Hi.
I am facing exactly same proble, but no solution till now

i installed oracle 9i release 2 on windows xp professional then i installed form 6i in different home.

i copied tnsnames.ora file from ORACLE_HOME\network\admin to forms home NET80\admin folder....

Once i installed both i can see in the PATH variable both homes then bin directory....
ORACLE_HOME/bin
FORMS_HOME/bin
in these two locations you can find sqlplus.exe file, when i try to login from the command prompt like below

sqlplus "/as sysdba"

it is not going, instead it is coming to command prompt... if i remove FORMS_HOME/bin from the PATH variable i can able to do that...just keep this problem aside.
When i try to connect oracle from the forms it is giving error like "ORA-12222 TNS no such protocol adapter...."

could you please tell me why?
what is need to do to get rid of this?

Thanks.

This is what Oracle says about it; see if it will help.
Oracle
ORA-12222: TNS:no support is available for the protocol indicated


Cause: The protocol requested in the ADDRESS portion of the connect descriptor identified through the net service name is not available. If the supplied ADDRESS is typographically correct then support for that protocol is not installed.

Action: Install support for the protocol or correct typographical error, as appropriate. Note: if the supplied address was derived from resolving the net service name, check the address in the appropriate file (TNSNAMES.ORA, LISTENER.ORA) or in the directory server.

Have you solved your problem?

I should probably merge this thread into the other to which you have been added.

Have you installed a database on this PC?

The 'common wisdom' is to install the database, get it working via SQL*Plus. Install the older version of Forms (in your case 6i), get it working by making the newer TNSNAMES.ORA match the one used by the database. Then install the newer version of Forms and get this last copy of TNSNAEMS. ORA to match the other two.

Have you solved your problem?

If not, search this forum for 'tnsnames.ora'. Install the database, get SQL*Plus working, install Forms, copy the various files from the database 'network/admin' directory to the forms 'network/admin' directory. There are many threads, read the older ones first.

What operating system are you each using?

Search this forum for 'ORA-12222 TNS no such protocol adapter'. There are numerous threads, look at the older ones first.

Don't blindly copy the database TNSNAMES.ORA file over the Forms copy. Look at it and understand what it is doing. There is also the LISTENER.ORA and another file that may also need to be changed.

David

Upd: three typos, sorry.

Get SQL*Plus working against the database, read the database tnsnames and listener files. Read the forms tnsnames and listener files. Can you see that your database is not mentioned the last two files? Modify these Forms files so that your database is mentioned in them. Restart your server - if in doubt reboot your PC.

Which part of the following don't you understand?
read the database tnsnames and listener files. Read the forms tnsnames and listener files. Can you see that your database is not mentioned the last two files? Modify these Forms files so that your database is mentioned in them. Restart your server - if in doubt reboot your PC.

For the names of the files either search this forum for 'tnsnames' and 'listener', read the older entries first, or use the 'windows explorer' and search for 'tnsnames' and 'listener'.

Hi Martin,
Thanks for your kind reply.

I have checked both tnsnames.ora and sqlnet.ora under FORM_HOME/net80/admin and ORACLE_HOME/network/admin, they are same and database is mentioned in the tnsnames.ora
Tell me martin how come oracle can able to connect from sql*plus if database name is not mentioned in tnsnames.ora file?

Do i need to create any listner.ora file? i don't think so it required because i am connecting oracle which is installed in my PC.

Shahnaz.

If your system is working then you don't need to change the 'listener', if it is not working then you do need to change the 'listener'. There are three files tnsnames, listener, and sqlnet. The copies in the database home and the forms home must have your PC's database mentioned in them.

You install the database first, you get SQL*Plus and TOAD working aginst the database, you then modify the Forms files (which aren't working properly) to contain the information that is in the database files (which is working properly).

I have done ready all but it didn't work.

1> Database (oracle 9i R2)is running in remote server.
2> I installed again in my m/c forms 6i.
3> I copied tnsnames.ora from my oracle client home to forms home
i.e ORACLE_HOME/network/admin to FORM_HOME/net80/admin

unable to resolve service name??

Could you please tell me anything else can be done apart from this?

Thanks.

Hi Martin,
step 1) i copied tnsnames.ora from oracle home to form home

step 2) to do something with sqlnet.ora

Tell me whether first step is OK?
if step is correct then i need to modify sqlnet.ora in form home.
Am i right?

Thanks.

Okay Shahnaz ... lets go back to the beginning. In February you said you are running XP on your machine, that you had installed the Oracle 9i database and that you can communicate with it via TOAD and the SQL*Plus which, I assume, is in the database home. In May you said that you are running the database on a remote server.

I know I have asked you the same questions in numerous posts but lets forget that and work our way through where you are currently.

Question 1: Do you have Oracle 9i database running on your PC?

Question 2: Can you access it via TOAD and SQL*Plus?

Request 1: Please put your 9i database versions of tnsnames.ora, listener.ora, and sqlnet.ora into a zip file labelled database_files and attach it to your next post.

Request 2: Please put your 6i forms versions of tnsnames.ora, listener.ora, and sqlnet.ora into a zip file labelled forms_files and attach it to your next post.

Lets see what you have and lets get you working.

Question 3: Have you uninstalled and / or reinstalled any of these Oracle products?

David

Sorry that I have been so long in replying. Have you solved your problem?

I know you want to use Forms but you have to test that SQL*Plus works first.

Also, use the environment variable 'tns_admin' so that you only have to maintain a single copy of the 'tnsnames.ora' file.
