Legacy C Pro connections are no longer works

I'm on a Windows 2003 server and I loaded 11.2.0.3 into a new House (as the new upgrade procedures is recommended). The machine is running 11.2.0.1 in production. I have not moved to the new database yet. I have not yet moved the data. The former reports of Pro C run is no longer. They are unable to connect to the database.

The code uses EXEC SQL CONNECT: username IDENTIFIED BY: password;
where username is username@dbname and password is simply the password.

ORA-12154 get... I know that it is usually a mistake in the tnsnames but file that has not changed and EVERYTHING else that uses it to connect to the database still works.

I also tried remove the @dbname the username and add using the clause to the connect statement.

A code example of something new to try would be very useful. My name sid is chssn and my tnsnames has defined chssn so I have call chssn.

ORA-12154: ALWAYS occurs only on SQL Client & not SQL * Net packets never leave client system
ORA-12154 NEVER involves the listener, the database itself or whatever it is on the DB server.
ORA-12154 occurs when the client wants to connect to a DB Server system by using a connection string.
The find operation fails because the supplied name can NOT be resolved at any remote DB.
The analogous operation would be when you wanted to call someone, but did not find their name in any directory.
The most common cause for ORA-12154 error is when the connection alias cannot be found in tnsnames.ora.
The research of the alias operation can have an impact on the content of the sqlnet.ora file. DOMAIN entry specifically.

  • My FieldChangeListeners are no longer works

    Hello

    My code is too long to post here so I'll try to explain. I've built a number of calculators with EditFields and ButtonFields, that work well. The ButtonFields have FieldChangeListeners that do things when they are clicked.

    The last calculator to build I added a few TextSpinBoxFields in a PopupScreen. I used the SpinnerDemo to help with the code. So I can make a selection of spinners OK, but now my ButtonField listeners are no longer works. When I click a button the pop-up menu main upwards instead.

    Part of the code SpinnerDemo a navigationClick() and touchEvent() overloaded, so I wonder if they caused the problem.

    If anyone can help with this I would be very happy.

    Ah, Yes. The custom button class is indeed a problem. You need to make it react to the touch of the events. To remove the context menu, you need to uncheck as well as click on the events button. Something like this should do it:

    protected boolean touchEvent(TouchEvent message) {    switch (message.getEvent()) {    case TouchEvent.CLICK:        fieldChangeNotify(1);        // fall through    case TouchEvent.UNCLICK:        return true;    }    return super.touchEvent(message);}

  • XP Pro network suddenly no longer works

    I have a home network with XP Pro and Vista Home.  It worked perfectly Friday and today (Tuesday) it won't let me access the XP machine.  I get the message "Windows cannot access (computer\dir)" the Details section: error code: 0 x 80070005 access denied.

    I have not changed anything on each machine.  There are several users and the PC have some user accounts and passwords to different levels of access to different folders.  I am set up as an administrator with full rights to everything on the PC.  Both machines have all their updates installed including SP3 on the XP machine.  The two systems are configured with static IP addresses.

    The XP machine has no problem accessing the Vista machine.  I was able to run a backup of the Vista PC to the files on the XP machine, but I have one authentication information in the backup program.  Unfortunately, it is not possible to define credentials for windows logon in Vista Home.  I have tried everything I can think about the past 5 hours including cutting the XP firewall and change the folder of shared access to everyone.  Help!  Anything with that anyone can come would be very appreciated.  I thought that maybe I could get XP to request a user name and password but I can't seem to find anything on that is.  Thanks in advance.

  • Adobe Acorobat XI pro features are no longer available

    Hello
    I use the version licensed Adobe Acrobat Pro XI from 2014. Just today, I found that the features like "Content issue", "Pages", etc. exist no more in the product. I had a chat with customer care management today and they referred me to connect with the Forums. Cat Executive also advised me to update for the DC Acrobat to get the features of back and I still have to pay for it. I understand the license that I have a perpetual license and all the features comes bundled with it should be available life long. If for some reason, that adobe does not provide features more, it is a complete violation of the license agreement.

    Ask you please help.

    This could suggest that you open the specific file is secure, digitally signed or was created using something like LiveCycle Designer, which means that you can not change it in Acrobat. It should still work with other files, however.
