• A question about the analytical function used with the GROUP BY clause in SHORT

  Hi all
  
  I created the following table named myenterprise
  

  CITY       STOREID    MONTH_NAME TOTAL_SALES            
  ---------- ---------- ---------- ---------------------- 
  paris      id1        January    1000                   
  paris      id1        March      7000                   
  paris      id1        April      2000                   
  paris      id2        November   2000                   
  paris      id3        January    5000                   
  london     id4        Janaury    3000                   
  london     id4        August     6000                   
  london     id5        September  500                    
  london     id5        November   1000

  If I want to find which is the total sales by city? I'll run the following query

  SELECT city, SUM(total_sales) AS TOTAL_SALES_PER_CITY
  FROM myenterprise
  GROUP BY city
  ORDER BY city, TOTAL_SALES_PER_CITY;

  that works very well and produces the expected result, i.e.

  CITY       TOTAL_SALES_PER_CITY   
  ---------- ---------------------- 
  london     10500                  
  paris      17000            

  Now in one of my books SQL (Mastering Oracle SQL) I found another method by using the SUM, but this time as an analytic function. Here's what the method of the book suggests as an alternative to the problem:

  SELECT city, 
         SUM(SUM(total_sales)) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY
  FROM myenterprise
  GROUP BY city
  ORDER BY city, TOTAL_SALES_PER_CITY;

  I know that the analytic functions are executed after the GROUP BY clause has been transformed completely and Unlike regular aggregate functions, they return their result for each line belonging to the partitions specified in the partition clause (if there is a defined partition clause).
  
  Now my problem is that I do not understand what we have to use two functions SUM? If we only use one only, i.e.

  SELECT city, 
         SUM(total_sales) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY
  FROM myenterprise
  GROUP BY city
  ORDER BY city, TOTAL_SALES_PER_CITY;

  This generates the following error:

  Error starting at line 2 in command:
  SELECT city, 
         SUM(total_sales) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY
  FROM myenterprise
  GROUP BY city
  ORDER BY city, TOTAL_SALES_PER_CITY
  Error at Command Line:2 Column:11
  Error report:
  SQL Error: ORA-00979: not a GROUP BY expression
  00979. 00000 -  "not a GROUP BY expression"
  *Cause:    
  *Action:

  The error is generated for the line 2 column 11 which is, for the expression SUM (total_sales), well it's true that total_sales does not appear in the GROUP BY clause, but this should not be a problem, it has been used in an analytical function, so it is evaluated after the GROUP BY clause.
  
  So here's my question:
  
  Why use SUM (SUM (total_sales)) instead of SUM (total_sales)?
  
  
  Thanks in advance!
  :)
  
  
  
  
  
  In case you are interested, that's my definition of the table:

  DROP TABLE myenterprise;
  CREATE TABLE myenterprise(
  city VARCHAR2(10), 
  storeid VARCHAR2(10),
  month_name VARCHAR2(10),
  total_sales NUMBER);
  
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id1', 'January', 1000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id1', 'March', 7000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id1', 'April', 2000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id2', 'November', 2000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id3', 'January', 5000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('london', 'id4', 'Janaury', 3000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('london', 'id4', 'August', 6000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('london', 'id5', 'September', 500);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('london', 'id5', 'November', 1000);

  It is clear that thet Analytics is reduntant here...
  You can even use AVG or any analytic function...

  SQL> SELECT city,
    2         avg(SUM(total_sales)) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY
    3  FROM myenterprise
    4  GROUP BY city
    5  ORDER BY city, TOTAL_SALES_PER_CITY;
  
  CITY       TOTAL_SALES_PER_CITY
  ---------- --------------------

• Questions about the export of PDF with India CS5.5

  Hey all,.

  A few questions about the export to PDF of the most recent version of India.

  First of all, I noticed it seems to take much more time to access a PDF file. Any suggestions about how to speed up the process? It took 8 minutes to generate a PDF low resolution (for printing) of a document of 24pp with placed images and vector graphics. Wow, that's a long wait, especially for evidence.

  Second, the background task... If I get it will make this PDF of 8 minutes and then more work on the document, which is exactly in the PDF? Usually, I have save before making a PDF or printing. Thus, the latest version is saved which will be in the PDF?

  (Either incidentally, this ability to work on the doc while generating a PDF file seems kind of weird. Generally, we do a PDF for proofing, or even for printing, when any changes have been made and that everything is "final". Therefore, I see no advantage in being able to work on my document while it is making a PDF file, I am probably once your revisions for the moment. I must say that I like the progress bar that you get when you perform an interactive PDF, as you know that you can not work on the document when it is on the screen...)

  Thank you as always.

  Good, people. Wanted to just follow this and post my results. It turns out that the problem is somewhere in the Illustrator file. I never had the time to guess what work plan was the culprit. Other India files PDF files is transparent and not a lot of time.

  No resolution, unfortunately, just good to know that it is not all India files on my system. Phew!

  THANK YOU for your advice.

• Questions about the implementation of clusters of storage and DTS on active cluster

  I have a few questions about the implementation of clusters of data store and SRS storage in VSphere 5.1.

  We have a data center with about 15 HP blades and a few servers non-lame.  The hosts are all either VSphere 5.0 or 5.1.  Our back-end storage is an EMC VNX 5700 with about 20 stores of data.  All the VMWare is managed by VCenter 5.1 running on a dedicated physical machine.

  Currently, each data store is used individually; No piles of data store are put in place.  When a new virtual machine is created, the administrator usually chooses the data with the most space store.  Periodically, we will go back and manually storage vMotion machines to balance the load.

  Recently, we have expanded the VNX storage, so we now have LUNS in different pools, with different levels of performance.

  What I would do is set up for the data store clusters, so that us when a virtual machine is created, the administrator must not know what data store is in which pool.  Also take advantage of the DRS storage so that the burden of storage will be "refine" himself a little.

  I know the setting up of a cluster of storage in a 'clean' environment is quite simple, but my concern is creation/conversion data warehouses existing in active production in the cluster, while they are used.

  If I access the screen "data warehouses and store data from clusters ', right-click on the data center and create a cluster, and then move the various data stores in the new cluster, will there be an interruption in the production running systems?

  I also wonder about activation of storage i/o control.  It is not currently enabled on data warehouses.  I know it's useful for the StorageDRS, but will be allowing any negative impact on the system?  If I turn on the warehouses of data, is there anything else I should do or set in addition to all that allows him?

  Finally, we are in the process of Site Recovery Manager configuration.  SRS has an impact on the configuration of the data clusters and DTS store?

  Thanks in advance for your comments.

  Hello

  Clusters of data and using DTS store doesn't impact RS even if you create a cluster of data store for storage of replicated data and another for everyone else, this way you machines virtual you want to replicate are not moved on warehouses of data that are not replicated , but will still have the ability to move if there is a conflict.

  Gregg

  With all due respect but SRM and DTS don't go together. SRM does not at all support the use of DTS. So if you are configuring SRM forget DTS for now.

  Reason for this is that SRM knows no DTS and VMs can be in flight when a failover should occur, and bad things can happen. Also, the protection breaks when a virtual computer is moved between data warehouses in a cluster data store.

  In short: don't go there.

• Question about the database update for Vsphere 4.1 to 5.1

  Hello

  We are about to upgrade our environment vsphere 4.1 and 5.1. I have a question regarding the upgrade of the vcenter server. Today, we have installed SQL SERVER 2005 Express database and what I get when I run the setup I will be invited to install 2008 r2 express or use the existing database. I guess I picked the new installation 2008 r2 express database? This will keep my DB inventory and just install the new DB SSO and tables?

  I read that you need to run som aswell from the installation CD SQL queries but are - that if you choose the existing database?

  hope you understand

  If you are doing a new installation of 51u1/5.1, the DB that is installed is 2k8R2 express... However, on the update from versions 4.x 2 k 5 db is preserved.

• questions about the depth of Panel with little information in Photoshop

  I was looking at the Info Panel (Windows > Info) in Photoshop CS 6 recently and have a few questions about what I see here.

  1. on the information panel, the RGB values range from 0 to 32768 (15 bits) if I'm using 8-bit or 16-bit.  Why 15 bits?  It is a 2s complement thing?

  2. sometimes I see the CMYK values given as % or 100%.  Sometimes I see the number given with a point of exclamation, i.e. 100!.  I don't know what conditions cause the exclamation points.

  3. If I add a Hue/Saturation layer, the RGB values will display as two numbers, i.e. 32768/32768.

  4. If I'm in 16-bit mode, the info panel displays values of 0 to 32768 as shown above, but if I go to a Committee of color selection, values are between 0 and 255.

  5. my camera has a 14-bit A/D per channel.  If I load a RAW image from this camera in 16-bit mode, photoshop place the 14 bits in the money services businesses?  In 8-bit mode Photoshop just truncates the LSBs?

  I'm not having a problem with this, I just want to understand what is happening.

  Thanks for any idea that you can provide.

• Question about the power option "Sleep with a password on wakeup"

  What is the difference between sleep with a password required to wake up and lock? I understand that if I choose the lock, other users can still connect?

  Hello Jim,

  Please keep us updated on the status of the issue. I apologize for the late response.

  I would like to inform you that if you have not set a password on your user account, then Windows will not ask for the password to unlock or wake the computer from sleep mode. If you move the mouse or press a key on the keyboard, the computer will automatically unlock or to wake up the fashion 'sleep'.

• A few Questions about the slices from Photoshop with Dreamweaver

  1. I noticed later with CS4, if I have several layers to do the bearings once I am in Dreamweaver that the layer under the main switch, does not export.  I think it was.  I then disable the button 1 (the top one) then this 2 button is visible and export the images AGAIN...  Usually in another folder, so it replaces all the previous images.  How can I get all the layers and slices to export in one fell swoop?  I think I'm missing a checkbox somewhere but can't find it.

  2. If I keep all slices in the same places they run and do not change anything with regard to their positioning.  Could I make graphic changes to a slice and then ONLY to EXPORT THAT SLICE?  He seems to want to export all the slices and I feel that could make me have to recode everything new in Dreamweaver.

  3. Finally, you guys actually code the slices into photoshop or dreamweaver?  I think you can do one, but I do it in dreamweaver because that's where I do rollovers.

  I KNOW I'm doing something wrong and I try to understand what he.  Now I design a webpage, slice it upward, export it in html and graphics, then in dreamweaver, I have to remove a slice, then add once again as a rollover image in DW.  Seems wrong, but it does not work.  It's just a pain because if I have to make changes to the site, it seems that I have to re-export all of PS againnnnnn and then it all with recode bearings etc in DW.

  Thanks for all the advice and answers!

  1. you must save each State separately unless you make a psd for buttons only, then you can copy - paste the buttons and record all the States in the form of separate buttons at once.

  2. by default, that the images are placed in a folder of Images, if it does not find one then he creates then save your image then just outside the pictures folder or change the behavior of the dialog box save optimized slot by selecting from the drop-down list of settings and deselecting the Images to put in the box of the folder for saving files section

• Two questions about the ACS 5.1: password aging and allowing multiple disabled accounts

  Hello

  I test in ACS 5.1 password aging, and I discovered that you can have only one global setting for the password for all the accounts internal life. Is it possible to exclude some internal accounts of this global password aging policy? I would like to have number of accounts, passwords should not be aged at all...

  Second question: when I was testing password aging, I set myself to life of password in 4 days with warning after 2 days. All accounts in my test of the ACS configuration are now disabled, because 4 days has passed when I changed it. Is there a possibility to allow multiple accouns at once, or do I have to activate 500 internal accounts manually, one by one?

  Thanks in advance

  WM

  I'm not aware of any way to score internal as users with passwords as enver expire. This is done for admins ensure there is always an admin who can access the system

  In order to change the multiple/all documents for internal users, the following approach can be taken:

  1. Go to the list of internal users and press "Export" then 'Start export' and 'Save file' export user records to a csv file
  2. Edit the file. In the title 'active' column replace 'FALSE' to 'TRUE' for all records. Save the updated file
  3. To the page that lists internal users, tap "File Options", select "Update", and then click next to access the section "Import a file" Wizard. Select the file saved in step 2) and tap on finish

  Afetr imort is completed, all records of internal user should now display "Enabled".

• Question about the migration of mass of files and permissions

  Hello

  I'm moving 2TBs of files from one external hard drive to another, but every time that I try to do a file mass transfer from one day to the next it eventually fail due to permissions for some files. I looked at the files on that he objected and I read and write permissions on them, as you would expect.

  What can I do to fix this?

  Try to run repair permissions and ACLs on your record. A repair permissions with disk utility does not have anything in your folder. Boot from your recovery partition now command-keys R in the menu utilities launch Terminal. In the Terminal, type: resetpassword , then press return.  (Note: you won't be reset password)

  Click the icon for the hard drive of your Mac at the top. In the drop down menu below, select your home folder. At the bottom of the window restore Home Directory Permissions and ACLs. Then, click on the Reset button. When the prompt returns to the command line, you can leave out Terminal.

• Question about the installation of XP with an OEM disc and using the number of CoA HP

  Hello

  I have a DC5100SFF that I bought refurbished last year, and it came not with all drives. It comes with windows XP pro and has the CoA sticker with the activation code.  It also has "HP" written on it.

  I thought to wipe the hard drive and reinstall XP Pro in the near future.  I have an an OEM Windows XP Pro disc, but it is not specific to HP. The CoA sticker has been removed from the new drive (and the package is not open), but there is nothing on the packaging to indicate what OEM brand (its likely it was another popular provider).

  My question is, if I install XP from this disc, he on my machine can use the number on the certificate of authenticity to activate it, or do I need to use a specific disc HP XP Pro?

  Thank you

  Hello:

  David is correct. You don't have the product key if you use recovery discs.

  However, I believe that you can still get the recovery disc for your Business from HP desktop PC.

  Just dial 1-800-334-5144 and inform the representative of customer services that you need a set of quick restore CD.

  You will need to provide the model number and serial number.

  A game costs $10.00.

  As for your other question... If someone has already used the product key XP pro on the sticker on your PC, you can use any disk XP Pro OEM installation and enter the product key.

  I do it all the time. I used OEM Dell on HP PC disks. Never had a problem.

• I have a question about the ESXi upgrade using Update Manager...

  This is probably a stupid question, but I've never played and update ESXi using Update Manager.  We need to update ESXi ESXi 4.1 4.1 servers before vCenter 5.0 U1 from U2 (there is a known issue where the ESXi 4.1 servers receive the GROUP after upgrading vCenter to 5.0 U1).  We used HP ESXi image to install ESXi on our servers for new installations.  This image contains ESXi.1 U2 as well as the drivers of HP and CIM.

  4.1_U2_Oct_2011_ESXi_HD - USB-SDImgeInstlr_Z7550 - 00241.iso

  Can this same image HP ESXi 4.1 U2 that we used to install to new ESXi servers, be used to upgrade our 4.1 4.1 U2 ESXi servers using the Update Manager?  Or, upgrade package should be used for the upgrade?  Also, if an upgrade package must be used, is it OK to use one provided by VMware, or will be losing our HP specific drivers and CIM to do this?

  Thank you

  Hello

  You can import custom HP ESXi 4.1 U2 ISO in Update Manager (don't forget to use the latest version of June 2012, available here: https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=HPVM06) and update the hosts with her.

  In a second step, you can then import the last custom HP ESXi ISO 5.0 (available here: https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=HPVM09) and update the hosts again with her.

  To be on the current ESXi 5.0 patch level you finally apply the latest patches from VMware via the Update Manager.

• Question about the key to restore with Vista premium on Satellite A100 CD

  I have a Satellite A110 which is compatible with Vista, but recovery of product is Windows XP.
  I use my cd of restoration of friends and it work perfect until it tell me to put the product key for vista Home premium
  I used the product key with the cd, they said it is not acceptable.
  give me the solution

  Solution? Buy your own Vista and use it with the activation code valid. The button located on the bottom side belongs to the Windows XP Home edition version, that you got with recovery media. It is not a kind of universal key.

  All that s!

• Questions about the alternative syntax using DAQmx

  Hi all

  my group has started to use an alternative syntax for functions DAQmx. Here is the part of our original code:

  nitWFM-> AOChannels.CreateVoltageChannel ("Dev1/ao0", _T(""), dMinimum, dMaximum, DAQmxAOVoltageUnitsVolts);
  nitWFM-> AOChannels.CreateVoltageChannel ("Dev1/ao1", _T(""), dMinimum, dMaximum, DAQmxAOVoltageUnitsVolts);
  nitWFM-> AOChannels.CreateVoltageChannel ("Dev1/ao2", _T(""), dMinimum, dMaximum, DAQmxAOVoltageUnitsVolts);
  nitWFM-> AOChannels.CreateVoltageChannel ("Dev1/ao3", _T(""), dMinimum, dMaximum, DAQmxAOVoltageUnitsVolts);

  that became:

  DAQmxCreateAIVoltageChan(nitWFM,"Dev1/ao0","",DAQmx_Val_Cfg_Default,dMinimum, dMaximum,DAQmx_Val_Volts,));
  DAQmxCreateAIVoltageChan(nitWFM,"Dev1/ao1","",DAQmx_Val_Cfg_Default,dMinimum, dMaximum,DAQmx_Val_Volts,));
  DAQmxCreateAIVoltageChan(nitWFM,"Dev1/ao2","",DAQmx_Val_Cfg_Default,dMinimum, dMaximum,DAQmx_Val_Volts,));
  DAQmxCreateAIVoltageChan(nitWFM,"Dev1/ao3","",DAQmx_Val_Cfg_Default,dMinimum, dMaximum,DAQmx_Val_Volts,));

  We changed it to a function that seemed to only work for us in a single syntax (DAQmxSetWriteAttribute (nitWFM, DAQmx_Write_RegenMode, DAQmx_Val_DoNotAllowRegen))

  My question is, what is the alternative syntax for the following lines? :

  nitWFM-> Control (DAQmxTaskVerify);

  CNiDAQmxAnalogMultiChannelWriter, writer (nitWFM-> Stream);

  because keep an error in this way.

  Your answers are greatly appreciated.

  Hello

  "" "" "" "" The first function can be found in the C reference help by clicking on start "all programs" National Instruments "NOR-DAQ ' Text Based Code Support" reference of C OR-DAQmx help and expand the functions C of NOR-DAQmx "task/Configuration control ' Advanced ' DAQmxTaskControl. This explains the function and syntax to use.

• Technical question about the naming conventions used in the API

  What does the prefix 'PF_' rest in all the function names in the SDK of EI?  It is not immediately obvious to me and was just curious.  I would like to have an idea of how the naming conventions came when I learn a new code.

  Thank you!

  Interesting question.  PF stands for package of plug-in filter in After Effects.
