I have installed Oracle developer 10.1.2.0.2 in c:\DevSuiteHome_1 folder & installed oracel database 11g on d:\app\shah folder

I can able to connect oracle using user name system & with password.

but when i am trying to connect database using forms it gives me error ORA-12560 TNS:Protocol adapter error.

I had copied tnsnames.ora & sqlnet.ora file from oracle folder (d:\app\shah\product\11.2.0\dbhome2\network) to developer folder (c:\devsuitehome_1\network\admin)

My LSNRCTL Status is given below....
