oci_connect still not working...I added a debug statement

errors are :
OCI8 DEBUG: OCINlsEnvironmentVariableGet at (/home/oracle/oci8/oci8-1.3.4/oci8.c:1819)
 OCI8 DEBUG L1: Got NO cached connection at (/home/oracle/oci8/oci8-1.3.4/oci8.c:1864)

 OCI8 DEBUG L1: create_spool: (0) at (/home/oracle/oci8/oci8-1.3.4/oci8.c:2686)
