Form builder hangs connecting to database

I am having a problem with forms builder. When I try to connect to a database, the builder hangs. Report builder from same home works fine, as well as sqlplus and tnsping.
The developer suite is running on windows.
Has anyone run into this problem?
thanks in advance,
Mark

Hi Mark,
What is the version of forms and database ?
Also you can try re-installing the forms.

Connect Oracle Form Builder 10g to Oracle Database 10g Express

Hi,
I'm new to Oracle.
I've installed both form builder and database 10g express.
I tried to connect form builder to HR sample database in 10g express with the following:
user name: hr
password: hr
database: hr
but I received message: ora-12154: tns could not resolve the connect identifier specified.
Can anyone help me on that? Do I need to change the tnsnames.ora?
If yes, what should I need to change in order to connect to the HR sample?
Thank you.

Yes you need to have an entry in the tnsnames.ora file for you database service name or sid. The service name or sid is usually XE unless you changed it when you installed 10g express.

Problem about using Oracle Form 6i to connect Oracle Database 10g express.

Sorry to interrupt all of you.
I have encountered a problem about using Oracle Form 6i to connect Oracle Database 10g express.
As I would like to
I use Oracle Net8 Easy Config to create a connection.
According to "tnsnames.ora", the paramater of connection is as follows;
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA = (SID = XE))
Unfortunately, when I use Oracle Net8 Easy Config to test the connection, an error message is prompted as follows:
Connecting....
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
After I google it, I still have no idea how to solve the problem. I would like to ask, could anyone mind providing some hints or solution to address the issues.
Thanks for your assistance in advance.

I don't believe the Net8 Easy Config (NEC) will create a compatible entry in the tnsnames.ora. I have Forms 6i running successfully against a 10g Express database, but I did not use the NEC - I created the entry myself. Here is the entry I use:
XE=
(DESCRIPTION=
 (ADDRESS=
 (PROTOCOL=TCP)
 (HOST=<<servername or IP address>>)
 (PORT=1521)
 (CONNECT_DATA=
 (SERVER=dedicated)
 (SERVICE_NAME=XE)
)Hope this helps,

Forms 6 not connecting with Database 10g

I can not connect Oracle forms 6 with database 10g

795192 wrote:
I can connect to sql plus but i cannot connect my forms 6 with database 10g. getting the following error:
ORA-12154: TNS: could not resolve service name=================================
ORA-12154: TNS:could not resolve the connect identifier specified
This error means one thing, and one thing only. The client could not find the specified entry in the tnsnames.ora file being used.
As a follow-on to that statement, remember that when you use a dblink, the database in which the link is defined is acting as a client to the database that is the target of the link. So in this case, the tnsnames.ora file on the host of your source should have an entry for your target db, as defined in the db_link.
And for the umpteenth time ... this error has NOTHING to do with the status of a listener. The connection request never got far enough to reach a listener. If anyone tells you to check a listener in response to ora-12154, they are not paying attention, or do not understand how TNS works. This error is the equivalent of not being able to place a telephone call because you don't know the number of the party you want to reach. You wouldn't debug that situation by going to the other guy's house and testing his telephone, or by going to the phone company and testing the switchboard. And you don't debug a ORA-12154 by checking the listener. If I had a top ten list of "Incredibly Simple Concepts (tm)" that should be burned into the brain of everyone who claims to be an Oracle DBA, it would include "ORA-12154 Has Nothing To Do With The Listener".
=================================
A couple of important points.
First, the listener is a server side only process. It's entire purpose in life is to receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It creates the connection. It doesn't sustain the connection. One listener, with the default name of LISTENER, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners or to name the listener as if it belongs to a particular database. That would be like the telephone company building a separate switchboard for each customer.
Second, the tnsnames.ora file is a client side issue. It's purpose is for address resolution - the tns equivalent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
Assume you have the following in your tnsnames.ora:
larry =
(DESCRIPTION =
 (ADDRESS_LIST =
 (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
 (CONNECT_DATA =
 (SERVICE_NAME = curley)
)Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larrytns will look in your tnsnames.ora for an entry called 'larry'. Next, tns sends a request to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the request arrives at port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, you'll be connected.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"

Help: FORMS SERVER cannot connect to database (forms patch9)

Hi:
I've installed oracle 9i database and oracle 9ias 1.0.2.2.2a.
I configured FormsServlet and it's working very well as i suceed my test in http://machina.domain/servlet/oracle.forms.servlet.ListenerServlet!
The problem is that i cannot connect to the database and i got the error ORA-12203 TNS: Unable to connect to destination!
I've changed jserv.properties as recommended in 9ias 10222 release notes by commenting the wrapper.env=ORACLE_HOME in OJSP because it conflicts with forms server home.
I've read all about this, and i still cannot connect to the database.
I'm using a forms servlet configuration with IE JVM.
If anyone can help me... i apreciate it!
By the way in my jserv.properties forms server config i have:
# Oracle Forms and Reports Servers
wrapper.classpath=C:\ORACLE\806\forms60\java\f60srv.jar
wrapper.classpath=C:\ORACLE\806\forms60\java
If i have this the Test native method call (JNI) fails, but forms server keeps running. The error is:
Calling RunformProcess.nInitLib()...
RunformProcess.nInitLib() failed:

Your server configuration needs correcting. Please refer to the Forms documentation for details

Can Forms Builder access non-Oracle Database?

Does any one know whether Pracle Forms can access othe non-Oracle database via ODBC or JDBC to MS Access or MySQL?

12282,
In general, HTML DB gives you access to Oracle database facilities. These include heterogeneous services. Please search this forum for keyword "heterogeneous" and you can follow the threads that interest you.
As for the comparison with brain surgery, I'd rank them about the same in terms of raw thrill.

Form Builder crashes while saving .fmb file when connected to db

Hi,
I am getting error The instruction at "0x679c352c" referenced memory at "0x0000001c". The memory could not be "read".
Forms version is 6.0.8.11.3 and database version is 10.2.0.3.0
I am doing the following steps:
1) Open .fmb file in forms builder
2) Connecting to database
3) Making some changes in form
4) Compiling (Ctrl+Shift+K) and generating form (Ctrl+t)
5) Saving form <--- Here I am getting the error and form crashes
If I do not connect to database then builder is allowing me to save the file
1) Open .fmb file in forms builder
2) Making some changes in form
3) Saving form (Successful)
I did some exercise just as a guess that may some part of the form is causing this error. I full expanded all components of the form i.e. blocks, canvases, triggers etc.
This exercise produced that 3 program units were giving same error while full expending those. I deleted those 3 program units and re-created them. Now it is not showing me this memory error while full expanding all program units. I can now fully expand my full form.
But I am still getting this error while saving the changes when I am connected to database.
Please help.

Ronald,
I was able to connect to a database with Forms 11g by adding an Environment variable TNS_ADMIN and pointing this to the directory where the sqlnet.ora and tnsnames.ora files are located. I was unable to find a Net Configuration Assistant in Forms 11g and placing a copy of .ora files in the /%11G HOME/NETWORK/ADMIN didn't work either. Only after I added the environment variable was I able to connect.
There might be a "More Appropriate" solution, but this is what worked for me. We are just now testing 11g, but are still developing with 10g R2.
Hope this helps,
Craig B-)

Can I connect Oracle Forms Builder 10g to MS Access Database

Hi,
I have Oracle forms builder installed in my PC. I downloaded the Oracle Database Server from the oracle website and installed that as well. But due to the installation of Database server, my system has become very slow. In order to avoid this I wanted to know if I can connect the forms builder to MS Access Database.
Also, using ODBC I have created a database in my D:\ drive.
If using MS access as a database is possible, then kindly guide me how to proceed with it.
Thanks,

Hi Francois,
Thanks for your reply.
I have been working on Oracle forms from the past 1 year. I wanted to increase my expertise at the subject so thought I'll install it at my home and then try out developing and running a few small forms. So, in order to do this I downloaded and installed Developer Suite and database server. After installing the database server the system became very slow, as I mentioned earlier. Once I uninstalled the server, my system speed was back to normal. My system configuration is:
512 MB ram, Intel Pentium 4 2.66 Ghz processor, Windows XP service pack 3,1 CPU.
My requirement is very minimal. I just want a simple database where I can create tables, store data and connect form. If you have a have any other suggestion for my requirement then kindly help me in this regard.
In the meantime I'll act on your suggestion and try and install the XE server.
Thanks.
Shashank

Oracle Forms Builder 10.1.2.3 hangs when opening canvas

Hi
I created a form with 1 master, 2 details and a tab panel. Now I can't open the canvas. Each time I try to open it Oracle Form Builder hangs. What can I do?

I've installed Oracle Developer Suite (ODS) 10g R2 on numerous Windows 7 systems and have only encountered an issue with Forms Builder crashing a couple of times. Each time, I've been able to resolve the problem by modifying the OS PATH environment variable to ensure there is not a conflict between Oracle versions. If you only have ODS 10g installed, this should not be a problem, but if you have different versions of Forms installed - this could very well be the problem. My you might want to take a look at the OS PATH and make sure all Windows related directories are listed first. Then list the ODS directories second and lastly, list everything else. Oracle has a bad habit of putting it's program directories before the operating system directories.
It is also possible that your installation media is bad since your install is crashing in Windows XP mode as well. That being the case, you may want to download the installer again.
