Is it possible to connect to a db without modifying tnsnames.ora neither configuration

[John Willmer]

I haven't been able to connect ot a new db because I don't have permissions to modify the tnsnames.ora file.

Could I connect with the whole information at the moment to create a new session?

Perhaps you can use the EZCONNECT naming method? It uses the following format for the database specification:

host[ort]/database

The default port number is 1521, in which case it can be omitted:

host/database

Note that EZCONNECT needs to be enabled in the SQLNET.ORA file.
