I try to connect from Oracle Forms 12c to a BBDD 12.1.0.2.0 and give "ORA-12546 TNS: permission denied".
The funny thing is, I do a tnsping on the BBDD alias and if I get there.

The Oracle Forms Builder versión is:

Forms [64 Bit] Versión 12.2.1.3.0 (Producción)
Oracle Toolkit Versión 12.2.1.3.0 (Producción)
PL/SQL Versión 12.1.0.2.0 (Producción)
Oracle Procedure Builder V12.2.1.3.0 - Production
PL/SQL Editor (c) WinMain Software (www.winmain.com), v1.0 (Production)
Oracle Query Builder 12.2.1.3.0 - Production
Oracle Virtual Graphics System Versión 12.2.1.3.0 (Producción)
Oracle Tools GUI Utilities Versión 12.2.1.3.0 (Producción)

Oracle Tools Common Area Versión 12.2.1.3.0
Oracle CORE 12.1.0.2.0 Production

I execute sqlpus and the result is:

c:\Oracle\Middleware\Oracle_Home\bin>sqlplus adm_azkar/adm_azkar@SAX

You do need to have your ORACLE_HOME and PATH environment variables set appropriately. Where are you setting them? It looks as though you have at least two Oracle Homes, so relying on values picked up by your session from the registry is not going to be reliable. Better set them explicitly, in the cmd shell where you intend to run SQL*Plus and be sure, to run the correct copy of SQL*Plus.

These may help with diagnosis:

echo %ORACLE_HOME%
echo %PATH%
where sqlplus

What is BBDD? Why is it relevant to this problem.

From windows client issue command below

tnsping SAX

COPY the results from command above then PASTE all back here.

Post content from TNSNAMES.ORA file from windows client system.

BBDD means database in spanish, it is an abbreviation.

I have 2 variables ORACLE_HOME (one for forms 6i and one for forms 12c). From the sql plus I connect perfectly. The problem is when connecting to the DB from forms 12c

You can't have two variables with the same name.

You need these two variables: ORACLE_HOME and PATH. You need to set them in the same shell from which you are launching your client program. How are you doing this?

Do you know how to set and query an environment variable? Do you understand what the PATH variable does?
