• How to omit elements/attributes if the value of the element is zero?

  Hi gurus
  
  It's me again. with a quick question...
  I'm sure everyone knows the difference between these two statements (running in the SCOTT schema):
  
  Select
  XmlElement ('employees',
  XMLAGG)
  XMLFOREST (comm as "SalesCommEmployee")
  )
  )
  EMP;
  
  Select
  XmlElement ('employees',
  XMLAGG)
  XmlElement ("SalesCommEmployee", comm)
  )
  )
  EMP;
  
  First statement out fewer records because XMLFOREST shows nothing if the value of the element is null.
  But what happens if element has attributes?. Say:
  
  Select
  XmlElement ('employees',
  XMLAGG)
  XmlElement ("SalesCommEmployee", xmlattributes (empno as "id"), comm)
  )
  )
  EMP;
  
  Is it possible to omit any element (including attributes) if the value of the element is set to zero.
  Of course, it is a simplistic example, in this case, a WHERE clause would solve the problem.
  In my particular case, I am managing a huge SELECT with multiple levels of xml and some elements (with attributes), may have null values, and must be included in this case nothing.
  
  I am considering a dirty search/delete option on the output, but I think that a more elegant solution must exist.
  
  Can you give me some advice?
  
  Thank you

  Hello

  You can use a CASE statement, DECODE or NVL2 functions.

  Here is an example with NVL2 (returns 2nd argument if the 1st is not not null, otherwise the 3rd):

  SQL> select xmlserialize(document
    2           xmlelement("Employees",
    3             xmlagg(
    4               nvl2( comm
    5                   , xmlelement("SalesCommEmployee", xmlattributes(empno as "id"), comm)
    6                   , null )
    7             )
    8           )
    9           as clob indent
   10         ) as result
   11  from scott.emp

• Transactions involving several RM in Tuxedo

  Hi Little Todd-Oracle.

  Assume a bank with server both B1 and B2 branches, each having its own database (Oracle) DB1 & DB2 (mysql).

  Take the B1 branch has an A1 account & branch a A2 B2.

  Suppose that a1 has 100 balance & account a2 has balance 0.

  At this point all plugged balance is 100.

  Assume that a transfer of 100 is launched from A1 to A2.

  Suppose that during this transfer operation was only half committed i.e. the balance was reduced on DB1, another customer (customer audit) is started for the balance of the whole Bank branches.

  Suppose the client verification transaction ends before the valid transfer transaction the increase in balance on DB2.

  The audit client would yield a ZERO balance which is incorrect.

  The pdf file attached shows the sequence diagram.

  My first question is

  Is there a way to Tuxedo to hold to start new operations (i.e. block to tpbegin/tx_begin calls) while a transaction is still committing (tpcommit is current)?

  My second question is

  Is it another way as a tuxedo configuration setting to fix this?

  My third question is

  This problem comes under the domain of a TM that Tuxedo?

  If it's not then how this issue is resolved in Tuxedo ATMI applications?

  Thanks in advance.

  Best regards

  Abbas

  Hi Abed,

  My understanding of isloation serializable is the RM will acquire both read and write locks.  Select statements would "for update" as part of the selection, which looks at the database to take an exclusive lock at this time there.  So in your sequence diagram, select statements of verification transaction will block until validations of transfer in each respective database transactions that select statements of will transfer transaction out exclusive locks.

  Kind regards

• The column UBAFIL of V$ TRANSACTION

  I thought that UBAFIL indicates the number of file where the first block to cancel located.
  So the UBAFIL must always be in the undo tablespace files, right?
  
  But my test below shows different.
  

  SQL> select FILE_ID,TABLESPACE_NAME from dba_data_files where TABLESPACE_NAME LIKE '%UNDO%';
  
     FILE_ID TABLESPACE_NAME
  ---------- ------------------------------------------------------------------------------------------
           2 UNDOTBS1

  As you can see, undo datafile is 2.
  But below shows UBAFIL is 0
  

  SQL> select XIDUSN,UBAFIL from V$transaction;
  
      XIDUSN     UBAFIL
  ---------- ----------
          15          0
          14          0

  Kramer wrote:

  It would be START_UBAFIL, UBAFIL is the file where the most recent undo folder has been created.

  So the UBAFIL must always be in the undo tablespace files, right?

  Not quite - if you have not yet created a records to cancel the various columns of UBAxxx will be zeros. A case, you can use to illustrate this is to design a distributed query incoming.

• How to fill out a sparse table with zero

  Hi all
  
  I have a sparse table, most of the cells is null, but few of the cells is '1 '.
  
  I would like to fill the null with zero.
  
  This table is to rotate a transactional table into a table that describes the attributes and later for data mining
  
  
  I think so
  
  (1) make a user_tab_columns and copy / paste to make a script using NVL
  
  for example
  
  Select ' NVL('|| column_name ||) «, 0, » || column_name |'),' of user_tab_columns
  where lower (table_name) = "claims_t1".
  
  but I have a problem
  
  for example
  
  create or replace view claims_t2x
  as
  Select
  NVL ("Diagnostic Imaging' _SPEC_SUM, 0," Diagnostic Imaging' _SPEC_SUM) 'Diagnostic Imaging' _SPEC_SUM
  Of
  claims_t1
  
  I get the error ORA-00911: invalid character
  
  as the name of the column got ' ' ' in there.
  
  
  
  or
  
  Use 2) PL/SQL
  
  
  I just do a select and loop through all
  
  
  
  For 2), I don't know how I can get all the column attribute.
  As the attribute in the table operation is not fix so the number of column after swivelling isn't fix
  
  
  any idea?
  
  
  -Thank you very much for your comments.

  You can use nvl pivot by naming the values in quotes like that.

  CREATE OR REPLACE VIEW emp_v1 AS
  WITH pivot_data
       AS (SELECT deptno,
                  JOB,
                  sal
             FROM emp)
  SELECT JOB,
         NVL ("10", 0) AS "10",
         NVL ("20", 0) AS "20",
         NVL ("30", 0) AS "30",
         NVL ("40", 0) AS "40"
    FROM pivot_data PIVOT (SUM (sal) --<-- pivot_clause
                                    FOR deptno --<-- pivot_for_clause
                                              IN (10, 20, 30, 40) --<-- pivot_in_clause

• Several replicate consistency of transactions

  When you use the @RANGE function to divide the workload of treatment among several replicates we the transaction commit orders kept. If a REPLICATE is ahead of the other could it cause data inconsistency?
  
  For example, the following splits the replication load in two ranges (between the two processes of Replicat) based on the ID
  column of the table of the source account.
  
  Source.Account, Target.account, FILTER TARGET MAP (@RANGE (1, 2, ID));
  
  On the source, we have the following order.
  
  (1) update accounts set balance = "NEGATIVE";
  
  Update accounts 2) adjust the balance = "ZERO";
  
  Update accounts 3) adjust the balance = "NEGATIVE";
  
  Update accounts 4) adjust the balance = "POSITIVE";
  
  
  When we distributed transactionS based on the hash value of the primary key and if we have committed 1.2 to Replicat1 and assigned to Replicat2 and so Replicat2 3.4 ends before Replicat1, there will be data inconsistency.
  
  Can we preserve the order of validation when using multiple replicates.

  Hello

  When you use the @RANGE to split operations, it is still possible that a replicat is faster, then the other (s).
  This may cause the operations applied in a different order, and then in the original transaction.
  But this "contradiction" will be very short (unless one of replicates has a huge backlog, or stops)

  In your example, you use the ID field to calculate the hash value for the function @RANGE.
  As long as this field ID remains the same, the same record is processed each time by the same replicate, so when the replicates are finished, the data is the same as on the source, no inconsistency

• Mac Air drains almost zero during the night when the laptop is closed.

  In the morning a few last that I was wake up an empty battery and I were not able to find a reason why. For example, last night, I have to close to 33% and earlier this morning it is 2%. My laptop used may use one/zero to 100 during the night, so I don't know what it is.

  The laptop isn't a deal and is closing completely. During the closure, it is either not sleep or something it is waking up. I looked at the activity monitor and nothing takes too much energy (but something could stay while it is supposed to sleep, but I don't know if there is a way to check that).

  I'll leave it open tonight and just push sleep in the menu apple tonight and see how it works. Even if it works, I wish I could just shut up because this is supposed to be able to do.

  Also, I recently downloaded Skype plugin and it's, it's the only change I made in the time this problem started, which may have something to do with it.

  MacAir 11', at the beginning of 2014

• Can I remove "zero-byte" & "there are no ready application to open the document...". » ?

  As above.

  (1) If a Cache shows "zero-byte" in the list of information, safely remove it?

  (2) in addition, safely remove it ESPECIALLY if it says "Apple" in the name?

  (3) and, if "there is no set application to open the document...". "etc, can I safely delete that also?

  I will soon migrate to another mac and see no need to take things with what I don't need.  I won't delete the above, if I need.  As long as they do not have a hidden need to exist, so I don't have need of them.

  To be honest, when I click on read the information, I see nothing that I understand anyway.

  For 1 and 2 OK to delete it.

  What do you mean for #3? Is this a real file? A zero-byte file?

  What are the names of files?

• Several weeks ago, Firefox displays a receipt for a transaction at Costco and become totally insensitive. He still goes there when opened.

  When you complete a transaction at the Costco Photo, my display reception and Firefox has become totally insensitive. He was waiting for something, and the led was "busy". He couldn't be stopped using the Tak Manager to complete the process. Therefore, whenever Firefox is opened, he went straight to this page and became unresponsive. I uninstalled Firefox and use another browser for several weeks, but when I reinstalled Firefox and its opening, the same reception screen appeared, the 'busy' circle and Firefox could only be stopped by the Task Manager. I erased some cache and browsing history, but nothing is. Any ideas?

  You all link shortcut on the desktop you? Use one of them. Or,
  If you have a Firefox icon in your taskbar, right click and select
  Open a new window.

  This add-on can stop these pages; disable the button Script {web link}
  The button reject Script resembles the letter "M" and the title is the least Script, drag-and - déposer the button on a toolbar. If the button does not appear while nothing works, except rules of plug-ins.

  Type of topic: customization< enter > in the address bar.
  In the new window, locate the icon of the button Script reject. When you find
  it, hold down the left button on it and move it to where you want it to be.
  I suggest just to the right of the address bar.

  If your browser is locked up, just press the icon and close this tab.

• Cursor guard set to zero at the beginning of the address bar if the page loads

  Hello

  I have a boring (and weird) problem with Firefox: whenever I type in the address bar, the cursor will constantly reset to the beginning of the address bar. This only happens if another page load currently.

  By example, if I try to type in something like google.com it will tend to come out as le.comgoog, but only if I opened recently a few links and they always load the Web page. Therefore, it is very difficult to open a Web page if another load.

  This also occurs on the Favorites bar, because if I open a folder, it will close randomly (which makes it quite difficult to open another site), but only in the same circumstances.

  The problem seems to worsen the tabs more are loading - if it's just one I might reset after 5 seconds (or almost) but if I just open a folder of 10 bookmarks then google.com eventually became moc.elgoog because it is so often set to zero.

  Thank you!

  You can start Firefox - safe-mode to check if your problem is caused by an extension or theme (try the default theme).
  If from work safe mode then disable your extensions (Tools > Modules > Extensions or use the option in the window of safe mode) and re-enable one by one until you find the one that is the cause.
  Close and restart Firefox after each change.

• zero byte jpg 1000 files?

  I recently discovered 1000 of grayed out of jpg files in our user folder that tell all zero bytes and the claim was created in 1970 (not born then) and amended in 1984 (was in elementary school playing with Dataman.) Looking at the file name looks like that they are derived from our Photo/iPhoto library, although the file names one slightly modified. When I tried to put one in the bin I get this message

  "Some of the elements that you are moving are in use by another application. Move the items can cause problems with the application using them. Are you sure you want to move these items? ', although nothing seemed to happen when I did this and could then empty the trash.

  They don't seem to be causing no problem other than cluttering the folder of the user who is a pain.

  I wonder if it is safe to remove them and they came from?

  See you soon

  Try this:

  Quit all applications (not the Finder), even those in the menu bar if there are.

  Then sort the column 'genre', in list view Finder so that all .jpg files are together, select them all, move it to the trash.

  Restart the mac and empty the trash.
