• ORA-12170: TNS: Connect timeout occurred on the same host as DB

  Hello

  I just installed Oracle on mu Ubuntu 12.4 following the instructions here:

  http://www.Makina-corpus.org/blog/HOWTO-install-Oracle-11g-Ubuntu-Linux-1204-precise-pangolin-64bits

  and here:

  Install Oracle 11 GR 2 on Ubuntu 12.04 of the databases

  However, when I try to log on to the database, I created during installation using sqlplus, it hangs for a minute or two until it-error:

  ORA-12170: TNS: Connect timeout occurred.

  My tnsnames.ora:

  MYSIS =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = my_host) (PORT = 1521))
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = mysids)
  )
  )

  I checked that the listener is running and listening to the post 1521:

  s$ sudo netstat - tulpn | grep 1521

  tcp6 0 0: 1521: * LISTEN 16732/tnslsnr

  $ ps - ef | grep 16732

  Oracle 16732 1 0 06:58?        00:00:00 /opt/oracle/product/11.2.0/dbhome_1/bin/tnslsnr EARPHONE-inherit

  Thoughts?

  Finally managed to do run. The problem was that I have not read rights to tnsnames.ora.

• «A fatal problem occurred, stopping the service of VMware VirtualCenter.»

  Although I doubt it's related, after the problems in this number - and do work very well the the rest of the day, I walked into the Office to another topic!  Maybe it's related but I do not know...

  As I said, after you complete the migration, things seemed fine for the rest of the day.  This morning, I can't even on the server via vSphere.  For some reason, the service was not working and I can't restart.  Here is my error in the Windows Event Viewer...

• What does that mean? -This problem occurred because your graphics card does not support the required version of DirectX. This version of Windows requires a DirectX 9.0 compatible video card or newer.

  I tried viewing a presentation power point and got to page 2 and my computer crashed.  Thought on... what he did previously trying to display a PPP file, but I thought that it was not my computer to the actual file.  now I have my doubts and also this time an error message came that said... This problem occurred because your graphics card does not support the required version of DirectX. This version of Windows requires a DirectX 9.0 compatible video card or newer.  can someone tell me what I should do next?

  You left out which version of DirectX has been shown.

  As far as I know, your Intel 945GM should support DirectX 9 and because you have XP sp3, you must have at least DirectX 9 installed.

  I met the following, but it shouldn't apply to Powerpoint:

  Some such as the Intel 945 GM Intel video cards have a design limitation which may cause problems when you try to run the Source Engine games. 3D graphics kernel does not support transformation of material, light and the vertex shader to similar technologies, which is an important part of the pipeline of 3D acceleration. Instead, this functionality is emulated in software that can reduce the compatibility and performance with 3D games.

  I don't have a solution for you (assuming that DXDIAG, in fact, reports to have DirectX 9 or higher).  You can see if you install a new driver support, but if it were me, I would be first contact Acer technical support or ask your question in another forum as one of the following conditions:

  Intel graphics Forum: http://communities.intel.com/community/tech/graphics
  Forum PowerPoint: http://answers.microsoft.com/en-us/office/forum/powerpoint (select the corresponding forum for your version of Powerpoint).  Include the results of DxDiag, including the version of DirectX.  If there is something unusual about the image that causes the crash, include this info as well.

  Normally, for notebook/laptop computer, it is better to get the drivers of the mfr of computer rather than the manufacturer of the device.

  Acer drivers for your computer are here: http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=535 (you want the Intel VGA for XP driver)

  Intel has a newer driver: http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Internet+Devices&ProductLine=Netbooks&ProductProduct=Mobile+Intel%C2%AE+945GM+Express+Chipset+Family
  It's the main Intel support page: http://www.intel.com/p/en_US/support/highlights/graphics/945gm

  I tried to exclude the orfplus.exe of the DEP, but that does not solve the problem, the application always crashes when I try to print a report.

  I appreciate if someone can help me solve this problem.
