• Why the cfreturn is null?

  I have mandated a call to a cfc which is a ftp get into a local temporary file. Then he reads the file and is supposed to return the content of the file as a string cfreturn. I know the code works, when I remove CFC in a file usually cfm, it does exactly what is expected

  However, in my proxy callBackHandler, the return of cfc is null.

  < cfajaxproxy cfc = "ftpfunc" jsclassname = "jsobj" / >

  function getFTP() {}

  ...

  var instance = new jsobj();

  instance.setCallbackHandler (ftpSuccess);

  instance.setErrorHandler (ftpError);

  instance.setReturnFormat ('plain');

  instance.getJCL (lpar, remoteFile, userName, password);

  }

  function ftpSuccess (ftpReturn)

  {

  If (ftpReturn.length == 0)

  Here thrown error: "ftpReturn is Null".

  {

  Alert ("your FTP get returned an empty file");

  }

  }

• Why the Firefox 4 is not restore all the sessions that were open at the time? Before the update, I've been invited either ("SAVE AND QUIT") or even if she closed UNEXPECTEDLY (crushed), he AGAIN restored. New version does not offer "save and exit".

  Question
  Why don't Firefox4 restore any sessions that were open at the time? Before the update, I've been invited either ('SAVE AND QUIT'), or even if it closed UNEXPECTEDLY (crash etc) it STILL restored everything. New version does not offer "save and exit".

  Now, Firefox always stores the old session which you can access from the history menu by selecting "restore previous Session."

  If you always open the last set of tabs, another approach is the following:

  1. Click on the orange button Firefox, then select options to open the options window
  2. Go to the general Panel
  3. Change the setting "When Firefox starts" to "show my windows and tabs from last time '.

• Why can't I change the username to the server in the mail?

  Just upgraded to El Capitan and now does not work my AOL e-mail account. The problem is the user name is incorrect by the name of the incoming server, but I can't change it because it is grayed out. Someone knows why?

  I finally got to work in Yosemite, but I had to create an account with a username of @example. com The problem is caused by having to change from Verizon to AOL mail and the user name is always "[email protected]". I could get fixed and make any changes that I needed. I had to modify the plist to make changes, but apparently there was another place where El Capitan found the information and create a new account. The preferences file indicates the username for the incoming "[email protected]", as the original server the plist file doesn't seem to be the same thing now. I also made sure the box is unchecked to automatically manage settings.

  Uncheck automatically detect and manage settings in the Advanced tab of the account preferences in Mail.

• Why the JTable getTableCellRendererComponent parameter can be null?

  Hello
  I have a class that implements TableCellRenderer.
  TableCellRender interface has a single method:

  getTableCellRendererComponentender (JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) 

  and this method accepts JTable as null - http://download.oracle.com/javase/1.3/docs/api/javax/swing/table/TableCellRenderer.html.
  
  Why can we get null JTable?
  When I run my program in the getTableCellRendererComponentender method, I run

  this.size = table.getColumnModel().getColumn(column).getWidth();

  But this code is failed because the table is null.
  The table is defined in fact but I do not know why is not not passing as a parameter to getTableCellRendererComponentender.
  
  Thank you.

  In case it wasn't clear enough: what happens is that Swing tent paint the header that you have already removed the table (replacing it with a new one). This is the table of this header removed which is null parameter.

  The new header is not added to a hierarchy of visible components, so it is not rendered.

• Why do I own this blocking session / blocked

  Oracle 11.2.0.4 SE a 64-bit

  Oracle Linux 5

  We have a task that runs every 5 minutes to detect blocking sessions / blocked.  When it detects an email with the details is sent.  Conduct of query is the following:

  select NVL(s1.username,''null'') username1,
                  s1.machine machine1,
                  s1.sid sid1,
                  s1.osuser osuser1,

                  v$session s2,
                  v$locked_object lo,
                  v$sqltext sqlt
           where s1.sid=l1.sid
             and s2.sid=l2.sid
             and l1.BLOCK=1 and l2.request > 0
             and l1.id1 = l2.id1
             and l2.id2 = l2.id2
             and s1.sid = lo.session_id
             and s2.sql_address = sqlt.address
             and s2.sql_hash_value = sqlt.hash_value
             and sqlt.piece = 0
  

  Normally things are fairly quiet except on the occasion one of my power forgot to engage users.  But last week I started to have notification that a session belonging to me (ESTEVENS) was blocking one or more sessions held by me.  Still, he arrives at 21:00 and fades within 5 minutes before the next review.  The sql code associated with the blocked session is always the same.  Here is a representative sample, with company data obscured.

  Block user - ESTEVENS

  Machine - myserver.mycompany.org

  SID - 433

  OSUSER - oracle

  -PROGRAM [email protected] (J001)

  OBJID - 12451

  Blocked user - ESTEVENS

  Machine - myserver.mycompany.org

  SID - 200

  OSUSER - oracle

  -Program [email protected] (J002)

  SQL: UPDATE HS_FDS_CLASS_DATE SET FDS_CLASS_DATE = SYSDATE WHERE FDS_

  By comparing the time of the block and SIDS reported with DBA_SCHEDULER_JOB_RUN_DETAILS content, I was able to follow some scheduled tasks 'load '.  These jobs do a SELECT... IN... OF < db_link >.  Because the table is locked is HS_FDS_CLASS_DATE, I found notes 1536085.1 describing a bug with the use frequent or simultaneous to a db_link, supposed to be fixed in 11.2.0.4 but my experience says otherwise.  However, I can deal with all that.

  But my real question is how to get my username attached to these sessions?

  Understand your question, I hope...

  It happened to me, that if I use my "DBA1' to create one job to another user"USER1", my user name is indicated as the USER name in the session, but 'The ANALYSIS of the USER' are the owner of the task.

  I think it's normal, but I still don't know why.

  Edit: Duh! It seems that it is documented Overview of job creation

  Because no destination_name attribute is specified, the task runs on the (local) database of origin. The job runs as the user who created the work.

  Kind regards

• Why the result of the download on IR is different from the list that we saw

  APEX 4
  
  Interactive report received 39 records, including sql like statement below:

  select * from table from dept=NVL(:dept,dept)

  For the flexible application, I put the dept element to change the filter above.
  
  but when I download to CSV for IR, I found the result more than 39 files, is not a number of records in the table.
  
  If amended the statement of the following:

  select * from table from dept=:dept

  nothing has been uploaded. the result is null.
  
  Why it happen? How can I get the result like what we saw?
  
  Please help me!
  
  Thank you very much

  This article describes the problem of standard reports, but basically, it's the same thing for your report:

  C:\Documents and Settings\UserName\Desktop\Unused desktop shortcuts.

  But back to your question:
  I put t know why the office cleaner chooses the most used icons on the desktop for cleaning but why don t you disable this feature?

  1. right click on an empty spot on the desktop and then click Properties to open the display properties dialog box.
  2. click on the Desktop tab.
  3. click on the desktop to open the desktop items dialog box customize.
  4. Click to disable the wizard desktop cleanup run every box of 60 days.

• Why the acquired data are not from min to max (DAQmxCreateAIVoltageChan, PXI-4472) values

  Hello

  I'm developing a program for the PXI-4472 acquisition on opensuse 11.4 device (linux 2.6.34).

  I try to acquire analog data and to read in a wav file.

  Configure the task of acquisition with the following functions:

  DAQmxCreateAIVoltageChan(taskHandle,"Dev1/ai0","OnboardClock",DAQmx_Val_Cfg_Default,-10.0f,10.0f,DAQmx_Val_Volts,NULL);

  I don't understand why the data stored in the wav file are not-10V,-10V but-5V, 5V... (the value of the gain is 0dB). (Perhaps a scale of 0.5?...)

  Thanks for your help,

  You're right, in my example, I considered as unsigned data.

• Remote Desktop. Why the differences?

  In this case I use Remote Desktop to connect a system from Vista Home Premium to Windows XP Professional on a local network.  Still, it establishes a connection, but can behave in 3 different ways:

  1. the session starts and works very well.  After entering the password (I ask the password), it goes directly on the desktop of the remote PC

  2. the session begins, then I am taken to the login screen of the normal remote PC (what you expect to see if you were working on this PC).  When you enter the password, it then goes to the desktop.

  3. I get the blah "can not load your profile...". ", where Windows will load a temporary profile that takes you back office.  Logging and lumbering back to still seems to work, i.e. log on normally.

  So, no show stopping issues, but why?  Certainly why the difference between 1 and 2?  Thoguh that you arrive at the same place, with 2, you get also present with all the other user accounts on this computer.  For my part, it is not a constraint, but what happens if I don't want to have other possibilities of connection presented?  Remote Desktop Client indicates the account to Log On with, so why present all others?  On the question of the profile, there are a lot of intel available, but I have yet to find the cause in my configuration.  It's exhausting rather than as a problem, but I would be very happy to eliminate this behavior.

• vSphere client using the name Netbios on ESXi host does not connect using the credentials of a Windows session

  I have 3 ESXi 5.5 hosts, all connected to a single server vCenter, where we try to authenticate directly to the host by using the windows logon credentials. I have installation of the Administrators group of ESX and filled with the admin accounts that I want to be able to authenticate to the host. The Netbios name of the domain is tstdomain (for example) where the domain name is tstdomain.com. If I connect directly to a host and check the checkbox 'Use Windows Session Credentials', the vSphere client will default by using the Netbios name of tstdomain\adminusername and the connection will fail indicating that the username and/or password is incorrect. If I enter the domain name of tstdomain.com\adminusername, I am able to connect to the host without error.

  Does anyone know how get past that this matter have the vSphere client uses the domain name or to use the Netbios name and connect with the credentials to active directory? I looked by editing the file/etc/hosts and checked that the SPN of the host is correct in active directory with the command hostname setspn - l, with no luck on one. I also tried to change the field of research for the Netbios name of tstdomain rather than the tstdomain.com domain name, also did not work.

  Thanks in advance for your suggestions on how to correct the problem.

  Seems that this issue was due to a slow network and the connection timeout when you try to talk to the domain controller. I am able to connect with windows creds now, but the connection is very slow. I increased the default period of 30 to 60 seconds to help work around the problem.

• Hide the username / password when connecting to the database

  I need to find a way to hide the user name / password when connecting to the database (via a script), or by encryption or any other method that hides this information when I connect to the database.

  Please help me.

  Hi Luiza,

  Try to find out why the portfolio method does not work, check the implementation using ref 340559.1 Note

  Check also for example client and server versions / compatibility, evolves sec_case_sensitive_logon relevant parameter (as a test, because it must be true) etc.
