you.

  But what you really want to do, is you see APs do something like this:

  (imagine each number represents an access point, and it channel)

  1 6 11 1

  6 11 1 6

  11 1 6 11

  1 6 11 1

  It is a conceerne configuration guide. I think he has a small section on the channel assignment. If you do this manually, I think that you specify the actual frequency used in the CLI instead of the channel number.

  http://www.Cisco.com/en/us/docs/wireless/access_point/12.4_3g_JA/configuration/guide/s43rf.html

  So the CLI under the Dot11Radio0 you would do something like 'channel 2412' for channel 1... 2437 for 6, 2462

  for 11...

  If you have APs side by side on the same channel, you are likely to have clients interfere between them.
