  How to change the query to do this...?

  Ok. I looked more carefully at your sample and it looks like you are looking for:

  SELECT  RI.RESOURCE_NAME,
          TR.MSISDN,
          MAX(TR.ADDRESS1_GOOGLE) KEEP(DENSE_RANK LAST ORDER BY TR.MSG_DATE_INFO),
          MAX(TR.MSG_DATE_INFO)
    FROM  TRACKING_REPORT TR,
          RESOURCE_INFO RI
    WHERE TR.MSISDN IN (
                        SELECT  MSISDN
                          FROM  RESOURCE_INFO
                          WHERE GROUP_ID ='1'
                            AND COM_ID=2
                       )

• Using a single server for Multiple Instances of the APEX HTTP

  Our company DBA asked if it would be possible to outsource the server part of HTTP of APEX from DB servers. In other words, it would be highly preferable as DB servers * only * start the Oracle database software.

  We know that we can install the HTTP server on another box, but in thinking how to that, we were wondering if it's really necessary to create a separate HTTP Server installation for each instance of the APEX. What we would really like to do, is have a HTTP server for all our our boxes of Dev and several (but not one) for each of our superior environments; implementation stage, qa, prod, etc..

  Right now, each instance has a file single dads.conf on every box of DB. So, if we we to try to consolidate, we need some way to incorporate several dads files and associate each correct instance.

  Someone has already done this or (preferably) to have some examples?

  Thank you

  -Joe

  The second page on the link provided José begins immediately with the "Configuration of several databases".

  Yes, you can consolidate permanently. It is a common practice that was also available with Apache/mod_plsql, OSH and now with APEX earphone 2.

  Thank you

• Select the last value for each day of the table

  Hello!
  
  I have a table that contains several measures for each day. I need two queries on this table, and I'm not sure how to write them.
  
  The table stores the rows (sample data)
  

  *DateCol1                 Value       Database*
  27.09.2009 12:00:00       100           DB1
  27.09.2009 20:00:00       150           DB1
  27.09.2009 12:00:00       1000          DB2
  27.09.2009 20:00:00       1100          DB2
  28.09.2009 12:00:00       200           DB1
  28.09.2009 20:00:00       220           DB1
  28.09.2009 12:00:00       1500          DB2
  28.09.2009 20:00:00       2000          DB2

  Explanation of the data in the sample table:
  We measure the size of the data files belonging to each database to one or more times a day. The value column indicates the size of the files of database for each database at some point (date in DateCol1 European model).
  
  
  What I need:
  Query 1:
  The query must return to the last action for each day and the database. Like this:

  *DateCol1       Value      Database*
  27.09.2009        150          DB1
  27.09.2009       1100          DB2
  28.09.2009        220          DB1
  28.09.2009       2000          DB2

  Query 2:
  The query should return the average measurement for each day and the database. Like this:

  *DateCol1       Value      Database*
  27.09.2009       125          DB1
  27.09.2009      1050          DB2
  28.09.2009       210          DB1
  28.09.2009      1750          DB2

  Could someone please help me to write these two queries?
  
  Please let me know if you need further information.

• When I open Task Scheduler and click on MSE for planning, I get the following warning. General Page initializatin has no 0 x 80070534

  Original title: Task Scheduler

  When I open Task Scheduler and click on MSE for planning, I get the following warning.

  General Initializatin page failed,

  The specific error is:

  0 x 80070534: no mapping between account names and security IDS was done. Year error has occurred trying to retrieve task account informaiton. You can continue to edit the subject of the task, but will not be able to change task account information.

  I then press the ok button and it goes to the task, schedule, and the settings box.

  When I check in scheduled tasks, to see if they ran as planned, the last run time column NEVER said, and the status column indicates

  COULD NOT START.

  In the morning, I always get this error message:

  A task could not run...

  Do you know what I'm doing wrong? Can it be fixed?

  Thank you Tim

  Is there a password the user account in which the task is scheduled?  You cannot schedule a task to run under a user without password account.

  You can also take a look at advanced > view the log window scheduled tasks.

• (For each) components in the OSB

  I try to use component "For-Each" to perform a loop on the message to bulk out bulk and publish individual messages of the loop. However the loop does not run several times. It passes through the only once for each component. The key message is ';' separated from text messages.
  
  There are about 4-5 different parameters to be set for the component. as a County, index, param, and xpath.
  What best values to put in it so that the component gives the desired effect?
  
  
  Thanks in advance.

  You try to say I'm going to use a component of the NEWSPAPER inside the component for EACH?

  N ° it is a control sample if the loop is getting executed as required. You can completely ignore the alert/Log and place your logic. With sample data that you have posted, I have confirmation code posted earlier worked on my local machine. You may need to change depending on your use case.

  But with my specified parameters for EACH component is not executed at least once.

  The first glance, it seems that you XPath: v_XML. BUlkMessage.Transaction (v_XML here are the above XML code) has something to do with your problem. You should return table of elements that confirm specific condition. With the help of .//transaction is a way to query all the with in the specific variable.

  Thank you

  How can I make a cell formula will apply for the entire column? For example D2 appears B2 - C2. How can I copy this formula for each cell in the column?

  If you want the formula is the same (B2 - C2) in the cell of each column you must change it as ($B$ - 2$ C$ 2). Then copy it, select the whole column and paste.

• Type a table defined clusters to hold configuration data - definition of default values for each element of the array

  Hello

  I was wondering if I could get some information and opinions on the use of an array of type defined clusters to store configuration data.  I am creating a program to test several EHR and wanted to have a control of type defined for each HAD with the information needed to create the DAQmx tasks for all signals for it must HAVE.  I am eager to do so that the data are encoded in hard and not in a file that the user might spoil.

  Controls of type def are then put into a Subvi who chooses as appropriate, one based on the enumeration of Type DUT connected to a case structure.

  I have problems with the control of the defined type.  I see issues when you try to save a configuration unique to each element of the array in the array of clusters.  Somehow, it worked at first, but now by clicking on "Operations on the data--> default font of the current value ' on individual elements of the cluster or the entire cluster (array element) does not save data when I re - open the command def.  What I am doing wrong?  I'm trying to do something with the berries of the clusters that I shouldn't do?

  I enclose one of the defined reference type controls.  I tried to change it bare to see if that helped, but no luck.

  To reproduce, change the resource string for the element 0 of the array and do the new value by default.  Then close the def of type, and then reopen it.  The old value is always present in this element.  The VI is saved in LabVIEW 2012.

  The values of a typedef are not proprigated to the instances of the control. They get if created WHEN data values have changed. They will be not updated with the changes to come. You must create a VI specifically to hardcode your values or to implement a file based initialization. The base file would be much better and more flexible. If you don't want users to change the data simply encryption. There is a wedding blowfish library that you can download.
