I am trying to create a geodatabase(ArcSDE 10.2.1) in an Oracle database( on Windows 8. I had Installed Oracle(db),  and Oracle client( 32 bit) on the same machine and copied tnsnames.ora from ...\11.2.0\dbhome_1\NETWORK\ADMIN to ....\11.2.0\client_1\NETWORK\ADMIN. While executing Create Enterprise Geodatabase tool, I encounter error.

ORA-12537: TNS:connection closed. No extended error.Failed to execute (CreateEnterpriseGeodatabase).

I understand that ORA-12537 is specific to configuration issues in the sqlnet.ora/listener.ora files. Can you please help me to fix this.
